Cardiovascular changes during social competition in a mixed-motive game.

Male and female subjects played a mixed-motive game against a male confederate under either a 20% cooperative or an 80% cooperative strategy while cardiovascular responses were computer monitored. Females had larger heart rate responses than males during play against the competitive strategy, and the opposite was true during play against the cooperative strategy. Subjects who were more competitive during the game or who scored higher on a coronary-prone (Type A) behavior scale or who reported having an action orientation toward life stress tended to have larger heart rate responses during the game than the remaining subjects. The results draw attention to the importance of covert autonomic responses for understanding overt behavioral choices in mixed-motive games and to the potential utility of this behavioral model for studying the role of psychosocial factors in psychosomatic illnesses.     

Alleviation of forgetting of discrimination learning

Reactivation treatments intended to alleviate forgetting in rats were tested in two discrimination tasks—instrumental learning with brightness or with spatial location as the discriminanda. For memories acquired 28 days earlier, forgetting was alleviated with both tasks when testing was preceded by certain reactivation treatments. Therefore, the generality of the effectiveness of reactivation treatments for alleviating forgetting is extended to include discrimination learning and response measures other than go, no-go behavior.     

Test theory without true scores?

This paper traces the course of the consequences of viewing test responses as simply providing dichotomous data concerning ordinal relations. It begins by proposing that the score matrix is best considered to be items-plus-persons by items-plus-persons, and recording the wrongs as well as the rights. This shows how an underlying order is defined, and was used to provide the basis for a tailored testing procedure. It also was used to define a number of measures of test consistency. Test items provide person dominance relations, and the relations provided by one item can be in one of three relations with a second one: redundant, contradictory, or unique. Summary statistics concerning the number of relations of each kind are easy to get and provide useful information about the test, information which is related to but different from the usual statistics. These concepts can be extended to form the basis of a test theory which is based on ordinal statistics and frequency counts and which invokes the concept of true scores only in a limited sense.1979 Psychometric Society presidential address.I want to recognize the contributions which others have made to whatever I have accomplished. First to mention here are my teachers: principally Harold Gulliksen, Ledyard Tucker, and the late Edith Jay. Second, I would like to recognize the importance of my graduate students. Tom Reynolds has been especially important in developing the ideas that I will talk about here today, but at various times, the others have made major contributions in this and other topics. I would like to express also a debt to my family, primarily my wife, Rosemary, who herself has a longterm interest in the psychometric area. Finally, I must acknowledge the financial support of the NIMH some time ago, the Office of Naval Research, until about a year ago, and of the James McKeen Cattell Fund this past year.     

A multimethod analysis of selected self-esteem measures

This study investigated the convergent and discriminant validity of selected measures of global self-esteem and social self-esteem, using the multitrait-multimethod design. Orderliness was included as the third trait for appraising the discriminant validity of the self-esteem measures. Each trait was measured by three different methods: true-false self-report inventory, multipoint self-report inventory, and simple self-ratings. The Tennessee Self-Concept Scale and the Coopersmith Self-Esteem Inventory (short form) were the selected measures of global self-esteem. The revised Janis-Field Feelings of Inadequacy Scale and the Self-esteem scale of the Jackson Personality Inventory were included as measures of social self-esteem, while orderliness measures included the Order scales from the Personality Research Form and Comrey Personality Scales. Results from the multitrait-multimethod matrix and the multimethod factor analysis of data based on 93 males and 103 females provided strong evidence for the convergent and discriminant validity of the various trait measures.     

Excitation and hedonic valence in the effect of erotica on motivated Intermale aggression

The excitatory potential (low, high), the hedonic valence (negative, positive), and the type of content (erotic, non-erotic) of visual stimuli were varied in a factorial design. Male subjects were provoked by a same-sex peer, exposed to communication or, in a no-exposure control, made to wait for a period of time equal to that of communication exposure, and then provided with an opportunity to retaliate against their annoyer. High excitatory potential and negative hedonic valence were found to combine additively in a facilitative effect on retaliatory aggression. No appreciable differences were found in the effect of excitationally and hedonically matched erotica and non-erotica. Exposure to either arousing and displeasing erotica or non-erotica produced levels of aggression significantly above the level associated with the no-exposure control. Exposure to comparatively non-arousing and pleasing erotica or non-erotica failed to reduce aggression, however. The findings were considered to support a model that projects the effect of erotica on retaliatory aggression as a joint function of their excitatory potential and their hedonic valence.     

Motivation×Expectancy×Value: A functional measurement approach

Functional measurement methodology was applied to test theMotive×Expectancy×Value (MEV) model of human motivation. Subjects judged the value of hypothetical games of chance in which hunger, chance of winning a sandwich, and sandwich preference were varied along with similar information concerning a drink. Graphical tests showed excellent agreement between the data and the theoretical properties of parallelism and linear fan shape. Exact statistical tests of goodness of fit confirmed these graphical tests. Despite the complexity of the task, which required integration of six pieces of information, subjects' judgments obeyed a simple cognitive algebra. Applications of functional measurement were suggested for approach-avoidance conflict, level of aspiration, work motivation, and achievement motivation. These methods can provide exact tests of the behavior models in terms of the subjective values at the level of the individual. They thus provide a unified nomothetic-ideographic approach to motivation theory.This work was supported by National Science Foundation grants MBS 74-19124 and BNS 75-21235, and by grants from the National Institute of Mental Health to the Center for Human Information Processing, University of California, San Diego.

Recognition memory in mentally retarded persons

The continuous recognition memory of retarded and normal subjects was assessed. The stimuli were magazine pictures, arranged so that lags of up to 250 pictures occured. The overall performance of the retarded subjects was poorer, in terms of hit rate or d′. However, the differences were present at 0 lag and the slopes of the forgetting curves were similar in both groups. It was concluded that differences between these subjects were due to a perception related process and not to memory.
