Measuring attention in the hemispheres: the lateralized attention network test (LANT)

The attention network test (ANT) is a brief computerized battery measuring three independent behavioral components of attention: Conflict resolution (ability to overcome distracting stimuli), spatial Orienting (the benefit of valid spatial pre-cues), and Alerting (the benefit of temporal pre-cues). Imaging, clinical, and behavioral evidence demonstrate hemispheric asymmetries in these attentional networks. We constructed a lateralized version of the ANT (LANT), with brief targets flashed in one or the other visual hemifield. We also modified the tests by including invalid spatial cues in order to measure the cost component of Orienting. In a series of experiments, we investigated the efficiency of the attention networks separately in each hemisphere. Participants exhibited significant estimates of all networks measured by the LANT, comparable to the ANT. The three networks were represented in each hemisphere separately and were largely comparable across the two hemispheres. We suggest that the LANT is an informative extension of the original ANT, allowing for measurement of the three attention networks in each hemisphere separately.     

Beyond “accident-proneness”: Using Five-Factor Model prototypes to predict driving behavior

Research on the association between personality traits and driving behavior as well as accident involvement has produced mixed results. In order to obtain empirical evidence for a consistent relation between personality and driving behavior, a prototype approach based on the Five-Factor Model (FFM) was applied. In two samples of drivers, cluster analyses of FFM scales revealed three prototypes that replicate previous ones. The prototypes, labeled Resilient, Overcontrolled, and Undercontrolled, were found to differ reliably in accident involvement and driving behavior, indicating differential accident liability. Undercontrollers are the most problematic drivers followed by Resilients, whereas Overcontrollers most consistently obey traffic rules and drive accordingly.     

Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.

The Consistency of Probabilistic Regresses. A Reply to Jeanne Peijnenburg and David Atkinson

In a recent paper, Jeanne Peijnenburg and David Atkinson [Studia Logica, 89(3):333-341 (2008)] have challenged the foundationalist rejection of infinitism by giving an example of an infinite, yet explicitly solvable regress of probabilistic justification. So far, however, there has been no criterion for the consistency of infinite probabilistic regresses, and in particular, foundationalists might still question the consistency of the solvable regress proposed by Peijnenburg and Atkinson.     

The contribution of negative reproductive experiences and chronic medical conditions to depression and pain among Israeli women

This study of 302 Israeli women sought to investigate the associations among stressful reproductive experiences (e.g. fertility problems, abortions, and traumatic births), chronic medical conditions, pain, and depression. The specific aims of the study were to examine (1) the effect of stressful reproductive experiences, chronic medical conditions, and pain on depressive symptoms and (2) the effect of stressful reproductive experiences, chronic medical conditions, and depressive symptoms on pain. Our findings corroborate with previous studies demonstrating that depression and pain are two interrelated, but different phenomena, which have both common and distinct risk factors. The findings are discussed in the light of stress and adaptation theories that point to the long-term effects of stressful life events on emotional and physiological aspects such as depression and pain.     

Multilingual Groups: Effects of Linguistic Ostracism on Felt Rejection and Anger,Coworker Attraction,Perceived Team Potency,and Creative Performance

We defined linguistic ostracism (LO) as any situation in which people converse in a language that others cannot understand (as opposed to linguistic inclusion [LI], in which people converse in a language that others do understand). Participants were exposed to either LO or LI by two Russian-speaking confederates. Participants then performed a creativity (brainstorming) task expecting to be evaluated individually or to reconvene with their groups and be evaluated collectively. Results revealed that targets of LO compared to LI reported more rejection and anger, less attraction toward their coworkers, and lower perceived team potency. In the group work condition, targets high in social self-efficacy (SSE) performed better following LO (compared to LI), whereas those low in SSE performed worse. No effects emerged in the individual work condition. Targets' levels of rejection sensitivity were positively associated with aggressively charged ideas following LO but not LI. We conclude that LO is psychologically aversive for targets and hampers group-based performance among those who lack confidence in their social abilities. Future areas of research as well as implications for multilingual organizations are discussed.     

Searching for the Right Word: Performance on Four Word-Retrieval Tasks Across Childhood

Word retrieval was assessed in 207 normally developing Hebrew-speaking children aged 8–17 through four tasks: picture naming, phonemic fluency, semantic fluency, and homophone meaning generation (HMGT). Scores on all tests correlated positively and significantly with participant age. Yet, age effects and the correlation between age and test scores were weakest for the naming test and strongest for the HMGT. We discuss the nature of the word search involved in each task and suggest that the more executive demands required by a test the steeper the slope of performance increase on this test.     

Cross-cultural differences in mental representations of time: evidence from an implicit nonlinguistic task

Across cultures people construct spatial representations of time. However, the particular spatial layouts created to represent time may differ across cultures. This paper examines whether people automatically access and use culturally specific spatial representations when reasoning about time. In Experiment 1, we asked Hebrew and English speakers to arrange pictures depicting temporal sequences of natural events, and to point to the hypothesized location of events relative to a reference point. In both tasks, English speakers (who read left to right) arranged temporal sequences to progress from left to right, whereas Hebrew speakers (who read right to left) arranged them from right to left, replicating previous work. In Experiments 2 and 3, we asked the participants to make rapid temporal order judgments about pairs of pictures presented one after the other (i.e., to decide whether the second picture showed a conceptually earlier or later time-point of an event than the first picture). Participants made responses using two adjacent keyboard keys. English speakers were faster to make "earlier" judgments when the "earlier" response needed to be made with the left response key than with the right response key. Hebrew speakers showed exactly the reverse pattern. Asking participants to use a space-time mapping inconsistent with the one suggested by writing direction in their language created interference, suggesting that participants were automatically creating writing-direction consistent spatial representations in the course of their normal temporal reasoning. It appears that people automatically access culturally specific spatial representations when making temporal judgments even in nonlinguistic tasks.
