Within-individual variability in self-concepts and personality states: Applying density distribution and situation-behavior approaches across cultures

Within-individual variability in self-concepts and everyday personality states and affects was investigated in two experience sampling studies using density distribution and situation-behavior approaches. In all seven cultures sampled, within-individual variability was substantial and self-concept and personality state variability exhibited moderate convergence. Variability in personality and affect states was moderately predicted by perceived need satisfaction in the situations. The density distribution and situation-behavior approaches were moderately convergent in identifying the most variable individuals, but the pattern of cultural differences differed in the two methods. Contrary to cultural psychology perspectives, cultural differences in within-individual variability did not consistently correspond to cultural differences in individualism–collectivism, dialecticism, or tightness.

The Association Between Health and Cognitive Performance in a Population-Based Study of Older Adults: The Charlotte County Healthy Aging Study (CCHAS)

In the present study, the relationship between self-reports and objective measures of health status and measures of cognitive performance was examined. Participants consisted of 437 persons (M =72.91 years) from the Charlotte County Healthy Aging Study, a population-based sample of older adults. Cognitive performance was assessed by tests of episodic memory, perceptual speed, and attention. Health status was indexed by subjective ratings, self-reports, and objective measures. The health measures accounted for significant variance on both the Trailmaking A and B tests, accounting for a modest amount of variance (4.4% and 1.1%, respectively). The health measures were not significantly associated with performance on the measures of attention or episodic memory. The results suggest that health status is associated with processing speed to a greater degree than higher order cognitive processes.     

The intergenerational transmission of social exclusion and its detection in early childhood education

In this paper we analyse the relationship between the self-confidence manifested by 3-6 year old in the internal working model (evaluated by interview) and their adaptation to nursery environment observed by their teacher, along with the relationship between these variables and the social-economic disadvantage encountered by the families of the children. The study was carried out with 128 children (64 from families in deprived circumstances and 64 in the contrast group). The results show that children from families with serious problems of exclusion exhibit adaptation deficiencies in all of the assessed factors: competence and empathy, passiveness/isolation and antisocial behavior; in the interview, they also show less frequency of the secure model, and higher frequency in the destructured and avoidant models than in the contrast group. These differences can be interpreted as the origin of the exclusion and destructurisation that characterises the families in question.     

Brain and cognitive-behavioural development after asphyxia at term birth

Perinatal asphyxia occurs in approximately 1-6 per 1000 live full-term births. Different patterns of brain damage can result, though the relation of these patterns to long-term cognitive-behavioural outcome remains under investigation. The hippocampus is one brain region that can be damaged (typically not in isolation), and this site of damage has been implicated in two different long-term outcomes, cognitive memory impairment and the psychiatric disorder schizophrenia. Factors in addition to the acute episode of asphyxia likely contribute to these specific outcomes, making prediction difficult. Future studies that better document long-term cognitive-behavioural outcome, quantitatively identify patterns of brain injury over development and consider additional variables that may modulate the impact of asphyxia on cognitive and behavioural function will forward the goals of predicting long-term outcome and understanding the mechanisms by which it unfolds.     

Boston Naming Test: problems with administration and scoring

The poorly written administration and scoring instructions for the Boston Naming Test allow too wide a range of interpretations. Three different, seemingly correct interpretations of the scoring methods were compared. The results show that these methods can produce large differences in the total score.     

The Human Species Origin: Views of Biology Teachers from Three Latin American Countries

This paper intends to investigate whether the differences in country religiosity can influence biology teachers’ views about biological evolution, especially the human origin. Since Argentina, Brazil and Uruguay have differences in religiosity, teachers from these countries were asked to answer to the question of the European questionnaire BIOHEAD-CITIZEN: “The emergence of the human species (Homo sapiens) was just as improbable as the emergence of any other species.” From their answers, it was possible to estimate how biology teachers conceive the origin of the humankind, whether they perceive it as a natural phenomenon or a special event. The four Barbour’s categories concerning the relationship between science and religion (Conflict, Independence, Dialogue and Integration) were used to analyze the results in these three countries. Results showed that, in general, teachers of Uruguay (a secular country) and Argentina (a constitutional Catholic country) had a clearer position of separation between science and religion whereas the teachers of Brazil (with a relative secularism), tended to do not make a separation between science and religion. It could be concluded that the type of the teachers’ religion rather than the secularism of state is more influencial on building teachers’ views about human origin.     

Long-term exposure to environmental enrichment since youth prevents recognition memory decline and increases synaptic plasticity markers in aging

Aging-associated brain changes include functional alterations that are usually related with memory decline. Epidemiological reports show that a physically and intellectually active life provides a protective effect on this decline and delays the onset of several neurodegenerative diseases. The cellular mechanisms behind the behavioral-based therapies, such as environmental enrichment (EE) exposure, as a method for alleviating age-related memory impairments, are still unknown. Although some reports have shown the benefits of EE exposure in cognitive outcomes in old mice and in animals with experimental neurodegenerative conditions, the effects of lifelong animal exposure to EE have not been explored in detail. In the present work we tested in a rat model the effects of intermittent lifelong exposure since youth to EE on behavioral performance, object recognition memory and anxiety level, as well as on some morphological and biochemical markers of brain plasticity such as hippocampal neurogenesis, synaptophysin content and synaptic morphology. We found that environmental factors have a positive impact on short-memory preservation, as well as on the maintenance of synapses and in the increase in number of new generated neurons within the hippocampus during aging.
