Anterior cerebral asymmetry and the nature of emotion.

This article presents an overview of the author's recent electrophysiological studies of anterior cerebral asymmetries related to emotion and affective style. A theoretical account is provided of the role of the two hemispheres in emotional processing. This account assigns a major role in approach- and withdrawal-related behavior to the left and right frontal and anterior temporal regions of two hemispheres, respectively. Individual differences in approach- and withdrawal-related emotional reactivity and temperament are associated with stable differences in baseline measures of activation asymmetry in these anterior regions. Phasic state changes in emotion result in shifts in anterior activation asymmetry which are superimposed upon these stable baseline differences. Future directions for research in this area are discussed.     

On the Relation Between Time Perception and the Timing of Motor Action: Evidence for a Temporal Oscillator Controlling the Timing of Movement

Studies of time estimation have provided evidence that human time perception is determined by an internal clock containing a temporal oscillator and have also provided estimates of the frequency of this oscillator (Treisman, Faulkner, Naish, & Brogan, 1992; Treisman & Brogan, 1992). These estimates were based on the observation that when the intervals to be estimated are accompanied by auditory clicks that recur at certain critical rates, perturbations in time estimation occur. To test the hypothesis that the mechanisms that underlie the perception of time and those that control the timing of motor performance are similar, analogous experiments were performed on motor timing, with the object of seeing whether evidence for a clock would be obtained and if so whether its properties resemble those of the time perception clock. The prediction was made that perturbations in motor timing would be seen at the same or similar critical auditory click rates. The experiments examined choice reaction time and typing. The results support the hypothesis that a temporal oscillator paces motor performance and that this oscillator is similar to the oscillator underlying time perception. They also provide an estimate of the characteristic frequency of the oscillator.     

Dominance,sex, and leader emergence

A 3×2×2 incomplete factorial design was employed to test the effects of sex, dominance, and their interaction on leader emergence. The factors included dominance distribution (high/high, high/low, middle/middle), sex (male-female), and dyad composition (mixed sex-same sex). The subjects were all Caucasians and were pretested on the California Psychological Inventory Dominance Scale. The data revealed that dominance was a predictor of leader emergence in same-sex conditions where high-dominant individuals assumed the role of leader in much greater proportions than their low-dominant partners. In mixed-sex dyads, sex appeared to be a more potent predictor with males becoming leaders at levels greater than would be suspected given dominance levels.     

The use and opposition of rape myths in prime-time television dramas

The act of rape violates two deeply held values of American culture: the right to justice and the right of physical integrity. Despite this fact, thousands of women are raped each year. The victim of rape often becomes the target of blame; in one aspect or another she is held accountable for her victimization. Through the use of rape myths, which are grounded in patriarchal expectations of gender role behavior, our culture unites the apparently dichotomous opposites of the rights to justice and physical integrity. While rape myths have received extensive attention from behaviorists, their communication through the mass media has been ignored. This study focuses on the use of, and opposition to, rape myths in prime-time television dramas, as well as discusses the implications of those depictions.This study was derived from my doctoral dissertation, which was directed by Dr. Pamela Benoit, University of Missouri — Columbia.     

Environmental factors in suicide in long-term care facilities.

One major purpose of this study was to identify environmental factors related to suicide in long-term care facilities. Questionnaires were mailed to a random sample of administrators at 1,080 facilities. Information was collected on facility characteristics, overt suicide, and intentional life-threatening behavior. Chi-square analyses revealed 4 environmental characteristics related to suicidal behavior and deaths from suicide: staff turnover, size, auspices, and per diem cost. More suicides occurred in larger facilities and facilities with higher staff turnover. Religious or "other" facilities experienced more suicidal deaths than public or private facilities; facilities charging less experienced more deaths.     

An intergenerational analysis of expectations for women's career and family roles

This study examined the career and family role expectations and attitudes of women university students and both of their parents. Data collected from 292 families revealed that most daughters and their parents were traditional in their attitudes toward mothering, held somewhat egalitarian attitudes toward marital roles, and generally expected daughters to experience little frustration regarding future career and family roles. Differences and similarities among daughters, mothers, and fathers as well as between intact and dissolved families of various SES were examined. Implications of findings and suggestions for future research were discussed.This research was supported by grants from the University of Rhode Island Council on Research and from the College of Human Science and Services.
