How much and how fast: rapid processing of spoken language in later adulthood

Speech processing involves rapid decoding and construction of meaning from a transitory acoustic signal. Because older adults have been found to be slower in performing many cognitive tasks, we hypothesized that they may have difficulty in immediate recall for speech of increasing input rate. Two experiments are reported in which both older and younger participants listened to and immediately recalled sentences that were systematically varied in speech rate and number of propositions. Although recall performance of the older adults showed a disproportionate decline when speech rate was increased, older adults, as well as the younger adults, were able to recall sentences of increasing propositional densities. We also found that the tendency to recall a greater proportion of main ideas than details (the levels effect) was enhanced by increased propositional density, and depressed by increased speech rate and increased age. These results are discussed in terms of an age-related change in the rate at which information can be processed in working memory.     

Instructed versus pharmacological effects of alcohol in alcoholics and social drinkers

Twelve alcoholics and 12 social drinkers were studied in an experiment where instructions about alcohol or placebo were orthogonally crossed with administration of alcohol or placebo in a Balanced Placebo Design. Three subjects were simultaneously observed while watching soccer games on the TV together and having free access to a mixed drink, which in the alcohol conditions contained 150ml of 80% proof vodka. The assessment procedure included several aspects of drinking behavior, behavioral observations during the session, psychiatric ratings and nurse observations before and after each session, ratings for craving, self-reported state anxiety and physiological changes (heart rate and blood pressure). In general, the results showed the alcoholic's behavior to be controlled by instruction-induced expectancies rather than by the actual beverage given, whereas the social drinkers showed tendencies in the opposite direction. The implications of these results for the traditional disease conception of alcoholism and for learning theory approaches are discussed.     

The effect of sensitization and coping style on post-traumatic stress symptoms and quality of life: two longitudinal studies

The present study investigated the effects of multiple trauma exposure and coping style on post-traumatic stress symptoms and quality of life. It was hypothesized that sensitization would occur in subjects repeatedly exposed to life-threatening situations (study 1), and different coping styles would act as a resilience or facilitating factor in symptom development (study 2). The results showed that the single-exposure group revealed a decrease in trauma specific stress reactions from three weeks to four months, with a persistent reduction at 12-month follow-up, while the repeated-exposure group showed an increase in symptom reporting over the 12-month period. The same pattern emerged for perceived quality of life-measured by the General Health Questionnaire (GHQ-30). The second study revealed a correlation between scores on avoidant-focused coping style and the Impact of Event Scale-avoidance dimension, Post-traumatic Symptom Scale and GHQ-30. Furthermore, only subjects with a dominant coping style of emotion-focused or task-focused coping showed a reduction in trauma-specific symptom scores over time.     

Towers of Hanoi and London: contribution of working memory and inhibition to performance

The Tower of Hanoi and Tower of London have become well-established executive function tasks that presumably tap cognitive skills mediated by the frontal cortex. It has been assumed that the two tower tasks are more or less interchangeable and that both measure working memory and inhibition processes. These assumptions were tested in a study involving 37 normal college volunteers (M age = 20 years). Participants were administered the Tower of Hanoi (TOH), Tower of London-Revised (TOL-R), two working memory tests, and two tests of inhibition. The two tower tasks correlated significantly (r = .39), but only moderately. The working memory and inhibition variables explained over one-half of the variance in TOL-R performance; however, there was a relatively weaker contribution of inhibition to TOH performance.     

Zones of Proximal Emotional Development — Psychotherapy Within a Neuroaffective Perspective

This article outlines a conceptual framework for assessing personal and emotional functions of a person’s zone of proximal emotional development. The framework is based on the integrative theory Neuroaffective Developmental Psychology (NADP), which brings together attachment theory, neuropsychology, developmental psychology, and trauma theory. Within the NADP framework, this article describes a way of understanding children’s normal emotional mental organization and of examining how this mental organization may be developed or disturbed by relational issues. It also describes how a child’s mental organization can be disturbed and thus, without intervention, disturb the child’s personality development on a lifelong basis. The article presents three case vignettes, describing three children growing into adolescence with three different attachment patterns and suggested individually tailored intervention plans for each of them, relevant and useful for clinicians working with vulnerable children and families. Because the nervous system retains its plasticity throughout life, attachment is not necessarily an unchangeable pattern. That is why we as clinicians should develop psychotherapeutic methods and a research-based way of determining “what works for whom” by assessing the zone of individual proximal emotional development. The text outlines the characteristics of NADP and how it can be used to structure an intervention plan.     

Performance Management at the Wheel: Driving Employee Engagement in Organizations

Based on a study conducted in a large corporation (XINC, a pseudonym) and other research, it appears that performance management can be used to increase levels of employee engagement. We begin this article with a discussion of employee engagement, define engaged employees as those who feel involved, committed, passionate, and empowered, and demonstrate those feelings in work behavior. We then discuss an expanded view of performance management, conceptualizing it as five major activities that serve to organize relevant behaviors shown to be either direct or indirect predictors of employee engagement in the study at XINC. These major activities include setting performance and development goals, providing ongoing feedback and recognition, managing employee development, conducting mid-year and year-end appraisals, and building a climate of trust and empowerment. In turn, we briefly discuss how each of these major activities contributes to employee engagement, suggest which activities benefit from further research, and recommend possible studies. Although there is evidence for performance management as a driver of employee engagement, we conclude there is a need for additional research that clarifies for managers which of these activities have the strongest impact on employee engagement.
