Tower of Hanoi performance of retarded young adults and nonretarded children as a function of solution length and goal state

Three experiments were conducted with the Tower of Hanoi task to assess problem solving ability in 6-, 7-, 8-, and 10-year-old nonretarded children and mentally retarded young adults of varying maturational ages. In Experiment 1 we gradually reduced the number of moves required for solution until subjects could solve the 3-disk tower-ending problem. Although all groups experienced difficulty with the standard 7-move problem, all but the trainable retarded group readily solved the 6-move problem. The trainable group did not reach a comparable level of success until the 4-move problem. On the 7-move problem the retarded groups performed at the level of nonretarded groups that were maturationally $\text{1}\text{1}\text{2}$ to 3 years younger. An analysis of first moves indicated that subject groups differed in the strategies they used to solve the problems. In Experiment 2, practice effects were ruled out as a source of the superior performance on the 6- than on the 7-move problem. In Experiment 3, 7- and 10-year-old nonretarded children and mentally retarded young adults did not differ on 5-move problems in which configuration of the goal states was varied. A comparison of all 5-move problems judged to have the same depth of search requirements indicated that the tower-ending problems were significantly easier to solve than the partial-tower-ending problems, which in turn were easier than the flat-ending problems. A limited depth of search capacity sets boundaries on the use of sophisticated strategies and, to a large extent, accounts for the retarded groups' maturational lag.     

Gender differences in autonomous and social achievement orientations

This research examined gender differences in orientations toward autonomous and social achievement. Three independent samples of subjects (total N= 359 males and 574 females) completed measures of achievement orientation (including Strumpfer's [1975] Autonomous Achievement Values and Social Achievement Values scales) and relevant cognitive, affective, and behavioral variables. Correlational and factor analyses clearly identified distinct autonomous and social achievement factors for both men and women in each of the samples. Examination of the correlates of achievement orientation indicated that whereas an autonomous achievement orientation is similarly expressed in males and females, there are considerable sex differences in the expression of an orientation toward social achievement. In particular, a social achievement orientation was associated with concerns over social approval and responsiveness to social influence among males, but was generally unrelated to these factors among females. Findings are discussed in terms of several recent hypotheses concerning the effects of sex role norms on the development and expression of achievement needs in men and women.     

Structural models for the mediation of salience effects on attribution

Previous research has demonstrated that salient information is overrepresented in causal attributions. Two experiments were conducted to investigate potential mediators for this effect and to make a case for the use of structural models in explanations of process. Two mediators were considered: enhanced visual recall of salient stimuli and exaggerated schema-relevant recall of salient stimuli. Although analyses of variance supported the visual recall model, structural analyses demonstrated its implausibility. Analyses of variance and structural models revealed that schema-relevant recall, that is, information seen as representative of causal influence, is a plausible mediator; this was particularly true of relevant visual information. Results suggest that salience effects (S. E. Taylor & S. T. Fiske in L. Berkowitz (Ed.), Advances in experimental social psychology (Vol. 11). New York: Academic Press, 1978) are due to: (a) the attentional advantage of inherently salient visual events and (b) the influence of stored visual and nonvisual schema-relevant information on causal judgments.     

The salience of the self in responses to inequity

Previous research has shown that people strive to conform with the standards of significant others in distributive justice. The present research was concerned with the role of attention to the self in the same paradigm. If people are motivated to personally evaluate their own behavior as fair, then self-focus should result in heightened attempts to redress an overpayment inequity. After the subject's criterion of a fair wage was assessed, they were paid either that amount or double it. Orthogonal to this manipulation, subjects were either made objectively self-aware (OSA) or not, by the presence or absence of a mirror. Consistent with the hypothesis, overpaid OSA subjects did more work, but of a poorer quality, than overpaid not-OSA subjects. This was taken as evidence of more zealous attempts to restore a sense of equity, implicating a greater personal need to eliminate the injustice when the discrepancy between pay level and a personal standard of fairness was made more prominent to the self.     

A leaderless approach to a minister's peer-support group

This article describes a support group for ministers that uses a leaderless approach. The group has met for over ten years and as a result of that experience has developed in ways that make it unique. These group characteristics are described and are offered as a general guide for ministers as well as members of other helping professions who are interested in peer support.     

Age and sex differences on the hand test

Investigated age and sex differences on the Hand Test across the life span, while statistically partialing-out the effects of educational level and verbal ability. Subjects were 150 individuals (75 males, 75 females) ranging in age from 20 to 86 years, assigned to one of three age groups on the basis of their chronological age. Participants were administered the Hand Test and the WAIS vocabulary subtest; in addition, years of formal education completed for each subject was obtained. Results indicated that even after statistically adjusting for the effects of education and verbal ability, a number of significant Age. Sex, Age and Sex, as well as Age x Sex interactions were obtained on the Hand Test. It was suggested that, as previous criticisms of projective research with the aged are met, a residue of important personality trends persists.     

Acceleration of the therapeutic process with group

This paper deals with the impact of adding group to individual treatment of patients with neurotic character problems and attempts to illustrate the efficacy of this dual approach. The formidable task for the individual therapist is to make these patients see that their habitual ways of reacting are pathological and stem from repressed intrapsychic conflicts. This task is facilitated in a group in a number of ways since the group setting becomes an arena that affords wider therapeutic scrutiny. Having become aware that behavioral characteristics disguise anxiety, other group members initiate independent efforts to extract the underlying meanings for their fellow members. Their interventions are often more effective and acceptable because they are less likely than the therapist to be perceived in the projected image of the bad parent.Copyright, 1980, Washington Square Institute for Psychotherapy and Mental Health, which published this paper in No. 7 of the Group Psychotherapy Monograph Series, after the paper had been presented at the Seventh Annual Conference of the Group Psychotherapy Department.     

The role of imagery in the representation of linear orderings

Two experiments were carried out to investigate whether visual imagery was used in representing transitive linear ordering relationships. Subjects were presented with passages describing either a linear ordering or a set inclusion relationship, while being subjected to either visual or verbal interference. Performance was tested by asking subjects to judge the truth or falsity of statements concerning both the information presented in the passages and inferences that could be drawn from this information. In neither experiment was there any evidence for the linear ordering material being selectively disrupted by the visual interference task, as would have been predicted by the imagery theory. Thus it is concluded that linear orderings are probably not represented as visual images.
