Two experiments assess the effect of the amount of physical detail in pictures on picture recognition memory. Children and adults were presented simple and complex line drawings. A “same-different” recognition test followed in which the distractor items were original pictures from the presentation phase with the amount of physical detail altered. For second- and fourth-grade subjects, recognition sensitivity, measured in terms of d′, was similar for pictures in the simple and complex presentation conditions. For adults, however, recognition sensitivity was greater for pictures in the simple than complex presentation condition. This finding with adults was replicated in Experiment 2. Interpretations of this age difference in picture memory processing are discussed, as well as the constraints imposed by various dependent measures used in picture memory studies. 相似文献

Two symbol-naming experiments were conducted assessing the dependence of Fitts and Switzer's set-familiarity effect upon symbol distinctiveness. Sixty college males named printed letters presented in a strobotron tachistoscope, the letter always being selected from a preannounced set of three. A voice key detected the response. Experiment I found the Fitts and Switzer finding to be a joint effect: response latency for naming the symbol B in the unfamiliar but distinctive set, VBO, was intermediate to that for the familiar distinctive set, ABC, and the unfamiliar, homolographic set, PBE, the two sets used by Fitts and Switzer. Experiment II, a factorial combination of set familiarity and symbol distinctiveness yielded a significant interaction such that with homolographic symbols, set familiarity was associated with an increase in reaction time. The results were interpreted as consistent with an hypothesis that the set-familiarity effect relates to symbol-identification time as opposed to response-identification time. 相似文献

This study asked whether the reading behavior of dyslexics differs qualitatively from that of normal children. Thirty-seven children who had been identified is dyslexic (mean age 11 years, 9 months) were matched with 37 normal readers (mean age 8,6) on ability to read regular words. The dyslexics' and normals' levels of performance on nonsense words and exception words were strikingly close. Also, patterns of individual differences were similar for the two groups. The results suggest that these dyslexics are delayed in the development of both spelling-sound rules and word specific associations. They do not support the view that dyslexics have a specific deficit in the use of spelling-sound rules, or that dyslexics show more extreme individual differences than do normal readers. 相似文献

Using birth stories as our object of inquiry, this article examines the ways in which normative discourses about gender, disability and Down syndrome construct the birth stories of three mothers of children with Down syndrome. Their stories are composed of the mothers’ recollections of the first hours after birth as a time when their infants are separated from them and their postpartum needs are ignored. Together, their stories illustrate socio-cultural tropes that position Down syndrome as a dangerous form of the “other” and mothers who give birth to children with Down syndrome as implicated in transgressing cultural norms. 相似文献

Observers perceive objects in the world as stable over space and time, even though the visual experience of those objects is often discontinuous and distorted due to masking, occlusion, camouflage, or noise. How are we able to easily and quickly achieve stable perception in spite of this constantly changing visual input? It was previously shown that observers experience serial dependence in the perception of features and objects, an effect that extends up to 15 seconds back in time. Here, we asked whether the visual system utilizes an object’s prior physical location to inform future position assignments in order to maximize location stability of an object over time. To test this, we presented subjects with small targets at random angular locations relative to central fixation in the peripheral visual field. Subjects reported the perceived location of the target on each trial by adjusting a cursor’s position to match its location. Subjects made consistent errors when reporting the perceived position of the target on the current trial, mislocalizing it toward the position of the target in the preceding two trials (Experiment 1). This pull in position perception occurred even when a response was not required on the previous trial (Experiment 2). In addition, we show that serial dependence in perceived position occurs immediately after stimulus presentation, and it is a fast stabilization mechanism that does not require a delay (Experiment 3). This indicates that serial dependence occurs for position representations and facilitates the stable perception of objects in space. Taken together with previous work, our results show that serial dependence occurs at many stages of visual processing, from initial position assignment to object categorization. 相似文献

Background . Low levels of literacy and high levels of behaviour problems in middle childhood often co‐occur. These persistent difficulties pose a risk to academic and social development, leading to social exclusion in adulthood. Although parent‐training programmes have been shown to be effective in enabling parents to support their children's development, very few parent interventions offer a combination of behavioural and literacy training. Aims . This paper (1) reports on a prevention programme which aimed to tackle behaviour and literacy problems in children at the beginning of school, and (2) presents the effects of the intervention on children's literacy. Sample . One hundred and four 5‐ and 6‐year‐old children selected from eight schools in an inner city disadvantaged community in London participated in the intervention. Methods . This is a randomized control trial with pre‐ and post‐measurements designed to evaluate the effectiveness of an intervention. The behavioural intervention consisted of the ‘Incredible Years’ group parenting programme combined with a new programme designed to train parents to support their children's reading at home. Results . Analyses demonstrated a significant effect of the intervention on children's word reading and writing skills, as well as parents' use of reading strategies with their children. Conclusion . A structured multicomponent preventive package delivered with attention to fidelity can enable parents to support their children's reading at home and increase their literacy skills. Together with the improvement in child behaviour, these changes could improve the life chances of children in disadvantaged communities. 相似文献

We present baseline data and describe the utility of a community engaged, culturally relevant approach to recruiting African
American youth and families for phase I of The AAKOMA Project. The AAKOMA Project is a two phase treatment development study
to improve mental health service use among depressed African American youth. We completed capacity building activities using
a community engaged framework and Community Based Participatory Research (CBPR) methods. Replicating the (Alvarez et al. in
West J Nurs Res 28:541–560, 2006) model of systematic community outreach enhanced our ability to effectively recruit partners and evaluate outreach efforts
as demonstrated by our Recruitment Success Factor (RSF—i.e. ‘an adjusted ratio of eligible participant yield to contacts made’).
Using the chi-square goodness-of-fit statistic; we compared the RSFs of the various modes of participant study entry to determine
which was most effective. Our target enrollment was 56 persons. We recruited 130 and enrolled 57. Our baseline data is drawn
from a gender balanced and socioeconomically diverse sample who participated in youth focus groups and individual interviews
and adult focus groups. We identified 3 study participant referral modes (self-referral, provider referral and participant-to-participant
referral) with multiple sources per mode and an overall RSF of 0.41. Study findings support the effectiveness of assiduous
and systematic community interaction, reflective review of recruitment efforts and the importance of disseminating information
on strategic recruitment processes for engaging diverse populations in clinical research. 相似文献
