Full naming with bi-dimensional abstract stimuli in six-year-old children

The aim of this study was to evaluate a procedure to reveal the emergence of full naming in typically developing children. In Experiment 1, five 6-year-old children (a) learned tacts of pictures and the emergence of the selection of these pictures upon hearing their names was tested; and (b) the selection of other pictures was taught and the emergence of the tacts was tested. All children showed the emergence of picture selection and 3 children showed the emergence of the tacts. In Experiment 2a, the children's correct repetition of the names of 3 pictures was verified first, then the experimenter presented the pictures with their names without requiring any behavior other than attending. Finally, the emergence of picture selection and the tacts was tested. Experiment 2b replicated Experiment 2a with words that were easier to pronounce. Picture selection and the tacts emerged; this performance documented full naming for the first time with typically developing children. These procedures can be used to induce naming capacity in children who lack it; hence, they can be applied to teach children with learning delays.     

Psychological variables in the control of brain-computer interfaces

BCI (Brain-Computer Interface) is a system that allows interaction between the human brain and a computer. It is based on analyzing electroencephalographic signals (EEG) and processing them to generate control commands. The study analyzed the possible influence of psychological variables, such as the imaginative kinesthetic capacity and anxiety, in relation to performance in a BCI. All participants (4 male and 19 female students) completed the questionnaires and carried out a session of BCI to control their EEG signals in a virtual setting of a car along a straight road. The group was divided into two subgroups according to their EEG signals or differential responses obtained in the left-right discrimination. Study results showed no significant differences in cognitive variables of imagination or in anxiety. By comparing the degree of participants' BCI control, a new quantitative parameter for comparing performances and making decisions in signal processing was found. The findings, the ongoing research process to refine the control of a BCI, and the interaction of psychological and computer procedures are discussed.     

Development and validation of a Spanish version of the Athletic Coping Skills Inventory, ACSI-28

This study involved the translation, cultural adaptation and validation of the Athletic Coping Skills Inventory (ACSI-28) for a Spanish-speaking sport environment. The sample was made up of 1,253 Spanish athletes, 967 males and 286 females. Confirmatory factor analysis (CFA) showed that the 7-factor structure found in the English version was replicated in the Spanish translation in both males and females. Likewise, the reliability coefficients were similar to those of the English version, with values exceeding .80 for the total score. Several of the subscales correlated positively with sports experience and performance level. The Spanish version of the ACSI-28 thus maintains the factor structure of the original and exhibits similar psychometric properties. Consequently, it can reliably be applied to Spanish-speaking athletes for research and evaluation purposes.     

Internal attribution of outcome moderates the cortisol response to a cooperative task in women

Several ethological reports have indicated that cooperative behaviors play an adaptive role. However, research has focused on competition in men, and there have been few studies on cooperation. This study aims to analyze the cortisol and psychological responses in women to a cooperative situation compared with a competitive situation in a laboratory context. The sample was distributed into four groups depending on the task and the outcome obtained: Positive cooperation, negative cooperation, competition with victory, and competition with defeat. Our results show that, in comparison with competition, cooperation produces different effects in cortisol, but not in psychological states. Nevertheless, these effects occur only when the task outcome and its appraisal are considered. Only the participants who cooperated and obtained a positive outcome and those who competed and lost showed significant decrements of cortisol. Internal attribution was higher in groups with more stable cortisol levels, suggesting a possible modulator effect of controllability in the way the situation was experienced. These results could be generalized to situations in which negotiation, mediation, and cooperative strategies are relevant for making decisions and/or solving problems.     

Associations between parental educational/occupational levels and cognitive performance in Spanish adolescents: the AVENA study

We examined the associations between parental educational/occupational levels and cognitive performance in Spanish adolescents. Cognitive performance was measured by a validated Scholar Aptitudes test in 2,162 participants. Parental educational and occupational levels were positively associated with all specific cognitive abilities and the overall score (p<001 to .04). The odds ratios of having a high cognitive performance (top quartile) in adolescents with high parental educational level were 1.6 to 1.7 times higher than for those with a low parental educational level. Similarly, the odds ratios were 1.9 to 2.4 times higher for adolescents with high parental occupational level. These findings suggest an association between parental educational/occupational levels and cognitive performance in Spanish adolescents and support the parents' role in the creation of a stimulating intellectual environment.     

Exposure to severe urban air pollution influences cognitive outcomes, brain volume and systemic inflammation in clinically healthy children

Exposure to severe air pollution produces neuroinflammation and structural brain alterations in children. We tested whether patterns of brain growth, cognitive deficits and white matter hyperintensities (WMH) are associated with exposures to severe air pollution. Baseline and 1 year follow-up measurements of global and regional brain MRI volumes, cognitive abilities (Wechsler Intelligence Scale for Children-Revised, WISC-R), and serum inflammatory mediators were collected in 20 Mexico City (MC) children (10 with white matter hyperintensities, WMH⁺, and 10 without, WMH⁻) and 10 matched controls (CTL) from a low polluted city. There were significant differences in white matter volumes between CTL and MC children - both WMH⁺ and WMH⁻ - in right parietal and bilateral temporal areas. Both WMH⁻ and WMH⁺ MC children showed progressive deficits, compared to CTL children, on the WISC-R Vocabulary and Digit Span subtests. The cognitive deficits in highly exposed children match the localization of the volumetric differences detected over the 1 year follow-up, since the deficits observed are consistent with impairment of parietal and temporal lobe functions. Regardless of the presence of prefrontal WMH, Mexico City children performed more poorly across a variety of cognitive tests, compared to CTL children, thus WMH⁺ is likely only partially identifying underlying white matter pathology. Together these findings reveal that exposure to air pollution may perturb the trajectory of cerebral development and result in cognitive deficits during childhood.     

Evaluation of Affect in Mexico and Spain: Psychometric Properties and Usefulness of an Abbreviated Version of the Day Reconstruction Method

The aims of the present study were to assess the psychometric properties of the Spanish-language version of the abbreviated Day Reconstruction Method (DRM), and to investigate differences in affective experience in Mexico and Spain. A total of 2,629 adults from Mexico and 4,583 from Spain were interviewed. Information was obtained using an abbreviated version of the DRM, which had been translated into Spanish. Reliability, validity, and the structure of affect were assessed and compared between countries. The diurnal variation of affect, the changes in affect along the life span, time use, and the relationship between affect and socio-demographic characteristics were also analysed. Adequate psychometric properties for the Spanish-language version of the abbreviated DRM were found in both the Mexican and the Spanish samples, and affect tended to improve along the life span in both countries. However, net affect did not have the same distribution function (Kolmogorov–Smirnov statistic = 0.25, p < 0.001) in both countries, being higher in Spain. Moreover, both samples showed opposite patterns in the diurnal variation of affect. The results showed that the Spanish-language version of the DRM is a feasible and valid method to measure affect, its diurnal rhythms, and time use in large-scale surveys.

Gender Differences in Psychological Well-Being in Emerging Adulthood

Gender is recognized as an important social determinant of health, but past research on gender differences in psychological well-being have not produced conclusive results. This study investigated gender differences in eudaimonic well-being and life satisfaction in emerging adulthood. A cross-sectional study with a sample of 1990 emerging adults (50% males) from the Spanish general population was conducted. Participants were assessed through five questionnaires. Results showed that women scored higher than men in purpose in life and personal growth. Hierarchical multiple regression analysis revealed that the most important predictors of emerging adult men’s and women’s eudaimonic well-being and life satisfaction were higher self-confidence and lower negative self-evaluation. Other significant variables in the eudaimonic well-being of both women and men were higher score in the masculine/instrumental trait, higher emotional social support, higher educational level, and higher score in the feminine/expressive trait. Furthermore, higher instrumental social support was associated with eudaimonic well-being in females. Other predictors of women’s and men’s life satisfaction were higher score in the feminine/expressive trait, less age, higher educational level and higher instrumental social support. In addition, higher emotional social support was associated with life satisfaction in males. The results suggest that gender is important in the psychological well-being of people in emerging adulthood, although self-esteem and instrumental social support are, in both emerging adult women and men, the most important predictors of psychological well-being.
