In three experiments, the distribution and malleability of infant visual attention were studied in 5-month-olds (N = 72) while they inspected large geometric designs. In Experiment 1, we established that infants maintained their distribution of attention from a pretest to a familiarization phase. We also replicated and extended our previous findings that infants who examined targets with briefer, more numerous looks and shifts-short lookers-had novelty scores above chance, whereas long lookers demonstrated chance responding. In Experiment 2, different portions of the display were successively illuminated with red light. This manipulation induced long lookers to scan like short lookers during familiarization; they then showed novelty scores well above chance. A third experiment ruled out the simple presence of a red light as the source of this effect. In sum, then, these results suggest that the distribution of attention is malleable, and that a broader distribution of attention, as reflected in briefer and more numerous looks and shifts, can improve processing.  相似文献

This study examined the peer nominations of 213 children in Kindergarten (90), 3rd grade (58), and 5th grade (65) to examine their perceptions of peers who received pull-out services for unique needs. Using Coie, Dodge, and Coppotelli’s[1982. “Dimensions and Types of Social Status: A Cross-age Perspective.” Developmental Psychology 18 (4): 557–570] protocol for assessing sociometric status in children, the results revealed that peer perceptions of most liked (ML) and least liked (LL) in the classroom were associated with pull-out status, with those students who did not receive pull-out services receiving more nominations as ML than their peers who did leave the classroom for pull-out services. Social impact scores for children who received pull-out services were not significantly different from those of children who did not receive pull-out services, but significant differences were revealed for social preference scores. Implications and avenues for future research are discussed.  相似文献

This study investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Infants were given trials in which they viewed a shape for either 10-, 15-, 20-, or 30-sec familiarization and were then tested for visual recognition memory using the paired comparison technique. While the older infants showed evidence of recognition memory after less familiarization time than the younger ones, at both ages preterms required considerably longer familiarization than full-terms. The pattern of performance replicates our earlier finding of developmental lags in the visual information processing of 6-month-old preterms and extends these findings to 12-month-olds. These results suggest that there are persistent differences between preterm and full-term infants throughout at least the first year of life in this very fundamental aspect of cognition.  相似文献

The number of supplementary schools in England serving minority communities continues to grow. They are popular with the parents of such communities because they often feel their children are disadvantaged in mainstream schools and not afforded the opportunities or the learning environment that is conducive to their children achieving their full potential. Simultaneously, over the past 10 years or so there has been an increasing political focus on local communities and issues of cohesion; both of which were high priorities for the last government. Schools were viewed as key to helping the government deliver these political agendas. The current coalition government also foregrounds the role and responsibilities of communities as part of its ‘Big Society’ concept. This paper explores the positioning of supplementary schools in relation to notions of ‘cohesive communities’. It draws on findings from a study commissioned by the Department for Children, Schools and Families on supplementary schools, which aimed to establish their level and type of provision, impact, and to a lesser degree, their role in the community and the cohesion agenda.  相似文献

Hiring employees with advanced education, training, and experience has been a prevalent human resource practice in dynamic science-based industries, and a growing body of literature has demonstrated the importance of scientists in such fields. Little research has attempted to distinguish the functional from the symbolic roles of scientists, however. We develop an integrative theoretical framework to separate the productive and legitimating effects of scientists on strategic alliance formation of firms. Results from a longitudinal analysis of more than 300 U.S. biotechnology firms between 1988 and 1999 suggest a positive relationship between ratio of scientists and R&D alliance partners as well as a positive relationship with finance alliance partners. Scientists influence partner attraction more strongly for firms that are less-well-connected, and they become less prominent in fostering finance ties as the industry practice of partnership becomes more institutionalized. We conclude that scientists serve more than just a research function in knowledge-intensive industries. Implications for building interorganizational networks and managing human resources in such industries are discussed.  相似文献

The present study investigated the persistent nature of naming speed deficits within the context of the double-deficit hypothesis in a university sample of adults with reading disabilities (RD). Twenty-five university students with RD were compared to 28 typically achieving readers on measures of reading skill, phonological processing, and naming speed. The results indicated that both naming speed and phonological processing deficits characterized the RD group. In a regression analysis, neither naming speed nor phonological processing were important variables in explaining comprehension when reading rate was in the model. The results of the present study are mixed at best and are consistent with earlier conclusions that support for the double-deficit hypothesis of dyslexia remains limited.  相似文献

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.  相似文献

The aim of the present study was to investigate teachers’ sickness presenteeism (SP). We examined the prevalence of SP in a sample of teachers as well as work-related and health-related influencing factors of teachers’ SP. We used a cross-sectional study design. Teachers working at different types of schools in Rhineland-Palatinate (Germany) participated in an online survey. We used Pearson’s Chi-squared test (in case of categorical variables) or Mann–Whitney-U-test (in case of continuous variables) to test for differences between SP and sociodemographic/work-related/health-related factors. Factors influencing SP were identified using multivariable logistic regression analyses. Nine hundred and twenty-four teachers working at 42 different schools completed the questionnaire (response proportion: 50.1%). The prevalence of SP in our study was 57.1%. The multivariable logistic regression analyses showed less support by supervisors (aOR: 1.77; 95-CI: 1.21–2.60), inappropriate administration efforts (aOR: 1.56; 95-CI: 1.16–2.11), and inappropriate recognition of performance (aOR: 1.44; 95-CI: 1.04–198) as well as exhaustion/fatigue (aOR: 2.29; 95-CI: 1.71–3.08) as main predictors of teachers’ SP. SP is widespread among teachers. As SP is associated with impairment of psychological and physical health in the long run, it is important to implement measures to reduce SP. A climate of support and cooperation as well as assistance for ill teachers to deal with work missed due to absence might be useful strategies.  相似文献
