Artistic style and personality in creative painters

The present study attempted to demonstrate a correspondence between artistic style and the personality of the creator. Personality style, defined as a cognitive-affective system of defenses and controls, was identified for 20 renowned painters through an analysis of their individual Rorschach protocols. Their creative work was classified independently by a jury of 4 persons (one art critic; two eminent painters and the junior author) into stylistic categories similar to those elaborated by the senior author for the Rorschach. The overall correspondence achieved was statistically significant (.72, p < .01), with individual correlations ranging from .75 to .86 (p < .01).     

The intuitive personologist revisited: A critique of dialectical person perception

A critical examination of dialectical person perception as advanced by Lamiell, Foss, Trierweiler, and Leffel, (1983) reveals some important problems both in its empirical basis and in the underlying model of the intuitive personologist. The present article discusses these problems and suggests some alternative conceptions of the intuitive personologist.     

Discrimination and generalization by rats of temporal stimuli lasting for minutes

In three experiments, rats learned to respond differentially to reinforced and nonreinforced trials when the length of the intertrial interval (ITI) predicted the trial outcome (reinforcement or nonreinforcement). Rats in control groups, for whom the length of the ITI did not predict the outcome, did not show differential performance on nonreinforced and reinforced trials. Generalization gradients obtained following discrimination training were comparable to those obtained following discrimination training with other types of discriminative stimuli. That is, groups which had shown differential performance in discrimination training yielded generalization gradients with fastest speeds at the previously reinforced ITIs, slowest speeds at the previously nonreinforced ITIs, and intermediate speeds at ITIs of intermediate length. Control groups yielded flat gradients across all ITIs tested. These effects were shown for relative time discrimination (short time = reinforcement, long time = nonreinforcement, or the reverse) and also for an absolute time discrimination (long and short time = reinforcement, middle time = nonreinforcement or the reverse). This method was effective for time duration measured in minutes rather than seconds, as is more commonly the case.     

Vicarious and operant experiences in the etiology of illness behavior: A replication with healthy individuals

The purpose of the present investigation was to replicate a previous study of diabetic patients on the role of parental modeling in the etiology of illness behavior. A random sample of healthy individuals were assigned to an avoidant model (AM) (i.e. parent reported to have avoided work. chores etc. when ill) or non-avoidant model (NAM) group. Subjects subsequently provided retrospective and current information concerning their illness-behavior experiences. The results indicated that individuals with an AM reported more responsibility avoidance when ill currently and as a child compared to the NAM subjects. Additionally. AM subjects reported receiving more positive reinforcement for current illness compared to NAM subjects. It was concluded that the process by which individuals learn to respond to illness may be similar in healthy and chronically-ill individuals but that positive reinforcement for illness may be more likely to be received by healthy individuals during acute illness than by chronically-ill individuals. The present study provides further preliminary support for the learningtheory model of illness behavior.     

The role of marking when reward is delayed

Two-choice spatial discrimination by rats is enhanced if a salient stimulus marker occurs immediately after every choice response and again after a delay interval (Lieberman, McIntosh & Thomas, 1979). Three experiments further explore this effect. Experiment 1 found that the second marker is unnecessary. Experiment 2 found that a marker presented before a response is as effective as one presented after. Both effects could be explained in terms of markers focusing attention on subsequent cues. Experiment 3, however, found that markers after choice enhance learning even when no discriminative cues are present following the marker. Markers thus appear to initiate both a backward search through memory and attention to subsequent events; both processes help to identify events that might be related to the unexpected marking stimulus.     

Voice Identification Over the Telephone1

Following a telephone survey investigating attitudes toward police and frequency of personal victimization. 177 citizens between the ages of 18 and 88 years participated without forewarning in a field study on telephone voice identification. Identification accuracy (hits) improved with longer conversation durations (an average duration of 7.8 min compared to conversation durations of 3.2 min and 4.3 min. on average), but the false alarm rate also reliably increased with longer durations in a target-present lineup. False alarms were consistently high (overall M= .48) in the target-absent lineup. No significant differences were found in hit scores or false alarm scores over a two to three day retention interval. No significant correlation was found between confidence scores and accuracy of performance on the target-present lineup (r= .10). but a significant correlation (r= 36) was found on the target-absent lineup.     

Activity of wrist muscles elicited during imposed or voluntary movements about the elbow joint

To examine the coordination of muscles during multijoint movement, we compared the response of wrist muscles to perturbations about the elbow joint with their activation during a volitional elbow movement. The purpose was to test the following two predictions: (a) Responses can occur in muscles not stretched by the perturbation, as has been reported for other multijoint systems; and (b) the motor pattern in response to a perturbation mimics an opposing volitional motor pattern across the two joints. We recorded the electromyographic (EMG) activity of elbow and wrist muscles as well as the flexion/extension motions at the elbow and wrist joints during individual trials that either involved a response to a torque perturbation that extended the elbow or required volitional elbow flexion. The results of this study confirmed that responses were elicited in the nonstretched wrist muscles when the elbow joint was perturbed. The same motor sequence of elbow and wrist flexors was present for both the volitional and perturbation task (with the forearm supinated), regardless of whether the wrist joint was immobilized or freely moving. The findings suggest that the nervous system relies on the purposeful coupling of elbow and wrist flexors to counter the inertial effects during the unrestricted voluntary movement, even though the coupling does not appear to be purposeful during the perturbation or with the wrist immobilized. The coupling of elbow and wrist flexors, however, was not rigidly fixed, as evidenced by muscle onsets that adapted over repeated perturbation trials and a reversal of the wrist muscle activated (wrist extensor) when the forearm was pronated. Hence, the coupling of muscle activities can be modified quantitatively when not beneficial and can be altered qualitatively with different initial configurations of the arm.     

Manifest needs of prospective counselors: a comparative study

Mean performances of 81 prospective counselors on each of the Edwards Personal Preference Schedule (EPPS; Edwards, 1959) needs were analyzed and statistically compared with performances of elementary school counselors, other school counselors, urban college students, professional women, Roman Catholic sisters, and the 1959 EPPS norm samples. Performances of the men and women in the prospective counselor group were similar. Men had a significantly higher need for achievement and dominance, but the significance did not reach .01. Two EPPS needs, intraception and nurturance, consistently differentiated the prospective counselor group. Comparisons across samples indicated that prospective counselors were most similar to the two counseling samples and, for the female subgroup of prospective counselors, to the sample of professional women. Largest across-sample differences were found between the female prospective counselors and the Roman Catholic sisters, between the female prospective counselors and norm samples of female college students and female adults, and between the male prospective counselors and the male adult norm sample.     

The knowledge and use of quantitative research by pastoral counselors

This study investigated the degree of training, experience and interest in quantitative research among pastoral counselors. It was found that a little over half of the subjects had had at least one statistics course and thought that research was valuable. However, less than 6% had ever published research and only one subject (less than 1%) had published more than two quantitative articles. This suggests there is a research vacuum in the field of pastoral counseling. There is no scientific core of scholars publishing a systematic program of research. Recommendations for ways to involve pastoral counselors more actively in research are made.New Perspectives, Owings Mills, MD.
