Transactional models between personality and alcohol involvement: a further examination

Although correlated changes between personality and alcohol involvement have been shown, the functional relation between these constructs is also of theoretical and clinical interest. Using bivariate latent difference score models, we examined transactional relations (i.e., personality predicting changes in alcohol involvement, which in turn predicts changes in personality) across two distinct but overlapping developmental time frames (i.e., across college and during young adulthood) using two large, prospective samples. Across college, there was some evidence that alcohol involvement predicted changes in personality; however, these findings were limited to models that included more proximal measures of alcohol use. When examined across a longer timeframe, we found no evidence that alcohol involvement significantly predicted changes in personality but found some evidence that personality predicted changes in alcohol use. We did find reliable evidence of correlated changes between personality and alcohol use, especially during emerging adulthood. The findings from our datasets highlight that the impact of alcohol involvement on personality change may be limited to shorter intervals during specific developmental time-frames and that the relation between changes in personality and alcohol involvement may be best viewed from a noncausal perspective.     

Operating characteristics of the implicit learning system supporting serial interception sequence learning

The memory system that supports implicit perceptual-motor sequence learning relies on brain regions that operate separately from the explicit, medial temporal lobe memory system. The implicit learning system therefore likely has distinct operating characteristics and information processing constraints. To attempt to identify the limits of the implicit sequence learning mechanism, participants performed the serial interception sequence learning (SISL) task with covertly embedded repeating sequences that were much longer than most previous studies: ranging from 30 to 60 (Experiment 1) and 60 to 90 (Experiment 2) items in length. Robust sequence-specific learning was observed for sequences up to 80 items in length, extending the known capacity of implicit sequence learning. In Experiment 3, 12-item repeating sequences were embedded among increasing amounts of irrelevant nonrepeating sequences (from 20 to 80% of training trials). Despite high levels of irrelevant trials, learning occurred across conditions. A comparison of learning rates across all three experiments found a surprising degree of constancy in the rate of learning regardless of sequence length or embedded noise. Sequence learning appears to be constant with the logarithm of the number of sequence repetitions practiced during training. The consistency in learning rate across experiments and conditions implies that the mechanisms supporting implicit sequence learning are not capacity-constrained by very long sequences nor adversely affected by high rates of irrelevant sequences during training.     

Enhancing visuospatial performance through video game training to increase learning in visuospatial science domains

Although previous research has demonstrated that performance on visuospatial assessments can be enhanced through relevant experience, an unaddressed question is whether such experience also produces a similar increase in target domains (such as science learning) where visuospatial abilities are directly relevant for performance. In the present study, participants completed either spatial or nonspatial training via interaction with video games and were then asked to read and learn about the geologic topic of plate tectonics. Results replicate the benefit of playing appropriate video games in enhancing visuospatial performance and demonstrate that this facilitation also manifests itself in learning science topics that are visuospatial in nature. This novel result suggests that visuospatial training not only can impact performance on measures of spatial functioning, but also can affect performance in content areas in which these abilities are utilized.     

Are You Minority Enough? Language Ability Affects Targets' and Perceivers' Assessments of a Candidate's Appropriateness for Affirmative Action

In the present study, we focus on Spanish language ability as a predictor of the extent to which Latinos are viewed by both others and themselves as full-fledged minorities. Study 1 shows that perceivers viewed Latinos described as Spanish speakers as more appropriate for race-based affirmative action than Latinos who were unable to speak Spanish (controlling for intellectual competence evaluations). Moreover, the affirmative action advantage that the Spanish-speaking Latinos had over the non-Spanish-speaking Latinos was explained by perceivers viewing the Spanish speakers as having greater minority status. The results of Study 2 suggest that Spanish-speaking ability is related to self-perceptions of minority status among Latinos. Like their perceivers in Study 1, Latinos who have less Spanish-speaking ability feel less Latino and report reluctance to apply for race-based assistance in the form of academic minority scholarships.     

Gaze-fixation and pupil dilation in the processing of emotional faces: The role of rumination

Sustained attentional processing of negative information plays a significant role in the development and maintenance of depression. The present study examines the relationships between rumination, a relevant factor in information processing in depression, and the attentional mechanisms activated in individuals with different levels of depression severity when attending to emotional information (i.e., sad, angry and happy faces). Behavioural and physiological indicators of sustained processing were assessed in 126 participants (39 dysphoric and 87 non-dysphoric) using eye-tracking technology. Pupil dilation and total time attending to negative faces were correlated with a global ruminative style in the total sample once depression severity was controlled. Furthermore, in dysphoric participants the brooding component of rumination was specifically associated with the total time attending to sad faces. Finally, bootstrapping analyses showed that the relationships between global rumination and pupil diameter to emotional faces were accounted by total time attending to emotional faces, specifically for participants reporting lower levels of depression severity. The results support the idea that sustained processing of negative information is associated with a higher ruminative style and indicate differential associations between these factors at different levels of depressive symptomatology.     

Working through the pain: Working memory capacity and differences in processing and storage under pain

It has been suggested that pain perception and attention are closely linked at both a neural and a behavioural level. If pain and attention are so linked, it is reasonable to speculate that those who vary in working memory capacity (WMC) should be affected by pain differently. This study compares the performance of individuals who differ in WMC as they perform processing and memory span tasks while under mild pain and not. While processing performance under mild pain does not interact with WMC, the ability to store information for later recall does. This suggests that pain operates much like an additional processing burden, and that the ability to overcome this physical sensation is related to differences in WMC.     

Integrating Contextual Issues in Ethical Decision Making

Many issues in ethics arise in relation to the contexts in which psychologists work. However, most ethical decision-making models reproduce the way in which psychologists tend to approach ethics by focusing on ethical dilemmas and proposing a step-by-step response to deal with them. Although these models might be useful, their emphasis on reactive approaches and their lack of contextualization constitute significant limitations on their applicability. In this article, an approach to ethical decision making that highlights the importance of the context in developing proactive strategies to solve ethical issues is proposed. This approach is further explained through its application to medical and rural settings. The implications of these suggestions to the training in ethics are finally discussed.

Investigating Separate and Concurrent Approaches for Item Parameter Drift in 3PL Item Response Theory Equating

This study examines separate and concurrent approaches to combine the detection of item parameter drift (IPD) and the estimation of scale transformation coefficients in the context of the common item nonequivalent groups design with the three-parameter item response theory equating. The study uses real and synthetic data sets to compare the two approaches based on IPD flagging rates, type I error and power rates, and recovery of scale transformation coefficients. Results indicate that the two approaches render similar outcomes with stable anchor sets. However, they can produce dissimilar results with unstable anchor sets because of differences in the performance of their IPD components. Further, the findings of this study caution about working backward from equated cut scores to motivate the selection of an anchor set.     

Evaluating the Effects of Creative Journal Arts Therapy for Survivors of Domestic Violence

The authors implemented a small series (N = 3) single-case research design to assess the effectiveness of a 9-session creative arts therapy treatment program for adult survivors of domestic violence. Analysis of participants’ scores on the Outcome Questionnaire (OQ-45.2) and Brief Resilience Scale using the percentage of nonoverlapping data procedure yielded treatment effects indicating that a creative arts therapy treatment program may be effective for reducing mental health symptoms and improving resiliency. It is recommended that this body of research continue for other educational, work, and health settings.
