Retrieval-induced forgetting in perceptually driven memory tests

Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate transfer between representations and competition rather than on the nature of the final test. The authors adapted the standard paradigm to introduce lexical categories (words that shared the first 2 letters) at study and practice. Direct and indirect fragment completion tests were used at retrieval. The results showed significant RIF effects in perceptually driven tasks. Furthermore, they indicated that the presence of RIF effects depended on using adequate cuing to induce competition during the retrieval practice and on the final memory test tapping the inhibited representation.     

Serial dependence in the estimation of a car's arrival time

Serial dependence of a car's arrival time. We have studied the sequential structure of data in the arrival- time estimations. Forty participants estimated the arrival-time of a vehicle under two experimental conditions: real car and video-image. Various time series regression models were fit to our data, and residuals autocorrelations were computed. For each serial-dependence model, data were fit to three functions, namely, power, logarithmic, and linear. In both experimental conditions, the response magnitude (R) on a given trial in t was a function of the stimulus intensity (S) in such a trial (t) and of the S and R on t-1 and t-2. Assimilation effect to the previous responses and contrast effect to the previous stimuli has been found.     

Irritation: analysis of an instrument to assess stress at work

The aim of this investigation is to verify the factorial validity of the "Scale Irritation" in a sample of 181 teachers of Secondary Education from the center of Spain. At the same time, the investigation tries to verify the validity of construct of the scale correlating the results with the burnout evaluated through the Brief Questionnaire of Burnout adapted for teachers. The results obtained by means of the exploratory factor analysis of the Scale Irritation confirm the presence of two factors, as it appears in other international investigations. The confirmatory analysis verifies the proposal of a model of two factors. The significant correlation obtained among the Irritation Scale and the burnout confirms the validity of construct and verifies that a high irritation is associated significantly to the burnout, as it is foreseen by the theory, which considers both aspects related to the process of stress at work.     

Comparing speed estimations from a moving vehicle in different traffic scenarios: absence versus presence of traffic flow

The aim of this research was to study the performance in a speed estimation task of a passenger travelling in a real car in different scenarios: a closed track used in previous experimental studies was compared with interurban traffic environment involving a secondary road and a highway. At the same time, the effect of sex and driving experience on speed estimation was analyzed. Thirty-six participants (18 male and 18 female, half of each group being drivers and half non-drivers) estimated the speed of the car in which they travelled as passengers. The actual speed values varied in the range of 40-100 km/h for the secondary road, 70-120 km/h for the highway condition, and 40-120 km/h for the track. The results obtained for the track in previous studies (Recarte and Nunes, 1996; Recarte, Conchillo, and Nunes, 2004, 2005) were replicated in the same condition and were also verified for the secondary road scenario. However, a different pattern of errors was found for the highway. From the viewpoint of psychophysics, the participants were more accurate on the without-traffic track than in real traffic conditions, considered as a whole. The differences found between road and highway are discussed. No effect was found for between- subject variables, sex, and driving experience.     

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.     

Effect of a simple experimental control: The recall constraint in Sternberg's memory scanning task

This study was aimed at determining how a simple experimental control—recalling the sequence of digits in the order they were presented—may affect quantitative and qualitative performance in Sternberg's short-term memory scanning paradigm. First, the presence or absence of this constraint was shown to have practically no effect on the relationship between sequence length and mean response time: the two general laws proposed by Sternberg were found to hold true in both experimental conditions. However, subjects who had to recall the digit sequence were consistently slower than those who did not, and the yes response curves of the two experimental conditions differed in shape. Moreover, correlations between parameters of the linear function and various aptitude scores showed that this task was linked to the memory span only when the participants had to recall the digit sequence. If our results are confirmed, they should help to improve the interpretation of the data collected in many studies that use this paradigm in cognitive psychology as well as in neuroscience of memory.
