Self-focused attention and belief perseverance

The perseverance of an erroneous belief was investigated in the debriefing paradigm as a function of self-focused attention. Subjects were given either success or failure experiences via bogus performance feedback and received this feedback under high or low mirror self-focusing. All subjects were subsequently debriefed about the false nature of the feedback, and then, before answering questions about their estimated actual performance and ability, mirror self-focus was again manipulated. The results showed that self-focus prior to debriefing increased belief perseverance while self-focus after debriefing reduced the perseverance effects. Discussion of these findings emphasized the role of self-focus in information processing before and adherence to veridical standards after debriefing.     

Learned helplessness and IQ differences

Two groups of adult Ss differing in verbal IQ were compared in a learned helplessness experiment involving cognitive tasks and non-contingent rewards. The mean IQs for the two groups were 131 and 117. As predicted, the higher IQ Ss performed better overall and showed greater awareness of the response-outcome contingency. Their test-task performance was also more affected by the contingency manipulation although this occured only with success feedback. Implications of the results for cognitive accounts of human helplessness are discussed.     

Anxiety and cognitive-task performance

The performance of individuals high and low in trait anxiety was compared on a cognitive task involving letter transformation. This task was performed in the presence or absence of monetary incentive for superior performance. Adverse effects of anxiety on performance were apparent only on the more complex versions of the letter-transformation task. Analysis of the microstructure of the task indicated that anxiety impaired the rehearsal and storage of task-relevant information. Motivation in the form of monetary incentive improved the performance of low-trait-anxiety Ss, but had no effect on high-trait-anxiety Ss. The findings were discussed with reference to the working memory system and the theory proposed by Eysenck (1979).     

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.     

Informational and motivational components of social reinforcement

Thirty-six four-year-old children of each sex were tested in a two-choice marble dropping task. There were three Ss in each cell of a 3 × 2 × 2 × 2 factorial design. The factors investigated were: reinforcement condition (Contingent, Yoked, Nonreinforcement), sex, base preference level (strong vs weak), Base Rate Level (high vs low). The dependent variables were: base preference ratio, base rate, preference ratio change, rate change. The contingently reinforced Ss had significantly higher preference change scores than Ss in the other two reinforcement conditions but only at the high base preference level. The Ss in both the contingent and yoked groups had higher rate change scores than Ss in the nonreinforcement group. The results were interpreted as indicating social reinforcement may have two effects, one a cue function and the other an effect on S's motivational system. The results indicate that regression effects do not operate in the two-choice task and that crossing baseline levels of performance is an effective way to control baseline differences in analyses of change in the two-choice task.     

A developmental study of differences in initial coding and recoding of hypothesis information

Coding and recoding of hypothesis information was studied in children in Grades 3, 5, and 7, and college students. Each S was tested on several two-choice discrimination problems. A problem consisted of two trials, a training trial and a test trial. The information available for coding on the first trial was varied in three series of problems by using pairs of stimuli differing in 3, 4, or 6 dimensions. Recoding after an error was facilitated in half of the problems in each series by allowing the stimuli to persist briefly after response and feedback. The stimuli terminated immediately after response and feedback in the remaining problems. The second trial of a problem, in which the stimuli differed on only one dimension, was used to probe for the information coded or recoded on the first trial. On the average, fewer dimensions were coded per trial by the younger Ss than by the older Ss. Neither the effects of negative feedback nor the effects of stimulus persistence were found to be related to developmental level. It was concluded that a deficiency in young children's ability to code, but not recode, hypothesis information contributes to their less efficient performance in discrimination problems.     

Effects of the temporal relationship of feedback and stimulus information upon discrimination-learning strategies

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. In one condition (/+3) feedback was delivered immediately upon S's response while the stimuli were still in view. In another (/0) feedback was also immediate but stimuli were extinguished immediately upon S's response. In the third condition (/?3), stimuli were extinguished immediately upon response and feedback was delayed 3 sec. Major findings among the children were (a) Ss of all conditions coded information at the same (high) average efficiency, (b) Ss of conditions /0 and /?3 recoded with significantly less efficiency than those of /+3, and (c) Ss in condition /+3 manifested primarily efficient information-processing strategies, those in condition /0 showed intermediate performance, and those of condition /?3 showed relatively primitive stereotyped behavior. Among adult Ss performance was uniformly high with little effect on any response measure investigated.     

Prospective Examination of Leisure-Time Exercise Behavior During Pregnancy

The negative and positive content of self-talk, the relationship of self-talk to performance, and persistence following positive and negative feedback were investigated across different cultural backgrounds (European Americans n = 54, East Asians n = 26). East Asians had a significantly larger proportion of negative to positive self-talk than European Americans, d = .62. The greater proportion of negative self-talk related to poorer performance for European Americans, but better performance for East Asians, r ² = .13. European Americans’ practice persistence increased after receiving positive versus negative feedback, d = .59. No differences occurred in persistence for East Asians, d = .06. Results suggest sport psychology consultants and coaches should consider an athlete's cultural background when employing cognitive interventions and providing feedback.     

The assessment of subjective probability distributions: A training experiment

For this experiment 22 Ss were especially trained to assess subjective probability distributions for proportions concerning student characteristics. Two different assessment techniques were used. There were four experimental sessions. From the second session on, Ss received feedback about their performance in the previous session(s). While Ss' associated by far too much confidence with their assessments at the beginning, they learned to assess more realistic distributions. Furthermore, discrepancies between techniques were reduced.Some considerations for a more effective training procedure are made and the concept of giving feedback only according to the tightness of the assessed distribution is critically discussed.     

The developmental relationship between identity and equivalence conservation

Hooper's (1969a) finding that identity conservation develops prior to equivalence conservation was investigated using a more stringent within-subject design. Seventy-two kindergarten, first, and second graders were given three conservation tasks: (1) Identity, (2) Equivalence 1, in which the perceptual cues were comparable to those in Identity, and (3) Equivalence 2, the traditional Piagetian conservation task. Each task was administered under two levels of transformation. No significant differences in performance as a function of level of transformation, type of equivalence task, or sex of S were found, but first and second grade Ss performed better than kindergarten Ss. Eighty-six percent of the sample conserved in an all-or-none fashion, and 7 Ss (10%) passed equivalence while failing identity, thus contradicting the developmental priority of identity conservation.     

Development of relational learning: Effects of instruction and delay of transfer

Preschool children were trained on a color relevant oddity problem by one of three methods: increased salience of the oddity relationship, instruction on the solution rule, or a combination of increased salience and rule instruction. The youngest Ss solved the training problem when the solution rule was provided but not under the salience procedure. The two older groups solved in all conditions and errors decreased with age. The generality of the solution was determined by performance on a form relevant transfer task. The youngest Ss made fewer errors on the transfer problem following rule instruction training than following training in the combined procedure. The intermediate age group made fewer errors when the transfer task was administered one week after training than one minute after training. The transfer problem was easily solved by the oldest Ss and performance was independent of training procedure and amount of delay. These results were interpreted as reflecting developmental differences in relational concept learning.     

Effects of Cognitive Feedback Components,Display Format,and Elaboration on Performance

Balzer, Sulsky, Hammer, and Sumner (1992) demonstrated that task information, rather than cognitive information or functional validity information, is the necessary component of cognitive feedback (CFB). We designed a laboratory experiment to replicate the effects of (CFB) components while jointly investigating the impact of CFB display format and CFB elaboration on performance. Undergraduates (N = 323) were each randomly assigned to a single experimental condition in a 4 × 2 × 2 factorial design which manipulated the CFB components (TI, CI, TI + CI, or TI + CI + FVI), CFB display format (alphanumeric or graphic), and CFB elaboration (typical or augmented). The experimental task, procedures, and dependent measures were identical to Balzer et al. (1992). A main effect of CFB components was found, with results replicating the Balzer et al. findings that task information was necessary for improved performance. The main effects of CFB display format and CFB elaboration, as well as their interactions with each other and the CFB components, had little impact on judgment performance or reactions to feedback. Practical implications of the findings are discussed.     

Cognitive costs of encoding novel natural activities: Can “learning by doing” be distracting and deceptive?

Findings from action memory research suggest that the enactment of simple actions and naturalistic activities results in similar memory performance to that from their observation. However, little is known about potential differences between the conditions during the encoding of the to-be-studied actions and activities. We analysed the cognitive costs of encoding two novel naturalistic activities studied via enactment or via observation in four experiments. In addition to memory performance, we measured objective cognitive costs with a secondary task and subjective cognitive costs with repeated ratings of mental effort and estimates of general activity difficulty. Memory performance was comparable across study conditions throughout all experiments. The enactment of activities repeatedly resulted in slower reaction times in the secondary task than did observation, suggesting higher objective costs. In contrast, subjective costs were rated lower after enactment than after observation. Findings from a pantomimic enactment condition suggested that the low ratings of subjective costs after enactment represent a misinterpretation of task demands. Our findings imply that the widespread belief about “learning by doing” as an easy way of learning does not stem from an actual advantage in memory performance, but rather from continuous feedback about one's performance resulting from enactment.     

Cognitive processing and motor execution in the lexical decision task: a developmental study

We investigated lexical decision making in children and adults by analyzing spatiotemporal characteristics of responses involving a hand movement. Children’s and adults’ movement trajectories were assessed in three tasks: a lexical decision task (LDT), a pointing task that involved minimal cognitive processing, and a symbol task requiring a simple binary decision. Cognitive interference on motor performance was quantified by analyzing movement characteristics in the LDT and symbol task relative to the pointing task. Across age groups, movements in the LDT were less smooth, slower, and more strongly curved to the opposite response option, and these interference effects decreased steadily with age. Older children showed stronger interference effects than did adults, even though their reaction times were similar to adults’ performance. No comparable effects were found in the symbol task, indicating that task characteristics such as response mapping and decision selection alone are not able to explain the developmental differences observed in the LDT. Our results indicate substantial overlap between cognitive processing and motor execution in the LDT in children that is not captured by computational models of visual word recognition and cognitive development.     

Effects of personality and situational variation in locus of control on cheating: determinants of the "congruence effect"

Thirty-two male and 32 female introductory psychology students were given the opportunity to falsely report success (i.e., to cheat) on a series of objectively unsolvable achievement tasks. Consistent with previous evidence, a Personality X Situational Locus of Control interaction effect, accounting for 24% of the variance, was found whereby persons classified as having generalized internal locus of control beliefs (internals) cheated more when the task was described as requiring skill while those with external control beliefs (externals) cheated more when chance presumably determined performance outcomes. Differing rates of task persistence, postperformance belief and affect ratings. and stated reasons for cheating (or not) were consistent with both affective and cognitive theories in explaining the cheating to conform to their status on the internal stable dimension of ability, externals were concerned with maintaining a belief in their status as fortunate individuals, also conceived as an internal stable attributional determinant. No sex differences in cheating or persistence behavior were found.     

The effects of perceptual pretraining on concept identification and preference

The effects of perceptual pretraining on preferences and concept identification performance in five- and eight-year-old Ss were investigated. The results indicated that perceptual pretraining facilitated performance on a concept identification task with a non-preferred relevant cue for the five-year-olds, but not for the eight-year-olds. However, perceptual pretraining did not affect preference in either age group and Ss were as consistent in their preference responding before and after perceptual pretraining as was a control group that had not received perceptual pretraining. Preferences were highly consistent in both age groups over a one week period. Perceptual pretraining was interpreted to increase the usability of the less preferred dimensions for the younger Ss, and to leave the affective preference response unaltered in both groups.     

Comparatives,logical structures,and encoding in a transitive inference task

Four- to five-year-old children were asked questions on length involving single or double comparatives in a transitive inference task. The number of comparatives varied within or across pairs. The pairs of sticks were colorcoded. Initial pair-wise discrimination training on four adjacent pairs from a five-stick array with only verbal feedback was followed by tests, without feedback, on all possible pairs. When both comparatives were used, Ss learned adjacent pairs faster and more often reached criterion than when only one comparative term was used in training. In testing, Ss were successful on transitive inference tests only when the double-comparative relation was used within pairs during training. Retraining with visual feedback increased the number of Ss solving the inference test only in this condition. The findings are discussed in terms of how children may use processes other than logical operations to make transitive inferences.     

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.     

Warm-up effects in the learning of discrete motor skills

Three experiments were conducted to determine the influence of warming-up activities on performance and on learning in two discrete motor tasks. During initial trials on the criterion task, Ss were given various types of warming-up activities having an activity-set that was either the same as or different from the criterion task. Test trials followed in which all groups practiced the criterion task only. No significant differences in performance on the criterion task were found regardless of the appropriateness of the warming-up activity during initial trials. The results suggested that warming-up properties are not a factor in original learning of discrete motor skills.     

Evaluation apprehension and response withholding in solution of anagrams

Sixty male Ss who were classified as high or low scorers on the Sarason Test Anxiety Scale performed a difficult anagrams task either alone, before a passively observing experimenter or in the presence of an experimenter who both observed and evaluated the S's performance. Ss who were high in test anxiety attempted fewer anagrams and had fewer correct solutions in the Evaluated condition than in the Alone condition, but also had a higher proportion of correct solutions out of total attempts. Low test-anxiety Ss did not show variable performance across conditions for any measure. Follow-up studies showed that when Ss were encouraged to attempt partial solutions neither test anxiety nor experimental treatment influenced any of the measures of performance. State anxiety change scores from baseline to post-treatment assessment showed a generally negative correlation between anxiety and number of anagrams attempted. The results indicate that fear of failure engendered by test anxiety and experimenter evaluation caused Ss to withhold responding.
