Reliability of self-reported service use: Test-retest consistency of children's responses to the Child and Adolescent Services Assessment (CASA)

This paper reports on the reliability of children's responses on the Child and Adolescent Services Assessment (CASA) — a self-report instrument for use with 8– to 18-year-olds that gathers information about services used to address mental health problems. Findings were based on interviews completed by 77 children at a one week test-retest interval. Results showed that reports of lifetime service use were as reliable as were reports of service use in the preceding three months. Children reported restrictive and intrusive services more reliably than services that were provided in their natural environment. Reliability appeared to be associated more strongly with characteristics of the type of service than with characteristics of the child. Children also could report reliably on some details about their encounters with service providers (e.g., length of stay, number of visits, and onset of service use).     

A repertory grid study of therapist/couple interaction

A case of marital therapy is described in which the presenting problem, one of non-consummation, is treated by the standard Masters and Johnson's technique. Using repertory grids at the start and finish of treatment the changing perceptions of both partners and the therapist were determined. In spite of an ostensibly behavioural treatment, substantial changes occurred in the couple's understanding of the nature of their problem. The changes undergone in the couple's perceptions, and their differences from the therapist's assessments of change give rise to speculations about the nature of the therapeutic interaction and suggest further lines of exploration.     

The effect of modification of expressive displays on vicarious emotional arousal

Several recent experiments have demonstrated that modulation of the facial expressive response is accompanied by changes in autonomic arousal and subjective response to painful stimuli. The present study asked whether facial self-regulation may also bring about changes in covert vicarious emotional experience. Three groups of subjects were exposed to a videotaped model displaying intermittent pain to shock in a differential vicarious autonomic conditioning paradigm. Subjects in the inhibit and amplify groups were asked, respectively, (a) to inhibit their facial muscles or (b) to pose a facial response of pain when the model was shocked. It was predicted that the inhibit group would show less autonomic arousal to the model's expressive display (empathy) and less conditioning (as measured by skin conductance and heart rate change), and the amplify group more empathy and conditioning, than a third group who was given no facial instruction. In fact, the amplify group showed more skin conductance arousal, heart rate acceleration, and activity in response to the model's expressive display of pain than did the other two groups (which were not different from each other), but no more autonomic or facial conditioning. The overall pattern of physiological data is interpreted as generally supportive of a facial feedback theory of emotion: where significant between-groups' differences were obtained in facial activity, as in vicarious instigation, autonomic arousal differences also emerged; where no expressive differences were obtained, as in vicarious conditioning, no differences in autonomic arousal were found.     

Circularity in relative pitch judgments for inharmonic complex tones: The Shepard demonstration revisited,again

The Shepard illusion, in which the presentation of a cyclically repetitive sequence of complex tones composed of partials separated by octave intervals (Shepard, 1964) gives the illusion of an endlessly increasing sequence of pitch steps, is often cited as evidence for octave equivalence. In this paper, evidence is presented which demonstrates that this illusion can be produced using (inharmonic) complex tones whose partials are separated by equal ratios other than octaves. Therefore, the illusion is not evidence for octave equivalence.     

Mental shock can produce retrograde amnesia

Subjects in three experiments saw a short film of a mentally shocking event in which a young boy is violently shot in the face. Compared to other subjects who saw a nonviolent version of the same film, those who saw the mentally shocking version showed poorer retention of the details of the film. Retention was poorer whether measured by recognition or recall. Furthermore, impaired memory occurred only when the event was mentally upsetting, and not when it was merely unexpected but not upsetting. These results suggest that mentally shocking episodes may disrupt the lingering processing necessary for full storage of information in memory.     

The salience of the self in responses to inequity

Previous research has shown that people strive to conform with the standards of significant others in distributive justice. The present research was concerned with the role of attention to the self in the same paradigm. If people are motivated to personally evaluate their own behavior as fair, then self-focus should result in heightened attempts to redress an overpayment inequity. After the subject's criterion of a fair wage was assessed, they were paid either that amount or double it. Orthogonal to this manipulation, subjects were either made objectively self-aware (OSA) or not, by the presence or absence of a mirror. Consistent with the hypothesis, overpaid OSA subjects did more work, but of a poorer quality, than overpaid not-OSA subjects. This was taken as evidence of more zealous attempts to restore a sense of equity, implicating a greater personal need to eliminate the injustice when the discrepancy between pay level and a personal standard of fairness was made more prominent to the self.     

A dual-task analysis of detection accuracy for the case of high target-distractor similarity: Further evidence for independent processing

Previous studies of visual detection performance indicate that perceptual span has a negligible effect on detection accuracy; hence, previous results suggest that individual characters within a multielement array are perceived independently. In this study, additional experimental factors were examined in order to determine whether conditions exist in which perceptual span influences detection performance: targets and distractors were chosen to be maximally similar, and detection accuracy was studied in relation to display size, target redundancy, and homogeneity of distractor characters. To test for perceptual span effects, a three-state model was proposed which incorporates the assumption that individual characters are perceived independently. The model may be applied to (a) both yes-no and forced-choice tasks, and (b) the case when effects of display characteristics differ for response alternatives. Predictions based on the three-state model agree satisfactorily with observed proportions. Moreover, interactions between display characteristics and response alternatives accord well with model predictions, and accuracy differences between subjects are consistent with individual differences in model parameters. The results provide further evidence for the independence assumption and illustrate additional conditions for which perceptual span has a negligible effect on detection accuracy.     

Phonemic behavior of aphasic patients with posterior cerebral lesions

The investigation analyzed the phonemic paraphasic errors of 10 asphasic patients with posterior cerebral lesions. The results indicated that paraphasic speech is characterized by complex confusions, often occurring at the ends of words and often involving phonemic transpositions. Many of the unusual and unexpected phonemic errors appeared to be due to simultaneous semantic and phonologic confusions.
