Effects of an intervention in active strategies for text comprehension and recall

The aim of this study was to investigate the effects of an intervention program to promote active text-processing strategies (main-idea identification and summarization) at two developmental levels (12- and 16-year-olds). The independent variables were training condition (experimental and control) and school level (7th and 10th grades). Several measures were taken as dependent variables: reading span, reading time, construction of macrostructure, and structural recall. The hypothesis claimed that training would increase comprehension and recall significantly. Furthermore, as a result of the training program, a reduction in developmental differences in the experimental groups at posttest was also expected. Results supported the predictions, showing a significant improvement in the experimental groups' reading comprehension and recall. These results are discussed in terms of the importance of active and self-controlled strategies for text comprehension and recall.     

Null sex differences in general intelligence: evidence from the WAIS-III

There is an increasing number of studies claiming that the sex differences in general intelligence are "real." The empirical evidence is based on the summation of the standardized sex differences in several cognitive batteries. However, the scientific construct of general ability rests on the correlations among test scores, rather than on their summation. The latter (ability in general) is an arbitrary variable, not a scientific construct. General ability is not a function of any particular cognitive test, but a source of variance evidenced by the correlation between several diverse tests, each of which reflects general ability (g) to some extent, but also group factors and test specificity. Because there are important educational, economic, and social consequences of a group difference in general ability, it is especially germane to evaluate the possibility of an average sex difference in its proxy measures, such as IQ. The Spanish standardization of the WAIS-III is analyzed in the present study. The sample was made up of 703 females and 666 males, aged 15-94, drawn as a representative sample of the population in terms of educational level and geographical location. Although a male advantage of 3.6 IQ points is observed, the difference is in "ability in general," not in "general ability" (g). Given that the main ingredient of the strong association between IQ and a broad range of social correlates is g, and given that there is no sex difference in g, then the average IQ sex-difference favoring males must be attributed to specific group factors and test specificity.     

Modification of coronary-prone behaviors in coronary patients of low socio-economic status

The purpose of this study is to determine the effectiveness of a group cognitive-behavioral treatment to modify coronary-prone behaviors in patients from a fairly low social and educational level. Participants were 98 male coronary patients randomly allocated to one experimental and two control groups. All groups received standard medical treatment. The experimental group received an additional psychological treatment and one of the two control groups received a health education treatment. Results showed that only the psychological treatment group significantly reduced Pressured Drive and Speed-Impatience after treatment, and at 1- and 2-year follow-ups. Depression was also significantly reduced only in this group at 2-year follow-up. The results are considered a reliable first step in the process of validating this program designed to improve coronary heart disease patients' quality of life.     

Temporal performance in 4-8 year old children. The effect of chronometric information in task execution

The present study explores temporal performance in children between 4 and 11 years of age. In order to optimise the children's performance, verbal instructions and demonstrations were used to specify the temporal requirement of the task. Moreover, specific feedback was given, which indicated the success of a response, or, in case of a mistake, indicated the type of error made. The task was presented in two phases: training and experimental. In the first phase, the child practised until a learning criterion was reached. In the experimental phase, four conditions were defined according to the information provided to the children. In general, the results of the training phase showed an improvement in performance with advancing age. Significant differences were found in children between 7 and 8 years of age, which points to an important transition period. Results of the experimental phase showed a pronounced impact of instructions on the performance of the task and on the strategies used to control timing behaviour. Specifically, the instructions that contained chronometric information caused an impairment in task performance and a change in the strategy used.     

HDC: A subroutine library for image processing using Burt’s hierarchical discrete correlation

This paper describes a library of subroutines that efficiently implement Burt’s (1981) hierarchical discrete correlation (HDC). The subroutines are written in Professional FORTRAN for IBM PCs or compatibles. Subroutines are included for both even and odd forms of the HDC, as well as for the corresponding algorithms for pyramid processing. Odd width kernels of up to 7×7 pixels and even width kernels of up to 6×8 pixels can be programmed easily with these subroutines. Thus, this library contains the forms of HDC that are most widely used in image processing and visual modeling. I show the efficiency of this implementation by reporting the execution time of each subroutine for several image sizes. I also present a method that simulates rotation of the kernel in order to allow applying kernels without circular symmetry at the desired orientation.     

Identifying the Null Subject: Evidence from Event-Related Brain Potentials

Event-related brain potentials (ERPs) were recorded during spoken language comprehension to study the on-line effects of gender agreement violations in controlled infinitival complements. Spanish sentences were constructed in which the complement clause contained a predicate adjective marked for syntactic gender. By manipulating the gender of the antecedent (i.e., the controller) of the implicit subject while holding constant the gender of the adjective, pairs of grammatical and ungrammatical sentences were created. The detection of such a gender agreement violation would indicate that the parser had established the coreference relation between the null subject and its antecedent. The results showed a complex biphasic ERP (i.e., an early negativity with prominence at anterior and central sites, followed by a centroparietal positivity) in the violating condition as compared to the non-violating conditions. The brain reacts to NP-adjective gender agreement violations within a few hundred milliseconds of their occurrence. The data imply that the parser has properly coindexed the null subject of an infinitive clause with its antecedent.     

THE DUAL-FOCUS APPROACH TO CREATING BILINGUAL MEASURES

The dual-focus approach to creating bilingual research protocols requires a bilingual/bicultural research team, including indigenous researchers from the cultures being studied. The presence of indigenous researchers as full and equal members of the research team can guard against an unexamined exportation of ideas and methods developed in one culture to other cultural/linguistic communities. The team develops the research plan and a research protocol that express a given concept with equal clarity, affect, and level of usage simultaneously in two languages. The dual-focus method employs a concept-driven rather than a translation-driven approach to attain conceptual and linguistic equivalence. Examples of the application of this approach to creating new measures in Spanish and English, adapting existing measures, revising instructions to research participants, and correcting official translations are provided.     

Satisfaction with life scale: analysis of factorial invariance for adolescents and elderly persons

The purpose of this work is to analyze the factorial invariance of the Satisfaction With Life Scale across samples of adolescents and elderly persons. Data from 266 subjects were analyzed. Half were Spanish junior high-school students (65 girls and 68 boys) and the other half were Spanish elderly people (68 women and 65 men). Single-group analyses showed an acceptable one-factor model for both adolescent and elderly groups. Sequential multigroup analyses to test the equivalence of factor structures for adolescent and elderly groups showed that factor loadings and variances are not invariant. The scale is sensitive to age in these groups.     

Are emotionally intelligent people less prejudiced? The importance of emotion management skills for outgroup attitudes

People vary in their ability to understand, process, and manage information about one's own and others’ emotions, a construct known as Emotional Intelligence (EI). Past research highlighted the importance of EI in interpersonal relations as well as the key role of emotions underlying outgroup prejudice. Remarkably, hardly any research has investigated the associations between EI and outgroup prejudice. In three studies (total N = 922) conducted in Spain and the United Kingdom, we measured emotional intelligence using self-report and performance tests and prejudice toward a variety of outgroups. Results showed that those with stronger performance-based emotion management skills expressed lower generalized ethnic prejudice (Studies 1–3), more positive attitudes toward immigrants (Study 2a) and refugees (Study 2b), and less homophobic attitudes (Study 3). This negative association between emotion management and prejudice was found with different performance-based EI measures and held after controlling for self-perceived EI (Study 1) and self-reported abilities to regulate emotions (Study 3). Study 3 further demonstrated that higher empathy partly accounted for the association between emotion management and prejudice. The findings suggest that emotion management abilities play an important, but so far largely neglected role in generalized prejudice.
