Effects of Backpack Carriage on Dual-Task Performance in Children During Standing and Walking

Primary school children perform parts of their everyday activities while carrying school supplies and being involved in attention-demanding situations. Twenty-eight children (8–10 years old) performed a 1-legged stance and a 10 m walking test under single- and dual-task situations in unloaded (i.e., no backpack) and loaded conditions (i.e., backpack with 20% of body mass). Results showed that load carriage did not significantly influence children's standing and walking performance (all p > .05), while divided attention affected all proxies of walking (all p < .001). Last, no significant load by attention interactions was detected. The single application of attentional but not load demand negatively affects children's walking performance. A combined application of both did not further deteriorate their gait behavior.     

Continuous Measurement of Breaks in Presence: Psychophysiology and Orienting Responses

Assessing presence using questionnaires can yield interesting insights into the user experience in virtual environments, but is also limited both in terms of reliability and validity. Breaks in presence (BIPs) are an interesting alternative, given that the researcher can assess them correctly. Prior studies on the psychophysiology of BIPs followed an exploratory approach by not providing a cognitive mechanism for BIPs and lacking in external validity. We argue that BIPs can be considered a special form of orienting responses involving both the real and the virtual world. In the first of the presented studies, we investigated which types of BIPs can be differentiated and to what degree they affect the user experience. In the second study, we modified a commercial video game by introducing the previously identified BIPs and recorded psychophysiological measurements. The results are in line with findings on orienting responses and should provide fertile ground for future research.     

Long Lives and Old Age Poverty: Social Stratification and Life-Course Institutionalization in Switzerland

This article combines an inter- and an intra-cohort perspective to study economic vulnerability in old age. The theoretical background is given through the combination of a social stratification framework and an institutional perspective emphasizing life course policies. At the macro level, the increase in overall education levels and the implementation of a pension system were the driving forces of the strong decrease in old age poverty over the last three decades. At an individual level, the pathway from low education early in life to economic hardship after retirement is most prominent, corresponding to a social stratification and cumulative disadvantage view.     

Die DPG-Praxis-Studie

All psychotherapeutic methods must be scientifically evaluated. Empirical evaluation of evidence is a prerequisite for acceptance as scientific psychotherapy as well as for payment by health insurance. Currently the psychotherapy methods accepted within the German health system (behavioural therapy, psychodynamic psychotherapy, and analytic psychotherapy) are reviewed by a governmental evaluation committee concerning evidence, necessity and cost-effectiveness. The DPG practice study has basically two aims: 1) to conduct a large naturalistic study to investigate effectiveness, sustainability and economic aspects of psychodynamic and analytic psychotherapy and 2) to offer a framework for psychoanalytic institutes, members, candidates or groups to realize own research ideas by collecting additional data within the study. The present article describes the background, main research questions, structure and design of the DPG practice study with regard to the evaluation questions.     

Facetten eines „deutschen“ Gegenübertragungsproblems

Departing from two case vignettes of psychoanalytic treatments of foreign children of parents who had collaborated with the Germans during the second world war, we are pondering whether there is a specific form of German counter transference defense, making it impossible to allow destructive narcissistic transference offers full of relish through the patients out of the fear that their activation in the analyst might end up in shame and horror as in the previous generations. The nearly complete renunciation to work analytically on the Nazi and Wartime could be described as a secret agreement of the protagonists, finding its justification in keeping out this delightful destruction. The consequences of this abandonment are the disability to establish a solid oedipal position and a regression to the anal world, being characteristic for both postwar German states including much of the analytic work.

Helping Behavior as a Subtle Measure of Discrimination Against Lesbians and Gay Men: German Data and a Comparison Across Countries1

To unobtrusively assess attitudes toward lesbians and gay men, the wrong‐number technique was used in a field experiment in Germany. The results are compared to studies using the same paradigm in Switzerland, Great Britain, and the United States. This approach gives a realistic picture of intercultural differences in social behavior against lesbians and gay men. Across studies, the results indicated that homosexuals are less likely to receive help than are heterosexuals. The variation of this effect between countries closely corresponded to the ranking of attitudes toward homosexuality assessed in survey studies. Contrary to survey studies, however, women showed only marginally less negative attitudes toward gay persons than men, when actual helping behavior was used as an attitude index.     

The cognitive and affective dimensions of moral conviction: implications for attitudinal and behavioral measures of interpersonal tolerance

The present studies investigate the role of both cognitive and affective dimensions of moral conviction in contributing to negative interpersonal responses. After demonstrating that the cognitive and affective dimensions of moral conviction are distinct constructs, the studies show that the cognitive dimension is sufficient to produce many forms of interpersonal intolerance. Simply believing an issue to be moral (i.e., objectively grounded, non-negotiable) results in greater intolerance for (Study 1), less sharing with (Study 2), and greater distancing from (Study 3) people with divergent attitudes. The emotional intensity with which beliefs are experienced is not alone explanatory. Nonetheless, it interacts with moral beliefs to produce the highest levels of interpersonal intolerance, distancing from dissimilar others, and context insensitivity. This interaction pattern between moral beliefs and affect was specific to emotional intensity and not other measures of attitude strength (Study 3).     

Genetic and environmental determinants of temperament: a comparative study based on Polish and German samples

This study of 1555 adult mono‐ and dizygotic twins reared together estimates the heritability of temperament traits in a Polish and a German sample. We test whether the etiology of temperament traits differs between the two cultures and between different temperament traits. We assessed temperament traits with the Formal Characteristics of Behaviour–Temperament Inventory (FCB‐TI), the Pavlovian Temperament Survey (PTS), the Revised Dimensions of Temperament Survey (DOTS‐R), and the Emotionality–Activity–Sociability Temperament Survey (EAS‐TS). Taking error of measurement into account, genetic sources of variance explained about 50% of the variance of temperament traits. We found neither reliable cultural differences nor robust differences in the etiology of the traits. However, the four questionnaires differed systematically with respect to the proportion of genetic and environmental influences on their scales. Copyright © 2002 John Wiley & Sons, Ltd.
