An attitude profile for studies of population psychology

Attitudes toward specific issues in population covary, but are independent enough to warrant separate assessment. Identifiable components include family planning, abortion, contraception, and population management. Modernity may be defined as a norm-setting factor, establishing a baseline around which the four other dimensions may vary. A system of beliefs will be more or less in phase or out of phase depending on the congruence between modernity and the other four indices. Scales to assess each factor were developed, and an attempt was made to minimize unwanted or artifactual variance pertaining to generalized distrust or misanthropy. Five case vignettes were given to illustrate the personological implications of contrasting profile configurations.     

Locus of control,field dependence and the conditions arousing objective vs subjective self-awareness

Observations of persons engaged in quasievaluative situations revealed that the greater amounts of body movement characterized as tension reducing were exhibited by persons holding internal control as opposed to external control expectancies. Conceptualizing situations as varying in the degree to which they allow one to become task involved (subjective self-awareness) or self-conscious (objective self-awareness) it was hypothesized that the latter would be more disruptive to internals, the former to externals. Body movement exhibited during introspection and personal reminiscence supported this hypothesis though no support was found in another task involving the completion of moral dilemma stories. In the latter task field dependent subjects proved to be more affected by self-awareness conditions, writing more normative stories when cues for objective self-awareness were more prominent.     

"Mirror-image" errors without mirror-image stimuli

Recent work has indicated that discrimination between upright and inverted stimuli is difficult when stimuli are one above the other, and discrimination between stimuli turned left and right is difficult when stimuli are side by side. That is, errors are frequent under conditions in which mirror-image confusions can be made. Young children were given a task requiring the matching of orientation of (a) identical realistic figures that could form mirror images of each other or (b) nonidentical realistic figures that could not form mirror images. The same pattern of errors appeared for the identical and nonidentical figures, indicating that the errors are not mirror-image confusions. It is argued that the errors are due to a strategy of matching analogous parts of the two figures.     

High speed memory scanning in mental retardates: evidence for a central processing deficit

Third-grade, high-school, and adult normal subjects and two diagnostic categories of educable mental retardates (cultural familials and encephalopathies) were tested in a Sternberg-type “memory scanning” recognition task. All five groups showed the characteristic linear increase in correct reaction time as the number of items in the memorized set increased. The slopes of the linear functions, however, were steeper for the two retardate samples than for the normal samples, suggesting a central processing deficit which could not be attributed to a lag in development.     

Perception in chess

This paper develops a technique for isolating and studying the perceptual structures that chess players perceive. Three chess players of varying strength — from master to novice — were confronted with two tasks: (1) A perception task, where the player reproduces a chess position in plain view, and (2) de Groot's (1965) short-term recall task, where the player reproduces a chess position after viewing it for 5 sec. The successive glances at the position in the perceptual task and long pauses in the memory task were used to segment the structures in the reconstruction protocol. The size and nature of these structures were then analyzed as a function of chess skill.     

Is dissonance phenomenologically aversive?

This study examined whether dissonance is, phenomenologically, an aversive state. Experimental subjects were induced to write counterattitudinal essays under a high-choice condition. One group of subjects was led to believe that a pill, which they had just taken in the context of a separate experiment, would cause them to feel pleasantly excited. A second group was led to believe that the pill would make them feel tense. A third group was given no information about the pill's potential side effects, while a fourth group expected to have no side effects at all. In this last condition, the results yielded the usual dissonance effect: subjects stated attitudes more congruent with the essay than did subjects in a survey control condition. When subjects were given an opportunity to attribute their arousal to an arousing, but nonaversive pill (i.e., the pleasant excitement condition), this effect was unchanged. In contrast, when subjects could attribute their arousal to an aversive pill (i.e., in the tensè and the no information conditions), this effect was virtually eliminated. These results are consistent with the notion that dissonance is an aversive state and that subjects will seize, when possible, an external attribution for this state.     

An experimental analysis of aversive imagery versus electrical aversive conditioning in the treatment of chronic alcoholics

A series of three experiments is described comparing an aversive imagery and an electrical escape conditioning procedure in the treatment of chronic alcoholics. Treatment effects were objectively measured by recording subjects' alcohol consumption in a semi-naturalistic laboratory setting. In contrast to conventional group outcome studies, the use of single-subject methodology provided a fine-grained analysis of individual response patterns. The aversive imagery and escape conditioning methods did not differ from each other, and were relatively ineffective in suppressing alcohol intake. In contrast, a punishment procedure in which shock was contingent on drinking did effectively suppress drinking. The data suggest that alcoholics can control their drinking by self-administered shock. The implications for the analysis and treatment of alcoholics are discussed.     

Mediators of the effects of magnitude of reinforcement

The characteristics of mediational mechanisms based upon magnitude of reinforcement were investigated using rats. In two experiments, two-choice discriminations were trained in which selections of one lever in one external stimulus and a second lever in another external stimulus were reinforced with food. In the first experiment, it was found that the discrimination was acquired more rapidly when one choice was reinforced with a large number of food pellets and the other with a smaller number of pellets than when other configurations of reinforcement magnitude were provided. In the second experiment, reversal of a two-choice discrimination was found to be facilitated by prior exposure of the animals to the reversed relationships between the external stimuli and magnitudes of reinforcement. These results were consistent with predictions from a stimulus or associative view of anticipatory processes based upon magnitude of reinforcement.     

Resistance to punishment as a function of intensity and frequency of prior punishment experience

Rats with a history of intermittent punishment have been found to persist in the face of continuous punishment. It was predicted from an extension of frustration theory to punishment that increasing the intensity or frequency of intermittent punishment would increase persistence to high fear elicited by continuous punishment. Two experiments, employing 310 rats, verified this prediction for both intensity and frequency manipulations but indicated rather narrow boundary conditions for their effects.     

Extraversion and reactions to cognitive inconsistency

Two studies are reported which test the hypothesis that extraverts are more tolerant of cognitive inconsistency than are introverts. The first study tested this prediction in the context of Heider's balance model. While degree of extraversion did not moderate reactions to imbalance, extraverts did show less aversion to interpersonal disagreement than introverts. When coupled with other recently published data this suggests that extraverts find arousing social situations less aversive than introverts. In support of the main hypothesis, the second experiment showed that extraverts changed their attitudes less than introverts as a result of writing an essay which was counter to their own attitude under conditions where they had high perceived freedom of choice.
