Processing the information contained in another's behavior

This study investigates attributions based on behavior congruent with situational demands (in-role) and those based on behavior incongruent with situational demands (out-of-role). By analyzing these processes in terms of a Bayesian inference model, it was possible to determine (a) the diagnostic values observers intially assign to behaviors, (b) the actual informational impact of these behaviors, and (c) the degree of optimality in processing information contained therein. The main results can be summarized as follows: (1) The diagnostic value and actual informational impact of out-of-role behaviors were much higher than those of inrole behaviors. (2) Information about out-of-role behaviors was less optimally processed than information about in-role behaviors. (3) Observers assigned smaller diagnostic values to behaviors which were described in great detail than to behaviors which were described in summary statements. (4) Observers' attitudes influenced their initial beliefs about the actors but not the processing of new information about the actor. (5) The Bayesian inference model predicted observers' inferences reasonably well.     

What a person thinks upon learning he has chosen differently from others: Nice evidence for the persuasive-arguments explanation of choice shifts

Small shifts in choice occur even without discussion, when individuals merely know each other's preference. This appears to support an interpersonal comparison explanation of group induced shifts in choice and to refute explanations based on persuasive argumentation. The present study demonstrates the contrary, that such effects are consistent with the persuasive-arguments formulation and are obtained under particular conditions specified only by the latter theory, to wit: Knowledge of other's choices is assumed to lead a person to think of reasons (arguments) others might have had for their choices-reasons which ordinarily would not come to mind without this knowledge. Such reasoning functions in the same way as persuasive argumentation during group discussion; it causes the person to persuade himself that an alternative course of action now has greater merit than the one he initially preferred. To test this analysis, an experiment was performed in which subjects responded to choice-dilemma items under three different conditions: Following their own choice (I) they learned what several others had chosen and then wrote arguments in support of alternatives given in that same item; (II) they learned what several others had chosen and then wrote arguments in support of alternatives given in a different item; and (III) they received no information about others' choices but merely wrote arguments on that item. As predicted, shifts in choice occurred only if the person knew what others chose and had an opportunity to think about the latter (condition I); they did not occur if an opportunity to think of others' choices was denied (condition II), nor if knowledge of others' choices was withheld (condition III). Content analysis of the arguments subjects produced in conditions I and II completely supported the hypothesis, as did analyses of responses to postexperimental questionnaire which directly asked the subjects about their feelings and thoughts upon learning what others had chosen.     

Perceptual set induction in young children

Perceptual set induction was studied among Indian children from Mysore, ages 4 and 5 years. The method of perceptual-set induction involved a procedure of contrastive classification that had been attempted only once before with an American sample of subjects. Findings of the present study were positive, demonstrating the formation of perceptual sets in preschool age children. Taken together with data from the American sample, the results provide a firmer basis for conceptualization, and for explaining the failure of other studies to find evidence for susceptibility to perceptual sets among young children. The findings are also considered in connection with contemporary ideas about symbolic mediation and production deficiencies in children's memory and thinking.     

An analysis of children's oppositional behavior

The purpose of the present study was to examine the relationship between children's oppositional behavior and the following two variables: number of commands issued and time from command presentation. Twenty-four five year-old children and their mothers served as subjects. The results indicated an increase in oppositional behavior as the number of commands increased. Furthermore, most oppositional behavior occurred immediately following the presentation of a command.This study was part of a larger investigation examining the effects of time-out on noncompliance (Scarboro & Forehand, 1975).The investigation was supported by a grant from the University of Georgia research council.     

The Papago Psychology Service: A community mental health program on an American Indian reservation

A community psychology service run by the Papago Indian tribe and staffed largely by Papago Indians who have been trained as mental health workers is described. This service is unique among mental health services for Indians in that the tribe has complete control of the funds for the service and sets its own policies. It was developed for a rather traditional Indian group, and the culture, the traditions, and the wishes of the Papago community were respected. Consultation with medicine men was built into the program from the start, and adaptation of mental health techniques to fit the culture is stressed. Before this clinic was established, few mental health resources were directly available to the reservation. Similar to other Indian tribes, the Papagos are economically disadvantaged, with an unemployment rate of over 50%, low educational attainment, and very high rates of alcoholism, suicide, and vehicular accidents. The topics covered are the tribe's view of health programs for its people, the present Papago community and traditional means of treatment, traditional psychotherapy adapted to Papago culture, the indigenous Papago mental health worker, and the non-Indian professional consultant.     

On mediation

The mediation-nonmediation dichotomy proposed by the Kendlers (Psychological Review, 1962, 69, 1–16) and subscribed to by Cole and Medin (Journal of Experimental Child Psychology, 1973, 15, 352–355) is reviewed and critiqued. It is proposed that the appropriate question for research is how children mediate, not when they mediate.     

Testing two classes of theories about group induced shifts in individual choice

One class of theories explains group induced shifts in individual choice in terms of interpersonal comparison process. By comparing himself with others a member finds out that his position is uncomfortably discrepant, e.g., he is overly cautious or overly risky. Knowledge of this discrepancy presumably is necessary and sufficient to induce him to change his initial choice. Another class of theories holds that merely knowing one is different from others is unimportant. Shifts in choice occur because during discussion a member is exposed to persuasive arguments which prior to discussion were not available to him. Two experiments were conducted, the results of which give considerable support to persuasive-argument theories and none to those based on interpersonal comparison: When a member did not know whether others were arguing for their own position or were forced to support a position contrary to the one they had originally chosen, and the former in fact was the case, typical shifts in choice were obtained. However, if a member had to argue for a position contrary to the one he had initially chosen (and thus he would not be able to muster highly persuasive arguments) typical shifts did not occur, even though another's initial choice could be accurately inferred.     

Semantic memory verification of binary statements by children at three academic levels

Ninety-six binary statements were administered to 120 children randomly selected from three academic levels. The children were to respond TRUE or FALSE to each statement. Error count and latency for correct responses were used as measures of performance. The Constituent Comparison Model (Carpenter, P., & Just, M. A., Psychological Review, 1975, 82, 45–73), which postulates that verification latency will increase linearly with a linear increase in the number of hypothesized constituent comparisons, accounts quite well for the results obtained in this study. Furthermore, the results suggest an increasing efficiency in semantic memory verification across the three academic levels as reflected by a decrease in variability of performance, a decrease in the time required to read and encode sentences, and a decrease in the time required per constituent comparison.
