The effects of age and emotional valence on recognition memory: An ex‐Gaussian components analysis

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex‐Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex‐Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.     

Working memory and two-digit number processing

The processing of two-digit numbers in comparison tasks involves the activation and manipulation of magnitude information to decide which number is larger. The present study explored the role of different working memory (WM) components and skills in the processing of two-digit numbers by examining the unit–decade compatibility effect with Arabic digits and number words. In the study, the unit–decade compatibility effect and different WM components were evaluated. The results indicated that the unit–decade compatibility effect was associated to specific WM skills depending on the number format (Arabic digits and number words). We discussed the implications of these results for the decomposed view of two-digit numbers.     

The processing of Arabic numbers is under cognitive control

In this study, we evaluated whether the processing of two-digit Arabic numbers is subject to cognitive control. Participants performed a number comparison task with unit–decade compatible trials (36–47) and unit–decade incompatible number pairs (37–46). The unit–decade compatibility (incompatible minus compatible trials) was considered an index of conflict situation in numerical processing. To examine whether participants adapted to numerical conflict, we manipulated the percentage of incompatible trials relative to the percentage of compatible trials (20, 50, 80 % incompatible trials). The unit–decade compatibility effect was modulated by the amount of incompatible trials: the compatibility effect decreased progressively as the percentage of incompatible trials increased. This result indicated that participants adapted to numerical conflict. The findings are discussed in terms of cognitive control. Implications for models of two-digit number processing are also addressed.     

Schizophrenia and automatic processing: an exploratory study

This study deals with the schizophrenic deficit as one of automatic processing. To test the idea, a special experimental task was designed on which 21 schizophrenics, 21 depressives, and 21 normal subjects had to complete a series of simple geometric figures. When the subjects had thoroughly learned this activity, another information source, a brief story, was introduced, and the subjects had to pay attention to the story while they did the task. Two dependent variables were considered, execution time and performance. There were no differences among the three groups in the first experimental condition; but in the second condition, when the distractor was introduced, schizophrenics needed more time to do the task and their performance was noticeably worse than those of both normals and depressives. This outcome is explained in terms of a failure in the internal mechanisms which regulate the automatic, parallel, and unconscious processing.     

Factors Associated with Psychological Maladjustment of Mexican Adolescents Living in Poverty

The objectives of this study were to test the replicability of the Youth Self-Report structure in Mexican adolescents living in poverty; to determine gender and rurality differences in internalizing and externalizing problems; and to identify predictors of internalizing and externalizing problems. Data were collected from a probabilistic sample of households that are beneficiaries of the Oportunidades program, including the heads of those households, their spouses and their adolescent children. The self-reports of parents and children were analyzed using structural equation modeling. Results confirmed the Youth Self-Report structure in Mexican adolescents, and indicated higher levels of emotional disorders in females, higher levels of behavioral disorders in males, and higher levels in all the Youth Self-Report scales in rural adolescents. Internalizing and externalizing problems were mediated by the presence of loneliness, oppositional behavior and stress, through which the model’s other latent variables exerted indirect influence on the determination of youth psychopathology.     

More than Altruism: Cultural Norms and Remittances Among Hispanics in the USA

Cultural norms embody the communalism and familism that characterize social structures and traditions of care among certain identity groups, notably, Hispanics. In turn, they affect remitting behavior as they do family dynamics thereby extending care transnationally. Using the 2006 Latino National Survey, the largest instrument that captures socioeconomic variables and political perspectives among Hispanics residing in the USA, we constructed a Hispanic identity index that is used to capture the role of cultural norms in remittance behavior. This index is used as an explanatory variable in a logit model for the probability and frequency of remitting money. We find that both the probability and frequency of remitting increase with higher levels of self-defined familism as reflected by the Hispanic index. This effect is stronger among males, renters, foreign-born non-US citizens, and migrants with fewer years of residence in the USA. Incorporating variables such as our Hispanic identity index may shed light on a relatively unexplored area in the field of economics that explains remitting behavior.     

The challenge of measuring immigrant origin and immigration-related ethnicity in Europe

Different European nation-states use the most diverse statistical constructions of foreign origin or ethnic minority populations. Several countries traditionally even shun from producing such data. This makes international comparison a very difficult endeavour. Anyone wanting to perform comparative research on immigrants or (immigrant origin) ethnic minorities in Europe is unavoidably confronted with the most diverse types of national statistical data and has to opt for ad hoc solutions. Attempts at international comparison can thus be very tricky due to data characteristics. It is important that researchers are aware of these problems and do not simply accept data (especially in comparisons) at face value. In this article we embark on a comparative explorative study of the way in which immigrant background and immigration related ethnicity is taken stock of by national statistical institutes in a set of European nation-states.     

Effect sizes and cut-off points: a meta-analytical review of burnout in latin American countries

Burnout is a highly prevalent globalized health issue that causes significant physical and psychological health problems. In Latin America research on this topic has increased in recent years, however there are no studies comparing results across countries, nor normative reference cut-offs. The present meta-analysis examines the intensity of burnout (emotional exhaustion, cynicism and personal accomplishment) in 58 adult nonclinical samples from 8 countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru and Venezuela). We found low intensity of burnout but there are significant differences between countries in emotional exhaustion explained by occupation and language. Social and human service professionals (police officers, social workers, public administration staff) are more exhausted than health professionals (physicians, nurses) or teachers. The samples with Portuguese language score higher in emotional exhaustion than Spanish, supporting the theory of cultural relativism. Demographics (sex, age) and study variables (sample size, instrument), were not found significant to predict burnout. The effect size and confidence intervals found are proposed as a useful baseline for research and medical diagnosis of burnout in Latin American countries.     

Interactive patterns detection in family communication with adolescents

Interactive patterns detection in family communication with adolescents. Nondistant communication is a relevant indicator for family functionality valuation. The goal of this study is to analyze this communication in order to identify specific kinds of leadership, interaction patterns and the relation between verbal and nonverbal elements in communication. The observational design exposed is an idiographic one, punctual and multidimensional, which uses field format as observation instrument. Participants were seven standardized families made up of both ancestors and an adolescent son or daughter. According to the family models analyzed, results show a predominantly democratic communication style in adults with recurrent support expressions. The sequential analysis incorporates only categories from the emitter point of view, and detects relevant sequences which show symmetric interaction between all three family members. Verbal and nonverbal channels provide complementary information. Depending on adolescents' gender different patterns in behaviour can be identified as well.
