Differentiated instruction is an approach that centers on the fact that every student is different and shapes the teaching process according to this reality. Students in the learning environment differ from each other in terms of characteristics such as prior knowledge, interest, needs, learning style, socio-cultural background, cognitive-affective-psychomotor readiness. In order for students with different characteristics to benefit from education in the best way, it is necessary to diversify education in terms of content, teaching-learning process and measurement-evaluation dimensions, taking these (...) differences into account. In this diversification, students' readiness, interest and learning profiles are taken into account as a whole. Although educational programs are prepared by taking the similarities between individuals into account in practice, teachers are expected to diversify the process by taking the individual differences of the students into account and design different learning paths for students with different characteristics. One of the areas that needs to be planned and implemented with a differentiated teaching approach within formal education is religious education. Differentiated religious teaching is to diversify religious teaching in terms of content, learning-teaching process and measurement and evaluation dimensions, taking the individual differences of students into account such as their prior religious knowledge, interest and attitudes towards religion, cultural affiliations and learning profiles. In this study, the self-efficacy perceptions of Religious Culture and Moral Knowledge (“Din Kültürü ve Ahlâk Bilgisi”, abb. DKAB in Turkish) teachers towards differentiated teaching were examined. Determining the self-efficacy perceptions of DKAB teachers regarding differentiated instruction is important in terms of providing information about their success in planning, implementing and evaluating according to differentiated instruction in the Religious Culture and Moral Knowledge course. The research sought answers to the following questions: 1. What are DKAB teachers' self-efficacy perceptions towards differentiated instruction? 2. Is there a significant relationship between DKAB teachers' self-efficacy perceptions towards differentiated instruction and teachers' gender, age, years of service, graduated higher education program and the type of school they work in? The research is a descriptive study and is of quantitative type and survey model. The population of the research consists of DKAB teachers working in primary and secondary education institutions in the 2nd semester of the 2021-2022 academic year. The sample of the research consists of 425 DKAB teachers selected from the population using the appropriate sampling method. Differentiated Instruction Self-Efficacy Scale developed by Mutlu, Öztürk and Aktekin was used to collect the data used in the research. The data collected in the study was analyzed using the SPSS 25.0 package program. According to the findings obtained in the study, DKAB teachers' self-efficacy perceptions regarding differentiated instruction are at a high level. The characteristics of DKAB teachers' age, years of service, and the type of school they work in do not have a significant effect on teachers' self-efficacy perceptions regarding differentiated instruction. There is a significant relationship between DKAB teachers' gender and the characteristics of the higher education program they graduated from and their self-efficacy perceptions. Male teachers consider themselves more competent in differentiated instruction. The self-efficacy perceptions of the teachers who graduated from the primary education DKAB Teaching program are at a higher level than the teachers who graduated from the theology (Ilahiyat) program, which is described as the faculty of theology. It is thought that the research will contribute to the field of differentiated religious teaching. (shrink)

One way in which the practice of inclusion can be actualised in classrooms is through the use of consistent, appropriate differentiated instruction. What remains elusive, however, is insight into what teachers in different contexts think and believe about differentiation, how consistently they differentiate instruction and what challenges they experience in doing so. In the study reported on here high school classrooms in a private and a government school in Lesotho were compared in order to determine teachers’ thoughts and beliefs about (...) differentiation, the frequency of differentiated instruction, and the challenges faced by teachers who implement this inclusive practice. Sampled teachers offered their views on what they understood differentiated instruction to be, the frequency of differentiated instruction, and identified challenges via an administered questionnaire. Data analysis was based on frequency counts and bar charts for comparative purposes. Findings indicate that private school teachers have a higher frequency of differentiated teaching practice, with time constraints indicated as the main challenge. Government school teachers had a lower frequency of differentiation, and identified a lack of resources, and the learner-teacher ratio as challenges, among others. In the study we highlighted the critical role that private schools can play in the national call for the implementation of inclusive teaching in Lesotho, in terms of active collaboration with surrounding government schools. Private schools, with their resources and access to professional development opportunities, can become catalysts in the implementation of inclusive teaching practices. (shrink)

Negative conditional stimulus valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person was paired with an aversive US, while another was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the (...) CS− poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS−. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding. (shrink)

Over the past two decades, there has been a marked increase in the number of students with mild disabilities who receive social studies instruction in the general education classroom. This research uses the seminal 1994 Passe and Beattie study as a comparative referent to examine current instructional strategies used to teach such students. The current study sought to answer: What instructional practices do contemporary general educators use to teach social studies to students with disabilities? And have these practices changed in (...) twenty-years? Comparative and comparison results are provided with suggestions to differentiate social studies instruction to meet the learning needs of students with mild disabilities. (shrink)

The purpose of this study is to elucidate various practices for the structuring of images on an ultrasound monitor during prenatal ultrasound examinations. This study focuses on the practices that healthcare providers employ to invite pregnant women to differentiate a gray-tone image on the ultrasound monitor from the image’s background. In sequential environments in which pregnant women display difficulty in differentiating an image on the screen in response to the healthcare provider’s invitation, the healthcare provider employs practices that require additional (...) bodily involvement to structure the images on the screen. Furthermore, on certain occasions, the healthcare provider also points to a particular abdominal location with the ultrasound transducer, which is held against the abdomen to produce the very image being differentiated. This study demonstrates that the image on the ultrasound monitor is intrinsically embodied and spatially and modally distributed. In addition, the study suggests an interaction-organizational ground for an aspect of the ‘personification of the fetus’ through obstetric ultrasound. (shrink)

This target article examines the clinical and experimental evidence for a role of peripheral and central hyperexcitability in persistent pain in four key areas: cutaneous hyperalgesia, referred pain, neuropathic pain, and postoperative pain. Each suggests that persistent pain depends not only on central sensitization, but also on inputs from damaged peripheral tissue. It is instructive to think of central sensitization as comprised of both an initial central sensitization and an ongoing central sensitization driven by inputs from peripheral sources. Each of (...) these factors, initial sensitization, ongoing central sensitization, and inputs from peripheral sources, contributes to the net activity in dorsal horn neurons and thus influences the expression of persistent pain or hyperalgesia. Since each factor, peripheral inputs and central sensitization (initial or ongoing), can contribute to both the initiation and maintenance of persistent pain, therapies should target both peripheral and central sources of pathology.

Coaching is a systematic and goal-oriented one-on-one intervention by a coach aimed to guide clients in their professional and personal development. Previous research on coaching has demonstrated effects on a number of positive outcomes, including well-being and performance, yet little is known about the processes that underlie these outcomes, such as the type of questions coaches use. Here, we focus on three different types of coaching questions, and aim to uncover their immediate and sustained effects for affect, self-efficacy, and goal-directed (...) outcomes, using a between-subjects experiment. One hundred and eighty-three medical residents and PhD students from various medical centers and healthcare organizations in the Netherlands were recruited to participate in a self-coaching writing exercise, where they followed written instructions rather than interacting with a real coach. All participants were randomly allocated to one of three conditions: either one of two solution-focused coaching conditions or a problem-focused coaching condition. Self-report questionnaires were used to measure key outcomes of coaching, that is positive and negative affect, self-efficacy, goal orientation, action planning and goal attainment. Two follow-up measurements assessed if the effects of the self-coaching exercise led to problem-solving actions within an initial follow-up period of 14 days and a subsequent follow-up period of 10 days. Findings showed that participants experienced more positive affect, less negative affect, and higher approach goal orientation after the solution-focused coaching exercise compared to the problem-focused coaching exercise. In all conditions, goal attainment increased as a consequence of the self-coaching intervention. We discuss the implications of our findings for the science and practice of contemporary coaching.

T‐bet and Eomes are two related transcription factors (TFs) that regulate the differentiation of cytotoxic lymphocytes such as Natural Killer (NK) cells and CD8 T cells. Recent genome‐wide analyses suggest they have complementary roles in instructing the transcriptional program of NK cells, although their DNA binding sites appear to be very similar. In this essay, we discuss the mechanisms that could specify their action, addressing their expression profile, the cofactors they interact with, as well as their roles in the epigenetic (...) regulation of chromatin accessibility. Based on the recent literature on these TFs, we propose different models to describe how they regulate gene expression in NK cells at steady state, or in the context of activation or exhaustion. We also discuss recent findings in the field of CD8 T cell differentiation and residency, where Eomes and T‐bet appear to be major regulators, and the parallels that can be drawn between mechanisms of NK and CD8 T cell differentiation and trafficking.

Recent calls for reinstituting mandatory home economics education have emphasized its potential to advance gender egalitarian aims. The thought is that, because women’s disproportionate performance of caregiving and household labor is partially caused by gender socialization that better prepares women than men for such work, we can disrupt gender inegalitarian work distributions by preparing everyone for the sort of work in question. The curricula envisioned in these calls are gender-neutral, in the sense that they recommend identical educational interventions for all (...) genders. By exploiting a parallel between gender-neutral educational policies and gender-neutral family leave policies, we argue first that gender-neutral home economics instruction is unlikely to advance gender egalitarian aims, and may in fact reinforce the very outcomes it is meant to disrupt. However, we further argue that a more radical home economics curriculum could avoid these difficulties. To the extent that we value educational interventions as a possible means for advancing gender egalitarian aims, we have good reason to seriously consider adopting a gender non-neutral program in which all and only boys receive mandatory caregiving instruction.

Conversational implicatures (CIMs) are implied by the speaker in context rather than being linguistically encoded, and learners’ inability to infer the intended meaning, if not remedied through instruction (or mediation), leads to communication breakdowns. Given this premise, the current study aimed to examine effects of classroom praxis-based instruction adjusted to EFL learners’ Zone of Proximal Development (ZPD) on their comprehension of CIMs. Participants were 36 Iranian high school students in 2 classrooms, assigned to experimental and comparison groups. A 20-item CIM (...) test was administered at pretest and posttest times to collect the data. Microgenetic trajectories were also traced through audio-recorded role-plays and social interactions within the ZPD setting. ZPD-adjusted mediational instruction on CIMs was given based on a multi-level regulatory scale and a view of microgenetic development along an other-to self-regulated functioning continuum. In the non-ZPD setting, mainstream teacher-fronted instruction was employed. ANCOVA results revealed differential instructional effects in favor of the praxis-based mediational setting. Microgenetic learning episodes also portrayed how collectively-mediated, ZPD-activated learning led to L2 learners’ progressively improved comprehension of CIMs. The findings suggest that comprehension (and perhaps production) of L2 CIMs can be improved through praxis-oriented co-construction of pragmatic knowledge through collaborative engagement with communicative activity.

The potential of the vertebrate limb as a model system to study developmental mechanisms is particularly well illustrated by the analysis of the Hox gene network.

Their functional organisation during both limb and trunk development are very similar and seem to involve the progressive activation in time, along the chromosome, of a battery of genes whose products could differentially instruct those cells where they are expressed. This process (...) may be common to all organisms that develop according to an anterior‐posterior morphogenetic progression.

ObjectiveWe aimed to explore profiles of subgroups of United States students based on their motivational and affective characteristics and investigate the differences in math-related behaviors, persistence, and math achievement across profiles.MethodWe used 1,464 United States students from PISA 2012 United States data in our study. First, we employed latent profile analysis and secondary clustering to identify subgroups of students based on motivational and affective factors. Next, we used regression to compare differences in math behavior, persistence, and achievement among all identified (...) subgroups.ResultsWe found five distinct groups of students with different patterns of motivation and affection. The subgroup of students with the lowest math anxiety and the highest motivation levels showed the highest math achievement and levels of persistence. The groups with high math interest, math self-concept, and instrumental motivation showed the most frequent math-related behaviors.ConclusionsOur findings reveal the complexity of the students’ motivational and affective profiles. Our findings are significant for teachers and educators to understand the diversity of students and provide theoretical and practical support for individualized and differentiated instruction.

This study aims to examine whether recent educational attempts to prepare students for the future can open up the future, using South Korea’s ‘high school credit system’ as an example. To provide differentiated instruction that recognizes differences and maximizes students’ potential, the Korean government recently launched a ‘high school credit system.’ The primary goal of this system is to assist students in identifying their strengths and interests, selecting courses for them to pursue, and following their plans independently. The system appears (...) to respect each student’s unique personality and value the self-dominance of the liberating subject. Ironically, however, it expects students to map their lives according to ‘given’ or molar identitarian categories for self-formation, thereby representing already constructed life forms. It subjugates students’ potential by linking subjective formation to society’s dominant codes and deploying the forged self within existing social structures. To avoid limiting students’ potential, it is essential to refrain from defining ‘the self’ as a given and fixed construct and restricting education solely to courses that match its current characteristics. Education for a future should promote a flexible educational journey that accommodates changes in interests and passions as they evolve over time. (shrink)

The appropriate methodology for psychological research depends on whether one is studying mental algorithms or their implementation. Mental algorithms are abstract specifications of the steps taken by procedures that run in the mind. Implementational issues concern the speed and reliability of these procedures. The algorithmic level can be explored only by studying across-task variation. This contrasts with psychology's dominant methodology of looking for within-task generalities, which is appropriate only for studying implementational issues.The implementation-algorithm distinction is related to a number of (...) other “levels” considered in cognitive science. Its realization in Anderson's ACT theory of cognition is discussed. Research at the algorithmic level is more promising because it is hard to make further fundamental scientific progress at the implementational level with the methodologies available. Protocol data, which are appropriate only for algorithm-level theories, provide a richer source than data at the implementational level. Research at the algorithmic level will also yield more insight into fundamental properties of human knowledge because it is the level at which significant learning transitions are defined.The best way to study the algorithmic level is to look for differential learning outcomes in pedagogical experiments that manipulate instructional experience. This provides control and prediction in realistically complex learning situations. The intelligent tutoring paradigm provides a particularly fruitful way to implement such experiments.The implications of this analysis for the issue of modularity of mind, the status of language, research on human/computer interaction, and connectionist models are also examined.

This article is intended to guide online course developers and teachers. A brief review of the literature on the misconceptions of beginning online teachers reveals that most accept the notion that putting one’s lecture notes online produces effective learning, or that technology will make education more convenient and cost-effective for all concerned. Effective online learning requires a high level of responsibility for learning on the part of students and a reduction of the teacher-student power differential. This, in turn, has (...) major implications for faculty and course development, student selection criteria, the cost of instruction, and the outcomes of education. Effective online teaching focuses on processes of learning rather than outcomes, and is consistent with modern principles of learning that emphasize focusing on issues of high interest to learners, teaching students to use skills of active and effective learning, providing prompt feedback, and enabling students to establish learning goals and employ alternative paths to achieving those goals. Multiple ways of operationalizing these goals online are presented. Tips are offered concerning selection of students who are capable of benefiting from the online experience, developing curriculum that is user-friendly, using resources that stimulate good writing and critical thinking, and limiting class size to a manageable number.

In cultural as well as social science studies of discourses (e.g. of discourses on climate change), the concept of narrative is used in a very broad sense – as an umbrella term that lacks analytical accuracy. From the perspective of linguistics, it seems obvious to acknowledge five elementary generic patterns. In addition to narration, linguists differentiate between argumentation, description, explication and instruction. Each of these patterns fulfils a different basic pragmatic function. This article tries to make clear and justify why (...) it is important, both theoretically and practically, to make a distinction between these five generic patterns. It is argued and shown that narrativization tends to go hand in hand with a relief of action, historicization, potential fictionalization, subjectivization and relativization. With respect to discourses on the climate crisis, these prototypical characteristics of narratives undermine both scientific attempts to justify claims of truth relating to the existence, causes and consequences of global warming as well as practical attempts to motivate people to adopt a more sustainable lifestyle.

One challenge in developing an account of the nature of epistemic blame is to explain what differentiates epistemic blame from mere negative epistemic evaluation. The challenge is to explain the difference, without invoking practices or behaviors that seem out of place in the epistemic domain. In this paper, I examine whether the most sophisticated recent account of the nature of epistemic blame—due to Jessica Brown—is up for the challenge. I argue that the account ultimately falls short, but does so in (...) an instructive way. Drawing on the lessons learned, I put forward an alternative approach to the nature of epistemic blame. My account understands epistemic blame in terms of modifications to the intentions and expectations that comprise our “epistemic relationships” with one another. This approach has a number of attractions shared by Brown’s account, but it can also explain the significance of epistemic blame. (shrink)

Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, (...) 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website. (shrink)

An implicit association test (IAT) measures differential association of 2 target concepts with an attribute. The 2 concepts appear in a 2-choice task (e.g., flower vs. insect names), and the attribute in a 2nd task (e.g., pleasant vs. unpleasant words for an evaluation attribute). When instructions oblige highly associated categories (e.g., flower + pleasant) to share a response key, performance is faster than when less associated categories (e.g., insect + pleasant) share a key. This performance difference implicitly measures (...) differential association of the 2 concepts with the attribute. In 3 experiments, the IAT was sensitive to (a) near-universal evaluative differences (e.g., flower vs. insect), (b) expected individual differences in evaluative associations (Japanese + pleasant vs. Korean + pleasant for Japanese vs. Korean subjects), and (c) consciously disavowed evaluative differences (Black + pleasant vs. White + pleasant for self-described unprejudiced White subjects).

The ArgumentThis essay attempts to show the decisive importance of the “scientific discipline” for any historical or sociological analysis of modern science. There are two reasons for this:1. A discontinuity can be observed at the beginning of modern science: the “discipline,” which up until that time had been a classificatorily generated unit of the ordering of knowledge for purposes of instruction in schools and universities, develops into a genuine and concrete social system of scientific communication. Scientific disciplines as concrete systems (...) (Realsysteme) arise as a result of (a) the communicative stabilization of “scientific communities” at the end of the eighteenth century and the formation of “appropriate” roles and organizational structures (in universities); (b) the structural differentiation of the new scientific disciplines from the established professions (law, theology, medicine) in Europe; (c) the formation of scientific communication in the standardized form of scientific publication; the distinction of the separate action-type “scientific research” and the differentiation of these two elementary acts of all future scientific endeavor in relation to each other.2. The scientific discipline as primary unit of the internal differentiation of science has, since its genesis, been stabilized by two conditions: (a) The fact of a science differentiated into a plurality of (competing, mutually stimulating) disciplinary perspectives becomes the chief causal factor underlying the developmental dynamism of modern science; (b) Similar to the way in which the discipline functions as a cognitive address within the system of science, science also links the discipline up as a structural unit (utilized in both systems) with curricular structures in the system of education — i.e., it is stabilized by the central system/environment relation of science.

ICAP is a theory of active learning that differentiates students’ engagement based on their behaviors. ICAP postulates that Interactive engagement, demonstrated by co‐generative collaborative behaviors, is superior for learning to Constructive engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits of Active or Passive engagement, marked by manipulative and attentive behaviors, respectively. This paper discusses a 5‐year project that attempted to translate ICAP into a theory of instruction using five successive measures: (a) teachers’ understanding of ICAP after (...) completing an online module, (b) their success at designing lesson plans using different ICAP modes, (c) fidelity of teachers’ classroom implementation, (d) modes of students’ enacted behaviors, and (e) students’ learning outcomes. Although teachers had minimal success in designing Constructive and Interactive activities, students nevertheless learned significantly more in the context of Constructive than Active activities. We discuss reasons for teachers’ overall difficulty in designing and eliciting Interactive engagement. (shrink)

Difficulties understanding speech form one of the most prevalent complaints among older adults. Successful speech perception depends on top-down linguistic and cognitive processes that interact with the bottom-up sensory processing of the incoming acoustic information. The relative roles of these processes in age-related difficulties in speech perception, especially when listening conditions are not ideal, are still unclear. In the current study, we asked whether older adults with a larger working memory capacity process speech more efficiently than peers with lower capacity (...) when speech is presented in noise, with another task performed in tandem. Using the Eye-tracking of Word Identification in Noise Under Memory Increased Load an adapted version of the “visual world” paradigm, 36 older listeners were asked to follow spoken instructions presented in background noise, while retaining digits for later recall under low or high memory load. In critical trials, instructions directed listeners’ gaze to pictures of objects whose names shared onset or offset sounds with the name of a competitor that was displayed on the screen at the same time. We compared listeners with different memory capacities on the time course for spoken word recognition under the two memory loads by testing eye-fixations on a named object, relative to fixations on an object whose name shared phonology with the named object. Results indicated two trends. For older adults with lower working memory capacity, increased memory load did not affect online speech processing, however, it impaired offline word recognition accuracy. The reverse pattern was observed for older adults with higher working memory capacity: increased task difficulty significantly decreases online speech processing efficiency but had no effect on offline word recognition accuracy. Results suggest that in older adults, adaptation to adverse listening conditions is at least partially supported by cognitive reserve. Therefore, additional cognitive capacity may lead to greater resilience of older listeners to adverse listening conditions. The differential effects documented by eye movements and accuracy highlight the importance of using both online and offline measures of speech processing to explore age-related changes in speech perception.

Developmental biology is a theory of interpretation. Developmental signals are interpreted differently depending on the previous history of the responding cell. Thus, there is a context for the reception of a signal. While this conclusion is obvious during metamorphosis, when a single hormone instructs some cells to proliferate, some cells to differentiate, and other cells to die, it is commonplace during normal development. Paracrine factors such as BMP4 can induce apoptosis, proliferation, or differentiation depending upon the history of the responding (...) cells. In addition, organisms have evolved to alter their development in response to differences in temperature, diet, the presence of predators, or the presence of competitors. This allows them to develop the phenotype, within the limits imposed by the genotype, best suited for the immediate habitat of the organism. Most developing organisms have also evolved to expect developmental signals from symbionts, and these organisms develop abnormally if the symbiont signals are not present. Thus Hoffmeyer’s “vertical semiotic system” of genetic communication and “horizontal semiotic system” of ecological communication are integrated during development. (shrink)

This article reports two studies investigating the relationship between emotional feelings and respiration. In the first study, participants were asked to produce an emotion of either joy, anger, fear or sadness and to describe the breathing pattern that fit best with the generated emotion. Results revealed that breathing patterns reported during voluntary production of emotion were (a) comparable to those objectively recorded in psychophysiological experiments on emotion arousal, (b) consistently similar across individuals, and (c) clearly differentiated among joy, anger, fear, (...) and sadness. A second study used breathing instructions based on Study 1's results to investigate the impact of the manipulation of respiration on emotional feeling state. A cover story was used so that participants could not guess the actual purpose of the study. This manipulation produced significant emotional feeling states that were differentiated according to the type of breathing pattern. The implications of these findings for emotion theories based on peripheral feedback and for emotion regulation are discussed. (shrink)

This essay takes into account the pedagogical reform for the poor proposed in England by Andrew Bell, Joseph Lancaster and Patrick Colquhoun between Eighteenth and Nineteenth century. Differentiating individuals and reproducing social order through the implementation of a pedagogical plan is a response both to the excessive expectations of well-being raised among the English poor by the Revolution in France, and to the uncontrolled spread of crime and undisciplined behaviours in the new manufacturing districts. This is why social reformers looked (...) at the pedagogical reform of mutual instruction as a way to build the conditions of reproduction of social differences: the plans proposed by Bell and Lancaster, based on emulation, competition and merit, are supported by Colquhoun because they offer a possible solution for the problems of crime and immoral behaviour. «The order of Merit», triggered by emulation, distinction and reward, thus become the main tool of influencing poor’s expectations so to predict and discipline their conduct as future waged workers.

Building on Dor’s theory of language as a social technology for the instruction of imagination, I suggest that autobiographical memory evolved culturally as a response to the problems of false memory and deliberate deceit that were introduced by that technology. I propose that sapiens’ linguistic communication about past and future events initially occurred in small groups, and this helped to correct individual memory defects. However, when human groups grew in size and became more socially differentiated, and movement between groups prevented (...) story-verification, misattributions of events became more common. In such conditions individuals with better autobiographical memory had an advantage because they could evaluate their own contents and sources of information, as well as that of others, more accurately; this not only benefitted them directly, but also improved their reliability as social partners. Autobiographical memory thus evolved in the context of human linguistic communication through selection for communicative reliability. However, the advantages of imagination, which enables forward-planning and decision-Making, meant that memory distortions, although controlled and moderated by autobiographical memory, could not be totally eradicated. This may have driven the evolution of additional forms of memory control involving social and linguistic norms. I interpret the language and the social norms of the Pirahã as the outcome of the cultural-evolutionary control of memory distortions. Some ways of testing aspects of this proposal are outlined.

Significant progress in the molecular investigation of endogenous bioelectric signals during pattern formation in growing tissues has been enabled by recently developed techniques. Ion flows and voltage gradients produced by ion channels and pumps are key regulators of cell proliferation, migration, and differentiation. Now, instructive roles for bioelectrical gradients in embryogenesis, regeneration, and neoplasm are being revealed through the use of fluorescent voltage reporters and functional experiments using well‐characterized channel mutants. Transmembrane voltage gradients (Vmem) determine anatomical polarity and function as (...) master regulators during appendage regeneration and embryonic left‐right patterning. A state‐of‐the‐art recent study reveals that they can also serve as prepatterns for gene expression domains during craniofacial patterning. Continued development of novel tools and better ways to think about physical controls of cell‐cell interactions will lead to mastery of the morphogenetic information stored in physiological networks. This will enable fundamental advances in basic understanding of growth and form, as well as transformative biomedical applications in regenerative medicine. (shrink)

Transparency is important in today’s business environment. The use of euphemisms decreases transparency yet is increasing in business and business education. This study examines the effects of euphemism on people’s attitudes toward actions and their intentions to perform those actions. It also measures the effect of oversight on attitudes and behavioral intentions. Using a 2 × 2 experimental design, we measured participants’ attitudes by employing a semantic differential scale and behavioral intentions by using a simple yes/no question regarding the (...) action described. A questionnaire with 20 brief scenarios provided the euphemistic versus non-euphemistic condition. Oversight versus non-oversight conditions were manipulated through instructions to participants. Hypotheses regarding the effects of euphemism were supported; participants were both more likely to rate an action as appropriate and to indicate they would take that action when stated euphemistically. Oversight did not have a significant effect on attitude toward the action, but did significantly affect participants’ intentions to take that action. Findings suggest both managerial and ethical implications for businesses. Greater transparency includes more straight talk and less euphemism and is recommended to ensure employees’ understanding and implementation of ethical business actions. (shrink)

An analysis of students’ difficulties for a curricular topic may help the educator to gain better insight into students’ reasoning about that topic which is a prerequisite for high-quality teaching. The purpose of this study was to demonstrate how distractor analysis may be used for identifying students’ difficulties in a certain topic. In order to be in position to perform invariant measurement and to easily relate students’ difficulties to their achievement levels, we decided to take a Rasch modeling approach. Our (...) study included 14 wave optics items and 286 students from five universities in Slovenia, Croatia, and Bosnia and Herzegovina. Rasch modeling was used to estimate item and student measures, as well as to create option probability curves which allowed us to relate students’ achievement levels to the choice of individual distractors. It has been found that all 14 included items function in line with the Rasch model. In 10 out of 14 items there were distractors chosen by at least 25% of students. For several out of these 10 items, the option probability curves indicated that attractiveness of individual distractors depended on students’ ability levels. We could conclude that the Rasch-based distractor analysis may provide very useful information for differentiation of physics instruction. Analiza studentskih poteškoća vezanih za određenu nastavnu temu može pomoći predavaču u stjecanju boljeg uvida u studentsko razumijevanje određene teme, što je preduvjet za visokokvalitetnu nastavu. Svrha ovog istraživanja sastojala se u demonstriranju načina na koji analize ometača mogu biti iskorištene za identificiranje studentskih poteškoća u određenom području. Kako bismo mogli provoditi invarijantna mjerenja i lako povezati studentske poteškoće s razinama njihovih postignuća, odlučili smo se studiju provesti u okviru Rasch formalizma. Naše istraživanje obuhvatilo je 14 zadataka iz područja valne optike i 286 studenata s pet sveučilišta u Sloveniji, Hrvatskoj te Bosni i Hercegovini. Rasch modeliranje korišteno je za procjenu težine zadataka i sposobnosti studenata, kao i za kreiranje krivulja vjerojatnosti ponuđenih opcija što nam je omogućilo povezivanje razine razumijevanja studenata s izborom pojedinačnih ometača. Utvrđeno je da svih 14 zadataka funkcionira u skladu s Rasch modelom. Za 10 zadataka imali smo ometače koje je odabralo najmanje 25 % studenata. Kod nekoliko od ovih 10 zadataka krivulje vjerojatnosti ponuđenih opcija ukazuju na to da atraktivnost pojedinačnih ometača ovisi o razinama sposobnosti učenika. Možemo zaključiti da analiza ometača primjenom Rasch modeliranja može dati vrlo korisne informacije za diferencijaciju nastave fizike. (shrink)

Let us begin with the simple observation that applied mathematics can be very tough! It is a common occurrence that basic physical principle instructs us to construct some syntactically simple set of differential equations, but it then proves almost impossible to extract salient information from them. As Charles Peirce once remarked, you can’t get a set of such equations to divulge their secrets by simply tilting at them like Don Quixote. As a consequence, applied mathematicians are often forced to (...) pursue roundabout and shakily rationalized expedients if any useful progress is to be made. Often these provisional and quasi-empirical procedures within applied mathematics loom large in motivating the “anti-realist” or “anti-unificationist” conclusions of Nancy Cartwright and allied authors.

The mechanisms of Darwinian theory applied at the cellular level can explain the embryogenesis of an organism. On the one hand, DNA is not the bearer or carrier of a program composed of rigid instructions, in which the adult organism is « written », in advance. It is a generator of diversity that functions in a probabilistic fashion and thus enables cells to change states without being guided by signals. On the other hand, the environment is not only that (...) which is external to the organism. It exists within the embryo inasmuch as it constitutes the micro-environment of the cell. It determines the concentration of metabolites to which the cell has access and which enable it to multiply. In a colony of cells there are numerous variations in the composition of this microenvironment. Cells exchange the products of their metabolism. They use what their neighbours provide them. By means of their probabilistic functioning, they adapt to changing life conditions by activating the necessary proteins, whence the cellular differentiation generating the tissue of which an adult being is composed. In this theory, the embryo is not the passive object subject to the cumulative determinisms of the genome and the environment. These are integrated into a single mechanism. The cell is the fundamental level which constructs the living being by an active process of Darwinian selection. By bringing together phylogeness and ontogenesis in one explanatory model, cellular Darwinism allows us to get rid of the old concepts of purposiveness and formal cause which genetics has rehabilitated in the new clothing of the « generic program ».

Error-related electroencephalographic signals have been widely studied concerning the human cognitive capability of differentiating between erroneous and correct actions. Midfrontal error-related negativity and theta band oscillations are believed to underlie post-action error monitoring. However, it remains elusive how early monitoring activity is trackable and what are the pre-response brain mechanisms related to performance monitoring. Moreover, it is still unclear how task-specific parameters, such as cognitive demand or motor control, influence these processes. Here, we aimed to test pre- and post-error EEG (...) patterns for different types of motor responses and investigate the neuronal mechanisms leading to erroneous actions. We implemented a go/no-go paradigm based on keypresses and saccades. Participants received an initial instruction about the direction of response to be given based on a facial cue and a subsequent one about the type of action to be performed based on an object cue. The paradigm was tested in 20 healthy volunteers combining EEG and eye tracking. We found significant differences in reaction time, number, and type of errors between the two actions. Saccadic responses reflected a higher number of premature responses and errors compared to the keypress ones. Nevertheless, both led to similar EEG patterns, supporting previous evidence for increased ERN amplitude and midfrontal theta power during error commission. Moreover, we found pre-error decreased theta activity independent of the type of action. Source analysis suggested different origin for such pre- and post-error neuronal patterns, matching the anterior insular cortex and the anterior cingulate cortex, respectively. This opposite pattern supports previous evidence of midfrontal theta not only as a neuronal marker of error commission but also as a predictor of action performance. Midfrontal theta, mostly associated with alert mechanisms triggering behavioral adjustments, also seems to reflect pre-response attentional mechanisms independently of the action to be performed. Our findings also add to the discussion regarding how salience network nodes interact during performance monitoring by suggesting that pre- and post-error patterns have different neuronal sources within this network.

Contributing to the recent debate on whether or not explanations ought to be differentiated from arguments, this article argues that the distinction matters to science education. I articulate the distinction in terms of explanations and arguments having to meet different standards of adequacy. Standards of explanatory adequacy are important because they correspond to what counts as a good explanation in a science classroom, whereas a focus on evidence-based argumentation can obscure such standards of what makes an explanation explanatory. I provide (...) further reasons for the relevance of not conflating explanations with arguments (and having standards of explanatory adequacy in view). First, what guides the adoption of the particular standards of explanatory adequacy that are relevant in a scientific case is the explanatory aim pursued in this context. Apart from explanatory aims being an important aspect of the nature of science, including explanatory aims in classroom instruction also promotes students seeing explanations as more than facts, and engages them in developing explanations as responses to interesting explanatory problems. Second, it is of relevance to science curricula that science aims at intervening in natural processes, not only for technological applications, but also as part of experimental discovery. Not any argument enables intervention in nature, as successful intervention specifically presupposes causal explanations. Students can fruitfully explore in the classroom how an explanatory account suggests different options for intervention. (shrink)

Arguably the most influential models of human decision-making today are based on the assumption that two separable systems – intuition and deliberation – underlie the judgments that people make. Our recent work is among the first to present neural evidence contrary to the predictions of these dual-systems accounts. We measured brain activations using functional magnetic resonance imaging (fMRI) while participants were specifically instructed to either intuitively or deliberately judge the authenticity of emotional facial expressions. Results from three different analyses revealed (...) both common brain networks of activation across decision mode and differential activations as a function of strategy adherence. We take our results to contradict popular dual-systems accounts that propose a clear-cut dichotomy of the processing systems, and to support rather a unified model. According to this, intuitive and deliberate judgment processes rely on the same rules, though only the former are thought to be characterized by non-conscious processing. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:53 HUME ON ARTIFICIAL LIVES with a Rejoinder to A.C. Maclntyre The variety of human cultures fascinated Enlightenment thinkers and evoked certain problems for philosophical discussion. Wide experience of other societies, as well as the study of history, disclosed moral systems interestingly different from modern European mores. Also a student of other cultures, historical and contemporary, David Hume is a moderate pluralist on the matter of alternative moral systems. (...) He acknowledges that there are systems of values other than that shared by his readers which qualify as moralities; but more interestingly, he also holds that there are some such systems which, despite the claims of their adherents, fail to qualify as moralities. Thus Hume opposes forms of relativism that allow any system which a community deems to be a moral code has to be acknowledged as constituting a genuine morality. In this paper I address the question of how Hume can discriminate among value systems and declare some to be moralities, some not. Given the design of his philosophical approach to morals, addressing this question is a matter of some importance for Hume, since he maintains that moral reflection takes its departure from everyday moral beliefs and sentiments. This being the case, we might expect that what should count as 'everyday moral beliefs and sentiments' would be whatsoever any individual or group puts forward as a morality, and that Hume's pluralism impedes him from raising a critical challenge to any system advanced, no matter how strange it might be. But Hume holds that certain systems advanced for the guidance of life which are sharply opposed to 54 everyday beliefs and sentiments do not constitute a morality, even if they number many as adherents. It is instructive to observe that A.C. Maclntyre believes that Hume's position is deeply flawed. He asserts that the treatment of rival tables of the virtues constitutes a most serious weakness in Hume's 2 theory of morals. Maclntyre contends that Hume's spurning of the monkish virtues, for instance, or his preference of Cicero's Offices over the Christian Whole Duty of Man, is devoid of theoretical justification and amounts to a matter of personal idiosyncrasy and eighteenth-century class elitism. Thus this seems a problem worthy of discussion. In what follows I shall: (a) lay out the problem of artificial lives as it arises in A Dialogue; (b) describe five points of differentiation between artificial lives and nonartificial lives; (c) review some less than fully satisfactory solutions to the problem; (d) introduce what I take to be the chief considerations supporting Hume's rejection of artificial lives; and finally (e) discuss whether Maclntyre 's objections to Hume's treatment of artificial lives are sustainable. 1. The Context of the Problem Hume deals with diversity of morals most expressly in A Dialogue, the short work appended to the second Enquiry. The essay records an exchange between one Palamedes, a lover of the novel and the striking, and his interlocutor, referred to merely as "I". Palamedes confounds the interlocutor by narrating a story about a distant people (the inhabitants of 'Fourli") whose mores include practices, apparently deemed moral by them, which sharply offend his, and presumably our, moral A sensibilities. Having elicited the interlocutor's 55 felt disapproval of those practices, Palamedes delights in revealing that the people of whom he has been speaking in cloaked terms are none other than the interlocutor's beloved Greeks of classical antiquity. Not satisfied with astonishing the interlocutor, he goes on to draw a strongly relativist conclusion about morals in general. The interlocutor confronts the choice of either abandoning his moral admiration of the civilization of the Greeks or of accepting some measure of the relativism in morals that Palamedes is advocating. The interlocutor does neither. He distinguishes between the principles of moral approbation or disapprobation and specific examples of approval or disapproval (E 333). He grants that there are examples of practices of which the ancients apparently approved and contrariwise we disapprove, but he denies that the existence of some such instances warrants the serious sort of relativism that Palamedes would foist on him. Obviously the number of such discrepancies cannot be overwhelming, otherwise the... (shrink)

Toleration is one possible response to diversity, and it is a defining feature of contemporary liberal democracies. Still, why we should tolerate and what we should tolerate are persistent political questions. This dissertation explores the reasons why citizens should sometimes refrain from embodying in law moral beliefs that they hold to be true. It claims that a neglected aspect of John Locke's writings on religious toleration, the formal relationship between moral principles and law, can instruct political deliberation. Since this portion (...) of Locke's thought is deeply influenced by Christian natural law, the approach is analogical. Locke confronted some political problems analogous to our own and there are alternative secular justifications available for the intermediate principles he employed. These intermediate principles can provide meaningful guidance in contemporary disputes about law and morality. ;Chapter Two explores Locke's most important insight into the formal relationship between law and morality, concerns about the use of "non-neutral principles" in political argument. A non-neutral principle is one that contains the very term under dispute between two contending parties. Neglected arguments in Locke's Third Letter Concerning Toleration provide formal tests for differentiating between non-neutral principles that do and do not justify coercive law. The Lockean criteria assume a "juridical equality" between persons such that at the persons who disagree are moral equals under a common set of public, general, and reasonable rules that determine when they may and may not use force. ;This Lockean insight has broad implications both for political theory and Locke scholarship. Chapter Three explores the relationship between natural law, consent, and the public good and argues that Lockean criteria can help modern readers choose between competing conceptions of the public good. Chapter Four explores the tensions between the Lockean formal criteria and Locke's specific views about which groups the government should tolerate. Chapter Five shows how a Lockean theory can account for institutional reasons for toleration, instances where a person refrains from putting a stop to an action for lack of jurisdiction. Chapter Six shows how both substantive and institutional forms of toleration should guide interpreters of the United States Constitution. (shrink)
