Abstract This study examined discrepancies between subjective and objective measures of state anxiety as a function of test anxiety in undergraduates. Under evaluative stress conditions, state anxiety was assessed in terms of (a) self-reported cognitive and somatic anxiety, (b) behavioral reactivity (motor and facial tension, avoidance comments and avoidance of eye contact), (c) physiological arousal (heart rate and skin resistance), and (d) cognitive and motor task performance. Participants high in test anxiety showed disproportionately greater self-reported than objective state anxiety. In contrast, those low in test anxiety showed lower self-reported than objective anxiety. The high- and the low-test-anxiety groups differed only in self-reported emotional reactivity. In line with current cognitive theories of anxiety, overestimation of reactivity in high-test anxiety, as well as underestimation in low-test anxiety, are conceptualized as a hypervigilance bias and an avoidance bias, respectively, in processing internal cues, i.e., prioritization and inhibition of attention to one's own behavioral and physiological signs of distress. 相似文献

Self-consciousness during early adolescence has been explained as an outcome of adolescent egocentrism, in which adolescents create an imaginary audience (IA) of attentive, critical peers. The possibility that such self-consciousness might result from contact with peers who are more attentive and critical than those encountered during childhood or adulthood has not been considered. Study I tested whether young adults, who are not theoretically susceptible to IA, could be made to receive high scores on IA and self-consciousness measures by having them complete a procedure in 1 of 3 laboratory conditions—a critical audience, a noncritical audience, or no audience. However, participants in the critical-audience condition received significantly lower IA and self-consciousness scores than participants in the no-audience condition did. Study 2 tested whether the directions given to Study I participants might have been responsible for the unexpected findings. Results indicated that participants instructed to give mature-sounding responses received lower IA/self-consciousness scores than did those asked to report their honest opinions. Together, the results of Studies 1 and 2 indicated that survey measures of IA are subject to demand characteristics and highlighted the need to interpret with caution age differences in IA as traditionally assessed. 相似文献

The authors’ aim was to determine which variables allow for the characterization of motor balance behavior. Traditional measures and nonlinear measures of center of pressure (COP; n = 30) and kinematics (n = 10) were tested in their absolute and relative consistency in a 30-s standing balance task protocol under stable and unstable conditions. Regarding COP variables, mean velocity (mVel), permutation entropy (PE) and detrended fluctuation analysis (DFA) exhibited high consistency between trials and ranked individuals more accurately compare with other metrics. In the kinematic signal mVel, PE and DFA had good intrasession reliability values in unstable conditions. Overall, the intrasession reliability values were better in the unstable condition than in the stable condition and the measures calculated using derived data had better intrasession reliability values. In conclusion, mVel, PE, and DFA allow for the good characterization of motor balance behavior in a simplified protocol where velocity time series are analyzed. 相似文献

Up until now, no really short instrument that measures the six personality dimensions of the HEXACO model has been available. In two studies, I report the construction of the Brief HEXACO Inventory (BHI), which represents the 24 HEXACO facets with 1 item per facet (i.e., 4 items per domain) and which takes approximately 2–3 min to complete. Although characterized by relatively low alpha reliability, its test–retest stability, self-other agreement, and convergent correlations with full-length scales are relatively high and its validity loss is only modest. Correcting for attenuation using a weighted average of alpha reliability, test–retest stability, and self-other agreement, the BHI re-estimates the original construct validity correlations of the HEXACO-PI-R with relatively great accuracy. 相似文献

Fear of movement/(re)injury is assumed to contribute to the development and maintenance of chronic low back pain (CLBP) in a subgroup of patients. Studying fear of movement/(re)injury with implicit attitude measures, without the awareness of the patient, might be a valuable addition to self‐report questionnaires. The aims of the current study were to investigate whether CLBP patients demonstrate more implicit fear of movement/(re)injury than healthy controls, and whether 2 implicit measures are related to each other, and to an explicit self‐report measure of fear of movement/(re)injury. A group of 66 CLBP patients and 30 healthy controls took part in this study. In addition to self‐report questionnaires, fear of movement/(re)injury was implicitly assessed by the Extrinsic Affective Simon Task (EAST) and the Go‐No‐Go‐Association Task (GNAT) that aimed to determine the association between back‐stressing movements and the evaluation “threatening”. On both implicit tasks it was found that neither CLBP patients nor healthy controls demonstrated implicit fear of movement/(re)injury, and that CLBP patients did not differ from healthy controls in their level of implicit fear of movement/(re)injury. In general, no associations were found between the EAST and the GNAT, or between implicitly measured and self‐reported fear of movement/(re)injury. One major caveat in drawing inferences from these findings is the poor reliability of these implicit measures. Research towards the psychometric properties of these measures should first be expanded before modifying, and applying, them to more complex domains such as fear of movement/(re)injury. 相似文献

Current methods of assessing children’s physiological “stress reactivity” may be confounded by psychomotor activity, biasing estimates of the relation between reactivity and health. We examined the joint and independent contributions of psychomotor activity and challenge reactivity during a protocol for 5- and 6-year-old children (N = 338). Measures of parasympathetic reactivity (respiratory sinus arrhythmia [RSA]) and sympathetic reactivity (preejection period [PEP]) were calculated for social, cognitive, sensory, and emotional challenge tasks. Reactivity was calculated relative to both resting and a paired comparison task that accounted for psychomotor activity effects during each challenge. Results indicated that comparison tasks themselves elicited RSA and PEP responses, and reactivity adjusted for psychomotor activity was incongruent with reactivity calculated using rest. Findings demonstrate the importance of accounting for confounding psychomotor activity effects on physiological reactivity. 相似文献

According to life history theory, environmental cues indicating that one's future survivability is low increase reproductive effort. This suggests that exposure to low survivability cues will increase people's preparedness to engage in sex. However, according to sexual selection theory and parental investment theory, evolutionary pressures favored a more conservative sexual strategy among women compared to men. We therefore hypothesized that men, but not women, would respond to low survivability cues with increased sexual preparedness. Accordingly, both subliminal and supraliminal death primes (as compared with control primes) led men, but not women, to exhibit increased physiological arousal in response to sexual images (Study 1), and stronger approach-oriented behavioral responses to sexual images (Study 2). Theoretical implications for life history theory are discussed. 相似文献

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments. 相似文献

This research examined the benefits of interpreting physiological arousal as a challenge response on practice and actual Graduate Record Examination (GRE) scores. Participants who were preparing to take the GRE reported to the laboratory for a practice GRE study. Participants assigned to a reappraisal condition were told arousal improves performance, whereas control participants were not given this information. We collected saliva samples at baseline and after the appraisal manipulation, which were then assayed for salivary alpha amylase (sAA), a measure of sympathetic nervous system activation. Reappraisal participants exhibited a significant increase in sAA and outperformed controls on the GRE-math section. One to three months later, participants returned to the lab and provided their score reports from their actual GRE. Again, reappraisal participants scored higher than controls on the GRE-math section. These findings illuminate the powerful influence appraisal has on physiology and performance both in and out of the laboratory. 相似文献
