Transfer of approach responding between punishment and frustrative nonreward sustained through continuous reinforcement

A block of continuously reinforced nonpunished trials was interpolated between acquisition of a runway response with either partial reinforcement or intermittent punishment and subsequent tests for resistance of that response to the suppressive effects of either extinction or continuous punishment. As previous investigations have shown, both the partial reinforcement effect (PRE) and the intermittent punishment effect (IPE) were sustained through the block of continuously reinforced nonpunished trials. Furthermore, the increased resistance to extinction following intermittent punishment and the increased resistance to punishment following partial reinforcement were also sustained through the interpolated continuous reinforcement. These results support a hypothesized similarity of punishment and frustrative nonreward and were interpreted in an extension of Amsel's conditioning model theory of the role of nonreinforcement in the PRE.     

Visual psychophysics on the APPLE II: Getting started

Several routines are described for psychophysical procedures on the APPLE II. Method of adjustment and PEST routines are presented within short demonstration programs. Techniques for synchronized presentation of images in tachistoscope and motion displays are given, as well as methods for saving graphics images for later recall.     

Police Perceptions of Alcohol Intoxication

The accuracy of police perceptions of alcohol intoxication was assessed by comparing officers' impressions of intoxication with quantitative Breathalyzer measurements of blood alcohol concentration (BAC). Eighteen police officers predicted the BACs of 36 students who had consumed either a high or low dosage of alcohol. Results indicated that the officers could not discriminate between students who had consumed either the high or low alcohol dosage. More specifically, the officers were reasonably accurate in their predictions of students in the low alcohol condition, but they strongly underestimated the degree of intoxication of students in the high dose condition.     

The role of a guessing strategy in the Bransford-Franks paradigm

Within the framework of the Bransford-Franks paradigm, variations of two memory models and a guessing strategy hypothesis were evaluated using concepts that differed in the number of atomic units each contained (‘concept size’). Results showed that, though the precise patterns of recognition for concept size were not completely consistent with any of the explanations, the changes in the patterns across concept size agreed with the guessing strategy hypothesis. It was argued that the subject's interpretation of the guessing strategy is likely to be a similar but simpler version of the experimenter-theorist's formal model, with the consequence that, while less sensitive to the finer details of the formal model, it will still reflect coarser differences.     

Religion and the theory of masochism

The various aspects of masochistic personality structures provide a useful model for examining familiar elements of ordinary religious life. Overall theories of masochism can be divided into six general categories which trace masochism to 1) a distortion of love, 2) a need for punishment, 3) a payment for future rewards, 4) a strategy of the weak or powerless, 5) a flight from selfhood, or 6) an effort to be an object for others. In each case, religious analogies can be found exhibiting the same dynamics. Thus, certain religious phenomena may provide cultural or collective responses to the psychological needs at the root of masochism.240     

"Recipe for a Jury" Revisited: A Balance Theory Prediction

This study examined the relationship of three variables to verdict confidence in an experimental simulation of the jury deliberation process. The three variables were: sex of juror, verdict (guilty or innocent), and the similarity or dissimilarity between juror and confederate verdicts (congruence or incongruence). The subjects were 35 male and 37 female college students. They deliberated in groups containing a male confederate who role-played an obnoxious anti-White or anti-Black juror. Results indicated that before deliberation, male and guilt verdict jurors were more confident than females and innocent verdict jurors. After deliberation, however, sex differences in verdict confidence were absent while innocent verdicts jurors were more confident than guilt verdict jurors. Most important, as predicted from Heider's Balance Theory, males who deliberated with a confederate whose verdict was congruent with theirs' became less confident in their verdicts. Unexpectedly, females became more confident. The study's major hypothesis, then, that it may be advantageous for the defense to accept a juror who zealously advocates a guilty verdict, was only supported for males.     

Doing two things at once: The role of temporal compatibility

Performance in a periodically repeating keypress response was measured as a function of the relation between the response patterns required of the two hands. Compared to identical left- and right-hand responses, performance was degraded when the temporal periods of the left- and right-hand responses were not harmonically related. By contrast, performance was not degraded compared to the identical task control when the left- and right-hand responses had the same or harmonically related periods. These findings suggest a limitation in parallel generation of multiple time frames that is assumed to be associated with a late stage of central processing in which response commands are generated.     

Pitfalls in Counseling Alcoholic Clients

Counseling alcoholic clients is a difficult problem for even the most seasoned counselor. Clients' abilities to use denial and manipulation demand a parallel counselor ability to identify dynamics properly, to deal with defenses, and to provide empathetic support while remaining emotionally noninvested. The unique dynamics of alcoholism demand that the counselor develop unique and innovative strategies within the counseling relation, literally to save the life of the client.     

A procedure for studying strategy development in humans

An early version of the computer gameStar Trek was modified to conduct behavioral research. By appropriate use of the starship’s weapon and defense systems, the player can kill enemy ships and avoid destruction. The player’s moves, as well as the time and state of the game environment when each move occurs, are recorded. The procedure tracks performance changes over time very well, and allows the dissection of performance into sequences of commands that reflect the subject’s play strategy. Computer games such asStar Trek could be the basis for experiments that bridge the gap between operant and cognitive research.
