An Examination of Metacognitive Strategy Use and Monitoring Skills by Competitive Middle Distance Runners

This study investigated metacognitive strategy use by competitive athletes. Specifically, it tested the extent to which competitive middle-distance runners rely upon internally-focused metacognitive strategies versus externally-focused thoughts when they compete. In addition, the link between strategic knowledge and the regulation of such strategies during a novel self-paced task was investigated. Division I collegiate runners from the Midwestern U.S. (M age = 19.6, SD = 1.23) provided written responses to inventories about strategy use and completed a performance task requiring them to monitor and adjust their running pace. Results indicated an overwhelming tendency for the competitive runners in this study to report internally-focused strategies as opposed to externally-focused thoughts. The bulk of the thoughts that runners reported focused on either (a) monitoring bodily processes and form or (b) information management strategies that related to race tactics during competition. Furthermore, evidence was found for a link between self-report strategic knowledge and the ability to regulate one's performance on the self-paced task.     

The effects of transcranial direct current stimulation (tDCS) on multitasking performance and oculometrics

Multitasking is the ability to perform more than one task simultaneously. The need to multitask is common in many industries especially within the military with tasks such as air traffic controllers, cyber defense operators and image analysts. However, as the time on task increases, information throughput can become overwhelming resulting in a performance decrement. Through task prioritizing, the operator is able to maintain performance on specific subtasks in which they selected as high importance while other subtasks experience a decrement. The objective of this study was to evaluate the effects of transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (ldLPFC) on information processing capabilities to improve individual and overall multitasking performance while performing the multi-attribute task battery (MATB). Two groups of 8 participants each received either 2 mA of anodal or sham tDCS while performing MATB. In addition, eye tracking was implemented to record eye movement patterns. In doing so, we were able to determine how much time the operator allocated to each of the subtasks within MATB and how their task priorities changed as workload demands increased. The findings provided evidence that 2 mA of anodal tDCS during MATB significantly improved overall information throughput compared to the sham group. With respect to the individual subtasks, communication and system monitoring displayed the greatest enhancement with anodal tDCS. Our data suggests that tDCS could be a useful tool to enhance information processing capabilities during a multitasking paradigm resulting in improved processing capabilities and information throughput.     

Assessment and selection of paired associate strategies: A developmental study

First, third, and fifth graders who had been instructed to use an interaction strategy and a repetition strategy on two separate paired associate tasks were asked on which task they had remembered better and why. Subjects were then given another paired associate task and told they could use any way they wanted to remember. Memory performance was better when the interaction strategy was used than when the repetition strategy was used. A significant majority of third and fifth graders correctly judged which task they had performed better on, and the number of subjects doing so increased with grade. Only among fifth graders, did the majority of subjects explain their judgments by referring to the use of the interaction strategy. Use of the interaction strategy on Task 3 did not increase with grade but was shown by a significant majority of first and fifth graders. Use of the interaction strategy on Task 3 was more frequent among subjects who referred to the use of the interaction strategy in explaining their choice of their more successful task than among those who did not.     

Prevalence of interactions and influence of performance constraints on kick outcomes across Australian Football tiers: Implications for representative practice designs

Representative learning design is a key feature of the theory of ecological dynamics, conceptualising how task constraints can be manipulated in training designs to help athletes self-regulate during their interactions with information-rich performance environments. Implementation of analytical methodologies can support representative designs of practice environments by practitioners recording how interacting constraints influence events, that emerge under performance conditions. To determine key task constraints on kicking skill performance, the extent to which interactions of constraints differ in prevalence and influence on kicking skills was investigated across competition tiers in Australian Football (AF).A data sample of kicks (n = 29,153) was collected during junior, state-level and national league matches. Key task constraints were recorded for each kick, with performance outcome recorded as effective or ineffective. Rules were based on frequency and strength of associations between constraints and kick outcomes, generated using the Apriori algorithm.Univariate analysis revealed that low kicking effectiveness was associated with physical pressure (37%), whereas high efficiency emerged when kicking to an open target (70%). Between-competition comparisons showed differences in constraint interactions through seven unique rules and differences in confidence levels in shared rules.Results showed how understanding of key constraints interactions, and prevalence during competitive performance, can be used to inform representative learning designs in athlete training programmes. Findings can be used to specify how the competitive performance environment differs between competition tiers, supporting the specification of information in training designs, representative of different performance levels.     

Between-task competition for intentions and actions

People can switch quickly and flexibly from one task to another, but suffer the effects of between-task competition when they do so: After switching, they tend to be distracted by irrelevant stimulus information and hampered by incorrect actions associated with recently performed tasks. This competition results in performance costs of switching, as well as a bias against switching when there is choice over which task to perform, particularly when switching from a difficult task to an easier one. Two experiments investigated the locus of these between-task competition effects in voluntary task switching. Participants switched between an easy location classification and a harder shape classification, making two responses on each trial: the first to register their task choice, the second to perform the chosen task on a subsequently presented stimulus. The results indicated that participants chose to perform the difficult shape task more often than the easier location task, evidence that between-task competition affects intentions that are expressed independently of task-specific actions. The bias was stronger in participants with faster choice speed, suggesting that these influences are relatively automatic. Moreover, even though participants had unlimited time to choose and prepare a task before stimulus presentation, their subsequent performance was nonetheless sensitive to persisting effects of between-task competition. Altogether these results indicate the pervasive influence of between-task competition, which affects both the expression of global task intentions and the production of task-specific actions.     

Depression and Judgment of Control: Impact of a Contingency on Accuracy

In this study we sought to determine whether mild depressives and nondepressives could respond adaptively and self-correct their judgments of contingency when it was clearly advantageous to do so. Ninety-six undergraduates were given four contingency-learning tasks involving pressing or not pressing a key to turn on a light and to judge the degree of control their responses had over light onset. On the first task, which included a monetary contingency only on light onset, mild depressives were relatively accurate in their judgments of control. Tasks 2 through 4, which also included a monetary contingency and feedback on accuracy of judgment of control, showed a Mood x Task interaction. Mild depressives, but not nondepressives, became more accurate, and by the last task, mild depressives were more accurate than nondepressives. Results were discussed in terms of incentive, feedback, and task exposure.     

The Effect on Behavior of Being in a Control Group

This study examined how individuals react when they know they are missing an experimental treatment as a function of having been assigned to a control group. Subjects in one condition were informed that they were a control group and would miss receiving extra money for doing well on experimental tasks. Subjects in a second condition were informed that they would miss receiving electric shocks for doing poorly on the same tasks. In the third condition subjects were given no information about missed conditions. Subjects who believed they were missing the chance to receive extra money tended to do worse, while those who believed they were missing the shocks did better on the experimental tasks than did subjects unaware of any other condition. In addition, missing-reward subjects made more errors and did less work than did missing-punishment subjects. There were no differences in attitude towards the experiment as a function of experimental condition. Differences in task performance were discussed in terms of inequity theory (Adams, 1963), the evaluation of social programs, and Campbell's (Note 1) suggestion of "informed randomization.     

Intensity and direction dimensions of competitive state anxiety: a time-to-event approach

The purpose of the present study was to examine the temporally patterned changes in intensity and direction of competitive state anxiety prior to and during competition as well as correlations among intensity and direction on the Competitive State Anxiety Inventory-2D subscale scores. 99 athletes completed the inventory one day before and an hour before the competition, based on how they felt during that time, and 30 min. after the competition with reference to how they felt during the competition. Analysis indicated different temporal patterning in subscale scores prior to competition. Correlations were medium (.40) for Intensity and Direction dimensions. Significant differences were noted between scores of those classified as Facilitators and Debilitators on the Intensity dimension. The results support the multidimensional nature of competitive anxiety. Moreover, additional information lies in directional interpretation of competitive anxiety and self-confidence.     

Effects of competition on video-task performance in monkeys (Macaca mulatta)

The effects of competition on performance of a video-formatted task were examined in a series of experiments. Two rhesus monkeys (Macaca mulatta) were trained to manipulate a joystick to shoot at moving targets on a computer screen. The task was made competitive by requiring both animals to shoot at the same target and by rewarding only the animal that hit the target first each trial. The competitive task produced a significant and robust speed-accuracy trade-off in performance. The monkeys hit the target in significantly less time on contested than on uncontested trials. However, they required significantly more shots to hit the target on contested trials in relation to uncontested trials. This effect was unchanged when various schedules of reinforcement were introduced in the uncontested trials. This supports the influence of competition qua competition on performance, a point further bolstered by other findings of of behavioral contrast presented here.

Effects of team outcome on children's self-perception: Little League baseball

Abstract.— To determine how children use various attributional categories in making judgments about themselves as a function of team performance outcomes, answers were sought to the questions of how invariant children's perceptions of their characteristics are, and how they expect social agents to judge them under the various outcome conditions of team performance. Subjects were 300 Little League baseball players. Team failure did not decrease the players' judgments of their own internal qualities (ability and effort) but did decrease their judgments of those of the team. In addition, the players judged themselves and expected social agents (coach and spectators) to judge them as being unlucky and having a difficult task following team failure. Theoretical implications of the results were discussed.     

The effects of position in a display upon problem solving

Sixty-four subjects, aged between 15 and 72 years were told how to carry out a problem-solving task, whose difficulty could be varied by changing the position of an index card in relation to a display and control.

The outstanding feature, particularly of the older group's performance was the repetition of the same two kinds of mistake. Their failure seemed mainly due to an inability to rid themselves of their wrong “solutions,” in spite of the constant information indicating the mistake at each position. Whilst these differences between the age groups were hot pronounced at the easiest task, they were at the most difficult.

It is suggested that: Firstly, the procedure of giving a subject the solution to a problem and observing how he reconciles his information with it, though only operating in a circumscribed area of problem-solving, is a genuine example of thinking, and, particularly where certain kinds of mistake can be predicted, it enables the experimenter to gain a more exact impression of what a subject is doing. Secondly, the manipulation of spatial contiguities lends itself to flexible and fairly precise measurement, and the principle might usefully be extended to other variables such as size, time intervals, colour, etc.     

How distraction affects pedestrian response: Evidence from behavior patterns and cortex oxyhemoglobin changes

ObjectivesDistracted walking is a major cause of pedestrian road traffic injuries, but little is known about how distraction affects pedestrian safety. The study was designed to explore how visual and auditory distraction might influence pedestrian safety.MethodsThree experiments were conducted to explore causal mechanisms from two theoretical perspectives, increased cognitive load from the distraction task and resource competition in the same sensory modality. Pedestrians’ behavior patterns and cortex oxyhemoglobin changes were recorded while they performed a series of dual tasks.ResultsFour primary results emerged: (a) participants responded more slowly to both visual and auditory stimuli in traffic, as well as walked more slowly, while talking on the phone or text messaging compared to when undistracted or listening to music; (b) when participants completed pedestrian response tasks while distracted with a high cognitive load, their response was significantly slower and poorer than when they carried out a lower cognitive load distraction task, (c) participants had higher levels of oxy-Hb change in cortices related to visual processing and executive function while distracted with a higher cognitive load; and (d) participants' responses to traffic lights were slower and resulted in a higher activation in prefrontal cortex and occipital areas when distracted by a visual distraction task compared to when distracted with an auditory task; similarly, brain activation increased significantly in temporal areas when participants responded to an auditory car horn task compared to when they responded to visual traffic lights.ConclusionsBoth distracting cognitive load demands and the type of distraction task significantly affect young adult pedestrian performance and threaten pedestrian safety. Pedestrian injury prevention efforts should consider the effects of the type of distracting task and its cognitive demands on pedestrian safety.     

Competition-cooperation as a mediator of locus of control and achievement

To test the hypothesis that internals will achieve more than externals in situations where competition is preeminent but not where cooperation is required, 300 children completed a digit-symbol task and a locus of control scale. Children were divided into internals and externals, placed in situations varying in competition and cooperation, and readministered the digit-symbol task. While the general hypothesis was supported, it was found that externals increased from their significantly low performance in the competitive situation to equal performance with internals in the cooperative situation. These findings are discussed in terms of their meaning for social learning theory and their relevance for the potential development of classroom teaching methods for increasing achievement behavior.     

The effects of competition on achievement motivation in Chinese classrooms

Background: Laboratory studies have consistently found that competition induces performance goals and affects learning motivation. However, the ecological validity of these results is yet to be established. There is a need for investigation of whether the results hold in both the classroom context and non‐Western culture. Aim: The study investigated the effects of competition on learning motivation among Chinese students in an authentic classroom setting. Sample: The participants were 52 students of grade 7 from two Hong Kong secondary schools. Method: They were randomly assigned to either competitive or non‐competitive conditions in a 2‐hour Chinese typewriting course. Results: Students in the competitive condition performed better in easy tasks than their counterparts in the non‐competitive condition. However, they were more performance‐oriented and more likely to sacrifice learning opportunities for better performance. They were also prone to have worse self‐evaluation after failure. Although there were no statistically significant differences between the two conditions in task enjoyment and achievement attribution, the direction of the differences was consistently unfavourable to students in the competitive condition. Conclusion: The findings were consistent with the predictions of goal theory. Competitiveness induces performance goals and worse self‐evaluation after failure among Chinese students in a classroom setting, as was found with Western students in a laboratory setting.

The perception of control in loud noise

Perception of control is known to affect performance under stress. Two experiments are reported the object of which was to find out how loud noise during a contingency assessment task influences perceived control. Subjects were required to choose one of two responses, note one of two results, and then provide an overall percentage estimation of the degree of contingency present after 40 trials. Subjects made these judgments for one of three levels of objective contingency (25%, 50%, 75%), either in quiet (55 dBA) or in loud noise (95 dBA) conditions. The first experiment involved a series of randomly chosen, preprogrammed outcomes for noncontingent trials. An unexpected effect of noise was that subjects improved their successes in predicting events, and could only have done so by finding sequential structure in the preprogrammed alternations. They also overestimated control relative to contingency data actually received, at the 25% objective contingency level, but the result could have been dependent on different base levels of data actually received. A second experiment, with a random generation of outcomes for noncontingent trials, resulted in no differences in success levels, but confirmed that noise is associated with the overestimation of contingency at the 25% objective contingency level and demonstrated the same effect for the 50% level. The results are discussed in the context of the 'illusion of control'.     

Run-up strategies in competitive long jumping: How an ecological dynamics rationale can support coaches to design individualised practice tasks

Understanding how individuals navigate challenging accuracy demands required to register a legal jump is important in furthering knowledge of competitive long jumping. Identification of co-ordination tendencies unique to each individual emphasises the need to examine the presence of unique movement solutions and presents important information for individualisation of training environments. In this study, key measures of gait were recorded during the long jump run-ups of 8 athletes at 8 national level competitions in the 2015 and 2016 Australian track and field seasons. These gait measures were examined to identify whether different visual regulation strategies emerged for legal and foul jumps for each competitor. Emergence of different footfall variability data curves, illustrating how step adjustments were distributed across the run-up for each athlete, suggests that athletes interacted differently with features of the competition environment. This observation highlights the importance of movement adaptability as constraints change and emerge across each performance trial. Results provided further support in conceptualising the run-up as a continuous interceptive action task consisting of a series of interconnected events (i.e., individual step lengths) influencing the regulation of gait towards the take-off board. This information can be used by coaches and practitioners in designing training environments that promote athlete adaptation of more functional movement solutions closely matched to the dynamics of competition environments. Results suggest that training designs that help athletes to search, explore and exploit key sources of information from the competition environment will enhance the fit between the individual and the environment and the development of rich, adaptable movement solutions for competitive performance.     

The role of age and prior beliefs in contingency judgment

This experiment investigated how prior beliefs affect young and older adults' ability to detect differences in objective contingency. Participants received new evidence that the objective contingency between two events was positive, negative, or zero when they believed that there was a positive or negative relationship between events, when they believed that the events were unrelated, and when they had no knowledge of the relationship between the events. They were then asked to estimate the objective contingency and recall the contingency evidence. Beliefs that events were or could be related improved young adults' contingency discrimination. Moreover, these beliefs did not produce biases in young adults' memory for the contingency evidence, but rather affected how they weighted this evidence at judgment. In contrast, these same beliefs did not improve older adults' contingency discrimination, but did produce biases in their memory for the evidence that were similar to those seen in their judgment. These findings are discussed in terms of age-related changes in working memory executive processes that impair older adults' ability to fully evaluate both belief-confirming and disconfirming contingency evidence and update their beliefs with this information.
