Does Feedback Improve the Accuracy of Recurrent Judgmental Forecasts?

Feedback has been shown to be a useful tool for improving decision making (Balzeret al.,1992) and might also be a useful tool for improving the accuracy of recurrent judgmental forecasts. The objective of this study was to examine the impact of feedback on accuracy when forecasting time series with structural instabilities. We found that task information feedback (prompting on the underlying structure of the time series) gave significantly better forecasting performance than performance outcome feedback (prompting with graphical indicators of forecasting accuracy or prompting words expressing levels of forecasting accuracy). We also found that adding cognitive information feedback (prompting on desirable forecasting behaviors) to task information feedback did not significantly improve forecasting performance. Task information and task information feedback with added cognitive information feedback, but not performance outcome feedback, were superior to the baseline of providing simple outcome feedback (following each forecast with the actual value of the time series).     

The Effects of Stimulus Medium and Feedback on the Judgment of Rapport

The efficacy of cognitive feedback and the relative ineffectiveness of outcome feedback has been well documented in the judgment literature (Balzer, Doherty, & O′Connor, 1989). The relevant research leading to this conclusion, however, has been characterized by artificially constructed tasks with rigidly controlled stimulus properties which may not be representative of many real-world ecologies. The present study examined the effects of one form of cognitive feedback, task information, and outcome feedback in such an in vivo setting, that is, on a task which required subjects to make inferences about the level of rapport present in videotaped real-life social interactions. The two types of feedback were also compared on a second task involving a simplified, quantified, graphical representation of the relevant cues that had been extracted from the video display. Results from the graphically presented displays replicated earlier findings supporting the superiority of cognitive feedback. Results from the video display, however, showed exactly the opposite: outcome feedback here was superior to cognitive feedback in increasing performance accuracy.     

How am I doing? Performance feedback mitigates the effects of mental fatigue on endurance exercise performance

Mental fatigue induced by an earlier cognitive task can impair performance on a subsequent physical task. The current study investigated whether such performance impairment could be mitigated by performance feedback. In an experimental sequential-task design, 63 sport science students completed a series of three tasks: 5-min physical (pre-test), 20-min cognitive, 5-min physical (post-test). Participants were randomly allocated to one of three groups: feedback (n = 23), no feedback (n = 20), control (n = 20). The physical tasks, which assessed force production during a self-paced rhythmic handgrip task as a measure of physical endurance performance, were performed with (feedback group) or without (no feedback group, control group) visual performance feedback. The cognitive tasks involved either completing a 2-back memory task to induce mental fatigue (feedback and no feedback groups) or watching a didactic film (control group). Self-report measures (fatigue, exertion, vigor, motivation) were collected throughout. The 2-back cognitive task increased mental fatigue, mental exertion and general fatigue in the feedback and no feedback groups compared to the control group. Relative to the pre-test physical task, post-test endurance performance declined in the no feedback group (−14.4%) but did not change in the control (−2.6%) and feedback (−2.4%) groups. This mitigation of performance effect was not accompanied by parallel changes in fatigue, exertion, vigor, or motivation. In conclusion, visual performance feedback mitigates the negative effects of mental fatigue on physical endurance performance.     

Optimism, pessimism, and false failure feedback: Effects on vigilance performance

Following the logic of a prior experiment (Seligman et al., 1990) with varsity collegiate swimmers, sixty student volunteers performed a brief, but highly stressful vigilance task. Half were then given false feedback indicating poor performance; the others experienced a non-evaluative display at that point. All were then asked to repeat the vigil. Half the observers were assessed as high optimists and half as high pessimists. The pessimists showed a steeper vigilance decrement than the optimists, consistent with a model (Scheier and Carver, 1987) that proposes that pessimists are more emotion-focused under stress than optimists, and hence would be less attentive to the vigilance display, regardless of feedback condition. The false negative feedback actually turned out to be ineffective; hence, based on Seligman's account of the swimmer study, which requires effective negative feedback, there should have been no vigilance performance difference between optimists and pessimists, either pre- or post-feedback.

Moderating Effects of Processing Objective,Question Order and Delay on Memory and Judgement

The performance appraisal process makes many demands on a manager's cognitive abilities as there are a number of competing requirements. For instance, recalling performance information after a long period of time, determining training needs, ascertaining future objectives, etc. The processing objective present at the time of observation may also influence whether evaluations are made ‘on-line’ or are ‘memory-based’. Some research has found that the rating instrument may moderate memory and judgement by making certain information salient (Ilgen, Barnes-Farrell, and McKellin 1993; Lichtenstein and Srull 1987; Woehr and Feldman 1993). While some studies have investigated both rating and recall order and processing objective, none have investigated both of these factors in relationship to time delay and the influence of impressions that were not directly related to performance. It has been suggested that the tendency to recall impressions of others rather than specific behaviour that lead to these impressions increase over time (DeNisi, Cafferty and Meglino 1984; Kozlowski and Ford 1991; Murphy and Balzer 1986). This study sets out to examine the influence of three variables, information processing objective, order of recall and rating and time delay on the relationship between memory and judgement and the various models important to these processes (DeNisi, Cafferty and Meglino 1984; Woehr and Feldman 1993; Hastie, Park and Weber 1984; Williams, Cafferty and DeNisi 1990). The experiment was a 2 × 2 × 2 between subjects factorial design with three independent variables with 187 students from various disciplines. Support was found for the model of performance appraisal by DeNisi et al. (1984) in that overall evaluations influenced dimensional ratings when a time delay was introduced. However, the hypothesized effect of recall/rating order was in the opposite direction to that expected, indicating that there were additional factors that influenced the relationship between memory and judgement.     

An individual differences approach to the halo-accuracy paradox

In performance appraisal, the halo-accuracy paradox describes the surprising result that rater accuracy can be positively correlated with the halo rating error. Fisicaro (1988) provided an explanation for this unlikely relationship by proposing an inverse V function as the relationship between accuracy and invalid halo in which maximum accuracy is located at zero invalid halo. This paper develops the model by proposing that maximum accuracy does not have to be at zero invalid (Hypothesis 1). As the cognitive difficulty of a rating task increases, a negative monotonie relationship between maximum achievable accuracy and associated value of absolute invalid halo is specified (Hypothesis 2). The hypotheses were tested in two different experimental situations. Results from both studies supported Hypothesis 1 but, whilst a distinct pattern between accuracy and absolute invalid halo was noted, only a weak version of Hypothesis 2 could be supported. The evidence from this paper demonstrates that the halo-accuracy paradox is not an artefact as some recent reviewers have proposed (Balzer & Sulsky, 1992; Murphy & Balzer, 1989; Murphy & Cleveland, 1991).     

Cognitive underpinnings of contextual interference during motor learning

The reported study examined the cognitive processes underlying contextual interference (CI) in motor learning. This experiment was designed to assess the combined influence of practice schedule (blocked or random) and task similarity (similar or dissimilar) on acquisition and retention performance. Participants (N = 60) learned a set of three variations of a timing task according to a similar (900, 1000 and 1100 ms) or dissimilar parameter condition (700, 1000 and 1300 ms) with either a blocked or random practice order: this resulted in 4 experimental groups. Performance in delayed retention demonstrated a typical CI effect due to the schedule of practice for the dissimilar parameter condition with the random practice group outperforming the blocked practice group. Conversely, no blocked-random difference was found for the similar parameter condition. These findings lend support for the reconstruction hypothesis by showing that supplementing random practice with additional intertask elaboration (i.e., similar parameter condition) did not facilitate subsequent retention performance.     

The Effects of Self-Esteem,Task Label,and Performance Feedback on Task Liking and Intrinsic Motivation

Abstract

American undergraduate students' task liking and intrinsic motivation were examined using 2 × 2 × 2 (Self-Esteem × Task Label × Feedback) analyses of variance. Identical tasks were labeled as either difficult or easy, and bogus performance feedback was given randomly to each subject. For subjects with high self-esteem, feedback had strong impact on their liking of a difficult task, whereas for those with low self-esteem, feedback had strong impact on liking of an easy task. After positive feedback for performing a difficult task, subjects with high self-esteem increased task liking, whereas those with low self-esteem decreased task liking. Subjects also showed higher intrinsic motivation after positive feedback than after negative feedback.     

Information elaboration and team performance: Examining the psychological origins and environmental contingencies

Information elaboration enables functionally diverse teams to transform their breadth of knowledge resources into actionable solutions to complex problems. The current study advances information elaboration theory and research in two ways. First, we identify how team ability and social motivation composition characteristics provide the psychological origins of complex information processing efforts. Second, we identify environmental turbulence as an important boundary condition, clarifying when information elaboration benefits team performance and when it does not. These ideas were tested in a sample of 4-person self-managed teams (N = 68) which were functionally diverse and performed a cooperative strategic decision-making task. Results indicate that cognitive ability equips teams with the “can do” ability for complex elaboration efforts through emergent team mental models, whereas low preferences for self-reliance provide the “will do” motivation for in-depth information exchange through collective leadership. In turn, teams benefited from information elaboration in turbulent but not stable environments.

Baboons, like humans, solve analogy by categorical abstraction of relations

Reasoning by analogy is one of the most complex and highly adaptive cognitive processes in abstract thinking. For humans, analogical reasoning entails the judgment and conceptual mapping of relations-between-relations and is facilitated by language (Gentner in Cogn Sci 7:155–170, 1983; Premack in Thought without language, Oxford University Press, New York, 1986). Recent evidence, however, shows that monkeys like “language-trained” apes exhibit similar capacity to match relations-between-relations (Fagot and Thompson in Psychol Sci 22:1304–1309, 2011; Flemming et al. in J Exp Psychol: Anim Behav Process 37:353–360, 2011; Truppa et al. in Plos One 6(8):e23809, 2011). Whether this behavior is driven by the abstraction of categorical relations or alternatively by direct perception of variability (entropy) is crucial to the debate as to whether nonhuman animals are capable of analogical reasoning. In the current study, we presented baboons (Papio papio) and humans (Homo sapiens) with a computerized same/different relational-matching task that in principle could be solved by either strategy. Both baboons and humans produced markedly similar patterns of responding. Both species responded different when the perceptual variability of a stimulus array fell exactly between or even closer to that of a same display. Overall, these results demonstrate that categorical abstraction trumped perceptual properties and, like humans, Old World monkeys can solve the analogical matching task by judging the categorical abstract equivalence of same/different relations-between-relations.     

Team Mental Models,Team Goal Orientations,and Information Elaboration,Predicting Team Creative Performance

This study aimed to enhance understanding of team creativity by investigating the type of team mental models that team members develop during their work on a creative problem solving task. We hypothesized that teams that develop dissimilar team mental models, compared to similar and complementary team mental models, will achieve a higher information elaboration. This effect will be moderated by the development of a high learning-performance team goal orientation. Information elaboration in turn was hypothesized to predict team creative performance. In a 3 (similar/dissimilar/complementary team mental models) × 3 (learning/performance/learning-performance goal orientation) experimental study on a sample of 33 teams (N = 98) we found that teams that developed more dissimilar team mental models and experienced a learning-performance goal orientation intervention engaged in more information elaboration. Information elaboration, in turn, mediated the relationship between the interaction between team mental models and team goal orientations and team creative performance. Implications for research on team mental models and team creativity are discussed.     

Reducing cognitive complexity in a hypothetico-deductive reasoning task

The confusion/non-consequential thinking explanation proposed by Newstead, Girotto, and Legrenzi (1995) for poor performance on Wason's THOG problem (a hypothetico-deductive reasoning task) was examined in three experiments with 300 participants. In general, as the cognitive complexity of the problem and the possibility of non-consequential thinking were reduced, correct performance increased. Significant but weak facilitation (33-40% correct) was found in Experiment 1 for THOG classification instructions that did not include the indeterminate response option. Substantial facilitation (up to 75% correct) was obtained in Experiment 2 with O'Brien et al.'s (1990) one-other-THOG classification instruction. In Experiment 3, a revised version of O'Brien et al.'s pre-test problem format also led to substantial facilitation, even with the use of the standard three-choice THOG classification instruction. These findings are discussed in terms of Newstead et al.'s theoretical proposal and possible attentional factors.     

Cognitive-style differences in belief persistence after evidential discrediting

Cognitive-style differences in belief persistence were investigated in a debriefing paradigm by comparing the reactions of field-dependent and field-independent persons to the total evidential discrediting of their beliefs. Ss were exposed to apparent success or failure experiences via false performance feedback on a novel discrimination task. Following a debriefing procedure which revealed the bogus nature of the feedback. Ss estimated their actual performance and ability at the task. The results showed that belief persistence after evidential discrediting was greater for field dependents than for field independents. Explanations of the findings based on dissonance-reduction mechanism and disbelief in the discrediting were discussed, but the preferred interpretation of the results involved differences in cognitive re-structuring as a function of cognitive style.     

Biofeedback and reinforcement to increase heterosexual arousal in homosexuals

Relatively few procedures exist for developing heterosexual arousal in the treatment of sexual deviation (Barlow, 1973) although several recent studies suggest this is a necessary component of treatment (Feldman and MacCulloch, 1971; Bancroft, 1970; Barlow, 1974).In recent years, biofeedback techniques have been applied to many types of disorders (Blanchard and Young, 1974). Basic to biofeedback technology is the notion that providing a person with feedback (or immediate information) of a bioelectric response enables him to learn (gain) self-control of that response. These responses traditionally have been considered involuntary and include heart rate (Scott et al., 1973a). blood pressure (Benson et al., 1971), stomach acid pH (Welgan. 1972), and electroencephalographic activity (Sterman, 1972), In the present experiments, biofeedback and its attendant technology was applied to the problem of generating heterosexual arousal in homosexual males.Frequently, in biofeedback research, reinforcement has been used in addition to feedback in attempting to teach self-control of a response. In fact, an alternate way of conceptualizing and describing the biofeedback research is in terms of operant conditioning (e.g., Weiss and Engel, 1971: Scott et al., 1973b). In one sense, however, feedback and reinforcement are inextricably confounded: the delivery or non-delivery of a reinforcer provides the S with information about the rightness or wrongness of his response and hence, binary feedback about it. Likewise, if feedback or knowledge of whether the response has reached a criterion level or not is effective in leading to a change in the response, then feedback functions as a reinforcer. Reinforcement, however, may be viewed as providing both information about the response (feedback) plus an incentive to change it in the desired direction in addition to any incentive provided by successful performance of a task. Thus, if one provides Ss with a separate, functionally defined reinforcer in such a way that no additional information about the response is conveyed, it becomes possible to detect additive effects of reinforcement over feedback effects. Such was the second purpose of this study.Several recent analogue experiments with volunteers have reported success in modifying erections through feedback and/or reinforcement. Price (1973) found that heterosexual volunteers who received analogue visual feedback as well as binary feedback, provided by a colored light once the needle had passed a pre-set criterion, showed a shorter latency to peak erection and maintained criterion erection longer than a control group receiving no feedback. Both groups were listening to erotic audio tapes. Rosen (1973) demonstrated significant suppression of tumescence in a group of heterosexual volunteers provided with response contingent signal lights. A group receiving non-contingent feedback did not show this effect. In a technical paper, Laws and Pawlowski (1973) have suggested audio feedback of tumescence as a treatment for deficits in sexual arousal.In the clinic, Harbison, Quinn and McAllister (1970), in an uncontrolled case study, reported increasing heterosexual responsiveness in homosexuals through reinforcement of erection. In one of their homosexual patients they were able, over a long series of trials, to increase erection to a heterosexual stimulus (female slide) through rewarding progressively larger responses with sips of iced lime after the patient was water deprived. In addition to the reinforcement, this S was given feedback, of sorts, in that a light was flashed for each successful trial. A second homosexual patient was similarly rewarded for maintaining progressively longer and clearer fantasies of heterosexual behavior. Since other treatments were also applied and no experimental analysis was performed, it is not possible to evaluate the effectiveness of the procedure.In the present experiment the separate effects of feedback and reinforcement to increase heterosexual arousal in homosexuals was experimentally evaluated using single case experimental design methodology (Barlow and Hersen, 1973). Since each experiment was somewhat different in design and purpose, each will be described separately.     

Depression and selection of positive and negative social feedback: motivated preference or cognitive balance?

In this commentary we examine Swann, Wenzlaff, Krull, and Pelham's (1992) findings with respect to each of 5 central propositions in self-verification theory. We conclude that although the data are consistent with self-verification theory, none of the 5 components of the theory have been demonstrated convincingly as yet. Specifically, we argue that depressed subjects' selection of social feedback appears to be balanced or evenhanded rather than biased toward negative feedback and that there is little evidence to indicate that depressives actively seek negative appraisals. Furthermore, we suggest that the studies are silent with respect to the motivational postulates of self-verification theory and that a variety of competing cognitive and motivational models can explain Swann et al.'s findings as well as self-verification theory.     

Calibration of sensory and cognitive judgments: Two different accounts

The purpose of this study was to test predictions of two recent theories of realism of confidence. Ecological approaches to realism of confidence in one's general knowledge (Gigerenzer et al. , 1991; Juslin, in press a ; Björkman, in press) predict good calibration or, in the case of poor cognitive adjustment, overconfidence, within the cognitive domain. The subjective distance theory of confidence in sensory discriminations (Björkman et al. , 1992) predicts a pervasive underconfidence bias for sensory discriminations. Empirical data are reported showing that: (a) Calibration for sensory judgments is considerably poorer than calibration for well adapted cognitive judgements, a difference that can be entirely traced to underconfidence in the sensory domain. (b) While an initial overconfidence bias in the cognitive domain is removed by outcome feedback, the bias observed in sensory discriminations is unaffected even by a prolonged feedback session. It is suggested that the nature of confidence in sensory discriminations is different from the nature of confidence in cognitive judgments.     

The effect of feedback sign on task performance depends on self-concept discrepancies

Control theories claim that information about performance is often used by multiple goal systems. A proposition tested here was that performance information can create discrepancies in self-concept goals, directing cognitive resources away from the task goal system. To manipulate performance information, 160 undergraduates were given false positive or false negative normative feedback while working on a task that did or did not require substantial cognitive resources. Half of the participants were then given an opportunity to reaffirm their self-concepts following feedback, whereas half were not. Feedback sign positively related to performance only for those working on the cognitively intense task and not given a chance to reaffirm. Otherwise, feedback sign was negatively related to performance, albeit weakly.
