The hidden future: A global view from another paradigm

The authors discuss the idea that sexual inequality may be a key to the world problematique. New findings from the social sciences, history, and prehistory are presented indicating a correlation between social violence and male‐dominated culture.     

Development of assertive responses: Clinical, measurement and research considerations

The development of assertive responses in unassertive individuals is surveyed in terms of clinical application, measurement techniques and experimental study. Case reports indicate that assertive training is an effective technique for a large variety of disorders as it enables patients to overcome deficits in inter-personal functioning. Some of the effective elements in assertive training have been identified by using analogue research designs. In most of these investigations the major focus has been on expressing hostile feelings and thoughts. However, more efforts at instigating positive responses (clinically and experimentally) are warranted. In addition, there is a need to assess the effects on ‘clinically’ unassertive subjects of techniques in which the transfer of training is programmed rather than expected.     

Contingent reinforcement of lowered blood-alcohol levels in an outpatient chronic alcoholic

Recently. the proposition that alcohol abuse is an operant behavior and thus functionally related to its consequences has been investigated under experimental conditions. In controlled laboratory settings, in which inpatient chronic alcoholics are allowed access to alcoholic beverages, alcohol consumption has been markedly altered via operant strategies. Monetary rewards (Cohen et al., 1971), the opportunity to participate in an enriched environment (Cohen et al., 1971). and visits to a girlfriend (Bigelow et al., 1973) have been used as reinforcers for decreased drinking.Other investigators (Sulzer, 1965; Miller, 1972: Hunt and Azrin, 1973) have successfully applied similar contingency management techniques to alcoholics in the natural environment. However, failure to control for the influence of extraneous therapeutic variables (e.g., attention-placebo factors, job counseling) together with reliance on self-report measures of drinking behavior seriously limit the conclusiveness of these results. Objective assessment is particularly essential with operant techniques since consequent events must be systematically scheduled upon the occurrence or non-occurrence of drinking. Documentation of drinking in the natural environment is a difficult task since the alcoholic frequently consumes alcohol when he is alone. In lieu of direct observation, blood alcohol concentrations are an obvious means of objective assessment. Such data are most conveniently obtained via breath tests similar to the ones that law enforcement officers utilize to identify intoxicated motorists.The purpose of the present study was to investigate the influence of reinforcement contingencies on lowering blood alcohol concentrations obtained in an alcoholic's natural environment.     

An experimental analysis of generalization in assertive training

Unassertive psychiatric patients matched on age, diagnosis, and self-reported assertiveness were assigned to one of five conditions, with 10 subjects in each group: Test-Retest, Practice-Control, Practice-Control with Generalization Instructions, Modeling and Instructions, Modeling and Instructions with Generalization Instructions. All subjects were videotaped (Pre- and Post-Test) while responding to ten interpersonal situations requiring assertive responses. Following the Pre-test, subjects in the experimental groups received training on five of the ten situations (training scenes). On the remaining five situations subjects received no training (generalization scenes). Results indicated that the Modeling and Instructions groups effected the greatest changes on seven of the eight components for the training scenes but on only five of the eight components for the generalization scenes. No differences were found between either of the two Practice-Control groups and the the Test-Retest group. Although transfer of training effects were obtained on the generalization scenes, these effects were minimal on an independent in vivo test of generalization. Moreover, an instructional set designed to facilitate generalization to different situations was only partially effective.     

On theoretical and realizable ideal conditions in psychophysics: Magnitude and category scales and their relation

By spacing 10 stimuli (white noise) between 40 and 110 dB according to two criteria [equal response ambiguity (ERA) and equal discriminability (ED)], an attempt was made to construct an “ideal” case for magnitude estimation and category rating. The “ideal” case is defined by linear and constant Weber functions (SDs as a function of scale values) for the two scales, respectively. Altogether, three group and two individual magnitude and category rating experiments were run with these two spacings. It was found that the ERA spacing approximated the ideal case well for both Weber functions and the ED spacing only for the Weber function of the category scale. The general psychophysical differential equation that relates scale values and Weber functions for the two scales allowed good prediction of the category scales from the magnitude scales and the Weber functions. The data suggested a distinction between phenotypic (empirical) and genotypic Weber functions, analogous to “real” and “ideal” cases in physics.     

HYSTERESIS IN THE CONTINUUM OF SUBJECTIVE ANGULAR VELOCITY

Hysteresis, i.e. the difference between subjective midpoints of sensory distances when stimuli are presented in ascending and descending order, was studied for subjective velocity by using a modified method of sensory bisection. The hysteresis effect found differed both with regard to its size and the position of the subjective midpoints from an earlier experiment in which the same authors employed an estimation procedure.
