This study examined the relationship of preexisting efficacy for exercise with perceptions of effort expenditure and in-task affect during exercise testing. Subjects comprised sedentary, middle-aged adults participating in a submaxi-mal cycle ergometer-graded exercise test. Perceptions of efficacy were assessed prior to and following exercise testing while perceptions of effort expenditure and in-task affect were assessed at 70% of predicted maxim heart rate. Highly efficacious subjects had lower perceptions of effort expenditure and reported more positive affect during exercise than did their less efficacious counterparts. Affective responses during exercise were in turn significant predictors of posttest self-efficacy. These results are discussed in regard to the importance of examining the role of personal efficacy in the formation of exercise-related affect and affective responses as sources of efficacy or competence information in exercise.  相似文献

The authors hypothesized that similarity to the ideal self (IS) simultaneously generates attraction and repulsion. Attraction research has suggested that a person likes individuals who are similar to his or her IS. Social comparison research has suggested that upward social comparison threatens self-evaluation. In Experiment 1, attraction to a partner increased and then decreased as the partner became more similar to and then surpassed the participant's IS. In Experiment 2, the cognitive and affective components of attraction increased and decreased, respectively, as the partner approached and surpassed the participant's IS to the extent that the dimension of comparison was meaningful and participants andicipated meeting their partner. Similarity to the IS generates opposing cognitive and affective reactions when the self-evaluative threat of upward comparison intensifies.  相似文献

Writing processes have been studied extensively from the cognitive point of view, but little attention has been given to the affective aspects of this activity. In fact, writing experience seems to be relevant to a person not only because it is a complex cognitive activity, but also because it often has an affective characterization. The aim of the present study was to investigate writing as a meaningful activity, that is, to analyze the way in which pupils of different grade levels construe this activity. The study was divided into two phases: (a) interviews with pupils in order to select relevant elements (i.e., writing situations and contexts) and (b) subjects' elicitation of constructs and evaluation of elements. From the qualitative and quantitative analyses of the grids, a developmental trend emerged. Whereas the younger subjects frequently elicited constructs related to the affective dimension of writing, as age increased, the cognitive dimension became more evident.  相似文献

The present study investigates the comprehension of syntactic and affective prosody in adults with autism spectrum disorder without accompanying cognitive deficits (ASD w/o cognitive deficits) as well as age-, education- and gender-matched unimpaired adults, while processing orally presented sentences. Two experiments were conducted: (a) an on-line sentence completion task containing local subject/object ambiguities and (b) an affective prosody task exploring the comprehension of six emotions. The syntactic prosody task revealed that the experimental group performed similar to the control group on the fillers and the object condition. On the other hand, the ASD w/o cognitive deficits group manifested lower accuracy compared to the unimpaired controls in the subject reading condition, as well as slower reaction times in all conditions. In the affective prosody task, the experimental group performed significantly worse than the controls in the recognition of the emotion of surprise, whereas no differences between the experimental and the control group were attested in the recognition of all other emotions. A positive correlation was found between the two tasks in the ASD w/o cognitive deficits group. Thus, individuals with ASD w/o cognitive deficits face slight difficulties with the decoding of prosody, both the syntactic and the affective one. More specifically, these difficulties are attested in the most difficult conditions, i.e. the subject reading and the emotion of surprise.  相似文献

The authors posit that higher levels of guilt-proneness are associated with higher levels of affective organizational commitment. To explain this counterintuitive link, the authors suggest that a dispositional tendency to feel guilt motivates individuals to exert greater effort on their work-related tasks that, in turn, strengthens their affinity for the organization. The authors tested this idea using a laboratory study and field data from 2 samples of working adults. Individuals who are more guilt-prone reported higher levels of organizational attachment compared with less guilt-prone individuals. Furthermore, mediation analyses indicate that the link between guilt-proneness and affective commitment is driven by greater task effort. The authors discuss the implications of these findings for understanding the affective drivers of commitment in organizations.  相似文献

Competition strongly affects individual effort and performance for both individuals and groups. Especially in work settings, these effort gains might come at the cost of individual well‐being. The present study tested whether competition increases both effort (as indicated by task performance) and stress (in terms of cardiovascular reactivity and affective response), and whether this effect is further qualified by the type of competition (interindividual vs. intergroup), using a cognitive computer‐based task and a 2 (Group: Yes, No) × 2 (Competition: Yes, No) × 2 (Gender) factorial design (N= 147). All participants either worked as a representative of a group or as an individual, and were offered performance‐related incentives distributed in a lottery. In the competition conditions, participants were informed that they competed with someone else, and that only the winning person/team would take part in the lottery. Consistent with expectations, competition increased both individual effort and cardiovascular reactivity compared to non‐competitive work. Moreover, for female participants, intergroup competition triggered increased effort and more positive affect than interindividual competition. Aside from documenting costly side‐effects of competition in terms of stress, this study provides evidence for a stress‐related explanation of effort gains during intergroup competition as compared to interindividual competition.  相似文献

Previous studies suggest that individuals with Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, show specific weaknesses in visual attention and response inhibition within the visuospatial domain. Here we examine the extent to which impairments in attentional control extend to the visuomotor domain using a well‐validated measure of choice stepping reaction time (CSRT) in individuals with WS. We examined the interaction between executive control and visually guided stepping using a verbal fluency dual‐task or Go/NoGo paradigm during CSRT performance. Relationships between dual‐task and inhibitory stepping and behavioural inattention and hyperactivity were also examined. Our results showed clear dual‐task costs in stepping response times when performing a concurrent cognitive task in the WS group when compared to spatial and verbal ability matched typically developing controls. Although no group differences in stepping accuracy were observed between the WS and typically developing control groups, the WS group showed progressive slowing and more variable response times across the duration of the Go/NoGo task. These results suggest dysfunction in circuits involved in top‐down attentional control processes in WS. These findings provide novel evidence that core executive control deficits in WS extend to the visuomotor domain, and impact on ADHD‐related inattentive symptoms.  相似文献

Detecting behavioral errors is critical for optimizing performance. Here, we tested whether error monitoring is enhanced in emotional task contexts, and whether this enhancement depends on processing internal affective states. Event-related potentials were recorded in individuals with low and high levels of alexithymia—that is, individuals with difficulties identifying and describing their feelings. We administered a face word Stroop paradigm (Egner, Etkin, Gale, & Hirsch, 2008) in which the task was to classify emotional faces either with respect to their expression (happy or fearful; emotional task set) or with respect to their gender (female or male; neutral task set). The error-related negativity, a marker of rapid error monitoring, was enhanced in individuals with low alexithymia when they adopted the emotional task set. By contrast, individuals with high alexithymia did not show such an enhancement. Moreover, in the high-alexithymia group, the difference in the error-related negativities between the emotional and neutral task sets correlated negatively with difficulties identifying their own feelings, as measured by the Toronto Alexithymia Scale. These results show that error-monitoring activity is stronger in emotional task contexts and that this enhancement depends on processing internal affective states.  相似文献

It has been reported that engagement in several kinds of cognitive activity can successfully inhibit unpleasant emotions. In this study, we tried to replicate the previous finding that cognitive activity can modulate subsequent psychological and physiological emotional processes and to investigate whether prior cognitive activity can attenuate implicit emotional processes triggered by subliminal emotional stimuli. Sixty students were randomly divided into three groups (cognitive task group, noncognitive task group, control group). The cognitive task group was asked to engage in an n-back task, while the control group was asked to stay calm. The noncognitive task group was asked to do a handgrip-squeezing task. All participants then engaged in a version of a subliminal affective priming task where they were unconsciously exposed to affectively negative pictures. The cognitive task group showed lower negative experiences after the subliminal affective priming task and a substantial reduction in their heart rate responses, as compared with the other groups. These results provide evidence that engagement in cognitive activity can attenuate emotional processes in an automatic and unconscious manner.  相似文献

Subjective cognitive effort: a model of states, traits, and time   总被引:2,自引:0,他引:2  
Self-regulation theories were used to develop a dynamic model of the determinants of subjective cognitive effort. The authors assessed the roles of malleable states and stable individual differences. Subjective cognitive effort and perceived difficulty were measured while individuals performed an air traffic control task. As expected, Conscientiousness moderated the effort trajectory. Individuals with high Conscientiousness maintained subjective cognitive effort at high levels for longer than their counterparts. There were also individual differences in reactions to perceptions of task difficulty. The intra-individual relationship between perceived difficulty and subjective cognitive effort was stronger for individuals with low ability or low Conscientiousness than for their counterparts. A follow-up study showed that the measures of perceived difficulty and subjective cognitive effort were sensitive to a task difficulty manipulation as well as that the relationship between perceived difficulty and subjective cognitive effort held after controlling for self-set goal level. These findings contribute to the self-regulation literature by identifying factors that influence changes in subjective cognitive effort during skill acquisition.  相似文献

Previous research on feedback frequency suggests that more frequent feedback improves learning and task performance (Salmoni, Schmidt, & Walter, 1984). Drawing from resource allocation theory (Kanfer & Ackerman, 1989), we challenge the “more is better” assumption and propose that frequent feedback can overwhelm an individual’s cognitive resource capacity, thus reducing task effort and producing an inverted-U relationship with learning and performance over time. We then propose that positive and negative affective states will moderate the inverted-U relationship between feedback frequency and task performance. We test these propositions in an experimental study where the frequency of task feedback is manipulated. Results show that feedback frequency exhibits an inverted-U relationship with task performance, and this relationship is mediated by task effort. This curvilinear relationship is then moderated by individual’s positive affective state.  相似文献

There are wide individual differences in the characteristic intensity of affective response to the same emotion-evoking event. The processes whereby individuals come to experience strong or mild emotional responses when exposed to the same affect-provoking stimuli are still unclear. In these studies, we propose that individual differences in affect intensity are associated with certain cognitive operations used during exposure to emotion-relevant stimuli. Specifically, cognitive operations that involve personalizing, generalizing, and selective abstraction were hypothesized to discriminate subjects high and low in affect intensity. Two studies replicated support for the hypothesis that subjects high on the affect-intensity dimension engage in more personalizing/empathic and more generalizing/elaborative cognitive operations than do subjects low on the affect-intensity dimension. The same cognitive operations discriminated groups high and low in affect intensity in response to both positive and negative emotional stimuli. Also, the cognitions that discriminated subjects high and low in affect intensity occurred only in response to affective stimuli; neutral stimuli did not evoke divergent cognitive operations for these two groups. Finally, a high degree of consistency was found in the use of emotion-relevant cognitive operations across positive and negative affective stimuli.  相似文献

The role of affective responses to effort in the regulation of physical activity behavior is widely accepted. Yet, to investigate these affective responses during physical activity, most studies used direct self-reported measures that are prone to biases (e.g., social desirability, ability to introspect). To reduce these biases, we used an indirect measure (i.e., an affect misattribution procedure) that assessed the implicit affective valence elicited by physical effort in 42 healthy young adults. Specifically, participants rated the pleasantness of neutral human faces presented in a virtual environment while cycling at different intensities. We used this rating as an indicator of implicit affective valence. Results showed that higher perceived effort was associated with lower pleasantness ratings of neutral faces, with this effect only emerging at moderate-to-high levels of perceived effort. Further analyses showed that higher actual effort was also associated with lower pleasantness ratings of neutral faces. Overall, these findings suggest that higher levels of perceived effort are associated with decreased affective valence during physical activity. Finally, this study presents a new indirect measure of affective valence during physical activity.  相似文献

The aim of this research was to investigate the influence of a social-evaluative context on simple cognitive tasks. While another person present in the room evaluated photographs of beautiful women or landscapes by beauty/attractiveness, female participants had to perform a combination of digit-categorization and spatial-compatibility task. There, before every trial, one of the women or landscape pictures was presented. Results showed selective performance impairments: the numerical distance effects increased on trials that followed women pictures but only, if another person concurrently evaluated these women pictures. In a second experiment, using the affective priming paradigm, the authors show that female pictures have a more negative connotation when they are concurrently evaluated by another person (social-evaluative context) than when they are not evaluated (neutral context). Together, these results suggest that the social-evaluative context triggers mild negative affective reactions to women pictures which then impair performance in an unrelated task.  相似文献

This experiment sought to clarify the potential role of emotional feelings in the systematic impact of implicitly processed affective stimuli on mental effort mobilisation. Participants worked on an attention task during which they were primed with suboptimally presented happiness versus sadness expressions. Before the task, half the participants received a cue for the possible affective influence of “flickers” to be presented during the task. This manipulation usually reduces the impact of conscious feelings on resource mobilisation. As anticipated, sadness primes resulted in higher experienced task demand and higher mental effort (stronger cardiac contractility assessed as shortened pre-ejection period) than happiness primes. Most importantly, instead of reducing the prime effects on mental effort, the cue manipulation significantly increased participants’ effort in general, reflecting additional cognitive demand. The results speak against the idea that affect primes influence effort mobilisation by eliciting conscious emotional feelings.  相似文献

不断加剧的经济不平等问题对个体和社会有着巨大危害,然而人们对经济不平等却有着较高的容忍性。基于个体心理的研究证据,本文提出认知和动机双重路径模型来解释个体容忍和支持经济不平等问题。在认知路径上,个体倾向于低估当前社会的经济不平等程度和将经济不平等评价为公平的;在动机路径上,个体预期经济不平等将带来自我利益的增加。未来研究应进一步整合多重心理机制间的关系,并探索有效干预手段以增加人们对减少经济不平等的支持。  相似文献

The relationship between cognitive and sensory processes in the brain contributes to the regulation of affective responses (pleasure–displeasure). Exercise can be used to manipulate sensory processes (by increasing physiological demand) in order to examine the role of dispositional traits that may influence an individual’s ability to cognitively regulate these responses. With the use of near infrared spectroscopy, in this study we examined the influence of self-reported tolerance upon prefrontal cortex (PFC) hemodynamics and affective responses. The hemodynamic response was measured in individuals with high or low tolerance during an incremental exercise test. Sensory manipulation was standardized against metabolic processes (ventilatory threshold [VT] and respiratory compensation point [RCP]), and affective responses were recorded. The results showed that the high-tolerance group displayed a larger hemodynamic response within the right PFC above VT (which increased above RCP). The low-tolerance group showed a larger hemodynamic response within the left PFC above VT. The high-tolerance group reported a more positive/less negative affective response above VT. These findings provide direct neurophysiological evidence of differential hemodynamic responses within the PFC that are associated with tolerance in the presence of increased physiological demands. This study supports the role of dispositional traits and previous theorizing into the underlying mechanisms (cognitive vs. sensory processes) of affective responses.  相似文献

Inhibition is known to influence balance, step initiation and gait control. A specific subcomponent of inhibition, the perceptual inhibition process, has been suggested to be specifically involved in the integration of proprioceptive information that is necessary for efficient postural responses. This study aimed to investigate the inhibition requirements of planning and executing a choice step initiation task in young adults following experimental perturbation of proprioceptive information using Achilles tendon vibrations. We developed an inhibitory stepping reaction time task in which participants had to step in response to visual arrows that manipulated specific perceptual or motor inhibition according to two proprioceptive configurations: without or with application of vibrations. Performance of twenty-eight participants (mean age 21 years) showed that Achilles tendon vibrations induced an increase in attentional demands (higher reaction time and longer motor responses). Further, this increase in attentional demands did not affect specifically the different inhibitory processes tested in this reactive stepping task. It suggests that attentional demands associated with the vibratory perturbation to postural control do not lead to a shift from automatic to more attentional inhibition processes, at least in young adults.  相似文献

Reinforcement of effortful performance in a given academic task has been found to increase the subsequent performance of other academic tasks. The learned-effort hypothesis assumes that individuals learn which dimensions of task performance are correlated with reinforcement of high effort, and generalize across tasks. Therefore, reinforcement of increased effort in a given dimension of one task should result in greater generalized effort in the same dimension of transfer performance than in another dimension. In accord with this view, preadolescent learning-disabled students who received points for high reading accuracy subsequently produced more accurate drawings and stories than did students whose points had been based upon high reading speed or upon mere completion of the reading task. Students who received points for high reading speed subsequently constructed stories more quickly than did children whose points had been based upon high reading accuracy or upon reading-task completion. Consistent with the more explicit and frequent feedback for accuracy than for speed in most academic tasks, generalized accuracy was much more durable than generalized speed.  相似文献
