A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions
remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading
development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to
differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech
stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures
of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years.
Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal
maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1
amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient
in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal
recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related
to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech
stimuli. The early development of biologically based differences in the perception and processing of auditory information
contributes to later group differences in reading proficiencies at school age. 相似文献

Fifteen children with anogenital warts are presented. Twelve cases were referred for assessment of sexual abuse which was established in six cases, strongly suspected in one, and excluded in three. In two, the source was unclear. Papillomavirus typing was carried out by HPV DNA dot and Southern blot hybridization using mixed HPV 6/11, 16/18, and 2/3 DNA probes on 15 specimens from 12 of the children. Seven biopsy specimens were positive for HPV 6 or 11 and one hybridized with both HPV 6/11 and 16/18 mixed sets of probes. Two specimens were positive for HPV 2, and a further two hybridized with both HPV 18 and 2. Three wart specimens could not be typed with the available genital or skin probes. The viruses causing genital tract papillomata are the same for children and adults. The identification of HPV 16/18 raises the concern of potential oncogenicity and stresses the need for long-term assessment. The diagnosis of sexual abuse was made on history rather than examination, as only two cases showed additional physical signs of sexual abuse. It is advocated that the presence of anogenital warts alone be sufficient grounds to pursue the possibility of sexual abuse. Nonsexual transmission, although possible, is far less likely. 相似文献

Congruence between Mothers' and Fathers' Differential Treatment of Siblings: Links with Family Relations and Children's Well-Being 总被引:2,自引:1,他引:2

We studied patterns of mothers' and fathers' differential treatment of firstborn (average age 10.5 years) and secondborn (average age 8 years) school-age siblings, and we examined the links between parents' differential treatment and children's well-being and dyadic family relationships. Mothers, fathers, and both siblings in 110 families were interviewed in their homes. For each dimension of parental behavior that we assessed (i.e., differential affection and discipline) we created groups of families that reflected mothers' and fathers' levels of differential treatment (e.g., discipline the firstborn more, equal treatment, discipline the secondborn more). Although we detected substantial correspondence between the 2 parents' differential treatment, we found a sizable group of families in which parents' reports were incongruent (i.e., 1 parent reported equal and the other differential treatment). Parental patterns were linked to differences between the siblings' well-being and both sibling and parent-child relationships, with younger siblings exhibiting greater vulnerability to differential treatment. Incongruence in differential warmth was associated with marital distress. 相似文献

Many ideas in the biological sciences seem especially difficult to understand, learn, and teach successfully. Our goal in this feature is to explore how these difficulties may stem not from the complexity or opacity of the concepts themselves, but from the fact that they may clash with informal, intuitive, and deeply held ways of understanding the world that have been studied for decades by psychologists. We give a brief overview of the field of developmental cognitive psychology. Then, in each of the following sections, we present a number of common challenges faced by students in the biological sciences. These may be in the form of misconceptions, biases, or simply concepts that are difficult to learn and teach, and they occur at all levels of biological analysis (molecular, cellular, organismal, population, and ecosystem). We then introduce the notion of a cognitive construal and discuss specific examples of how these cognitive principles may explain what makes some misconceptions so alluring and some biological concepts so challenging for undergraduates. We will argue that seemingly unrelated misconceptions may have common origins in a single underlying cognitive construal. These ideas emerge from our own ongoing cross-disciplinary conversation, and we think that expanding this conversation to include other biological scientists and educators, as well as other cognitive scientists, could have significant utility in improving biology teaching and learning. 相似文献

The development of response inhibition was investigated using a computerized go/no‐go task, in a lagged sequential design where 376 preschool children were assessed repeatedly between 3.0 and 5.25 years of age. Growth curve modeling was used to examine change in performance and predictors of individual differences. The most pronounced change was observed between 3 and 3.75 years. Better working memory and general cognitive ability were related to more accurate performance at all ages, but relations with speed changed with age, where better cognitive skills were initially related to slower responding, but faster responding at later ages. Boys responded more quickly and were more accurate on go trials, whereas girls were better able to withhold responding on no‐go trials. 相似文献

Nonstandard grammatical forms are often present in the writing of deaf students that are rarely, if ever, seen in the writing of hearing students. With the implementation of Strategic and Interactive Writing Instruction (SIWI) in previous studies, students have demonstrated significant gains in high-level writing skills (e.g., text structure) but have also made gains with English grammar skills. This 1-year study expands on prior research by longitudinally examining the written language growth (i.e., writing length, sentence complexity, sentence awareness, and function words) of 29 deaf middle-school students. A repeated-measures analysis of variance with a between-subjects variable for literacy achievement level was used to examine gains over time and the intervention's efficacy when used with students of various literacy levels. Students, whether high or low achieving, demonstrated statistically significant gains with writing length, sentence complexity, and sentence awareness. Subordinate clauses were found to be an area of difficulty, and follow up strategies are suggested. An analysis of function word data, specifically prepositions and articles, revealed different patterns of written language growth by language group (e.g., American Sign Language users, oral students, users of English-based sign). 相似文献

Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, and intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory, inhibitory control, cognitive flexibility). A group of 5‐month‐olds (n = 201) were classified as short or long lookers. At 24, 36, and 48 months of age, children completed age‐appropriate EF tasks. Infant short lookers (i.e., more efficient information processors) exhibited higher EF throughout early childhood as compared to infant long lookers, even after controlling for verbal ability (a potential indicator of intelligence). These findings are discussed in relation to the emergence of executive attention. 相似文献

Rebecca Rogers 《Paedagogica Historica: International Journal of the History of Education》2014,50(6):717-736
This article considers the role Paedagogica Historica has played in stimulating new approaches in the history of education within the international community since the emergence of the new series in 1900. Particular focus is placed on the volumes published in the wake of ISCHE (International Standing Conference in the History of Education) conferences and the special issues, which the editors began to promote in 1990 as a way of highlighting innovative scholarship in the field. The article considers a total of 55 issues. In addition to a presentation of the diversity of topics addressed, the article assesses the following: editorial strategies to reach a broader public and connect with specialised networks internationally; efforts to achieve international ranking for the journal; the ways individual scholars or national communities showcase certain approaches or themes in the history of education. Finally, the article will consider the limits to the journal’s efforts to establish trends in our contemporary digital age. 相似文献
