Recognition and discrimination of emotional faces and pictures

In order to learn whether patients with right-hemisphere disease (RHD) had a deficit in their ability to discriminate and comprehend emotional faces and pictures, we studied nine patients with RHD, nine patients with left-hemisphere disease (LHD), and nine controls. The subjects were presented with six picture tests that comprised either emotional faces or emotional scenes. Their task was either to denote (name or choose) an emotion or to discriminate (same, different) between two faces or emotions. Patients with RHD performed significantly worse than subjects with LHD when asked to discriminate between faces, to discriminate between emotional faces, and to name emotional scenes. There was also a trend for the RHD group to be more impaired than the LHD group when asked to name the emotional face or choose the emotional face. Except for the facial and emotional discrimination tests, the LHD patients also performed worse than controls.     

Visuospatial competency, handedness, and cerebral dominance

The present study addressed the question of Levy's (1974, Psychobiological implications of bilateral assymetry. In S. Dimond &; J. G. Beaumont, Hemispheric function in the human brain, NY: Halstead. Pp. 121–183.) proposal that left handers would have lowered spatial skills relative to verbal skills. In the first part of the study, performance on the PMA (visuospatial subtest) and WAIS Block Design subtest were compared between right and left handed high school and college samples. No support could be found for deficient visuo-spatial performance in the left handers. In the second part of the experiment, no relative impairment of visuospatial skills was found when subjects were classified into predicted speech dominance groups on the basis of a dichotic listening task and/or a visual half-field task. An extreme groups comparison of the most left dominant and most right dominant groups again yielded no significant differences in visuo-spatial performance. Finally, the relationship between degree of speech lateralization and visuo-spatial skills was examined. Only partial support for differences in cerebral organization for speech in left handers was found in the college sample.     

Impact of automation on aircrew communication and decision-making performance

Increasing levels of automation are being introduced into the cockpit. Yet, it is difficult to predict the impact of these automatic systems on other elements of flight, such as crew communication and the ability to arrive at an effective decision. This study attempted to clarify the relation among these variables. Forty-eight pilots were assigned to two-person crews and asked to fly a simulated mission in either automated or manual conditions using a low-fidelity simulator. The scenario was designed to require crewmembers to arrive at a collective decision based on information obtained about an evolving simulated disaster. The results indicated that the introduction of automation was not associated with better performance. However, several significant differences were observed in the communications of crews flying in the automated versus manual conditions. The results are discussed in terms of their implications for communications training for advanced technology aircraft.

The Role of Social–Emotional Mediators on Middle School Students’ Academic Growth as Fostered by an Evidence‐Based Intervention

The authors describe a school counselor intervention delivered to a predominantly Hispanic group of 193 7th‐grade students. Using multilevel modeling, the authors found that participation resulted in greater rates of academic achievement, particularly in math and for students who pretested at lower achievement levels. Results indicated an indirect effect on math achievement for the executive functioning constructs of plan and organize and task completion, but no executive functioning mediators were found for reading or feelings of connectedness.     

Connecting Opportunity and Strain to Understand Deviant Behavior: A Test of General Strain Theory

This study examined the connection of general strain theory to opportunity, as defined by one’s desire and ability to engage in criminal or deviant behavior. Over 1,000 undergraduate students completed the electronic survey with a response rate of 12.85%. Regression analyses showed removal of positive stimuli predicted deviant behavior in all models, but anger and other affective states were significant only in some models. Peer deviance, social bonds, and opportunity were important significant predictors. This study supports Agnew’s assertions that strain theory works in conjunction with social learning, social control, and, per this study, opportunity theories.
