ObjectiveIt is well-established that early visual information has an important role in human ability to play ball sports, as its correct interpretation promotes accurate predictions concerning the ball motion. Other research highlights that auditory information provides relevant cues in various sport situations. The present study combines these two lines of research with the aim to investigate the contribution of early auditory and visual information to the discrimination of shot power in sport-specific situations.DesignTwo experiments were run, one concerning soccer penalty kicks and the other concerning volleyball smashes. In both experiments there were three conditions: Audio, Audiovideo, and Video; a within subjects design was used, with the three conditions carried out in three different days and in a counterbalanced order among participants.MethodParticipants’ task was to discriminate the power of two penalties/smashes presented in rapid sequence, on the basis of a two-alternative forced choice paradigm.ResultsThe results revealed that, for both penalties and smashes, response accuracy was above chance level in all the three conditions; moreover, while for the penalties no difference among the conditions was observed, for the smashes participants were more accurate in the Audio and Audiovideo conditions compared to the Video condition. As concerns the response times, for both penalties and smashes participants were faster in the Audio and Audiovideo conditions compared to the Video condition.ConclusionsTaken together, the results suggest that the discrimination of shot power was more easily performed on the basis of early auditory information than on the basis of the respective visual information.  相似文献

Simulations were conducted to examine the effect of differential item functioning (DIF) on measurement consequences such as total scores, item response theory (IRT) ability estimates, and test reliability in terms of the ratio of true-score variance to observed-score variance and the standard error of estimation for the IRT ability parameter. The objective was to provide bounds of the likely DIF effects on these measurement consequences. Five factors were manipulated: test length, percentage of DIF items per form, item type, sample size, and level of group ability difference. Results indicate that the greatest DIF effect was less than 2 points on the 0 to 60 total score scale and about 0.15 on the IRT ability scale. DIF had a limited effect on the ratio of true-score variance to observed-score variance, but its influence on the standard error of estimation for the IRT ability parameter was evident for certain ability values.  相似文献

To determine whether and how learning is biased by competing task-irrelevant information that creates extraneous cognitive load, we assessed the efficiency of university students with a learning paradigm in two experiments. The paradigm asked participants to learn associations between eight words and eight digits. We manipulated congruity of the digits’ ink colour with the words’ semantics. In Experiment 1 word stimuli were colour words (e.g., blue, yellow) and in Experiment 2 colour-related word concepts (e.g., sky, banana). Marked benefits and costs on learning due to variation in extraneous cognitive load originating from processing task-irrelevant information were evident. Implications for cognitive load theory and schooling are discussed.  相似文献

The recent PROMETHEE-Scoring approach offers a method for generating cardinal scores through an outranking procedure utilizing Stochastic Multicriteria Acceptability and σ$$ sigma $$–μ$$ mu $$ analysis. In this paper, we illustrate some undesirable effects of this method and explore possible approaches to address them. First, we modify the original LP by inserting a new constraint that limits negative impacts caused by alternatives with low flow mean and standard deviation. Also, clustering is used to identify outliers in the decision matrix that may induce undesirable effects. A toy example demonstrates the issues and explores the proposed implementations. In addition, a numerical application is presented where a set of countries is ordered based on criteria from an economic freedom assessment. Both the numerical application and the toy example show that the propositions can improve the consistency of the results and prevent inconsistent outputs. The results include comparisons between the rank of alternatives when using purely the PROMETHEE-Scoring method, the proposed improvements, and the expected results from SMAA-PROMETHEE.  相似文献

Based on the curiosity-as-drive theory and the theory of information gaps, we argue that curiosity—that is, the desire to seek out novel information for its own sake—is highly transient, and while people may be tempted by immediate answers, they may be less motivated when they need to wait for information. Contrary to standard economic models, we predict an immediacy effect (or present bias) for information even in those cases when waiting does not affect the objective value of information. Furthermore, we argue that this immediacy effect is independent from motivated emotion-management; that is, introducing delays makes people less willing to obtain information for its own sake even when information does not elicit strong anticipatory feelings. We test these hypotheses in two pre-registered experiments (N = 2406) featuring real effort and monetary incentives and find that introducing a delay in information provision significantly reduces participants' willingness to obtain information. In Study 1, we also show that people display a stronger immediacy effect for information than for monetary rewards. In Study 2, we demonstrate that people are impatient for information regardless of how they expect to feel after receiving the information, and even when the perceived instrumental value of information remains unaffected by the delay. The strong impatience for information in both studies is consistent with the notion that curiosity acts as a drive, and as such, is highly transient.  相似文献

This study investigated the influence of cognitive interference on the detectability of concealed information in a reaction time (RT)-based concealed information test (CIT). The classical RT-based CIT was modified to interfere with response preparation, hypothesizing that this interference would enhance detection efficiency. A total of 120 participants were randomly assigned as “guilty” or “innocent” and were instructed to deny any knowledge related to a mock crime. The results revealed that guilty participants exhibited significantly longer RTs for probes than for irrelevant stimuli in both the classical and modified-CIT conditions (aka CIT effect). In contrast, innocent participants showed no difference in RTs between the probe and irrelevant stimuli under either condition. Furthermore, the modified-CIT yielded significantly higher detection efficiency than the classical-CIT. These findings signify promising advancements in the application of cognitive interventions in deception detection methodologies.  相似文献

Existing research has focused extensively on the role of emotions such as anger, fear, and enthusiasm in explaining public opinion, but less is known about the importance of disgust, an innate disease-related emotion. To study the independent and joint effects of disgust and information, I draw on the case of the COVID-19 pandemic. I demonstrate that experimentally induced incidental disgust and exposure to information about how to flatten the curve of the COVID-19 cases have distinctive effects on political, racial, and health attitudes. Independently, exposure to information affects preferences only for restrictive policies to fight the spread of the virus. In contrast, the stand-alone effect of incidental disgust, as well as its joint effect with exposure to information, are responsible for attitude change toward both pandemic-relevant and irrelevant policies, Asian minorities, and prevention measures. Importantly, the study finds that citizens respond symmetrically to disgusting stimuli and information across degrees of political awareness, ideology, partisan affiliation, and trait authoritarianism. The results draw attention to the far-reaching implications of disgust on public opinion under threatening conditions.  相似文献

There is scant research on the validity of personality assessment games in selection situations. Therefore, in two experimental simulated selection studies, the construct validity of an assessment game developed to assess honesty-humility was tested. Both studies found no differences between a control condition and a simulated selection condition on honesty-humility game scores. Moreover, convergent and discriminant validity with self-reported personality were not affected by the manipulation. We obtained mixed evidence that individual differences in dispositional insight and the ability to identify criteria influenced the validity of the game. As the validity of the personality assessment game was not significantly affected in the simulated selection context, our findings may imply that well-designed personality assessment games can be used for high-stakes selection assessments.  相似文献

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L1 regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.  相似文献
