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.     

Maternal Depression and Child Psychopathology: A Meta-Analytic Review

Although the association between maternal depression and adverse child outcomes is well established, the strength of the association, the breadth or specificity of the outcomes, and the role of moderators are not known. This information is essential to inform not only models of risk but also the design of preventive interventions by helping to identify subgroups at greater risk than others and to elucidate potential mechanisms as targets of interventions. A meta-analysis of 193 studies was conducted to examine the strength of the association between mothers’ depression and children’s behavioral problems or emotional functioning. Maternal depression was significantly related to higher levels of internalizing, externalizing, and general psychopathology and negative affect/behavior and to lower levels of positive affect/behavior, with all associations small in magnitude. These associations were significantly moderated by theoretically and methodologically relevant variables, with patterns of moderation found to vary somewhat with each child outcome. Results are interpreted in terms of implications for theoretical models that move beyond main effects models in order to more accurately identify which children of depressed mothers are more or less at risk for specific outcomes.     

Modeling effects of rhythmic context on perceived duration: a comparison of interval and entrainment approaches to short-interval timing

Relative merits of interval and entrainment conceptions of the internal clock were assessed within a common theoretical framework by 4 time-judgment experiments. The timing of tone onsets marking the beginning and ending of standard and comparison time intervals relative to a context rhythm were manipulated: onsets were on time, early, or late relative to the implied rhythm, and 2 distinct accuracy patterns emerged. A quadratic ending profile indicated best performance when the standard ended on time and worst performance when it was early or late, whereas a flat beginning profile (Experiments 1-3) indicated uniform performance for the 3 expectancy conditions. Only in Experiment 4, in which deviations from expected onset times were large, did significant effects of beginning times appear in time-discrimination thresholds and points of subjective equality. Findings are discussed in the context of theoretical assumptions about clock resetting, the representation of time, and independence of successive time intervals.     

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.     

Myths and misconceptions about hypnosis and suggestion: Separating fact and fiction

We present 21 prominent myths and misconceptions about hypnosis in order to promulgate accurate information and to highlight questions for future research. We argue that these myths and misconceptions have (a) fostered a skewed and stereotyped view of hypnosis among the lay public, (b) discouraged participant involvement in potentially helpful hypnotic interventions, and (c) impeded the exploration and application of hypnosis in scientific and practitioner communities. Myths reviewed span the view that hypnosis produces a trance or special state of consciousness and allied myths on topics related to hypnotic interventions; hypnotic responsiveness and the modification of hypnotic suggestibility; inducing hypnosis; and hypnosis and memory, awareness, and the experience of nonvolition. By demarcating myth from mystery and fact from fiction, and by highlighting what is known as well as what remains to be discovered, the science and practice of hypnosis can be advanced and grounded on a firmer empirical footing.     

Dissociative alterations in body image among individuals reporting out-of-body experiences: a conceptual replication

A conceptual replication of the link between self-reported dissociative alterations in body-image under experimental conditions and the reporting of prior out-of-body experiences in a recent data set was undertaken. Also examined was whether this relationship would hold for experiences reported during the experimental context and whether it is independent of self-reported New Age belief. Data from mostly undergraduates (N= 40; M age = 33.5, SD = 12.5; 27 women) in a mirror-gazing study were retrospectively analyzed. The 9 individuals who reported prior out-of-body experiences, relative to those 31 who did not, exhibited significantly greater self-reported dissociative alterations in body-image during the mirror-gazing task, even when the influence of scores on New Age belief was controlled for statistically. The same differential relationship was not found between 6 individuals who did and 34 who did not report out-of-body experiences during the task.
