Consistency,self-consciousness,and the predictive validity of typical and maximal personality measures

Most personality measures which ask for subjects' typical performance have often not been effective as predictors of criterion behaviors. Based upon the maximal performance model of ability tests, predictors were constructed which required subjects to report both how dominant they typically are in a particular situation and how dominant they are capable of acting. The efficacy of these typical and maximal self-reports in predicting typical and maximal expressions of dominance in the laboratory was compared. Self-reports of maximal dominance tended to outpredict self-reports of typical dominance for both typical and maximal laboratory expressions of dominance. In addition, maximal self-reports were of equal predictive validity for both those subjects reporting themselves as consistent in expressing dominance and those reporting themselves as inconsistent (situationally variable). Finally, the extent to which subjects were self-reflective (private self-consciousness) and concerned about their appearance to others (public self-consciousness) mediated the validity of both their typical and maximal self-reports, although the predictive superiority of maximal self-reports was maintained.     

Discriminative vocal conditioning in rhesus monkeys: Evidence for volitional control?

Both emotional and volitional systems are invoked in explaining the control of human vocalizations, but vocal behavior of nonhuman primates is often believed to be totally under emotional control. Monkeys' poor performance on conditioning tasks, especially discriminative conditioning of vocalization (DCV), has been cited as evidence against volitional control. In Experiment 1, rhesus monkeys failed a DCV task in which food was given for vocalizations emitted during an arbitrary visual stimulus, but in Experiment 2, monkeys showed clear discriminative performance when an otherwise comparable shock-avoidance DCV procedure was used. This evidence that monkeys possess some degree of volitional control has implications for the relation between animal vocalizations and the origin of human speech.     

Hemispheric differences in processing emotions and faces.

Visual field differences for the recognition of emotional expression were investigated using a tachistoscopic procedure. Cartoon line drawings of five adult male characters, each with five emotional expressions ranging from extremely positive to extremely negative, were used as stimuli. Single stimuli were presented unilaterally for 85 msec. Subjects (N = 20) were asked to compare this target face to a subsequent centrally presented face and to decide whether the emotional expressions of the two faces, or the character represented by the two faces, were the same or different. Significant left visual field (LVF) superiorities for both character and emotional expression recognition were found. Subsequent analyses demonstrated the independence of these effects. The LVF superiority for emotional judgments was related to the degree of affective expression, but that for character recognition was not. The results of this experiment are consistent with experimental and clinical literature which has indicated a right hemispheric superiority for face recognition and for processing emotional stimuli. The asymmetry for emotion recognition is interpreted as being an expression of the right hemisphere's synthetic and integrative characteristics, its holistic nature, and its use of imagic associations.     

The expectancy model in the analysis of occupational preference and occupational choice

The differences between the factors related to occupational preference and occupational choice were explored for upper-division college students from business and psychology classes. The results strongly supported a valance-instrumentality-expectancy model in the context of occupational choice. Occupational preference was primarily a function of occupational valence, the multiplicative relation between the outcome valences and the instrumentalities of the occupations for these outcomes. Occupational choice was primarily a function of the force to choose an occupation, the multiplicative relaitonship between occupational valence and the expectancy of attaining an occupation and the expected costs of attaining an occupation.     

A general framework for the analysis of concept identification tasks

A general framework is presented for concept identification based on hypothesis-testing theory. It is a modification of the duoprocess theory presented by Chumbley (1972). It is shown how Markov models for various complex concept identification tasks may be derived from this framework and how such models may be analyzed by making use of probability generating functions. Two experiments are described. In experiment 1 three tasks were used: two simple tasks, where the subject either only had to select the relevant dimension in order to solve the problem or only had to learn a short list of paired-associates, and a more complex task, where both processes were needed to reach the solution. The results were in general favorable to the theory. Experiment 2 was designed to test the application of the theory to the four-choice concept problem. The predictions of the theory are compared to those of the subproblem learning theory of trabasso and Bower (1964), modified to include a ‘learning-on-errors’ assumption. The fit of the duoprocess theory was reasonably good and superior to that of the subproblem learning theory.     

Effects of question type and experimenter position on bilateral differences in electrodermal activity and conjugate lateral eye movements

28 dextral males participated in a within-subjects experiment which tasted for the effects of question type (verbal versus spatial) and experimenter-position (in front of or behind the subject) on direction of conjugate lateral eye movements (LEMs) and bilateral differences in skin conductance responses (SCRs). Question dependent asymmetries were observed for LEM direction but not for SCR magnitude. Experimenter-position had no significant effect. The results for LEM direction are consistent with the hypothesis linking eye movements to the left or right with activation of the cerebral hemisphere contralateral to the direction of gaze. The results for SCR magnitude, given certain assumptions, can be reconciled with a hemispheric model of contralateral excitatory control of that system.     

Self-consciousness,evaluation of physical characteristics,and physical attractiveness

Results from an investigation of the relationship between habitual awareness of oneself as a social object (Public self-consciousness) and speed of processing information about the overt self are reported. Since high public self-consciousness subjects report themselves to be concerned about their physical appearance, they were expected to have more readily retrievable evaluative judgments concerning their physical characteristics. Consistent with this prediction, high compared to low public consciousness subjects required significantly less time to report their evaluations of eleven of their physical features. In a second study, high public self-consciousness was shown to be positively related to judged physical attractiveness in two geographically diverse samples. The quicker evaluations of the high public self-consciousness group were discussed in terms of information processing model recently described by Markus (1977).     

Developmental trends in free classification: Evidence for a new conceptualization of perceptual development

Two studies are reported to explore the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both, kinder-garteners, second graders, and fifth graders (approximately 5, 8, and 11 years old) are required to classify sets of stimuli that vary in size and brightness. Triads are used in Experiment 1 and tetrads are used in Experiment 2. Also, in Experiment 2, second classifications, judgments of which classification is “best,” and verbal justifications for classifications are obtained. The general finding is that the kinder-garten data systematically implicate integrality of size and brightness while the fifth-grade data systematically implicate separability of size and brightness. The second-grade data are more ambiguous. Issues related to refining the developmental hypothesis and to extending its supportive data base are considered in a final discussion.     

A process model for Missionaries-Cannibals and other river-crossing problems

We extend a model originally developed by Atwood and Polson (1976) for the water jug task to four isomorphs of the Missionaries-Cannibals problem. Our results show that variation in cover story produced no differences in number of legal moves to solution, but caused large differences in illegal moves. A three-stage process model incorporating means-ends heuristics, assumptions about the utilization of memory, and an illegal move-detection process is able to account for both legal and illegal move data from all four versions of the problem.     

Dissonance and self-perception: An integrative view of each theory's proper domain of application

The literature concerning the controversy between dissonance and selfperception theories is reviewed. It is proposed that the two theories be regarded not as “competing” formulations but as complementary ones and, furthermore, that each theory is applicable only to its own specialized domain. Self-perception theory, it is suggested, accurately characterizes attitude change phenomena in the context of attitude-congruent behavior and dissonance theory attitude change in the context of attitude-discrepant behavior. Attitude-congruent is defined as any position within an individual's latitude of acceptance; attitude-discrepant as any position in the latitude of rejection. An experimental test of these notions produced confirming evidence. Subjects who were given an opportunity to misattribute any potential dissonance arousal to an external stimulus did not change their attitudes, relative to low choice subjects, if they were committed to endorsing a position in their latitude of rejection. If the commitment concerned a position in the latitude of acceptance, however, these subjects did exhibit attitude change relative to low choice subjects.
