REMEDIATION OF MUTUALLY AVERSIVE INTERACTIONS BETWEEN A PROBLEM STUDENT AND FOUR TEACHERS BY TRAINING THE STUDENT IN REINFORCEMENT TECHNIQUES

This study tested the effect of a social reinforcement training procedure for a problem student on the verbal and nonverbal approval and disapproval of four of the student's teachers. A design incorporating aspects of a multiple baseline within an extended reversal design (ABABA) was employed. Data were taken on the four teachers' approval and disapproval of a student regarded as a major discipline problem and the target student's approval and disapproval of the four teachers during baseline 1, experimental condition 1, baseline 2, experimental condition 2, and a postcheck or baseline 3 condition six weeks after experimental condition 2. Results showed that increased student approval and decreased disapproval were attributable to training procedures. The increased student approval increased three of the four teachers' approval and decreased the disapproval of all four teachers. Six weeks after experimental condition 2, both approval and disapproval by three of the four teachers and the student and disapproval by all four teachers and the student remained changed over baseline conditions. Student and teacher approval and disapproval were highly correlated at statistically significant levels.     

The duration and generalization of attraction

Tested in the present study were the propositions that attraction toward others is lasting and that liked and disliked individuals serve as a basis for liking others. On the first day, subjects received interpersonal evaluations (e.g., judging the intelligence of others) which supposedly had originated with an anonymous person. Following a delay of 1 to 3 days, the attraction of some of the subjects toward the anonymous person was assessed while the attraction of other subjects toward a second anonymous person, who presumably had also evaluated the subjects, was also assessed. These latter subjects were never exposed to the alleged evaluation by the second person. Attraction toward the first person tended to endure and to generalize to the second person.     

Some types of conditioned inhibitors carry collateral excitatory associations

Two experiments using summation tests in conditioned suppression with rats examined whether conditioned inhibitors generated by five different conditioning procedures have an associative structure which includes collateral excitatory associations. The existence of collateral conditioned excitation was inferred from an increase in the amount of manifest conditioned inhibition after a conditioned inhibitory stimulus (CS-) extinction treatment. The five CS-s evaluated were differential, explicitly unpaired, conditional, backward, and trace. With abbreviated conditioning (Experiment 1), the differential and explicitly unpaired CS-s exhibited conditioned inhibitory properties; the conditional, backward, and trace CS-s did not. Repeated extinction presentations of the CS- in the absence of the unconditioned stimulus unmasked conditioned inhibition to the conditional, backward, and trace CS-s revealing moderate degrees of conditioned inhibition for all five CS-s. After more extensive conditioning (Experiment 2), the explicitly unpaired and conditional CS-s were strongly inhibitory and the differential and trace CS-s were moderately inhibitory. The backward CS- was not inhibitory. Repeated presentations of the CS- in extinction unmasked conditioned inhibition to trace and backward CS-s. All five CS-s were now nearly equally inhibitory. That the measured inhibitory power of backward, trace, and conditional (after few trials) CS-s can be modulated by a CS- extinction treatment suggests that they have similar associative structures and carry, in addition to inhibitory associations, collateral excitatory associations that mask the expression of conditioned inhibition.     

AN EVALUATION OF THE VALIDITY OF THE PERSONALITY RESEARCH FORM WITH FILIPINO UNIVERSITY STUDENTS

The cross-cultural validity of a North American personality inventory, namely, the Personality Research Form (Jackson 1984) was examined using 394 university students in the Philippines who were able to speak and read English. Scale validities, with self and peer ratings as criteria, were generally significant but modest. Moderate scale and peer rating reliabilities probably contributed to these results. Elevated scores on a PRF scale designed to detect careless responding suggested failure to understand instructions or insufficient motivation may also account for the findings. Interestingly, recalculating validities for subsamples comprising ‘dependable’ and ‘undependable’ subjects yielded no substantial differences in overall validity. Implications for cross-cultural personality assessment are discussed.     

Sexual harassment: Organizational context and diffuse status

Data from a large survey of federal employees is utilized to compare three broad competing perspectives that suggest effects on sexual harassment within organizations. Three different viewpoints stress power differentials, minority status, and diffuse master status characteristics. Results of the study indicate that intraorganizational theories emphasizing either power inequalities or work group compositional heterogeneities are unable to account for the reported sexual harassment without considering diffuse master status characteristics developed and maintained outside the organization.Dair Gillespie at the University of Utah was instrumental in obtaining the data for this study and commenting on the original analysis. Theda Skocpol at the University of Chicago provided support at the Center for the Study of Industrial Societies during the completion of this research. Comments of Joe Conaty, William Wilson, John Comaroff, and many others were supportive and helpful. Finally, we wish to thank the anonymous reviewers for their helpful comments.     

Human Impulsivity and Choice: A Challenge to Traditional Operant Methodology

“Impulsivity” refers to the choice of an immediate, small reinforcer over a delayed, large reinforcer. Traditional operant methods (single-subject designs, free-operant choice procedures) have frequently been used to study impulsivity in nonhuman subjects but, curiously, have not been applied to humans. Data are reported replicating and extending previous results obtained with an alternative paradigm using a group-statistical design and discrete-trials choice procedure. Adults chose between schedules differing in delay and/or amount of reinforcement, the reinforcer being slides of entertainment and sports personalities. Delay was defined as the interval between a choice response and onset of a slide, amount as the duration of viewing time. Some participants exhibited impulsivity even though such behavior reduced total viewing time. All participants exhibited impulsivity when this behavior increased total viewing time and was thus adaptive. Traditional operant methods may be ineffective in producing the maladaptive form of impulsivity.

     

Field dependence and short-term memory

This study examined the relationship between field dependence and short-term memory. It was predicted that relatively field-independent individuals would perform better on short-term memory tests in which a large amount of interference is assumed to be present than would individuals who are more field-dependent. Subjects' appraisals of their own attentional facility, as well as their thoughts and feelings about the experimental tasks, were also elicited, and were looked at in terms of their relationship to field dependence and short-term memory.
