Public information, dissemination, and behavior analysis

Behavior analysts have become increasingly concerned about inaccuracies and misconceptions in the public, educational, and professional information portraying their activities, but have done little to correct these views. The present paper has two purposes in this regard. First, the paper describes some of the conditions that have given rise to these concerns. Second, and more important, the paper surveys various procedures and programs for the dissemination of public information that may correct inaccuracies and misconceptions. Special consideration is also given to issues involving (a) the assessment of the problem, (b) the content and means of dissemination, (c) the possible contributions of behavior analysts to current misunderstandings, and (d) relationships between behavior analysts and the media. The dissemination of accurate and unbiased information constitutes an important new undertaking for behavior analysis. The future of the field may depend in part on such activity.     

Field and laboratory studies of littering

Four studies are reported. In the first, it was shown that littering rates vary substantially across areas of a large urban region and that the rate for a particular area is correlated with the amount of litter already present. It was also found that males litter more than females and young people more than old. In the second study, a laboratory experiment, a causal relationship between the amount of litter in an area and the likelihood it will be littered was demonstrated. A third study replicated this latter finding, but did not find a relationship between the amount of stress experienced by a subject and the likelihood that he or she would litter. In the fourth study, a field experiment, subjects who were approached and asked to sign a petition about clean streets littered less than control subjects.     

The “Three Rs” of Sex

Summary We have seen that sex has three functions, the reproductive, the relational, and the recreational. We have shown it probable that a great deal of unnecessary marital conflict comes from one party holding relational sex to be all-important while the other considers recreational sex to be of more importance. Finally, we have indicated that it is most likely that if they can compromise this difficulty by each meeting the other on his own ground a part of the time, much of the haggling will stop and many unnecessary divorces will be avoided.The Rev. Maxwell H. Morris, Th.D., following studies in the Old Testament and ancient history in the University of Oregon, the University of Washington, and the University of Southern California, spent a year in Jewish studies at the Hebrew Union College for Rabbinical Studies in Cincinnati. His interest in the psychology of sex grew out of his attempts to understand phallic and fertility cults.     

Animal learning of independent and correlated events

Evidence suggests that experience of a truly random presentation of a conditioned and unconditioned stimulus (CS and US) retards subsequent acquisition of a classically conditioned response when the CS and US are paired. In these studies, no events reliably predict the US during the first part of training. The present experiment demonstrated impairment of subsequent appetitive conditioning in rats following a random CS-US presentation, both when another predictive cue is present and when it is absent during this experience. Results are discussed with reference to “general attention” theory, and learned helplessness. However, the data support an interpretation in terms of learning a specific relationship between a particular CS and US.     

Retrieval of pictures and words from long-term memory: Effects upon short-term memory

On each of a series of Brown-Peterson short-term memory (STM) tests, the presentation of a verbal to-be-remembered (TBR) item (a five-letter quintogram in Experiment 1 and an eight-letter octogram in Experiment 2) was followed immediately by a 10-sec retention interval. During the retention interval, subjects recalled and reproduced previously learned paired associate response triads that consisted of three concrete pictures, concrete words, abstract pictures, or abstract words. Following selective retrieval of one of the four types of response triads from long-term memory (LTM), subjects attempted to recall the TBR items from STM. In both experiments, the intervening retrieval of abstract words resulted in significantly poorer retention of the TBR items than did the intervening retrieval of concrete words; the retrieval of concrete words resulted, in turn, in significantly poorer retention of the TBR items than did the retrieval of concrete or abstract pictures. Retrieval of the latter two types of materials appeared not to interfere with the short-term retention of the TBR verbal material (i.e., the quintograms and octograms). The results reflect the occurrence of selective interference effects, and, except for one discrepant finding, appear to be consistent with Paivio’s 11971) dual-coding hypothesis and Shiffrin and Schneider’s (1977) general theory of memory.     

Effects of goodness and other properties of patterns on discriminative performance of monkeys

Subsequent to prism adaptation, subjects may be readaptedto their original visual-motor coordination using procedures similar to those occurring during adaptation. It has been argued that such procedures will be moreeffective than allowing for a decay of the aftereffect if normal visual-motor behavior is itself a state of adaptation. In the present study, two readaptation procedures were compared for their effectiveness to four decay and/or controf conditions. Although all groups, except for one decay condition, showed significant reductions in prism aftereffects, only the two readaptation groups showed final aftereffects that were not significantly different from zero.It is argued that readaptation is distinguishable from decay and, further, that the necessary conditions for readaptation can be elucidated with reference to the information discordance hypothesis of prism adaptation. These arguments are primarily based on an extensive analysis inwhich discrepant informationabout the adapted arm’s position is supplied by a nonvisual search task using the two arms.     

A portable micro-based system for the study of associated movements

This paper describes a microcomputer-based system for the on-line study of associated movements. The system is portable, provides hard copy, includes a backup system, is relatively inexpensive, can be used with simple or choice reaction time paradigms, and is simple to operate.     

Developmental and Adjustment Issues of Gay, Lesbian, and Bisexual Adolescents: A Review of the Empirical Literature

Various studies have reported adjustment problems experienced by gay, lesbian, and bisexual (GLB) adolescents. A primary purpose of this paper is to critically review this literature. Difficulties that have been studied include past suicide attempts, substance use and abuse, conduct problems, and academic concerns. For example, a considerable number of GLB youth report a history of suicide attempts, with prevalence rates ranging from 11 to 42%. However, among other methodological concerns, studies in this area have not used a comparison sample of heterosexual youths. Characteristics of development particular to GLB adolescents are described, the empirical research on adjustment issues is reviewed, and potential risk and protective factors for GLB youths are discussed.
