An exploration of the Pulfrich effect

Abstract.— The existence of a Pulfrich effect based on ocular convergence was demonstrated by having subjects with a neutral density filter over one eye observe a moving rod in a homogeneous environment. This effect was found to have a smailer magnitude than a Pulfrich effect that was obtained when the rod moved optically in the plane of a dot pattern and thus formed the central equivalents of retinal disparities with the dots of the pattern. Under the latter condition, the latency of subjects' reporting the depth effect was shorter when one end of the rod was visible than when both ends of the rod were concealed. This latency difference occurred because the visible end of the rod formed the equivalent of transverse disparities with the dots surrounding it. The presence of real transverse disparities is known to shorten latencies.     

SCIENCE AND SEMANTICS: THE CASE OF VAGUENESS AND SUPERVALUATION*

Abstract: It is widely assumed that the methods and results of science have no place among the data to which our semantics of vague predicates must answer. This despite the fact that it is well known that such prototypical vague predicates as ‘is bald’ play a central role in scientific research (e.g. the research that established Rogaine as a treatment for baldness). I argue here that the assumption is false and costly: in particular, I argue one cannot accept either supervaluationist semantics, or the criticism of that semantics offered by Fodor and Lepore, without having to abandon accepted, and unexceptionable, scientific methodology.     

EVALUATION OF BUSINESS MEMOS: EFFECTS OF WRITER SEX AND ORGANIZATIONAL POSITION, MEMO QUALITY, AND RATER SEX

This study investigated main and interaction effects of memo quality, attributed author sex and organizational position, and rater sex on evaluation of business memos. Alternative questionnaire versions of four memos to be rated anonymously were mailed to about 500 members of a professional personnel association; 48% were returned. A 2×2×2×2 analysis of variance yielded a large main effect for memo quality; an interaction effect of attributed author sex and position and rater sex for two memos; and other interaction effects for single memos. The results are discussed.     

Institutional Affiliations of Contributors to the Personnel and Guidance Journal: Volumes 47–62

The institutional affiliations of contributors to the Personnel and Guidance Journal were examined for a 16-volume period (Vols. 47–62). Authors from colleges and universities represented the major source of contributions (80%). Colleges and universities were then ranked according to the number of articles submitted in each of the two 8-volume periods studied. The top 25 institutions for the entire 16-volume period were identified and ranked according to their contributions to the Journal. Results were compared to a previous study of Journal contributors to highlight trends across a 32-volume period.     

Diagnostic Model for Assessing the Effect of Developmental Issues on Career Action

The authors describe a Diagnostic Model for Assessing the Effect of Developmental Issues on Career Action that is designed to help career counselors diagnose problems that are interfering with clients' career development and to determine appropriate interventions.     

THE IMPACT OF PERFORMANCE APPRAISAL METHODS ON AGE DISCRIMINATION IN EMPLOYMENT ACT CASES

This study investigated the impact of personal and organizational factors and performance appraisal methods on 53 Age Discrimination in Employment Act (ADEA) federal court cases. Discriminant analysis suggested that the employer was most likely to be the successful party when the employee was younger, particularly between 40-49 years old. Appraisal system characteristics which in previous studies were found to be significantly related to case outcome, were not reported in these case decisions. Traditional legal case analysis was used to explore the relationship of performance appraisal methods and the personnel action giving rise to the complaint.     

Intergenerational Relations and Family Therapy Research'' What We Can Learn from Other Disciplines

Although there are a number of theories regarding intergenerational relations within the family therapy field, few of these theories have been empirically examined. Indeed, intergenerational family research is in its infancy in the family therapy world. This article explores the literature on intergenerational relations within the sociological and psychosociological disciplines in order to understand what is known, and how this information could assist family therapy researchers interested in developing systematic studies of intergenerational relations for the family therapy field.
