Observational Learning in Pigeons: The effects of Model Proficiency on Observer Performance

Observational learning of a successive visual discrimination problem by pigeons was studied using conspecifics as models performing at proficient or at nonproficient levels. During the observational period, observers were confined without response opportunity and were subsequently trained in the model's discriminative task. Significantly better performance in subsequent learning was found for observers of nonproficient models. In contrast, no significant differences in learning of the visual discrimination task were found between pigeons that observed proficient models and pigeons that had undergone only confinement in the observation apparatus or those trained without prior observation or confinement experience. The apparent paradox of less proficient models producing better learners may be related to the consequences of observing additional negative-stimulus responding per se or to observation of models' behavior changing from less proficient to more proficient with consequent improvement in reinforcement opportunity.     

Trainee Perceptions of Drill Sergeant Qualities During Basic Combat Training

Basic combat training plays an important role in military service with approximately 72,000 soldiers participating in the United States annually. Although Drill Sergeant qualities have been widely portrayed in popular media, there is very little empirical research that documents the characteristics of Drill Sergeants and the impact these characteristics may have on trainees. In this study we evaluated a measure of perceived Drill Sergeant qualities and the degree to which these qualities related to mental health symptoms and job-related outcomes of trainees. Three types of perceived Drill Sergeant qualities were found from factor analyses: motivation, respect, and toughness. Using latent growth curve analyses, higher initial scores on motivation and respect, but not toughness, were associated with greater decreases in mental health symptoms over time. Further, changes in perceived Drill Sergeant qualities related to changes in depressive symptoms, unit cohesion, and citizen behaviors assessed over the course of basic combat training.     

Differential Reinforcement of Alternative Behavior in Center-Based Classrooms: Evaluation of Pre-teaching the Alternative Behavior

This study investigated the effectiveness of a differential reinforcement of alternative behavior procedure in decreasing disruptive behavior while simultaneously increasing the appropriate behavior of four children of typical development between the ages of 4 and 6 in center-based classrooms. We began with brief functional analyses for each child. Then, differential reinforcement procedures, with and without pre-teaching the alternative behavior, were compared using an alternating treatments design. Results indicated that the differential reinforcement procedure with pre-teaching resulted in lower levels of problem behavior and greater levels of the alternative behavior compared to differential reinforcement alone. Results are discussed in terms of implications for applied practice and functional assessment and intervention research.     

Male Veterans' Perceptions of Midlife Career Transition and Life Satisfaction: A Study of Military Men Transitioning to the Teaching Profession

Members of Troops to Teachers (N = 102 male veterans) were surveyed regarding their career transition experiences and life satisfaction. Primary themes related to career transition included preparation for transition, investment vs. sacrifice, and rewards of new career. Primary themes related to life satisfaction included helping and serving others, accomplishment, and contentment vs. struggle.     

Self-Portraits: Possible Selves in European-American,Chilean, Japanese and Japanese-American Cultural Contexts

Possible selves of students from European-American (EA), Chilean (CH), Japanese-American (JA), and Japanese (JN) cultural contexts were analyzed, revealing differences in the emphasis given to various content themes. EA possible selves focus on intrapersonal themes (i.e., “fear being dependent”), consistent with cultural emphases on uniqueness and independent development. In JN, JA and CH contexts, career and education themes dominate possible selves, consistent with particularly strong cultural emphasis on professional and academic accomplishments. The cultural contexts also differ in their predominant configurations of possible selves—EA and CH possible selves often show balance (expected and feared selves of similar theme but opposing valence, i.e., “expect to graduate from college” and “fear dropping out of college”) while JN and JA selves more frequently match (expected and feared selves of similar thematic content and valence, i.e., “expect to be idle” and “fear being idle”).
