Salivary testosterone is related to both handedness and degree of linguistic lateralization in normal women.
2003
The aim of this study was to test the hypothesis that individual differences in testosterone (T) are associated with different patterns of linguistic lateralization and hand preference. Twenty left-handed (LH) and 19 right-handed (RH) women filled in a handedness questionnaire and performed a consonant–vowel dichotic listening test (DL-CV). Salivary T was measured by radioimmunoassay (RIA). LH women showed significantly lower mean salivary T than RH women. T levels were negatively correlated with the absolute value of the DL laterality index. Subjects with right ear advantage (REA) were classified into strongly and weakly lateralized following Wexler et al. method (Brain Lang. 13 (1981) 13)…
Hormonal Alterations in Victimized Women Explained by Their Hostile Reactions in Coping with Couple Violence
2019
AbstractRecent studies have highlighted the dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity and its end products, cortisol and dehydroepiandrosterone (DHEA), in women with a history of intimate partner violence (IPV) victimization. These studies analyzed several coping styles, but they neglected to examine the use of violent strategies to confront IPV and the way these strategies affect HPA functioning. This latter proposal would be based on the gender symmetry model of IPV, which sustains that IPV is generally symmetrical, but that women’s violence tends to be a reaction to male violence. Hence, the main objective of the present study was to examine whether women’s viol…
A Comparative Study of General Intelligence in Spanish and Moroccan Samples
2012
The aim of this study is to fill a gap in intelligence research by presenting data for the average IQ in Morocco and for a comparable sample in Spain. Adult samples were administered theRaven Standard Progressive Matrices (SPM)(Raven, Court, & Raven, 2001) and scored for the total test and for the three sub-factors of gestalt continuation, verbal-analytical reasoning and visuospatial ability identified by Lynn, Allik, and Irwing (2004). The total test and the three factors have shown satisfactory reliability. Our results for the Moroccan sample show significant relationship between general intelligence factor, gestalt continuation and visuospatial ability with education level and income…
The external frame function in the control of pitch, register, and singing mode: Radiographic observations of a female singer
1999
Summary This study investigates pitch control, register, and singing mode related movements of the laryngo-pharyngeal structures by radiographic methods. One trained female singer served as the subject. The results show that singing voice production involves complex movements in the laryngeal structures. Pitch related increase in the thyro-arytenoid distance (vocal fold length) is nonlinear, slowing down as pitch rises. Similar observations have been made earlier. At the highest pitches, a shortening of the distance can be seen, suggesting the use of alternative pitch control mechanisms. The various observations made support the existence of three registers in this trained female singing vo…
Conditional reasoning by mental models: chronometric and developmental evidence
2000
The aim of this article is to verify two predictions resulting from the mental models theory of conditional reasoning. First, the denial of antecedent (DA) and modus tollens (MT) inferences should take longer to verify than modus ponens (MP) and affirmation of consequent (AC) because the former require subjects to flesh out the initial model whereas the latter do not. This prediction was confirmed in two reaction time experiments in adults. In line with Evans' proposal (Evans, J. St. B. T. (1993). The mental model theory of conditional reasoning: critical appraisal and revision. Cognition, 48, 1-20), there was a strong directionality effect: inferences from antecedent to consequent (MP and …
Multilevel Models in the Explanation of the Relationship between Safety Climate and Safe Behavior
2013
AbstractThis study examines the relationships between components of organizational safety climate, including employee attitudes to organizational safety issues; perceptions of the physical working environment, and evaluations of worker engagement with safety issues; and relates these to self-reported levels of safety behavior. It attempts to explore the relationships between these variables in 1189 workers across 78 work groups in a large transportation organization. Evaluations of safety climate, the working environment and worker engagement, as well as safe behaviors, were collected using a self report questionnaire. The multilevel analysis showed that both levels of evaluation (the work …
When nominal features are marked on verbs: A transcranial magnetic stimulation study
2006
It has been claimed that verb processing (as opposed to noun processing) is subserved by specific neural circuits in the left prefrontal cortex. In this study, we took advantage of the unusual grammatical characteristics of clitic pronouns in Italian (e.g., lo and la in portalo and portala 'bring it [masculine]/[feminine]', respectively)-the fact that clitics have both nominal and verbal characteristics, to explore the neural correlates of verb and clitic processing. We used repetitive transcranial magnetic stimulation (rTMS) to suppress the excitability of the left prefrontal cortex and to assess its role in producing verb+det+noun and verb+clitic phrases. Results showed an interference ef…
On methods of access to the structure of social representations: the example of Europe.
2012
espanolEl objetivo de este estudio es identificar la logica detras de una serie de metodos estadisticos utilizados para revelar la estructura de las representaciones sociales. Se solicito a un numero de sujetos (n = 317) responder a la pregunta siguiente: �Para cada categoria de europeo, por favor indique con que otros europeos le gustaria tener contacto�. Los resultados de los analisis de similitud nos llevan a la conclusion de que existe un sesgo etnocentrico, y revelan el factor central de la representacion. La representacion obtenida por el analisis factorial de correspondencias se parece mas a la realidad actual y nos permite entender las divisiones que han estructurado Europa y perman…
Measures of native and non-native rhythm in a quantity language.
2005
The traditional phonetic classification of language rhythm as stress-timed or syllable-timed is attributed to Pike. Recently, two different proposals have been offered for describing the rhythmic structure of languages from acoustic-phonetic measurements. Ramus has suggested a metric based on the proportion of vocalic intervals and the variability ( SD) of consonantal intervals. Grabe has proposed Pairwise Variability Indices (nPVI, rPVI) calculated from the differences in vocalic and consonantal durations between successive syllables. We have calculated both the Ramus and Grabe metrics for Latvian, traditionally considered a syllable rhythm language, and for Latvian as spoken by Russian l…
From the Big Five to the General Factor of Personality: a Dynamic Approach
2014
AbstractAn integrating and dynamic model of personality that allows predicting the response of the basic factors of personality, such as the Big Five Factors (B5F) or the general factor of personality (GFP) to acute doses of drug is presented in this paper. Personality has a dynamic nature, i.e., as a consequence of a stimulus, the GFP dynamics as well as each one of the B5F of personality dynamics can be explained by the same model (a system of three coupled differential equations). From this invariance hypothesis, a partial differential equation, whose solution relates the GFP with each one of the B5F, is deduced. From this dynamic approach, a co-evolution of the GFP and each one of the B…
