BIOLOGY TEACHERS’ CONCEPTIONS ABOUT THE ORIGIN OF LIFE IN BRAZIL,ARGENTINA, AND URUGUAY: A COMPARATIVE STUDY

Teachers’ conceptions about the origin of life in three Latin American countries with contrasting levels of secularism were analyzed: Argentina (Catholic constitution), Brazil (formally secular but not in practice), and Uruguay (consolidated secularism). A European survey questionnaire was used and the interpretation of the results drew on Barbour's four categories concerning the relationships of science and religion. A large majority of Argentinian and Uruguayan teachers were clearly evolutionist, even when believing in God (Independence or Dialogue category), with no difference between Argentina and Uruguay. The majority of Brazilian teachers assumed a religious position about the origin of life, being creationist (Conflict or Independence categories) or evolutionary creationist (Dialogue or Integration categories). Differences of Brazilian teachers’ conceptions may result from the higher percentage of evangelicals and lower proportion of agnostics/atheists. Brazilian Catholic teachers were more creationist than their Catholic colleagues in Argentina and Uruguay. Distinct patterns were found, but further research is needed to understand possible classroom impacts.     

Knowledge before Gettier

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance.     

Dysexecutive syndrome in Parkinson’s disease: the GREFEX study

The objectives of this study were to characterize the frequencies and profiles of behavioral and cognitive dysexecutive syndromes in PD (based on validated battery and diagnostic criteria) and to develop a shortened diagnostic battery. Eighty-eight non-demented patients with a diagnosis of PD were examined with an executive validated battery. Using a validated framework, the patients’ test results were interpreted with respect to normative data from 780 controls. A dysexecutive syndrome was observed in 80.6% of the patients [95% confidence interval: 71.1–90.1]. The dysexecutive profile was characterized by prominent impairments in deduction, flexibility, inhibition and initiation in the cognitive domain, and by global hypoactivity with apathy and hyperactivity in the behavioral domain. This finding implies that patients with PD should be assessed with cognitive tests and a validated inventory for behavioral dysexecutive syndromes. A shortened battery (based on three cognitive tests and three behavioral domains) provided high diagnostic accuracy.     

Impairment in holistic face processing following early visual deprivation

Unlike most objects, faces are processed holistically: They are processed as a whole rather than as a collection of independent features. We examined the role of early visual experience in the development of this type of processing of faces by using the composite-face task, a measure of holistic processing, to test patients deprived of visual experience during infancy. Visually normal control subjects showed the expected composite-face effect: They had difficulty perceiving that the top halves of two faces were the same when the top halves were aligned with different bottom halves. Performance improved when holistic processing was disrupted by misaligning the top and bottom halves. Deprived patients, in contrast, showed no evidence of holistic processing, and in fact performed significantly better than control subjects when top and bottom halves were aligned. These findings suggest that early visual experience is necessary to set up or maintain the neural substrate that leads to holistic processing of faces.     

Relationship building in Clinical Pastoral Education: a Confucian reflection from Asian chaplains

The authors reflect on the intentional model of relationship building in Clinical Pastoral Education (CPE) and its roots in the Western concept of the self as a rational, autonomous, and bounded agent. They compare the Western idea to the Confucian two-dimensional self orientation as relational as well as autonomous, and discuss possible difficulties that Asian students from Confucian background may encounter entering CPE. The chaplains explore implications and suggestions for how CPE supervisors and students may enter into dialogue in order to create mutual understanding and help Asian students translate CPE learning methods into meaningful cultural contexts.     

Developmental changes in face processing skills

Expertise in processing differences among faces in the spacing among facial features (second-order relations) is slower to develop than expertise in processing the shape of individual features or the shape of the external contour. To determine the impact of the slow development of sensitivity to second-order relations on various face-processing skills, we developed five computerized tasks that require matching faces on the basis of identity (with changed facial expression or head orientation), facial expression, gaze direction, and sound being spoken. In Experiment 1, we evaluated the influence of second-order relations on performance on each task by presenting them to adults (N=48) who viewed the faces either upright or inverted. Previous studies have shown that inversion has a larger effect on tasks that require processing the spacing among features than it does on tasks that can be solved by processing the shape of individual features. Adults showed an inversion effect for only one task: matching facial identity when there was a change in head orientation. In Experiment 2, we administered the same tasks to children aged 6, 8, and 10 years (N=72). Compared to adults, 6-year-olds made more errors on every task and 8-year-olds made more errors on three of the five tasks: matching direction of gaze and the two facial identity tasks. Ten-year-olds made more errors than adults on only one task: matching facial identity when there was a change in head orientation (e.g., from frontal to tilted up). Together, the results indicate that the slow development of sensitivity to second-order relations causes children to be especially poor at recognizing the identity of a face when it is seen in a new orientation.     

Assessing short summaries with human judgments procedure and latent semantic analysis in narrative and expository texts

In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries, summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence text). A total of 390 Spanish middle and high school students (14–16 years old) and six experts read a narrative or expository text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository, and LSA correlated more with human content ratings than with human coherence ratings. Finally, the holistic methods were found to be more reliable than the componential methods analyzed in this study.     

Searching for a developmental typology of personality and its relations to antisocial behavior: a longitudinal study of a representative sample of men

The search for an empirically based personality typology has regained the interest of researchers. To date, however, the empirical inquiries were mainly cross-sectional. In this study, an empirically based developmental typology of personality was identified using data from a prospective longitudinal study of a representative sample of men assessed on four occasions from adolescence to midlife. Cluster analyses were performed on measures of Disinhibition, Negative Emotionality, and Extraversion. Four developmental types of personality were identified. The first was characterized by average scores in the three traits in adolescence that decreased rapidly until midlife (38%). The second was similar, but, instead, displayed increases in Extraversion during adulthood (32%). The third type showed high scores in Disinhibition and Negative Emotionality in adolescence that decreased progressively until midlife (23%). The fourth type was characterized by average scores in the three traits during adolescence followed by important increases in Negative Emotionality and decreases in Extraversion during adulthood (7%). These four developmental types of personality seemed to be related to known antisocial behavior trajectories.     

A meta-analysis on the correlation between the implicit association test and explicit self-report measures

Theoretically, low correlations between implicit and explicit measures can be due to (a) motivational biases in explicit self reports, (b) lack of introspective access to implicitly assessed representations, (c) factors influencing the retrieval of information from memory, (d) method-related characteristics of the two measures, or (e) complete independence of the underlying constructs. The present study addressed these questions from a meta-analytic perspective, investigating the correlation between the Implicit Association Test (IAT) and explicit self-report measures. Based on a sample of 126 studies, the mean effect size was .24, with approximately half of the variability across correlations attributable to moderator variables. Correlations systematically increased as a function of (a) increasing spontaneity of self-reports and (b) increasing conceptual correspondence between measures. These results suggest that implicit and explicit measures are generally related but that higher order inferences and lack of conceptual correspondence can reduce the influence of automatic associations on explicit self-reports.
