Matching behavior: Some methodological problems

Two classes of problems associated with specifying the controlling stimuli in matching experiments were discussed. The first class-control of matching behavior by cues other than the standard stimuli-was demonstrated by the results of a pseudomatching experiment. The second class related to the “effective” sample or standard stimulus set and to changes in the S’s matching strategy that may occur in a matching experiment.     

Reflections on thomism and client-centered psychotherapy

Conclusion To summarize, Rogers and Aquinas both stress the importance of existential experience and sense data. Although Rogers is more concerned with human freedom and being than are many modern adjustment psychotherapists, he is still circumscribed by his initial positivistic assumptions about the nature of man in his therapy. but these assumptions may be in the process of change.But like Aquinas, Rogers has a deep respect for the person, a respect for his emotions, a respect for his whole existential being.³⁸ Rogers once stated that the client-centered point of view is devoid of thequid pro quo aspect of most experiences we call love. It is the simple outgoing human feeling of one individual for another, a feeling it seems ... which is even more basic than sexual or parental feelings. It is a caring enough about the person that you do not wish to interfere with his development, nor to use him for any self-aggrandizing goals of your own. Your satisfaction comes in having set him free to grow in his own fashion.³⁹ Isn't this the spiritual detachment of real Christian love?He has taught at the University of California at Los Angeles and at Loyola University (Los Angeles), and has been a staff psychologist at the Metropolitan State Hospital, Los Angeles. He is a member of the American Psychological Association and the American Academy of Psychotherapists.Portions of this paper were presented at the 16th Annual Scientific Session, Guild of Catholic Psychiatrists, Los Angeles, 1964.     

The effects of stimuli followed by response-independent shock on shock-avoidance behavior

Four rhesus monkeys were trained on a non-discriminated shock-avoidance schedule (baseline). Stimuli followed by response-independent shock were then presented with the avoidance baseline no longer in effect. The main portion of the experiment consisted of superimposing (independently of responding) the stimuli followed by response-independent shock on the avoidance baseline. Different temporal values of stimulus duration and delay of shock (produced by an avoidance response) were presented successively, using each subject as his own control. When the stimulus duration was short or the delay of shock was long, so that avoidance rate during the stimulus could assume any value without resulting in baseline (avoidable) shocks during the stimulus, a lowered or "suppressed" rate of responding developed during the stimulus. When the stimulus duration was long or the delay of shock was brief, so that avoidable shocks resulted from a response decrement during the stimulus, high or "facilitated" rates of responding developed for a large proportion of the time that the stimulus was present.

Visual recognition thresholds and dimensions of word meaning

Tachistoscopic recognition thresholds were obtained for nouns with high or low values on one dimension of meaning while two others were controlled. Frequency, imagery concreteness (I), and meaningfulness (m), were varied in different lists in one experiment, frequency and m in a second, and m alone in a third. Ratings of familiarity were also obtained to supplement frequency as a measure of familiarity. The results showed that ease of visual recognition was most strongly related to frequency and familiarity. Imagery was unrelated to thresholds when familiarity and m were controlled. Meaningfulness showed a small but consistent positive relation to ease of recognition even with the other variables held constant. Except for the puzzling effect of m, the results are consistent with the view that perceptual recognition is primarily dependent upon the familiarity of the target stimulus and not upon associative processes evoked by it.     

An assessment of manager/subordinate perceptions of performance appraisal effectiveness

This study postulates that performance appraisal will be effective to the extent that managers and subordinates have a shared perception of its purpose and function and the degree to which it meets the needs of both groups. A two part research project was conducted to: 1) identify manager/subordinate perceptions of the purposes served by the formal performance appraisal process; 2) determine the extent to which these purposes are being satisfied in organizational practice; and 3) assess if managers and subordinates have a shared perception of the effectiveness of the appraisal process. The sample for the study included 36 managers and 143 subordinates from a division of a large Midwest service organization. The results were mixed with regard to the appraisal system effectively accomplishing its diverse goals. However, in general, there was support for the notion that both managers and subordinates find the appraisal process to be a worthwhile organizational practice. Approximately 70% of the respondents indicated that they would participate in the appraisal program whether they were required to do so or not.     

RWMODEL: A program in Turbo Pascal for simulating predictions based on the Rescorla-Wagner model of classical conditioning

A Turbo Pascal computer program is described that simulates the Rescorla-Wagner model of classical conditioning. The menu-driven program makes it possible to compute associative strengths for differential conditioning, conditioned inhibition, compound and contextual conditionings, trans-switching, and other designs.
