Outcome Feedback Effects on Under- and Overconfident Judgments (General Knowledge Tasks)

Effects of outcome feedback on overconfident and underconfident judgments were investigated. It was hypothesized that outcome feedback had a twofold effect on confidence judgments, corrective and confidence increasing, the latter effect operating only when the items to be judged are related and/or nonindependent. The proposed hypothesis implies two predictions which were tested in two experiments: (1) If the items are nonindependent and related, outcome feedback will reduce bias and improve calibration of underconfident judgments; by contrast, the feedback will neither reduce bias nor improve calibration in the case of overconfident judgments. (2) If, on the other hand, the items are independent and unrelated, outcome feedback will reduce underconfidence as well as overconfidence bias and improve calibration in both cases. The obtained results provided strong support for the first prediction, while the second prediction was not supported. Although the differences between with- and without-feedback groups on the dependent variables were in the expected direction, they were nonsignificant.     

Three feedback methods in acquisition and retention of badminton skills

Comparison of three different feedback methods using information about the correct execution of the technique, errors of execution, and a combination of these on the acquisition and retention of two badminton skills of different difficulty were examined. Participants were 48 young male athletes, 10 to 14 years of age, with 2 to 4 years of training. They were divided into three equal groups and instructed on the long forehand serve, a more difficult serve than the short backhand. The first group received instructions for correct execution, the second group received instructional cues on errors of execution, and the third group received instructions on errors and how to correct them. The training program lasted 12 practice units. There was a pretest, a posttest after the end of the 10-wk. training program, and 2 wk. later, a retention test. A three-way (2 difficulty x 3 groups x 3 measures) analysis of variance with repeated measures on the last factor was applied to analyze scores with the three practice methods of corrective feedback for the two badminton skills. Analysis showed the group receiving correct technique information had increased scores on both skills. The group receiving information on errors increased their scores on the less difficult skill. The group receiving information on errors and correct technique increased their scores on the more difficult skill. Physical education teachers or coaches teaching skills to young participants should consider difficulty of skills and use appropriate corrective feedback for better acquisition and retention of sport skills.     

The effects of source and type of feedback on child witnesses' metamemory accuracy

This study investigated the effect of feedback on the accuracy (realism) of 12‐year‐old children's metacognitive judgments of their answers to questions about a film clip. Two types of judgments were investigated: confidence judgments (on each question) and frequency judgments (i.e. estimates of overall accuracy). The source of feedback, whether it was presented as provided by a teacher or a peer child, did not influence metacognitive accuracy. Four types of feedback were given depending on whether the participant's answer was correct and depending on whether the feedback confirmed or disconfirmed the child's answer. The children showed large overconfidence when they received confirmatory feedback but much less so when they received disconfirmatory feedback. The children gave frequency judgments implying that they had more correct answers than they actually had. No main gender differences were found for any of the measures. The results indicate a high degree of malleability in children's metacognitive judgments. Copyright © 2004 John Wiley & Sons, Ltd.     

EFFECTS OF VERBAL REGULATION AND AGE ON RULE ACQUISITION AND TRANSFER

The ability of 119 children (mean ages 6.2, 8.2, 10.1, and 12.3) to perform rule learning and subsequent transfer tasks was observed utilizing three experimental conditions: overt-verbal, covert-verbal, and control. The performance of the subjects suggests that the child who is forced to verbalize his conceptual strategies will reach criterion faster in the rule acquisition task, and will also be more successful in his attempts to transfer the acquired rule. With regard to the transfer tasks specifically, it was found that overt-verbal learning was significantly more effective than covert-learning, and that the covert-verbal condition yielded significantly higher scores than did the control condition. These results point to the effectiveness of verbal strategies in the acquisition and transfer of learning.     

Acquisition context and the use of causal rules

Judgmental asymmetries in using causal knowledge (e.g., for prediction or diagnosis) have been attributed to the inherent directionality of causal knowledge. The present study examines the effect of acquisition context--representations used for initial instruction, and the type of judgement required during acquisition--on judgments using causal rules. In contrast to traditional concept formation research, this paradigm examined the development of procedures for using rules, rather than rule induction. College-student subjects learned to use causal rules describing digital logic gates, receiving instruction with either verbal rules or truth tables, and practicing either predicting or verifying logic-gate outputs. After 200 trials of practice with each rule, subjects were transferred to the untrained judgment task. Transfer was strongly asymmetrical. Subjects trained to make prediction judgments were slowed substantially by transfer to the verification task, while subjects trained to make verification judgments had little difficulty with transfer to the prediction task. Truth-table representations resulted in superior performance, especially for verification judgments. Contrary to prediction, verification judgments always required more time. The results demonstrate that acquisition context may be partly responsible for judgmental asymmetries, and imply that examining conditions of acquisition is important for understanding how causal knowledge is used.     

Phonetic segmentation in prereaders: Effect of corrective information

This study is focused on the capacity of preliterate children to learn explicit phonetic segmentation. In Experiment 1, subjects were induced through examples to delete the initial consonant in consonant-vowel-consonant (CVC) utterances. Performance was very poor at the beginning of the test but large improvements were observed in 5-year-olds when corrective feedback was provided. Four-year-olds did not on the average show a similar effect of feedback, but when tested again in Experiment 2 with a free segmentation procedure the majority proved capable of decomposing CVC syllables into smaller units and also displayed significant transfer from the earlier experience. In Experiment 3, fresh groups of children, aged four and five, were tested for either initial or final consonant deletion with immediate feedback. Improvements were observed at both ages and for both manipulations, although performance on initial consonant deletion was poorer than on final consonant deletion. Most children as young as 4 years can thus learn new segmentation games quite rapidly. The finding is discussed in relation to the notion that phonetic analysis is an important stumbling block in reading acquisition.     

On the nature of children's judgments of linguistic features: Semantic relations and grammatical morphemes

Children's judgments of sentences were examined in 3-, 4-, and 5-year-olds in an effort to examine the relationship between children's use of various linguistic features and their judgments of these features in formal tasks. The sentences the children were asked to judge differed on the basis of features acquired gradually during the development of children's linguistic usage. The judgments made by the children did not appear related to the course followed in the acquisition of language usage, a finding that suggests that language acquisition and formal linguistic judgments may reflect different processes.     

Judgments of learning are significantly higher following feedback on relatively good versus relatively poor trials despite no actual learning differences

Studies have consistently shown that prospective metacognitive judgments of learning are often inaccurate because humans mistakenly interpret current performance levels as valid indices of learning. These metacognitive discrepancies are strongly related to conditions of practice. Here, we examined how the type of feedback (after good versus poor trials) received during practice and awareness (aware versus unaware) of this manipulation affected judgments of learning and actual learning. After each six-trial block, participants received feedback on their three best trials or three worst trials and half of the participants were made explicitly aware of the type of feedback they received while the other half were unaware. Judgments of learning were made at the end of each six-trial block and before the 24-h retention test. Results indicated no motor performance differences between groups in practice or retention; however, receiving feedback on relatively good compared to relatively poor trials resulted in significantly higher judgments of learning in practice and retention, irrespective of awareness. These results suggest that KR on relatively good versus relatively poor trials can have dissociable effects on judgments of learning in the absence of actual learning differences, even when participants are made aware of their feedback manipulation.     

The influence of rule availability and item similarity on metacognitive monitoring during categorisation

In four experiments, we examined the sources of metacognitive judgments during the categorisation of new items after the learning of old items was completed. In the rule condition, the categorisation rule was explicitly given to the participants during learning, while in the no-rule condition participants relied on feedback to infer category membership. In the transfer phase, two types of novel items were used: good and bad transfer items. Transfer items also differed in the level of similarity to their training pairs. In the rule condition, all types of transfer items were classified with high accuracy and confidence. In the no-rule condition, a dissociation between accuracy and confidence was revealed. Good transfer items were classified more accurately than bad transfer items, whereas similar items were classified with higher confidence than dissimilar items. The obtained results suggest the utilisation of two potential cues for metacognitive judgments: declarative knowledge if the correct rule is explicitly available, and item similarity if it is difficult to infer the correct rule from feedback.     

Does Narrative Feedback Enhance Children's Motor Learning in a Virtual Environment?

Augmented feedback has motivational and informational functions in motor learning, and is a key feature of practice in a virtual environment (VE). This study evaluated the impact of narrative (story-based) feedback as compared to standard feedback during practice of a novel task in a VE on typically developing children's motor learning, motivation and engagement. Thirty-eight children practiced navigating through a virtual path, receiving narrative or non-narrative feedback following each trial. All participants improved their performance on retention but not transfer, with no significant differences between groups. Self-reported engagement was associated with acquisition, retention and transfer for both groups. A narrative approach to feedback delivery did not offer an additive benefit; additional affective advantages of augmented feedback for motor learning in VEs should be explored.

Experience and validity of clinical judgment: The illusory correlation

Mental health experts often justify diagnostic and predictive judgments on the basis of “years of experience” with a particular type of person. Justification by experience is common in legal settings, and can have profound consequences for the person about whom such judgments are made. However, research shows that the validity of clinical judgment and amount of clinical experience are unrelated. The role of experience in learning varies as a function of what is to be learned. Experiments show that learning conceptual categories depends upon: (1) the learner's having clear hypotheses about the possible rule for category membership prior to receiving feedback about which instances belong to the category, and, (2) the systematic nature of such feedback, especially about erroneous categorizations. Since neither of these conditions is satisfied in clinical contexts in psychology, the subsequent failure of experience per se to enhance diagnostic or predictive validity is unsurprising. Claims that “I can tell on the basis of my experience with people of a particular type (e.g., child abusers) that this person is of that type (e.g., a child abuser)” are simply invalid.     

The role of conceptual recoding in reducing children's retroactive interference

Reductions in children's retroactive interference were examined with conceptual recoding. Children learned two 10-item lists of toys; items on the 2nd list could also be classified as vehicles. Some children were not told about this 2nd category, whereas others were told either at the end of acquisition or just prior to the retention test 24 hr later. The results showed that (a) children benefited from the recoding instruction, (b) younger but not older children failed to benefit from the recoding manipulation when it occurred just prior to the retention test, and (c) recoding reduced retroactive interference primarily through affecting storage processes. These results provide new evidence concerning the importance of making information distinctive in storage in children's retention.     

Motor skill acquisition and retention as a function of average feedback, summary feedback, and performance variability

Summary feedback involves withholding feedback from subjects until the last trial in a block is completed, and then presenting feedback about each trial. A variation of this method, called average feedback (Young & Schmidt, 1992), presents subjects with only the mean of the trial block. We investigated whether these methods have similar effects on acquisition and retention of a simple motor skill. Five groups of subjects (n = 16 per group) performed 60 acquisition trials of an aiming task involving both spatial and temporal accuracy. We presented average and summary feedback based on either 5-trial blocks or 15-trial blocks and compared these schedules with every-trial feedback. During acquisition, all groups improved with practice, with a slight tendency for the every-trial condition to have less absolute error than the longer summary and average conditions. Analysis of delayed no-feedback retention tests, however, revealed a strong advantage for the 5-trial summary and average conditions compared with the every-trial condition. In addition, we found that for long blocks of acquisition trials without augmented feedback, the performance variability of those trials was associated with retention performance. Results are discussed in terms of how these different manipulations may make feedback less useful during acquisition, but foster the use of certain information processing activities that enhance overall learning.     

The effect of feedback training on distance estimation in virtual environments

It is often noted that distances are significantly underestimated in computer‐simulated (virtual) environments. Two experiments examine observers' ability to use error corrective feedback to improve the accuracy of judgments of egocentric and exocentric distances. In Experiment 1, observers viewed objects in an immersive virtual environment and estimated their distance through a blindfolded walking task. Different groups received feedback on either egocentric, exocentric or none of these judgments. Receiving feedback improved observers' ability to estimate only those distances for which feedback was provided. These effects persisted for at least 1 week. In Experiment 2, observers estimated egocentric distance by means of both a direct and indirect walking task. Receiving feedback on the direct walking task predominantly improved direct estimates and not indirect estimates. These findings suggest that although feedback training offers a relatively straightforward and immediate way of overcoming problems of distance estimation, its effects are specific to both the type of judgment and the type of response.

The Meaning of Brand Names to Children: A Developmental Investigation

We explored the way that children use brand names in making consumer judgments. Brand names can serve as a simple perceptual cue that identifies a product as one people are familiar with or one they associate with certain perceptual features. Brands can also be associated with symbolic or conceptual meanings, conveying status, prestige, or trendiness. We proposed that young children relate to brands on a perceptual level, whereas older children relate to brands on a conceptual basis as well. We examined this proposition in an experiment conducted with children 8,12, and 16 years of age. Participants were asked to evaluate an advertised product (e.g., athletic shoes) with a familiar brand name that was either popular (e.g., Nike^®) or less popular (e.g., Kmart^®). The advertised product was physically identical in both cases, allowing us to explore whether the brand name had meaning for children apart from its name familiarity or perceptual features. The use of conceptual brand meanings was assessed by asking participants to make several types of brand‐related judgments including evaluations of the advertised product, impressions of the owners of the advertised product, and evaluations of possible extensions of the popular brand name advertised. Results indicate that by the time children reach 12 years of age, they use brand names as an important conceptual cue in consumer judgments.     

Effect of simultaneous model observation and self-modeling of volleyball skill acquisition

This study examined the effect of feedback with simultaneous skilled model observation and self-modeling on volleyball skill acquisition. 53 pupils 12 to 15 years old formed two experimental groups and one control group who followed an intervention program with 12 practice sessions for acquisition and retention of how to receive a ball. Groups received different types of feedback before and in the middle of each practice session. Reception performance outcome (score) and technique in every group were assessed before and at the end of the intervention program and during the retention phase. A 3 (Group) x 3 (Measurement Period) multivariate analysis of variance with repeated measures was applied to investigate differences. Results showed equivalent improvement in all three groups at the end of the intervention program. In conclusion, types of augmented feedback from the physical education teacher are effective in acquisition and retention of the skill for reception in volleyball.     

On the Road to Self-Perception: Interpretation of Self-Behaviors Can Be Altered by Priming

ABSTRACT In 3 experiments, some participants read a story describing ambiguously mean behaviors performed by another person. Other participants read the story and imagined that they performed the behaviors. Results showed that (a) exposure to a conceptual priming manipulation caused assimilation effects in actor meanness judgments, regardless of whether the actor was self or other, (b) tasks designed neither to heighten self-concept accessibility nor to threaten the self moderated the effects of conceptual meanness primes on self-meanness judgments, and (c) this lack of moderation occurred despite considerable evidence of self–enhancement effects elsewhere in self-judgments. A fourth experiment examined the extent to which priming affected interpretations of real self or other behavior. Results were consistent with the idea that priming altered event interpretation and subsequent judgments but also suggested that judgments were influenced by self-enhancement motivation. Implications of the results for theorizing in personality and self-knowledge acquisition are discussed.     

Imagery ability and the acquisition and retention of movements

In this study, we examined the relationship between imagery ability, as measured by the Movement Imagery Questionnaire (MIQ), and the acquisition, retention, and reacquisition of movements. Based on their MIQ scores, 10 subjects were selected for the following imagery groups: high visual/high kinesthetic (HH), high visual/low kinesthetic (HL), and low visual/low kinesthetic (LL). The subjects learned four movements to a criterion level. Before each trial, subjects kinesthetically imaged the movement about to be produced. Following each acquisition trial, subjects were provided visual feedback. The acquisition phase was followed by a 2-day retention interval, a retention test consisting of three trials on each movement (no feedback provided), and a reacquisition phase. The HH group acquired the movements in the least number of trials, the LL group required the greatest number of trials, and the HL group required an intermediate number of trials. The data for the reacquisition phase showed the same trend. There was only weak evidence for a relationship between imagery ability and the retention of the movements. These findings support the position that high imagery ability facilitates the acquisition, but probably not the short term retention, of movements.
