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.     

From aesthetics to ethics: Testing the link between an emotional experience of awe and the motive of quixoteism on (un)ethical behavior

Motivation and Emotion - According to the awe-quixoteism hypothesis, one experience of awe may lead to the engagement in challenging actions aimed at increasing the welfare of the world. However,...     

Justification and Cognitive Algorithms

In this paper, we offer an alternative interpretation for the claim that ‘S is justified in believing that φ’. First, we present what seems to be a common way of interpreting this claim: as an attribution of propositional justification. According to this interpretation, being justified is just a matter of having confirming evidence. We present a type of case that does not fit well with the standard concept, where considerations about cognition are made relevant. The concept of cognitive algorithm is presented and explained. Finally, the new reading of ‘S is justified in believing that φ’ is fleshed out. According to this interpretation, being justified in believing that φ is not just a matter of having evidence in favor of φ, but also of having a cognitive algorithm available such that it allows one to form belief in φ on the basis of the relevant evidence.     

Terms of the debate on the format and structure of visual memory

Our ability to actively maintain information in visual memory is strikingly limited. There is considerable debate about why this is so. As with many questions in psychology, the debate is framed dichotomously: Is visual working memory limited because it is supported by only a small handful of discrete “slots” into which visual representations are placed, or is it because there is an insufficient supply of a “resource” that is flexibly shared among visual representations? Here, we argue that this dichotomous framing obscures a set of at least eight underlying questions. Separately considering each question reveals a rich hypothesis space that will be useful for building a comprehensive model of visual working memory. The questions regard (1) an upper limit on the number of represented items, (2) the quantization of the memory commodity, (3) the relationship between how many items are stored and how well they are stored, (4) whether the number of stored items completely determines the fidelity of a representation (vs. fidelity being stochastic or variable), (5) the flexibility with which the memory commodity can be assigned or reassigned to items, (6) the format of the memory representation, (7) how working memories are formed, and (8) how memory representations are used to make responses in behavioral tasks. We reframe the debate in terms of these eight underlying questions, placing slot and resource models as poles in a more expansive theoretical space.     

Segmented Paths? Mexican Generational Differences in the Transition to First-Time Homeownership in the United States

Homeownership represents an important indicator of immigrant incorporation and assimilation. This study is a longitudinal analysis of the transition to first-time homeownership among a cohort of youths followed from 1979 to 2009 using the National Longitudinal Survey of Youth (NLSY, 1979). In particular, I examine Mexican generational group differences in the transition to first-time homeownership over an observation period that spans 30 years while evaluating theories of straight-line and segmented assimilation. I find that Mexican homeownership rates do not increase in a linear fashion across generations, relative to native, non-Hispanic whites, even after controlling for various social, demographic, and economic characteristics. Furthermore, analyses limited to Mexicans reveal that first- and second-generation respondents exhibit more success in the transition to first-time homeownership than their third-generation counterparts. Contrary to observing linear gains in homeownership across generations, I find that Mexicans are experiencing segmented paths towards homeownership and achieving upward mobility across generations.     

My Life as a Psychoanalyst in Spain

This article attempts to explain, in a necessarily brief way, the reasons underlying my choice of the psychiatry specialty: why I chose the psychoanalytically oriented psychotherapy, the authors and theories that have influenced me the most, and my current professional situation, making some allusion to my hobbies.     

Psychic Truth and the In-Session Work of the Analyst

I seek to address one of the issues most affected by the postmodern culture, such as the crisis of rationality and truth, and try to reformulate its place within the psychoanalytic clinic using the contributions of Freud and Ferenczi, who drew the matrix of a passionate dialogue about the truth and the analyst work that has nurtured many contemporary theoretical developments. Essentially, the major influences of postmodern thought in psychoanalysis are to emphasize the importance of the patient–analyst interaction, the role played by the analyst in the patient’s transference and the rejection of the model of the analyst as a distant observer who interprets without having anything to do with whatever happens within the mind of the patient. Consequently, because both postmodernism and psychoanalysis are concerned with human subjectivity and love for truth, although indeed understanding them from different perspectives, both schools of thought become easily interrelated. I conclude that psychoanalysis, committed as it is with the search for truth, cannot ignore the influence of postmodern thought, as well as the postmodernist movement should not disregard all theoretical consistency provided by psychoanalytic theory and metapsychology.
