Target Groups for Preventing AIDS Among Intravenous Drug Users

The acquired immune deficiency syndrome (AIDS) has rapidly become the most serious medical consequence of injecting illicit drugs. Its potential impact on intravenous (IV) drug use is enormous. Human immunodeficiency virus (HIV, also known as HTLV-III and LAV), the virus that causes AIDS, appears, usually, to lead to lifelong infection. At present there is no effective treatment, and the treatments under development may require lifelong antiviral therapy. Since most of the antibody produced in response to HIV infection does not neutralize the virus, and since there is substantial genetic variation in the virus, it will be difficult to develop a vaccine. Even after vaccines are developed, testing their safety and efficacy will be formidable problems. Until either effective treatment or vaccines are developed, control of the epidemic among IV drug users must be attempted through behavior change/prevention efforts. In this paper we will review the epidemiology of AIDS among IV drug users and characteristics of the IV drug-use subculture relevant to prevention efforts. We will then identify different target groups for these prevention efforts, present available evidence about behavior change in these groups, and then briefly discuss how to prevent transmission of HIV to heterosexual partners who are not themselves IV drug users and to the children of IV drug users.     

Correlates of Children's Usage of Videogames and Computers1

Fourth-, fifth-, and sixth-grade students responded to a questionnaire concerning their experiences with electronic videogames and computers. Teacher ratings of academic achievement, personality characteristics, and behavior patterns were also obtained for each student. These data were used to examine a number of hypotheses concerning potential harmful or beneficial effects of electronic videogames on school-age children, and to provide preliminary evidence concerning the correlates of computer usage by school-age children. Videogame usage showed significant positive correlations with teacher ratings of impulsivity, significant negative correlations with ratings of academic achievement, and little relationship to rated sociability. Videogame use also proved positively related to other social activities and to microcomputer use.     

A NEUROBIOLOGICAL ALTERNATIVE TO THE PERCEPTUAL REINFORCEMENT HYPOTHESIS OF STEREOTYPED BEHAVIOR: A COMMENTARY ON “SELF-STIMULATORY BEHAVIOR AND PERCEPTUAL REINFORCEMENT”

A perceptual reinforcement theory of stereotyped movements is advanced by Lovaas, Newsom, and Hickman (1987) in an effort to integrate a number of diverse observations about the origins and maintenance of this behavior. We, in turn, argue that the theory, as presented, is logically flawed and fails to take into account important biological findings and theory concerning pathological stereotyped acts. An alternative theory, derived primarily from neurological concepts, is briefly described.     

Saying and doing: A contingency-space analysis

Correspondences between verbal responding (saying) and nonverbal responding (doing) may be organized in terms of the classes of verbal/nonverbal relations into which particular instances of verbal/nonverbal response sequences can enter. Contingency spaces, which display relations among events in terms of the probability of one event given or not given another, have been useful in analyses of nonverbal behavior. We derive a taxonomy of verbal/nonverbal behavior relations from a contingency space that takes into account two conditional probabilities: the probability of a nonverbal response given a verbal response and that probability given the absence of the verbal response. For example, positive correspondence may be said to exist as a response class when the probability of doing is high given saying but is otherwise low. Criteria for other generalized classes, including negative correspondence, follow from this analysis.     

The fundamental rule: a study of current usage

Members of the editorial boards of the Journal of the American Psychoanalytic Association, Psychoanalytic Quarterly, and Psychoanalytic Inquiry, plus selected analysts from Canada, France, and England, were asked how they presented the fundamental rule to their analysands and what considerations led to their choice of initial guidelines. Forty-nine of eight-three analysts responded to the survey. The respondents described diversity in phrasing of the fundamental rule, the time in analysis when the guidelines are given, and the reasons for the practice they follow. The method each chose appears to reflect the differing conceptions analysts have of the analytic process. Two major trends emerged: either our respondents emphasized delineating a work or functional framework or contract, or they emphasized establishing an attitude or spirit of cooperation, mutuality and work sharing. In each group respondents differed as to whether they favored minimal or more lengthy instructions. They also differed as to whether they followed a consistent approach or one tailored to the needs of the individual analysand. A source of tension lay in an inclination either to remain in the tradition set by Freud or to experiment with different phrasings and timings. The authors give their reasons for choosing to give explicit instructions, requesting associational material beyond thoughts and feelings, and describing resistance as inevitable and a potential source of insight.
