Contrastación de teorías de representación y razonamiento sobre silogismos lineales

Resumen

El objetivo de esta investigación es la comprobación de la capacidad predictiva de los distintos modelos existentes sobre razonamiento y representación en silogismos lineales: modelo de la imagen, lingüístico-proposicional, mixto y de niveles de representación. Se utilizaron 64 tipos de silogismos lineales con el fin de cumplir los requisitos mínimos necesarios para utilizar la metodología empleada. Aunque los resultados obtenidos no presentan diferencias estadísticamente significativas entre los dos modelos con mayor capacidad predictiva, el modelo de niveles de representación supera al modelo mixto.     

Desarrollo cognitivo y comunicación intencional preverbal: un estudio longitudinal multivariado

Resumen

A partir de la revisión de las investigaciones sobre las relaciones entre la aparición de la intención comunicativa y el desarrollo sensoriomotor, se planteó la conveniencia de realizar un estudio empírico que permitiera profundizar en el estudio de estas relaciones desde una perspectiva de análisis multivariado. Para ello se realizó un estudio longitudinal de 16 sujetos, con tres momentos de medida (en torno a los ocho, diez y doce meses de edad). Los sujetos fueron evaluados mediante la aplicación de las escalas Uzgiris y Hunt (1975) y grabados en dos situaciones de interacción diàdica, una libre con su madre y otra semiestructurada de carácter elicitador. La conducta comunicativa de los niños fue registrada mediante un sistema de codificación diseñado con tal fin (Sarriá, 1991). Los datos fueron analizados mediante análisis de correlaciones y análisis de correspondencias múltiples. Los resultados obtenidos no apoyan la hipótesis de la homología local sobre la interdependencia de determinadas capacidades cognitivas y el desarrollo comunicativo planteada por Bates, Benigni, Bretherton, Camaioni y Volterra (1979), sino más bien sugieren una hipótesis de diferenciación entre los dominios de adaptación al mundo físico y el social-comunicativo, en el período de aparición de la intención comunicativa.     

Neuropsychological Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) Assessment: A Shortened Sensitivity to Punishment and Sensitivity to Reward Questionnaire Version (SPSRQ–20)

This research was designed to investigate the items and factor structure of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) proposed by Torrubia, Avila, Moltó, and Caseras (2001 Spielberger, C. D., Gorsuch, R. L. and Lushene, R. E. 1970. Manual for the State-Trait Anxiety Inventory., Palo Alto, CA: Consulting Psychologists Press.  [Google Scholar]), as a measure of the behavioral inhibition system and behavioral activation system in Gray's reinforcement sensitivity theory. Recent studies that analyzed this instrument by exploratory and confirmatory factor analysis suggest the need for structural refinement. The Spanish version of the SPSRQ was analyzed by exploratory and confirmatory procedures in calibration (n = 2,102) and validation (n = 746) independent samples. In addition, convergent and discriminant validity was evaluated with the Zuckerman–Kuhlman Personality Questionnaire (Zuckerman, Kuhlman, Teta, Joireman, &; Kraft, 1993 Torrubia, R. and Tobeña, A. 1984. A scale for the assessment of susceptibility to punishment as a measure of anxiety: Preliminary results. Personality and Individual Differences, 5: 371–375. [Crossref], [Web of Science ®] , [Google Scholar]), the Impulsiveness, Venturesomeness and Empathy Inventory (S. B. G. Eysenck, Pearson, Easting, &; Allsopp, 1985 Eysenck, S. B. G., Pearson, P. R., Easting, G. and Allsopp, F. J. 1985. Age norms for impulsiveness, venturesomeness and empathy in adults. Personality and Individual Differences, 6: 613–619. [Crossref], [Web of Science ®] , [Google Scholar]) the Neuroticism, Extraversion and Openness Five Factor Inventory (Costa &; McCrae, 1992 Costa, P. T. and McCrae, R. R. 1992. NEO–PI–R professional manual: Revised NEO Personality Inventory (NEO–PI–R) and NEO Five Factor Inventory (NEO–FFI), Odessa, FL: Psychological Assessment Resources.  [Google Scholar]), and the Barratt Impulsiveness Scales (Barratt, 1985 Ball, S. and Zuckerman, M. 1990. Sensation seeking, Eysenck's personality dimensions and reinforcement sensitivity in concept formation. Personality and Individual Differences, 11: 343–355. [Crossref], [Web of Science ®] , [Google Scholar]). Results showed the robustness of a 20-item structure of the SPSRQ, with satisfactory fit adjustment, validity, and reliability. The findings are discussed in terms of the better functioning and sound psychometric properties of the SPSRQ 20-item version for Gray's personality theory.     

On Gentzen Relations Associated with Finite-valued Logics Preserving Degrees of Truth

When considering m-sequents, it is always possible to obtain an m-sequent calculus VL for every m-valued logic (defined from an arbitrary finite algebra L of cardinality m) following for instance the works of the Vienna Group for Multiple-valued Logics. The Gentzen relations associated with the calculi VL are always finitely equivalential but might not be algebraizable. In this paper we associate an algebraizable 2-Gentzen relation with every sequent calculus VL in a uniform way, provided the original algebra L has a reduct that is a distributive lattice or a pseudocomplemented distributive lattice. We also show that the sentential logic naturally associated with the provable sequents of this algebraizable Gentzen relation is the logic that preserves degrees of truth with respect to the original algebra (in contrast with the more common logic that merely preserves truth). Finally, for some particular logics we obtain 2-sequent calculi that axiomatize the algebraizable Gentzen relations obtained so far.     

Clinical Utility of the Bem Sex Role Inventory (BSRI) in the Spanish Transsexual and Nontranssexual Population

The aim of the study is to evaluate the usefulness of the Bem Sex Role Inventory (BSRI; Bem, 1974), an overall measurement of the cultural construct of masculinity and femininity, in the psychological assessment of Spanish transsexuals. Seventy male-to-female transsexuals (MF), 51 female-to-male transsexuals (FM), 77 control men, and 79 control women completed the Spanish version of the BSRI. Statistically significant differences between groups were only found on the femininity scale, on which MF transsexuals and control women scored significantly higher than FM transsexuals and control men. The results indicate that (a) only the femininity scale of the BSRI appears to be useful today for evaluating differences in the sex-role identification in Spanish controls and transsexuals; and (b) MF and FM transsexuals score as a function of their gender identity instead of their anatomical sex on the BSRI femininity scale.     

Both associative activation and thematic extraction count,but thematic false memories are more easily rejected

The main aim of this study was to analyse the roles played by associative activation and thematic extraction in the explanation of false memories using the Deese, Roediger, McDermott (DRM) paradigm. Associative lists with two different types of critical items (CIs) were used: one, the associative CI, corresponded to the word most strongly primed by the associates in the list and another, the thematic CI, was the word that best described the theme of the list. Following three different types of encoding instructions (standard, warning or strategic), false recognition for these two types of CIs was analysed in either self-paced or speeded response recognition tests. The results showed considerable levels of false memories for both types of CIs. Even without the quality of being “good themes”, associative CIs produced high levels of false recognition, which suggests that associative activation plays a prominent role in false memory formation. More interestingly, thematic CIs were more prone to be edited out, reinforcing the argument that thematic identifiability has a major role in the rejection of false memories.     

The Little Six Personality Dimensions From Early Childhood to Early Adulthood: Mean‐Level Age and Gender Differences in Parents' Reports

The present research pursues three major goals. First, we develop scales to measure the Little Six youth personality dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience, and Activity. Second, we examine mean‐level age and gender differences in the Little Six from early childhood into early adulthood. Third, we examine the development of more specific nuance traits. We analyze parent reports, made using the common‐language California Child Q‐Set (CCQ), for a cross‐sectional sample of 16,000 target children ranging from 3 to 20 years old. We construct CCQ–Little Six scales that reliably measure each Little Six dimension. Using these scales, we find (a) curvilinear, U‐shaped age trends for Agreeableness, Conscientiousness, and Openness, with declines followed by subsequent inclines; (b) monotonic, negative age trends for Extraversion and Activity; (c) higher levels of Conscientiousness and Agreeableness among girls than boys, as well as higher levels of Activity among boys than girls; and (d) gender‐specific age trends for Neuroticism, with girls scoring higher than boys by mid‐adolescence. Finally, we find that several nuance traits show distinctive developmental trends that differ from their superordinate Little Six dimension. These results highlight childhood and adolescence as key periods of personality development.     

The five and seven factors personality models: differences and similitude between the TCI-R, NEO-FFI-R and ZKPQ-50-CC

The present study tests the relationships between the three frequently used personality models evaluated by the Temperament Character Inventory-Revised (TCI-R), Neuroticism Extraversion Openness Five Factor Inventory - Revised (NEO-FFI-R) and Zuckerman-Kuhlman Personality Questionnaire-50- Cross-Cultural (ZKPQ-50-CC). The results were obtained with a sample of 928 volunteer subjects from the general population aged between 17 and 28 years old. Frequency distributions and alpha reliabilities with the three instruments were acceptable. Correlational and factorial analyses showed that several scales in the three instruments share an appreciable amount of common variance. Five factors emerged from principal components analysis. The first factor was integrated by A (Agreeableness), Co (Cooperativeness) and Agg-Host (Aggressiveness-Hostility), with secondary loadings in C (Conscientiousness) and SD (Self-directiveness) from other factors. The second factor was composed by N (Neuroticism), N-Anx (Neuroticism-Anxiety), HA (Harm Avoidance) and SD (Self-directiveness). The third factor was integrated by Sy (Sociability), E (Extraversion), RD (Reward Dependence), ImpSS (Impulsive Sensation Seeking) and NS (novelty Seeking). The fourth factor was integrated by Ps (Persistence), Act (Activity), and C, whereas the fifth and last factor was composed by O (Openness) and ST (Self- Transcendence). Confirmatory factor analyses indicate that the scales in each model are highly interrelated and define the specified latent dimension well. Similarities and differences between these three instruments are further discussed.     

Personality and job stress: a comparison of direct effects on parenting

The impact of personality and job characteristics on parental rearing styles was compared in 353 employees. Hypotheses concerning the relationships between personality and job variables were formulated in accordance with findings in past research and the Belsky's model (1984). Structural equation nested models showed that Aggression-hostility, Sociability and job Demand were predictive of Rejection and Emotional Warmth parenting styles, providing support for some of the hypothesized relationships. The findings suggest a well-balanced association of personality variables with both parenting styles: Aggression-Hostility was positively related to Rejection and negatively to Emotional Warmth, whereas Sociability was positively related to Emotional Warmth and negatively related to Rejection. Personality dimensions explained a higher amount of variance in observed parenting styles. However, a model that considered both, personality and job dimensions as antecedent variables of parenting was the best representation of observed data, as both systems play a role in the prediction of parenting behavior.
