ObjectivesRosenbaum's [1990. The role of learned resourcefulness in the self-control of health behavior. In M. Rosenbaum (Ed.), Learned resourcefulness: On coping skills, self-control, and adaptive behavior (pp. 3–30). New York: Springer Publishing Company; 2000. The self-regulation of experience: openness and construction. In P. Dewe, A. M. Leiter, &; T. Cox (Eds.), Coping and health in organizations (pp. 51–67). London: Taylor and Francis] model of self-control depicts learned resourcefulness as a key component of the goal attainment process. Despite this model's popularity, few studies have examined its importance in the maintenance of exercise. The transtheoretical model of change has been used instead. The two models, nonetheless, share strikingly similar components with the exception of learned resourcefulness.Design/MethodsOur 265 participants, ranging from wanting to be active to being regular exercisers, completed instruments assessing learned resourcefulness, stage of change for exercise, self-efficacy, reasons for exercising and the processes of change for exercise.ResultsAs predicted, participants in the maintenance stage for exercise were on average more highly resourceful than participants in the contemplation, preparation and action stages of change. Low resourceful participants in the contemplation stage of change were the least likely to be employing strategies to help facilitate activity.ConclusionImplications for exercise promoters are discussed. 相似文献

ObjectivesThe purpose of the present paper is to provide a primer on the understanding of meta-analysis.Design and methodAfter presenting the rationale behind meta-analysis, the present paper defines statistical artifacts of sampling error and measurement.FindingsExamples show that statistical artifacts influence the correlation coefficient. The paper also explains the notions of confidence intervals and credibility intervals and how correlations corrected for sampling error and measurement error are calculated.ConclusionsThe paper concludes by explaining the notion of second-order sampling error and moderator meta-analysis. 相似文献

Within Piaget there is an implicit theory of the development of explicit memory. It rests in the dynamical trajectory underlying
the development of causality, object, space and time – a complex (COST) supporting a symbolic relationship integral to the
explicit. Cassirer noted the same dependency in the phenomena of aphasias, insisting that a symbolic function is being undermined
in these deficits. This is particularly critical given the reassessment of Piaget’s stages as the natural bifurcations of
a self-organizing dynamic system. The elements of a theoretical framework required to support explicit memory are developed,
to include, (1) the complex developmental trajectory supporting the emergence of the explicit in Piaget, (2) the concrete
dynamical system and the concept of a non-differentiable time contained in Bergson’s theory required to support a conscious,
as opposed to an implicit remembrance, (3) the relation to current theories of amnesia, difficulties posed by certain retrograde
amnesic phenomena, the role of the hippocampus and limitations of connectionist models, (4) the fact that nowhere in this
overall framework does the loss of explicit memory imply or require the destruction of experience “stored in the brain.” 相似文献

This paper introduces a symposium discussing Michael Oakeshott's understanding of the relationship of religion, science and politics. Essays by Elizabeth Corey, Timothy Fuller, Byron Kaldis, and Corey Abel are followed by a review of Corey's recent book by Efraim Podoksik. 相似文献

大脑前扣带回皮层与执行功能 总被引:9,自引:2,他引:9
回顾了近期有关大脑前扣带回皮层(ACC)参与执行功能的研究资料。结果显示,ACC可以对正在进行的目标定向行为实施在线监控,在出现反应冲突或错误时提供信号,以便能及时调整与分配注意资源,因此可能是一个行为规划与执行的高级调控结构。这两年来的新发现提示,ACC的执行监控作用可能是基于动机与奖赏期待做出的对“意志行动”的整合性控制,并可能具有对行动结果的情绪评价意义。 相似文献

The accuracy of science depends on the precision of its methods. When fields produce precise measurements, the scientific method can generate remarkable gains in knowledge. When fields produce noisy measurements, however, the scientific method is not guaranteed to work – in fact, noisy measurements are now regarded as a leading cause of the replication crisis in psychology. Scientists should therefore strive to improve the precision of their methods, especially in fields with noisy measurements. Here, we show that automation can reduce measurement error by ∼60% in one domain of developmental psychology: controlled-rearing studies of newborn chicks. Automated studies produce measurements that are 3–4 times more precise than non-automated studies and produce effect sizes that are 3–4 times larger than non-automated studies. Automation also eliminates experimenter bias and allows replications to be performed quickly and easily. We suggest that automation can be a powerful tool for improving measurement precision, producing high powered experiments, and combating the replication crisis. 相似文献

We examined the effects of error correction on spelling accuracy of culturally and linguistically diverse students enrolled in summer Migrant Education. In an error correction strategy, students spelled a word, viewed a correct model, and corrected specific errors. In a traditional strategy, students wrote words three times each while viewing a correct model. Words were presented in Spanish or English. Results showed that students with and without learning disabilities, whose primary language was English, correctly spelled more English words in the error correction condition than the traditional. Students whose primary language was Spanish correctly spelled Spanish words equally well in both conditions, possibly because of the phonetic nature of the Spanish language. 相似文献

A Bayesian framework for making mastery/nonmastery decisions based on multivariate test data is described in this study. Overall, mastery is granted (or denied) if the posterior expected loss associated with such action is smaller than the one incurred by the denial (or grant) of mastery. An explicit form for the cutting contour which separates mastery and nonmastery states in the test score space is given for multivariate normal test scores and for a constant loss ratio. For multiple cutting scores in the true ability space, the test score cutting contour will resemble the boundary defined by multiple test cutting scores when the test reliabilities are reasonably close to unity. For tests with low reliabilities, decisions may very well be based simply on a suitably chosen composite score.This work was performed pursuant to Grant NIE-G-78-0087 with the National Institute of Education, Department of Health, Education, and Welfare, Huynh Huynh, Principal Investigator.

A model is proposed that describes subject behavior on repeat paired comparison preference tests. The model extends prior work in this area in that it explicitly allows for abstentions and permits the derivation of individual true scores for discrimination ability as well as conditional estimates of proportionate preference. With these results, the properties of a paired comparison test can be thoroughly explored. An empirical example is presented, and test design issues are considered. In particular, repeat paired comparison preference tests are shown to be inherently less efficient discrimination tests than are pick 1 of 2 tests. 相似文献

In a Piagetian Stage IV search task in which the object was in plain view under transparent covers, Butterworth (1977) obtained errors from nearly half the infants but noted few errors when the object was uncovered. This study investigates the possibility that errors arise in the former case because novel transparent covers present a particular distraction. Butterworth's results with transparent covers were replicated under his conditions of administration, but virtually no errors were obtained when infants were familiarized with the covers prior to testing. From this and other results it is suggested that errors in search for a visible object only occur when the infant's attention is drawn by other features of the array. 相似文献
