The role of dynamic information in the recognition of unfamiliar faces

The effects of movement on unfamiliar face recognition were investigated. In an incidental learning task, faces were studied either as computer-animated (moving) displays or as a series of static images, with identical numbers of frames shown for each. The movements were either nonrigid transformations (changes in expression) or rigid rotations in depth (nodding or shaking). At test, participants saw either single, static images or moving sequences. Only one experiment showed a significant effect of study type, in favor of static instances. There was no additional advantage from studying faces in motion in these experiments, in which both study types showed the same amounts of information. Recognition memory was relatively unaffected by changes in expression between study and test. Effects of viewpoint change were large when expressive transformations had been studied but much smaller when rigid rotations in depth had been studied. The series of experiments did reveal a slight advantage for testing memory with moving compared with static faces, consistent with recent findings using familiar faces. Future work will need to examine whether such effects may also be due to the additional information provided by an animated sequence.     

Psychological Effects of a Life Review Intervention for Persons With HIV Disease

The purpose of this study was to evaluate a life review intervention for persons with HIV disease. Twenty-seven adults with HIV disease (16 had been diagnosed with AIDS) were randomly assigned to 1 of 3 conditions: a group life review intervention (n = 8), a traditional support group (n = 9), or a waiting list (n = 10). Using a pre-post design, participants were compared on psychological measures of optimism, self-esteem, purpose in life, coping ability, psychological distress, and death anxiety. Although analyses revealed no significant differences between the interventions, statistical trends and participants' written evaluations favored the life review intervention. Attrition was a significant problem. Discussion focuses on the special problems encountered in conducting psychological intervention research with an HIV-positive population.

Access to Categories of Experience and Mental Health in a Sample of Managers

This study of 28 managers investigated the importance for mental health of Jahoda's (1982) five categories of experience, measured for both work and leisure. Each of the categories of experience of time structure, social contact, collective purpose, status, and activity correlated with at least one measure of mental health. Multiple regression analysis showed that collective purpose and status, in both work and leisure, had moderate to large β coefficients, indicative of their potential influence, for a range of measures of mental health, covering positive mental health and freedom from negative mental health. Analyses of Warr's (1987) nine "principal environmental influences" (PEI) also supported the importance of collective purpose and status. This showed that the PEI "valued social position," which includes these two categories of experience, remained significantly associated with several measures of mental health. Analysis of the PEIs also showed that opportunity for use of existing skills in leisure, and variety in leisure, were significantly associated with several measures of mental health. The importance of valued social position and active leisure for the well-being of managers is discussed.     

Electrophysiologic Manifestations of Impaired Temporal Lobe Auditory Processing in Verbal Auditory Agnosia

The present study examined the extent to which verbal auditory agnosia (VAA) is primarily a phonemic decoding disorder, as contrasted to a more global defect in acoustic processing. Subjects were six young adults who presented with VAA in childhood and who, at the time of testing, showed varying degrees of residual auditory discrimination impairment. They were compared to a group of young adults with normal language development matched for age and gender. Cortical event-related potentials (ERPs) were recorded to tones and to consonant-vowel stimuli presented in an "oddball" discrimination paradigm. In addition to cortical ERPs, auditory brainstem responses (ABRs) and middle latency responses (MLRs) were recorded. Cognitive and language assessments were obtained for the VAA subjects. ABRs and MLRs were normal. In comparison with the control group, the cortical ERPs of the VAA subjects showed a delay in the N1 component recorded over lateral temporal cortex both to tones and to speech sounds, despite an N1 of normal latency overlying the frontocentral region of the scalp. These electrophysiologic findings indicate a slowing of processing of both speech and nonspeech auditory stimuli and suggest that the locus of this abnormality is within the secondary auditory cortex in the lateral surface of the temporal lobes.     

College Dropouts: Dismissed vs. Withdrew

This study investigated the effect of classifying under the common category of “dropout” both those students who are dismissed for academic reasons and those who withdraw voluntarily. Two groups of college dropouts, namely the dismissed and those who withdrew, were compared with a control group of persevering students in performance on cognitive and personality measures. The two groups were found to differ in an inverse relationship on several sets of measures, thus demonstrating differences in intellectual ability and personality characteristics.     

Religious belief,values, and psychotherapy

Conclusion Conflicts between religious values, personal needs, and the demands of society are inevitable in the lives of all. The healthy person is able to resolve these conflicts, or he learns to live with them. The unhealthy person incorporates them into his neurotic personality. They can become such as to block all progress in therapy. Unless they are handled in some direct fashion, the patient may never attain that inner freedom needed to reorient his distorted values and ideals. In some cases, therefore, the therapist may be forced to take an open approach to religious and moral values, even if this means influencing the patient's values in the direction of the therapist's value system.     

Evoked potentials and stages of information processing: Methods of analysis

The use of principal components analysis (PCA) for the study of evoked-response data may be complicated by variations from one trial to another in the latency of underlying brain events. Such variation can come from either random intra-and intersubject variability or from the effects of independent variables that are manipulated between conditions. The effect of such variability is investigated by simulation of these latency-varying events and by analysis of evoked responses in a behavioral task, the Sternberg memory search task, which is well known to generate variation in the latency of brain events. The results of PCA of within-subjects differences in these two situations are plausibly related to underlying stages of information processing, and the technique may augment reaction time data by providing information on the time of occurrence as well as the duration of stages of information processing.     

Repeated acquisition in the analysis of rule-governed behavior

Five children, ranging in age from 3½ years to 5½ years, were taught various four-response chains using conditioned reinforcement. Experiment 1 investigated the effects of presenting “instruction” stimuli—a sequence of lights over the correct response buttons—to assess their role in facilitating the acquisition of a chain of responses. Without the “instruction” stimuli, children made many errors before responses were brought under the control of the programmed contingencies. When confronted with the same contingencies later in the day, these subjects made fewer errors. In contrast, in the presence of the “instruction” stimuli, subjects made virtually no errors. However, when the “instruction” stimuli were discontinued in the subsequent session, all 5 subjects made errors. In Experiment 2, the subjects were taught to verbalize the contingencies during the phase without the “instruction” stimuli. This resulted in errorless performance during the subsequent exposure to the same procedure, but errors nevertheless occurred again during reexposure to the procedure with the “instruction” stimuli discontinued.     

Choice: A local analysis

Analyses of free-operant choice usually employ one of two general procedures: the simple concurrent procedure (i.e., a concurrent variable-interval variable-interval schedule) or the concurrent-chains procedure (i.e., concurrently available initial links, each leading to an exclusively available terminal link). Theories about choice usually focus on only one of the two procedures. For example, maximization theories, which assert that behavior is distributed between two alternatives in such a way that overall rate of reinforcement is maximized, have been applied only to the simple concurrent procedure. In the present paper, a form of the pairing hypothesis (according to which pairings between one stimulus and another affect the value of the first, and pairings between responses and reinforcers affect the value of the former) is developed in a way that allows it to make qualitative predictions with regard to choice in a variety of simple concurrent and concurrent-chains procedures. The predictions include matching on concurrent variable-interval variable-interval schedules, preference reversal in the self-control paradigm, and preference for tandem over chained terminal links.
