Previous research has suggested a correlation between some linguistic patterns and the risk for Alzheimer’s disease (AD). There is increasing clinical need to identify factors that can be used alone or in combination to predict the onset of AD. The purpose of the present study was to explore the association of language skills and genetic risk for Alzheimer’s disease. Oral and written language samples of cognitively normal women with a susceptibility gene for AD (ApoE e4) were compared to those of noncarriers on measures of grammatical complexity, topic relevance, and talkativeness by observers unaware of participant genotypes. Participants included 29 ApoE e4 carriers 49-73 years of age, and 29 e4 noncarriers 48-76 years of age, most of whom had a first-degree relative with AD. Carriers and noncarriers were group matched for age, educational level, and estimated IQ. Participant groups did not differ significantly in language complexity or topic relevance. However, the ApoE e4 group was significantly more talkative than the noncarrier group (p < .05). 相似文献

Objective: Perceived variety represents a psychosocial experience that gives rise to, and supports the maintenance of, an individual’s well-being. In this study, we developed an instrument to measure perceived variety in exercise (PVE), and examined whether ratings of PVE predict unique variance in indices of exercise-related well-being in addition to that explained by satisfaction of the three basic psychological needs (for competence, relatedness and autonomy) embedded within self-determination theory (SDT). We also examined the extent to which variance in perceived variety is empirically distinct from (or subsumed by) competence, relatedness and autonomy in the context of exercise.Methods: A convenience sample of community adults (N?=?507) completed online surveys twice over a six-week period (n?=?367).Results: PVE was found to prospectively predict unique variance in indices of exercise-related well-being, in addition to that explained by perceived competence, relatedness and autonomy. Using exploratory and confirmatory factor analytic procedures, perceived variety was found to be empirically distinct from perceived competence, relatedness and autonomy.Conclusion: Results from this work suggest that perceived variety holds potential for theoretical and applied advancements in understanding and predicting well-being in exercise settings. 相似文献

Parent tutoring has been successfully used to increase children’s oral reading fluency. However, commonly used procedures
pose a challenge for parents who are not proficient in reading or who speak English as a second language. A taped reading
program that included listening passage preview, repeated reading, and performance feedback was developed for parental implementation
during home tutoring sessions. A multiple baseline design across participants was used to evaluate the effects of parent tutoring
on the oral reading fluency of two elementary-aged English language learners. Data were collected on oral reading fluency
using high- and low-word overlap passages. Results revealed an immediate increase in generalized oral reading fluency for
one child upon intervention implementation and continued growth for both children 2 months following termination. Findings
suggest recorded readings was an effective and acceptable parent tutoring intervention for increasing reading performance
for language minority families. 相似文献

The dopaminergic system is implicated in depressive disorders and research has also shown that dopamine constricts lexical/semantic networks by reducing spreading activation. Hence, depression, which is linked to reductions of dopamine, may be associated with increased spreading activation. However, research has generally found no effects of depression on spreading activation, using semantic priming paradigms. We used a different paradigm to investigate the relationship between depression and spreading activation, one based on word frequencies. Our sample included 97 undergraduates who completed the BDI-II and the Controlled Oral Word Association test as well as the Animal Naming test. The results indicated that the group scoring within the depressed ranged evidenced greater spreading activation as compared to those who scored within the normal range on the BDI-II. The implications of these results as they relate to creativity in depression is discussed. 相似文献

ObjectiveThe study had two objectives 1) to test the fit of the Health Action Process Approach (HAPA) model for sport participation among individuals with acquired physical disabilities and 2) to estimate the extent to which athletic identity predicts intentions to engage in sport within the context of HAPA.DesignProspective cohort of 82 women and 19 men with acquired permanent disabilities (Mage = 44.0; Myears post-injury = 16.2; %in sport = 61.7%).MethodAll HAPA indicators and athletic identity were assessed at baseline and sport participation was assessed using the Leisure Time Physical Activity Questionnaire for People with Spinal Cord Injury two weeks later. Structural equation modelling was used to test the HAPA model.ResultsThe HAPA constructs explained 15% of the variance in sport participation and 18% of the variance when athletic identity was added to the model. Instrumental (β = .21), affective (β = .15), and negative outcome expectancies (β = ?.20) were significant predictors of intentions to participate in sport, as was athletic identity (β = .25). Intentions to participate in sport significantly predicted planning (β = .54) yet there was no direct relationship between planning and sport participation (β = ?.008; p > .05). When the relationship between planning and maintenance self-efficacy was reversed, planning had a significant indirect effect on sport participation through maintenance self-efficacy (β = .33).ConclusionThe HAPA model is a good predictive model for sport participation among those with acquired physical disabilities; furthermore, athletic identity accounts for additional variance in sport participation. These constructs can be valuable components of sport promotion programs for this population. 相似文献

Time to contact (TTC) is specified optically by tau, and studies suggest that observers are sensitive to this information. However, TTC judgements also are influenced by other sources of information, including pictorial depth cues. Therefore, it is useful to identify these sources of information and to determine whether and how their effects combine when multiple sources are available. We evaluated the effect of five depth cues on TTC judgements. Results indicate that relative size, height in field, occlusion, and motion parallax influence TTC judgements. When multiple cues are available, an integration (rather than selection) strategy is used. Finally, the combined effects of multiple cues are not always consistent with a strict additive model and may be task dependent. 相似文献

Children's reasoning about the willingness of peers to convey accurate positive and negative performance feedback to others was investigated among a total of 179 6‐ to 11‐year‐olds from the USA and China. In Study 1, which was conducted in the USA only, participants responded that peers would be more likely to provide positive feedback than negative feedback, and this tendency was strongest among the younger children. In Study 2, the expectation that peers would preferentially disclose positive feedback was replicated among children from the USA, and was also seen among younger but not older children from China. Participants in all groups took the relationship between communication partners into account when predicting whether peers would express evaluative feedback. Results of open‐ended responses suggested cross‐cultural differences, including a greater emphasis by Chinese children on the implications of evaluative feedback for future performance, and reference by some older Chinese children to the possibility that positive feedback might make the recipient ‘too proud’. 相似文献

Anxiety sensitivity refers to the fear of anxiety-related physical sensations arising from beliefs that these sensations have harmful consequences (Reiss & McNally, 1985). The present study examined whether individuals with high (vs. low) anxiety sensitivity show stronger implicit associations in memory between anxiety-related symptoms, as opposed to neutral body parts, and harmful, as compared to harmless, consequences. A total of 22 undergraduate students (14 F, 8 M) completed the Extrinsic Affective Simon Task (EAST; De Houwer, 2003). Results indicated that high anxiety sensitive individuals (n = 10) tended to implicitly associate harmful consequences with anxiety-related symptoms. Their performance was significantly faster on trials where target words related to anxiety symptoms were mapped on to the same response key as harmful consequences. No significant difference in performance was found for low anxiety sensitive individuals (n = 12) or when target words were body parts unlikely related to diseases. Between-group differences persisted after controlling for trait anxiety and history of panic attacks, but not when illness-related beliefs were introduced as a covariate. Identifying this implicit association bias provides additional empirical support for the concept of anxiety sensitivity. 相似文献
