TY - JOUR A1 - Brunstein, Joachim Clemens A1 - Schmitt, C. H. T1 - Assessing individual differences in achievement motivation with the Implicit Association Test N2 - The authors examined the validity of an Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) for assessing individual differences in achievement tendencies. Eighty-eight students completed an IAT and explicit self- ratings of achievement orientation, and were then administered a mental concentration test that they performed either in the presence or in the absence of achievement-related feedback. Implicit and explicit measures of achievement orientation were uncorrelated. Under feedback, the IAT uniquely predicted students' test performance but failed to predict their self-reported task enjoyment. Conversely, explicit self-ratings were unrelated to test performance but uniquely related to subjective accounts of task enjoyment. Without feedback, individual differences in both performance and enjoyment were independent of differences in either of the two achievement orientation measures. (C) 2004 Elsevier Inc.

Two types of these fixational eye movements are drift and microsaccades (small-amplitude saccades). We investigated fixational eye movements and binocular coordination using a statistical analysis that had previously been applied to human posture control. This random-walk analysis uncovered two different time scales in fixational eye movements and identified specific functions for microsaccades. On a short time scale, microsaccades enhanced perception by increasing fixation errors. On a long time scale, microsaccades reduced fixation errors and binocular disparity (relative to pure drift movements). Thus, our findings clarify the role of oculomotor processes during fixation Y1 - 2004 ER - TY - JOUR A1 - Engbert, Ralf A1 - Kliegl, Reinhold A1 - Longtin, Andre T1 - Complexity of eye movements in reading N2 - During reading, our eyes perform complicated sequences of fixations on words. Stochastic models of eye movement control suggest that this seemingly erratic behaviour can be attributed to noise in the oculomotor system and random fluctuations in lexical processing. Here, we present a qualitative analysis of a recently published dynamical model [Engbert et al., 2002] and propose that deterministic nonlinear control accounts for much of the observed complexity of eye movement patterns during reading. Based on a symbolic coding technique we analyze robust statistical features of simulated fixation sequences Y1 - 2004 ER - TY - JOUR A1 - Ihle, Wolfgang A1 - Ahle, M. E. A1 - Jahnke, Dörte A1 - Esser, Günter T1 - Guidelines for the assessment and psychotherapy of depressive disorders in childhood and adolescence: An evidence-based discussion paper N2 - An outline of evidence-based guidelines for the assessment and treatment of depressive disorders in childhood and adolescence is presented. Depressive disorders in children and adolescents are marked by core symptoms similar to those seen in adults, although symptom expression varies greatly with developmental stage. These disorders are common, especially in adolescence, chronic, and recurrent, and are associated with comorbid conditions such as anxiety disorders, conduct disorders, and substance use disorders. Effective treatment approaches for the prevention of depressive disorders and the acute treatment of mild and moderate depressive disorders are available. The psychotherapeutic interventions of choice are currently cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). The antidepressants of choice are currently selective serotonin reuptake inhibitors (SSRI). Especially on relapse prevention and the evaluation of the combination of psychotherapy with antidepressant medication further studies are necessary Y1 - 2004 SN - 0942-5403 ER - TY - JOUR A1 - Kliegl, Reinhold A1 - Grabner, Ellen A1 - Rolfs, Martin A1 - Engbert, Ralf T1 - Length, frequency, and predictability effects of words on eye movements in reading Y1 - 2004 ER - TY - JOUR A1 - Koch, Sabine A1 - Titze, Karl A1 - Zimmer, Ulrike A1 - Lehmkuhl, Ulrike A1 - Rauh, Hellgard A1 - Helge, Hans T1 - Growth of children exposed to antiepileptic medications in the womb N2 - Antiepileptic drugs are suspected of being weakly teratogenic in humans. In a prospective longitudinal study, we assessed growth parameters of children from birth to adolescence who had been prenatally exposed to various antiepileptic drugs and compared them to non-exposed control children matched for parental body length, social status, and maternal nicotine consumption during pregnancy as well as for parity. While no differences in mean head circumferences could be ascertained in the group of exposed children at 1, 6, and 14 years, differences were measured in body length at I year. The differences were more pronounced for both measurements when therapy forms and types of drugs were considered: polytherapy and phenobarbitone therapy (which was usually part of polytherapy) of the mother appeared to have an influence on the children's growth. Children exposed to polytherapy and phenobarbitone (as single drug or as part of polytherapy) had smaller head circumferences and were shorter. We assume an influence of polytherapy and phenobarbitone therapy taken by the epileptic woman during pregnancy on the growth of the child into adolescence Y1 - 2004 SN - 0026-9298 ER - TY - JOUR A1 - Krahé, Barbara A1 - Bieneck, Steffen A1 - Scheinberger-Olwig, Renate T1 - Sexual scripts in adolescence N2 - To explore the sexual scripts of adolescents, 131 10th and 11th graders generated descriptions of three scripts for sexual interactions: (1) the prototypical script for the first consensual sexual intercourse with a new partner attributed to adolescents in general; (2) the script for the first consensual sexual intercourse with a new partner endorsed by themselves individually; (3) the script for a nonconsensual sexual intercourse. Normative acceptance of risk elements of sexual interactions and acceptance of physical force to obtain sexual intercourse with a non-consenting partner were also measured. The results showed that the individual and general scripts for consensual sexual interactions reflected traditional gender roles. The script for the nonconsensual intercourse was based on the <> stereotype. Compared to the general scripts for the age group as a whole, individual scripts were more conservative, containing fewer risk elements. Normative acceptance of risk elements predicted the extent to which risk elements were part of the general and individual scripts. In addition, acceptance of physical force predicted the risk elements of the individual scripts Y1 - 2004 SN - 0044-3514 ER - TY - JOUR A1 - Krahé, Barbara A1 - Möller, Ingrid T1 - Playing violent electronic games, hostile attributional style, and aggression-related norms in German adolescents N2 - The relationship was examined between exposure to and preference for violent electronic games and aggressive norms as well as hostile attributional style. Following a pilot study to sample widely used electronic games varying in violent content, 231 eighth-grade adolescents in Germany reported their use of and attraction to violent electronic games. They also completed measures of hostile attributional style and endorsement of aggressive norms. There were significant gender differences in usage and attraction to violent electronic games, with boys scoring higher than girls. Significant relationships were found between attraction to violent electronic games and the acceptance of norms condoning physical aggression. Violent electronic games were linked indirectly to hostile attributional style through aggressive norms. The findings are discussed with respect to North American research on the aggression-enhancing effect of violent electronic games.

Die vorliegende Studie untersucht, ob das Muster statt durch einen üblicherweise postulierten unspezifischen durch einen spezifischen Mechanismus erklärt werden kann: die mit dem Alter abnehmende Reliabilität episodischer Akkumulatoren. In sechs Reaktionszeit-Experimenten wurden junge und ältere Erwachsene verglichen, dabei wurden frühe kognitive (Stroop-Bedingung) und episodische Schwierigkeit (Reiz-Reaktions-Zuordnung) orthogonal manipuliert. Die vorhergesagte Dreifachinteraktion der beiden Faktoren mit dem Alter zeigte sich über die Experimente hinweg relativ konsistent. Eine modifizierte Brinley-Analyse ergibt deutlich unterschiedliche Steigungen der Regressionsgeraden im Alt-Jung-Raum für niedrige und hohe episodische Schwierigkeit. Als methodischer Beitrag wird im Anhang ein zur modifizierten Brinley-Analyse passendes Regressionsmodell entwickelt, das aus einigen einfachen Verarbeitungsannahmen folgt. Es wird gezeigt, dass in einer klassischen Brinley Metaanalyse die Steigung neben der theoretisch interessierenden Varianz von theoretisch uninteressanter Zwischen-Experiment-Varianz beeinflusst wird. N2 - The age-by-complexity effect is the dominant empirical pattern in cognitive aging. The current report investigates whether a specific high-level mechanism---an age-related decrease in the reliability of episodic accumulators---can account for the age-by-complexity-effect, which is commonly assumed to be caused by an unspecific, low-level deficit. Groups of younger and older adults are compared in six reaction time experiments, using orthogonal manipulations of early cognitive difficulty (e.g., Stroop condition) and episodic demands (e.g., stimulus-response mapping). The predicted three-way interaction of age and the two factors was observed fairly consistently across experiments. A modified Brinley analysis shows that different regression slopes in old-young-space are required for conditions with low and high episodic difficulty. As a methodological contribution, a Brinley regression model following from certain simple processing assumptions is developed. It is shown that in contrast to a standard Brinley meta-analysis, the regression slopes in this model are not influenced by theoretically un-interesting between-experiment variance.

In Experiment 1, 6 students practiced updating 2 items in working memory through 2 sequences of operations (1 numerical, 1 spatial). In different blocks, imperative stimuli for the 2 sequences of operations were presented either simultaneously or sequentially. Initially, most participants experienced substantial dual-task costs. After 24 sessions of practice, operation latencies for simultaneous presentation were equal to the maximum of times for the 2 operations in the sequential condition, suggesting perfect timesharing. Experiment 2 showed that a reduction of dual-task costs requires practice on the combination of the 2 updating tasks, not just practice on each individual task. Hence, the reduction of dual-task costs cannot be explained by shortening or automatization of individual operations Y1 - 2004 SN - 0096-1523 ER - TY - JOUR A1 - Oberauer, Klaus A1 - Suss, H. M.
