Application testing of a new three-dimensional acceleration measuring system with wireless data transfer (WAS) for behavior analysis

A wireless acceleration measurement system was applied to free-moving cows and horses. Sensors were available as a collar and a flat box for measuring leg or trunk movements. Results were transmitted simultaneously by radio or stored in an 8-MB internal memory. As analytical procedures, frequency distributions with standard deviations, spectral analyses, and fractal analyses were applied. By means of the collar sensor, basic behavior patterns (standing, grazing, walking, ruminating, drinking, and hay uptake) could be identified in cows. Lameness could be detected in cows and horses by means of the leg sensor. The portion of basic and harmonic spectral components was reduced; the fractal dimension was reduced. The system can be used for the detection and analysis of even small movements of free-moving humans or animals over several hours. It is convenient for the analysis of basic behaviors, emotional reactions, or events causing flight or fright or for comparing different housing elements, such as floors or fences.     

Modulations of the processing of line discontinuities under selective attention conditions?

We examined whether the processing of discontinuities involved in figure-ground segmentation, like line ends, can be modulated under selective attention conditions. Subjects decided whether a gap in collinear or parallel lines was located to the right or left. Two stimuli were displayed in immediate succession. When the gaps were on the same side, reaction times (RTs) for the second stimulus increased when collinear lines followed parallel lines, or the reverse, but only when the two stimuli shared the same orientation and location. The effect did not depend on the global form of the stimuli or on the relative orientation of the gaps. A frame drawn around collinear elements affected the results, suggesting a crucial role of the "amodal" orthogonal lines produced when line ends are aligned. Including several gaps in the first stimulus also eliminated RT variations. By contrast, RT variations remained stable across several experimental blocks and were significant for interstimulus intervals from 50 to 600 msec between the two stimuli. These results are interpreted in terms of a modulation of the processing of line ends or the production of amodal lines, arising when attention is selectively drawn to a gap.     

Synergistic person x situation interaction in distributive justice behavior

A person x situation interaction is synergistic when a personality trait amplifies the effect of a situational factor. The present study tested how individuals' justice attitudes and situational factors jointly affect the allocation of financial burdens. Six insurance cases were described to 80 participants. Economic status of client (high, low) and responsibility of client for damage of the insured (high, low) were manipulated between subjects. Participants suggested a percentage of the total costs that they considered a fair contribution by the client. In accordance with the synergistic model, justice attitude (person factor) and responsibility for damage (situation factor) interacted and explained 5% of the variance of the dependent variable. With increasing negativity of attitude toward equality, the effect of responsibility was larger. Several cognitive mechanisms, such as motivated perception, selective attention, and the availability of attitude congruent situation schemas, that may account for synergistic interactions in justice behavior and in other domains were discussed.     

Religious Knowledge and Its Use in Psychiatry

Clinicians' knowledge of and sensitivity to religious issues have been questioned. The present study measures religious knowledge and willingness to utilize such knowledge in clinical practice. We administered a 41-item questionnaire testing religious knowledge and willingness to utilize such knowledge to 28 psychiatric clinicians. The mean religious knowledge score was 61% of the total possible score. In spite of low scores, only 33% of clinicians consistently refrained from initiating discussions of religious issues. Results support a low level of religious knowledge but do not support a contention that clinicians are insensitive to religious issues.     

On the Art of Finding Arguments: What Ancient and Modern Masters of Invention Have to Tell Us About the "Ars Inveniendi"

This paper deals with what has been called "ars inveniendi" (art of finding) in antiquity, medieval and early modern times. A survey of different techniques of finding tenable and relevant arguments is presented (among them, the Topical tradition, Status theory, Debate theory, Encyclopedic systems, Creativity techniques). Their advantages and disadvantages are critically compared. It is suggested that a mixture of strategies of finding arguments should be used. Finally, a few remarks showing the relationship beween the strategies of finding arguments and creativity in general are given.     

Classification of situations specific to field and behaviour: The context of aggressive interactions in schools

Based on a social psychological concept of aggression, in which the processes of definition and judgement of acts of behaviour are credited with central meaning, the situational context of aggressive interactions was systematized for a specific field (school). It is assumed that the particular circumstances of a situation provide information for the interpretation of a particular action, and that this interpretation varies depending on these circumstances. In the following study, norm deviation, intent and injury, are used as central criteria for judging on action as aggressive in order to establish a taxonomy of social situations, presented as verbal scenarios, that is both field-and behaviour-specific. 686 school children aged between 13 and 19 years participated in this study. By using a multivariate analysis procedure, groups of situations were identified in which similar judgements of a particular action emerged. Both typical judgement patterns and corresponding situation characteristics were used in the interpretation of the resulting situation taxonomy.     

Social-consensual conceptions concerning the progress of aggressive interactions

The present study investigated social consensual conceptions concerning the appropriateness relation between an initiative aggressive action and the reaction to it. To this end subjects were asked to choose between four configurations of mediatory information between B's initial act and A's reaction (i.e. ‘A's offence at B's behaviour’, ‘inappropriateness of B's behaviour’, ‘A's personal standards’, ‘A's fear of negative consequences’), so as to combine identical initial acts with incompatible reactions (i.e. ‘escalation’, ‘breaking’ of, and ‘compensation’) into meaningful episodes. The statistical procedure used, configural frequency analysis, shows that as compared with the number of theoretically possible configurations, very few were selected by subjects (with a high degree of unanimaty) as being specific to a particular type of reaction. Apparently subjects have definite and uniform conceptions about the appropriateness of incompatible reactions to certain aggressive actions in interpersonal conflicts.
