Sexual Communication in Relationships: When Words Speak Louder Than Actions

Sexual communication for expressing sexual desires and gathering HIV risk information were examined as interpersonal constructs related to HIV risk reduction. Community women (n = 816) with at least one heterosexual HIV risk factor (79% Euro-American, 86% some college) completed surveys assessing assertive communication with a sexual partner, HIV risk, and demographic, sexual history, interpersonal negative, and cognitive/attitudinal constructs which formed a hierarchical predictor model. In relationship context comparisons, women with a known partner HIV risk responded more negatively on most measures. Multiple regressions suggested communication is part of an overall cognitive/attitudinal approach to HIV risk, although specific predictors differ by type of communication and partner risk level. Implications for interventions considering relational context, interpersonal power, and counteracting silence are discussed.     

The Economic Benefits of Increased Treatment Duration and Intensity in Residential and Outpatient Substance Abuse Treatment Settings

This study presents estimates of the economic benefits to society from community-based substance abuse treatment. The analysis focused on the impact of length of stay and frequency of counseling on clients' crime-related and health care costs, welfare receipts, and income taxes. The results indicate that the benefits from an additional day of treatment were on average $21 for short-term residential treatment (or 29% the cost of a day of care), $13 for outpatient drug-free treatment (or 94% the cost of a day of care), and $5 for long-term residential treatment (or 9% the cost of a day of care). No benefits were found from additional counseling provided by a client's primary therapist. Withthe exception of short-term residential care, estimated increases in client earnings from longer lengths of stayexceeded the benefits to society. Our estimates do not include benefits realized during treatment or beyond the year after treatment.     

Structural Priming as Implicit Learning: A Comparison of Models of Sentence Production

Structural priming reflects a tendency to generalize recently spoken or heard syntactic structures to different utterances. We propose that it is a form of implicit learning. To explore this hypothesis, we developed and tested a connectionist model of language production that incorporated mechanisms previously used to simulate implicit learning. In the model, the mechanism that learned to produce structured sequences of phrases from messages also exhibited structural priming. The ability of the model to account for structural priming depended on representational assumptions about the nature of messages and the relationship between comprehension and production. Modeling experiments showed that comprehension-based representations were important for the model's generalizations in production and that nonatomic message representations allowed a better fit to existing data on structural priming than traditional thematic-role representations.     

Maternal Acceptance and Consistency of Discipline as Buffers of Divorce Stressors on Children's Psychological Adjustment Problems

This study examines whether two aspects of mothering—acceptance and consistency of discipline—buffer the effect of divorce stressors on adjustment problems in 678 children, ages 8 to 15, whose families had divorced within the past 2 years. Children reported on divorce stressors; both mothers and children reported on mothering and internalizing and externalizing problems. Multiple regressions indicate that for maternal report of mothering, acceptance interacted with divorce stressors in predicting both dimensions of adjustment problems, with the pattern of findings supporting a stress-buffering effect. For child report of mothering, acceptance, consistency of discipline, and divorce stressors interacted in predicting adjustment problems. The relation between divorce stressors and internalizing and externalizing problems is stronger for children who report low acceptance and low consistency of discipline than for children who report either low acceptance and high consistency of discipline or high acceptance and low consistency of discipline. Children reporting high acceptance and high consistency of discipline have the lowest levels of adjustment problems. Implications of these results for understanding variability in children's postdivorce adjustment and interventions for divorced families are discussed.     

Footballs Versus Barbies: Childhood Play Activities as Predictors of Sport Participation by Women

The present study examined the extent to which childhood play activities predict future sport participation by women. Eighty-four college women (40 Division III varsity athletes and 44 nonathletes) at a predominantly White liberal arts school in the Southwest completed a questionnaire that measured their adult experiences with sports as well as their childhood play activities. The results revealed that playing with masculine (rather than feminine) toys and games, playing in predominantly male or mixed-gender groups, and being considered a tomboy distinguished between women who later became college athletes and those who did not. These findings suggest that childhood play activities should be considered, along with other agents of socialization (i.e., family, peers, coaches), as important factors in predicting future sport participation by females.     

BEHAVIORAL GERONTOLOGY: APPLICATION OF BEHAVIORAL METHODS TO THE PROBLEMS OF OLDER ADULTS

Elderly persons are under-represented in research and clinical applied behavior analysis, in spite of data suggesting that behavior problems are quite prevalent in both community dwelling and institutionalized elderly. Preliminary investigations suggest that behavioral procedures can be used effectively in treating various geriatric behavior problems. We discuss a number of areas within behavioral gerontology that would profit from additional research, including basic field study, self-management, community caregiver training, institutional staff training and management, and geriatric behavioral pharmacology. Special considerations for adapting behavioral procedures are discussed, and suggestions for expanding the role of behavior analysis in geriatric care are offered.     

Intracerebral scopolamine administration attenuates Pavlovian heart rate conditioning in the rabbit

Scopolamine hydrobromide was injected into the a) septum, b) dorsal hippocampus, or c) lateral ventricles of conscious rabbits via bilateral chronic indwelling cannulas. The cardiac orienting reflex (OR) and heart rate (HR) classical conditioning were assessed. A fourth group of animals received injections of the vehicle solution into these same brain areas and were otherwise similarly trained. Scopolamine had no effect on the cardiac OR produced by unreinforced tone stimuli. The OR consisted of pronounced bradycardia that habituated over successive trials in all groups. The HR change during classical conditioning also consisted of bradycardia. However, these conditional HR changes were attenuated by scopolamine injected into the septum and lateral ventricles, but were not affected by injections into the dorsal hippocampus. These results suggest that centrally applied scopolamine may affect a central nervous system associative process, and not a mechanism directly involved in primary bradycardia.     

Optimal design of parity tests

Researchers often test a null hypothesis of no ability in the populattion (the so-called “parity” hypothesis) using a single, forced-choice question with k alternatives. In this study a result is presented which should help researchers select the number of alternatives that maximizes the statistical power of the parity hypothesis test. Also the conditions under which it is always beneficial to add alternatives to the test are derived. Finally, the derived result is used to compare several popular parity test designs. The results show that the frequently used triangle test is optimal under a very broad range of plausible conditions.     

Romantic Commitment and the Perceived Availability of Opposite-Sex Persons: On Loving the One You're With1

This article reports a study that examined whether perceptions of the availability of members of the opposite sex are related to commitment to romantic relationships among students at two colleges. Analyses of students' anonymous questionnaire responses reveal that students who perceived that there were relatively few members of the opposite sex on their college's campus were more committed to their romantic relationship, considered their relationship to be more attractive, and invested more in it compared with other students. These relations involving the perceived opposite-sex ratio did not vary as a function of the length of the romantic involvement or the students' gender, race, or college. The perceived opposite-sex ratio was significantly related to the actual opposite-sex ratio, but the latter was not significantly related to commitment, investments, or perceived attractiveness of the relationship. Considering the sample as a whole, the students overestimated the availability of opposite-sex persons. It is concluded that perceptions of the availability of persons of the opposite sex may affect the dynamics of relationships between men and women. Implications of the findings for social exchange theories are discussed.
