Feedback-based learning declines with age. Because older adults are generally biased toward positive information (“positivity effect”), learning from positive feedback may be less impaired than learning from negative outcomes. The literature documents mixed results, due possibly to variability between studies in task design. In the current series of studies, we investigated the influence of feedback valence on reinforcement learning in young and older adults. We used nonprobabilistic learning tasks, to more systematically study the effects of feedback magnitude, learning of stimulus–response (S–R) versus stimulus–outcome (S–O) associations, and working-memory capacity. In most experiments, older adults benefitted more from positive than negative feedback, but only with large feedback magnitudes. Positivity effects were pronounced for S–O learning, whereas S–R learning correlated with working-memory capacity in both age groups. These results underline the context dependence of positivity effects in learning and suggest that older adults focus on high gains when these are informative for behavior. 相似文献

The effect of concurrent visual feedback on the implicit learning of repeated segments in a task of pursuit tracking has been tested. Although this feedback makes it possible to regulate the positional error during the movement, it could also induce negative guidance effects. To test this hypothesis, a first set of participants (N?=?42) were assigned to two groups, which performed either the standard pursuit-tracking task based on the experimental paradigm of Pew (1974; group F-ST), or a task called “movement reproduction” in which the feedback was suppressed (group noF-ST). A second set of participants (N?=?26) performed in the same feedback condition groups but in a dual-task situation (F-DT and noF-DT; Experiment 2). The results appear to confirm our predictions since the participants in groups without feedback, contrary to those in groups with feedback, succeeded with practice in differentiating their performances as a function of the nature of the segments (repeated or nonrepeated) both in simple (Experiment 1) and in dual-task (Experiment 2) situations. These experiments indicate that the feedback in the pursuit-tracking task induces a guidance function potentially resulting in an easiness tracking that prevents the participants from learning the repetition. 相似文献

An internal clock-like process has been implicated in the control of rhythmic movements performed for short (250–2,000 ms) time scales. However, in the past decade, it has been claimed that a clock-like central timing mechanism is not required for smooth cyclical movements. The distinguishing characteristic delineating clock-like (event) from non-clock-like (emergent) timing is thought to be the kinematic differences between tapping (discrete-like) and circle drawing (smooth). In the archetypal event-timed task (tapping), presence of perceptual events is confounded with the discrete kinematics of movement (table contact). Recently, it has been suggested that discrete perceptual events help participants synchronize with a metronome. However, whether discrete tactile events directly elicit event timing has yet to be determined. In the present study, we examined whether a tactile event inserted into the circle drawing timing task could elicit event timing in a self-paced (continuation) timing task. For a majority of participants, inserting an event into the circle drawing task elicited timing behaviour consistent with the idea that an internal timekeeper was employed (a correlation of circle drawing with tapping). Additionally, some participants exhibited characteristics of event timing in the typically emergently timed circle drawing task. We conclude that the use of event timing can be influenced by the insertion of perceptual events, and it also exhibits persistence over time and over tasks within certain individuals. 相似文献

How accurate are explicit judgements about familiar forms of object motion, and how are they made? Participants judged the relations between force exerted in kicking a soccer ball and variables that define the trajectory of the ball: launch angle, maximum height attained, and maximum distance reached. Judgements tended to conform to a simple heuristic that judged force tends to increase as maximum height and maximum distance increase, with launch angle not being influential. Support was also found for the converse prediction, that judged maximum height and distance tend to increase as the amount of force described in the kick increases. The observed judgemental tendencies did not resemble the objective relations, in which force is a function of interactions between the trajectory variables. This adds to a body of research indicating that practical knowledge based on experiences of actions on objects is not available to the processes that generate judgements in higher cognition and that such judgements are generated by simple rules that do not capture the objective interactions between the physical variables. 相似文献

ABSTRACTPrevious research (Sharman & Calacouris, 2010. Motivated imagination inflation: Implicit and explicit motives predict imagination inflation for achievement and affiliation events. Experimental Psychology, 57, 77–82) found that participants’ achievement-motivation was associated with the inflation of memory and confidence for unlikely achievement-related events in childhood. Similarly, other research has shown correlations between achievement motivation and grade inflation. In the current studies, we experimentally investigate the effect of false feedback and achievement-motivation on memory distortion for an unlikely childhood event (e.g. inventing an important device). In Experiment 1, we found that false feedback did have an effect, but contrary to previous research, self-reported achievement-motivation was not a statistically significant correlate of memory distortion. In Experiment 2, we again found a main effect for false feedback, no main effect of motivation, and an interaction. Both Experiments did not find, as earlier research had, a significant relationship between achievement-motivation and achievement-related memory distortion. We suggest others use different methods to ours when attempting to demonstrate a causal relationship between motivation and false memories. 相似文献

上级反馈对员工行为的影响 总被引:8,自引:1,他引:7
采用2×2(反馈方式、反馈对象)两因素组间实验设计,选取303名被试考察了上级反馈对员工积极整合行为倾向、冲突行为倾向和中立行为倾向的影响,以及个人主义-集体主义倾向对这种影响的调节作用。结果表明,Singelis、Triandis等人有关个人主义、集体主义的理论框架基本适合中国被试,个体的个人主义、集体主义倾向对反馈的效果起到一定的调节作用。领导的反馈方式、反馈针对的对象对员工的行为主效应都显著,上级的表扬会增加员工的中立行为倾向,针对个人的反馈会引起较强的冲突行为倾向。 相似文献

Emotional intelligence (EI) may promote more effective decision-making under stress. In the present study, 167 participants completed a situation judgment test for EI, and performed a decision-making task based on an Antarctic rescue scenario. Participants were assigned to either a negative or neutral feedback group. Negative feedback significantly increased distress and impaired decision-making. EI failed to moderate the impacts of negative feedback, but higher EI was associated with greater information-search activity irrespective of feedback condition. It is concluded that ability EI may have a motivational component that may support more exhaustive analysis of both social and non-social stimuli. 相似文献

This study compared the effects of immediate self-correction, delayed self-correction, and no correction on the acquisition and maintenance of multiplication facts by a fourth-grade student with learning disabilities. Data from daily and maintenance tests indicated that both correct response rate and accuracy were higher when self-correction was immediate rather than delayed or absent. 相似文献

We reviewed 49 studies which used direct observation procedures to provide data on the effects of pre-service and inservice training in practical classroom teaching behaviors and skills. We found stronger effects for training packages which included classroom practice with performance feedback. The research provided conflicting evidence regarding the value of modeling, role-play, cueing systems, and contingency management components in practical skills training. The weakest training effects were those produced by microteaching, Minicourse, and protocol training packages. Twenty of the evaluations also provided follow-up data but the design of these studies did not permit any conclusions to be drawn regarding the training conditions which are necessary for the maintenance of newly acquired classroom teaching skills. We concluded that identification of the training conditions which are necessary for the maintenance of new teaching skills will require more thoughtful conceptualizations of maintenance and its measurement, and more carefully designed component analyses of those factors suggested by basic research as being necessary for maintenance. 相似文献
