Task experience and children's working memory performance: a perspective from recall timing 总被引:1,自引:0,他引:1
Working memory is an important theoretical construct among children, and measures of its capacity predict a range of cognitive skills and abilities. Data from 9- and 11-year-old children illustrate how a chronometric analysis of recall can complement and elaborate recall accuracy in advancing our understanding of working memory. A reading span task was completed by 130 children, 75 of whom were tested on 2 occasions, with sequence length either increasing or decreasing during test administration. Substantial pauses occur during participants' recall sequences, and they represent consistent performance traits over time, while also varying with recall circumstances and task history. Recall pauses help to predict reading and number skills, alongside as well as separate from levels of recall accuracy. The task demands of working memory change as a function of task experience, with a combination of accuracy and response timing in novel task situations being the strongest predictor of cognitive attainment. 相似文献

The accuracy of female perceivers on a face sex‐categorization task was investigated as a function of perceivers' menstrual cycle and target facial qualities. Regularly ovulating female participants completed a sex‐categorization task twice, once during ovulation (high fertility) and once during menstruation (low fertility). Perceivers made more errors in identifying male than female faces at both testing sessions. Fewer errors were made in identifying male targets rated high on masculinity, but only during periods of high fertility. For female targets accuracy was negatively associated with masculinity and positively associated with attractiveness ratings, at both high and low fertility testing sessions. Results are discussed in terms of adaptive person construal. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Male breast cancer is a serious issue that needs to be addressed more fully by the medical and public community. However,
due to a lack of awareness and limited research on the topic, there is a general absence of knowledge concerning the psychological
implications of this disease in men as well as a need for greater understanding of the medical diagnosis and treatment of
male breast carcinoma. Similarly, there still remains a considerable gender difference between the awareness of female breast
cancer and male breast cancer Although breast cancer in men makes up only 1% of all breast cancers reported in the United
States, it is increasing in incidence. There are approximately 2000 new cases and approximately 450 deaths due to male breast
cancer each year. Breast cancer diagnosis and treatment in men is very similar to that described in women, however, it has
been shown that men are being diagnosed at a later stage of the disease than women. 相似文献

In a recognition memory test, subjects may be asked to decide whether a test item is old or new (item recognition) or to decide among alternative sources from which it might have been drawn for study (source recognition). Confidence-rating-based receiver operating characteristic (ROC) curves for these superficially similar tasks are quite
different, leading to the inference of correspondingly different decision processes. A complete account of source and item
recognition will require a single model that can be fit to the entire data set. We postulated a detection-theoretic decision
space whose dimensions, in the style of Banks (2000), are item strength and the relative strengths of the two sources. A model
that assumes decision boundaries of constant likelihood ratios, source guessing for unrecognized items, and nonoptimal allocation
of attention can account for data from three canonical data sets without assuming any processes specifically devoted to recollection.
Observed and predicted ROCs for one of these data sets are given in the article, and ROCs for the other two may be downloaded
from the Psychonomic Society’s Archive of Norms, Stimuli, and Data, www.psychonomic.org/archive. 相似文献

Williams syndrome (WS) is a genetic disorder associated with severe visuocognitive impairment. Individuals with WS also report difficulties with everyday wayfinding. To study the development of body-, environment-, and object-based spatial frames of reference in WS, we tested 45 children and adults with WS on a search task in which the participant and a spatial array are moved with respect to each other. Although individuals with WS showed a marked delay, like young controls they demonstrated independent, additive use of body- and environment-based frames of reference. Crucially, object-based (intrinsic) representations based on local landmarks within the array were only marginally used even by adults with WS, whereas in typical development these emerge at 5 years. Deficits in landmark use are consistent with wayfinding difficulties in WS, and may also contribute to problems with basic localization, since in typical development landmark-based representations supplement those based on the body and on self-motion. Difficulties with inhibition or mental rotation may be further components in the impaired ability to use the correct reference frame in WS. 相似文献

Successful memory is normally accompanied by explicit awareness of retrieval and confidence in the accuracy of the retrieval product. Prior findings suggest that these features of metamemory can be dissociated from retrieval accuracy in Amnestic Mild Cognitive Impairment (aMCI). However, the literature on this question contains variable and conflicting results, likely because of differences in experimental conditions. We sought to systematically evaluate memory awareness disruptions in aMCI using multiple measures and stimulus formats within the same individuals. Memory awareness was tested with global predictions and postdictions, judgments of learning, confidence level ratings, and modified feeling-of-knowing ratings in tasks of visuospatial and verbal memory. These tests were administered to 14 individuals with aMCI and 15 healthy, age-matched controls. Memory awareness accuracy was calculated as the correspondence between subjective judgments and memory performance.Individuals with aMCI demonstrated impaired global and trial-level retrospective task awareness for visuospatial and verbal stimuli. Additionally, modified feeling-of-knowing awareness was impaired selectively for verbal stimuli. Statistical effect sizes for global awareness impairments were comparable to impairments in several objective neuropsychological memory assessments.Memory awareness (metamemory) disruptions in aMCI were most evident for a subset of subjective judgment types and task input modalities. These findings advance understanding of the nature of memory impairments in aMCI and support the utility of incorporating memory awareness testing to better characterize memory integrity in older adults. 相似文献

Examination of and support for specific practices that promote high-quality home visiting are essential as family support programs continue to expand across the country. The current study used direct observation of 91 home visits across 41 home visitors to examine relations among interaction partners, content of the interactions, the home-visitors’ activities, and quality of home-visitors’ practices and family-members’ engagement within programs funded by the Maternal, Infant, and Early Childhood Home Visiting program. More time spent in triadic interactions focused on child-related content, as measured by the Home Visit Rating Scale-Revised, was related to higher quality of family engagement in home visits, as measured with the Home Visit Observation Rating Scales. Time spent in adult-focused interactions and administrative tasks, however, was related to lower quality of home-visiting practices and family engagement. Implications for research and practice are discussed. 相似文献

The Rational Emotive Behavior Therapy (REBT) concept of frustration intolerance is briefly reviewed and placed in historical
context. It is argued that this concept includes a wide range of belief content, and is best considered as a multidimensional
construct. A multidimensional model is presented, and the implications for theory and practice discussed. 相似文献
