BIS/BAS responses to emotional cues: Self report, autonomic measure and alpha band modulation

The study explored the effect of the subjective evaluation and of BIS/BAS (Behavioral Inhibition and Activation System) differences on psychophysiological and brain oscillation measures, in response to pleasant/unpleasant and high/low arousing stimuli. Skin conductance response, heart rate, and electromyography, and alpha frequency band, were registered, during viewing IAPS figures. Both BIS and BAS measures were significant in modulating behavioral, autonomic and brain responses, with a clear dichotomy BAS-appetitive/positive BIS-withdrawal/negative sensitivity. Withdrawal (BIS) and appetitive (BAS) behavior showed opposite patterns of responses by the subjects within the frontal cortical site more than other sites. In addition, a specific frontal lateralization effect was found as a function of BIS (more right-side activation for negative cues) and BAS (more left-side activation for positive cues). Moreover, autonomic variables and frequency band were found to be effected by arousal rating per se, with an increased response to high arousal in comparison with low arousal and neutral stimuli. The effects of subjective evaluation and individual differences were discussed in the light of the coping activity of emotion comprehension.     

Ways in which coherence is confirmation conducive

Recent works in epistemology show that the claim that coherence is truth conducive – in the sense that, given suitable ceteris paribus conditions, more coherent sets of statements are always more probable – is dubious and possibly false. From this, it does not follows that coherence is a useless notion in epistemology and philosophy of science. Dietrich and Moretti (Philosophy of science 72(3): 403–424, 2005) have proposed a formal of account of how coherence is confirmation conducive—that is, of how the coherence of a set of statements facilitates the confirmation of such statements. This account is grounded in two confirmation transmission properties that are satisfied by some of the measures of coherence recently proposed in the literature. These properties explicate everyday and scientific uses of coherence. In his paper, I review the main findings of Dietrich and Moretti (2005) and define two evidence-gathering properties that are satisfied by the same measures of coherence and constitute further ways in which coherence is confirmation conducive. At least one of these properties vindicates important applications of the notion of coherence in everyday life and in science.     

Between-measure consistency in social-skills assessment

The purpose of the present study was to assess the between-measure consistency of general and specific social-skills assessment strategies. Nineteen mentally retarded adults were assessed using both common and newly devised measures of social skills: (1) specific (molecular) behavior ratings from role-play assessments, (2) general (molar) ratings based on the role plays, staff (3) molar and (4) molecular predictions of client social skills use in the described role-play situations, (5) peer sociometric ratings, and molecular in vivoobservations conducted in (6) cafeteria and (7) party settings. For all molecular measures, the subjects were assessed on eye contact, response relevance, response latency, voice volume, and appropriate affect, which allowed for direct comparisons to be made between each of these assessment modalities. In addition, the role-play assessment was conducted under two distinct conditions to determine whether role-play performance varied between standard and reinforced administrations; however, multivariate analyses (MANOVA) revealed no differences between the two assessments. Correlations between the molar and the molecular measures suggested a substantial overlap between the measures, with staff ratings having the highest consistency with the other measures. Furthermore, MANOVAs calculated between role-play ratings and those of staff revealed little difference between the two. The limitations on and practical significance of these findings are discussed.     

Assessing the process of desensitization therapy: Five practical measures

Assessment of phobic behavior has included self-report, physiological, and in vivobehavioral measures. While self-report measures are convenient, they suffer from subject bias and a low predictive validity. Physiological and in vivobehavioral measures are often too cumbersome to implement in standard clinical practice. The current study investigated the validity of five convenient measures of phobic behavior during the process of desensitization therapy. Responses of 14 clinically phobic patients were compared on phobic and neutral scenes presented within the context of systematic desensitization therapy. Phobic scenes resulted in less clarity of scene visualization, a longer latency to clear scene visualization, higher subjective units of discomfort (SUDs) at clear visualization, a longer latency to relaxation, and higher SUDs at relaxation. The measures seemed to reflect accurately the process and stages of desensitization therapy and showed low to high intercorrelations. The pragmatic value of these measures is discussed, as well as suggestions for future validational research.     

Development and validation of adolescent-perceived microsystem scales: Social support,daily hassles,and involvement

Developed and validated instruments for urban and culturally diverse adolescents to assess their self-reported transactions with family, peer, school, and neighborhood microsystems for the constructs of social support, daily hassles, and involvement. The sample of 998 youth were from schools in three Eastern cities with high percentages of economically disadvantaged youth. Data were collected before and after the transition to junior high school or to senior high school. Blacks constituted 26%, whites 26%, and Latinos 37% of the sample. Factor analyses confirmed and enhanced the hypothesized four-factor microsystem factor structure for support, hassles, and involvement; internal consistency and stability coefficients were consistent with these structures. In general, the microsystem factors were common across gender, ethnicity, and age. However, when group differences did occur on these demographic variables, they tended to validate the salience of microsystem specificity. In contrast to the total scores, the microsystem-specific factors yielded more meaningful and differential information with regard to demographic differences and the mediating processes across a school transition.     

Impact of the JOBS intervention on unemployed workers varying in risk for depression

Reports the results of the JOBS II randomized field experiment that included a sample of 1,801 recent job losers, 671 of which participated in a modified version of the JOBS I intervention for unemployed workers (Caplan, Vinokur, Price, & van Ryn, 1989). The intervention focused on enhancing the sense of mastery through the acquisition of job-search and problem-solving skills, and on inoculation against setbacks. JOBS II was intended to prevent poor mental health and to promote high quality reemployment. The study tested whether the efficacy of the intervention could be increased by screening and oversampling respondents who were at higher risk for a significant increase in depressive symptoms. Results demonstrated that the intervention primarily benefited the reemployment and mental health outcomes of the high-risk respondents. This suggests the feasibility of enhancing the efficacy of this preventive intervention by targeting, it for high-risk unemployed workers who could be identified prospectively. This research was supported by National Institute of Mental Health Grant No. P50MH38330 to the Michigan Prevention Research Center (Richard H. Price, Principal Investigator).     

Measures of life stress and social support specific to an Asian student population

We designed two new measures—the Index of Life Stress (ILS) and the Index of Social Support (ISS)—to assist in the prediction of cultural adjustment for an Asian international student population. In the present study, these two measures were administered to 101 Asian international students. Stability estimates over 1 month were high: .97 for the ILS and .81 for the ISS. Construct validity, assessed via factor analyses, and concurrent validity, assessed via regression analyses to criteria of depression, hopelessness, and suicide ideation were satisfactory. Incremental validity for these two measures relative to extant measures of life stress and social support were computed. Results from these analyses indicated that these two measures added incrementally to the prediction of adjustment beyond that offered by existing measures.     

A psychometric examination of the multidimensional perfectionism scale

The Multidimensional Perfectionism Scale (MPS), developed by Frost, Marten, Lahart, and Rosenblate (1990), was constructed using an all female sample at an elite university. This study examined the psychometric properties of the instrument using a more typical sample (n=278) of college students from a large state university and a small liberal arts college, both located in the South. Significant differences were found on the overall MPS score as well as six of the seven subscales between this sample and that of Frostet al. No gender differences were found for any of the MPS scores. Internal reliability was found to be .88 for the total score, with subtests ranging from .57 to .95. Interscore correlations were relatively consistent with the Frostet al. sample except for a negative correlation between the PS subscale and the total score. There was a strong confirmation of the underlying factor structure reported by Frostet al. The overall impression was that the MPS is a psychometrically sound instrument of potential value in studying the construct of perfectionism.
