Understanding risk factors for relationship dissolution and poor relationship adjustment among couples has been an active area of research in relationship science. One risk factor, non-marital cohabitation, has shown to predict higher rates of relationship dissolution and relationship instability in some samples, but the associations among German parents with children over time are less clear. In this study, we examined the links between non-marital cohabitation and 10-year outcomes in 220 German families with preschool-aged children at the initial assessment followed into (...) adolescence. Families were assessed 7 times over the 10 years and retention at the 10-year follow-up was over 92%. After accounting for multiple testing, only mother’s report of better initial interparental communication predicted whether parents were likely to stay together over the course of the 10 years. Adolescents of parents who cohabited were at higher risk for externalizing symptoms 10 years later compared to children of married parents. In addition, although there were no differences between cohabiting couples and married couples at the initial assessment in relationship adjustment, cohabiting mothers who stayed with their partner over the 10 years showed significantly greater declines in relationship adjustment over the 10 years compared to married mothers. Findings indicate the need for further research that explores family structure and dynamics over time to inform refinement of prevention programs targeting relationships and children’s mental health.

Background Following passage of the Patient Self Determination Act in 1990, health care institutions that receive Medicare and Medicaid funding are required to inform patients of their right to make their health care preferences known through execution of a living will and/or to appoint a surrogate-decision maker. We evaluated the impact of external factors and perceived patient preferences on physicians’ decisions to honor or forgo previously established advance directives (ADs). In addition, physician views regarding legal risk, patients’ ability to comprehend (...) complexities involved with their care, and impact of medical costs related to end-of-life care decisions were explored. Methods Attendees of two Mayo Clinic continuing medical education courses were surveyed. Three scenarios based in part on previously court-litigated matters assessed impact of external factors and perceived patient preferences on physician compliance with patient-articulated wishes regarding resuscitation. General questions measured respondents’ perception of legal risk, concerns over patient knowledge of idiosyncrasies involved with their care, and impact medical costs may have on compliance with patient preferences. Responses indicating strength of agreement or disagreement with statements were treated as ordinal data and analyzed using the Cochran Armitage trend test. Results Three hundred eighty-eight of 951 surveys were completed (41% response rate). Eighty percent reported they were likely to honor a patient’s AD despite its 5 year age. Fewer than half (41%) would honor the AD of a patient in ventricular fibrillation who had expressed a desire to “pass away in peace.” Few (17%) would forgo an AD following a family’s request for continued resuscitative treatment. A majority (52%) considered risk of liability to be lower when maintaining someone alive against their wishes than mistakenly failing to provide resuscitative efforts. A large percentage (74%) disagreed that patients could not appreciate complexities surrounding their care while 69% agreed that costs should never impact a physician’s decision as to whether to comply with a patient’s AD. Conclusions Our findings highlight the impact, albeit small, external factors have on physician AD compliance. Most respondents based their decision on the clinical situation at hand and interpretation of the patient’s initial wishes and preferences expressed by the AD. (shrink)

One problem of interpreting research on subconscious processing is the possibility that participants are weakly conscious of the stimuli. Here, we compared the fMRI BOLD response in healthy adults to clearly visible single letters with the response to letters presented in the absence of any behavioural evidence of visibility . No letter catch trials served as a control condition. Forced-choice responses did not differ from chance when letter-to-background contrast was low, whereas they were almost 100% correct when contrast was high. (...) A comparison of fMRI BOLD signals for supraliminal and subliminal letters with the control trials revealed a signal increase in left BA 37 . Comparison of supraliminal with subliminal letters showed a significant increase in the right inferior frontal gyrus . Finally, a comparison of subliminal with supraliminal letters showed increases in the left middle temporal gyrus and the right extrastriate cortex. (shrink)

The behavioral sciences have come under attack for writings and speech that affront sensitivities. At such times, academic freedom and tenure are invoked to forestall efforts to censure and terminate jobs. We review the history and controversy surrounding academic freedom and tenure, and explore their meaning across different fields, at different institutions, and at different ranks. In a multifactoral experimental survey, 1,004 randomly selected faculty members from top-ranked institutions were asked how colleagues would typically respond when confronted with dilemmas concerning (...) teaching, research, and wrong-doing. Full professors were perceived as being more likely to insist on having the academic freedom to teach unpopular courses, research controversial topics, and whistle-blow wrong-doing than were lower-ranked professors (even associate professors with tenure). Everyone thought that others were more likely to exercise academic freedom than they themselves were, and that promotion to full professor was a better predictor of who would exercise academic freedom than was the awarding of tenure. Few differences emerged related either to gender or type of institution, and behavioral scientists' beliefs were similar to scholars from other fields. In addition, no support was found for glib celebrations of tenure's sanctification of broadly defined academic freedoms. These findings challenge the assumption that tenure can be justified on the basis of fostering academic freedom, suggesting the need for a re-examination of the philosophical foundation and practical implications of tenure in today's academy.

Capacities for abstract thinking and problem‐solving are central to human cognition. Processes of abstraction allow the transfer of experiences and knowledge between contexts helping us make informed decisions in new or changing contexts. While we are often inclined to relate such reasoning capacities to individual minds and brains, they may in fact be contingent on human‐specific modes of collaboration, dialogue, and shared attention. In an experimental study, we test the hypothesis that social interaction enhances cognitive processes of rule‐induction, which in (...) turn improves problem‐solving performance. Through three sessions of increasing complexity, individuals and groups were presented with a problem‐solving task requiring them to categorize a set of visual stimuli. To assess the character of participants’ problem representations, after each training session, they were presented with a transfer task involving stimuli that differed in appearance, but shared relations among features with the training set. Besides, we compared participants’ categorization behaviors to simulated agents relying on exemplar learning. We found that groups performed superior to individuals and agents in the training sessions and were more likely to correctly generalize their observations in the transfer phase, especially in the high complexity session, suggesting that groups more effectively induced underlying categorization rules from the stimuli than individuals and agents. Crucially, variation in performance among groups was predicted by semantic diversity in members’ dialogical contributions, suggesting a link between social interaction, cognitive diversity, and abstraction.

Background Regarding controversial medical services, many have argued that if physicians cannot in good conscience provide a legal medical intervention for which a patient is a candidate, they should refer the requesting patient to an accommodating provider. This study examines what US physicians think a doctor is obligated to do when the doctor thinks it would be immoral to provide a referral. Method The authors conducted a cross-sectional survey of a random sample of 2000 US physicians from all specialties. The (...) primary criterion variable was agreement that physicians have a professional obligation to refer patients for all legal medical services for which the patients are candidates, even if the physician believes that such a referral is immoral. Results Of 1895 eligible physicians, 1032 (55%) responded. 57% of physicians agreed that doctors must refer patients regardless of whether or not the doctor believes the referral itself is immoral. Holding this opinion was independently associated with being more theologically pluralistic, describing oneself as sociopolitically liberal, and indicating that respect for patient autonomy is the most important bioethical principle in one's practice (multivariable ORs, 1.6–2.4). Conclusions Physicians are divided about a professional obligation to refer when the physician believes that referral itself is immoral. These data suggest there is no uncontroversial way to resolve conflicts posed when patients request interventions that their physicians cannot in good conscience provide. (shrink)

Mueller et al. discuss the role of acoustic cues in detecting language structure more generally. Across languages, there are clear links between acoustic cues and syntactic structure. They show that AGL experiments implementing analogous links demonstrate that prosodic cues, as well as various auditory biases, facilitate the learning of structural rules. Some of these biases, e.g. for auditory grouping, are also present in other species.

Machiavellianism is a popular construct in research on ethics and organizational behavior. This research has demonstrated that Machiavellianism predicts a host of counterproductive, deviant, and unethical behaviors. However, individuals high in Machiavellianism also adapt to their organizational surroundings, engaging in unethical behavior only in certain situations. Nevertheless, the utility of Machiavellianism has been questioned. Meta-analyses have demonstrated that psychopathy out-predicts Machiavellianism for most antisocial outcomes. Thus, many researchers assume Machiavellianism is a derivative and redundant construct. However, researchers examining the utility (...) of Machiavellianism may be asking the wrong question about how Machiavellianism is unique. In our review, we find it less informative to ask about what antisocial behaviors Machiavellianism predicts. Instead, we find it more informative to ask when Machiavellianism predicts antisocial behaviors. Drawing on Field Theory and Trait Activation Theory, we argue that Machiavellianism is a trait that is associated with person × environment interactions. Their adaptive nature is made possible through the presence of impulse control and environmental sensitivity to punishment, two characteristics that individuals high in psychopathy lack. Consequently, individuals high in Machiavellianism constrain their antisocial behavior to environments when the benefits outweigh the costs. Thus, environmental context, especially the risk of external punishment, moderates Machiavellian misbehavior more than it does for those high in psychopathy. These behavioral constraints align with Lewin’s argument that behavior is a function of the person, environment, and interaction between the two. From this discussion, we arrive at recommendations pertaining to the future of Machiavellianism research in organizational and other applied settings. (shrink)

Research on the cognitive abilities involved in decision making has shown that, under objective risk conditions (i.e., when explicit information about possible outcomes and risks is available), superior decisions are especially predicted by executive functions and exact number processing skills, also referred to as objective numeracy. So far, decision-making research has mainly focused on exact number processing skills, such as performing calculations or transformations of symbolic numbers. There is evidence that such exact numeric skills are based on approximate number processing (...) (ANP) skills, which enable quick and accurate processing of non-symbolic numbers (e.g. Chen and Li, 2014). Very few studies, however, have investigated ANP skills in the context of risky decision making and have analyzed direct associations among the aforementioned sub functions. Possible interactions between the closely related skills have not been considered. The current study (N = 128) examines interactions of ANP skills with executive functions and objective numeracy, in predicting risky choice behavior. ANP skills are represented by the accuracy in a dot-comparison task. Decision making is measured by two versions of the Game of Dice Task (GDT), which place different emphases on the reflection of potential risks. The results show two-way as well as three-way interactions between the measures of ANP skills, executive functions, and objective numeracy in predicting risky decisions in both GDT versions. The riskiest decisions were most frequently made in case of low scores in all of the three competencies, while good performance in any one of them resulted in significant reductions of disadvantageous decisions. The findings indicate that high ANP skills can positively affect choice behavior in individuals who have weaknesses in reflectively attributed skills, namely executive functions and objective numeracy. Potential compensatory effects and mechanisms of ANP in decision making are discussed. (shrink)

The growth of high-stakes testing in state accountability systems necessitates further examination of their impact on stakeholders. Prompted by broader state-level reform in Kentucky, this evaluation aims to provide insight into a new accountability system's effect on social studies teachers. Using a goal-free evaluation model and case study design, the researchers examined the content and instructional decisions made by a group of U.S. history teachers in response to a new end-of-course exam designed by ACT-QualityCore. The evaluation incorporated a content analysis (...) of teacher materials, observation of a professional learning community meeting, and teacher interviews. The results of this evaluation indicate that teachers generally support the changes in the new assessment system but find specific elements frustrating and hesitate to completely revamp their instructional practices. Considering these assessment system changes occurred to advance Kentucky's goal of college and career readiness for all, this evaluation provides insight into what is actually happening in classrooms and should assist teachers and administrators as they assess the impact of these reforms on classroom practice.

Nurses play a crucial role in reducing health disparities and advancing health equity for individuals and communities. The future nursing workforce relies on their nursing education to prepare them to promote health equity. Nursing educators prepare students through a variety of andragogical learning strategies in the classroom and in clinical experiences and by intentionally updating and revising curricular content to address knowledge and competency gaps. This critical review aimed to determine the extent to which health equity concepts are explicitly present (...) in prelicensure undergraduate nursing curricula globally. Of 434 articles screened, 22 articles describing 20 studies met inclusion criteria. Frequency and quantity of health equity content, concepts and topics, teaching strategies, evaluation strategies, and the overall extent of integration varied widely. Notably, only two articles described overall well‐integrated explicit health equity content, and there was little attention to whether students transfer this learning into practice. A focus on individualism rather than population and community was noted, highlighting the presence of whiteness in nursing. Results from this review confirm that nursing education has room to improve with respect to health equity in the curricula. (shrink)

In our target article, we took the position that tenure conveys many important benefits but that its original justification – fostering academic freedom – is not one of them. Here we respond to various criticisms of our study as well as to proposals to remedy the current state of affairs. Undoubtedly, more research is needed to confirm and extend our findings, but the most reasonable conclusion remains the one we offered – that the original rationale for tenure is poorly served (...) by the current system as practiced at top-ranked colleges and universities.

O objetivo deste artigo é, primeiro, apresentar e considerar as críticas de Paley com mais detalhes e, em seguida, discutir algumas das aplicações significativas da fenomenologia que muitas vezes foram negligenciadas pelos pesquisadores qualitativos. Como foi amplamente demonstrado ao longo dos anos, a fenomenologia pode não apenas fazer a diferença no manuseio, análise e interpretação dos dados disponíveis, mas também em como os dados são obtidos em primeiro lugar, por exemplo, através de técnicas especiais de entrevista. Consideraremos algumas figuras centrais (...) da psicologia fenomenológica clássica e da psiquiatria fenomenológica e apresentaremos alguns dos desenvolvimentos mais recentes na ciência cognitiva. Em seguida, discutiremos três casos concretos que demonstram como a fenomenologia foi aplicada no trabalho clínico com pacientes com esquizofrenia, paralisia cerebral e negligência hemispatial.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

Programming computers to construct "real types," generally descriptive of a class of societies, makes explicit all steps in the thought process of such constructions because unambiguous instructions to, the computer are needed. The historian uses his judgment to choose a data field and variables that may be relevant in forming a type. He then looks for matches; he divides the data field into groups according to one variable and sees if the other variables differ significantly according to these groups. In (...) this process, he may discover new variables of importance. The selection of interesting types from among the matches can be determined only by the pragmatic interest of the historian; analysis of this selection process involves some of the most difficult problems in the study of historical technique. The computer using a "real type" program may be useful as a quick means to scan data. (shrink)

First published in 1954, and most recently reprinted in 2010, the self-stated aim of James’ book is to establish improved race relations in the world by revealing an underlying truth concerning the contribution of the African continent to the rest of the world. It is an attempt to show that the true authors of Greek philosophy were not the Greeks, but the Egyptians. This theft of the African philosophical legacy by the Greeks has led to the mistaken opinion that the (...) African continent has made no intellectual contribution to civilization – a misrepresentation that has become the root of racial prejudice. By bringing this information to the attention of the world, James hopes to remedy these prejudices which have corrupted human relations. (shrink)
