A multiprocessor system for generating visual displays and controlling experiments

A laboratory is described that is based on an IMSAI 8080 microcomputer and an IMLAC graphics display system. Procedures for using the system are described and illustrated.     

Using the PET microcomputer

This paper describes advantages and disadvantages of the PET microcomputer for use by behavioral scientists. User groups and second-source hardware-software vendors are noted. It is emphasized that the large production volume of the PET is apt to lead to a proliferation of second-source add ons at modest prices.     

A family study of memory processes and their relations to cognitive test scores

Members of 118 families (456 individuals) who had been tested on several measures of cognitive ability were retested on the same battery in order to determine test-retest reliability. They then were administered the Wechsler Adult Intelligence Scale and tests of visual memory, auditory memory, and figure memory, as well as other measures not discussed herein. Intercorrelations of memory tasks were low to moderate. Factor analysis resulted in a four factor solution. The different factors appeared to represent auditory sequential memory (Factor I); visual memory, as measured psychometrically (Factor II); visual memory, as measured experimentally (Factor III); and figure memory (Factor IV). A second order factor analysis yielded two factors, one consisting of basically psychometric measures of memory and the other of measures of memory obtained in the experimental psychological tradition. Memory measures generally showed low to moderate positive correlations with scores on the cognitive test battery. Significant spouse correlations were found for 3 of the 11 measures of memory. Significant midparent-midchild regressions were found for 9 of the 11 memory measures.     

Some cognitive aspects of figurative language: Association and metaphor

This study was designed to explore the relationship between some predictions generated by a cognitive-feature model of association and metaphor understanding. Several kinds of data were collected from University of Tennessee undergraduates on the two key nouns in each of 28 randomly selected metaphors—both in and out of metaphor context—as well as judged goodness and ease of writing interpretations for the metaphors themselves. Interword similarity, free association variability, and characteristics of common property distributions for key-noun pairs were highly intercorrelated (as predicted by the associative model) and also related to metaphor goodness and difficulty of metaphor interpretation (canonical r=0.78). These results provide indirect support for the associative model and also provide some insight into the cognitive processes underlying metaphor understanding.     

The effects of attitudes toward feminism and perceived feminism on physical attractiveness ratings

The effects of perceived feminism of females and attitudes toward feminism of males on physical attractiveness ratings of female stimulus persons (SPs) were investigated, using two alternative hypotheses: first, SPs who are perceived as feminists would be rated as less attractive than SPs not perceived as feminists; second, profeminist males would rate profeminist women as more attractive than nonfeminist women, and vice versa for nonfeminist males. Seventy-six male college students responded to the Smith-Ferree-Miller questionnaire on attitudes toward feminism and then rated on an 8-point scale of attractiveness 6 photographs of female SPs which had been selected from a pretested sample of 18 photographs. Perceived feminism of the SPs in the photographs was manipulated by presenting the raters with four attitude statements, two of which related to feminism. Although there were no main effects for the two variables, significant interaction did occur, confirming the second (attitude similarity) hypothesis. A negative halo effect, as opposed to a belief in the unattractiveness of feminists, was offered as an explanation of the difference in results between this study and the Goldberg, Gottesdiener, and Abramson (1975) study.     

Psychological systems questionnaire: An objective personality test designed for on-line computer presentation,scoring, and interpretation

Previous research efforts to use on-line computer systems for personality assessment are briefly reviewed. Shortcomings in the conversion of paper-and-pencil testing forms to computer media are noted. Construction of a new instrument, specifically designed for use with an on-line computer system, is described. Advantages of this approach are noted.     

Modeling,tuition, and sanction effects on self-control at different ages

The effects of age, modeling, tuition, and sanctions on self-control of motor behavior were examined. Children 6, 7, 9, and 11 years of age individually participated. A male model either: (a) instructed and performed “Simon Says” in the traditional manner, (b) introduced the sanction “Don't” on the inhibition trials, (c) performed an action that differed from the instruction, or (d) gave instructions only. Activation latency and inhibition error were influenced most greatly by the actions of the model and the introduction of a negative sanction, whereas tuition was less effective. Age differences were present for inhibition errors as well as activation latency and error. The discussion focused on the differential effects of modeling and tuition on deviant responding.
