  abstract  = {Is a specific disorder of arithmetic skills as common as reading/spelling disorder?Background: Referring to the prevalence rates of learning disorders in the research literature, the numbers of mathematics disorder and reading/ spelling disorder are often reported to be identical. However, the correlation between intelligence level and reading/ spelling skills is much weaker than between intelligence and arithmetic skills. If the same definition criterion is applied to both disorders, a lower prevalence rate for mathematics disorder should be expected. Objective: Are there differences in the prevalence estimates for learning disorders depending on the definition criterion? Method: A large representative sample of German students (N = 1970) was used to review the hypothesis. Results: Depending on the definition criterion, we could show a prevalence range of mathematics disorder between 0.1\% and 8.1\% in the same sample. Using the same definition criterion for both learning disorders, there are two to three times as many students with reading/spelling disorder than those with mathematics disorder. Discussion: Whenever children with reading/spelling disorder are compared to children with mathematics disorder, the same definition criterion has to be applied.},

  abstract  = {Adipositas ist ein ernstzunehmendes gesundheitliches Problem, welches das physische und psychosoziale Wohlbefinden von Kindern und deren Eltern beeintraechtigt und somit wirksamer praeventiver Ansaetze bedarf. Dabei ist es bedeutsam, welche Barrieren, Anreize und Selbstwirksamkeitserwartungen Eltern fuer oder gegen die Teilnahme an solchen Programmen entscheiden lassen. Ziel der Studie war es zu untersuchen, wie Muetter ihre Selbstwirksamkeits- und Handlungsergebniserwartungen beschreiben und inwieweit sich soziodemografische Aspekte auf diese Einschaetzungen auswirken. Insgesamt wurden 219 Muetter von Kindern im Alter von 3-6 Jahren befragt. Mehr als die Haelfte der befragten Muetter waren uebergewichtig bzw. adipoes sowie 12\% der Kinder. Es ergaben sich weder fuer das Alter und das Geschlecht des Kindes noch fuer das Familieneinkommen Unterschiede in den Handlungsergebniserwartungen. Muetter mit geringerer Bildung nahmen weniger Anreize wahr und Muetter mit uebergewichtigen Kindern sahen weniger Barrieren fuer eine Programmteilnahme. uebergewichtige Muetter dagegen bewerteten die Barrieren und Anreize hoeher als normalgewichtige Muetter. Hinsichtlich der Selbstwirksamkeit ergaben sich ebenfalls Unterschiede bezueglich der Bildung und des Gewichts der Mutter sowie des Kindes. Im Vorfeld einer Intervention sollte ein Beratungsgespraech bezogen auf die muetterlichen Erwartungen stattfinden, um die Teilnahmebereitschaft und den Programmerfolg zu unterstuetzen.},

  abstract  = {OBJECTIVE: To examine factors associated with the maternal perception of the weight status in related and unrelated children and to examine whether associated health risks for children's physical and mental health are recognized. PATIENTS AND METHODS: Two hundred nineteen mothers with children between 3 and 6 years of age took part in this study. The participating mothers were recruited from inpatient clinics and kindergartens. Parents were presented with 9 silhouettes representing different age- and gender-specific BMI percentiles. Demographic and weight-related variables were assessed with regard to their influence on the accuracy of the maternal weight estimation in general and for their own child. RESULTS: Of the participating mothers, 64.5\% identified the overweight silhouettes of preschool- aged children correctly. However, only 48.8\% of the mothers identified the overweight silhouettes associated with an increased risk for physical health problems, and 38.7\% identified the silhouettes associated with an increased mental health risk. Mothers with a lower educational background were more likely to misclassify the overweight silhouettes and underestimate the associated health problems. For their own child, only 40.3\% of the mothers chose silhouettes that were in agreement with the objective weight status of their child. This underestimation was associated with a higher maternal and child weight status but not with a general inability to identify the weight status of children. CONCLUSIONS: Identifying unrelated overweight silhouettes is influenced by maternal education level, whereas estimating their own child's weight status is influenced by the weight status of the mother and the child. Hence, feedback on the child's risk to become overweight is necessary to increase maternal risk awareness and willingness to take part in prevention programs.},

  abstract  = {Active motor processes are present in many sensory systems to enhance perception. In the human visual system, miniature eye movements are produced involuntarily and unconsciously when we fixate a stationary target. These fixational eye movements represent self-generated noise which serves important perceptual functions. Here we investigate fixational eye movements under the influence of external noise. In a two-choice discrimination task, the target stimulus performed a random walk with varying noise intensity. We observe noise-enhanced discrimination of the target stimulus characterized by a U-shaped curve of manual response times as a function of the diffusion constant of the stimulus. Based on the experiments, we develop a stochastic information-accumulator model for stimulus discrimination in a noisy environment. Our results provide a new explanation for the constructive role of fixational eye movements in visual perception.},

Students were assigned to any one of three intervention conditions or to a traditional instruction condition (control condition). Training students were taught four reading strategies (summarizing, questioning, clarifying, predicting) and practiced these strategies in small groups (reciprocal teaching), pairs, or instructor-guided small groups. At both the post- and follow-up test the intervention students attained higher scores on an experiment-developed task of reading comprehension and strategy use than the control students who received traditional instruction. Furthermore, students who practiced reciprocal teaching in small groups outperformed use than the control students who received traditional instruction groups on a standardized reading comprehension test.},

  abstract  = {R. Sekuler, P. Tynan, and E. Levinson (1973) found that when 2 characters are presented side-by-side with a short onset asynchrony, subjectively, they often appear in a "first-left, then-right" order. The authors of this article conducted 6 experiments in which observers judged the temporal order (TOJs) in which 2 digits were presented. They found a consistent TOJ benefit (larger d') when the numerically smaller digit was presented first, even though this semantic information was irrelevant to the task and unrelated to the correct response. They concluded that digits located to the left of the mental number line are transmitted faster to a central comparison stage, which represents an "internal counterpart" to the Sekuler et al. (1973) finding regarding external locations. A corresponding benefit is found for letters pairs (e.g., A-Z) and also for mixed digit-letter pairs (e.g., I-Z).},

  abstract  = {Previous studies that have examined the relationship between implicit and explicit motive measures have consistently found little variance overlap between both types of measures regardless of thematic content domain (i.e., power, achievement, affiliation). However, this independence may be artifactual because the primary means of measuring implicit motivescontent-coding stories people write about picture cuesare incommensurable with the primary means of measuring explicit motives: having individuals fill out self-report scales. To provide a better test of the presumed independence between both types of measures, we measured implicit motives with a Picture Story Exercise (PSE; McClelland, Koestner, Weinberger, 1989) and explicit motives with a cue- and response-matched questionnaire version of the PSE (PSE-Q) and a traditional measure of explicit motives, the Personality Research Form (PRF; Jackson, 1984) in 190 research participants. Correlations between the PSE and the PSE-Q were small and mostly nonsignificant, whereas the PSE- Q showed significant variance overlap with the PRF within and across thematic domains. We conclude that the independence postulate holds even when more commensurable measures of implicit and explicit motives are used.},

Widrige familiaere Bedingungen, Entwicklungsverzoegerungen und psychische Stoerungen scheinen mit Delinquenz als eher persistentem Verhalten assoziiert.},
