The main purpose of this study was to investigate the relationship between adolescent computer use and academic achievement. Questionnaires and seven-day time logs were used to gather data from 101 tenth-grade students in southwestern Ohio. The adolescents both estimated and documented their computer use. The correlation between computer use and grade point average was not found to be significant. However, gender differences were found across grade point average and time spent doing homework on and off the computer. Estimates of time spent per week using the computer were correlated with the time recorded in logs. 相似文献

Pitch perception is fundamental to melody in music and prosody in speech. Unlike many animals, the vast majority of human adults store melodic information primarily in terms of relative not absolute pitch, and readily recognize a melody whether rendered in a high or a low pitch range. We show that at 6 months infants are also primarily relative pitch processors. Infants familiarized with a melody for 7 days preferred, on the eighth day, to listen to a novel melody in comparison to the familiarized one, regardless of whether the melodies at test were presented at the same pitch as during familiarization or transposed up or down by a perfect fifth (7/12th of an octave) or a tritone (1/2 octave). On the other hand, infants showed no preference for a transposed over original-pitch version of the familiarized melody, indicating that either they did not remember the absolute pitch, or it was not as salient to them as the relative pitch. 相似文献

The authors examined the longitudinal association between externalizing and depressive symptoms using a sample of 185 young adolescents whose mothers had histories of depression. The relation between externalizing behaviors in 6th grade and depressive symptoms a year later was partially mediated by dependent social stressors. Moreover, consistent with the personality-event congruence hypothesis, this mediation model was particularly true for children with high levels of interpersonal orientation (Neediness and Connectedness). In contrast, social stressors that were judged to be independent of the children's behavior, as well as both dependent and independent nonsocial stressors, did not mediate the longitudinal relation between externalizing and depressive symptoms. 相似文献

Mel Gibsons film, The Passion of the Christ, has elicited great response, both positive and negative. The purpose of this article is to explore one controversial aspect of the movie, anti-Judaism. After addressing problems inherent in the term, anti-Judaism, the article highlights elements of the New Testament gospels that have been interpreted as anti-Jewish, offers an analysis of Gibsons interpretation of the role of the Jews in the death of Jesus, and closes with a discussion of the implications of Gibsons presentation of the Jews on contemporary Jewish/Christian relations. 相似文献

The triadic match is the author's term for the interaction among analytic candidate, supervisor, and patient. Overlapping or diverging characteristics of candidate and supervisor may influence the candidate's learning for good or ill depending on the way patient's and candidate's character and conflicts interact. Four candidates who had found their supervisors' character and supervisory styles particularly beneficial in relation to a particular patient volunteered to describe their experiences. Candidates and supervisors were interviewed. The aim of the paper is to illuminate factors in the match that enhanced or interfered with the candidates' learning. While the paper is presented from the perspective of the candidates' experiences, the balance between challenge and comfort in learning situations is also considered. 相似文献

This study assessed the association between aspects of mother's employment and security of infant-mother attachment, in combination with proximal (maternal sensitivity) and distal (demographic, maternal, child, child-care) factors. Participants were 145 Australian mothers and their firstborn children. Attachment security was assessed with the Strange Situation at 12 months. Results showed that mothers' prenatal attitudes to work and timing of the return to work made significant, independent contributions to attachment outcomes over and above the effects of proximal and distal predictors. Mothers who expressed more commitment to work and less anxiety about using nonfamily child care, and who returned to work earlier, were more likely to have secure infants. These findings are considered in relation to contemporary expectations about mothers' participation in paid work and other predictors of secure attachment. 相似文献

Electrocortical evidence indicates that a wave of synaptic proliferation occurs in the frontal lobes around the age of puberty onset. To study its potential influence on cognition, we examined 246 children (10-17 years) and 49 young adults (18-22 years) using a match-to-sample type of task to measure reaction times to assess emotionally related information. Based upon the instruction set, subjects made a yes/no decision about the emotion expressed in a face, a word, or a face/word combination presented tachistoscopically for 100 ms. The faces were images of a single individual with a happy, angry, sad or neutral expression. The words were 'happy,' 'angry,' 'sad,' or 'neutral,' In the combined stimulus condition, subjects were asked to decide if the face and word matched for the same emotion. Results showed that compared to the previous year, reaction times were significantly slower for making a correct decision at 11 and 12 years of age in girls and boys, the approximate ages of puberty onset. The peripubertal rise in reaction time declined slowly over the following 2-3 years and stabilized by 15 years of age. Analyses of the performance of 15-17 year olds revealed significantly longer reaction times in females to process both faces and words compared to males. However, this sex difference in late puberty appeared to be transient since it was not present in 18-22 year olds. Given the match-to-sample nature of the task employed, the puberty related increases in reaction time may reflect a relative inefficiency in frontal circuitry prior to the pruning of excess synaptic contacts. 相似文献

The vision for the special issue in Brain and Cognition is rooted in the need to bring to the foreground the state of scientific knowledge in research and clinical neuroimaging ethics. To this end, the issue highlights a broad range of relatively unexplored ethical challenges in functional neuroimaging with MR, alone or in combination with other neuroimaging modalities, from imaging the central nervous system of the fetus in utero through neural activation patterns associated with cognition and behavior in childhood and in adulthood. Theoretical, practical, and ethical considerations at the heart of imaging healthy research subjects and cognitively compromised patients are explored. 相似文献

Interest in genetic testing for inherited cancer susceptibility is high in the general population. Women at risk for BRCA1 and BRCA2 mutations represent the best-studied population undergoing genetic testing for cancer susceptibility. However, it is unclear whether factors influencing interest in genetic testing in women are directly applicable to men. We designed a study to examine factors associated with men's interest in genetic testing to identify prostate cancer susceptibility. Our sample consisted of 267 men present in waiting rooms of a urology clinic in an urban area. We examined whether the concept of monitoring could be used to predict the interest of men in a genetic test for prostate cancer susceptibility. Our results indicated that monitoring trait was positively associated with interest in genetic testing in these men, but principally for patients rather than nonpatients. Moreover we found that monitoring was associated with over estimation of risk in those men with prostate cancer. Other factors found to influence interest in genetic testing included recommendation by a doctor, family history of prostate cancer, and cost. This study indicated that interest in genetic testing and estimation of risk is influenced by a complex interaction between both psychological factors (monitoring) and nonbehavioral factors (such as patient status, cost, and doctor recommendation). 相似文献
