How impulsivity is related to intelligence and academic achievement

This study investigated the relationships between impulsivity, intelligence, and academic failure in a sample of 241 secondary school students who completed Thurstone's (1938) Primary Mental Abilities (PMA) test and Dickman's (1990) and Barratt's (1985) impulsivity questionnaires (DII and BIS-10, respectively). Results show an inverse relationship between impulsivity and intelligence, specific to the scales with higher loadings on crystallized intelligence, and a positive relationship between impulsivity and academic failure. These results indicate that impulsivity is not directly related to intelligence and may act as a moderator variable between individuals' resources and their achievements.     

The relationships between functional and dysfunctional impulsivity and aggression across different samples

E. S. Barratt proposed the term impulsive aggression to define a kind of aggression that is characterized by acting without thinking because of high levels of impulsivity. Previous research using psychometric measures has shown that impulsivity and aggression are related as far as psychometric measures are concerned. Nevertheless, most of the research has been done with samples of university students. Our research tests whether this relationship is stable across different samples; university students, teenagers and workers. Our results show that impulsivity and aggression have a consistent pattern of relationships across these samples, with impulsivity being specially related to emotional and instrumental aspects of aggression. Furthermore, the effects of anger on aggression seem to show a pattern of relationship that depends on age, with a tendency to physical aggression in young people and verbal aggression in adults.     

Psycholexical Value Factors in Spain and Their Relation with Personality Traits

The aim of the present study is to determine the structure of values in the Spanish population and its relation to the Big Five personality traits. Using a psycholexical approach, 566 words were identified as values and administered to a sample of participants who were instructed to rate the extent to which they were guided by each value. Principal components analysis revealed seven factors: Social Recognition, Competence, Love and Happiness, Benevolence, Idealism, Equilibrium and Family. The results show that there is no complete equivalence between these factors and those obtained in previous studies. However, the results are congruent with those obtained in other studies as far as the relation between values and personality traits is concerned. Copyright © 2011 John Wiley & Sons, Ltd.     

Baby talk from the perspective of discourse production: Linguistic choices and context coding by different speakers

Twenty men and 20 women with children under 3 years of age, and 20 men and 20 women without children were asked to select the most suitable utterance for a series of drawings representing different contexts of mother/father-infant interaction. Data were analyzed in three sections related to different hypotheses: In Phase 1, informational content and syntactic construction of sentences were selected in strict relationship with context by all speakers (closeness to context rule); in Phase 2, different speech acts were selected by different speakers within the same context (analysis of illocutionary force and canonicality); in Phase 3, the same contexts were linked to different interactional dimensions for the four groups, which formed different representations of the same interactional scene. Results are discussed in an attempt to integrate specific rules of adult-infant interaction and more general aspects of discourse production.     

Assessing extraversion and emotional stability in adolescents: development and validation of a questionnaire

A reduced version of the Five-factor Personality Inventory, which only considers two of the five original dimensions, was constructed to assess Extraversion and Emotional Stability especially for a sample of 581 adolescents. This used Items 6, 9, 11, 19, 21, 39, 41, 46, 54, 59, 61, 66, 84, 89, 91, and 99. Exploratory and confirmatory factor analysis showed that the factor structure of the questionnaire is acceptable, and both scales are reliable and correlated with similar measures as The Eysenck Personality Questionnaire-Revised.     

Functional and dysfunctional impulsivity in childhood and adolescence

There are few self-reports of impulsivity dealing with children, although this personality trait has been related to many behaviour problems in both children and adolescents. The appropriateness of the Dickman Impulsivity Inventory for Children (DII-c) and the Dickman Impulsivity Inventory (DII) to measure impulsivity in children and adolescents was assessed. The factorial structure of the DII-c and the internal consistencies for both inventories suggest the measured dimensions are not consistent until adulthood. These self-report measures are not appropriate for children and adolescents.
