Construct Validity of the Social Physique Anxiety Scale in a French Adolescent Sample

The present study explored the validity of constriction as an indicator of depression. Twenty-five patients displaying constriction in their Bender records and 25 patients not showing this indicator were compared with regard to MMPI Depression scores. A significant difference was found between D scores of these two groups (p<.05), supporting the validity of the indicator as an index of depression. Constriction was found to be infrequent, occurring in only 5.5% of the patient records. Although the indicator seems to be of some value as an indicator of depression its utility is lessened due its low rate of occurrence.     

Brief Sensation Seeking Scale for Chinese – Cultural adaptation and psychometric assessment

International behavioral research requires instruments that are not culturally-biased to assess sensation seeking. In this study we described a culturally adapted version of the Brief Sensation Seeking Scale for Chinese (BSSS-C) and its psychometric characteristics. The adapted scale was assessed using an adult sample (n = 238) with diverse educational and residential backgrounds. The BSSS-C (Cronbach alpha = 0.90) was correlated with the original Brief Sensation Seeking Scale (r = 0.85, p < 0.01) and fitted the four-factor model well (CFI = 0.98, SRMR = 0.03). The scale scores significantly predicted intention to and actual engagement in a number of health risk behaviors, including alcohol consumption, cigarette smoking, and sexual risk behaviors. In conclusion, the BSSS-C has adequate reliability and validity, supporting its utility in China and potential in other developing countries.     

Responsividad y condicionamiento semántico en relación con el ciclo menstrual

Resumen

El trabajo examina el efecto de cambios internos atribuibles al ciclo menstrual en la responsividad y condicionamiento psicofisiológico de un grupo de mujeres normales con ciclos naturales. Los sujetos fueron examinados Premenstrualmente (PM) o Intermenstrualmente (IM), utilizando como variables dependientes medidas psicofisiológicas (Conductancia de la Piel y Tasa Cardíaca) y cuestionarios. Los sujetos IM mostraron mayor responsividad y habituación en la actividad cardíaca y menores latencies de recuperación en la conductancia de la piel ante estimulación auditiva intensa, así como mayor condicionamiento en la conductancia de la piel (respuestas al segundo intervalo) que los sujetos PM. Las medidas actuales y retrospectivas de estados emocionales mostraron mayor afecto negativo (fatiga y tensión) en los sujetos PM y en l a fase premenstrual. Estos resultados son comparados con los de estudios similares realizados con pacientes fóbicas y son discutidos en términos de diferentes estados emocionales y de activación fisiológica asociados a las fases menstruales examinadas.     

La falacia de la validación personal: Más efectos placebo

RESUMEN

En este artículo se pone a prueba la influencia de efectos placebo en la aceptación de informes evaluativos y diagnósticos por los sujetos. Tras introducir brevemente el tema y plantear las hipótesis, los autores describen el método y los resultados de su investigación. En la discusión explican que estos resultados sugieren que la aceptación del diagnóstico que ofrece un profesional es un fenómeno general independiente de las características personales de los individuos que lo reciben, poniendo en entredicho el fenómeno de la validación personal y, al mismo tiempo, interactúa con determinadas características profesionales de los sujetos, ligadas a imágenes de personalidad a las que son más propensos. Los autores también analizan una limitación importante de su trabajo, el tamaño reducido de la muestra, y finalizan destacando que es el contenido del informe, más que el tipo de pruebas o profesionales, lo que parece afectar diferencialmente a distintos grupos profesionales.     

Person perception from changing emotional expressions: primacy,recency, or averaging effect?

ABSTRACT

Dynamic changes in emotional expressions are a valuable source of information in social interactions. As the expressive behaviour of a person changes, the inferences drawn from the behaviour may also change. Here, we test the possibility that dynamic changes in emotional expressions affect person perception in terms of stable trait attributions. Across three experiments, we examined perceivers’ inferences about others’ personality traits from changing emotional expressions. Expressions changed from one emotion (“start emotion”) to another emotion (“end emotion”), allowing us to disentangle potential primacy, recency, and averaging effects. Drawing on three influential models of person perception, we examined perceptions of dominance and affiliation (Experiment 1a), competence and warmth (Experiment 1b), and dominance and trustworthiness (Experiment 2). A strong recency effect was consistently found across all trait judgments, that is, the end emotion of dynamic expressions had a strong impact on trait ratings. Evidence for a primacy effect was also observed (i.e. the information of start emotions was integrated), but less pronounced, and only for trait ratings relating to affiliation, warmth, and trustworthiness. Taken together, these findings suggest that, when making trait judgements about others, observers weigh the most recently displayed emotion in dynamic expressions more heavily than the preceding emotion.     

ON PARADIGM SHIFT IN READING/LITERACY RESEARCH

Abstract

Research is just a set of conventions‐‐the most rigorous way to ask a question and look for answers...research is people-run. And it can be as flexible as the people who run it (Hatch & Farhady, 1982, p. xv).     

The Eating Attitudes Test-26 Revisited using Exploratory Structural Equation Modeling

Most previous studies have failed to replicate the original factor structure of the 26-item version of the Eating Attitudes Test (EAT-26) among community samples of adolescents. The main objective of the present series of four studies (n?=?2178) was to revisit the factor structure of this instrument among mixed gender community samples of adolescents using both exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA). First, results from the ESEM analyses provided satisfactory goodness-of-fit statistics and reliability coefficients for a six-factor model of the EAT with 18 items (EAT-18) closely corresponding to the original seven-factor structure proposed for the 40-item version of the EAT. Second, these analyses were satisfactorily replicated among a new sample of community adolescents using CFA. The results confirmed the factor loading and intercept invariance of this model across gender and age groups (i.e., early and late adolescence), as well as the complete invariance of the EAT-18 measurement model between ethnicities (i.e., European versus African origins) and across weight categories (i.e., underweight, normal weight and overweight). Finally, the last study provided support for convergent validity of the EAT-18 with the Eating Disorder Inventory and with instruments measuring global self-esteem, physical appearance, social physique anxiety and fear of negative appearance evaluation.     

Growth orientation of one-dimensional silicon nanowires prepared by thermal evaporation

One-dimensional silicon nanowires have been grown by thermal evaporation and their growth orientations determined by transmission electron microscopy studies. The nanowires, which are often highly curved in morphology and heavily twinned in microstructure, are crystallographically separated into several sections, each with a characteristic crystallographic orientation along the wire axis. Straight nanowires, or straight sections in a curved nanowire, are found to have non-unique crystallographic orientations when {111} twinning occurs.     

Need for closure and heuristic information processing: The moderating role of the ability to achieve the need for closure

In contrast to the ample research that shows a positive relationship between the need for closure (NFC) and heuristic information processing, this research examines the hypothesis that this relationship is moderated by the ability to achieve closure (AAC), that is, the ability to use information‐processing strategies consistent with the level of NFC. Three different operationalizations of heuristic information processing were used: recall of information consistent with the impression (Study 1); pre‐decisional information search (Study 2); and stereotypic impression formation (Study 3). The results of the studies showed that there were positive relationships between NFC and heuristic information processing when participants assessed themselves as being able to use cognitive strategies consistent with their level of NFC (high AAC). For individuals with low AAC, the relationships were negative. Our data show that motivation–cognition interactions influence the information‐processing style.     

The cognitive advantage for one’s own name is not simply familiarity: An eye-tracking study

Eye-tracking technique and visual search task were employed to examine the cognitive advantage for one’s own name and the possible effect of familiarity on this advantage. The results showed that fewer saccades and an earlier start time of first fixations on the target were associated with trials in which participants were asked to search for their own name, as compared to search for personally familiar or famous names. In addition, the results also demonstrated faster response times and higher accuracy in the former kind of trials. Taken together, these findings provide important evidence that one’s own name has the potential to capture attention and that familiarity cannot account for this advantage.
