Factors associated with Borderline pathology in school-age children

The Diagnostic Interview for Borderlines as revised (DIB-R) for use with children and chart review was completed using the records of 54 children, ages 6 to 12 years, who had been admitted to a public psychiatric hospital. Based on the results of the DIB-R, the children were grouped as borderline and nonborderline. The two groups were then compared with regard to 52 independent variables which have historically been associated with the borderline diagnosis. Stepwise logistic regression was used to identify the cluster of diagnostic and independent variables which best discriminated the borderline subjects. Self-destructive behavior, irritable affect, anhedonia, and an externalizing disorder diagnosis at the time of admission accounted for 95.4% of the borderline children. These findings are in contrast to previous studies which have found an assortment of neuropsychological and/or neurological deficits and stressed the importance of a tendency toward psychotic regression on psychological testing as discriminative variables. The authors underscore the idea that borderline pathology may represent a spectrum of disorders and the need for a more specific psychiatric nosology in describing and diagnosing these children.     

Perceived social context and risk preference: A re-examination of framing effects in a life-death decision problem

This study examines the effects of perceived group context on subjects risk attitudes and their sensitivity to the framing of choice outcomes in a ‘life-death’ decision problem. It seeks to uncover the psychological mechanisms underlying decision-making biases by systematically manipulating the decision context in which the ‘life-death’ problem was described. The study revealed that subjects risk preferences varied as a function of the experimental manipulations. Previously observed reversals in preferences (framing effects) appeared in large-group contexts and disappeared in small-group and family contexts. When considering the fate of small groups, subjects unambiguously favored the probabilistic outcome, no matter how the ‘life-death’ decision problem was framed. The empirical data obtained from the present study suggest that human choice patterns are behaviorally distinguishable across large-group, small-group, and family social contexts.     

Self-focused attention and reactions to conflicting standards

A fundamental postulate of self-awareness theory that has received considerable empirical support is that self-focused attention increases behavioral consistency with “standards of correctness.” This appears to be true whether the standards are internal (such as attitudes or values) or external (e.g., norms). There is some question, however, as to what happens in situations in which an important personal standard conflicts with a salient external standard. Research by E. Diener and T. K. Srull (Journal of Personality and Social Psychology, 1979, 37, 413–423) has suggested that under such circumstances the social standard is likely to predominate. However, there is reason to believe that the standards employed in their study may not have been very salient nor very important to the subjects. In the present experiment, subjects with either conservative or liberal sexual attitudes were exposed to information suggesting a prevailing norm of sexual liberalism. They were then asked to respond to a number of sexual and nonsexual attitude measures while their attention was or was not self-directed by means of a mirror. Primary results indicated that self-awareness enhanced conformity to the social standard (as in Diener & Srull, 1979) for the conservative subjects; however, correlational analyses within the self-focused and non-self-focused conditions indicated that self-aware subjects did not “abandon” their personal standards when responding to the conformity pressure. Instead, their responses tended to be more in line with their previously expressed attitudes than did the responses of the non-self-focused group. Results are discussed in terms of the effects of self-awareness on reactions to potent, but conflicting behavioral standards.     

Effects of response-dependent and independent electric shock on schedule-induced polydipsia

In Experiment I, lever pressing by rats was maintained by the delivery of food pellets under a 45-sec fixed-interval schedule. Fixed-time 180-sec and fixed-interval 180-sec schedules of shock delivery were systematically superimposed on the baseline food schedule to study effects on schedule-induced water intake. Response-dependent shock had little, if any, effect on water intake, whereas shocks independent of lever pressing attenuated fluid intake. In Experiment 2, rats received food pellets under a fixed-time 60-sec schedule. Electric shock delivered concurrently under a variable-time 180-sec schedule, but never while the animal was licking or within 5 sec after licking terminated, led to similar attenuation of water intake. These findings suggest that schedule-induced polydipsia is sensitive to differences in the functional properties of response-independent and dependent electric shock.     

The Stress-Arousal Checklist as a measure of situational stress versus simple arousal

The Stress-Arousal Checklist was developed as a self-report measure both of arousal and of the favorable or unfavorable appraisal of that arousal. Previous studies with the checklist showed differential sensitivity of the two subscales to experimental manipulations. In the present study, the convergent and discriminant validity were further explored by comparing scores with those on the State-Trait Anxiety Inventory-State. The results supported the validity of the two-factor structure.
