Directory of Members of the Society for Personality Assessment as of April 1, 1974

A handwriting analyst blindly rated standard handwriting samples of 22 subjects on five personality dimensions chosen and defined by her in consultation with two counseling psychologists, who rated the same subjects independently on the same scales. Although there was some evidence of inter-counselor agreement, there was no clear evidence of agreement between the analyst's ratings and those made by the counselors.     

CONDITIONING MODELS OF ANXIETY

A critical examination is made of some behavioristic conceptualizations and treatments of chronic anxiety which are mostly based on a classically-conditioned fear model. A new model is proposed wherein it is assumed that tonic emotional states such as anxiety are more based on instrumental conditioning. This model has been successfully tested in experiments with monkeys. Questions remain about the relevance of this model with regard to the natural actual life etiology of these disorders.     

The effect of UCS intensity in classical and avoidance GSR conditioning

This study compared GSR avoidance and yoked-control conditioning procedures. Classical conditioning at two UCS intensities was followed by extinction and, two months later, by an avoidance session. Matching of Ss was based on GSR responsiveness and classical conditioning in the first session. The strong UCS led to more rapid reduction in CR latency (due to an increase in number of Ss responding) in the first session, and there was a tendency for maximum CR magnitude to occur in fewer trials with the strong UCS. No UCS-intensity difference in level of responding to the CS or UCS was found in the first session. A greater amount of spontaneous recovery in the second session was found in the strong UCS group. The avoidance and yoked control groups did not differ in CR magnitudes, latencies, or frequencies, nor in UCR magnitudes in the second session. They did differ significantly in the rate of decline in intertriai responses, the decline being more rapid in the avoidance condition.     

Blocking and unconditioned response diminution in human classical autonomic conditioning

Four experiments examined blocking and UR diminution in human SCR conditioning. In Experiment 1, CS_X was conditioned in compound with previously conditioned CS_A, in one group, or in a compound with another novel stimulus, CS_N, in an additional group. UR diminution occurred, but there was no post-compound difference in CRs in the two groups and no difference in responding to CS_X and CS_A following equal training on each, i.e., no blocking. The correlation between blocking and UR diminution was not significant. In Experiment 2, two groups received a blocking procedure, but one was tested on CS_X and one on CS_A. UR diminution occurred, but there were no post-compound CR or UR differences. There was again no within-subjects blocking effect. The correlation between blocking and UR diminution was not significant, but this correlation was significant when data from Experiments 1 and 2 were combined. In Experiment 3, a differential conditioning procedure was used, followed by reinforcement of two compounds, one with CS_A+ and one with CS_A-. One subgroup was tested on CS_A+ and CS_A- with reinforcement; another was tested without reinforcement. UR diminution occurred, and there was significant blocking, but only after two nonreinforced tests. Blocking and UR diminution were significantly correlated. In Experiment 4, four groups received compound conditioning after initial training with CS_A. The compound contained CS_X and CS_A for three groups and two novel CSs for the fourth. Ten nonreinforced test trials were run. The three blocking groups received two CS_As plus eight CS_Xs, four CS_As plus six CS_Xs, or all CS_Xs. The fourth group received ten nonblocked CS_Xs. CR magnitude to blocked CS_X was significantly smaller than to nonblocked CS_X during the last six test trials, but not initially. Blocking and UR diminution were not correlated, in disagreement with the first three studies. The results indicated that repeated nonreinforced test trials are needed for blocking to be observed in this preparation. The proposition that blocking and UR diminution are both due to reduced processing of the US received only partial support.     

Contextual conditioning

Eastern and Western interpretations of contextual control of phasic conditional responses (transswitching) are contrasted. The Eastern (Asratyan, 1965) approach emphasizes the role of the tonic conditional stimulus and the (hypothetical) tonic response it evokes. The Western (Lachnit, 1986) approach emphasizes the role of compound conditional stimuli. Although Lachnit showed that transswitching-like results can be obtained without a tonic stimulus, attempts to simulate transswitching experiments using a computer model of the Rescorla-Wagner theory (Kimmel and Lachnit, 1988) have shown that predictions from the theory approximate empirical results in human classical conditioning only when the tonic stimulus is given far greater weight than the phasic stimulus. In other words, only when the Rescorla-Wagner theory is made more like Asratyan’s theory, can the compound conditional stimulus approach account for real empirical transswitching data.     

The interactive effects of request form and speaker status on judgments of requests

The interactive effects of request form and speaker status on judgments of requests were investigated in a laboratory study of metapragmatics. College students (N=132) read scenarios in which speakers made requests of them. Speakers were higher in status, peers, or lower in status than the subjects, and the requests were imperatives with semantic aggravators, embedded imperatives, or permission directives with semantic softeners. Subjects rated the speakers with respect to how rude/polite, humble/arrogant, and powerful/weak they were being. Significant interactions were obtained for the first two ratings, indicating that the speaker status effect was stronger with permission directives than with the other requests. These findings suggest that listeners view unexpectedly indirect requests as more impolite and sarcastic than requests used in other situations and, more generally, that language meaning is a function of both form and context.     

Heart attack risk perception biases among hypertension patients: the role of educational level and worry

Risk biases such as comparative optimism (thinking one is better off than similar others) and risk inaccuracy (misestimating one's risk compared to one's calculated risk) for health outcomes are common. Little research has investigated racial or socioeconomic differences in these risk biases. Results from a survey of individuals with poorly controlled hypertension (N=813) indicated that participants showed (1) comparative optimism for heart attack risk by underestimating their heart attack risk compared to similar others, and (2) risk inaccuracy by overestimating their heart attack risk compared to their calculated heart attack risk. More highly educated participants were more comparatively optimistic because they rated their personal risk as lower; education was not related to risk inaccuracy. Neither race nor the federal poverty level was related to risk biases. Worry partially mediated the relationship between education and personal risk. Results are discussed as they relate to the existing literature on risk perception.
