Better Candidates Fly Fewer Training Hours: Another Time Testing Pays Off

The relationship between Pilot Candidate Selection Method (PCSM) scores and the number of flying training hours required to complete United States Air Force Undergraduate Pilot Training (UPT) was investigated on a sample of 1,082 graduates. This was done to demonstrate that ability testing has real world correlates and that cost savings accrued as a result of ability testing. The criterion ‘extra flying hours’ was computed by subtracting each student's cumulative flying hours from the sample mean. The correlations (corrected for range restriction) between PCSM scores and primary and advanced flying training extra hours were ?0.206 and ?0.270, respectively. Demonstrating that UPT graduates with higher PCSM scores required fewer flying hours to complete training facilitates the estimation of the cost avoidance achieved by ability tests.     

Stereoscopic surface interpolation supports lightness constancy

The human visual system has a remarkable ability to construct surface representations from sparse stereoscopic, as well as texture and motion, information. In impoverished displays where few points are used to define regions in depth, the brain often interpolates depth estimates across intervening blank regions to create a compelling sense of a solid surface. The set of experiments described here examined stereoscopic interpolation using a novel technique based on lightness constancy. The effectiveness of this method is notable because it stands as the only technique to date that unequivocally examines the perception of interpolated surfaces, and not surfaces inferred subjectively from depth information in the stimulus. Further, these data support the growing evidence that a primary function of the stereoscopic system is to define three-dimensional surface structure.     

The Program Environment Scale: Assessing Client Perceptions of Community-Based Programs for the Severely Mentally Ill

The Program Environment Scale (PES) was developed for use with clients of community-based programs for the severely mentally ill. It is intended to fill the gap in available tools for assessing clients' perceptions of program functioning as it affects their quality of life in a program. Formal pretests were conducted with 121 clients at 12 randomly selected programs near Washington, DC. The final field test used a revised form (29 domains; 129 items) with 221 clients in 22 programs selected randomly throughout the U.S., including Clubhouse, day treatment, psychosocial rehabilitation, and social club programs. Twenty-three subscales met at least five of eight psychometric criteria for internal consistency and discriminant validity. A 24th subscale was retained because of its substantive importance. Successful subscales cover program atmosphere and interactions (program cares about me, energy level, friendliness, openness, staff-client and client-client respect, reasonable rules, availability of positive physical contact, protection from bad touch, staff investment in their jobs, and confidentiality), client empowerment/staff-client equality (program and treatment empowerment, egalitarian space use), and service components (support for paid work, work importance, emergency access, family activities, housing, public benefits, community activities, medications, substance abuse, and continuity). Subscale validity is indicated by associations of specific service offerings with scores on scales measuring client perceptions of those services, and by an ability to differentiate among program models (i.e., Clubhouses, day treatment programs, and psychosocial rehabilitation programs look different from each other). Subscale scores were not influenced by client characteristics (gender, race, age, diagnosis, number of hospitalizations, length of time in program). The final scale has 97 items and takes about 25 minutes to complete. The PES succeeds in measuring different aspects of programs as clients perceive them. In the programs we visited, directors felt the PES covers the important things they want to know about how clients perceive their program. The PES should become a useful tool both for researchers interested in how client responses to programs may influence their therapeutic outcomes, and for practitioners interested in improving their clients' program experiences and/or increasing convergence of staff and client views of their program.     

The measurement of locus of control in black preschool and primary school children

Developed a form of the Preschool and Primary Nowicki-Strickland locus of control scale (PPNSIE) for use with black children (PPNSIE-B). The psychometric data suggest that the new scale is worthy of further examination and development.     

Personality Predicts Obedience in a Milgram Paradigm

This study investigates how obedience in a Milgram‐like experiment is predicted by interindividual differences. Participants were 35 males and 31 females aged 26–54 from the general population who were contacted by phone 8 months after their participation in a study transposing Milgram's obedience paradigm to the context of a fake television game show. Interviews were presented as opinion polls with no stated ties to the earlier experiment. Personality was assessed by the Big Five Mini‐Markers questionnaire (Saucier, 1994). Political orientation and social activism were also measured. Results confirmed hypotheses that Conscientiousness and Agreeableness would be associated with willingness to administer higher‐intensity electric shocks to a victim. Political orientation and social activism were also related to obedience. Our results provide empirical evidence suggesting that individual differences in personality and political variables matter in the explanation of obedience to authority.     

The disguise of sobriety: unveiled by alcohol in persons with an aggressive personality

This investigation examined the factor structure of 8 well-validated self-report measures that assess traits that fall under the rubric of an "aggressive personality" and then determined how those factor(s) moderated the association between alcohol intoxication and aggression. Participants were 518 (252 men and 266 women) healthy social drinkers between 21 and 35 years of age. Following the consumption of an alcoholic or a placebo beverage, participants were tested on a laboratory aggression paradigm in which electric shocks were received from, and administered to, a fictitious opponent. Aggression was operationalized as the shock intensities and durations administered to the opponent. Results demonstrated a unidimensional factor structure for the aggressive personality traits, which were then combined into a latent variable. The aggressive personality variable moderated the alcohol-aggression relation. Specifically, alcohol was significantly more likely to increase aggression in persons with higher, compared with lower, aggressive personality scores.     

Simple Discrimination Behavior of Young Chimpanzees: Comparisons with Human Aments and Domestic Animals

The authors' purpose in this paper was to examine how the use of the “sad passive” coping style may be related to adolescent self-reported loneliness. Subjects were asked to complete the revised UCLA Loneliness Scale (Russell, Peplau, & Cutrona, 1980) to determine self-reported loneliness and the Coping with Loneliness Questionnaire (CLQ; Rubenstein & Shaver, 1980) in order to examine coping styles. We hypothesized that those adolescents whose coping strategies fell into the category of sad passivity described by Rubenstein and Shaver would indicate greater loneliness than those adolescents whose coping strategies fell into other categories. Results indicated that sad passivity was used by both lonely and nonlonely adolescents, but that nonlonely youngsters resorted to this method only temporarily and in preparation for a more active coping style. Lonely teens, on the other hand, appeared to remain in the sad-passive mode to a maladaptive degree. These results were discussed in terms of their importance for theories of adolescent loneliness and for possible intervention strategies.
