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 The goal of the current project was to examine whether engagement in intellectual/cultural activities explains the long-term effects of education on cognitive abilities throughout adulthood, and whether it compensates for educational differences in cognitive abilities throughout adulthood. Participants between 18 and 96 years of age completed a comprehensive questionnaire about intellectual/cultural activities that they participated in and performed a wide variety of cognitive tests. There were no mediation effects of engagement in intellectual/cultural activities on the relationship between education and cognitive functioning. In contrast, engagement in intellectual/cultural activities was found to moderate the relations between education and the level of fluid ability, working memory, speed of processing, and episodic memory. Findings suggest that the risk of cognitive decline in people with less education can be reduced via engagement in intellectual and cultural activities throughout adulthood. 相似文献

This narrative review considers the positive side of the work-family interface. It surveyed a range of relevant literature (1960–2012) using search terms on the positive work-family interface. From the literature it is evident that various concepts (e.g., work-family enhancement, work-family positive spillover, work-family facilitation and work-family enrichment) are used to conceptualise the positive side of the work-family interface. Further research is needed to explore the positive side of the work-family interface. Findings showed that only a few studies on the positive work-family interface phenomenon have been reported from the South African population, but there is still a huge gap in the South African literature regarding the positive work-family interface. 相似文献

Despite the therapeutic potential of human embryonic stem (HES) cells, many people believe that HES cell research should be banned. The reason is that the present method of extracting HES cells involves the destruction of the embryo, which for many is the beginning of a person. This paper examines a number of compromise solutions such as parthenogenesis, the use of defective embryos, genetically creating a “pseudo embryo” that can never form a placenta, and determining embryo death, and argues that none of these proposals are likely to satisfy embryoists, that is, those who regard the embryo as a person. This paper then proposes a method of extracting HES cells, what might be called the Blastocyst Transfer Method, that meets the ethical requirements of embryoists, and it considers some possible concerns regarding this method. It concludes by encouraging future HES cell research to investigate this method. 相似文献

The role of causal attribution in affect transfer of primes was addressed by examining the consequences of explicit evaluation of primes within the framework of the affect misattribution procedure (AMP; Payne, Cheng, Govorun, & Stewart, 2005). We reasoned that affect transfer occurs when primed affect remains diffuse and not bound to a specific object, hence capable of freely colouring subsequent evaluations of ambiguous objects. Accordingly, we propose that when people explicitly evaluate the prime, affect is clearly bound to the prime and becomes less capable of influencing subsequent judgements. Supporting this notion, affect transfer in the AMP was observed when participants ignored the primes, thereby keeping the primed affect relatively unbound. However, this effect disappeared when participants explicitly evaluated the primes before target stimuli were presented. Implications of these findings in determining how and when affect arising from one object carries over to another is discussed. 相似文献

评述基于认知加工的第二语言习得研究 总被引:1,自引:0,他引:1
认知加工研究范式是第二语言习得内在因素研究的一个重要方法,它代表第二语言习得向计量研究发展的方向。这一范式注重研究习得动态过程,不仅关注学习者习得什么和为什么能习得,更关注学习者是怎样掌握目标语规则的过程。除了计量研究特点外,该范式还从语言本体研究范式合理吸收了有关理论和方法,这些对汉语作为第二语言习得研究都具有借鉴意义。 相似文献

Two experiments investigated the derived transfer of functions through equivalence relations established using a stimulus pairing observation procedure. In Experiment 1, participants were trained on a simple discrimination (A1+/A2-) and then a stimulus pairing observation procedure was used to establish 4 stimulus pairings (A1-B1, A2-B2, B1-C1, B2-C2). Subsequently, a transfer of the simple discrimination functions through equivalence relations was observed (e.g., C1+/C2-). These procedures were modified in Experiment 2, which demonstrated that spider-fearful and non-spider-fearful participants show differing levels of a transfer of self-reported arousal functions for stimuli used in equivalence relations with video-based material depicting scenes with spiders. The results demonstrate that the stimulus pairing observation procedure provides a viable alternative to matching-to-sample, and also offer tentative support for a derived-relations model of the acquisition of anxiety responses in at least one sub-clinical population. 相似文献

A new form of visual representation of divine others is emerging: photography. I examine here a set of photos of deities related to an apparition claim. The goal I pursue is to analyze the self-constitutive features of these pictures – how they produce what they claim to be. I argue that the “presence' of the deities in the photos is achieved through “incarnation practices.' But these pictures are not just a factual representation of alleged mystical events. They constitute an update and a variation on the “Grand Christian Narrative' wherein the factual poses the moral problem of belief. In that sense, divine photography does not modify the epistemology of religious belief. 相似文献

The literature on neuropsychological intervention (NI) uses a variety of terms to refer to equivalent constructs, making it difficult to compare intervention programmes and their outcomes. The purpose of this work is to propose a unified terminological framework for describing NI programmes. The terminological framework was developed based on a previous proposal for common terminology by Johnstone and Stonnington (Rehabilitation of neuropsychological disorders: A practical guide for rehabilitation professionals. Psychology Press, 2011) and driven by Cognitive Psychology concepts. The terminological framework was organized into two sections: (a) NI, which includes types of NI, methods and approaches, instructional methods, and strategies; and (b) neurocognitive functions, which include temporal and spatial orientation, sensation, perception, visuo-constructional abilities, attention, memory, language, reasoning of several sorts (e.g., abstract reasoning, and numerical reasoning), and executive functions. Most NI tasks target a main neurocognitive function, but there are underlying neurocognitive functions that may impair performance in the former. Since it is difficult to create a task that is solely focused on one neurocognitive function, the proposed terminology should not be viewed as a taxonomy, but rather as dimensional, with the same task allowing to work different functions, in varying grades. Adopting this terminological framework will allow to define the targeted neurocognitive functions more accurately and simplify the comparison between NI programmes and their outcomes. Future research should focus on describing the main techniques/strategies for each neurocognitive function and non-cognitive interventions. 相似文献

A program to teach three severely retarded adults to use a side-of-the-foot soccer pass was evaluated. A 9-step stimulus-response chain was taught using forward chaining. In contrast to usual practice, intensive physical prompts were provided initially to teach each response component, then systematically faded. Approximately 20 lessons (trials) were presented in 20-min sessions. A multiple baseline across subjects design showed that the three trainees achieved the no-prompt criterion after 24, 29, and 22 sessions, respectively. Subanalyses indicated that successive response components were learned only after training was implemented. Follow-up data were obtained 57 and 276 days later in the training room and in a gymnasium; in both settings, criterion was achieved with fewer than three reinstructions. 相似文献
