The Relationship between Everyday Problem Solving and Inconsistency in Reaction Time in Older Adults
Catherine L. Burton Esther Strauss David F. Hultsch Michael A. Hunter 《Neuropsychology, development, and cognition. Section B, Aging, neuropsychology and cognition》2013,20(5):607-632
ABSTRACT The purpose of the present study was to investigate whether inconsistency in reaction time (RT) is predictive of older adults' ability to solve everyday problems. A sample of 304 community dwelling non-demented older adults, ranging in age from 62 to 92, completed a measure of everyday problem solving, the Everyday Problems Test (EPT). Inconsistency in latencies across trials was assessed on four RT tasks. Performance on the EPT was found to vary according to age and cognitive status. Both mean latencies and inconsistency were significantly associated with EPT performance, such that slower and more inconsistent RTs were associated with poorer everyday problem solving abilities. Even after accounting for age, education, and mean level of performance, inconsistency in reaction time continued to account for a significant proportion of the variance in EPT scores. These findings suggest that indicators of inconsistency in RT may be of functional relevance. 相似文献

ABSTRACT This study investigates how cognition influences activities of daily living and health-related quality of life in 85-year-olds in Sweden (n?=?373). Data collection included a postal questionnaire comprising demographics and health-related quality of life measured by the EQ-5D. The ability to perform personal activities of daily living (PADL) was assessed during a home visit that included administering the Mini Mental State Examination (MMSE). Cognitive impairment was shown in 108 individuals (29%). The majority were independent with respect to PADL. A larger number of participants with cognitive impairment reported that they needed assistance in instrumental activities of daily living (IADL) compared to the group without cognitive impairment. Impaired cognition was significantly related to problems with IADL. Significant but low correlations were found between cognition and health-related quality of life – higher ratings on perceived quality of life correlated with higher results on the MMSE. 相似文献

An existing large data set, the Health and Retirement Study (HRS) with the subsequent addition of the Consumption and Activities Mail Survey (CAMS) data, provides a rich data set for the examination of the activities of older adults. In this study HRS and CAMS data are used to examine relationships between various activities of daily living (ADLs) and well-being in older adults. Using structural equation modeling, influences of direct and indirect factors that affect older individuals' cognitive and emotional well-being are analyzed. The data suggest ability to perform ADLs has little to do with cognitive well-being, but is an influential factor in determining emotional well-being. 相似文献

The present study aimed to examine the effects of attachment, social support and resilience on posttraumatic stress disorder (PTSD) symptoms in people living with HIV/AIDS. One hundred fifty-two HIV+ adults in China were investigated. The results suggested that attachment anxiety had a significant direct effect on PTSD symptoms and impacted PTSD symptoms indirectly though associations with social support and resilience. Attachment avoidance could also be considered a distal risk factor of PTSD symptoms via the mediation of social support and resilience. The findings highlight the importance of identifying trauma and PTSD symptoms in people affected by HIV/AIDS and suggest that people with attachment anxiety and low social support resources might be at high risk for PTSD. 相似文献

This paper explores the notion of sensing (Empfinden) as developed by Erwin Straus. It argues that the notion of sensing is at the center of Strauss's thought about animal and
human experience. Straus's originality consists in approaching sensory experience from an existential point of view. Sensing is not a mode of knowing. Sensing is distinguished from perceiving but is still a mode of relation
to exteriority, and is situated on the side of what is usually called affectivity. At the same time Strauss redefines the
field of that which is commonly characterized as affectivity. Sensing designates a stratum that lies deeper than the division
between perceiving and feeling (s'éprouver), a self-affection that is not an alternative to the opening upon exteriority. It corresponds to a mode of immediate communication,
to a sympathy with the world that does not entail any thematic dimension, but does not fall back into a blind fusion. Rather,
sensing is something in the living being's mode of moving that is irreducible, and that includes a tending toward something.

风险决策中, 末期效应指“个体在重复多轮决策任务的末尾冒险倾向升高”的现象, 但其内在机制尚不明确。三个研究的结果发现, 在实验室环境和自然环境下, 不同期望(负期望值和等期望值)条件下被试在最后一轮的投资均会显著增加, 末期效应稳定出现, 且不受到最后一轮决策前被试所拥有的代币数量的影响。即, 就算在风险选项收益更小的情况下, 被试也会倾向于在最后一轮选择高风险选项, 且这一效应是参照点独立的, 这说明末期效应的出现是源于对情绪满足感的追求。未来研究可从这一点切入, 进一步研究情绪影响风险决策过程的机制。 相似文献
