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

认知负荷理论是近年来迅速发展起来的用于解释认知资源分配的心理学理论。临床诊疗工作本质上是医生对患者的病情信息认知加工并进行决策的过程。医生的认知负荷情况决定着医生认知加工的效率,认知加工效率决定了医生的工作效率。提高医生的认知加工效率可以通过对诊疗任务分配的调整,使诊疗任务产生的内在认知负荷与医生所能承受的认知负荷相适应,减少外在认知负荷,增加相关认知负荷三个方面来实现,从而可以提高诊疗的质量和效率,引导医生认知资源的合理分配。  相似文献

认知储备是指个体自适应利用神经网络对不断增加的脑损伤进行补偿的能力, 它能显著影响个体的生理功能、认知功能和行为结果。当前有关认知储备的研究主要集中在认知储备的测量及其在认知老化研究中的应用方面。现有研究尽管已在认知储备的测量及其与认知老化的关系上取得越来越多的共识, 但在诸如认知储备测量的标准化、认知储备与认知衰退率、认知储备与脑病理的关系等问题上还存在较大争议。未来研究除应进一步标准化对认知储备的测量, 进而探讨认知储备的病理机制, 还应关注认知储备对老化的干预研究。  相似文献

To make a convincing argument that cognitive stimulation moderates age trends in cognition there must be (a) a negative relation between age and level of cognitive stimulation, (b) a positive relation between level of cognitive stimulation and level of cognitive functioning, and (c) evidence of an interaction between age and cognitive stimulation in the prediction of cognitive functioning. These conditions were investigated in a study in which 204 adults between 20 and 91 years of age completed an activity inventory and performed a variety of cognitive tasks. Only the 1st condition received empirical support, and, thus, the results of this study provide little evidence for the hypothesis that cognitive stimulation preserves or enhances cognitive functioning that would otherwise decline.  相似文献

认知操作、认知方式与外倾性人格特质的关系   总被引:1,自引:0,他引:1  
张利燕  郑雪 《心理科学》2007,30(3):604-608
对28名外倾被试和28名内倾被试进行实验性认知测试,以考察认知操作、认知方式与外倾性人格特质的关系。结果表明,内外倾被试在含有社会认知操作、非社会认知操作的认知任务的测试总分上没有差异,而在社会认知一非社会认知方式的评价分数上存在显著差异。外倾被试更多地倾向于社会认知型认知方式,内倾被试更多地倾向于非社会认知型认知方式。研究结果支持了外倾性与智力关系的假设:外倾性与社会认知一非社会认知的认知方式存在相关关系,而与认知操作测试总分无关。  相似文献

Research indicates that people with obsessive‐compulsive disorder (OCD) have poor cognitive flexibility. However, studies have largely focused on actual abilities and while individuals' emotional responses may be just as important, little is known about how those with OCD experience a situation that requires cognitive flexibility. It is furthermore largely unknown whether cognitive flexibility may also be important for people with OCD symptoms, rather than only to those with full blown disorders. This study investigates the relationship between cognitive flexibility, and the experience thereof in female students with and without OCD symptoms. It was expected that poor cognitive flexibility would be positively associated to OCD symptoms, and that those with OCD symptoms would display poor cognitive flexibility, and experience situations requiring cognitive flexibility as more difficult, than those without OCD symptoms. Participants completed a measure for OCD symptoms, a neuropsychological task to measure cognitive flexibility, and a self‐report measure assessing emotional experience of situations requiring cognitive flexibility. Positive associations between OCD symptoms and both poor cognitive flexibility and negative experience of situations requiring cognitive flexibility were found. Furthermore, those with OCD symptoms performed poorer on the cognitive flexibility task than those without OCD symptoms, and reported higher scores on the cognitive inflexibility questionnaire. Results confirm a relation between OCD symptoms and poor cognitive flexibility in a subclinical sample and identify a relation between OCD symptoms and a negative experience of situations that require cognitive flexibility. Overall findings suggest that poor cognitive flexibility may be an important part of OCD symptomatology.  相似文献

童年贫困与晚年认知老化的关系尚存争议。有的研究表明, 童年贫困会加速个体的认知老化, 但是也有研究发现童年贫困会延缓个体的认知老化, 这与社会流动性起到的调节作用有关。对于童年贫困个体, 低稳定或者社会经济地位的向下流动(即长期贫困)会使逆境产生的消极影响不断累积, 从而加速个体的认知老化; 而心理韧性高的童年贫困个体, 可能会促使社会经济地位向上流动, 这会增加个体的认知储备, 并提升特定认知能力, 进而延缓认知老化。今后该领域的研究应该探讨童年主观贫困与认知老化之间的关系以及童年贫困对不同认知能力老化的影响, 也应关注童年贫困与晚年认知老化关系研究中的幸存者偏差效应。  相似文献

Although intuitively plausible, the evidence relevant to the mental exercise hypothesis is currently mixed. One of the main controversial issues concerning the investigation of this hypothesis has to do with how cognitive stimulation is assessed. The mental exercise hypothesis was here tested with a subjective and self-reported measure of cognitive stimulation. Overall, results have supported that a greater engagement in cognitively stimulating activities was associated with higher levels of cognitive functioning. However, the rate of cognitive decline with advancing age was not reduced for people who were more mentally active. Of great interest, the subjective measure of cognitive engagement have supported that cognitive demands assessed by participants on activities varied as a function of participants’ cognitive resources: lower cognitive resources were associated with lower perceived cognitive demands.  相似文献

Cognitive enhancement has an increasingly wider influence on our life. The main issue that concerns epistemologists is what its epistemological implications are. Adam Carter and Duncan Pritchard argue that cognitive enhancement improves cognitive achievement, but this view faces axiological objections. A worry exists that cognitive enhancement undermines achievements and erodes intellectual character. Crucially, two parties seem to talk past each other because the nature of cognitive enhancement and the value of cognitive enhancement are not clearly distinguished. To end the stand‐off between the two parties, I take insight from Gwen Bradford’s work and argue that, other things being equal, cognitive enhancement either decreases the value of cognitive achievement or undermines cognitive achievement. In the face of this threat, I further submit that we could learn to live with cognitive enhancement in an integrated way so that the lost value can be restored.  相似文献

The main purpose of this article is to examine whether cognitive plasticity increases after cognitive training in Alzheimer's disease patients. Twenty six patients participated in this study, all of them diagnosed with mild Alzheimer's disease, 17 of them received a cognitive training program during 6 months, and the other 9 were assigned to the control group. Participants were assigned to experimental or control conditions for clinical reasons. In order to assess cognitive plasticity, all patients were assessed before and after treatment with three subtests from the "Bateria de Evaluación de Potencial de Aprendizaje en Demencias" [Assessment Battery of Learning Potential in Dementia] (BEPAD). After treatment, Alzheimer's disease patients improved their performance in all the tasks assessing cognitive plasticity: viso-spatial memory, audio-verbal memory and verbal fluency. However, the cognitive plasticity scores of the patients in the control group decreased. In conclusion, this study showed that cognitive stimulation programs can improve cognitive functioning in mildly demented patients, and patients who do not receive any cognitive interventions may reduce their cognitive functioning.  相似文献

Cognitive systems research has predominantly been guided by the historical distinction between emotion and cognition, and has focused its efforts on modelling the “cognitive” aspects of behaviour. While this initially meant modelling only the control system of cognitive creatures, with the advent of “embodied” cognitive science this expanded to also modelling the interactions between the control system and the external environment. What did not seem to change with this embodiment revolution, however, was the attitude towards affect and emotion in cognitive science. This paper argues that cognitive systems research is now beginning to integrate these aspects of natural cognitive systems into cognitive science proper, not in virtue of traditional “embodied cognitive science”, which focuses predominantly on the body’s gross morphology, but rather in virtue of research into the interoceptive, organismic basis of natural cognitive systems.  相似文献

认知损害有关的病理机制、危险因素研究由来已久,但尚未找到有效治疗认知损害的途径,认知损害的保护性因素研究进而成为研究者们关注的热点。前人的研究显示活动参与对认知损害具有积极的影响,可能是认知损害的重要保护性因素,但活动参与对认知损害的影响机制以及各活动之间存在的交互作用仍不明确。未来的研究可着重探讨不同活动类型及其交互作用同认知损害的关系,并分析活动参与对认知损害起保护作用的公共因子。  相似文献

ProblemThere has been a recent upsurge of research interest in cognitive sport psychology or the scientific study of mental processes (e.g., mental imagery) in athletes. Despite this interest, an important question has been neglected. Specifically, is research on cognitive processes in athletes influential outside sport psychology, in the “parent” field of cognitive psychology or in the newer discipline of cognitive neuroscience?ObjectivesThe purpose of this paper is to explore the theoretical significance of research on expertise, attention and mental imagery in athletes from the perspective of cognitive psychology and cognitive neuroscience.MethodFollowing analysis of recent paradigm shifts in cognitive psychology and cognitive neuroscience, a narrative review is provided of key studies on expertise, attention and mental imagery in athletes.Results and conclusionsThis paper shows that cognitive sport psychology has contributed significantly to theoretical understanding of certain mental processes studied in cognitive psychology and cognitive neuroscience. It also shows that neuroscientific research on motor imagery can benefit from increased collaboration with cognitive sport psychology. Overall, I conclude that the domain of sport offers cognitive researchers a rich and dynamic natural laboratory in which to study how the mind works.  相似文献

A central tenet of Beck’s cognitive therapy (or cognitive behavior therapy) of the emotional disorders is that change in negative thought and beliefs is necessary for clinically significant symptom reduction in anxiety, depression, and other psychological conditions. Cognitive restructuring, a uniquely Beckian innovation, is a treatment strategy that directly targets cognitive reappraisal as the change mechanism responsible for symptom reduction. This commentary considers the origins of cognitive reappraisal in Beck’s cognitive therapy through the lens of cognitive restructuring and what treatment process research tells us about the mechanisms of change in cognitive restructuring.  相似文献

Transdiagnostic cognitive behavioral interventions target different cognitive processes to promote mental health, including cognitive fusion and cognitive reappraisal. Determining the relative impact of cognitive fusion and reappraisal on a range of student mental health concerns could help interventions target psychopathological cognitive processes more effectively. Therefore, this study examined the longitudinal impact of cognitive fusion and reappraisal on mental health and functioning outcomes. A series of hierarchical regression models tested the effects of cognitive fusion and reappraisal in a sample of college students (n = 339). When controlling for reappraisal and baseline symptoms, fusion predicted distress, depression, generalized anxiety, social anxiety, hostility, academic distress, and student role problems 1 month later. Reappraisal predicted only student role problems longitudinally when controlling for fusion. These results suggest that cognitive fusion is a stronger predictor than reappraisal for a range of student mental health concerns and may be a particularly important target for improving student mental health.  相似文献
