Biologically embedded experiences alter developmental trajectories in ways that can influence health, learning, and/or behavior. These systematic differences in experiences may contribute to different biological outcomes as individuals grow and develop, including at the neural level. Previous studies of biologically embedded experiences on neurodevelopment have focused on large‐scale institutional or economic factors (e.g. socioeconomic status [SES]) and psychosocial factors (e.g. caregiving behavior). Less attention has focused on how the quality of the immediate home settings, such as the physical home environment (PHYS), influences neurodevelopment. Moreover, no study has investigated these effects in adolescents, who undergo significant physical maturation and neurodevelopment that may influence how they respond to their physical environments. The goal of the current study was to examine whether PHYS quality is biologically embedded in the developing adolescent brain as evidenced by cognitive achievement and cortical development in 56 (48% female) healthy adolescents (14–18 years (M = 16.83 years, SD = 1.17). Using in‐home assessments of the physical home environment, anatomical brain scans, and indices of academic achievement, we found that adolescents who have more physical problems in the home (e.g. structural hazards, crowding, excessive noise, poorly lit) have thinner prefrontal cortices, which was associated with lower levels of reading achievement, independent of SES and psychosocial factors. By conducting home visits to assess physical characteristics of adolescents’ home, we highlight a typically overlooked aspect of the home environment that has relevance for adolescents’ cognitive and brain development. 相似文献

Background/ObjectiveTo test the effectiveness of an 8-week before-school physical activity program to reduce bullying victimization among a group of socially disadvantaged children in the Active-Start study.MethodA non-blinded randomized controlled trial was conducted in three public schools classified as highly vulnerable and located in a deprived area of Santiago (Chile). A total of 5 classes participated, totaling 170 fourth grade children. The intervention was delivered before starting the first school-class (8:00–8:30 a.m.). The program lasted for 8 weeks. Primary outcome measurement on bullying victimization was assessed by the CUBE questionnaire at baseline and post-intervention.ResultsThere was a statistically significant reduction in the probability of suffering physical bullying (OR= 0.18, 95% CI, 0.04-0.82; p= .027) and verbal bullying (OR=0.13, 95% CI, 0.02-0.97; p= .046) after the 8-week program.ConclusionsParticipation in an 8-week before-school physical activity intervention implemented in schools located in a disadvantaged district in Santiago (Chile) resulted in lower levels of bullying victimization among study participants. The Active-Start program may be a feasible and potentially scalable intervention option to improve the climate and pro-sociality environment at schools. 相似文献

Noncontingent reinforcement is a commonly used procedure to decrease levels of problem behavior. Goals of this intervention are to decrease motivation, responding, and the functional relation between behavior and consequences, but it could also possibly compete with performance of alternative desirable responses. In the current study, we assessed the effects of noncontingent reinforcement arranged from 0% to 100% of sessions on performance of alternative responding across two experiments. Experiment 1 assessed manding (i.e., requests) maintained by attention and tangibles with a child with developmental disabilities and Experiment 2 assessed keypecking maintained by food with six pigeons. We extended previous research by (a) showing that noncontingent reinforcement competes with both the acquisition and maintenance (performance) of an alternative response, (b) extending the generality of the findings across nonhuman and human participants, and (c) eliminating influence of sequence effects through random manipulations of noncontingent value in pigeons. Overall, greater amounts of noncontingent reinforcement competed with both acquisition and maintenance of alternative responding. 相似文献

In this article some usually overlooked aspects of Vygotsky’s work are presented. First, the understanding of the mediation system as a trans-organic, extended branch of the psychological system. Second, the semantic nature of conscience and the systemic neuropsychological organization of higher functions. Third, the leading role played in the psychic system by directive functions. Fourth, the understanding of human evolution as open and permanently provisional. Last, a reference is made to the role of psychology in the process of human auto-evolution, which Vygotsky viewed as a mission. 相似文献

Anxiety disorders are one of the most widespread psychological diseases in adolescence, which may lead to impairment in several areas of life and has been demonstrated a risk factor of other psychiatric disorders. One of the most widely used self-report measures to assess multiple symptoms of anxiety in youth is the Spence Children’s Anxiety Scale (SCAS). Literature suggests that anxiety symptoms vary across cultures to some extent. It has been found that individuals from collectivistic culture report higher levels of anxiety disorders than those from individualistic culture. Poland is a country whose culture was traditionally collectivistic; but now Poland is undergoing social and economic system transformation, which is taking it closer to individualistic culture. However, SCAS has never been validated in Polish samples, and thus the current study aimed (1) to assess the psychometric properties (structural validity and reliability) of SCAS in a sample of 303 Polish adolescents, (2) to examine gender differences, (3) to test the divergent validity of SCAS by relating it to the Rosenberg Self-Esteem Scale, and (4) to compare the mean levels with Chinese (collectivistic) and Italian (individualistic) samples. The results confirmed that the Polish version of SCAS showed good reliability and validity. Polish girls showed higher physical injury and generalized anxiety/overanxious symptoms than boys. Furthermore, Polish adolescents reported higher levels of anxiety than Italian youth but lower levels of anxiety than their Chinese counterparts. Implications for professionals and researchers are discussed. 相似文献

The ventral striatum displays hyper‐responsiveness to reward in adolescents relative to other age groups, and animal research on the developmental trajectory of the dopaminergic system suggests that dopamine may underlie adolescent sensitivity to reward. However, practical limitations prevent the direct measurement of dopamine in healthy adolescents. Eye blink rate (EBR) shows promise as a proxy measure of striatal dopamine D2 receptor function. We investigated developmental differences in the relationship between EBR and reward‐seeking behavior on a risky decision‐making task. Increasing EBR was associated with greater reward maximization on the task for adolescent but not adult participants. Furthermore, adolescents demonstrated greater sensitivity to reward value than adults, as evinced by shifts in decision patterns based on increasing potential reward. These findings suggest that previously observed adolescent behavioral and neural hypersensitivity to reward may in fact be due to greater dopamine receptor activity, as represented by the relationship of blink rate and reward‐seeking behavior. They also demonstrate the feasibility and utility of using EBR as a proxy for dopamine in healthy youth in whom direct measurements of dopamine are prohibitively invasive. 相似文献

Trait and cultural psychology perspectives on cross-role consistency and its relation to adjustment were examined in 2 individualistic cultures, the United States (N=231) and Australia (N=195), and 4 collectivistic cultures, Mexico (N=199), the Philippines (N=195), Malaysia (N=217), and Japan (N=180). Cross-role consistency in trait ratings was evident in all cultures, supporting trait perspectives. Cultural comparisons of mean consistency provided support for cultural psychology perspectives as applied to East Asian cultures (i.e., Japan) but not collectivistic cultures more generally. Some but not all of the hypothesized predictors of consistency were supported across cultures. Cross-role consistency predicted aspects of adjustment in all cultures, but prediction was most reliable in the U.S. sample and weakest in the Japanese sample. Alternative constructs proposed by cultural psychologists--personality coherence, social appraisal, and relationship harmony--predicted adjustment in all cultures but were not, as hypothesized, better predictors of adjustment in collectivistic cultures than in individualistic cultures. 相似文献

The purpose of this study was to verify how and when body position and postural control affect hand-mouth and hand-hand behaviors in infants during their first 4 months of life. Forty healthy infants were positioned in supine, prone and side-lying positions so that frequency and duration of the behaviors were quantified. Postural control when in supine and prone was also analyzed. The prone position elicited hand-mouth behavior in 0-2-month-old infants. The side-lying position elicited hand-mouth behavior in 3-4-month-old infants and hand-hand behavior in 2-4-month-olds. The increased postural control promoted the emergence of hand-hand behavior when in supine, and decreased hand-mouth behavior when in prone. The results show that self-exploratory behaviors may be affected not only by extrinsic constraints, represented by different body positions, but also by intrinsic constraints, represented by characteristic action possibilities and postural control of each age group. 相似文献

The aim of the present study is to explore the MCMI-II personality style and MCMI-II possible disorder of borderline personality (BPD) in various groups of women. 93 patients-31 anorexia nervosa restricting subtype (ANr), 31 anorexia nervosa binge-eating/purging subtype (ANp), and 31 bulimia nervosa purging subtype (BNp); 31 women at high risk for eating disorder or symptomatic control group (S-CG) and 31 without known pathology or not symptomatic control group (NS-CG)-completed the Spanish version of the MCMI-II. The results revealed: (1) clinically significant borderline personality traits [74>Base Rate (BR) <85]: 16.1% ANr, 12.9% ANp, and 45.2% BNp versus 3.2% of the S-CG and none of the NS-CG; (2) possible disorder (BR>84): 29% ANr, 41.9% ANp and 29% BNp. According to the MCM-II, women with BNp displayed more BPD traits than possible disorder (though these were more severe). However, the probability of a possible disorder was higher in ANp (more disorders than traits). 相似文献
