Trust amply recompensed: psychological research at Weyburn, Saskatchewan, 1957-1961

During the 1950s and 1960s professionals intensely debated the prospect of changes in the mental health system, largely as a result of the introduction of new therapies, revised theories of mental disorder, and shifting policies governing mental health accommodation. As well as giving rise to new subspecialties within medicine, psychiatrists in some jurisdictions at this time worked closely with psychologists in an attempt to offer a more comprehensive set of options that merged theory with practice. In Saskatchewan, mental health professionals worked closely with government officials and bureaucrats and produced a variety of innovative strategies that addressed changing priorities in this system. This article examines the role played by psychologists in Saskatchewan during this period as they worked cooperatively with psychiatrists and bureaucrats to merge medical, psychological, and political perspectives in a system aimed at accommodating mental illness in the wake of new theories and treatments that questioned the efficacy of care in institutionalized settings in the wake of growing suggestions for care in the community.     

Upper-left gaze bias reveals competing search strategies in a reverse Stroop task

Three experiments with a total of 87 human observers revealed an upper-left spatial bias in the initial movement of gaze during visual search. The bias was present whether or not the explicit control of gaze was required for the task. This bias may be part of a search strategy that competed with the fixed-gaze parallel search strategy hypothesized by Durgin [Durgin, F. H. (2003). Translation and competition among internal representations in a reverse Stroop effect. Perception &Psychophysics, 65, 367-378.] for this task. When the spatial probabilities of the search target were manipulated either in accord with or in opposition to the existing upper-left bias, two orthogonal factors of interference in the latency data were differentially affected. The two factors corresponded to two different forms of representation and search. Target probabilities consistent with the gaze bias encouraged opportunistic serial search (including gaze shifts), while symmetrically opposing target probabilities produced latency patterns more consistent with parallel search based on a sensory code.     

Working memory and inhibition across the adult life-span

Research has shown that age-related changes in cognitive performance are due mostly to the decline of general factors such as working memory and inhibition. The present study is aimed at investigating age-related changes in these mechanisms across the adult life-span from 20 to 86 years of age. Results indicate a linear relationship between each working memory measure and age, independently of the nature of the task, and a quadratic relationship between the single inhibitory measures and age. Moreover, hierarchical regression analyses show that inhibition accounts for a significant, but modest, part of the age-related variance in working memory. Taken together, these results suggest that inhibition is not as crucial a contributor of age-related changes in the functional capacity of working memory across the adult life-span as previously thought.     

Praying with those who might forget: pastoral considerations with memory impairment

This article gives an account of a person who had memory impairment and received pastoral care, with an emphasis on pastoral needs and prayer. The author provides a first-hand account addressing both sides of the pastoral care interaction. She experienced years of memory impairment comparable to mild to moderate Alzheimer's Disease. Now, however, she is a seminarian. She provides a detailed account of pastoral care received during the time of memory impairment and considers both the visiting pastor's intent and the author's recollection of the prayer and pastoral care received. Part of the uniqueness of this account is that persons with memory impairment do not usually regain their cognitive functioning and then also obtain pastoral education from which to provide the guidance gained as both patient and pastor.     

Stimulus presentation versus stimulus removal in the Good Behavior Game

The Good Behavior Game (GBG) is an effective intervention to reduce disruptive behavior. The GBG typically involves immediate stimulus presentation (e.g.., delivery of a token) following disruptions; however, experimenters have also removed tokens contingent upon disruptions. In the present study, we compared the effects of the GBG-stimulus presentation (P) and GBG-stimulus removal (R) on levels of disruptions in a 2nd-grade general education classroom. In addition, we measured student prompts, teacher praise and correctives, and student and teacher preference. The GBG-P and GBG-R versions of the game were similarly effective in reducing disruptions. However, the teacher chose to implement the GBG-R and the majority of students reported a preference for the GBG-R.     

The Impact of Contextual Self‐Ratings and Observer Ratings of Personality on the Personality–Performance Relationship1

This study examined 2 possible ways of increasing the predictive validity of personality measures: using observer (i.e., supervisor and coworker) ratings and work‐specific self‐ratings of Big Five personality factors. Results indicated that among general self‐ratings of Big Five personality dimensions, Conscientiousness was the best predictor of in‐role performance, and Agreeableness and Emotional Stability were the best predictors of organizational citizenship behavior (OCB). Observer ratings of personality accounted for incremental variance in job performance (in‐role performance and OCB) beyond that accounted for by general self‐ratings. However, contrary to our expectations, work‐specific (i.e., contextual) self‐ratings of personality generally did not account for incremental variance in job performance beyond that accounted for by general self‐ratings.     

Pubertal development and behavior: Hormonal activation of social and motivational tendencies

Adolescence is a time of dramatic changes including rapid physical growth, the onset of sexual maturation, the activation of new drives and motivations, and a wide array of social and affective changes and challenges. This review focuses on behavioral changes in this interval and is organized by the claim that a key set of these adolescent changes are part of a more general re-orientation of social behavior. More specifically we hypothesize that pubertal maturation is associated with the activation of social and motivational tendencies, which in turn influence behavior and emotion in adolescence depending upon interactions with social context. We focus on evidence for two examples of these motivational changes: (1) increases in sensation-seeking (motivational tendency to want to experience high-intensity, exciting experiences) and (2) stronger natural interest in—and pursuit of—contact with peers and potential romantic partners. We consider how these motivational changes contribute to the broader social re-orientation of adolescence, including exploration of social experiences, development of skills and knowledge relevant to taking on adult social roles, individuation from family, and establishment of an individual identity, all of which represent core developmental tasks during this period in the life span ( 9, 16 and 62). The paper also emphasizes the importance of investigating and understanding the direct influences of puberty on behavior and disentangling these from the broader set of changes during adolescent development.     

Working memory training in older adults: evidence of transfer and maintenance effects

Few studies have examined working memory (WM) training-related gains and their transfer and maintenance effects in older adults. This present research investigates the efficacy of a verbal WM training program in adults aged 65-75 years, considering specific training gains on a verbal WM (criterion) task as well as transfer effects on measures of visuospatial WM, short-term memory, inhibition, processing speed, and fluid intelligence. Maintenance of training benefits was evaluated at 8-month follow-up. Trained older adults showed higher performance than did controls on the criterion task and maintained this benefit after 8 months. Substantial general transfer effects were found for the trained group, but not for the control one. Transfer maintenance gains were found at follow-up, but only for fluid intelligence and processing speed tasks. The results are discussed in terms of cognitive plasticity in older adults.
