The Role of Scheduling in Learning Through Observation

In the 2 experiments reported in the present article, participants (N = 40, Experiment 1; N = 60, Experiment 2) learned to solve complex puzzles under different schedules of physical practice, observation, or a combination of the two. The results of both studies indicated that observation, in the absence of any physical practice, allows the development of an accurate but relatively nonfunctional cognitive representation. The data suggest that, even when the motor demands are minimal, the functional significance of the cognitive representation is not maximally realized until physical interaction with the task is possible. Thus, providing the participant with an interspersed practice schedule during acquisition enables that interaction to occur, thereby allowing the absolute number of physical practice trials to be reduced and replaced by observation trials, but leading to equivalent learning.     

Effect of Concurrent Visual Feedback Frequency on Postural Control Learning in Adolescents

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.     

A Study in Learning to Walk the Tight Wire

Abstract

     

Attention to Visual Feedback in Motor Learning

Visual guidance and movement to a stop were used to train subjects to make a simple movement without experiencing error in practice. Movement to a stop led to test performance as accurate as that after training with KR, but visual guidance did not. If a continuous visual cue as well as a stop were present during practice, subjects also performed less accurately, although they did not need to attend to the visual cue. All types of training were better than no training at all. Results are discussed in terms of the role of visual feedback in the development and assessment of programs for movement.     

Learning to Align Relations: The Effects of Feedback and Self-Explanation

Relational similarity connects superficially dissimilar objects and events. In 2 experiments, the ability to recognize and respond to similar relations was studied in children ages 3 to 5 with 2 comparison tasks. Children interpreted illustrated pictures that shared perceptual or relational aspects and then made 2 comparison choices and explanations of these choices. Results of Experiment 1 demonstrated that when given explicit feedback regarding the relations depicted in the pictures, children learned to respond quickly to this type of similarity in subsequent trials, which involved novel relations. In Experiment 2, the effect of re- explanation on relational understanding was examined. Children age 4.5 to 5 years, but not 3- to 4-year-olds, showed relational learning when asked to explain the experimenter's relational choice.

The Role of Student Processing of Feedback in Classroom Achievement

This study focused on students' processing of feedback during regular classroom instruction. Students in two high-school computer programming classes were observed and asked to give retrospective reports of their thoughts during feedback episodes. Feedback episodes consisted of the teacher explaining test answers to the class after her grading and returning tests to students. The data showed that students' attention to feedback on missed, but not on correct, items was significantly related to course achievement and that this relationship was moderated by content knowledge. A qualitative analysis of retrospective reports revealed the diversity of ways of processing feedback and suggested two mechanisms that led to withdrawal of attention to feedback. One was the student's perception that he or she could not understand feedback and the other was dwelling on the negative affect produced by making errors.     

The Role of Fidelity and Feedback in the Wraparound Approach

Wraparound approaches are being implemented with children in many mental health systems around the country. Evidence for the effectiveness of the wraparound approach, however, is limited. In addition, the degree to which wraparound interventions adhere to the principles of wraparound has rarely been assessed. We examined the influence of adherence to wraparound principles and outcome feedback within the wraparound approach. Children participating in family team meetings were enrolled in a feedback or no feedback condition. Teams receiving feedback were given a brief report regarding outcome progress four times over a three-month period. In addition, adherence to wraparound principles was assessed in the initial team meeting and examined in relationship to outcome at three months and nine months. Although youth in both feedback and non-feedback groups improved with intervention, there were few differences between the groups based on outcome feedback. Similarly, adherence was uniformly high and did not influence the outcome for individual cases. Although the wraparound approach was helpful for youth in our sample, outcome feedback and adherence to wraparound principles had limited influence on these effects.     

The Role of Task Experience and Prior Knowledge for Detecting Invalid Augmented Feedback while Learning a Motor Skill

Two hypotheses were investigated. These were generated from results reported by Buekers, Magill, and Sneyers (1994) and an uncertainty account of those and other effects on skill learning of erroneous knowledge of results (KR). The first hypothesis proposes that if experienced performers have developed the capability of detecting and correcting errors, then they should not be influenced by erroneous KR in the same way as novices. The second proposes that if information about the invalid feedback is given to subjects prior to the beginning of the practice trials, then the capability for assessing feedback can be accelerated such that subjects who receive this advance information should not be misled by the erroneous KR. The first hypothesis was investigated in Experiment 1 by having subjects practise an anticipation timing task for 450 trials. One group received correct KR on all trials, and another group received no KR. Half of the subjects in each group were unexpectedly switched to erroneous KR after 400 trials. Results indicated that the erroneous KR influenced both groups during acquisition and on a retention test one minute later. However, on a retention test given one week later, only the group that had practised with no KR before being switched to erroneous KR continued to show the negative influence of the invalid KR. The second hypothesis was examined in Experiment 2 by telling subjects prior to beginning practice trials that it was possible that the KR they received would be erroneous. Results showed that this intervention strategy was effective on the no-KR retention tests only for subjects who had no-KR trials alternated with trials on which they received the erroneous KR. The results of these experiments provide evidence that uncertainty about the validity of sensory feedback increases the likelihood that subjects will be misled by invalid augmented feedback. Moreover, this uncertainty can be overcome by increased experience or by providing advance knowledge about the nature of the invalid feedback.     

The Manager as Coach: The Role of Feedback Orientation

Purpose

This study investigated the consequences of manager feedback orientation in the manager-as-coach process. Integrating theories of feedback and coaching, we examined the extent to which manager feedback orientation was related to indicators of effective coaching and subordinate feedback orientation.

Design/methodology/approach

One hundred three manager–subordinate dyads participated in this study.

Findings

Managers who value feedback for themselves (high feedback orientation) were viewed as better coaches as assessed through employee perceptions of coaching behaviors, the coaching relationship, and the feedback environment. Manager feedback orientation was also related to subordinate feedback orientation, and this relationship was mediated by the coaching effectiveness indicators.

Implications

This study demonstrated that the coaching manager with higher feedback orientation is viewed as more effective than the coaching manager with lower feedback orientation. This study assesses previously untested theories of coaching and demonstrates the value of manager feedback orientation in the coaching process.

Originality/value

This is the first study to integrate the feedback and coaching literatures to test derived hypotheses regarding feedback orientation in the manager-as-coach framework.

     

Linking Failure Feedback to Individual Creativity: The Moderation Role of Goal Orientation

The sense-making theory of creativity is extended by identifying failure feedback as a process that shapes creative interpretations and actions. We also consider the moderating effect of goal orientation on the relationship between failure feedback and individual creativity, according to the sense-making theory. A 2-waves survey data from 345 R&D employees and their supervisors in five Chinese high-tech companies indicated: (a) supervisors’ failure feedback positively correlates with incremental and radical creative performance, (b) learning goal orientation strengthens the relationship between failure feedback and creativity, and (c) avoidance goal orientation attenuates the relationship between failure feedback and creativity. The findings suggest that goal orientations play roles in optimizing failure feedback effects on creativity outcomes.     

学习因素对语义信息加工性质的影响

本研究通过两个行为实验,采用句子核证作业,将SAD技术和范畴学习范式有机地结合起来,对语义信息加工进程以及学习因素在其中的作用进行了考察。实验一研究了熟悉性对语义信息加工的影响。结果表明,高熟悉句的部分信息积累具有离散的趋势;低熟悉句的部分信息积累是连续性的。实验二采用范畴学习。并结合SAD技术的句子核证作业．考察了在学习过程中语义加工性质的变化。结果发现：过度学习比初始学习有更多的部分信息积累,并随信号间隔的延长而逐渐增加;过度学习表现出部分信息积累的离散性变化;初始学习则表现出连续累积的趋势。说明学习确实造成了连续性加工向离散性质的过渡。

The Interaction of Criterion and Feedback Information in Learning a Drawing Task

Experiments were designed to examine the influence of criterion and feedback information in the learning of a two-dimensional drawing task. Experiment 1 showed that when the task criterion is well known to the subject, the combined presentation of criterion information and information feedback facilitates the rate of acquisition of the skill but not its overall performance level of achievement. Experiment 2 showed that when the task criterion information is not well known to the subject, presentation of criterion information facilitates both the rate of acquisition and the overall performance level and, furthermore, is essential if configuration information feedback is to be utilized effectively. Experiment 3 showed that it is the combined presentation of criterion and configuration information feedback, rather than the isolated presentation of either type of information alone, that facilitates learning and performance. Collectively, the findings from the three experiments suggest an interactive effect of prior knowledge by the learner and type of augmented information in facilitating the acquisition of skill, according to the constraints imposed in the task. The data are consistent with the proposal that the degrees of freedom in the information available to support motor skill learning must match the degrees of freedom to be constraint in the perceptual-motor workspace.     

Learning Under Conditions of Action Information Feedback

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied.     

Neurocognitive Contributions to Motor Skill Learning: The Role of Working Memory

ABSTRACT

Researchers have begun to delineate the precise nature and neural correlates of the cognitive processes that contribute to motor skill learning. The authors review recent work from their laboratory designed to further understand the neurocognitive mechanisms of skill acquisition. The authors have demonstrated an important role for spatial working memory in 2 different types of motor skill learning, sensorimotor adaptation and motor sequence learning. They have shown that individual differences in spatial working memory capacity predict the rate of motor learning for sensorimotor adaptation and motor sequence learning, and have also reported neural overlap between a spatial working memory task and the early, but not late, stages of adaptation, particularly in the right dorsolateral prefrontal cortex and bilateral inferior parietal lobules. The authors propose that spatial working memory is relied on for processing motor error information to update motor control for subsequent actions. Further, they suggest that working memory is relied on during learning new action sequences for chunking individual action elements together.     

Reduced-Frequency Concurrent and Terminal Feedback: A Test of the Guidance Hypothesis

In 2 experiments, the authors manipulated the frequency of concurrent feedback to discern the effects on learning. In each experiment, participants (N = 48, Experiment 1; N = 36, Experiment 2) attempted to reproduce a criterion force-production waveform (5 s in duration) presented on the computer monitor. Consistent with the guidance hypothesis, the results of Experiment 1 indicated very strong guiding effects of concurrent feedback and strong dependence on the feedback, as indicated by participants' extremely poor performance upon feedback withdrawal in retention. As predicted by the guidance hypothesis, dependence on the feedback was reduced as a result of reducing the frequency of the concurrent feedback. The results of Experiment 2 indicated that one can enhance learning by providing concurrent and terminal feedback on 1 trial, with no feedback on the subsequent trial. In that way, the strong guiding effects of concurrent feedback could be realized and the beneficial effects of terminal feedback could also be achieved.     

反馈干预对学习判断的影响

将反馈干预作为外部线索引入元记忆研究,采用重复学习任务,在第一轮次学习-测验之后插入反馈干预,用两个实验分别考查任务反馈和能力反馈两种形式下的反馈效价对第二轮次即时学习判断的影响.结果表明：①在学习过程中,学习者会进行自我监测;②在任务反馈形式下,反馈信息与自我监测信息冲突,导致反馈干预对元认知监测和认知过程没有影响;③在能力反馈形式下,反馈信息与自我监测信息的冲突消失,结果消极反馈影响了元认知监测.由此得出结论：只有在不与自我监测信息冲突的情况下,反馈干预才对学习判断产生影响.此外,在有反馈干预的情况下,两个实验中都出现了显著的练习伴随低估效应.
