Deriving Training Strategies for Spatial Knowledge Acquisition From Behavioral,Cognitive, and Neural Foundations

While much has been made of the potential uses for virtual environment (VE) technologies as training aids, there are few guidelines and strategies to inform system development from the user’s perspective. Assumptions are that a human factors-based evaluation will ensure optimal performance, transferring training from virtual to real worlds; however, there are complex, yet unexplored, issues surrounding system optimization and employment. A comprehensive investigation into the foundations of training, traversing levels of performance analysis, from overt behavioral responses to the less explicit neuronal patterns, is proposed from which optimal training strategies can be inferred and system development guidelines deduced.     

Adolescent Decisional Autonomy Regarding Participation in an Emergency Department Youth Violence Interview

Much attention has been given to determining whether an adolescent patient has the capacity to consent to research. This study explores the factors that influence adolescents' decisions to participate in a research study about youth violence and to determine positive or negative feelings elicited by being a research subject. The majority of subjects perceived their decision to participate to be free of coercion, and few felt badly about having participated. However, adolescents who were alone in the room during the assent process were more likely to report that they chose freely to be a research subject. This study may influence the ways physicians communicate with adolescent patients around research assent within a clinical care environment.     

Delineating potential mechanisms of implicit alcohol cognitions: drinking restraint, negative affect, and their relationship with approach alcohol associations

Problem drinkers may use alcohol to avoid negative mood states and may develop implicit cognitive associations between negative emotional states and reinforcing properties of drinking. It is paradoxical that attempts to control drinking, such as among those high in drinking restraint, may inadvertently increase desire to drink and subsequent alcohol consumption, and this may be exaggerated under times of emotional distress when urges to drink are high. We examined whether individuals who are high on drinking restraint would demonstrate stronger alcohol-related thoughts elicited by stimuli that represent the desire to use alcohol, in response to stronger versus weaker negative mood arousal. Seventy hazardous drinkers completed measurements of drinking restraint, alcohol consumption, and consequences of use. After being randomized to view negative or positive pictures sets, participants completed an Implicit Association Task (IAT) to test differences in the strength of the association between desire to approach or avoid alcohol or water cues, and then a measurement of subjective craving following the IAT. Regression analyses showed that trait restriction not temptation was positively related to IAT scores, after controlling for relevant covariates and explained 7% of the total variance. Trait temptation not IAT predicted subjective craving. Negative affect was unrelated to IAT scores, singly or in conjunction with measures of drinking restraint, contrary to predictions. In sum, implicit alcohol cognitions are related to attempts to restrict drinking not temptation to drink and are less strongly influenced by mood state.     

Alcohol and group formation: a multimodal investigation of the effects of alcohol on emotion and social bonding

We integrated research on emotion and on small groups to address a fundamental and enduring question facing alcohol researchers: What are the specific mechanisms that underlie the reinforcing effects of drinking? In one of the largest alcohol-administration studies yet conducted, we employed a novel group-formation paradigm to evaluate the socioemotional effects of alcohol. Seven hundred twenty social drinkers (360 male, 360 female) were assembled into groups of 3 unacquainted persons each and given a moderate dose of an alcoholic, placebo, or control beverage, which they consumed over 36 min. These groups' social interactions were video recorded, and the duration and sequence of interaction partners' facial and speech behaviors were systematically coded (e.g., using the Facial Action Coding System). Alcohol consumption enhanced individual- and group-level behaviors associated with positive affect, reduced individual-level behaviors associated with negative affect, and elevated self-reported bonding. Our results indicate that alcohol facilitates bonding during group formation. Assessing nonverbal responses in social contexts offers new directions for evaluating the effects of alcohol.     

Secret ambitions and public performances: The effects of anonymity on reward allocations made by men and women

The degree of equality or equity in reward allocations made by men and women is explored in three studies. Study 1 was a classroom survey which was administered after the members had completed a series of team assignments. When asked to indicate anonymously whether they would share some points with team members who had earned fewer, the men more often said yes and the women no, contradicting the patterns found in much of the literature. Studies 2 and 3 examined the hypothesis that under public conditions men and women would behave as tradition and the previous literature suggest, allocating rewards equitably and equally, respectively. In private, however, they would reverse themselves, each preferring the otherwise forbidden option. The results confirmed the prediction: when anticipating disclosure of their decisions, men chose to divide credits equitably and women equally between themselves and a less deserving partner, but when assured of anonymity, men chose more equal and women more equitable allocations. The results are discussed in light of both childhood socialization and adult constraints on sex role performances.     

Gender differences in distributive justice: The role of self-presentation revisited

Kidder, Bellettirie, and Cohn's [(1977) Secret Ambitions and Public Performances: The Effects of Anonymity on Reward Allocations Made by Men and Women, Journal of Experimental Social Psychology, Vol. 13, pp. 70–80] self-presentational account of gender differences in distributive justice was examined. Men and women attending two, primarily white, northeastern universities distributed a jointly earned reward between themselves and a hypothetical co-worker who was either a stranger or a friend and whose inferior task performance resulted from either low ability or low effort. Subjects made their allocations under both public and private conditions. Men allocated more equitably (i.e., according to co-worker input) in public than women did, whereas women allocated more equitably in private than men did, only when working with strangers who exerted low effort. In addition, among female subjects, private allocations to low-effort strangers were more equitable than public allocations. Among male subjects, however, public allocations to low-effort strangers were more equitable than private allocations. The conditions under which men make equitable allocations and women make equal allocations, and possible reasons for these differences, are discussed.This research was presented at the 62nd annual meeting of the Eastern Psychological Association, April 11–14, 1991, New York, NY. We are grateful to Brenda Major, Victor Benassi, Rebecca Warner, members of the University of New Hampshire Social Psychology Research Group, and two anonymous reviewers for their thoughtful comments on an earlier version of this paper.     

FEMALE AND MALE PERCEPTIONS OF IDEAL BODY SHAPES: Distorted Views Among Caucasian College Students

Recent studies have demonstrated that women overestimate male preferences for thin female figures. This study examined whether women also overestimate the desirability of thin figures among female peers. Using body silhouettes employed by Fallon and Rozin (1985), 87 college women and 118 college men indicated the size of their own body figure, their ideal figure, the figure most attractive to other-sex peers, and the figure most attractive to same-sex peers. As predicted, the female silhouette that women selected as most attractive to same-sex peers was significantly thinner than the silhouette that women actually selected as most desirable. College men also misjudged the body preference of same-sex peers, exaggerating the extent to which other men perceived large physiques as ideal and desirable.     

Prevalence and correlates of postpartum depression in first-time mothers.

The prevalence and correlates of postpartum depression were examined in a large (N = 1,033) sample of married, primiparous, middle-class mothers of full-term, healthy infants; 9.3% met modified Research Diagnostic Criteria for depression. However, 39% of the nondepressed women also reported at least 1 somatic symptom. Depressed women whose symptoms were current obtained elevated scores on the Center for Epidemiological Studies-Depression scale, as did some women who did not meet depression criteria. Depressed women different from nondepressed women on several socioeconomic status indicators and the occurrence of obstetric complications, even in this low-risk sample. These data have implications for the assessment of depression in postpartum women.
