This study compared sentence comprehension skills in typically developing children 5-17 years of age, children with language impairment (LI) and children with focal brain injuries (FL) acquired in the pre/perinatal period. Participants were asked to process sentences 'on-line', choosing the agent in sentences that varied in syntactic complexity (actives, passives, subject clefts and object clefts), and in the presence or absence of a subject-verb agreement contrast. Results revealed that accuracy and processing speeds vary with syntactic complexity in all groups, reflecting the frequency and regularity of sentence types. Developmental changes continued throughout childhood, as children became faster and more accurate at processing more complex sentence structures. Children with LI and children with FL were quite profoundly delayed, displaying profiles similar to, or more impaired than those of younger children, but there was no evidence in the FL group for a disadvantage in left- vs. right-hemisphere-damaged children. Children with LI showed one unique pattern: higher than normal costs (reflected in reaction times) in using converging information from subject-verb agreement, in line with studies suggesting special vulnerabilities in grammatical morphology in this group. Results are discussed in terms of the Competition Model, a theory of language processing designed to account for the statistical changes in performance that are observed during development, and the probabilistic deficits in children with language impairments.  相似文献

What is the time course of human attention in a simple auditory detection task? To investigate this question, we determined the detectability of a 20-msec, 1000-Hz tone presented at expected and unexpected times. Twelve listeners who expected the tone to occur at a specific time after a 300-msec narrowband noise rarely detected signals presented 150-375 msec before or 100-200 msec after that expected time. The shape of this temporal-attention window depended on the expected presentation time of the tone and the temporal markers available in the trials. Further, though expecting the signal to occur in silence, listeners often detected signals presented at unexpected times during the noise. Combined with previous data, these results further clarify the listening strategy humans use when trying to detect an expected sound: Humans seem to listen specifically for that sound, while ignoring the background in which it is presented, around the time when the sound is expected to occur.  相似文献

This study of 456 female and 205 male college students investigated knowledge and attitudes toward infertility and reactions to couples with varied fertility status. The gender and career status of the target individual also were varied. The most negative affect and stories were indicated for those described as childless by choice. The male target character also was rated more negatively than the female target character. The greatest responsibility and control were assigned to childless-by-choice and childless-no-explanation groups. The most positive affect and stories were indicated for those described as childless with no explanation given. Infertile couples were attributed less control and responsibility and elicited some degree of anger and hostility from others.  相似文献

A team of researchers consisting of counselor education professors and doctoral‐level counseling students conducted interviews with Honduran mental health professionals, including counselors, psychologists, pastors, community developmental specialists, and psychiatrists. The purpose was to understand the counseling process and profession that exists in a developing economy. The results are focused on the pervasive effects of poverty on the profession, the training of counselors, and the nature of counseling interventions.  相似文献

Research has supported a negative correlation between cigarette smoking and exercise; however, the temporal nature of this association is not obvious. We modeled the relationships among smoking, exercise, and self-perceived health over time, within a college population. We collected 5 waves of data from 1,023 undergraduate students over a 14-month period. The results verified that smoking and exercise each made independent contributions in the prediction of health. Smoking was associated with reduced exercise over time, while no evidence was found for the reverse relationship. Our final mediation model demonstrates that smoking is related to poorer self-perceived health, and that this effect is partially mediated by the fact that smokers are less likely to engage in exercise.  相似文献

This paper proposes that as the nation move toward the 2020 election, civil harmony might be possible with an ideological shift. Using the words of writer Sylvia Wynter in her work, “ 1492: New World View” who suggest that although this country was structured with domination and subjugation from its inception, this nation could be reimagined to embrace diverse people co-existing. Understanding too that reconciliation must be defined by those who are marginalized, the author using an Afro-futuristic ideology for a 2020 New World Order suggest that the Black Lives Matter movement could carry the torch.  相似文献

The aim of this multimethod, longitudinal study was to examine similarities and differences in aggressive expression and prediction among school-aged boys and girls. The primary research sample involved 174 children (93 females, 81 males). They were in the fourth grade at the beginning of the study, and the fifth grade at its conclusion. Embedded in the primary sample was a subgroup of 20 children identified as being highly aggressive (ten males, ten females), and a subgroup of 20 matched control children. The research measures included teachers' ratings of aggressive behavior, peer-nominations/reports of prior conflicts, individual interviews/self-ratings, and extensive behavioral observations. Analyses of the concurrent relations among measures pointed to a “public” cluster of measures (including peer-nominations, behaviors, and teacher ratings) and relatively “private” measures (ie, subjects' self-evaluations). In the primary sample, significant developmental trends were detected in the teacher ratings with increasing gender differentiation as children grew older. Few gender differences were observed in the high-aggressive subgroup, but the aggressive and the matched control groups differed on virtually all comparisons. Gender differences in predictability were a function of risk status, with high-aggressive girls showing as much stability as high-aggressive boys.  相似文献
