This study assessed the influence of clinical and socio-demographic variables on the psychological adaptation of transplanted adolescents. Twenty-six transplanted adolescents and 25 healthy adolescents, aged 13–17, and their parents participated in the study. The following domains were measured: social competence, emotional/behavioral problems, self-concept, self-esteem and subjective well-being. The findings revealed that transplanted boys presented significantly less social competence (U = 26,000, p < .05) and more externalizing problems (U = 25,000, p < .05), social problems (U = 25,000, p < .05) and attention problems (U = 17,500, p < .01) than healthy boys. In contrast, transplanted girls displayed significantly more internalizing problems (U = 47,000, p < .05) and lower physical self-concept (U = 49,500, p < .05) than healthy girls. Hierarchical regression analysis showed clinical variables, especially waiting-list time, significantly predicted attention problems (β = .364, p < .05) and negative affect (β = .632, p < .05) in transplanted adolescents. Also, male (β = −0.554, p < .01) and younger (β = −0.444, p < .01) transplanted adolescents were at risk for attention problems. Our data suggest the importance of the waiting-list time for transplanted adolescents. Efforts to reduce the pretransplant phase would help adolescents achieve better psychological adaptation at long-term posttransplant.  相似文献

Excessive alcohol consumption increases the years of life lost to premature death and disability worldwide. Religion is a mitigating factor in alcohol consumption. A survey in the Dominican Republic showed increasing church attendance by middle and high school students (N = 3,478) was associated with a delay in age at first alcoholic drink, fewer students who had consumed alcohol in the past month (current drinkers), lower alcohol consumption levels, fewer episodes of inebriation, and less heavy episodic alcohol consumption (all P < 0.0001). The results suggested that it may be useful to conceive of church-attending youth as a subset of the adolescent social network when planning primary alcohol prevention programs for young people.  相似文献

Chunk learning (the process by which a sequence is learned and retrieved from memory in smaller, decomposed units of information) has been postulated as the main learning mechanism underlying sequence learning (Perruchet & Pacton, 2006). However, the evidence for chunk formation has been elusive in the continuous serial reaction-time task, whereas other continuous, statistical processes of learning account well for the results observed in this task. This article proposes a new index to capture segmentation in learning, based on the variance of responding to different parts of a sequence. We assess the validity of this measure by comparing performance in a control group with that of another group in which color codes were used to induce a uniform segmentation. Results showed that evidence of chunking was obtained when the color codes were consistently coupled to responses, but that chunking was not maintained after the colors were removed.  相似文献

Several studies have indicated that dyslexics show a deficit in speech perception (SP). The main purpose of this research is to determine the development of SP in dyslexics and normal readers paired by grades from 2nd to 6th grade of primary school and to know whether the phonetic contrasts that are relevant for SP change during development, taking into account the individual differences. The achievement of both groups was compared in the phonetic tasks: voicing contrast, place of articulation contrast and manner of articulation contrast. The results showed that the dyslexic performed poorer than the normal readers in SP. In place of articulation contrast, the developmental pattern is similar in both groups but not in voicing and manner of articulation. Manner of articulation has more influence on SP, and its development is higher than the other contrast tasks in both groups.  相似文献

This study analyzed the genetic and environmental influences on internalizing and externalizing behavior problems and the nature of their cooccurrence in a national Norwegian twin sample. The sample comprised 526 identical and 389 fraternal same-sexed twin pairs from five birth cohorts, aged 5-6, 8-9, 12-13, 13-14, and 14-15 years. Behavior problems were assessed by parental ratings on the Child Behavior Checklist. A model of additive genetic, shared, and nonshared environmental influences was fitted to both internalizing and externalizing behavior in four sex and age groups. The considerable covariance,r = .51 to .58, between these traits is accounted for mainly by common environmental components; this effect was most marked in the 5 to 9-year olds. Concordance rates for children scoring above 1 standard deviation from the total sample mean on the internalizing scale only, externalizing scale only, or both indicated stronger genetic influences for internalizing or externalizing problems only than for combined problems.  相似文献

This paper examines the ideological asymmetry hypothesis with respect tothe interface between legitimizing ideologies and psychological attachment to one's ethnic group. The ideological asymmetry hypothesis suggests that hierarchy-enhancing legitimizing ideologies should be positively associated with ingroup attachment among high-status groups, but that among low-status groups these associations should be either less positive in magnitude (isotropic asymmetry) relative to high-status groups or negative in direction (anisotropic asymmetry). The opposite pattern should be found with respect to the interface between hierarchy-attenuating legitimizing ideologies and ingroup attachment: Among high-status groups these associations should be negative, but among low-status groups these associations should be either less negative in magnitude (isotropic asymmetry) relative to high-status groups or positive in direction (anisotropic asymmetry). The presence of isotropic versus anisotropic asymmetry is hypothesized to depend on the degree of disparity in status between the groups being compared: Wider status gaps should tend toward anisotropic asymmetries. The relationships between legitimizing ideologies and ingroup attachment were compared for (1) relatively high-status ethnic groups (European and Asian Americans) versus relatively low-status ethnic groups (Latinos and African Americans) in the United States, (2) the higher-status Jewish ethnic group (Ashkenazim) versus the lower-status Jewish ethnic group (Mizrachim) in Israel, and (3) the high-status Israeli Jews versus the low-status Israeli Arabs. The data were largely consistent with the ideological asymmetry hypothesis. The implications of these findings are discussed within the theoretical frameworks of social dominance theory and other approaches to intergroup relations.  相似文献

Gilbert Harman, in Logic and Reasoning (Synthese 60 (1984), 107–127) describes an unsuccessful attempt ... to develop a theory which would give logic a special role in reasoning. Here reasoning is psychological, a procedure for revising one's beliefs. In the present paper, I construe reasoning sociologically, as a process of linguistic interaction; and show how both reasoning in the psychologistic sense and logic are related to that process.  相似文献
