Flexible serial response learning by pigeons (Columba livia) and humans (Homo sapiens)

Experimental tasks designed to involve procedural memory are often rigid and unchanging, despite many reasons to expect that implicit learning processes can be flexible and support considerable variability. A version of the serial response time (SRT) task was developed, in which the locations of targets were probabilistically determined. Targets appeared in locations according to both a structured sequence and a cue validity parameter, and the time to respond to each target was measured. Pigeons (Columba livia) and humans (Homo sapiens) both showed response time facilitation at the highest tested value for cue validity, and the magnitude of that facilitation gradually weakened as cue validity was decreased. Both species showed evidence that response times were largely determined by the local predictabilities of individual cue locations. In addition, humans showed some evidence that explicit knowledge of the sequence affected response times, specifically when cue validity was 100%.     

Challenging Merton's Protestantism‐Science Hypothesis: The Historical Impact of Sacerdotal Celibacy on German Science and Scholarship

Denominational differences in the number of scientists produced in Germany during the period 1550 to 1900 are linked to the historical impact of Catholic celibate and Protestant noncelibate clergy households. Protestant leadership in science is largely attributable to the development of a new social mobility pattern among descendants of their clergy that enhanced the pastorate's ability to convey cultural and social capital to their marrying offspring, something denied to Catholic clergy. By reference to German historical developments, I show that the contributions of clerical households, far from being limited to the natural sciences, were equally in evidence across most other areas of scholarly endeavor. A discussion of the theoretical implications of these findings provides a comparative analysis of Protestant to Catholic scholarly achievements in general, and of scientific achievements in particular, as well as a critical assessment of Robert K. Merton's theorizing on the subject.     

Psychometric Properties and Administration Measurement Invariance of Social Phobia Symptom Measures: Paper-Pencil vs. Internet Administrations

The psychometric properties of the online versions of assessment instruments for phobias and related symptoms were compared to those of paper-pencil versions. The examined measures were the Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS). Students (n = 514) completed the instruments either in a paper-pencil in lab condition or an online at home condition. Means of the measures were largely equivalent between the two groups. Factor structures of the measures support construct validity of the two versions of the questionnaires. The coefficient alphas for the measures were reasonably high, ranging between .91 and .93 for both groups. Correlations between the measures were similar across groups. Overall, adequate psychometric properties of the online versions of the instruments were demonstrated, however, neither of the social phobia measures demonstrated measurement invariance between the two assessment modalities.     

Head-body ratio as a visual cue for stature in people and sculptural art

Body size is crucial for determining the outcome of competition for resources and mates. Many species use acoustic cues to measure caller body size. Vision is the pre-eminent sense for humans, but visual depth cues are of limited utility in judgments of absolute body size. The reliability of internal body proportion as a potential cue to stature was assessed with a large sample of anthropometric data, and the ratio of head height to body height (HBR) was found to be highly correlated with stature. A psychophysical experiment was carried out to investigate whether the cue actually influences stature judgments. Participants were shown pairs of photographs of human figures in which HBR had been manipulated systematically, and asked to select the figure that appeared taller. Results showed that figures with a relatively small HBR were consistently perceived as taller than figures with a relatively large HBR. Many classical statues such as Michelangelo's David depart from the classical proportions defined in Leonardo's Vitruvian Man. A supplementary experiment showed that perceived stature in classical statues also depends on HBR. Michelangelo's David was created with the HBR of a man 165 cm (5 ft 5 in) tall.     

“End-of-life” biases in moral evaluations of others

When evaluating the moral character of others, people show a strong bias to more heavily weigh behaviors at the end of an individual’s life, even if those behaviors arise in light of an overwhelmingly longer duration of contradictory behavior. Across four experiments, we find that this “end-of-life” bias uniquely applies to intentional changes in behavior that immediately precede death, and appears to result from the inference that the behavioral change reflects the emergence of the individual’s “true self”.     

Videotherapie bei postpartalen Störungen

Video recording is currently part of in- and out-patient therapy programs for parents with infants. The observation and analysis of video sequences allow the patient to gain an extraordinary insight with respect to its own experience and behaviour. Video Microanalytical Therapy (VMT) looks for the mother’s positive qualities in her relationship to the child and employs these qualities in order to support successful interactions. VMT is well-suited to the treatment of mothers with postpartal affective or psychotic disorders, because the typical cognitive distortions and reduced perception shown by these mothers can be avoided to a large extent through the use of pictures. In this study, a video microanalytical therapy concept will be presented, that was developed for the treatment of postpartally disordered mothers at the Psychiatric Centre Nordbaden in Wiesloch, Germany.     

Preventing Violence Against Women: Engaging the Fathers of Today and Tomorrow

Although fathers play a key role in helping their children develop ideas about gender relations and close relationships, they have been largely overlooked as a resource to help prevent violence against women. This paper explores some of the reasons why fathers have not been successfully engaged in violence prevention. Engaging fathers to promote wider definitions of masculinity for themselves and their children is presented as a major mechanism by which fathers could help prevent violence against women. The information-motivation-behavior model of change, developed for preventing high-risk sexual behavior, is applied to the area to provide structure for understanding previous and current attempts to engage fathers. Examples of innovative programs are used to highlight the application of this model.     

Defining Compulsive Behavior

Neuropsychology Review - Compulsive tendencies are a central feature of problematic human behavior and thereby are of great interest to the scientific and clinical community. However, no consensus...     

Theological Education as Missional Formation

Theological education is missional in nature. The disability perspective within theological education provides this missional aspect, which is vital for the growth and sustenance of the church. Since its inception, the World Council of Churches Ecumenical Disability Advocates Network (WCC‐EDAN) has contributed to this great mission. This paper is an attempt to understand theological education as missional formation from the perspective of disability studies, especially the contributions of WCC‐EDAN.
