Inference of object use from pantomimed actions by aphasics and patients with right hemisphere lesions

Twenty-four aphasic and fifteen right brain-damaged subjects were compared on their ability to identify the objects whose use was depicted in a series of twenty videotaped pantomimes. Aphasics were inferior to right brain-damaged patients in inferring object use. Success was correlated with Performance IQ, but not with language measures. Analysis of movement features contributing to subjects' choices reveal speed of movement and object weight to be the most robust and hand shape and size to be the most fragile.This study was supported in part by the grants from the National Institute of Health (RO1 EY07861) and McDonnell Pew Foundation (T89-01245-017) to LMV and by the USPHS grant NS06209 to H.G. and L.M.V. The authors are indebted to the staff of the Neuropsychology and Communication Disorders Departments at the New England Rehabilitation Hospital for making available the test records of the patients included in this study. All the patients included in the study have signed the informed consent forms according to the regulations of the Human Subjects Committee at New England Rehabilitation Hospital.     

Honest research

The origins of research projects, the duties of supervisors and research workers, the subjective elements in research and the difficulties of publication are reviewed, as a guide to the complexities of executing an honest research project. It is assumed that research carried out with maximal intellectual integrity will result in real advances.     

Gender Differences in Perceptions of How Others Are Affected by Self-Disclosure of Achievement

Three experiments were conducted at two east coast Universities with primarily Caucasian students participating. In experiment one, college students disclosed that they scored in the 91st percentile or in the top half on an intelligence-related test to a female student who had scored either in the 42nd percentile (low-achieving) or the 92nd percentile (high-achieving) on the same test. Women who disclosed modestly (top half) judged that the low-achieving other felt better than women who disclosed immodestly (91st percentile). Also, women who disclosed modestly judged that the other liked them more than women who disclosed immodestly. These effects did not occur with men. In experiment two, college students disclosed that they scored in the 91st percentile or in the top half on an intelligence-related test to either a male or a female student who had scored in the 42nd percentile on the same test. Women who disclosed modestly judged that a female peer liked them more and felt more intelligent and confident than did women who disclosed immodestly. In contrast, men who disclosed immodestly judged that a female peer liked them more than did men who disclosed modestly. Regardless of the peer's gender, women judged that peers felt worse about themselves, were less happy and more upset when subjects had disclosed immodestly. In contrast, men judged that the peer felt better about himself or herself, was happier and less upset when the subjects had disclosed immodestly. In Experiment 3, male and female participants rated the intelligence-related test as equally difficult and rated doing well on them as equally important. Participants also indicated that doing well was equally important to males and females. Thus, ego-involvement is ruled out as an alternative explanation. These findings support the interpretation of previous research that women may choose to disclose modestly in an effort to be better liked or to protect the other's feelings.     

Reliability for the law of comparative judgment

A variance-components analysis is presented for paired comparisons in terms of three components:s, the scale value of the stimuli;d, a deviation from the linear model specified by the law of comparative judgment; andb, a binomial error component. Estimates are given for each of the three variances, _s ² , _d ² , and _b ² . Several coefficients, analogous to reliability coefficients, based on these three variances are indicated. The techniques are illustrated in a replicated comparison of handwriting specimens.This research was jointly supported in part by Princeton University, the Office of Naval Research under contract Nonr-1858(15), and the National Science Foundation under grant NSF G-642, and in part by Educational Testing Service.

Artificial intelligence and metaphor making: Some philosophic considerations

This article argues that the metaphors presently employed in describing artificial intelligence represent the use of personification and anthropomorphism. They attempt to develop an isomorphic relationship between the human mind and a computer’s logic. It is suggested that an analogic metaphor is more appropriate in describing this relationship and is more epistemologically correct. Dr. Carrier is an assistant professor of organizational behavior at the School of Management, Rensselaer Polytechnic Institute, Troy, New York 12180. His current research interests include the behavioral and philosophic aspects of artificial intelligence and expert computer systems in work situations, and the behavioral perceptions of decision processes in the workplace.     

Integration of women into the U.S. military

This study reports male attitudes toward women beginning with the admission of women in 1976 to the U.S. Coast Guard Academy. It assesses these attitudes as a consequence of the norms of the military system and notes a trend toward more positive attitudes by successive classes since the Class of 1979. Programmatic measures to nurture and facilitate this positive trend are recommended.The author gratefully acknowledges the contribution of Dr. Steven P. Gunn, formerly of Connecticut College, to the development of this research.     

Measuring the effects of demand characteristics on the Beck Depression Inventory responses of college students

To determine whether Beck Depression Inventory (BDI) responses could be influenced by an instructional set or by changing the item order, 198 college students were randomly assigned to one of four conditions: instructions designed to facilitate or inhibit responding, along with standard vs. reordered symptom questions. A 2×2 ANCOVA found a main effect only for the inhibitory message. The suppression of scores by the inhibitor instructional set suggests caution regarding possible demand characteristics when using the BDI with this population and should be further studied with clinically symptomatic samples.     

The reliability of a computer interview for drug use/abuse information

A computer interview was developed to collect information about drug use/abuse from high school students. Responses to this interview were compared with those obtained from an identical paper-and-pencil questionnaire given to the same students, in counterbalanced order. Results were comparable for the two methods, but missing data and logically inconsistent answers obtained with the paper-and-pencil questionnaire were not possible with the computer interview. The overwhelming majority of respondents preferred the computer interview as a means of data collection.     

A confirmatory analysis of the factor stability hypothesis

The procedures recently developed by Jöreskog for studying similarities and differences in factor structures between different groups were applied to data from a study designed by Thurstone to investigate the sampling stability of a hypothesized isolated configuration. The hypothesis of an isolated configuration was rejected but not by much. The results represent a restricted and unique simple structure solution with the factor loadings and uniqueness values invariant over the two samples.
