ObjectivesTo examine the influence of efficacious beliefs on affective states, enjoyment, and satisfaction after performing a maximal intensity exercise task (i.e. Sprint Interval Training (SIT).DesignAn experimental design was utilized and participants were randomized to a high self-efficacy feedback (HE), low self-efficacy feedback (LE), or no feedback control condition.MethodsCollege-aged men and women (n = 74) performed four 30-second maximal sprints, interspersed with 4-min breaks. Following each sprint interval, participants received either positive, negative or no feedback and SIT self-efficacy, affective states (i.e., positive well-being, psychological distress, fatigue), heart rate (HR), and ratings of perceived exertion (RPE) were assessed. Upon terminating the exercise session, enjoyment and satisfaction were assessed.ResultsThere was group equivalency in HR and RPE among participants of each group. The HE group had significantly less of a decline in SIT self-efficacy from pre to post SIT than both the LE and control groups, and reported significantly higher levels of exercise enjoyment than the other two groups. In addition, the HE and control groups reported significantly higher satisfaction than the LE group.ConclusionsWe recommend that exercisers receive positive feedback statements while performing SIT to minimize the decrease in SIT self-efficacy and to bolster feelings of enjoyment and satisfaction. 相似文献

Psychologists and philosophers tend to treat expertise as a property of special individuals. These are individuals who have devoted much more time than the general population to the acquisition of their specific expertises. They are often said to pass through stages as they move toward becoming experts, for example, passing from an early stage, in which they follow self-conscious rules, to an expert stage in which skills are executed unconsciously. This approach is ‘one-dimensional’. Here, two extra dimensions are added. They are drawn from the programme known as Studies of Expertise and Experience (SEE) and its ‘Periodic Table of Expertises’. SEE, which is sociological, and/or Wittgensteinian, in inspiration, takes expertise to be the property of groups; there are ‘domains’ of expertise. Under SEE, level of expertise grows with embedding in the society of domain experts; the key is the transmission of domain-specific tacit knowledge. Thus, one extra dimension is degree of exposure to tacit knowledge. Under SEE, domains can be big or small so there can be ‘ubiquitous tacit knowledge’, such as natural-language-speaking or other elements of general social behaviour, which belong to every member of a society. The second extra dimension is, therefore, ‘esotericity’. The resulting three-dimensional ‘expertise-space’ can be explored in a number of ways which reveal the narrowness of the analysis and the mistakes that have been made under the one-dimensional model. 相似文献

Most previous works on responsible conduct of research have focused on good practices in laboratory experiments. Because computation now rivals experimentation as a mode of scientific research, we sought to identify the responsibilities of researchers who develop or use computational modeling and simulation. We interviewed nineteen experts to collect examples of ethical issues from their experiences in conducting research with computational models. We gathered their recommendations for guidelines for computational research. Informed by these interviews, we describe the respective professional responsibilities of developers and users of computational models in research. In particular, we examine whether developers should disclose the full computational codes, and we explain how developers and users should minimize harms from improper uses of models. 相似文献

How would religion and a life event carrying an existential threat (LEET) jointly impact a person's life goals of becoming wealthy and successful in one's career? Goal reprioritisation, socioemotional selectivity, and gerotranscendence theories predict a shift away from material goals following a LEET, independent of the effect of religion. However, terror management theory (TMT) predicts that the effect of death thoughts depends on one's prevailing cultural values. As religion can be regarded as a culture, it is possible that Christians' and non-believers' material life goals would be differentially altered by LEET. Data from 1259 young Chinese adults reveal no main effect of LEET, but a strong effect of religion. Moreover, there was an interaction effect between LEET and religion on material life goals: LEET weakened material goals for Christians but not for non-believers. These findings suggest that TMT is more suitable than the other theories for predicting life goal changes. 相似文献

Creativity and Aging: Personal Journals and the Creation of Self 总被引:1,自引:0,他引:1
Harry J. Berman 《Journal of Aging and Identity》1998,3(1):3-9
This article considers the writing of personal journals as a process through which an individual constructs a linguistic representation of one's self, with the self constituting a narrative. Rather than a fixed narrative, one's life exists as a narrative subject to revision and reinterpretation. Through journal writing, then, one constructs and reconstructs his or her identity. Berman finds the value in personal journals not only in the themes that surface but also in the creative process they reveal. In this article, he examines passages from five journalists that demonstrate this process of creating and revising meaning in one's life. 相似文献

Junior kindergarten children, third-grade children, and college students were given a simultaneous pattern discrimination task, with simple and complex patterns, under either unlimited or limited (150 msec) viewing time. Under unlimited viewing, RTs to same patterns were faster than to different patterns for younger children and older males. Under limited viewing, same and different RTs were equivalent, but more errors were made in judging different patterns by all age groups. The RTs were longer to complex than to simple patterns, but the increase was differentially less for the youngest Ss, especially on same pairs. Since this age difference was found under both limited and unlimited viewing, it was not attributable to age differences in perceptual scanning strategies. The same-different asymmetry in RT under unlimited viewing and in error rate under limited viewing confirms across a wide age range previous findings with adults using codable stimuli. A two-process model for same and different judgments appears to be required, although young children may have had a response bias for same in Expt II. 相似文献

Rhesus monkeys were given 960 delayed response (DR) problems. The incentive was either visible or not visible during the baiting phase of each problem, and a 0-, 5-, 10-, or 20-sec intraproblem delay was imposed. Performance was substantially better when the incentive could be seen during the baiting phase. When the incentive was visible during baiting, at all stages of training performance decreased as a function of increased chance levels after short delays, and the rate of improvement with training was comparable after each of the four intraproblem delays. When the incentive was not visible during the baiting phase, an inverse relationship between performance and delay duration became evident only during the later stages of training. On the initial problems performance was at chance levels, and although improvement with training was evident, the rate of this improvement was inversely related to delay duration. The findings were interpreted in terms of Fletcher's orienting response analysis of DR performance. 相似文献
