Threat interpretation in anxious children and their mothers: comparison with nonclinical children and the effects of treatment

Interpretation biases towards threat play a prominent role in cognitive theories of anxiety, and have been identified amongst highly anxious adults and children. Little is known, however, about the development of these cognitive biases although family processes have been implicated. The current study investigated the nature of threat interpretation of anxious children and their mothers through (i) comparison of a clinic and non-clinic population, (ii) analysis of individual differences; and (iii) pre- and post-treatment comparisons. Participants were 27 children with a primary anxiety disorder and 33 children from a non-clinic population and their mothers. Children and mothers completed self-report measures of anxiety and indicated their most likely interpretation of ambiguous scenarios. Clinic and non-clinical groups differed significantly on measures of threat interpretation. Furthermore, mothers' and children's threat interpretation correlated significantly. Following treatment for child anxiety, both children and their mothers reported a reduction in threat interpretation.     

Cross-cultural Differences in Self-reported Decision-making Style and Confidence

The Melbourne Decision Making Questionnaire (Mann, Burnett, Radford, & Ford, 1997) measures self-reported decision-making coping patterns. The questionnaire was administered to samples of University students in the US (N = 475), Australia (N = 262), New Zealand (N = 260), Japan (N = 359), Hong Kong (N = 281), and Taiwan (N = 414). As predicted, students from the three Western, individualistic cultures (US, Australia, and New Zealand) were more confident of their decision-making ability than students from the three East Asian, group-oriented cultures (Japan, Hong Kong, Taiwan). No cross-cultural differences were found in scores on decision vigilance (a careful decision-making style). However, compared with Western students, the Asian students tended to score higher on buck-passing and procrastination (avoidant styles of decision making) as well as hypervigilance (a panicky style of decision making). Japanese students scored lowest on decision self-esteem and highest on procrastination and hypervigilance. It was argued that the conflict model and its attendant coping patterns is relevant for describing and comparing decision making in both Western and Asian cultures.     

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.     

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.     

Reward dominance and passive avoidance learning in adolescent psychopaths

This study tests predictions that adolescent psychopaths are hyperresponsive to rewards (Quay, 1988) and deficient in passive avoidance learning (Newman & Kosson, 1986). Forty male adolescent juvenile offenders were divided into psychopaths and nonpsychopaths using cluster analysis. Subjects were administered a passive avoidance learning task which required learning when to respond to cards associated with either reward or punishment. Results showed a greater responsivity to reward in psychopaths, with no group differences in passive avoidance errors. Results lend support to the view that psychopaths tend to focus on the prospect of reward under conditions of mixed incentives and, when sufficiently motivated, are capable of improved performance. Together with findings of recent psychophysiological studies, these results suggest that adolescent psychopaths may have latent abilities which could have treatment implications.The authors are greatly indebted to the boys and staff of the testing institution for their kind cooperation in this study. Thanks are also due to Dr. Rand Wilcox for statistical consultation and Cheryl Eurton and Marni Ayers for assistance in data coding.     

Stimulus complexity and information integration in the spontaneous interpretations of line graphs

Viewers of a graph will readily interpret its contents, even when given no explicit instructions regarding what information to extract. However, little is known about the strategies that subjects adopt when making such spontaneous interpretations. In the present experiments, subjects studied single-function line graphs for self-determined periods. They provided written interpretations immediately following examination of each graph. The structural complexity of stimulus graphs was varied by eliminating symmetry, and by adding data points, departures from linearity, and trend reversals. Across two experiments, number of trend reversals was the main determinant of comprehension difficulty as measured by study times. An increased number of reversals also resulted in more local, detail-oriented content in interpretations. By contrast, the presence of such emergent features as symmetry and linearity led to increases in the amount of integrative, global content in interpretations, usually at the expense of local detail. Surprisingly, increases in the number of data points led to similar increases in the grain of subjects' interpretations. The last finding may reflect a shift from point-by-point to integrative study strategies necessitated by capacity limitations in working memory.
