The combined effects of risk and time on choice: Does uncertainty eliminate the immediacy effect? Does delay eliminate the certainty effect?

Researchers have noted parallels between decisions under uncertainty and over time. Three experiments evaluated the theory that uncertainty and time affect choice via a common underlying dimension, such that delaying an outcome is equivalent to making it uncertain. To test this account we asked whether adding uncertainty to outcomes would eliminate the immediacy effect bias. We also asked whether adding time delay to outcomes would eliminate the certainty effect bias. The answer to both questions was yes, provided the prospects were presented singly rather than jointly. In single evaluation uncertainly eliminated the immediacy effect and delay eliminated one form of the certainty effect, while in joint evaluation, these effects did not occur. These findings suggest that at least in some contexts decision makers may equate risk and delay. Other explanations are possible, however, demonstrating that the interaction between risk and delay is complex and not easily understood.     

Dyslexia and visual-spatial talents: compensation vs deficit model

There are both theoretical and empirical reasons to support the hypothesis that dyslexia is associated with enhancement of right-hemisphere, visual-spatial skills. However, the neurological evidence is neutral with respect to whether dyslexic visual-spatial abilities should be superior (a compensation model) or inferior (a deficit model). In three studies we tested the hypothesis that dyslexia is associated with superior visual-spatial skills. Individuals with dyslexia not only failed to show superiority on a range of visual-spatial tasks, even when tasks were presented without time constraints, but also demonstrated a deficit on many tasks. Whereas we found attentional problems associated with dyslexia, these did not explain our findings. Results are discussed in terms of the apparent conflict between the failure to find any visual-spatial talent associated with dyslexia and the fact that dyslexia is overrepresented in certain visual-spatial professions.     

Shame,Ministry, and Theological Education: Leaves from the Notebook of a Defiant Seminarian

Many young adult Christians are highly influenced by relativism of all sorts, which can lead them to a state of doubt. If they voice their doubts too loudly, they are often shamed and abandoned by their elder Christians who do not have (or, perhaps better, do not voice) these doubts. I suggest that those of us involved in youth ministry must meet our youth where they are at, that is, meet them in their doubt, which is not, in my view, a bad place to be. This article focuses on a psychoanalytic understanding of shame and draws from the work of Donald Capps, Erik H. Erikson, Heinz Kohut, and D. W. Winnicott.     

Evidence for a gene-environment interaction in predicting behavioral inhibition in middle childhood

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood.     

Racial discrimination by low-prejudiced whites. Facial movements as implicit measures of attitudes related to behavior

We investigated the relationship of implicit racial prejudice to discriminatory behavior. White university students chose the best of three applicants (two were White and one was Black) for a prestigious teaching fellowship. They then completed the Implicit Association Test (IAT), a measure of implicit racial bias. Three weeks later, participants completed a second implicit measure of racial bias by viewing photos of Whites and Blacks while facial electromyography (EMG) was recorded from sites corresponding to the muscles used in smiling and frowning. Analyses revealed that bias in cheek EMG activity was related to the race of the chosen applicant, whereas bias on the IAT was not. Motivations to control prejudiced reactions were not related to EMG activity or the race of the applicant chosen, but were related to IAT bias. The findings indicate that facial EMG can be used as an implicit measure of prejudice related to discrimination.     

Clinical Perspectives on Neurobiological Effects of Psychological Trauma

Physical trauma to the brain has always been known to affect brain functions and subsequent neurobiological development. Research primarily since the early 1990s has shown that psychological trauma can have detrimental effects on brain function that are not only lasting but that may alter patterns of subsequent neurodevelopment, particularly in children although developmental effects may be seen in adults as well. Childhood trauma produces a diverse range of symptoms and defining the brain's response to trauma and the factors that mediate the body's stress response systems is at the forefront of scientific investigation. This paper reviews the current evidence relating psychological trauma to anatomical and functional changes in the brain and discusses the need for accurate diagnosis and treatment to minimize such effects and to recognize their existence in developing treatment programs.     

An assessment of antecedent events influencing noncompliance in an outpatient clinic

Several studies have shown that various factors can influence noncompliance, including task novelty, rate of presentation, and task preference. This study examined the impact of selected antecedent variables on noncompliance in an outpatient clinic setting. In two experiments involving 6 typically developing children, the consequences for noncompliance remained constant. During Experiment 1, demands that included noncontingent access to adult attention were contrasted with the same demands that did not include attention within a multielement design. In Experiment 2, demands were altered by decreasing the difficulty or amount of work or providing access to attention. In both experiments, results indicated idiosyncratic responses to the manipulated variables, with decreases in noncompliance observed following introduction of one or more antecedent variables with 5 of the 6 participants. These results suggested that noncompliance can be reduced via changes in antecedent variables, including adding potential positive reinforcers to the task situation, and that it is possible to probe variables that alter noncompliance in an outpatient clinic setting.
