Action video game experience affects oculomotor performance

Action video games have been show to affect a variety of visual and cognitive processes. There is, however, little evidence of whether playing video games can also affect motor action. To investigate the potential link between experience playing action video games and changes in oculomotor action, we tested habitual action video game players (VGPs) and non-video game players (NVGPs) in a saccadic trajectory deviation task. We demonstrate that spatial curvature of a saccadic trajectory towards or away from distractor is profoundly different between VGPs and NVGPs. In addition, task performance accuracy improved over time only in VGPs. Results are discussed in the context of the competing interplay between stimulus-driven motor programming and top–down inhibition during oculomotor execution.     

A psychobiographical analysis of Dambudzo Marechera's personal development through his writings

This study applied psychobiography to explore the personal development of Zimbabwean novelist Dambudzo Marechera – and particularly focus on psychological disintegration. For the evidence, we examined primary and secondary works on his life history with special attention to his literary works. Findings indicate that his early writings were autobiographical in nature, chronicling lived poverty, war and violence experiences. Later writings were somehow surrealistic and unstructured, marking a culmination of significant personal disintegration that started in early childhood. Other ancillary biographical evidence suggests self-perceptions as a cult-like figure, and what appears to be a limited social interest.     

Distracted by Details: Narrative Influence Following Conflicting Stories

Work on narrative influence has demonstrated that stories can have a strong effect on people's thoughts and attitudes. However, existing research has not addressed how people respond to multiple stories endorsing different conclusions. The current studies examined how reading two conflicting narratives influences people's decisions about a subsequent situation, with particular emphasis on how resemblances between the narratives and the situation moderate the effects. Across two studies, participants read two testimonials that described the successful use of different treatments for a medical disorder. Participants subsequently made treatment recommendations for a patient who resembled one of the testimonials in treatment-relevant ways. The key manipulation was whether the patient also resembled the other testimonial in treatment-irrelevant ways. Both studies found that these distracting, irrelevant similarities led to less appropriate treatment recommendations. The effect on decision confidence, however, was less clear, with some suggestion of both an increase (Study 1) and a decrease (Study 2) in confidence.     

THE EFFECT OF REPERTORY GRID SCALE SIZE AND RATING DIRECTION ON STRUCTURAL MEASURES OF DIFFERENTIATION

Previous work by Soldz and Soldz (1989) indicated that variations in repertory grid features can have a significant impact on the interpretation of the Landfield Functionally Independent Construction Score (FIC), which is a measure of cognitive differentiation. In this study, we showed that four different grid measures (FIC, Total number of zeroes, and the number of midpoint ratings used to indicate either equality or nonapplicability) can be effected by the use of a certain scale size (3-point, 7-point, 13-point), and by the direction of administration (completing the grid in a downwards direction vs. an across-wise direction). In addition, correlations between the number of zero ratings and the total FIC scores for each of the different scale sizes and directions showed evidence to support and to qualify previous work conducted by Soldz and Soldz (1989). In general, high positive correlations were found, suggesting the impact of zero ratings on FIC scores. But the magnitude of the correlations between the zero ratings and the total FIC scores varied as a function of the scale size, the direction of administration, and the meaning of the zero rating (neutrality vs. nonapplicability), raising theoretical, as well as procedural, considerations for future repertory grid research.     

On the robustness and the direction of the effect of cause‐related marketing

Two experiments are presented in this paper that explore the effect of cause‐related marketing (CRM) on product choice. To allow evaluation of the effect of experience and the role of individual differences, the experiments used a repeated choice setting. The results of Experiment 1 showed that the effect of CRM was stable over time. However, the direction of the effect was sensitive to the value of the product. CRM served as an equaliser: it helped disadvantaged alternatives and reduced the attractiveness of superior alternatives. Experiment 2 showed that the effect of CRM decreased but did not disappear in an easy choice task. These findings are summarised in a simple model and discussed in terms of their potential marketing applications. Copyright © 2003 Henry Stewart Publications.     

Relations between social and emotional competence and mental health: a construct validation study

Researchers working fairly independently of each other have created numerous measures of social and emotional competence (SEC). These measures tend to correlate (sometimes highly) with each other and with measures of stressful events, suggesting potential redundancy. We evaluated which, if any, SEC variables predicted unique variance in social and mental health after controlling for other SEC variables in the study and the impact of stressful events. Three-hundred and thirty-one university students participated in an anonymous, cross-sectional study. We measured stressful events, and a wide variety of SECs, including: social problem solving skill (effective problem orientation, automatic processing, and problem solving), alexithymia (difficulty identifying and describing emotions; minimising emotions), effective emotional control (low rumination, high impulse control, high aggression control, low defensive inhibiting of emotions), and level of emotional awareness. We also assessed a variety of aspects of social and mental health (e.g. depression, anxiety, hopelessness, suicidal ideation, life satisfaction, social support). Covariance analyses revealed that all SEC measures except minimising emotions had significant incremental value over the other measures and over stressful events in predicting social and mental health. The optimal set of predictors differed depending upon the type of health predicted. These findings have important implications for the design of social and emotional intervention programs.
