TY - JOUR A1 - Kahlert, Daniela A1 - Brand, Ralf T1 - Questionnaires for assessing physical activity different response scale categories influence responses concerning health- and sport-related cognitions JF - Zeitschrift für Gesundheitspsychologie N2 - The present study examines whether the use of different frequency scales in questionnaires about physical activity influences respondents' own estimation of their activity, as well as subsequent measurements of health- und sport-related cognitions and evaluations. Using a randomized research design we recruited a sample of 118 participants. One group received a high frequency scale for assessing their exercise frequency with the response categories "never", "less often", "once a month", "once a week", or "most days." The other group answered with a medium frequency scale with the alternatives "never", "less often", " once every few months", "once a month", and " once a week or more often." As dependent variables all participants judged the subjective importance of physical activity and their health-related quality of life (WHO-QOL-bref). Results indicate the expected response errors, owing to the fact that using a high-frequency scale produces higher levels of self-reported physical activity (Cramer's V = .30). Corresponding to this the subjective importance of physical activity increased (d = .37) and the health-related quality of life was judged to be better (d = .36). Such artefacts might be eliminated by using standardized formulations such as "I exercise... times per week/month for... minutes."

Risk factors included sex after only a short acquaintanceship, alcohol and drug use in sexual interactions, and ambiguous communication of sexual intentions. In addition to a measure of overall pornography use, exposure to portrayals of consensual sex, coerced sex and degrading sex was measured. Almost all participants had seen pornografic material at least once, just under half had seen depictions of coerced sex. Significant correlations were found between all measures of pornography use and the presence of risk factors of sexual aggression in consensual sexual scripts. Violent pornography usage showed a positive correlation with the normative acceptance of sexual aggression that was partly accounted for by sexual scripts. The findings are discussed with regard to the significance of pornografic media contents in the process of adolescents' sexual socialization.

Point-light actors (PLAs) representing common human motions were shown embedded in a visual noise reminiscent of "TV snow". At first, the PLAs were perceived clearly, then occluded from view for a short duration, during which it was hypothesized that a real-time action simulation was generated tracking the motion's course. The PLA then reappeared in motion at variable visibility against the noise, whilst detection thresholds for the reappearance were measured. In the crucial manipulation, the test motion was either temporally congruent with the motion as it would have continued during occlusion, and thus temporally matching the simulation, or temporally incongruent. Detection thresholds were lower for congruent than for incongruent reappearing motions, suggesting that reappearing motion that temporally matched the internal action simulation was more likely to be detected.

These values include well known variables such as printed frequency of word form and lemma as documented also in CELEX (Baayen, Piepenbrock und Gulikers, 1995). In addition, we compute new values like frequencies based on syllables, and morphemes as well as frequencies of character chains, and multiple word combinations. The statistics are based on the Kernkorpus des Digitalen Wrterbuchs der deutschen Sprache (DWDS) with over 100 million running words. We illustrate the validity of these norms with new results about fixation durations in sentence reading.

The data were obtained from a sample of 39 German teachers and their classes in the context of the Berlin Longitudinal Reading Study. Judgements on different levels were analysed (achievement of sixth graders in general and of individual students). Diagnostic skills were investigated using different indicators: the personal judgement error and tendency and the accuracy in identifying achievement differences between individual students (rank component). The accuracy in estimating reading capacities of students with and without a different language background was investigated by means of achievement level matched pairs. The outcomes indicated, among others, an overestimation of students' general achievement level and on average an acceptable accuracy in identifying achievement differences between individual students. They showed equal difficulties in judging performances of students with and without a different language background.

Specifically, the proven efficacy of psychotherapy for children and adolescents is essential. Thus, studies examining treatment efficacy and meta-analyses are necessary to compare effect sizes of individual therapeutic interventions between treatment groups and waiting control groups. Assessment of 138 primary studies from 1993-2009 documented the efficacy of psychotherapy for children and adolescents. Furthermore, behavioural therapy outperformed non-behavioural interventions, as 90 % of behavioural interventions showed larger effect sizes compared to non-behavioural psychotherapy. Analysis of moderator variables demonstrated an improved treatment efficacy for individual therapy, inclusion of the family, treatment of internalised disorders, and in clinical samples. Stability of psychotherapeutic treatment effects over time was demonstrated.

More than half of the girls and a third of the boys are dissatisfied with their weight. Nearly 70% of the male participants were unhappy with their muscles. Both forms of body dissatisfaction are influenced by similar sociocultural and psychological factors. While weight dissatisfaction leads to weight reduction strategies and disturbed eating, muscle dissatisfaction results in muscle enhancement methods. Potential harmful consequences of excessive muscle building techniques are discussed. The data emphasize the need for a sex-specific investigation of body dissatisfaction and its consequences. Body image aspects relevant to boys should be added to intervention and prevention approaches.

JF - Praxis der Kinderpsychologie und Kinderpsychiatrie : Ergebnisse aus Psychotherapie, Beratung und Psychiatrie N2 - Past research indicates an association in adults and young people of emotional and contextual factors with a higher risk for the development of eating disorders or obesity. Few studies focus on problematic eating patterns in childhood, especially in association with parental feeding strategies. 482 mothers completed a questionnaire about eating behaviors and the weight status of their 1- to 10-year-old child as well as their own feeding strategies. A classification of the child's eating behavior (food responsiveness, emotional eating, external eating, eating time and meal structure) using hierarchical cluster analysis revealed a conspicuous eating pattern (10 %) showing above-average values in all eating behaviors. Controlling for weight and demographic variables mothers of children with conspicuous eating patterns were characterized by restrictive strategies and were less likely to encourage or facilitate their child to control his or her eating. Similar problematic eating patterns were also identified in early childhood. The association of maternal feeding strategies - beyond weight control issues - with conspicuous eating patterns in children might indicate a possibility of early prevention through parent training.

Recent work discovered suppression of visual bursts in the superior colliculus around the time of microsaccades, tiny jerks of the eyes that support visual perception while gaze is fixed. This finding suggests that corollary discharge, supporting visual stability when rapid eye movements drastically shift the retinal image, may also exist for the smallest saccades.
