Read-out of emotional information from iconic memory: the longevity of threatening stimuli

Previous research has shown that emotional stimuli are more likely than neutral stimuli to be selected by attention, indicating that the processing of emotional information is prioritized. In this study, we examined whether the emotional significance of stimuli influences visual processing already at the level of transient storage of incoming information in iconic memory, before attentional selection takes place. We used a typical iconic memory task in which the delay of a poststimulus cue, indicating which of several visual stimuli has to be reported, was varied. Performance decreased rapidly with increasing cue delay, reflecting the fast decay of information stored in iconic memory. However, although neutral stimulus information and emotional stimulus information were initially equally likely to enter iconic memory, the subsequent decay of the initially stored information was slowed for threatening stimuli, a result indicating that fear-relevant information has prolonged availability for read-out from iconic memory. This finding provides the first evidence that emotional significance already facilitates stimulus processing at the stage of iconic memory.     

Die Validit?t dynamisch-ver?nderbarer Risikofaktoren bei der Vorhersage einschl?giger R��ckf?lle p?dosexueller Straft?ter

The present study examines the predictive validity of dynamic risk factors for the prediction of sexual recidivism in a sample of pedosexual offenders (N?=?135) released from the Austrian prison system between 2002 and 2005. Static-99 was used to rate static risk factors and in order to measure dynamic risk factors Stable-2000 and Stable-2007 were applied. In addition to the demonstration of results about the interrater reliability the results about the predictive and incremental validity of the dynamic risk assessment are presented. After a mean follow-up period of 5½ years Static-99, Stable-2000 and Stable-2007 showed excellent interrater reliability and good predictive validity for the prediction of sexual recidivism. Furthermore, Stable-2007 showed better predictive accuracy than its predecessor and added incremental predictive validity beyond Static-99.     

Beyond quantitative decline: conceptual shifts in adolescents' development of interest in mathematics

Research has shown that the average values for academic interest decrease during adolescence. Looking beyond such quantitative decline, we explored qualitative change of interest in the domain of mathematics across adolescence. Study 1 was based on a longitudinal data set (annual assessments from Grade 5 to Grade 9; N = 3,193). Latent variable modeling showed that the measurement coefficients of the latent variable of interest (intercepts, structural weights, and error variances) significantly differed across time points, indicating structural changes of the construct. Study 2 was based on interviews with adolescents (Grades 5 and 9, N = 70). Cognitive validation was used to explore differences in subjective concepts of interest across age groups. As expected, there were significant age-related differences, indicating a shift from an affect-laden concept in 5th grade to a more cognitively oriented concept in 9th grade. The findings suggest that developmental research should integrate quantitative and qualitative perspectives of construct change over time and pay more attention to issues of measurement invariance and qualitative changes of constructs over time.     

To judge a book by its weight you need to know its content: Knowledge moderates the use of embodied cues

Participants evaluated a book as more important when it weighed heavily in their hands (due to a concealed weight), but only when they had substantive knowledge about the book. Those who had read a synopsis (Study 1), had read the book (Study 2) and knew details about its plot (Study 3) were influenced by its weight, whereas those unfamiliar with the book were not. This contradicts the widely shared assumption that metaphorically related perceptual inputs serve as heuristic cues that people primarily use in the absence of more diagnostic information. Instead, perceptual inputs may increase the accessibility of metaphorically congruent knowledge or may suggest an initial hypothesis that is only endorsed when supporting information is accessible.     

Possibilities of objective assessment of the course of activation in ideomotor training

An active exploration of movement tasks is accompanied with central nervous activation. Its systematical examination needs a teamwork of scientists of various branches of knowledge (i.e. physiology, psychology, sport sciences). Mental training (motor imagination - MI) was chosen as a model for such examinations. In connection with the execution of MI there are characteristic chances of the mean alpha frequency of the EEG, heart rate, respiration rate and skin conductance. The time course of these parameters depends on the number, the duration and the sequence of MI. A graduated submaximal load on ergometer has no influence on the course of the examined parameters. Our investigation allows the conclusion that different activation processes go on within different subsystems during the execution of MI. From a physiological point of view it seems to be necessary that a concrete paradigm of MI must be examined concerning the course of the parameters and, thus, to guarantee the effort of MI.     

Cognitive processes mediating behavioral change.

The present experiment was designed to test the theory that psychological procedures achieve changes in behavior by altering the level and strength of self-efficacy. In this formulation, perceived self-efficacy. In this formulation, perceived self-efficacy influences level of performance by enhancing intensity and persistence of effort. Adult phobics were administered treatments based upon either performance mastery experiences, vicarious experiences., or they received no treatment. Their efficacy expectations and approach behavior toward threats differing on a similarity dimension were measured before and after treatment. In accord with our prediction, the mastery-based treatment produced higher, stronger, and more generalized expectations of personal efficacy than did the treatment relying solely upon vicarious experiences. Results of a microanalysis further confirm the hypothesized relationship between self-efficacy and behavioral change. Self-efficacy was a uniformly accurate predictor of performance on tasks of varying difficulty with different threats regardless of whether the changes in self-efficacy were produced through enactive mastery or by vicarious experience alone.     

Causal Models of Physical Exercise Participation: Testing the Predictive Power of the Construct "Pressure to Change"

This study examines 2 different causal models to predict physical exercise motivation and behavior under a longitudinal perspective. The first model includes 5 latent variables that were hypothesized to have an impact on exercise intention and behavior: behavior-specific social support, exercise self-efficacy, perceived health benefits, perceived barriers, and subjective vulnerability to cardiovascular disease. The second model was based on all variables of the first model, but additionally included the new variable "pressure to change." Pressure to change was defined as the extent to which a person feels the necessity that specific personal life circumstances (e.g., health status, social relations) may not remain as they are and ought to be changed. It was hypothesized that the inclusion of health-related pressure to change would result in a better prediction of exercise intention. The proposed causal models were tested separately at the stages of exercise adoption and maintenance. Covariance structure analyses (LISREL) confirmed that pressure to change may be an important factor in the motivational process that leads to the adoption of regular physical exercise. Adding this latent variable to the basic model improved the amount of explained variance in exercise intention by 6%. Furthermore, the results did not support the assumption that cognitive control is critical especially during the acquisition of exercise behaviors, but may be less influential once the behavioral routines have been established. Our data rather indicate that regular physical exercise, even if performed on a regular basis for years, always remains a behavior that requires a high level of cognitive guidance.     

Gender differences in causal attributions by college students of performance on course examinations

Gender differences in causal attributions and emotions for imagined success and failure on examinations were investigated. Males made stronger ability attributions for success than females, whereas females emphasized the importance of studying and paying attention. Males more than females attributed failure to a lack of studying and low interest, but females were more likely than males to blame an F on a lack of ability. Females experienced stronger emotions than did males; they felt happier than males did after success but felt more like a failure than did males after imagining receiving an F on an examination. Some of the gender differences in causal attributions, especially for ability attributions, depended on the gender-type of the subject matter of the examinations. The implications of these findings are discussed.
