In this article we consider the difficulties of children who have a specific reading comprehension problem. Our earlier work has shown that good and poor comprehenders differ, in particular, in their ability to make inferences, integrate information in text, understand story structure, and monitor their understanding. We outline some studies that illustrate the poor comprehenders' problems and present two studies that use a comprehension-age match design to explore the direction of causality between comprehension skill and other abilities. We also present data from the first and second stages of a longitudinal study, when the children were 7 to 8 and 8 to 9 years old. Multiple regression analyses show that a number of factors predict significant variance in comprehension skill even after "general ability" factors such as IQ and vocabulary have been taken into account. These findings suggest that, not only can children have comprehension problems in the absence of word recognition problems, but that distinctly different skills predict variance in word recognition and variance in comprehension. The data support the view that single-word reading skills and the ability to build integrated text representations make independent contributions to overall reading ability. We discuss the implications of these findings for our understanding of children's problems in text comprehension, for deaf readers, and for remediation. 相似文献

Do infants see emotional expressions in static faces? 总被引:2,自引:0,他引:2
To determine whether young infants discriminate photographs of different emotions on an affect-relevant basis or on the basis of isolated features unrelated to emotion, groups of 17-, 23-, and 29-week-olds were habituated to slides of 8 women posing either Toothy Angry, Nontoothy Angry, or Nontoothy Smiling facial expressions and were then shown 2 new women in the familiarized expression and in a novel Toothy Smiling expression. At all 3 ages, recovery to the novel Toothy Smiling faces occurred only after habituation to Nontoothy faces (whether smiling or angry), not after habituation to Toothy Angry faces, indicating that infants had been responsive to nonspecific features of the photographs (presence or absence of bared teeth) rather than to affectively relevant configurations of features. In a second experiment, 2 older age groups (35 and 41 weeks) also proved to be insensitive to affect-related aspects of still faces, though more so for angry than for happy expressions. It is suggested that the young infant's difficulty in extracting emotional information from static stimuli may be attributable to the absence of the critical invariants (dynamic, multimodally specified) that characterize naturalistic expressions of emotion. 相似文献

The purpose of this study was to quantify social interaction rhythms in 3- and 5-month-old term and preterm infants and their mothers. Infant-mother dyads were videotaped in a 3-min face-to-face paradigm. For each second of the interaction, separate scores were assigned to infant and mother indicating levels of affective involvement, creating 2 180-sec time series. Spectral and cross-spectral techniques were used to quantify periodicities in each member of the dyad and to estimate the synchrony or coherence of interactional rhythms between each infant and mother. Results showed the existence of periodicities in the behavior of each infant and mother at 3 and 5 months, with most subjects showing spectral peaks between .022 and .10 Hz. Increases from 3 to 5 months in behavioral periodicities were found for infants and mothers as well as for the coherence between infant-mother dyads. Term dyads showed higher coherence than preterm dyads at both 3 and 5 months. Term infants more often led the interaction at both ages. These results were taken as evidence that behavioral periodicities, which may be biologically based, underlie early mother-infant interaction and provide a temporal structure for the organization of cognitive and affective experience. Differences in synchrony between term and preterm infants may explain later reported differences in language between these groups. 相似文献

The present paper examines whether there is significant variation in schooling outcomes between Scottish secondary schools, and if so, how much is associated with pupil intake, and how much is associated with the schools they attend. It also examines whether schools vary in their effectiveness for different types of pupils, and whether schools tend to be superior, or inferior, across three different outcome measures. The study employed a subsample of data from the 1977 Scottish School Leavers Survey on over 700 pupils from 15 schools in one administrative division. These data were linked to data on the verbal reasoning quotients of the pupils, derived from a test administered to them before they entered secondary school. For each of the 15 schools we estimated the expected scores on measures of English, arithmetic and overall attainment for pupils with below average, average, and above average ability, controlling for pupils’ verbal ability, gender, prestige of father's occupation, mother's education, and number of siblings. The study shows there was wide variation in schooling outcomes between secondary schools in the division, even after controlling for family background characteristics and pupil ability prior to entering secondary school. There were few schools that were particularly effective for low ability pupils, but not high ability pupils and vice versa. Schools tended to be effective, or ineffective, across all three outcome measures. 相似文献

The study was designed to investigate the influence of student characteristics and classroom characteristics on students' inquiry skill. The sample consisted of a national stratified random sample of 1955 17-year-olds who were assessed as part of the 1981-1982 national assessment in science. The dependent variable was a 17-item measure of students' inquiry skill. The independent variables were selected from the available data using the Model of Educational Productivity as a guide in the selection of the variables. The first purpose of the study was to test the effectiveness of the Model of Educational Productivity for predicting the inquiry skill of 17-year-olds. The results of this study indicate that this model was capable of accounting for between 24 and 32% of the variance in inquiry skill for the general population of 17-year-olds. More specifically, students' reporting of their general ability alone accounted for between 17 and 22% of the variance. The second question posed by this study asked whether the prediction of inquiry skill differed for males and females. While there was some difference in the contribution of the minor predictors, there was very little difference in the prediction of inquiry skill for males and females using the Model of Education Productivity. The third question posed by this study asked whether the prediction of inquiry skill differed for white and nonwhite students. For nonwhite students, the Model of Educational Productivity accounted for only 18% of the variance in science inquiry skill. Thus, it would appear that there is a great deal that is not known about the factors that contribute to the science inquiry skill of nonwhite students. 相似文献

One hundred eighty-one experienced teachers (elementary and junior high), and 189 preservice teachers were surveyed regarding their perceptions of school psychologists. The survey instrument used essentially the same categories as Styles in 1965, including: (a) level of training, (b) effectiveness, (c) qualifications for tasks, and (d) usefulness in specific duties. Analysis of the survey data showed there were significant differences between preservice and experienced teachers' effectiveness ratings of school psychologists on eight tasks typically performed by school psychologists. Significant differences also were found between preservice and experienced teachers on their ratings of school psychologists' qualifications to undertake specific tasks, although almost half of the experienced teachers were unable to rate the effectiveness of school psychologists. There was a small, but significant, negative relationship between the amount of contact with the school psychologist and the perceived effectiveness. Limitations inherent in survey methodology and the need to foster greater teacher awareness of the school psychologist's role are discussed. 相似文献
