Neurocognitive Performance in Alcoholics: Is Polysubstance Abuse Important?

The neurocognitive effects of alcohol have been frequently examined. Studies reveal a wide array of cognitive deficits. Attempts to develop a parsimonious model for these effects have been difficult because of the intra- and intersubject variability. Complicating the development of a model of cognitive deficits in substance abusers is the common practice of polysubstance abuse. The use of theoretical models that focus on the underlying cognitive processes offers flexibility while maintaining sufficient theoretical precision. This article briefly reviews the literature on neurocognitive changes associated with substance abuse as well as the various theoretical models that have been studied. It also provides an overview of recovery of function. Its primary objective is to evaluate cognitive function among alcoholic subtypes, defined by patterns of other drug use. This analysis suggests there are significant differences in neurocognitive function among these subtypes.     

Leader Positivity and Follower Creativity: An Experimental Analysis

Using an experimental research design, 191 working adults were randomly assigned to two experimental conditions in order to test a theoretical model linking leader and follower positive psychological capital (PsyCap). Multiple methods were used to gather information from the participants. We found when leader PsyCap was manipulated experimentally, it was positively related to follower PsyCap. Subsequently, follower PsyCap was significantly related to employee's originality of ideas; one important component of creativity in the workplace. We discuss the theoretical contributions of linking leader and follower PsyCap in what emerges as a directional contagion effect, and the mediating role of follower PsyCap in enhancing follower creative task performance. Further, employee selection and development as well as leadership development practical implications are discussed. We conclude with a discussion of limitations and future research directions.     

Smiling and sad wrinkles: Age-related changes in the face and the perception of emotions and intentions

There is a common belief that wrinkles in the aging face reflect frequently experienced emotions and hence resemble these affective displays. This implies that the wrinkles and folds in elderly faces interfere with the perception of other emotions currently experienced by the elderly as well as with the inferences perceivers draw from these expressions. Whereas there is ample research on the impact of aging on emotion recognition, almost no research has focused on how emotions expressed by the elderly are perceived by others. The present research addresses this latter question. Young participants rated the emotion expressions and behavioral intentions of old and young faces displaying identical expressions. The findings suggest that emotions shown on older faces have reduced signal clarity and may consequently have less impact on inferences regarding behavioral intentions. Both effects can be expected to have negative consequences for rapport achieved in everyday interactions involving the elderly.     

Emotion in the neutral face: a mechanism for impression formation?

The current work examined contributions of emotion-resembling facial cues to impression formation. There exist common facial cues that make people look emotional, male or female, and from which we derive personality inferences. We first conducted a Pilot Study to assess these effects. We found that neutral female versus neutral male faces were rated as more submissive, affiliative, na?ve, honest, cooperative, babyish, fearful, happy, and less angry than neutral male faces. In our Primary Study, we then "warped" these same neutral faces over their corresponding anger and fear displays so the resultant facial appearance cues now structurally resembled emotion while retaining a neutral visage (e.g., no wrinkles, furrows, creases, etc.). The gender effects found in the Pilot Study were replicated in the Primary Study, suggesting clear stereotype-driven impressions. Critically, ratings of the neutral-over-fear warps versus neutral-over-anger warps also revealed a profile similar to the gender-based ratings, revealing perceptually driven impressions directly attributable to emotion overgeneralisation.     

Cognitive Processing Therapy Versus Supportive Counseling for Acute Stress Disorder Following Assault: A Randomized Pilot Trial

The study tested the efficacy and tolerability of cognitive processing therapy (CPT) for survivors of assault with acute stress disorder. Participants (N = 30) were randomly allocated to CPT or supportive counseling. Therapy comprised six individual weekly sessions of 90-min duration. Independent diagnostic assessment for PTSD was conducted at posttreatment. Participants completed self-report measures of posttraumatic stress, depression, and negative trauma-related beliefs at pre-, posttreatment, and 6-month follow-up. Results indicated that both interventions were successful in reducing symptoms at posttreatment with no statistical difference between the two; within and between-group effect sizes and the proportion of participants not meeting PTSD criteria was greater in CPT. Treatment gains were maintained for both groups at 6-month follow-up.     

A Longitudinal Examination of Overgeneral Memory and Psychopathology in Children Following Recent Trauma Exposure

This study represents the first longitudinal examination of the trajectory of overgeneral memory (OGM) in children and how this relates to psychopathology immediately after trauma exposure. We recruited fifty 7‐ to 17‐year‐olds who had experienced an accidental injury that resulted in hospital admission. Assessment of psychological symptoms, OGM and cognitive processes proposed to drive OGM was completed at three points over a 6‐month period post‐trauma. We found that OGM was not related to depressive symptoms and that time since trauma exposure moderated the relationship between post‐traumatic stress disorder symptoms and OGM. Although no relationship was found in the first 3 months following trauma, OGM was protective against post‐traumatic stress disorder symptoms at 6 months post‐trauma. Despite models of OGM (e.g. Williams et al., 2007 ) emphasising the role of rumination and executive control in explaining OGM, we found no evidence that they were related to OGM.

A Two-Phase Approach to Developing SNAP: an iPhone Application to Support Appointment Scheduling and Management for Women with a <Emphasis Type="Italic">BRCA</Emphasis> Mutation

Professional organizations provide surveillance guidelines for BRCA1 and BRCA2 (BRCA) carriers with intact breasts and/or ovaries to facilitate early cancer detection. However, literature indicates adherence to surveillance guidelines is inconsistent at best. Using the Messaging Model for Health Communication Campaigns framework, we undertook a two-phase formative research approach to develop an intervention to promote adherence to surveillance guidelines. Discussion groups identified preferred intervention format and function in phase I. Findings indicated carriers desired a phone application (app) to assist with surveillance management and appointment tracking. Thus, an iPhone app for carriers to track appointments based on published surveillance guidelines was developed. In phase II, we obtained feedback from BRCA carriers via a survey during a prototype demonstration at a regional conference. Participants in phase II wanted reminder capabilities and the ability to add and modify information fields. This feedback informed intervention modifications, resulting in the Scheduling Necessary Advised Procedures (SNAP) iPhone app currently being pilot tested by BRCA carriers throughout the USA.     

Cognitive load of navigating without vision when guided by virtual sound versus spatial language

A vibrotactile N-back task was used to generate cognitive load while participants were guided along virtual paths without vision. As participants stepped in place, they moved along a virtual path of linear segments. Information was provided en route about the direction of the next turning point, by spatial language ("left," "right," or "straight") or virtual sound (i.e., the perceived azimuth of the sound indicated the target direction). The authors hypothesized that virtual sound, being processed at direct perceptual levels, would have lower load than even simple language commands, which require cognitive mediation. As predicted, whereas the guidance modes did not differ significantly in the no-load condition, participants showed shorter distance traveled and less time to complete a path when performing the N-back task while navigating with virtual sound as guidance. Virtual sound also produced better N-back performance than spatial language. By indicating the superiority of virtual sound for guidance when cognitive load is present, as is characteristic of everyday navigation, these results have implications for guidance systems for the visually impaired and others.     

Emotional expressions forecast approach-avoidance behavior

The contention that basic behavioral intentions are forecasted by emotional expressions has received surprisingly little empirical support. We introduce a behavioral task that gauges the speed with which movement of angry and fearful faces (toward or away from an expressor's gaze) are accurately detected. In two studies we found that perceivers were faster to correctly detect approaching anger faces (i.e., faces that moved in the direction of their own gaze). The opposite, however, was not true for fear expressions. These findings offer evidence that, at least for anger displays, the basic behavioral intent to approach is strongly transmitted and at very low-levels of processing, even priming congruent behavioral responses in observers. The null results for fear faces may indicate that these signal a “freezing” response or behavioral inhibition rather than flight per se. The results of this work are discussed in relation to contemporary theories of emotion.
