Eye vergence is susceptible to the hollow-face illusion

When an observer looks at a hollow mask of a face, a normal convex face is often perceived [the hollow-face illusion--Gregory 1973, in Illusion in Nature and Art (London: Duckworth) pp 49-96]. We show that in exploring an illusory face, the eyes converge at the illusory and not at the real distances of fixated targets like the tip of the nose. The 'vergence error' appears even though the resulting disparities of the two retinal images of the target provide feedback that would allow an immediate correction. It is presumably the success of recognising a familiar object (a face) which overrides the correction of convergence. This suggests that the brain strives for a congruency of eye vergence and distance perception.     

Islamic theology and theological engineering in the Nordic setting

The aim of this article is partly one of identifying and problematizing obstacles and realistic possibilities regarding the emergent field of Islamic theology in the context of Nordic universities, with special emphasis on Denmark. For the moment, a full-scale Danish Islamic theology programme designed for Muslims seems an almost herculean task for a variety of reasons, the most important of which will be identified and critically discussed. Currently, a small-scale programme is the most feasible option and, as such, it has recently been launched at the Faculty of Theology at the University of Copenhagen. The article closes with an excursus arguing that not only would Nordic Muslim communities benefit from the establishment of an Islamic theology programme at the university level, Christian university theology today would certainly also benefit if an Islamic theology study-module were to be added to the standard curriculum. In a multi-religious society, sound academic knowledge about Islam and its relationship with Christianity is indeed a desideratum for the contemporary Christian theology student.     

Intelligence as the efficiency of cue-driven retrieval from secondary memory

Complex-span (working-memory-capacity) tasks are among the most successful predictors of intelligence. One important contributor to this relationship is the ability to efficiently employ cues for the retrieval from secondary memory. Presumably, intelligent individuals can considerably restrict their memory search sets by using such cues and can thereby improve recall performance. We here test this assumption by experimentally manipulating the validity of retrieval cues. When memoranda are drawn from the same semantic category on two successive trials of a verbal complex-span task, the category is a very strong retrieval cue on its first occurrence (strong-cue trial) but loses some of its validity on its second occurrence (weak-cue trial). If intelligent individuals make better use of semantic categories as retrieval cues, their recall accuracy suffers more from this loss of cue validity. Accordingly, our results show that less variance in intelligence is explained by recall accuracy on weak-cue compared with strong-cue trials.     

The Elusive Notion of “Argument Quality”

We all seem to have a sense of what good and bad arguments are, and there is a long history—focusing on fallacies—of trying to provide objective standards that would allow a clear separation of good and bad arguments. This contribution discusses the limits of attempts to determine the quality of arguments. It begins with defining bad arguments as those that deviate from an established standard of good arguments. Since there are different conceptualizations of “argument”—as controversy, as debate, and as justification—and since arguments in each of these senses can be used for different purposes, a first problem is that we would need a large variety of standards for “good” arguments. After this, the contribution focuses in particular on proposals made in the literature on how to assess the quality of arguments in the sense of justification. It distinguishes three problems of assessment: How to determine (1) whether reasons are acceptable, (2) whether reasons are sufficient to justify the conclusion, and (3) how to identify arguments in real-world speech acts and texts? It is argued that limitations of argument assessment result from unavoidable relativism: The assessment of many—if not most—arguments depends on the epistemic situation of the evaluator.     

Contributions of pre-Fitts researchers to goal-directed aiming studies

The author aimed to review some of the early research on goal-directed aiming and reaching. R. S. Woodworth's (1899) well known, and often referenced, paper is only one of the research papers, prior to the revolutionary paper of P. M. Fitts ( 1954 ), which had a significant effect on knowledge of human movements. When Fitts' work was published, much of the previous work was forgotten, as the new paradigm paved the way for a better theoretical basis for the understanding of human movement and, in particular, movement times. There was research prior to Woodworth and between Woodworth and Fitts that has made a contribution to understanding of aimed movements. Woodworth gave results that can still be of use today and made a number of postulations about the way that movements are performed. His and other data are reanalyzed in light of modern models, taking regard of the limitations in those experiments.     

Psychoanalytisch begründete Ans?tze in der forensischen Psychiatrie und Psychotherapie

After many years where manualized mainly behaviour treatments dominated in forensic settings, psychodynamic therapies are gaining acceptance and are performed and evaluated more and more in forensic hospitals and in prisons. This encompasses individual, couple, family and group therapies. Individual and group analysts are starting to perform these tasks again, mostly as workers in forensic settings but also as external therapists and supervisors. All staff members are important in creating a therapeutic community based on group analytic principles. They are therefore required to build up a therapeutic attitude supported by regular external case and team supervision. Delictogenic situations occur in everyday life as well as in professional settings and are analysed mainly in group therapies, considering situations of the past and the effect on other people. Modern manualized analytical concepts, such as transference-focussed psychotherapy (TFP) and mentalization-based therapy (MBT) depthen the quality of therapeutic work of all professionals in forensic settings. The multimorbid and sometimes dangerous patients require good ethical and professional attitudes. The psychoanalytic concepts of defence and resistance, transference and countertransference are essential parts of changing internalization and corrective emotional experience, important parts of useful forensic treatments.     

Behavioral and physiological responses of young horses to different weaning protocols: a pilot study

In this study, effects of weaning on behavioral and physiological stress parameters in young horses (foals) were determined. Foals were weaned either simultaneously without the presence of adult horses (group A, n?=?6), or in the presence of two adult females familiar but unrelated to the foals (group B, n?=?5), or weaned consecutively by removing two mother horses per day (group C, n?=?6). Behavior, locomotion, salivary cortisol concentration, beat-to-beat (RR) interval, heart rate variability (HRV) and weight were determined. Group A foals lost weight for 2 days (mean?±?SEM) -?8.3?±?1.6?kg, p?相似文献
