ObjectivesExertion of self-control has been associated with impaired performance on subsequent physical tasks also requiring self-control, but it remains unknown why this occurs. This study, therefore, explored whether a) prior self-control exertion reduces subsequent persistence on a physically demanding task, and b) whether any observed performance decrements could be explained by changes in perceptions of pain.MethodIn a within-subject design, sixty-three individuals completed an easy (congruent) Stroop task or a difficult (incongruent) Stroop task that required self-control. Participants were then required to remain in a physically demanding posture (i.e., a ‘wall-sit’) until voluntary exhaustion and their perception of pain was recorded during the task.ResultsWhen participants completed the difficult Stroop task, they quit the wall-sit sooner. This decrement in performance was explained by greater perceptions of pain at the beginning of the wall-sit.ConclusionsPerceptions of pain may, therefore, be an important attentional mechanism explaining why self-control use interferes with subsequent persistence during physically effortful tasks.  相似文献

IntroductionAlzheimer's disease may modify moral judgment.ObjectiveIn two studies, we assessed the impact of dementia on blame and forgiveness. Study 1 compared the ways in which young adults, older adults, and older adults with dementia cognitively integrated two factors. Study 2 assessed the number of different factors that older adults with dementia were able to integrate during these moral judgments.MethodThe participants recorded their moral judgements in a blame task and in a forgiveness task. In study 1, the two questionnaires contained scenarios built from the combination of two factors. In study 2, the participants were confronted with the same tasks under three different conditions with scenarios that combined three, four or five factors.ResultsThe data from study 1 showed that the older adults with dementia did not combine the two factors in the same way as young adults did: the combination depended on the type of moral judgment. Study 2 revealed differences in moral judgment between older adults with dementia and adults without dementia in all tasks (i.e. with three, four or five factors combined).ConclusionDementia has an impact on moral judgments. Moral judgment among people with dementia is both task- and condition-dependant.  相似文献

Summary

In order to test various explanations of the fact that perceived competence appears to correlate positively with altruism, Ss were given false feedback as to their competence on a “visual creativity” test and then asked to help with a second task, writing creative color names. Three groups of Ss who were told they were competent were given reduced cost, increased happiness, and increased responsibility as reasons for helping; the other three groups were given no explanations, but were told that their competence was high, or low, or given no information. The three explanation groups helped more than the other three groups, and the reduced cost group helped more than the other five. The three dependent measures of helping (percentage of helpful Ss, duration of help, and magnitude of help) proved differentially sensitive to treatment and sex differences. Only the latter two measures showed greater helping in the reduced cost group; only the magnitude measure showed significantly greater helping for males than females.  相似文献

ObjectivesTo study the influence of fathers' and mothers' physical activity involvement and perceptions of their children's physical competence upon children's perceptions of competence and children's time spent in physical activity. Two forms of parental socialization influence were assessed: the direct influence of parents' actual physical activity (PA) behaviour (role modelling) on children's physical activity and the indirect influence of parents' beliefs systems about their children's PA competence on children's physical activity through children's self perceptions.MethodsLongitudinal, with data from 152 French children (M=9.5 yrs, SD=0.8 yrs) and their parents collected at two times over a 12-month period and examined through structural equation modelling (SEM).ResultsSEM indicated that mothers' role modelling behaviour had a direct effect on children's time spent in PA and that mothers' beliefs about their child's competence had an indirect effect on children's PA by influencing children's perceived competence which, in turn, contributed to children's level of physical activity involvement. Fathers' beliefs directly influenced their child's PA as did the children's own self-perceptions of competence.ConclusionsParents can affect their children's PA involvement in direct and indirect manners through their role modelling of physical activity and through their beliefs about their child's competence. Furthermore, the influence of fathers and mothers may be manifested in different ways. Father and mother could influence their child's PA by different processes.  相似文献

ABSTRACT

Recent research has shown that from early in development, children selectively form new beliefs in response to information supplied by others. However, little is known about the development of selective revision of existing beliefs in response to socially conveyed information. Such selective social belief revision has been extensively studied by social psychologists in the context of advice-taking. Here, we adapted the methods of this research tradition for studying selective advice-taking in young children and adults. Participants solved a perceptual judgment task, received advice, and subsequently made final decisions. The informational access (perceptual quality) of participants and advisor were experimentally manipulated. Adults revised their judgments systematically as a function of both their own and the advisor’s informational access whereas children based their adjustments only on their own informational access. Two follow-up experiments suggest, however, that this pattern of results in children reflected performance rather than competence limitations: In suitably modified tasks, children did proficiently consider both their own informational situation and that of the advisor in their selective social belief revision.  相似文献

Many studies of explanation have focused on higher level tasks and on how explanations draw upon relevant prior knowledge, which then helps in understanding some event or observation. However, explanations may also affect performance in simple tasks even when they include no task-relevant information. In three experiments, we show that explanations adding no task-relevant information alter performance in a sequential binary decision task. Whereas people with no explanation for why two events occurred at different rates tended to predict each outcome in proportion to their probability of occurrence (to "probability match"), people with an explanation tended to predict the more likely event more often (to "overmatch," a better strategy). These results suggest a broader view of explanation, which includes a role in shaping simple tasks outside of higher level reasoning.  相似文献

ObjectiveParticipation in organized youth sports has been shown to positively correlate with increased levels of exercise in adulthood. However, there is limited research to suggest why youth sports participation is related to increased physical activity as an adult. One possible explanation is that positive youth sport experiences lead youth to be more positively inclined to engage in physical activity as adults. Research into the positive youth development aspect of organized sports provides the framework for the current investigation.MethodsAdult participants (N = 234, Mage = 35.35) were asked to retrospectively assess their youth sports experiences using the “Four C's” (i.e., competence, confidence, connectedness, character) framework of positive youth development in sport. These assessments were then compared to current physical activity levels and related variables found in the Health Action Process Approach model (HAPA; Schwarzer, 2008).ResultsBivariate correlations revealed statistically significant and moderate correlations among competence, confidence, and connectedness and all of the HAPA variables including physical activity levels. Further, a MANCOVA analysis revealed that when participants were sub-divided into “non-intenders,” “intenders,” and “actors” using a validated staging algorithm, a general linear trend emerged for competence, confidence, and connectedness such that “non-intenders” rated these constructs the lowest and “actors” rated them the highest.ConclusionThese findings provide preliminary evidence that the relationship between participation in organized youth sports and adulthood levels of exercise could be contingent on how positively that experience is perceived.  相似文献

IntroductionInterruptions are mostly related to negative outcomes and researchers already found that the complexity or the length of interruptions modulate their deleterious effect on performance. However, none of them investigated the effect of the pleasantness of interruptions.ObjectiveThe objective of the study is to evaluate the impact of the pleasantness on both the correct completion of the interrupting task and the time required to resume the primary task.MethodWe designed a realistic email searching primary task during which 46 participants were either not interrupted or interrupted by a simple math addition task during which a positive or a negative picture was progressively revealed. We then asked participants how pleasant they found the interrupting task and investigated the effects of perceived pleasantness both on the interrupting task and on resuming the primary task.ResultsResults showed that performance on the interrupting task was worst and the time to resume the primary task was longer when participants found the task very pleasant or very unpleasant. Performance in both tasks was the best when participants gave intermediate pleasantness judgments. The findings were independent of the valence and arousal of the pictures used to manipulate task pleasantness.ConclusionThese results are discussed in light of empirical studies assessing the deleterious effects of emotions on cognition, and practical implications are proposed.  相似文献

Abstract

This paper reviews empirical research on adult age differences in the use of attention during visual search and classification tasks. This research suggests that the selective aspect of attention, in the sense of the ability to discriminate relevant and irrelevant information, is relatively resistant to age-related change. The capacity aspect of attention, in the sense of the limited processing resources that underlie task performance, appears to undergo age-related decline. Questions remain, however, regarding whether capacity-reduction explanations of age differences in cognitive performance have any advantages over explanations based on task complexity. Recent analyses of ageing and attention emphasise the potential contribution of formal models of cognitive performance.  相似文献

IntroductionWhile motivation has, for decades, been investigated as a key component of academic learning and performance, academic emotions have often been left out of the scope of investigation. According to several researchers, mathematics learning seems to be particularly affected by students’ emotions.ObjectiveThis paper is aimed at characterizing the emotions and motivation of eighth grade students in a mathematical setting and highlighting the cluster of emotions–activity emotions vs outcome emotions–which best predict math value, math self-concept, behavioral engagement and math performance.MethodData were collected through questionnaires from 115 students and analyzed through means comparisons and linear regressions.ResultsResults indicated that eighth grade students give a relatively high value to mathematics have a positive mathematics self-concept and are moderately engaged in mathematical tasks. Regression analysis showed that mathematics value and behavioral engagement are better explained by activity emotions while mathematics self-concept and performance are better predicted by outcome emotions.ConclusionThe implications of these findings in terms of educational practices are discussed at the end of this study.  相似文献

Past research has shown that ethnic minority students and females tend to participate less in collaborative groups because of their perceived lower status. This study examined the mediating effects that the task type (single-answer versus variable-answer) has on the relationship between diffuse status characteristics of participants (race – Black and White, and gender) and group members' interpersonal perceptions and participation within collaborative groups. Eight groups of four middle school students (Black female, Black male, White female, and White male) completed two tasks (variable-answer and single-answer) while being videotaped. The study found main effects of race and gender for participation and perceptions as well as task by gender effects for giving explanations and perceived quality of ideas. This article presents these findings in terms of gender-specific task characteristics and discusses implications of these results for educators and future research.  相似文献

Abstract

Reading competence is one of the main gateways to learning and serves as the foundation for nearly all academic subjects, but reading is not a natural skill. For beginning and struggling readers, the process of learning to read is often fraught with frustration. Thus, abilities to manage affect or emotions and maintain attention or focus (i.e. emotional self-regulation processes) are critical for literacy development and reading competence. Building on bio-social-ecological systems and contextual-developmental frameworks, we present a model of reading competence to integrate multidisciplinary empirical research on the fit between children’s emotional self-regulation processes and their literacy contexts and how these person-in-context dynamics influence reading competence through reading motivation and engagement. We present empirical research in support of the pathways in this model of reading competence, and call for increased multidisciplinary research that takes into consideration children’s literacy contexts and their neurobiological and behavioral assets as well as vulnerabilities in order to better understand the dynamical cognitive-emotional-motivational processes that underlie the development of reading competence from early childhood through young adulthood, including the timing and mechanisms of change to target for reading interventions to have optimal impact.  相似文献

ObjectivesBased on the Achievement Goal perspective [Dweck, C. S., Leggett, E. L. (1988). A social-cognitive approach to motivation and personality. Psychological Review, 95, 256–273; Nicholls, J. G. (1984). Achievement motivation: conceptions of ability, subjective experience, task choice, and performance. Psychological Review, 91, 328–346] and on Pekrun et al.'s [(2004). Beyond test anxiety: development and validation of the test emotions questionnaire (TEQ). Anxiety, Stress, and Coping, 17, 287–316] model of discrete class-related emotions, this study investigated the relation of achievement goals to discrete emotions in the Physical Education (PE) class.DesignCross-sectional.MethodParticipants were 319 Greek upper elementary school students who responded to a set of questionnaires assessing their achievement goal orientation, perceived competence, and the class-related emotions they experienced in the PE classes.ResultsHierarchical regression analyses showed that, after controlling for perceived competence and gender differences, task goals were positively related to positive activating emotions and negatively related to negative emotions. Ego goals exhibited a mixed picture as they were positively associated with pride and all the negative emotions. Furthermore, the relations between ego goals and emotions were qualified by an ego by task goal and by an ego by perceived competence interaction suggesting that ego goals were especially linked to emotional maladjustment when task goals were low and when competence perceptions were high rather than low.ConclusionUnique associations between task and ego goals and specific emotions were found, rendering insightful the disentanglement of positive and negative emotions into its components. The pursuit of task goals might help to counteract the emotional burden associated with ego goal pursuit whereas feeling competent to outperform when one endorses ego goals might perhaps put extra pressure on the pupils and, hence, have negative implications for their emotional adjustment.  相似文献

This paper presents some outcomes of research on the narrative construction of religion and sexual abuse in male victims. Twelve open biographic interviews with adult male survivors of childhood sexual abuse have been analysed for content and structure. Three narrative themes were identified to appear in all interviews: distance/proximity, power/powerlessness and guilt/innocence. Using statistical methods (correlations and cluster analysis), the relation was investigated between these narrative themes and categories of evaluation, life period addressed, religion, sexuality and significant others. At group level, very few correlations or patterns were found. Two possible explanations are discussed: (1) the lack of canonical stories and (2) the limitations to narrative competence as a result of traumatization. Structure analysis at the individual level yields relatively coherent patterns, so that the second explanation hypothesized seems less likely. Based on content and structure analysis, three narrative methods of construction are discussed: contrasting stories of sexual abuse and religion, sequencing stories and reinterpreting themes from both religion and sexual abuse. Finally, implications are discussed concerning researching canonical stories and their impact on coping, understanding and facilitating the creative potential of narrators, and the complicated relationship of individual constructions, confessional convictions and academic theological theories.  相似文献

IntroductionAlthough obesity stigma is pervasive, relatively little research has examined the extent to which the discrimination obese individuals experience extends to helping behavior.ObjectivesThe purpose of the current set of experiments was to determine whether strangers help heavy individuals less than non-heavy individuals, and to examine the impact that moderating cues (e.g., justifying or suppressing prejudice, Crandall & Eshleman, 2003) of weight-based discrimination and gender might have on helping behavior.Study 1The first study was an experiment conducted online through MTurk. Participants rated their willingness to support a proposed charity event and their perceptions of the event organizer, whose picture was manipulated to be heavy or non-heavy. We found evidence that people were less willing to help and held more negative perceptions of heavy (than non-heavy) individuals.Study 2The second study was a field experiment in which confederates either wearing or not wearing obesity prosthetics solicited help from others on a college campus. Relative to the non-heavy, heavy individuals again were less likely to be helped and received more impolite interpersonal treatment, as rated by observers. Additionally, women were denigrated more than men for being heavy, but cues that suppressed discrimination helped increase the amount of help received and the politeness of strangers.ConclusionThe overt and subtle discrimination overweight individuals experience extends to situations when they are asking for help, and this is especially the case for heavy women. However, displaying stereotype-inconsistent cues benefit overweight individuals by increasing the likelihood of them being helped and treated well.  相似文献

ObjectivesMotivated by a paucity of research on sports forecasting, this paper examines how well individuals with varying degrees of relevant knowledge predict football (soccer) and how much confidence they have in their predictions.Design and procedureThree groups of participants (110 art students, 81 sports students, and 85 bettors) representing three levels of knowledge (poor, moderate, and expert) performed five forecasting tasks with relation to the outcome of the first round of the World Cup 2006. The tasks were assumed to reflect different degrees of complexity. About half of the participants obtained relevant information (world rankings). The participants stated their confidence in connection to conducting those tasks.ResultsWhereas the groups had roughly similar levels of performance in three tasks (i.e., predicting the teams qualifying for the second round as well as two types of match statistics), the knowledgeable and expert participants were better at predicting scores and percentage of ball possession in the matches than the naïve participants. Relatively few participants performed better than the simple rule that followed world rankings. Regardless of task complexity, the knowledgeable and expert participants were found to be significantly more confident about their forecasts than the naïve participants. Access to information had limited influence on forecasting performance and confidence.ConclusionThe present study shows that the forecasting performance of football experts and laypeople varies dependent on task. For easy tasks, they tend to predict equally well, partly because laypeople might use well-adapted heuristics. Once the prediction tasks become more difficult, the experts may take advantage of their domain-specific skills and produce forecasts that excel those of the laypeople.  相似文献

IntroductionAutomation research has identified the need to monitor operator attentional states in real time as a basis for determining the most appropriate type and level of automated assistance for operators doing complex tasks.ObjectiveThe development of a methodology that is able to detect on-line operator attentional state variations could represent a good starting point to solve this critical issue.ResultsWe present a short review of the literature on different indices of attentional state and discuss a series of experiments that demonstrates the validity and sensitivity of a specific eye movement index: saccadic peak velocity (PV). PV was able to detect variations in mental state while doing complex and ecological tasks, ranging from air traffic control simulated tasks to driving simulator sessions.ConclusionThis research could provide several guidelines for designing adaptive systems (able to allocate tasks between operators and machine in a dynamic way) and early fatigue-and-distraction warning systems to reduce accident risk.  相似文献

ObjectivesSocial goal orientations, which reflect ways of conceptualizing competence in terms of social relationships with others, have been researched minimally in the physical domain. While the relationship between task and ego orientations and motivational outcomes has been well-studied, the link of friendship, group acceptance, and coach praise orientations with enjoyment, perceived physical competence, and intrinsic motivation warrants further study.MethodMale and female middle-school students (N = 303) completed questionnaires assessing task, ego, coach praise, friendship, and group acceptance orientations; enjoyment; perceived physical competence; and motivation. Two approaches to data analysis (variable-centered, person-centered) examined whether social orientations were significantly related to motivational outcomes among adolescents.ResultsVariable-centered analysis (i.e., canonical correlation) showed that social orientations were related to enjoyment, perceived physical competence, and intrinsic motivation. Person-centered analyses (i.e., cluster analysis, MANOVA) classified participants with similar patterns of goal orientations and then compared the emergent groups on motivational outcomes. Participants who defined success using either higher task, ego, and social goal orientations or higher friendship and lower ego orientations reported the most adaptive responses (higher perceived competence, enjoyment, and intrinsic motivation).ConclusionsSocial orientations in sport are important to consider alongside task and ego orientations in research stemming from achievement goal theory. Defining success or competence in terms of social relationships can have positive motivational benefits in sport.  相似文献

ObjectivesThis study examined the effects of mental fatigue on people's decisions to engage in an acute bout of exercise quantitatively, through a sequentially mediated pathway consisting of perceived effort and benefit vs. cost valuations and qualitatively, using exit interviews to survey the conscious reasoning behind participants' choices.DesignMixed methods, randomized, experimenter blind to group.MethodParticipants (N = 84, Mage = 19.07 ± 1.86 years) completed either a high cognitive demand (incongruent Stroop) task or low cognitive demand (documentary viewing) task for 12 min. Before and after the cognitive task, participants rated their anticipated effort and subjective evaluations (benefits and costs) of engaging in a 20-min moderate-to-vigorous intensity exercise task. After completing the latter ratings, participants chose between the exercise task or a non-exercise task (seated “free time” and use of smartphone or computer). Participants were led to believe they would actually engage in the task; however, once their choice was made, they were not required to complete the task but were invited to complete a semi-structured interview to probe the reasoning behind their choice.ResultsSerial mediation analyses revealed a significant indirect effect from mental fatigue to choice through perceived effort and benefit vs. cost valuations (95% C.I. = −0.01 to −0.0004). Qualitative data, organized by categories based on group/choice pairings, yielded twelve unique codes explaining how the cognitive tasks affected choice.ConclusionsResults demonstrate mental fatigue alters decision-making through a sequentially mediated process including subjective perceptions of effort, benefits, and costs. Interview responses also highlight the individual-level consequences of completing cognitively demanding and non-demanding tasks on effort-based decision-making. Future research should explore additional feeling states as they relate to people's choices to engage in exercise or sedentary behaviors.  相似文献
