The results of two experiments are analyzed to find out how artistic expertise influences visual search. Experiment I comprised survey data of 1,065 students on self-reported visual memory skills and their ability to find three targets in four images of artwork. Experiment II comprised eye movement data of 50 Visual Literacy experts and non-experts whose eye movements during visual search were analyzed for nine images of artwork as an external validation of the assessment tasks performed in Sample I. No time (...) constraint was set for completion of the visual search task. A latent profile analysis revealed four typical solution patterns for the students in Sample I, including a mainstream group, a group that completes easy images fast and difficult images slowly, a fast and erroneous group, and a slow working student group, depending on task completion time and on the probability of finding all three targets. Eidetic memory, performance in art education and visual imagination as self-reported visual skills have significant impact on latent class membership probability. We present a hidden Markov model approach to uncover underlying regions of attraction that result from visual search eye-movement behavior in Experiment II. VL experts and non-experts did not significantly differ in task time and number of targets found but they did differ in their visual search process: compared to non-experts, experts showed greater precision in fixating specific prime and target regions, assessed through hidden state fixation overlap. Exploratory analysis of HMMs revealed differences between experts and non-experts in image locations of attraction. Experts seem to focus their attention on smaller image parts whereas non-experts used wider parts of the image during their search. Differences between experts and non-experts depend on the relative saliency of targets embedded in images. HMMs can determine the effect of expertise on exploratory eye movements executed during visual search tasks. Further research on HMMs and art expertise is required to confirm exploratory results.

Differences in the ability of students to judge images can be assessed by analyzing the individual preference order of images. To gain insights into potential heterogeneity in judgement of visual abstraction among students, we combine Bradley–Terry preference modeling and model-based recursive partitioning. In an experiment a sample of 1,020 high-school students ranked five sets of images, three of which with respect to their level of visual abstraction. Additionally, 24 art experts and 25 novices were given the same task, while their (...) eye movements were recorded. Results show that time spent on the task, the students’ age, and self-reported interest in visual puzzles had significant influence on rankings. Fixation time of experts and novices revealed that both groups paid more attention to ambiguous images. The presented approach makes the underlying latent scale of visual judgments quantifiable.

Research on sustainability assurance is still in its beginnings. One of the key questions in this field that also is of the highest practical relevance is concerned with the quality of the assurance process. However, a common understanding of assurance quality and how it should be measured is still missing. We try to close this gap by building on the financial audit literature. We introduce a definition of assurance quality that comprises two key aspects: the depth of the assurance process (...) and the breadth of the assurance statement. Based on prior research, we hypothesize that a firm’s sustainability performance is related to the depth of the assurance process, while the type of the assurance provider, more precisely the affiliation to the accounting profession, is related to the breadth of the assurance statement. Results for a sample of 122 European firms reveal a negative relationship between sustainability performance and assurance process depth as well as between the affiliation to the accounting profession and assurance statement breadth. Thus, we find evidence that poor sustainability performers ask for in-depth assurance services, most likely as a means to enhance their internal sustainability-related processes and systems. Assurance providers that do not belong to the accounting profession in turn are associated with broader assurance statements. (shrink)

In view of the numerous accounting and corporate scandals associated with various forms of moral misconduct and the recent financial crisis, economics and business programs are often accused of actively contributing to the amoral decision making of their graduates. It is argued that theories and ideas taught at universities engender moral misbehavior among some managers, as these theories mainly focus on the primacy of profit-maximization and typically neglect the ethical and moral dimensions of decision making. To investigate this criticism, two (...) overlapping effects must be disentangled: the self-selection effect and the treatment effect. Drawing on the concept of moral judgment competence, we empirically examine this question with a sample of 1773 bachelor’s and 501 master’s students. Our results reveal that there is neither a self-selection nor a treatment effect for economics and business studies. Moreover, our results indicate that—regardless of the course of studies—university education in general does not seem to foster students’ moral development. (shrink)

How does the brain generate our experience of being in control over our actions and their effects? Here, we argue that the perception of events as self-caused emerges from a comparison between anticipated and actual action-effects: if the representation of an event that follows an action is activated before the action, the event is experienced as caused by one’s own action, whereas in the case of a mismatch it will be attributed to an external cause rather than to the self. (...) In a subliminal priming paradigm we show that participants overestimated how much control they had over objectively uncontrollable stimuli, which appeared after free- or forced-choice actions, when a masked prime activated a representation of the stimuli immediately before each action. This prime-induced control-illusion was independent from whether primes were consciously perceived. Results indicate that the conscious experience of control is modulated by unconscious anticipations of action-effects. (shrink)

While interdisciplinarity is not a new concept, the political and discursive mobilisation of interdisciplinarity is. Since the 1990s, this movement has intensified, and this has affected central funding bodies so that interdisciplinarity is now a de facto requirement in successful grant application. As a result, the literature is ripe with definitions, taxonomies, discussions and other attempts to grasp and define the concept of interdisciplinarity. In this paper, we explore how strategic demands for interdisciplinarity meet, interact with and change local research (...) practices and results of higher education and research. Our aim is to question and trace the consequences of applying the slippery and difficult term interdisciplinarity in research. The paper is based on ethnographic fieldwork in a Danish interdisciplinary research programme, where we observed and analysed practices of writing, publishing, collaboration and educational development in five different research projects. We show how the call for interdisciplinarity was mobilised in a way that rendered the incentives and motives behind the programme unclear. Furthermore, we argue that the absence of clear definitions and assessment criteria produced a dominant, all-inclusive, but vague, configuration of interdisciplinarity that affected the research outcome, and ultimately, promoted and reproduced the existing monodisciplinary research and power structures.

This study explores the attitude of German psychiatrists in leading positions towards joint crisis plans and psychiatric advance directives. This topic was examined by contacting 473 medical directors of German psychiatric hospitals and departments. They were asked to complete a questionnaire developed by us. That form contained questions about the incidence and acceptance of joint crisis plans and psychiatric advance directives and previous experiences with them. 108 medical directors of psychiatric hospitals and departments responded . Their answers demonstrate that in (...) their hospitals these documents are rarely used. Among the respondents, joint crisis plans are more accepted than psychiatric advance directives. There is a certain uncertainty when dealing with these instruments. Our main conclusion is that German psychiatry needs an intensified discussion on the use of instruments for patients to constitute procedures for future critical psychiatric events. For this purpose it will be helpful to collect more empirical data. Furthermore, the proposal of joint crisis plans in psychiatric hospitals and departments should be discussed as well as the possibility of consulting an expert during the preparation of a psychiatric advance directive.

It is widely believed that what distinguishes the social cognition of humans from that of other animals is the belief–desire psychology of four–year–old children and adults (so–called theory of mind). We argue here that this is actually the second ontogenetic step in uniquely human social cognition. The first step is one year old children's understanding of persons as intentional agents, which enables skills of cultural learning and shared intentionality. This initial step is ‘the real thing’ in the sense that it (...) enables young children to participate in cultural activities using shared, perspectival symbols with a conventional/normative/reflective dimension—for example, linguistic communication and pretend play—thus inaugurating children's understanding of things mental. Understanding beliefs and participating in collective intentionality at four years of age—enabling the comprehension of such things as money and marriage—results from several years of engagement with other persons in perspective–shifting and reflective discourse containing propositional attitude constructions.

This paper examines whether adults can adapt to novel accents of their native language that contain unfamiliar context-dependent phonological alternations. In two experiments, French participants listen to short stories read in accented speech. Their knowledge of the accents is then tested in a forced-choice identification task. In Experiment 1, two groups of listeners are exposed to newly created French accents in which certain vowels harmonize or disharmonize, respectively, to the rounding of the preceding vowel. Despite the cross-linguistic predominance of vowel (...) harmony over disharmony, the two groups adapt equally well to both accents, suggesting that this typological difference is not reflected in perceptual learning. Experiment 2 further explores the mechanism underlying this type of phonological learning. Participants are exposed to an accent in which some vowels harmonize and others disharmonize, yielding an increased featural complexity. They adapt less well to this regularity, showing that adaptation to novel accents involves feature-based inferences. (shrink)

This article focusses on the social and legal implications that blockchain technology brings about, not only due to its ideological framework, but also, and especially, due to the concept of law it inaugurates. Thus, this article claims, that, by interlocking technological and legal structures, blockchain technology initiates a profound displacement of legal symbolics and imaginaries. It shows how blockchain law, by emancipating itself from three essential dimensions of law—language, territory, and the body—implies a profound disruption of how we perceive law (...) and its legitimacy. Starting with an overview of the technological details of blockchain, the paper then addresses its ideological context and traces the underlying ideas, values and functions and their relation with—and impact on—the general perception of law and legal issues. By critically assessing the claim that blockchain will liberate the subject from any heteronymic constraints, this paper analyses to what extent this technology has social and legal implications that reach far beyond its virtual, purely blockchain-related scope of applications—and why this technology should matter to us all.

Texts and textures: approaching an age of human-made nature through the particulate, the volatile, and the radiant. We have entered the Anthropocene era—a geological age of our own making, in which what we have understood to be nature is made by man. We need a new way to understand the dynamics of a new epoch. These volumes offer writings that approach the Anthropocene through the perspectives of grain, vapor, and ray—the particulate, the volatile, and the radiant. The first three volumes—each (...) devoted to one of the three textures—offer a series of paired texts, with contemporary writers responding to historic writings. A fourth volume offers a guide to the project as a whole. Grain: Granular materials add up to concrete forms; insignificant specks accumulate into complex entities. The texts in this volume narrate some of the fundamental qualities of the granular. In one pairing of texts, Robert Smithson compares the accumulation of thoughts to the aggregation of sediment, and an environmental historian writes about the stakes for earthly knowledge today. Other authors include Alfred Russel Wallace, Denis Diderot, and Georges Bataille. Vapor: The vaporous represents matter's transformations. In this volume, a political scientist compares Kafka's haunting “Odradek” to “vibrant matter”; a media theorist responds to poems and diagrams by Buckminster Fuller; and more, including texts by Hippocrates, Italo Calvino, and James Clerk Maxwell. Ray: A ray is an act of propagation and diffusion, encompassing a chain of interdependencies between energy and matter. This volume includes texts by Spinoza (with a reconceptualization by a contemporary philosopher), Jacques Lacan (followed by an anthropologist's reflections on temporality), Thomas Pynchon (accompanied by an interpretation of Pynchon's “electro-mysticism”), and others. These volumes constitute a unique experiment in design and composition as well as content. The mingling of texts and the juxtaposition of different areas of knowledge represented in a variety of forms express the dynamics of a world in change. (shrink)

The subjective experience of time in depression has been described to be altered in complex ways, with sensations of particular slowness, delay or stillness being the most often named articulations. However, the attempts to provide empirical evidence to the phenomenon of “time slowing down in depression” have resulted in inconsistent findings. In consequence, the overall claim that depressive time somehow differs from ordinary time has often been discarded as unfounded. The article argues against such conclusion, contending that the described ambiguity (...) might be caused by the methods employed to assess the phenomenon under observation. In the first part of the article, a reconceptualization of the experience of time in depression is proposed on the grounds of classic and contemporary phenomenological psychiatry. This leads to identify the essential features of depressive time as described both in clinical and philosophical contexts. In the second part, a critique of the existing methods of time perception assessment is conducted, with a specific focus on duration estimation and time passage perception tasks. The above-mentioned core features serve as guidelines in discussing to what degree such methods fit the phenomenon at stake. Finally, an alternative and innovative method is put forward, that might not only help to explore the scope of existing methods but might itself present an alternative to such: the micro-phenomenological interview.

When do children acquire a propositional attitude folk psychology or theory of mind? The orthodox answer to this central question of developmental ToM research had long been that around age 4 children begin to apply “belief” and other propositional attitude concepts. This orthodoxy has recently come under serious attack, though, from two sides: Scoffers complain that it over-estimates children’s early competence and claim that a proper understanding of propositional attitudes emerges only much later. Boosters criticize the orthodoxy for underestimating early (...) competence and claim that even infants ascribe beliefs. In this paper, the orthodoxy is defended on empirical grounds against these two kinds of attacks. On the basis of new evidence, not only can the two attacks safely be countered, but the orthodox claim can actually be strengthened, corroborated and refined: what emerges around age 4 is an explicit, unified, flexibly conceptual capacity to ascribe propositional attitudes. This unified conceptual capacity contrasts with the less sophisticated, less unified implicit forms of tracking simpler mental states present in ontogeny long before. This refined version of the orthodoxy can thus most plausibly be spelled out in some form of 2-systems-account of theory of mind. (shrink)

When it comes to improving the health of the general population, mHealth technologies with self-monitoring and intervention components hold a lot of promise. We argue, however, that due to various factors such as access, targeting, personal resources or incentives, self-monitoring applications run the risk of increasing health inequalities, thereby creating a problem of social justice. We review empirical evidence for “intervention-generated” inequalities, present arguments that self-monitoring applications are still morally acceptable, and develop approaches to avoid the promotion of health inequalities (...) through self-monitoring applications.

We provide a detailed description of an interleaved and heavily annotated copy of Florae Berolinensis Prodromus, a flora of Berlin published by the German apothecary and botanist Karl Ludwig Willdenow in 1787, which today is preserved at the Staatsbibliothek zu Berlin – Preußischer Kulturbesitz. We demonstrate that this is the copy that the author himself used and carried with him during his botanical excursions in and around Berlin to prepare a second edition of the work. By analyzing this document as (...) paper technology, we reveal that even seemingly trifling aspects of its material organization enabled far-reaching biological research agendas that were not originally intended. The hybrid form of manuscript and printed book, used in field excursions, enabled a kind of natural-historical observation that was at once detailed and bound by strict convention, a combination that inadvertently opened new research questions and suggested new objects of research. We thereby contribute to an understanding of the history of natural history that goes beyond the history of ideas and the intended uses of techniques, giving an example of how routine work on paper within a scientific tradition could generate innovation.

In this paper an approach to the exhaustive interpretation of answers is developed. It builds on a proposal brought forward by Groenendijk and Stokhof (1984). We will use the close connection between their approach and McCarthy's (1980, 1986) predicate circumscription and describe exhaustive interpretation as an instance of interpretation in minimal models, well-known from work on counterfactuals (see for instance Lewis (1973)). It is shown that by combining this approach with independent developments in semantics/pragmatics one can overcome certain limitations of (...) Groenenedijk and Stokhof's (1984) proposal.

We investigated the impact of attention during encoding on later retrieval. During study, participants read some words aloud and named the print color of other words aloud . Then one of two memory tests was administered. The explicit test—recognition—required conscious recollection of whether a word was studied. Previously read words were recognized more accurately than were previously color named words. This contrasted sharply with performance on the implicit test—repetition priming in lexical decision. Here, words that were color named during study (...) showed priming equivalent to words that were read during study; both were responded to faster than unstudied words. Thus, an attentional manipulation during study had a strong effect on an explicit test of memory, but almost no effect on an implicit test. Focal attention during study is crucial for remembering consciously but not necessarily for remembering without awareness. (shrink)

Overweight and obesity among children and adolescents are global problems of our time. Due to their authority and role modeling, parents play an essential part in the efficacy of prevention and intervention programs. This study assessed the barriers that parents of overweight/obese children face in preventive and interventional health care utilization. Sixteen parents were qualitatively interviewed. A content analysis was performed, and barriers to change were allocated to their stage of change according to the transtheoretical model. Among the main barriers (...) is the underestimation of health risks caused by overweight/obesity in association with diminished problem awareness. Parents seem not necessarily in need of theoretical knowledge for prevention and interventions. They do however need support in evaluating the weight status of their child and the knowledge of whom to turn to for help as well as specific and hands-on possibilities for change. The results extend past studies by adding specific barriers to change that parents commonly experience. Possibilities to address these barriers, e.g., through trainings at the pediatric practice or adoption of conversation techniques, are discussed. Future studies might identify subgroups experiencing specific barriers and thus be able to address these in an individualized way. (shrink)

Children develop language and communication skills through interaction with adults and other children. This study therefore focuses on two interdependent issues: the effect of philosophizing with children on children’s language development and the speech acts of teachers and children in philosophical enquiries. As part of a before-after test with the “Hamburger Verfahren zur Analyse des Sprachstandes Fünfjähriger”, weekly philosophical discussions were undertaken with a test class over a period of six months. The central findings are that the philosophising children developed (...) significantly higher language ability compared with a non-philosophising control class in two areas, namely general performance in discussion and the use of more sophisticated connectors. A further part of the study compared the speech acts of the children and their pre-school teacher in the context of philosophical discussion with their speech acts in a different dialogic situation. This showed that philosophical questions from the pre-school teacher led to the production of particularly complex language by the children. Complex speech acts involve the use of higher-level verb structures and connectors. These are necessary in order to reason and act as a citizen agent and are supported by philosophising with children, as this study shows. (shrink)

El presente artículo demuestra que el anhelo por el más allá que había expresado Juan Larrea en su poesía llega a su culminación en Diario del Nuevo Mundo. La experiencia vivida en el exilio mexicano le impulsa a abandonar el yo subjetivo y dejarse absorber por una conciencia objetiva que viene a constituir el epicentro de su proyecto filosófico. De esta manera, Larrea funda en Diario del Nuevo Mundo los principios constitutivos de una filosofía transcendental a la vez que describe (...) la situación personal en la que se encuentra. Además, el artículo mantiene que Larrea es de los más radicales entre los pensadores exiliados en su crítica de la racionalidad tecno-científica y que el proyecto de Larrea solo es posible porque se apoya en disciplinas tradicionalmente marginalizadas dentro de la filosofía como son la psicología, la religión y la poesía.

Die Diatriben und das Encheiridion des Stoikers Epiktet (spätes 1. bis frühes 2.Jh.n.Chr.) erfreuen sich eines bleibenden Interesses in der Forschung. Dies belegen zahlreiche Einzeluntersuchungen sowie neuere Kommentare und Übersetzungen zu ausgewählten Kapiteln seines Werkes. Als Stoiker weist Epiktet insofern eine Besonderheit auf, als er die theologischen Aspekte in seiner Philosophie besonders betont. Die vorliegende Arbeit beschäftigt sich mit einem wichtigen Teil der Theologie Epiktets: seiner Gebetslehre. Epiktet integriert in sein Werk Gebetstexte, die er seinen Schülern als Vorbild- und Übungstexte (...) an die Hand gibt, und stellt mehrfach die Wichtigkeit der Gebete innerhalb des täglichen Lebens heraus. Sie sind nach Epiktets Lehre ein zentrales Element der angemessenen stoischen Lebenshaltung. Mit seiner Gebetslehre beeinflusst Epiktet nicht nur Philosophen der Antike, sondern auch frühchristliche Theologen. Um Epiktets Gebetslehre vorzustellen, werden die Gebete Epiktets und seine Aussagen über das Beten in der vorliegenden Arbeit in ihrem jeweiligen Kontext bezüglich Form, Inhalt und Funktionen analysiert und interpretiert. Darüber hinaus wird anhand der Gebetslehren ausgewählter Autoren ein Einblick in die Geschichte des philosophischen Gebets gegeben, um Epiktets Gebetslehre anschließend darin verorten zu können.

A shift towards a bioeconomy is not sustainable per se. In order to contribute to sustainable development, a bioeconomy must meet certain conditions. These conditions have been discussed with respect to technology and also to the importance of ethical aspects. Consumers’ behavior has also been acknowledged. However, consumers still have to choose sustainable consumption options, and this choice depends on their psychological makeup, which can be related to two factors: behavioral costs and individual sustainability motivation. Behavioral costs determine how difficult (...) the consumption of a bio-based product is, relative to other less sustainable consumption options. Sustainability motivation determines how much effort a person is willing to expend for a more sustainable consumption option, for the sustainable use and recycling of a product, or even to refrain from engaging in consumption. In addition, in a complex bioeconomic system, the sustainability of a bio-based consumption option is not always clear cut. After providing an introduction to the systemic and technological background of bio-based products, we present how consumers’ sustainability motivation is an essential and decisive pull factor for a circular sustainable bioeconomy. We also present the drivers of consumers’ sustainability motivation as necessary components of a sustainable bioeconomic system. (shrink)

Abstract: Focusing on early child pretend play from the perspective of developmental psychology, this article puts forward and presents evidence for two claims. First, such play constitutes an area of remarkable individual intentionality of second-order intentionality (or 'theory of mind'): in pretence with others, young children grasp the basic intentional structure of pretending as a non-serious fictional form of action. Second, early social pretend play embodies shared or collective we-intentionality. Pretending with others is one of the ontogenetically primary instances of (...) truly cooperative actions. And it is a, perhaps the, primordial form of cooperative action with rudimentary rule-governed, institutional structure: in joint pretence games, children are aware that objects collectively get assigned fictional status, 'count as' something, and that this creates a normative space of warranted moves in the game. Developmentally, pretend play might even be a cradle for institutional phenomena more generally. (shrink)

In order for artificial intelligent systems to interact naturally with human users, they need to be able to learn from human instructions when actions should be imitated. Human tutoring will typically consist of action demonstrations accompanied by speech. In the following, the characteristics of human tutoring during action demonstration will be examined. A special focus will be put on the distinction between two kinds of motion events: path-oriented actions and manner-oriented actions. Such a distinction is inspired by the literature pertaining (...) to cognitive linguistics, which indicates that the human conceptual system can distinguish these two distinct types of motion. These two kinds of actions are described in language by more path-oriented or more manner-oriented utterances. In path-oriented utterances, the source, trajectory, or goal is emphasized, whereas in manner-oriented utterances the medium, velocity, or means of motion are highlighted. We examined a video corpus of adult–child interactions comprised of three age groups of children—pre-lexical, early lexical, and lexical—and two different tasks, one emphasizing manner more strongly and one emphasizing path more strongly. We analyzed the language and motion of the caregiver and the gazing behavior of the child to highlight the differences between the tutoring and the acquisition of the manner and path concepts. The results suggest that age is an important factor in the development of these action categories. The analysis of this corpus has also been exploited to develop an intelligent robotic behavior—the tutoring spotter system—able to emulate children's behaviors in a tutoring situation, with the aim of evoking in human subjects a natural and effective behavior in teaching to a robot. The findings related to the development of manner and path concepts have been used to implement new effective feedback strategies in the tutoring spotter system, which should provide improvements in human–robot interaction.
