Research in older Caucasians has demonstrated that cognitive activity is related to cognitive function in late adulthood. Knowledge of this association is limited in older minority populations. We examined the relation of cognitive activity and access to cognitive resources, with cognitive function in a group of 108 older African Americans. We constructed two scales to measure the frequency of cognitive activity and the presence of resources that promote cognitive activity during early and late life. Both measures had high internal consistency and the cognitive activity scale had adequate temporal stability over a 4-week interval. In analyses that controlled for age and education, more frequent lifetime cognitive activity was related to current cognitive function, but lifetime cognitive resources only approached significance. The results suggest that both measures are psychometrically sound in a minority population and that lifetime cognitive activity may contribute to current cognitive function in African Americans. 相似文献

Repeated administration of cognitive tests improves test performance, making it difficult for researchers to gauge the true extent of age-related cognitive decline. The authors examined this issue using data from the Rush Religious Orders Study and linear mixed-effects models. At annual intervals for up to 8 years, more than 800 older Catholic clergy members completed the same set of 19 cognitive tests from which previously established composite measures of cognitive domains were derived. Retest effects on some measures were substantial and continued to accumulate even after 8 annual test readministrations, but effects on other measures were minimal. Across cognitive measures, retest effects were not related to age, sex, or education. Individual differences in retest effects were substantial but not consistent across cognitive measures. The results suggest that retest-based improvement in cognitive test performance can be substantial and persistent. 相似文献

Using a national dataset of 820 women who had called the police for an incident of intimate partner violence, this study explored the relationship between several components of socioeconomic status (education, income, and employment), race, and the nature of interactions with police. Over and above the effects of control variables (the presence of an advocate on the scene, the severity of violence in the relationship, and prior calls to police), victims with higher education reported less positive interactions, less control during the interactions, and lower effectiveness of police. Race did not moderate these relationships, and the other components of socioeconomic status were not significantly related to any of the outcomes. Exploratory tests of mediation found that the relationship between education and the quality of interactions with police was explained by the fact that more educated victims felt they had less control in these incidents and were less likely to see the offender arrested. Results also provide evidence for the positive impact of advocates on interactions with police. Implications for research and policy are discussed. 相似文献

In the present study, the efficacy of visual demonstrations and verbal instructions as instructional constraints on the acquisition of movement coordination was investigated. Fifteen participants performed an aiming task on 100 acquisition and 20 retention trials, under 1 of 3 conditions: a modeling group (MG), a verbally directed group (VDG), and a control group (CG). The MG observed a model intermittently throughout acquisition, whereas the VDG was verbally instructed to use the model's movement pattern. Participants in the CG received neither form of instruction. Kinematic analysis revealed that compared with verbal instructions or no instructions, visual demonstrations significantly improved participants' approximation of the model's coordination pattern. No differences were found in movement outcomes. Coordination data supported the visual perception perspective on observational learning, whereas outcome data suggested that the modeling effect is mainly a function of task constraints, that is, the novelty of a movement pattern. 相似文献

Abstract Students who were identified by their teachers as poor spellers were asked to judge the difficulty they would have in spelling each of 100 words that were representative of the sorts of words they tended to misspell in their various subject areas (the spelling ecology). After making difficulty judgments, the students were then asked to spell each word on the list. Spelling errors were scored as either phonetic or nonphonetic. The researchers rated each of the 100 words on ten characteristics: number of letters, syllables, letters per syllable, double and silent letters; schwa, ambiguous, and unusual sounds; and two measures of familiarity to the student. This task was replicated after a four‐week period to check for spelling and judgment consistency. Spelling errors and judgments of spelling difficulty were analyzed using the double system Lens Model using the ten word characteristics as “cues” in the analysis. Results showed only moderate agreement between difficulty judgments and spelling errors, and fairly consistent differences between those word characteristics that were predictive of perceived spelling difficulty and those predictive of phonetic and nonphonetic errors. Several different patterns of cue weights were noted for spelling errors whereas spelling difficulty judgments were primarily based upon word familiarity. Implications are drawn for the further investigation of spelling errors and of how students decide what constitutes a “hard” word to spell and for the potential improvement of the spelling judgment process using cognitive feedback from the Lens Model. The characterization of spelling as a cognitive activity has received increasing attention in the educational research literature. For example, two recent issues of Reading Psychology (Numbers 2 and 3, 1989) were entirely devoted to research on spelling. Much of this work has focused on spelling strategies (e.g., Anderson, 1985, Kreiner & Gough, 1990, and Olson, Logan, & Lindsey, 1989), spelling problems and types of errors (e.g., see Frith, 1980, and Weber & Henderson, 1989), and the relationship between spelling and reading (e.g., Templeton, 1989, and Zutell & Rasinski, 1989). However, there has been very little research on the issues of the criteria individuals use in deciding that a particular word is difficult or easy to spell, and the accuracy and effects of such a decision. We refer here to the more metacognitive aspects of the task ecology of spelling, and the effects of which may be shown in decisions to avoid or at least minimize the cognitive efforts expended in spelling a perceived “hard” word. The issue of judging spelling difficulty forms the focus of the present study. Here we attempt to document those features of a word that make students think it would be hard or easy to spell. We then relate this judgment process to errors made when students attempt to spell words. Finally, we compare the relative importance of various features of words as predictors of both difficulty judgments and actual spelling errors. 相似文献

Abstract Evidence attests to substantial variations in health contingent on socioeconomic position. It is argued that these effects cannot be dismissed as artefact nor can they be explained, in the main, by either social selection or an unequal distribution of accepted behavioural risk factors among different social groups. The most likely explanation would seem to be social causation. However, it is continuing social and material inequality that appears most implicated; accounts which locate the effects in childhood social and material causes are far less compelling. The persistence of socioeconomic health differentials into the materially better-off social strata and the possible determining role of relative as well as absolute living standards suggest that psychological, in addition to material, variables are likely to be involved. Isolating the key psychological variables and identifying the nature of their influences will not be easy tasks, although social relations, psychological stress, uplifts, and control have emerged as possible candidates. However, psychological mediators of this sort most probably constitute surface rather than basic causes. Socio-economic inequality, it is contended, remains the basic cause, and, as such, the proper target for intervention. Psychological interventions are unlikely to yield much in the way of dividends in this context and indeed could inadvertently contribute to victim blaming. 相似文献

Abstract The present study was designed to identify risk factors for psychological morbidity in women attending a one-stop diagnostic clinic with suspected breast disease. A cohort of 158 women were recruited and were asked to complete scales measuring psychological morbidity and psychosocial factors in the period immediately before their appointment and to repeat the assessments of psychological morbidity on the day of the appointment. Relevant clinical and demographic data were also collated. Within the cohort 1.4% of respondents received a diagnosis of malignant disease. Psychological morbidity, both prior to and during the diagnostic appointment was strongly predicted by psychosocial factors (i.e., acceptance-resignation coping, personal self esteem and discrepancies in social support), accounting for 54% and 63% of the variance at pre-appointment and appointment day phases respectively. Other measured variables were found not to be correlated with and/or to account for a significant proportion of the variance in the measures of morbidity. These results suggest that these psychosocial variables should be targeted in interventions designed to reduce psychological morbidity in this patient group. 相似文献

Evidence from a number of investigations suggests a considerable overlap between reading disability (RD) and attention deficit-hyperactivity disorder (ADHD). We investigate the relationship between RD and ADHD in a cohort of 186 children 7.5–9.5 years of age, recruited explicitly to address classification and definitional issues in these disorders. Using multivariate methods, we examine the hypothesis that RD and ADHD represent separate diagnostic entities that frequently co-occur in the same individual. The results suggest that RD is characterized by deficits within the language system, in particular a subcomponent within that system, phonological processing; in contrast, such linguistic deficits are not characteristic of ADHD unless ADHD is associated with RD. When children with both RD and ADHD are examined, both the linguistic deficits associated with RD and the behavioral characteristics associated with ADHD are apparent, but these deficits are not synergistic. We conclude that RD and ADHD represent separate disorders that frequently co-occur. 相似文献
