Psicobiología del síndrome de Down

Resumen

En este artículo revisamos los conocimientos que existen en la actualidad sobre el síndrome de Down, atendiendo a todos aquellos aspectos que, por su relevancia, facilitan una mejor comprensión de esta cromosomopatía. Después de una breve reseña histórica, y tras definir lo que se entiende por síndrome de Down, pasamos a ocuparnos de la alteración genética que lo determina, así como de los factores que parecen estar relacionados con su origen. A continuación estudiamos las alteraciones específicas que acompañan a este síndrome, considerando principalmente los aspectos morfológicos externos, el problema de la hipotonía muscular y otros trastornos biomédicos, el retraso mental y las diversas anomalías neuroanatómicas y neurofisiológicas que presentan los sujetos afectados. Por último, indicamos las nuevas perspectivas que se abren en el estudio de esta alteración genética.     

Explicit Training in Human Values and Social Attitudes of Future Engineers in Spain

In Spain before the 1990s there was no clear and explicit comprehensive training for future engineers with regard to social responsibility and social commitment. Following the Spanish university curricular reform, which began in the early 1990s, a number of optional subjects became available to students, concerning science, technology and society (STS), international cooperation, the environment and sustainability. The latest redefinition of the Spanish curriculum in line with the Bologna agreements has reduced the number of non-obligatory subjects, but could lead to improving preparation for social responsibility due to the requirement that the design of curricula and the assessment of students should be based on competencies, some of which include human values and attitudes.     

Mirroring Activity in the Brain and Movement Determinant in the Rorschach Test

Human movement (M) responses to the Rorschach are related to cognitive sophistication, creativity, and empathy. Recent studies also link Ms to EEG-mu suppression, an index of mirroring activity in the brain. In this article, we further investigate the link between Ms and mu suppression by testing some clinical interpretative distinctions. Previously collected EEG data recorded during the administration of the Rorschach were reanalyzed. We hypothesized that (a) among several responses investigated, only M would be associated with mu suppression, and (b) Ms with active movement, ordinary form quality, or whole human figures would be most strongly associated with mu suppression. Hypothesis 1 was fully confirmed, thus supporting that the traditional interpretation of M has a neurobiological foundation. Hypothesis 2 was partially confirmed; that is, active Ms were associated with mu suppression more strongly than passive Ms (p < .05), but no other significant differences emerged. Clinical implications are discussed.     

The Relationship between Cultural Identification,Family Socialization and Adolescent Alcohol Use among Native American Families

The enculturation or teaching of Native American traditions to Native American adolescents has been incorporated into substance-use prevention interventions in recent decades; yet, little is known about how enculturation may impact substance use through family socialization. The current study aimed to test the relationship between family identification with Native American culture and alcohol use among Native American families residing on or near a reservation, and determine if this relationship was mediated by family socialization practices. To achieve this aim, data (n? =?2368) collected as part of the NIDA-funded Drug Use among Young American Indians was used. No direct relationship was found between identification with Native American culture and alcohol use. Native American culture had an indirect effect on substance use through family communication and parental monitoring, such that a higher identification with Native American culture was associated with more communication and less monitoring, which were associated with drinking behavior. Findings reveal that identification with Native American culture may be related to family socialization, a relationship that could be important to address when designing alcohol-use prevention interventions for this population.     

Web of Science production quality indicators of ten professors' at the area of personality, assessment and psychological treatment: additional contributions to Olivas-Ávila y Musi-Lechuga study

Rankings of scientific productivity are increasingly relevant both from an individual and a collective perspective. Therefore, making sure they are based on reliable and exhaustive information is really important. This study clearly shows that available rankings change dramatically when internationally acknowledged bibliometric indices are considered. Data from the 10 Professors belonging to the 'Personality, Assessment, and Psychological Treatment' Department considered in the recent analysis by Olivas-ávila y Musi-Lechuga ( Psicothema 2010. Vol. 22, no 4, pp. 909-916) are revisited here for illustrative purposes.     

Aversive and appetitive electrodermal classical conditioning using pictures as stimuli

The principal goal of this study was to verify whether it was possible to obtain both aversive and appetitive electrodermal classical conditioning, using pictures as conditioned stimuli (CS), and unconditioned stimuli (US). Additionally, we tried to verify whether, as a consequence of such conditioning, diminution of the unconditioned response (UR) was observed. With this aim, IAPS (?International Affective Picture System?) pictures were selected as stimuli. A picture showing a burnt face was used as the aversive US (USav), and a picture showing a scene with erotic content was used as the appetitive US (USap). As the aversive CS (CSav), and appetitive CS (CSap), two images with intermediate values of valence and arousal showing male faces were selected. In the experimental group, 10 CSav/USav and 10 CSap/USap trials were presented. In the control group 10 CSav, CSap, USav, and USap trials were presented in pseudorandom order. Skin conductance response (SCR) elicited by both the CSs and the USs was scored. Results showed aversive conditioning, but neither appetitive conditioning nor UR diminution. Problems to obtain conditioning using pictures as stimuli and possible options to overcome them in future research are discussed.     

States of Spiritual Awareness by Time,Activity, and Social Interaction

We explore how people experience the sacred in their everyday lives using a recently developed research technique—smartphone‐based experience sampling method (S‐ESM). The primary goal of our experience‐driven approach is to explore the contours and variations of spiritual awareness within people's day‐to‐day lives. We seek to better understand when and where spiritual awareness is likely to arise, and the contexts in which it is rare. Our smartphone‐based data allow us to track the many contexts in which an awareness of the sacred occurs, as reported in real time during people's normal daily activities. We parse out how immediate contextual factors and how people's more habitual behaviors are related to their spiritual experiences. This illuminates a wide range of factors that influence spiritual experiences that have not received much scholarly attention, and enables us to connect cutting‐edge quantitative methods with qualitative scholarship on spirituality. We hope this will open the door to the development of new theories of situated spiritual experience.     

The Joy of Sexism? A Multinational Investigation of Hostile and Benevolent Justifications for Gender Inequality and Their Relations to Subjective Well-Being

Previous research on system justification theory suggests that beliefs that rationalize inequalities are related to subjective well-being. We examine how “complementary” (hostile and benevolent) justifications of gender inequality may serve a palliative function for both men and women. Using multilevel modeling and data from 32 countries (N’s?=?362 to 5160), we find that relationships between hostile and benevolent justifications and life satisfaction are moderated by the degree of gender inequality at the national level. In relatively egalitarian nations, individuals who endorse “complementary” justifications are higher on life satisfaction compared to those who endorse an exclusively hostile justification. In nations with high gender inequality, there is no difference in life satisfaction for those who endorse exclusively hostile vs. complementary justifications.
