Mothers' psychological adjustment following disaster affecting their children

The authors investigated the psychological adjustment of 37 British women whose adolescent children survived the cruise ship Jupiter's sinking in 1988, about 6 years previously. They compared these women with a group of widows (N = 18) and a group of women who had suffered no major negative life event (N= 15). Psychological adjustment of the 37 women was assessed with the Schedule for Affective Disorders and Schizophrenia Lifetime Version (SADS-L; R. L. Spitzer & J. Endicott, 1975) and various standard questionnaires. The women whose children had been involved in the disaster were found to have suffered a greater number of incidents of psychological distress in the period since the disaster than the women who had suffered no major negative life events but fewer incidents of psychological distress than the widows. The significance of these findings and clinical implications are discussed.     

The Nature of Generalized Anxiety in Older Primary Care Patients: Preliminary Findings

Clinical features of older primary care patients with GAD (PC-GAD; n = 22) were examined relative to older patients with GAD recruited for two academic clinical trials (M. A. Stanley, J. G. Beck, et al., 2003; J. L. Wetherell, M. Gatz, & M. G, Craske, 2003) and to a sample of older primary care patients without psychiatric diagnoses (No Dx; n = 10). Comparisons revealed similar levels of worry, anxiety, depressive symptoms, quality of life, and functional status between the PC-GAD subsample and patients recruited for academic trials, although primary care patients were older, less well educated, and more ethnically diverse. The PC-GAD subgroup, however, reported greater symptom severity, reduced quality of life, and poorer perceived general health, mental health, and vitality than the No Dx subgroup (² = .23–.43). Service utilization was not different between PC-GAD and No Dx subgroups, with the exception of psychotropic medication use. The Penn State Worry Questionnaire (PSWQ) and an abbreviated version of this measure may be useful for identifying late-life GAD in primary care. Cutoff scores of 50 and 22 on the full and abbreviated versions of the PSWQ, respectively, demonstrated excellent specificity, sensitivity, and positive predictive value. Negative predictive value was less impressive, probably as a result of high base rates for GAD in this sample.     

Personality and executive functioning as risk factors in recidivists

The classification of an inmate population at a maximum security jail in Canada was undertaken to study factors correlated with recidivism. A total of 12 recidivists and 12 nonrecidivists were classified according to their index offenses, and a Criminal Record search was completed to verify their statements. A total of 15 non-offenders who had also undergone a criminal record check were included as controls. All participants were administered the Minnesota Multiphasic Personality Inventory-168, Violence Risk Scale-Experimental Version, Coopersmith Self-esteem Inventory, and the Wisconsin Card Sorting Task. Statistical analysis showed significant differences between the groups on scores for the Hypochondriasis, Psychopathic Deviate, and Hypomania scales of the MMPI-168. Significant differences were noted for the Wisconsin Card Sorting Task and the Violence Risk Scale. Discriminant analysis of the recidivists and nonrecidivists correctly classified at a 91.3% level.     

Meme Pools, World 3, and Averroës's Vision of Immortality

Dawkins's concept of the meme pool, essentially equivalent to Popper's World 3, is considered as an expression in modern terms for what Averroës knew as the active intellect , an immortal entity feeding into, or even creating, the passive intellect of consciousness. A means is thus provided for reconciling a materialist Darwinian view of the universe with a conception of nonpersonal immortality. The meme pool/active intellect correspondence provides a strong basis for regarding science as a communal enterprise producing enrichment of the meme pool and expansion of consciousness. It also emphasizes the virtues of memetic conservation in relation to vanishing cultures.     

Politics and participation: Some antecedents of young people's attitudes to the political system and political activity

The antecedents of political disaffection and political activism have been extensively studied in adult populations, producing two models of political protest, the ‘dissatisfaction model’, suggesting that protest action is rooted in political disaffection, and the ‘resource model’ which bases interest in politics in a sense of political self-efficacy. There has been a dearth of research extending this theorizing to young people of prevoting age. The present study presents the results of regression analysis applied to longitudinal data collected in a U.K. Programme of research and economic and political socialization, the ESRC 16-19 Initiative. The analysis relates ‘lack of interest in politics’, ‘intention not to vote’ and ‘political activity’, to attitudes, personality characteristics, experience and circumstances measured earlier. It is concluded that political disaffection including lack of interest and intention not to vote, is strongly associated with a growing cynicism about politics rooted in poor educational performance and a working class family background. The connections with activism are negative but much weaker, suggesting the potential for protest activity across a wider spectrum of youth. This lends support to Marsh's (1990) view that given the right circumstances, protest action under both the ‘resource model’, and the ‘dissatisfaction model’, can apply.     

Effects of self-control training for elementary students with emotional and behavioral disorders

Progressive delay training (PDT) has been used to promote self-controlled choices (i.e., selecting a larger, later reward over a smaller, immediate reward) for people with a variety of developmental characteristics. However, the efficacy of PDT has not been evaluated in children with emotional and behavioral disorders (EBD), who often have co-occurring symptoms of impulsivity. The purpose of this study was to evaluate the effects of PDT with a rule-following requirement on the impulsive choices of 6 elementary students with EBD using a modified changing criterion design. Results indicated that PDT alone did not improve self-control, but a modified version of PDT with a rationale and rule for selecting the delayed reward promoted self-control for 3 participants. The remaining 3 participants continued to make impulsive choices despite further modifications to the PDT protocol. We discuss implications of our results and directions for future research on treating impulsivity in children with EBD.     

Integration of intermittent visual samples over time and between the eyes

The authors investigated the integration of alternate disparate monocular inputs for binocular perception in 1-handed catching experiments (N = 14, 32, 22, and 15 participants, respectively in Experiments 1-4). They varied the no-vision interval between alternate monocular samples to measure catching performance, and they compared the alternating monocular conditions with binocular and monocular conditions with equal no-vision intervals. They found no evidence of a binocular advantage for one-handed catching in the alternating monocular conditions. Performance in monocular and alternating monocular conditions did not differ across no-vision intervals ranging from 0-80 ms and was particularly worse than performance in binocular viewing conditions when the no-vision interval was 40 ms or more. The authors argue that the dissimilarity between disparate monocular inputs created by the approaching object limited the integration of those inputs and subsequent binocular perception.     

Neighborhood effects in reading aloud: new findings and new challenges for computational models

A word from a dense neighborhood is often read aloud faster than a word from a sparse neighborhood. This advantage is usually attributed to orthography, but orthographic and phonological neighbors are typically confounded. Two experiments investigated the effect of neighborhood density on reading aloud when phonological density was varied while orthographic density was held constant, and vice versa. A phonological neighborhood effect was observed, but not an orthographic one. These results are inconsistent with the predominant role ascribed to orthographic neighbors in accounts of visual word recognition and reading aloud. Consistent with this interpretation, 6 different computational models of reading aloud failed to simulate this pattern of results. The results of the present experiments thus provide a new understanding of some of the processes underlying reading aloud, and new challenges for computational models.     

On the practice of dichotomization of quantitative variables

The authors examine the practice of dichotomization of quantitative measures, wherein relationships among variables are examined after 1 or more variables have been converted to dichotomous variables by splitting the sample at some point on the scale(s) of measurement. A common form of dichotomization is the median split, where the independent variable is split at the median to form high and low groups, which are then compared with respect to their means on the dependent variable. The consequences of dichotomization for measurement and statistical analyses are illustrated and discussed. The use of dichotomization in practice is described, and justifications that are offered for such usage are examined. The authors present the case that dichotomization is rarely defensible and often will yield misleading results.     

Turning a deaf ear to fear: impaired recognition of vocal affect in psychopathic individuals

The processing of emotional expressions is fundamental for normal socialization and interaction. Reduced responsiveness to the expressions of sadness and fear has been implicated in the development of psychopathy (R. J. R. Blair, 1995). The current study investigates the ability of adult psychopathic individuals to process vocal affect. Psychopathic and nonpsychopathic adults, defined by the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991), were presented with neutral words spoken with intonations conveying happiness, disgust, anger, sadness, and fear and were asked to identify the emotion of the speaker on the basis of prosody. The results indicated that psychopathic inmates were particularly impaired in the recognition of fearful vocal affect. These results are interpreted with reference to the low-fear and violence inhibition mechanism models of psychopathy.
