Academic achievement is crucial for life and long-term outcomes. The aim of the present study is to examine the joint role of cognitive (intelligence and working memory) and non-cognitive (academic self-esteem) factors in predicting academic achievement (mathematics and reading literacy) in a sample of Italian sixth and eighth graders. The results showed that within the cognitive factors considered, intelligence was the best predictor of achievement. As regards to non-cognitive factors, academic self-esteem was effective at predicting achievement after controlling for cognitive measures. Academic self-esteem was also found to have an indirect effect, mediated by intelligence, on academic achievement. Both theoretical and practical implications of the present results are discussed.  相似文献

Rigorous research and program evaluation are needed to understand the experience of dating and sexual violence among youth and the impact of prevention and intervention efforts. Our dilemma in doing this work occurred when youth disclosed dating and sexual violence on a research survey. What responsibility do researchers have to protect survivors’ confidentiality as a research participant versus taking steps to ensure the student has the opportunity to access help? In our evaluation of a pilot dating violence prevention program, our protocols employed widely used procedures for providing resources to participants upon their completion of the survey and de‐identifying survey data. Upon reviewing preliminary survey results, we became concerned that these established procedures were not sufficient to support research participants who were adolescent survivors of dating and sexual violence. We followed a structured ethical decision‐making process to examine legal and ethical considerations, consult with colleagues, consider impacts and alternative solutions, and ultimately find a solution. Through this process, we developed procedures that balance participant confidentiality and the desire to support the welfare of survivors, which other researchers may want to employ when conducting youth sexual and dating violence research in school and community settings.  相似文献

To understand how socioeconomic status (SES) and bilingualism simultaneously operate on cognitive and sensory function, we examined executive control, language skills, and neural processing of sound in adolescents who differed in language experience (i.e. English monolingual or Spanish‐English bilingual) and level of maternal education (a proxy for SES). We hypothesized that experience communicating in two languages provides an enriched linguistic environment that can bolster neural precision in subcortical auditory processing which, in turn, enhances cognitive and linguistic function, regardless of the adolescent's socioeconomic standing. Consistent with this, we report that adolescent bilinguals of both low and high SES demonstrate more stable neural responses, stronger phonemic decoding skills, and heightened executive control, relative to their monolingual peers. These results support the argument that bilingualism can bolster cognitive and neural function in low‐SES children and suggest that strengthened neural response consistency provides a biological mechanism through which these enhancements occur.  相似文献

We question the validity of traditional polling about the likelihood of respondents to vote for a woman president and argue that the use of such polls may overestimate sexism and underestimate the role that party identification and individual characteristics play in deciding about whether to vote for a woman president. Our analysis of data collected in May–June 2004 show that many people who say they will not vote for a woman for president would do so if given realistic, specific, political scenarios via head-to-head match-ups with potential candidates. Although survey respondents preferred George W. Bush to Hillary Clinton, the margin between these candidates was close especially considering that Bush had been actively campaigning for months, whereas Clinton had not.  相似文献

This study sought to discover if an optimum 1 cm2 area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in eight aphasia cases. Picture naming and response time (RT) were examined before, and immediately after rTMS. In aphasia patients, suppression of right pars triangularis (PTr) led to significant increase in pictures named, and significant decrease in RT. Suppression of right pars opercularis (POp), however, led to significant increase in RT, but no change in number of pictures named. Eight normals named all pictures correctly; similar to aphasia patients, RT significantly decreased following rTMS to suppress right PTr, versus right POp. Differential effects following suppression of right PTr versus right POp suggest different functional roles for these regions.  相似文献

This study used a new cell phone ecological momentary assessment approach to investigate daily emotional dynamics in 47 youths with major depressive disorder (MDD) and 32 no-psychopathology controls (CON) (ages 7-17 years). Information about emotional experience in the natural environment was obtained using answer-only cell phones, while MDD youths received an 8-week course of cognitive behavioral therapy and/or psychopharmacological treatment. Compared with CON youths, MDD youths reported more intense and labile global negative affect; greater sadness, anger, and nervousness; and a lower ratio of positive to negative affect. These differences increased with pubertal maturation. MDD youths spent more time alone and less time with their families than CON youths. Although differences in emotional experiences were found across social contexts, MDD youths were more negative than CON youths in all contexts examined. As the MDD participants progressed through treatment, diagnostic group differences in the intensity and lability of negative affect decreased, but there were no changes in the ratio of positive to negative affect or in measures of social context. We discuss methodological innovations and advantages of this approach, including improved ecological validity and access to information about variability in emotions, change in emotions over time, the balance of positive and negative emotions, and the social context of emotional experience.  相似文献

The relation of phonological memory to language experience and development was investigated in 41 Spanish-English bilingual first language learners. The children’s relative exposure to English and Spanish and their phonological memory for English- and Spanish-like nonwords were assessed at 22 months of age, and their productive vocabulary and grammar in both languages were assessed at 25 months of age. Phonological memory for English-like nonwords was highly correlated with that for Spanish-like nonwords, and each was related to vocabulary and grammar in both languages, suggesting a language-general component to phonological memory skill. In addition, there was evidence of language-specific benefits of language exposure to phonological memory skill and of language-specific benefits of phonological memory skill to language development.  相似文献

This study investigated the effectiveness of using special training machines for children with intellectual disabilities to strengthen their body's inner muscles and improve their ability to maintain standing posture and improve walking movement. The participants were 23 high school age boys with intellectual disabilities who had difficulties expressing greetings, and needed to be led by the hand when walking. Four special training machines were used for walking movements, for standing and walking balance, for leg-hip extension, and for ipsilateral movement in a sitting position. Each participant underwent 30 min. of training once a week over a 3-mo. period during school time. Body control ability required to perform each training exercise was improved over the training period. A significant improvement was observed in the 50-m dash, mean 10-m walk time, and 10-m obstacle course walk. The hip joint split angle showed a significant increase. Legal guardians all reported their child had "improved and/or progressed" for each of the targeted movements.  相似文献

Do narcissists have insight into the negative aspects of their personality and reputation? Using both clinical and subclinical measures of narcissism, the authors examined others' perceptions, self-perceptions, and meta-perceptions of narcissists across a wide range of traits for a new acquaintance and close other (Study 1), longitudinally with a group of new acquaintances (Study 2), and among coworkers (Study 3). Results bring 3 surprising conclusions about narcissists: (a) they understand that others see them less positively than they see themselves (i.e., their meta-perceptions are less biased than are their self-perceptions), (b) they have some insight into the fact that they make positive first impressions that deteriorate over time, and (c) they have insight into their narcissistic personality (e.g., they describe themselves as arrogant). These findings shed light on some of the psychological mechanisms underlying narcissism.  相似文献

The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".  相似文献
