MMPI experimental scale correlates of the MAACL--R with male alcoholics.

Concurrent and discriminative validity of the MAACL--R scales were studied by means of correlations with selected MMPI experimental scales (AR, DR, HOS, Poor Morale, and ES) for a sample of 88 male VA alcoholics. Concurrent validity of Anxiety, Depression, Hostility and PASS, and discriminative validity of the Anxiety scale were confirmed.     

An automated version of the digit symbol substitution test (DSST)

An automated version of the Digit Symbol Substitution Test is described that employs a relatively inexpensive, commercially available microcomputer to present and score the task. Advantages of the automated DSST include: (1) objective scoring of both speed and accuracy of test performance, (2) printed copies of test scores, (3) convenient administration under standardized test conditions, and (4) the capacity for repeated assessment of an individual’s performance over time. Task performance data for individual subjects following doses of pentobarbital are presented; these data illustrate both the stability of task performance under constant conditions and the within-subjects sensitivity of task performance to experimental manipulations.     

Inherited predisposition to alcoholism: characteristics of sons of male alcoholics

Sons of male alcoholics (SOMAs) are at markedly heightened genetic risk for the development of alcohol abuse. Study of SOMAs could therefore conceivably increase the efficiency of research aimed at uncovering those heritable factors that predispose to alcoholism. SOMAs manifest observable behavioral, cognitive, and psychophysiological abnormalities while sober and react idiosyncratically to alcohol intoxication. They are most commonly described as conduct disordered and hyperactive, appear heir to a variety of deficits in verbal and abstract cognition, and perform more poorly in the academic environment. SOMAs are characterized by abnormal patterns of cued psychophysiological response, and appear more sensitive to the putatively reinforcing aspects of alcohol intoxication. Various methodological weaknesses permeate the relevant literature. Some straightforward improvements are suggested.     

Some effects of reduction in reinforcement magnitude in a monetary economy with hospitalized alcoholics

A 25% reduction in reinforcement magnitude (RIRM) of money paid to residents of an alcoholic rehabilitation program emphasizing the learning of behavior theory and its applications, was instituted to determine the effects on response rates on six classes of behavior—class attendance, desensitizing sessions, completion of desensitization hierarchies, tests on written material, and ward therapeutic and non-therapeutic activities. The effects of the RIRM condition on the behavior of eight subjects were compared with the behavior of ten subjects who spent a comparable amount of time in the program but were not subjected to the experimental condition (RIRM). The RIRM resulted in a reduction in rate of response on two classes of behavior and an increase in the response rate of a third. The three remaining classes of behavior were not significantly affected, although two of these three showed trends toward a decrease in response rate. Results are discussed in terms of altered response costs, accessory 'or intrinsic rewards. response switching, and individual differences.
