Representation of dynamic spatial configurations in visual short-term memory

Locations of multiple stationary objects are represented on the basis of their global spatial configuration in visual short-term memory (VSTM). Once objects move individually, they form a global spatial configuration with varying spatial inter-object relations over time. The representation of such dynamic spatial configurations in VSTM was investigated in six experiments. Participants memorized a scene with six moving and/or stationary objects and performed a location change detection task for one object specified during the probing phase. The spatial configuration of the objects was manipulated between memory phase and probing phase. Full spatial configurations showing all objects caused higher change detection performance than did no or partial spatial configurations for static and dynamic scenes. The representation of dynamic scenes in VSTM is therefore also based on their global spatial configuration. The variation of the spatiotemporal features of the objects demonstrated that spatiotemporal features of dynamic spatial configurations are represented in VSTM. The presentation of conflicting spatiotemporal cues interfered with memory retrieval. However, missing or conforming spatiotemporal cues triggered memory retrieval of dynamic spatial configurations. The configurational representation of stationary and moving objects was based on a single spatial configuration, indicating that static spatial configurations are a special case of dynamic spatial configurations.     

Influencing and adjusting in daily emotional situations: a comparison of European and Asian American action styles

Emotions are for action, but action styles in emotional episodes may vary across cultural contexts. Based on culturally different models of agency, we expected that those who engage in European-American contexts will use more influence in emotional situations, while those who engage in East-Asian contexts will use more adjustment. European-American (N=60) and Asian-American (N=44) college students reported their action style during emotional episodes four times a day during a week. Asian Americans adjusted more than European Americans, whereas both used influence to a similar extent. These cultural differences in action style varied across types of emotion experienced. Moreover, influencing was associated with life satisfaction for European Americans, but not for Asian Americans.     

Examining School Counseling Students' Multicultural and Sexual Orientation Competencies Through a Cross‐Specialization Comparison

Professional school counselors have an opportunity to directly address the educational, emotional, and social problems facing lesbian, gay, bisexual, transgender, and questioning youth. The purpose of this study was to examine the multicultural and sexual orientation counselor competencies of school counseling students through a cross‐specialization comparison with community agency students. Results indicate that school counseling students had significantly lower self‐reported multicultural and sexual orientation counselor competency scores. The findings and their implications are discussed.     

Individual differences in face identification postdict eyewitness accuracy

Eyewitnesses frequently mistake innocent suspects for the culprits of an observed crime, and such misidentifications have caused the wrongful convictions of many innocent people. This study attempted to establish the accuracy of individual eyewitnesses by assessing their ability to process unfamiliar faces. Observers viewed a staged crime and later tried to select the culprit from an identity lineup. This was followed by a face test that provides a laboratory analogue to lineup identifications. We found that this face test could determine the reliability of individual witnesses when a positive eyewitness identification had been made. Importantly, this was possible based on the specific response that a witness had made and without prior knowledge of whether the culprit was actually present in the lineup. These findings demonstrate that individual differences in face processing provide a potential instrument for postdicting eyewitness accuracy and for preventing miscarriages of justice.     

Fisher transformation based confidence intervals of correlations in fixed- and random-effects meta-analysis

Meta-analyses of correlation coefficients are an important technique to integrate results from many cross-sectional and longitudinal research designs. Uncertainty in pooled estimates is typically assessed with the help of confidence intervals, which can double as hypothesis tests for two-sided hypotheses about the underlying correlation. A standard approach to construct confidence intervals for the main effect is the Hedges-Olkin-Vevea Fisher-z (HOVz) approach, which is based on the Fisher-z transformation. Results from previous studies (Field, 2005, Psychol. Meth., 10, 444; Hafdahl and Williams, 2009, Psychol. Meth., 14, 24), however, indicate that in random-effects models the performance of the HOVz confidence interval can be unsatisfactory. To this end, we propose improvements of the HOVz approach, which are based on enhanced variance estimators for the main effect estimate. In order to study the coverage of the new confidence intervals in both fixed- and random-effects meta-analysis models, we perform an extensive simulation study, comparing them to established approaches. Data were generated via a truncated normal and beta distribution model. The results show that our newly proposed confidence intervals based on a Knapp-Hartung-type variance estimator or robust heteroscedasticity consistent sandwich estimators in combination with the integral z-to-r transformation (Hafdahl, 2009, Br. J. Math. Stat. Psychol., 62, 233) provide more accurate coverage than existing approaches in most scenarios, especially in the more appropriate beta distribution simulation model.

The role of effect grouping in free-choice response selection

Which motor actions are preferred to replace an initially planned but momentary not executable action? Previous research (Khan, Mourton, Buckolz, Adams, & Hayes, 2010, Acta Psychologica) suggests that anatomical constraints seem to be a major determinant for such choices: For example, participants more frequently chose to respond with the finger homologous to the prepared one. We argue that in this case finger homology is confounded with action effect similarity, and action effects have been ascribed a crucial role in action selection. We report two experiments. Experiment 1 replicated the results obtained by Khan et al. In Experiment 2, we introduced visual action effects in the paradigm. Results from this experiment clearly point to a role of effect similarity in addition to mere finger homology status for the choice frequency effect.     

A quarter of a century of job transitions in Germany

By examining trends in intra-organizational and inter-organizational job transition probabilities among professional and managerial employees in Germany, we test the applicability of mainstream career theory to a specific context and challenge its implied change assumption. Drawing on data from the German Socio-Economic Panel (GSOEP), we apply linear probability models to show the influence of time, economic cycle and age on the probability of job transitions between 1984 and 2010. Results indicate a slight negative trend in the frequency of job transitions during the analyzed time span, owing to a pronounced decrease in intra-organizational transitions, which is only partly offset by a comparatively weaker positive trend towards increased inter-organizational transitions. The latter is strongly influenced by fluctuations in the economic cycle. Finally, the probability of job transitions keeps declining steadily through the course of one's working life. In contrast to inter-organizational transitions, however, this age effect for intra-organizational transitions has decreased over time.     

The luck argument against event-causal libertarianism: It is here to stay

The luck argument raises a serious challenge for libertarianism about free will. In broad outline, if an action is undetermined, then it appears to be a matter of luck whether or not one performs it. And if it is a matter of luck whether or not one performs an action, then it seems that the action is not performed with free will. This argument is most effective against event-causal accounts of libertarianism. Recently, Franklin (Philosophical Studies 156:199–230, 2011) has defended event-causal libertarianism against four formulations of the luck argument. I will argue that three of Franklin’s responses are unsuccessful and that there are important versions of the luck challenge that his defense has left unaddressed.
