Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.  相似文献

Abstract

The aim of this study was to investigate the effects of state and trait anxiety on physical performance under both neutral and stressful conditions. In Study I, 43 male and female track athletes answered the State-Trait Anxiety Inventory and twice underwent ergometric testing in the physiology laboratory after receiving a neutral or a stress-inducing instruction. In Study II, these 43 runners completed the state scale shortly before a test run in a practice session and once again just before the start in an official competition. Results showed a significant increase in self-reported state anxiety under the stress condition in both the laboratory and the field setting. At the same time, the mean physical performance, measured as physiological performance parameters (maximum oxygen intake, physical work capacity) or as running performance, significantly deteriorated under stress. The induced stress affected the heart rate in addition to the mere physical work load, with no sign of compensation occurring during the entire period of ergometric testing. Effects of anxiety on performance were tested by separate 2(trait) × 3(state) ANOVAs for each situation. For both laboratory situations, and for the practice situation as well, no significant relationships, neither linear nor nonlinear, were detected. In the competition situation, however, an inverted-U relationship was found in the low trait-anxious subgroup.  相似文献

Abstract

Subjects were required to detect either an angry or a happy target face in a stimulus array of 12 photographs. It was found with neutral distractor faces that those high in trait anxiety detected angry faces faster than did low trait-anxious subjects, but the two groups did not differ in their speed of detection of happy targets. In addition, high trait-anxious subjects detected happy target faces slower than low trait-anxious subjects when the distractor faces were angry. Comparable findings were obtained whether or not there was anxious mood induction. It was concluded that high trait-anxious individuals have facilitated detection and processing of environmental threat relative to low trait-anxious subjects, which enhance performance when the target is threatening, but which impair performance when the distractors are threatening.  相似文献

In experiment 1, the attentional demands of two fine (finger movements) and two gross (arm movements) motor tasks were empirically determined. In experiment 2, the effects of test condition (stress) and anxiety trait on motor performance were analyzed. A significant interactive effect appeared: the performance of high-trait-anxious subjects was impaired under evaluative conditions in fine and/or attentionally demanding tasks, but not in gross and attentionally simple tasks. As test conditions and anxiety trait have proved to arouse physiological alterations and aversive cognitive representations, the selective performance impairment found can be attributed to interferences on finger effectors or proprioceptors and to attentional overload, respectively.  相似文献

The current study investigated the effects of trait worry, a subcomponent of trait anxiety, on the process of updating information in working memory (WM). A leading theory on anxiety and executive functions, attentional control theory (ACT), states that anxiety is not related to WM updating in emotionally neutral situations. Previous research, however, has focused almost exclusively on WM span tasks that primarily emphasised storage, rather than the updating of WM representations. Moreover, few studies have directly examined the effects of trait worry. In this study, 116 subjects performed a WM updating task that required the memorisation of short lists of words and the within-trial removal of some of these items from WM. Results indicated that levels of trait worry were not related to word-span performance, but were related to performance on trials that required subjects to effectively update WM. Moreover, these effects were observed only for trait worry, not for levels of anxious arousal or comorbid levels of dysphoria. These results support the hypothesis that trait worry is related to WM updating performance and thereby extend ACT in new directions.  相似文献

The impact of trait anxiety and perceptual load on selective attention was examined in a fear conditioning paradigm. A fear-conditioned angry face (CS+), an unconditioned angry face (CS-), or an unconditioned face with a neutral or happy expression were used in distractor interference and attentional probe tasks. In Experiments 1 and 2, participants classified centrally presented letters under two conditions of perceptual load. When perceptual load was high, distractors had no effect on selective attention, even with aversive conditioning. However, when perceptual load was low, strong response interference effects for CS+ face distractors were found for low trait-anxious participants. Across both experiments, this enhanced distractor interference reversed to strong facilitation effects for those reporting high trait anxiety. Thus, high trait-anxious participants were faster, rather than slower, when ignoring CS+ distractors. Using an attentional probe task in Experiment 3, it was found that fear conditioning resulted in strong attentional avoidance in a high trait-anxious group, which contrasted with enhanced vigilance in a low trait-anxious group. These results demonstrate that the impact of fear conditioning on attention is modulated by individual variation in trait anxiety when perceptual load is low. Fear conditioning elicits an avoidance of threat-relevant stimuli in high trait-anxious participants.  相似文献

Fifty-three national level cyclists completed competitive rides under both laboratory and field conditions to investigate the relationship between pre-competition anxiety and performance. A total of 39 males and 14 females participated in the study, ranging in age from 19 to 26. The objectives of the study were to, (a) measure the relationship between state anxiety and performance, (b) investigate differences in the anxiety-performance relationship under laboratory versus field conditions, and (c) examine the effect of trait anxiety on the state anxiety-performance relationship. State anxiety was measured using the Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Vealey, & Burton, 1990), and trait anxiety with the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, & Lushene, 1970). Results indicated that anxiety was strongly correlated with performance on the field test, but that the anxiety-performance relationship was weaker under laboratory conditions. Results also showed that trait anxiety interacted with the relationship, as low and high trait-anxious subjects had differential response patterns to pre-competition anxiety. The findings are discussed in terms of their relevance for both practitioners and researchers.  相似文献

Abstract

Normals high, medium, and low in trait anxiety performed two encoding tasks (one predominantly data-driven and the other conceptually driven) on threat-related and neutral words, followed by tests of word completion, cued recall, and free recall. Memory performance indicated the existence of negative memory biases in the high trait-anxious group, but it was generally not possible to decide whether the biases were associated with trait anxiety rather than with depression. The biases were obtained mainly when there was a match between the processes at encoding and those at the time of test, whether the matching processes were predominantly data-driven or conceptually driven. Implications of these findings for implicit and explicit memory biases associated with high trait anxiety are discussed.  相似文献

Attentional biases for threat stimuli were assessed in high and low trait anxious subjects (n = 66) using a probe detection task. To examine the effects of trait anxiety and situational stressors, each subject was tested three times: Under no stress, laboratory-induced stress, and examination-induced stress. To evaluate the role of awareness, half the word stimuli were presented very briefly (14 msec) and masked, and the other half were presented for 500 msec without a mask. Results showed that high trait anxious subjects under exam stress showed an attentional bias towards unmasked threat stimuli compared with low trait subjects. This effect was not found under lab-induced stress, suggesting that the attentional bias for unmasked threat in high trait subjects may be a function of a prolonged stressor, rather than a transient increase in state anxiety. The results from the masked exposure condition were not predicted; high trait anxious subjects shifted attention towards the spatial location of threat words despite lack of awareness of their lexical content, but this bias was only apparent in the no-stress condition. The results are discussed in relation to recent cognitive theories of anxiety.  相似文献

The interaction model of anxiety was examined by assessing both state and trait anxiety in 64 male military personnel on a Basic Parachutist Course. Two separate tests of the interactional model of anxiety were conducted, involving physical danger and social evaluation situations. The same subjects participated in both studies. In both physical danger and social evaluation studies, measures of state anxiety and cognitive appraisal (perception) of anxiety were obtained in both high-stress and non-stress conditions. Measures of social evaluation and physical danger trait anxiety were obtained in a low-stress condition. The interactional model was strongly supported for the physical danger situation. As predicted, high physical danger trait anxiety subjects experienced greater increases in state anxiety than low physical danger subjects proceeding from the non-stress to the high stress physical danger condition. The interaction model was not supported in the social evaluation situation; although not significant, mean levels of state anxiety were in the predicted direction. Results are discussed in the context of person perception and the need for testing personality models in realistic field settings.  相似文献

Abstract

Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety.  相似文献

Abstract

The purpose of this paper was to briefly review the traditional existing theories attempting to explain the relationship between anxiety and motor performance and then suggest some future directions for research. Specifically, a review of drive theory and the inverted-U hypothesis led to the conclusion that due to methodological, conceptual and interpretive problems, these explanations for the anxiety-performance relationship are overly simplistic and lack heuristic value. Future research should focus on the interaction of psychobiological states as they relate to motor performance. Some specific suggestions include more precision in the measurement of anxiety as a multidimensional construct which includes psychophysiological, cognitive, and affective components. In addition, individual differences need to be recognized with intraindividual comparisons replacing between-subject comparisons. Hanin's zone of optimal functioning is offered as one such approach. Finally, more sensitivity and precision is needed in the measurement of performance by employing both qualitative and quantitative methodologies.  相似文献

Previous research has established that anxiety patients demonstrate a cognitive bias that selectively favours the processing of threat related information. The current experiment employs a variant of a well established colour naming paradigm to address three issues concerning the nature of this anxiety linked pattern of selective processing. First, by considering non-clinical subjects and employing an experimental design capable of dissociating the influence of state and trait anxiety, the current study addresses the hypothesis that state anxiety elevations will elicit differential patterns of selectivity in high and low trait anxious subjects. Second, by presenting stimulus materials within or outside awareness, the study addresses the hypothesis that these processing biases occur automatically, without requiring the use of consciously mediated strategies. Third, by including both emotionally valenced stimulus materials which are related to, and which are unrelated to, the particular source of stress experienced by the subjects, the experiment addresses the hypothesis that such anxiety linked processing biases will be restricted to materials falling within the domain of current personal concern. The results of the present study clearly demonstrate that these three issues are not independent. Fundamentally different patterns of anxiety linked selective processing were observed when stimuli were presented outside awareness, permitting only automatic cognitive processing, and when stimuli were presented within awareness, permitting the use of consciously mediated strategies. The relative roles played by state and trait variables, and the degree to which these effects were influenced by the personal relevance of the stimulus materials, differed in each case. The implications of these findings for future research in this field are discussed.  相似文献

Weinberg and Hunt (1976) demonstrated that high- and low-anxious subjects differed in their patterning of neuromuscular energy in performance under failure feedback. The present study extends these findings to conditions that involve success feedback. The Sport Competition Anxiety Test and State-Trait Anxiety Inventory were administered to distinguish A-State and A-Trait subjects, while EMG indicated qualitative aspects of throwing. High-and low-trait anxiety subjects received either success, failure, or no feedback. High-anxious subjects performed best under success feedback, and low-anxious subjects performed best after failure feedback. High-anxious subjects used more EMG energy before, during, and after the throw in all conditions, and success feedback was beneficial for high-anxious subjects. The results are discussed in terms of the inter-relationships between efficiency of neuromuscular energy, motor performance, and state anxiety.  相似文献

Half of the 56 subjects (n = 28) performed 15 pre-treatment trials on a stabilometer, then six more with an audience of three faculty (Group 1), the other half performed the same task with no audience (Group 2). Subjects completed the State-Trait Anxiety Inventory prior to and after the treatments. Orthogonal contrasts indicated that Group 1 (audience) post State-anxiety was significantly different from its own pre-State-anxiety and significantly different from Group 2 (no audience) on post-State-anxiety. It was concluded that the State-Trait Anxiety Inventory is an appropriate measure of trait and state anxiety in studies of motor performance.  相似文献

Abstract

Three experiments are reported which examine attentional bias in high trait-anxious, low trait-anxious, and repressor subjects. Measures of interference did not provide consistent results. However, negative priming effects suggested that high trait-anxious subjects had difficulty inhibiting threat-related information, as well as nonthreat-related distracting information under conditions of attentional search. There was some evidence that individuals with a repressive coping style were particularly efficient in inhibiting threat-related information. It is suggested that defective inhibition of distracting information may be an important mechanism in understanding the cognitive basis of anxiety.  相似文献

Research and theory suggest that anxious people employ cognitive control on a relatively late and transient basis. This tendency may impair emotion regulation that depends on early, persistent implementation of cognitive control. We examined whether anxious people could be trained to apply cognitive control proactively (i.e., in advance of goal-related action) and whether such training limited anxiety’s rise during stress. In Study 1, 96 high trait-anxious participants completed proactive or reactive training followed by the Trier Social Stress Test (TSST) with measurement of subjective anxiety, heart rate, and skin conductance level (SCL). In Study 2, 59 high trait-anxious participants completed a proactive or no-instruction training for 4 days and then completed the TSST. For Study 2 but not Study 1, the proactive versus control training was associated with lower stress-related increases in subjective anxiety and heart rate, but not sympathetically mediated SCL. Exercising proactive control may leverage the parasympathetic nervous system to inhibit the escalation of anxious arousal during stress.  相似文献

The purpose of this study was to ascertain the motivational effects of positive verbal reinforcement on the performance of a qualitative task. Male subjects performed on a task consisting of 24 slides that allowed them to test their decision-making abilities in simulated situations. Subjects performed under one of five noncontingent verbal reinforcement ratios (.00, .25, .50, .75, or 1.00). Subjects' accuracy and reaction times to each of the 24 slide stimuli were recorded and transformed into a total performance index. In line with an inverted-U hypothesis, it was hypothesized that if motivational effects of positive verbal reinforcement exist, they should induce a curvilinear relationship between reinforcement ratio and performance. This hypothesis was supported by the results of a trend analysis that showed that only the quadratic curvilinear term was significant. Inspection of means revealed the presence of an inverted-U curve such that performance gradually increased from ratio 0 and reached a maximum at ratio .50, following which a decrease in performance was obtained for ratios .75 and 1.00. Results support a motivational interpretation of the effects of positive verbal reinforcement on performance. Findings are discussed in light of the interaction between motivational and attentional processes.  相似文献
