STRUCTURAL HIERARCHY AND SOCIAL GOOD IN TZINTZUNTZAN

Social ritual in a Mexican village is described as structural hierarchy with a common semantic base. Stretches of rule-governed behavior are generated through a series of metaphoric transformations of physiological process. The concordant structure that is so-derived constitutes a semantic network that provides and reinforces cultural equilibrium and shared ideology.     

Visual discrimination, categorical identification, and categorical rating in brief displays of curved lines: implications for discrete encoding processes

Visual discrimination, categorical identification, and categorical rating measurements were made on sets of curved-line stimuli drawn from a theoretically uniform continuum with curvature parameter s. In Experiment 1, discriminability of pairs of curved lines separated by a constant distance on the s scale was measured at successive points along the scale. Curved lines were presented four at a time in a 100-msec display, which was followed by a random-dot mask. Discrimination performance was found to vary nonsmoothly with s. In Experiment 2, a categorical identification task was performed in which subjects labeled the curved-line stimuli of Experiment 1 straight, just curved, and more than just curved. From these data, a theoretical discrimination performance was computed that was closely congruent to the discrimination performance of Experiment 1. In Experiment 3, three different categorical rating scales with two, three, and four intervals were tested and each was shown to be less effective than the categorical identification scale for predicting discrimination performance. Mean ratings were, however, highly linear with s, suggesting that the curved-line continuum was psychometrically uniform. Experiment 4 provided further evidence for the uniformity of the curved-line continuum by measuring conventional acuity for curvature. Two rather than four curved lines were presented in each display; duration was increased to 2 sec; and the poststimulus mask was omitted. Acuity was found to vary linearly with s. It was concluded that under conditions in which attention is distributed over a number of elements in the field and in which viewing and effective visual processing time are restricted, performance in discriminating curved-line stimuli may be determined by relatively coarse, discrete visual processes.     

PANNENBERGS POLANYIANISM: A RESPONSE TO JOHN V. APCZYNSKI

Abstract. John V. Apczynski, while presenting a helpful analysis of Wolfhart Pannenberg and Michael Polanyi, does not succeed in showing that Pannenberg's theology is incoherent. Contrary to Apczynski, I hold that Pannenberg's concern for theoretic assertions is not extrinsic but intrinsic and central to his program. Moreover, this concern does not rest directly upon the cultural dominance of impersonal knowing but is a countering of the theological overreaction against it. Polanyi has pioneered the critique of impersonal knowledge, but in Pannenberg's judgment much theology tends to espouse too cheaply the Polanyian elevation of faith as ground of knowing. Pannenberg, while appreciating the relative justification of Polanyi's work, is attempting to thematize afresh—in interesting contrast to Polanyi and, for instance, Paul Tillich—the public, rational structure of faith.     

Impact of social problem-solving training on aggressive boys: Skill acquisition,behavior change,and generalization

This study examined the impact of social problem-solving training on the behavior of five aggressive boys. Acquisition of problem-solving skills and changes in classroom behavior were evaluated using multiple-baseline designs within and across subjects. A generalization-programming procedure to promote the use of problem-solving skills in the natural environment was introduced across children in multiple-baseline fashion. Direct observation and behavior ratings were used to evaluate the treatment. Results indicated that each subject acquired the problem-solving skills at levels comparable to well-adjusted peers. Only one child showed behavioral improvement coincident with problem-solving skill acquisition. Three others showed moderate behavior change after the generalization-programming procedure was introduced. Only one child's gains on teacher ratings were maintained at the 6-month followup. The results suggest that cognitive-behavioral treatment of childrens' aggressive behavior may produce changes of limited magnitude and durability.This paper was based on a doctoral dissertation by the first author in partial fulfillment of the requirements of West Virginia University. The authors wish to thank Lianne Willis for her participation as a therapist. Appreciation is also extended to Barry Edelstein, David Hansen, Daniel Hursh, and Mark Cummings for their constructive comments.     

Humor and Counseling: Close Encounters of Another Kind

The basic premise of this article is that humor has a place in counseling. The paper touches on some of the more prominent theoretical explanations of humor, presents assumptions that seem pertinent to any rationale for using humor in counseling, points out the reasons counselors may have overlooked its value, and considers the uses and abuses of humor. Finally, the implications of using humor, both in terms of training and research, are considered, and a five-point scale for assessing its effectiveness in counseling is presented.     

Choosing to be a managerial woman: An examination of individual variables and career choice

This study examined individual difference variables of female MBA students measured toward the end of their academic careers. Data from these subjects as well as from male MBAs and from male and female MA candidates in elementary education were ordered in a 2×2 female/male, traditional role/nontraditional role matrix of analysis (N=151). Female MBA candidates were found to differ significantly from the other subjects on several dimensions. Female managers-to-be saw themselves as more self-assured, more creative, and higher in initiative than did the others. There was no evidence of fear of identity or of sex-role inappropriateness, which had been suggested in earlier literature dealing with women entering nontraditional careers.     

Changeover delay and concurrent-schedule performance in domestic hens

Six domestic hens were exposed to a series of five pairs of two-key concurrent variable-interval schedules with a range of changeover delays from no delay to 15 s. Times spent responding on each alternative and total, within_, and post-changeover-delay response ratios were analyzed in terms of the generalized matching law. The sensitivity parameters, a, for response and time data were generally low when no changeover delay was programmed but were not 0.0. They were higher for all other changeover-delay values, with some tendency to increase as the changeover delay lengthened at very short delays. Within-delay responding was insensitive to reinforcement-rate differences at all changeover delays (a values close to 0.0). As a result of this insensitivity, post-changeover-delay responding was more sensitive to reinforcement-rate changes than was total responding. Interchangeover intervals increased systematically with changeover-delay duration. Responding, particularly after the changeover delay, was well predicted by an equation based on a reinforcer-loss model.
