A Rorschach investigation of mothers of behaviorally disturbed infants

This investigation focuses on one facet of the interactional family, parent-child, mother-infant matrix of behaviorally disturbed infants: the personality of mother as primary caregiver. Rorschach test behavior of mothers (N = 30) of behaviorally disturbed infants were compared with two normative samples. The Rorschach test was found to indicate certain atypical psychological patterns among these mothers. Differences emerged in intellectual sphere variables: number of responses (R), common detail responses (D), rare detail responses (Dd), number of accurate form percepts (F+), percentage of form percepts that are accurate (F+%), percentage of responses with animal content (A%), and popular percepts (P). Other response trends emerged in the affective sphere: percentage of pure form responses (F%) and in the interpersonal sphere: whole human content (H) and the ratio of the whole human content to human detail content (H:Hd), as well as to the test as a whole. Based on these results, hypotheses are generated for further investigation, particularly of traits in the areas of cognitive processing and the capacity for interpersonal relations.     

The interaction between stimulus and reinforcer control on remembering.

In a symbolic matching-to-sample task, 6 pigeons obtained food by pecking a red side key when the brighter of two white lights had been presented on the center key and by pecking a green side key when the dimmer of two white lights had been presented on the center key. Across Part 1 and Parts 6 to 10, the delay between sample-stimulus presentation and the availability of the choice keys was varied between 0 s and 25 s. Across Parts 1 to 5, the delay between the emission of a correct choice and the delivery of a reinforcer was varied between 0 s and 30 s. Although increasing both types of delay decreased stimulus discriminability, lengthening the stimulus-choice delay produced a greater decrement in choice accuracy than did lengthening the choice-reinforcer delay. Additionally, the relative reinforcer rate for correct choice was varied across both types of delay. The sensitivity of behavior to the distribution of reinforcers decreased as discriminability decreased under both procedures. These data are consistent with the view, based on the generalized matching law, that sample stimuli and reinforcers interact in their control over remembering.     

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.     

Acquisition and transfer of occasion setting in operant feature positive and feature negative discriminations

The acquisition and transfer of stimulus control in discrete-trial operant feature positive and feature negative discriminations was examined in two experiments with rats. When the feature and target cues were presented simultaneously on compound training trials, the feature appeared to acquire simple excitatory or inhibitory control, which readily transferred to other target cues and which was substantially reduced by post-training counterconditioning. Conversely, when the feature preceded the target during training, the feature's control was relatively more specific to responding in the presence of its original target and less influenced counterconditioning. These results are comparable to outcomes of analogous experiments (previously reported) that used Pavlovian conditioning procedures.     

An heuristic for the study of the effects of emotion on memory

This report contains an heuristic (a systematic set of questions) addressing issues of concern in the emotion-memory literature. Four experiments (ns of 73, 24, 160, and 34) are described in terms of the heuristic and its potential for describing the literature is examined.     

Equivalence of Peabody Picture Vocabulary Test--Revised, forms L and M for children with acquired immune deficiency syndrome (AIDS)

The purpose of this preliminary investigation was to assess the equivalence of Forms L and M of the Peabody Picture Vocabulary Test--Revised for a sample of 15 Hispanic and 12 black children diagnosed as having Acquired Immune Deficiency Syndrome (AIDS). The children (15 boys, 12 girls) were administered PPVT-R Forms L and M in counterbalanced order and in immediate succession. The coefficient of equivalence, r, was .77 and significant. Influential factors, such as the behavioral manifestations of AIDS, are discussed. Limitations of the study are included. Research should focus on the long- and short-term stability of the test for these children as they are evaluated repetitively.     

Accuracy of weightbearing at three target levels during bilateral upright stance in patients with neuropathic feet and control subjects

The purposes of this study were to (1) describe errors in weightbearing at three target levels for patients with neuropathic feet and control subjects, (2) compare the absolute errors at the three target levels between groups, and (3) identify predictor variables of errors in weightbearing by the neuropathic group. The groups of 26 subjects were matched for age and height. Weightbearing was measured with digital scales while subjects attempted to adjust their weight through a designated lower extremity to each target level (25, 50, and 75% of body weight). Analysis of variance indicated no significant difference in the percentage weightbearing between groups at the three target levels. There was a significant difference in errors made in weightbearing by the groups at the three target levels. Mean errors ranged from 8.5 to 9.7% for the neuropathic group and from 2.4 to 6.6% for the control group. The findings cast doubt on the utility (in the absence of feedback) of requesting individuals, particularly those with neuropathic feet, to weightbear at specific target levels.     

Perceptions of current and ideal body shape of athletes and nonathletes

This study was done to examine the relationship between sex and perception of body image among athletes and nonathletes. A total of 211 men and women athletes and nonathletes completed a questionnaire which asked them to identify from a nine-figure body-silhouette scale their current image and the image that they thought was most ideal. t tests showed no significant differences for men based upon athletic participation and that both athletes and nonathletes were satisfied with their body image. However, when comparing current image and ideal image, significant differences were found for women athletes and nonathletes. These data support previous research documenting women's dissatisfaction with their body images and show athletic participation is not associated with this perception.     

Tactile attention and the perception of moving tactile stimuli

Three experiments investigated the ability of subjects to identify the direction of movement of a pattern across the skin. In Experiments 1 and 2, subjects were required to identify the direction of movement of a pattern presented to one fingerpad while another moving pattern was being presented to an adjacent fingerpad. Subjects were instructed to attend only to the target location. The results showed that accuracy was consistently higher and reaction times were consistently faster when the two patterns moved in the same direction than when they moved in opposite directions. Both effects were largest when the two patterns were presented simultaneously. In Experiment 3, the nontarget location was the contralateral hand. In this case, performance was not affected by the presentation of the nontarget. Combined, the results suggest that movement information is processed across adjacent fingers even when subjects are explicitly instructed to attend only to one finger. Subjects do appear to be able to restrict attention to a single hand.     

Visible persistence following a brief increment in stimulus luminance

In previous studies, it has been demonstrated that visible persistence--the period for which the perceived duration of a stimulus exceeds its physical duration--can be extended by briefly incrementing the luminance of the stimulus immediately prior to offset. Using a two-component pattern integration task, we show that this effect is not an artifact of change in the total luminous flux within the stimulus. Visible persistence was unaffected by overall luminance of the stimulus. It was also time-locked to the luminance increment. Visible persistence is seen to result from a process that is initiated by stimulus onset and that can be either wholly or partially reinitiated by the onset of the luminance increment. The duration of this process (which determines the duration of stimulus visibility) can be modified in a graded fashion by stimulus events that occur after its initiation. We outline a single-process inhibitory feedback model of the persistence mechanism that accounts for the present findings.
