Diffuse Lewy Body Disease: Clinical,Pathological, and Neuropsychological Review

The pathophysiological etiologies and clinical presentations of neurodegenerative dementias have been found to be complex and heterogeneous. Recently, Lewy body inclusions have been identified as an etiological factor in 20–34% of autopsied dementia cases. The term diffuse Lewy body disease (DLBD) is generally accepted as the diagnostic term representative of this currently under-reported and under-recognized disease. This article reviews the literature on the clinical, pathological, and neuropsychological features of this disorder. Differential diagnostic issues are discussed as well as current pharmacological treatment. Nine confirmed cases of DLBD are presented to demonstrate the various features of this disorder. The diagnostic implications of neuropsychological examination results are discussed in relation to other common dementing neurologic diseases.     

The Beck Anxiety Inventory: Psychometric Properties with Older Adults

The assessment of anxiety disorders in late life is often hindered by the lack of measures specifically validated with older adults. Because anxiety manifestations may vary across age groups, it is important to design new instruments or validate existing measures with older adults. This study examined the psychometric properties of the Beck Anxiety Inventory (BAI) in a sample of 281 older adults who were community-dwelling (82.6%) or living in residential care facilities (17.4%). The mean total BAI score was 6.5 (SD = 7.2), indicating minimal anxiety symptomatology in this older sample. There was a trend for older subjects to score higher. Females scored higher than males, and subjects living in a residential facility scored higher than did community dwellers. Item-total correlations were in the moderate range and the internal consistency of the BAI was adequate (alpha = 0.89). A factor analysis yielded a six-factor structure accounting for 64.6% of the variance, with a somatic factor accounting for the largest portion of the variance (32.2%). Because somatic symptoms are more prevalent with aging, such symptoms should not be weighed as heavily in the total BAI score as cognitive or behavioral symptoms. The findings indicate that the BAI is a useful self-report scale for assessing anxiety symptomatology among older adults.     

Effects of Environmental Odor and Coping Style on Negative Affect,Anger, Arousal,and Escape1

Trait coping, state anger, perceived arousal, blood pressure, negative affect, and escape behavior were measured in a sample of 240 undergraduate males and females exposed to 1 of 4 foul-odor conditions or to a no-odor condition. Consistent with Baron and Bell's (1976) negative-affect-escape model, it was hypothesized that people exposed to noxious odors would experience increased negative affect and heightened motivation to escape the situation. Results showed that negative affect and motivation to escape, but not anger or arousal, increased significantly as odor became more noxious. In addition, anger and motivation to escape significantly predicted negative affect. Variances in anger and perceived arousal, but not discomfort and escape, were accounted for mainly by trait coping styles and gender differences. Variances in discomfort and escape were accounted for mainly by odor alone.     

Cognitive modeling of consultation processes: A means for improving consultees'' problem definition skills

This study investigated whether consultees' understanding and use of problem definition skills could be enhanced by increasing their awareness of these processes during consultation interactions. Subjects assigned to a consultation with cognitive modeling group viewed videotaped consultation interactions in which consultants' verbalizations during the problem definition stage of consultation frequently included overt references to the problem-solving processes being used by these consultants. Subjects in a consultation without cognitive modeling group viewed similar interactions except that the consultants' statements did not include overt references to problem-solving processes. A control group viewed irrelevant interactions between consultants and consultees. Data analyses indicated that the subjects exposed to consultations that included cognitive modeling components wrote better problem definitions and were better able to describe the process for defining children's problems than subjects in either the consultation without cognitive modeling or control groups. The subjects in the consultation without cognitive modeling group generally did better than those in the control group.     

Sex and achievement domain: Cognitive patterns of success and failure

Subjects (N=439) were asked to write an account of an achievement of failure, and to describe it in terms of locus of standards (internal-external), conceptual focus (process-impact), and initial expectations for success (or failure). Additionally, accounts were classified on the basis of achievement domain (personal, interpersonal, mastery). Analyses of variance [2 (sex)×3 (domain)] for each cognitive measure revealed few sex differences. However, cognitive responses did vary as a function of achievement domain. Main effects for domain were observed under success instructions for locus of control (p<.0002) and under failure instructions for locus of control (p<.05), conceptual focus (p<.05), and expectations (p<.06). Interaction effects of sex and achievement domain were observed on locus of standards for success (p<.0002) and initial expectations preceding failure (p<.025), indicating that women were more responsive to domain differences than were men. Discriminant analyses indicated that cognitions were more readily patterned in terms of achievement domain than sex. Elaboration and incorporation of the concept of domain in cognitive models of achievement is suggested.     

Gender,prejudice, and categorization

In a replication of a study by Taylor and Falcone (Cognitive Bases of Stereotyping: The Relationship Between Categorization and Prejudice, Personality and Social Psychology bulletin, 1982, 8, 426–432), subjects (n=161) listened to videotapes of three males and three females in a staged discussion of ways to increase voter turnout. Subjects subsequently attempted to identify which speaker had made each of the suggestions offered during the discussion. In confirmation of Taylor and Falcone, both sexes made significantly more within-sex than cross-sex attribution errors, suggesting the importance of gender in processing information. Subjects also rated the speakers on items reflecting their likability and their competence. Contrary to Taylor and Falcone, no promale prejudice effects were found. Relationships were also determined between the dependent variables and subjects' scores on a measure of sex role attitudes and on the M (instrumentality) and F (expressiveness) scales of the Bem Sex Role Inventory (BSRI; S. L. Bem, The Measurement of Psychological Androgyny, Journal of Consulting and Clinical Psychology, 1974, 42, 155–162) and the Personal Attributes Questionnaire (PAQ; J. T. Spence, R. Helmreich, and J. Stapp, The Personal Attributes Questionnaire: A Measurement of Sex-Role Stereotypes and Masculinity-Femininity, JAS Catalog of Selected Documents in Psychology, 1974, 4, 143). No Significant BSRI or PAQ effects emerged, thus failing to replicate either the results for within-sex errors reported by Taylor and Falcone or those subsequently reported by Frable and Bem (If You Are Gender Schematic, All Members of the Opposite Sex Look Alike, Journal of Personality and Social Psychology, 1985, 49, 459–468).The authors wish to thank Glenn Cunningham, who served as experimenter along with the first author.     

Children's use of expectations as a source of information in language comprehension

Six studies of children's comprehension of the passive transformation and of the Minimum Distance Principle are reviewed and their results integrated. Children were in kindergarten through Grade 6, inclusive. Expectations about usual grammatical relations (e.g., agent/action combinations) significantly affected children's comprehension: sentences reflecting expectations were understood more often than sentences contradicting children's expressed expectations. Results are discussed within the framework of referential event strategies in understanding spoken language. Limits of the effect of children's expectation on comprehension are described, including general cognitive developmental status, relevant belief systems, and nature of the psycholinguistic task.     

An examination of secondary reinforcement,operant conditioning,and status envy hypotheses in relation to sex-role ideology

A series of predictions concerning adult sex-role ideology was derived from three theoretical approaches commonly applied to the sex-role development of children: secondary reinforcement, operant conditioning by peers, and status envy. Relevant data were collected by means of a questionnaire administered to 635 students at two regional state universities and to nonstudent adults in the surrounding communities. Of these, 226 were classified as having a distinctive contemporary or traditional sex-role ideology by means of a short test developed and validated by the authors for this purpose. Discriminant analyses indicated that each theoretical approach differentiated between contemporary and traditional subjects at levels significantly better than chance. However, the status envy approach, as modified by social learning theory, was most effective and correctly classified 85% of the females and 93% of the males according to their sex-role ideologies. Alternative explanations of results are discussed and an eclectic model is advocated.The authors would like to express their sincere appreciation to Dr. Barbara Wallston for her comments on an earlier draft of this paper, and to Jan Curley for computer assistance.     

Mental rotation and perceptual uprightness

Performance in Cooper and Shepard’s (1973) mental rotation task was examined in the context of a model that defined the extent to which alphabet letters could be tilted from their normal orientation and still be perceptually upright. For letters with a broad range of orientations for which they remain perceptually upright, a nonlinear effect of orientation on reaction time was obtained (as in Cooper and Shepard). However, for letters with a narrow range of orientations for which they remain perceptually upright, reaction time was linearly related to orientation. The results supported the hypothesis that subjects in the Cooper and Shepard task would mentally rotate alphabet letters only when they were presented in orientations for which they were not perceptually upright.     

Evaluation of male and female applicants for sex-congruent and sex-incongruent jobs

The present study was designed to assess whether applicants for a sex-incongruent position would be evaluated less favorably by personnel administrators than applicants for a sex-congruent position. It was predicted that negative evaluations of sex-incongruent applicants would increase as a function of participants' reliance on sex-role stereotypes. Forty-four personnel administrators were asked to review the qualifications and evaluate one of four job applicants. Sex of the applicant and sex-orientation of the position were systematically varied. Participants were presented with credentials of a male or female applicant for a traditionally male- or female-oriented position. While results did not support Cohen and Bunker's contention that sex-incongruent job applicants would be viewed less favorably, the data did suggest that evaluations of the sex-incongruent applicants (especially the female applicant) varied as a function of sex-role stereotyping.The authors wish to gratefully acknowledge the assistance provided by Thom Hurlburt, Joan Van Tassel, and Amy Post.
