The communication disorder in dialysis dementia: A case report

The communication disorder in dialysis dementia is an integral feature of the syndrome. This report describes the communication disorder in a 67-year-old man over a period of 4 months from his admission to the hospital to his death. In the early stage of the syndrome, the most prominent feature was a speech problem, the characteristics of which may vary among cases. In the middle stage, it was difficult to distinguish among aphemia, aphasia, or a combination of dysarthria and confusional state. The severity of the problems in these stages was temporally related to the dialysis treatments. The final stage was characterized by constant mutism and was unrelated to the dialysis treatments. Death occurred 10 months after the communication problems emerged. Communication studies of dialysis dementia patients may offer a systematic method to monitor the course of the syndrome, its response to therapeutic trials, and a clinical model for the study of communication disorders in general.     

The use of averaged electroencephalic response techniques in the study of auditory processing related to speech and language

This paper reviews a number of studies done by the authors and others, who have utilized various averaged electroencephalic response (AER) techniques to study speech and language processing. Pertinent studies are described in detail. A relatively new AER technique, auditory brainstem responses (ABR), is described and its usefulness in studying auditory processing activity related to speech and language is outlined. In addition, a series of ABR studies, that have demonstrated significant male—female differences in ABR auditory processing abilities, is presented and the relevance of these data to already established differences in male—female language, hearing, and cognitive abilities is discussed.     

Causal explanations of male and female academic performance as a function of sex-role biases

The study was designed to assess whether attributions of causality vary as a function of sex-role attitudes. Thirty-two male and thirty-two female undergraduates were presented with one of four story completions about a medical student in which sex of the student and success versus failure were varied. Subjects were asked to account for the medical student's success (or failure) in terms of ability, motivation, ease of the goal, and luck. Results suggest that attributions do vary as a function of sex-role attitudes, as measured by the Attitudes Toward Women Scale. Subjects with liberal attitudes were less likely to offer sex-biased attributions about lack of motivation. Subjects' attributions with respect to lack of ability suggest, however, that sex-typed notions about competence may still be deeply ingrained despite recent social changes.The author would like to thank Cheryl Sharp and Robin Koenig for their assistance in compiling the data for this project, as well as Robert Heaton, James Gumina, and Louise Bickman for their editoral comments.     

Decision Control and Process Control Effects on Procedural Fairness Judgments1

Process control, the capacity to influence the content of a conflict resolution hearing, has been found repeatedly to affect disputants' judgments of the fairness of conflict resolution procedures, but never has there been an unambiguous test of the effect in nonbinding procedures. It was hypothesized that disputants experiencing nonbinding conflict resolution procedures, as well as those experiencing binding conflict resolution, would judge as more fair procedures high in disputant process control. One hundred nineteen undergraduate males and females were placed in apparent conflict with other suhjects. The procedure used to resolve the conflict was either high or low in disputant process control and was either binding or nonbinding. The outcome of the conflict resolution procedure was either favorable or unfavordblc to the subject. High disputant process control procedures were judged more fair than low disputant process control procedures regardless of whether the decision was binding, confirming the hypothesis. The results support new applications of procedural fairness theory and research and encourage testing of process control-like variables in nonlegal settings.     

The development of handedness and dichotic ear listening asymmetries in relation to school achievement: A longitudinal study

To assess the development of dichotic ear asymmetries and handedness, 208 male school children were evaluated in kindergarten and at Grades 2 and 5 (ages 66, 92, and 130 months of age, respectively) with a dichotic listening task and a hand preference test. The Wide Range Achievement Test (WRAT) also was administered at each of the three grade levels. There was significant variability in handedness scores over time only for those subjects whose scores at initial testing, that is, in kindergarten, identified them as non-right-handers. Both right and left handers had a significant increase in dichotic listening scores over time; however, only right handers had a significant right ear advantage at each evaluation. Regression analyses showed that combined hand preference scores and ear recall scores at each probe when combined accounted for almost 44% of the variance in WRAT achievement scores at Grade 5. Ear asymmetry scores, however, were not predictive of school achievement.     

Exposure is a necessary condition for fear-reduction: a reply to de Silva and Rachman

de Silva and Rachman (1981) have recently suggested that although non-reinforced exposure of a fear-evoking stimulus constitutes a sufficient condition for unlearning fears, it does not represent a necessary condition. This conclusion was reached, in part, by examples they provide which appeared to them to suggest that fear-reduction can occur in the absence of exposure to the fear stimulus. They then call for an extended search for non-exposure types of intervention, especially those involving ‘sources of information’ and ‘expectations’. After reviewing in detail the arguments advanced, the present authors adopt the position that de Silva and Rachman's conclusions are premature and unwarranted. To abandon or lose sight of one of the most effective and perhaps most important therapeutic principles, CS exposure, would be myopic and detrimental to the advancement of effective behavior change. At this point in time what is needed is a more careful analysis of the extinction process especially at the stimulus level so the effectiveness of this principle can be maximized.     

New assessments of weight-related body image derived from extant instruments

A study of 79 female college students examined the reliability and validity of two new size/weight-related measures of body image. The Body-size Appraisal Scale and the Overweight Preoccupation Scale were derived from existing instruments. Analyses supported the internal consistency and 2-wk. test-retest reliability of both new scales. Correlations of scores on each scale with measures of anxiety about being fat, negative body-image affect and avoidance, restrained and bulimic eating, and depression support their concurrent and construct validity. Scores on the Overweight Preoccupation Scale were also related to the extent of investment in physical appearance. Regression analyses indicated that each new scale could be predicted from several other conceptually relevant body-image attitudes, even after actual body weight was controlled.
