Bipolar disorder and family communication: effects of a psychoeducational treatment program

Family psychoeducational programs are efficacious adjuncts to pharmacotherapy for patients with schizophrenic and bipolar disorders, but little is known about what these programs change about families. The authors assessed changes in face-to-face interactional behavior over 1 year among families of bipolar patients who received a 9-month family-focused psychoeducational therapy (FFT; n = 22) or crisis management with naturalistic follow-up (CMNF; n = 22), both administered with maintenance pharmacotherapy. Members of families who received FFT showed more positive nonverbal interactional behavior during a 1-year posttreatment problem-solving assessment than families who received CMNF, although no corresponding decreases were seen in negative interactional behaviors. The positive effect of family treatment on patients' symptom trajectories over 1 year was partially mediated by increases in patients' positive nonverbal interactional behaviors during this same interval.     

On the nature of international sales and sales management research: a social network–analytic perspective

This research uses a combination of text mining, co-word analysis, and social network analysis (SNA) to review 132 international sales and sales management (ISSM) articles published between 1980 and 2017. The study provides a unique view of the past and future of ISSM research and provides three principal contributions. First, from a social network–analytic perspective, it offers a unique examination of the ways ISSM research topics are interconnected, as reflected by keyword network structure. Second, by conducting SNA across two periods (1980–1999 and 2000–2017) and examining the changes in network centrality measures, the study offers initial insights into the evolving nature of the ISSM literature. Third, the study reports keyword network disconnections (i.e., structural holes) to propose a fruitful agenda for future ISSM research. Taken together, this research offers a current perspective of the ISSM research domain's evolving nature.     

Distracted by distractors: eye movements in a dynamic inattentional blindness task

Inattentional Blindness (IB) occurs when observers engaged in resource-consuming tasks fail to see unexpected stimuli that appear in their visual field. Eye movements were recorded in a dynamic IB task where participants tracked targets amongst distractors. During the task, an unexpected stimulus crossed the screen for several seconds. Individuals who failed to report the unexpected stimulus were deemed to be IB. Being IB was associated with making more fixations and longer gaze times on distractor stimuli, being less likely to fixate the unexpected stimulus, and having lower working memory capacity than those who were not IB. Noticing the unexpected stimulus was not contingent upon fixating it, suggesting that some individuals processed the unexpected stimulus via covert attention. The findings support earlier research on working memory and IB. In addition, IBs were less efficient attentional allocators than those who were not IB, as reflected in their eye tracking of irrelevant distractors.     

The attentional processes underlying impaired inhibition of threat in anxiety: the remote distractor effect

The current study explored the proposition that anxiety is associated with impaired inhibition of threat. Using a modified version of the remote distractor paradigm, we considered whether this impairment is related to attentional capture by threat, difficulties disengaging from threat presented within foveal vision, or difficulties orienting to task-relevant stimuli when threat is present in central, parafoveal and peripheral locations in the visual field. Participants were asked to direct their eyes towards and identify a target in the presence and absence of a distractor (an angry, happy or neutral face). Trait anxiety was associated with a delay in initiating eye movements to the target in the presence of central, parafoveal and peripheral threatening distractors. These findings suggest that elevated anxiety is linked to difficulties inhibiting task-irrelevant threat presented across a broad region of the visual field.     

The effect of cognitive behavior therapy on decision making in adolescents who self-harm: a pilot study

Research shows poor decision making in adolescents who self-harm and a positive correlation between decision-making abilities and duration since last self-harm episode. This exploratory study investigated whether decision making in self-harming adolescents could be improved through treatment with a novel cognitive behavior therapy (CBT). It also investigated whether improvement in decision making following treatment was linked to self-harm cessation. Adolescent self-harmers receiving CBT (n = 24) or no treatment (n = 9) and healthy controls (n = 22) were longitudinally compared on the Iowa gambling task (IGT). Significant IGT improvements were only observed for adolescents who self-harm following CBT. CBT may benefit adolescent self-harmers and generate decision-making improvements.     

Reliability of upper extremity kinematics while performing different tasks in individuals with stroke

Assessments of upper extremity performance typically include qualitative rather than quantitative measures of functional ability. Kinematic analysis is an objective, discriminative measure that quantifies movement biomechanics; however, the use within the poststroke impaired upper extremity is not well established. The purpose of this study was to examine the reliability of upper extremity kinematics in 18 individuals with stroke and 9 healthy controls. Participants performed reaching and grasping tasks over 2 separate days and metrics included movement time, peak velocity, index of curvature, trunk displacement, maximum aperture, and percentage of the movement cycle where maximum aperture occurred. The results showed moderate to high intraclass correlation and low standard error of measurement values for most variables, demonstrating that kinematic analysis may be a feasible and useful tool to quantify upper extremity movement after stroke.     

The Role of Neighborhood in the Development of Aggression in Urban African American Youth: A Multilevel Analysis

The purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low‐income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.     

Anxiety and sensitivity to eye gaze in emotional faces

This paper reports three studies in which stronger orienting to perceived eye gaze direction was revealed when observers viewed faces showing fearful or angry, compared with happy or neutral, emotional expressions. Gaze-related spatial cueing effects to laterally presented fearful faces and centrally presented angry faces were also modulated by the anxiety level of participants, with high- but not low-state anxious individuals revealing enhanced shifts of attention. In contrast, both high- and low-state anxious individuals demonstrated enhanced orienting to averted gaze when viewing laterally presented angry faces. These results provide novel evidence for the rapid integration of facial expression and gaze direction information, and for the regulation of gaze-cued attention by both the emotion conveyed in the perceived face and the degree of anxiety experienced by the observer.
