How serious are expressions of protected values?

People think that some things that they value should be protected from trade-offs with other things. For example, people think that no economic gain is great enough to justify clear-cutting old-growth forest. The authors probed the stability of these protected values (PVs) in several ways. Subjects were asked to think of counterexamples, and this had some effect on PVs. Subjects were then asked how they would resolve conflicts between 2 PVs. Resolutions did not differ from those between other values, but subjects tended to feel that conflicts between PVs did not occur in reality. Despite people's claims that PVs are unchanged by variation in quantity, expression of PVs was reduced when the magnitude or probability of the violation of a PV was smaller. In summary, PVs appear to be labile and amenable to challenge. Despite earlier concerns, apparent PVs may not always preclude the use of valuation measures in cost-effectiveness analysis or negotiated agreement on controversial issues.     

The development of implicit attitudes. Evidence of race evaluations from ages 6 and 10 and adulthood

To understand the origin and development of implicit attitudes, we measured race attitudes in White American 6-year-olds, 10-year-olds, and adults by first developing a child-oriented version of the Implicit Association Test (Child IAT). Remarkably, implicit pro-White/anti-Black bias was evident even in the youngest group, with self-reported attitudes revealing bias in the same direction. In 10-year-olds and adults, the same magnitude of implicit race bias was observed, although self-reported race attitudes became substantially less biased in older children and vanished entirely in adults, who self-reported equally favorable attitudes toward Whites and Blacks. These data are the first to show an asymmetry in the development of implicit and explicit race attitudes, with explicit attitudes becoming more egalitarian and implicit attitudes remaining stable and favoring the in-group across development. We offer a tentative suggestion that mean levels of implicit and explicit attitudes diverge around age 10.     

The usefulness of coroners' data on suicides for providing information relevant to prevention

Coroners' records are an accessible source of information on suicides. To assess their usefulness in relation to the investigation of specific methods of suicide, we examined coroners' records for 492 suicides across 24 jurisdictions in England. Generally data on demographic variables were well recorded. Information on contact with general practitioner and psychiatric services was less commonly available. Where those who had self-poisoned died in hospital, information on treatment and blood levels of drugs taken were not routinely available. For suicides by hanging, information on the source of ligature was frequently missing. Where firearms were used, information about licensing and storage were not routinely recorded. Generally there was wide variation across coroners in information relevant to specific methods. The use of standardized forms by coroners would assist studies of factors associated with suicide and potentially provide a representative source of information relevant to suicide prevention.     

The strategic control of multiple routes in imitation of actions

The aim of this study was to bring to the surface the strategic use of imitative processes in the context of a 2-route model: (a) direct imitation, used in reproducing new, meaningless actions, and (b) imitation based on stored semantic knowledge of familiar meaningful actions. Three experiments were carried out with healthy participants who reproduced meaningful and meaningless actions within an established time limit. The study investigated 3 factors that could potentially affect the selection of processes used for imitation: (a) the composition of the experimental list (blocked or mixed presentation), (b) the presence-absence of instructions (Experiments 1 and 2), and (c) the relative proportions of the stimuli (Experiment 3). Overall, the results suggest that each of these factors influences the selection of imitative strategies in healthy individuals with temporarily reduced capacities, as happens in the case of brain-damaged patients.     

Amygdala responses to emotionally valenced stimuli in older and younger adults

Abstract— As they age, adults experience less negative emotion, come to pay less attention to negative than to positive emotional stimuli, and become less likely to remember negative than positive emotional materials. This profile of findings suggests that, with age, the amygdala may show decreased reactivity to negative information while maintaining or increasing its reactivity to positive information. We used event-related functional magnetic resonance imaging to assess whether amygdala activation in response to positive and negative emotional pictures changes with age. Both older and younger adults showed greater activation in the amygdala for emotional than for neutral pictures; however, for older adults, seeing positive pictures led to greater amygdala activation than seeing negative pictures, whereas this was not the case for younger adults.     

Culture-specific patterns in the prediction of life satisfaction: roles of emotion, relationship quality, and self-esteem

This study was conducted to explore the culture-specific roles of emotion, relationship quality, and self-esteem in determining life satisfaction. It was hypothesized that maintaining good interpersonal relationships would make individuals in collectivistic cultures not only feel good about their lives but also feel better about themselves. Furthermore, two emotion variables--emotional expression and emotion differentiation--were proposed as possible determinants of relationship quality. It was hypothesized that emotional expressiveness would be more important for maintaining good interpersonal relationships in individualistic societies but emotion differentiation would be more important in collectivistic cultures. These hypotheses were tested with Euro-American, Asian American, Korean, and Chinese groups using multigroup analyses in a structural equation model. Results supported all proposed hypotheses and indicated that emotion differentiation contributes to maintaining good interpersonal relationships in collectivistic cultures, which contributes to self-esteem and satisfaction with life.     

Human sensitivity to reinforcement: A comment on Kollins, Newland, and Critchfield's (1997) quantitative literature review

In a quantitative review of human operant experiments, Kollins, Newland, and Critchfield (1997) found that humans are less sensitive to reinforcement contingencies than nonhumans are. Human performances were not as consistent with the matching law, and they were more variable from subject to subject. Some of the variables correlated with reduced human sensitivity were surprising. These included collection of the data under more controlled conditions (laboratory rather than naturalistic settings), and inclusions of discriminative stimuli correlated with alternative sources of reinforcement. We discuss these unexpected findings in the light of criticisms that have been leveled against meta-analytic literature reviews (e.g., the wisdom of grouping studies with widely diverse methods), and we suggest ways of improving future analyses of the behavior-analytic literature.     

Career Movement of Female Employees Holding Lower-Level Positions: An Analysis of the Impact of the Type A Behavior Pattern

This paper examines the role of the Type A behavior pattern (TABP) in predicting several types of career movement of women. In general, TABP and in particular the job involvement facet of TABP, had a strong impact on several types of promotion. Relevant results and implications for future research are discussed.     

Stress-management interventions in the workplace: Stress counselling and stress audits

Within the field of stress-management intervention, there have been substantial disagreements on the 'right' approach. Some argue for counselling and stress-management training, while other argue for more substantive organisational change through stress audits. It is argued that both are important in meeting the needs of individuals and organisations.     

Gender attitudes in children

This study investigated children's gender attitudes as a function of the sex, age, and race of the child as well as a geographical SES factor. Two attitudes were measured: gender pride (attributing positive characteristics to a child of the same sex) and gender prejudice (attributing negative characteristics to a child of the other sex). Results indicated that all children tended to select children of the same sex for the positive attributes, but that both boys and girls selected boys for the negative attributes. Although all sex pride scores decreased with age, this effect was most pronounced for girls from an upper-lower-class urban environment.The write-up of this article was supported by our current National Institute of Mental Health Grant No. 1R01MH29417-01, Principal Investigator, Dr. Phyllis A.
