Infants' discrimination of internal and external pattern elements

Human infants' discrimination of changes in internal and external elements of compound visual patterns was investigated in four experiments employing a familiarization-novelty paradigm in which visual reinforcing patterns were presented contingent upon rate of high-amplitude nonnutritive sucking. In Experiment 1, 4-month infants discriminated changes in the shape of internal, external and both internal and external figures. One-month infants discriminated external changes in both internal and external figures, but failed to show reliable response recovery when only internal figures were changed. Experiments 2 and 3 failed to explain the 1-month results on the basis of poor resolution of internal figures by showing comparable discrimination of small and large singly-presented figures and by failing to find improved internal discrimination with large separation between internal and external figures. In Experiment 4, 1-month infants showed response recovery to figure additions made adjacent to the initial figure, but not to internal additions. The results are interpreted in terms of attentiveness by young infants to external pattern elements and may indicate early processing of figure-ground information. The developmental differences observed suggest an increased breadth of attention to pattern elements.     

Development of combinatory manipulation in chimpanzee infants (Pan troglodytes)

I made systematic observations of three infant chimpanzees aged 2–4 years, who participated in a series of diagnostic tests of combinatory manipulation. The tasks were stacking blocks, seriating nesting cups, and inserting an object into the corresponding hole in a plate or a box. These tasks were originally devised for developmental diagnosis of human infants. The chimpanzee infants displayed combinatory manipulation comparable to that of 1-year-old human infants. Common motor characteristics were observed across the tasks, namely "repetition" of actions, "adjustment" of actions, "reversal" of actions, and "shifts" of attention. Humans and chimpanzees share these actions when manipulating multiple objects to complete a task. Repetition, adjustment, and reversal of actions and shifts of attention underlie higher levels of cognition common to both species. Accepted after revision: 5 May 2001 Electronic Publication     

The mediating role of identity incompatibility in the relationship between perceived discrimination and acculturation preferences in two generations of the ethnic Russian minority in the North Caucasus

Abstract

The present study tested a model in which the perceived incompatibility of ethnic Russian and regional North Caucasian identities mediates the relationship between perceived discrimination and acculturation strategies in two generations of ethnic Russian minority members living in the Kabardino-Balkar Republic, North Caucasus, Russian Federation. Two identities might be perceived incompatible when they represent conflicting sets of norms and values and the two communities may place competing demands on individual commitment and loyalty. We sampled 105 dyads from ethnic Russian families (youth: M = 18 years, SD = 2.35, 48.6% female; parents: M = 43 years, SD = 6.97, 68.6% female). The questionnaire included measures of perceived discrimination, perceived identity incompatibility, and acculturation strategies. The results of multigroup path analysis showed that the perceived identity incompatibility mediated the relationship between perceived discrimination and two strategies, aimed at culture maintenance (integration and separation) in both generations. Identity incompatibility is regarded as a psychological mechanism that explains the impact of perceived discrimination on minority acculturation preferences in a multicultural region.     

From Mecca with tolerance: religion,social recategorisation and social capital

Does participation in mass religious rituals promote intergroup conflict or does it promote intergroup tolerance? We assess these claims by examining the effects of the annual pilgrimage to Mecca (the hajj) on sociopolitical views of Muslims in Russia’s North Caucasus. Participant observation during the hajj and a quasi-experimental focus group study of pilgrims and non-pilgrims produced paradoxical findings. While the hajj strengthened their ingroup pride as Muslims, the pilgrims came through as more outgroup-tolerant and prosocial than the non-pilgrims. We develop a synthetic theoretical solution: in high-identity-value, high-diversity common group settings social recategorisation and social capital become transitive – that is, inclusive views and social capital effects within an ingroup extend to outgroups. This means that intergroup conflict could be reduced by not only maximising contact across conflicting groups, but also by bringing together as many subgroups as possible within each conflicting group in settings where their common identity is positively affirmed in a non-discriminatory fashion.     

Motivation for Physical Activity among Hawaiian,Japanese, and Filipino University Students in Hawaii

The purpose is to identify the motivations and barriers to physical activity (PA) among the three largest ethnic groups in Hawaii (Hawaiians/part-Hawaiians, Japanese, and Filipinos). University of Hawai'i students (N = 32, aged 18+) self-identified as one of those ethnicities participated in focus groups. There are more common themes than ethnic-specific variations in factors influencing PA. PA is understood as exercise among all groups; leisure time PA like running and surfing are common activities. Results were more similar among Hawaiian and Japanese than with Filipino participants. The findings offer an opportunity for improving cross-cultural and culture-specific PA interventions for those ethnicities.     

The Developmental Activities of Elite Ice Hockey Players

The purpose of this study was to analyze the development of four 20 year-old elite hockey players through an in-depth examination of their sporting activities. The theoretical frameworkof deliberate practice (Ericsson, Krampe, & Tesch-Romer, 1993) and the notion of deliberate play (Côté, 1999) served as the theoretical foundations. Interviews were conducted to providea longitudinal and detailed account of each participant.s involvement in various sporting activities. The interviewer asked questions about the conditions and sporting activities for eachyear of development. The data obtained were validated through independent interviews conducted with three parents of three different athletes. The results were consistent with Côté.s(1999) three stages of development in sport: the sampling (age 6.12), specializing (age 13. 15), and investment (age 16+) years.     

Slavery on the Frontier

Abstract

This document is a report sent in 1654 by Jean Le Vacher, member of the Congregation of the Mission, vicar apostolic of the Holy See and acting French consul in Tunis, to the cardinals of the Congregation for the Propagation of the Faith, in Rome. It describe his missionary work in and around Tunis. Le Vacher’s letter focuses on the life and conditions of the Christian slaves (mostly Catholic, but Protestant too) in the region and on his efforts to provide spiritual and material assistance to them. It offers insights into early modern slavery in North Africa, the efforts of the Catholic Church to strengthen its presence in the area, and the culture and organisation of societies on the border between Islam and Christianity. This presentation includes the full text of Le Vacher’s report in the original Italian and in English translation, together with an introduction, commentary, and editorial notes.     

Sex stereotypes in occupational choice: The case for college women

The choice of a male dominated occupation rather than a traditionally feminine one is the single occupational variable which meaningfully divides a class of women who were studied intensively over the 4 yr of college. Women who choose occupations which employ largely men differ predictably from women who select feminine occupations in terms of familial influence, work values, work experience, role model influence and some collegiate activities. The two groups do not differ appreciably in sociability experiences or in relationships with parents, so it cannot be argued that the work plans of the pioneer women stem from social isolation, rejection, or lack of appropriate feminine socialization.     

Dry-bed training: rapid elimination of childhood enuresis

Enuresis has been treated with moderate effectiveness by the urine-alarm method which requires many weeks of training. The present procedure used a urine-alarm apparatus but added such features as training in inhibiting urination, positive reinforcement for correct urinations, training in rapid awakening, increased fluid intake, increased social motivation to be nonenuretic, self-correction of accidents, and practice in toileting. After one all-night training session, the 24 enuretic children averaged only two bedwettings before achieving fourteen consecutive dry nights and had no major relapses. Little or no reduction in bedwetting occurred within the first two weeks for matched-control enuretics who were given the standard urine-alarm training. The results of a control-procedure showed that the new procedure did not involve Pavlovian conditioning. The new method appears to be a more rapid, effective and different type of treatment for enuresis.
