Choking under the pressure of a positive stereotype: gender identification and self-consciousness moderate men's math test performance

Choking under pressure occurs when an individual underperforms due to situational pressure. The present study examined whether being the target of a positive social stereotype regarding math ability causes choking among men. Gender identification and self-consciousness were hypothesized to moderate the effect of math-gender stereotypes on men's math test performance. Men high in self-consciousness but low in gender identification significantly underperformed when exposed to gender-relevant test instructions. No significant effects were found under a gender-irrelevant condition. These findings are discussed in the contexts of research on stereotype threat, stereotype lift, and choking under pressure.     

Predicting performance and performance satisfaction: mindfulness and beliefs about the ability to deal with social barriers in sport

This research investigates the role of beliefs about the ability to deal with specific social barriers and its relationships to mindfulness, football performance, and satisfaction with one's own and team performance. Study 1 aimed at eliciting these social barriers. Study 2 tested (i) whether self-efficacy referring to social barriers would predict performance over and above task-related self-efficacy and collective efficacy and (ii) the mediating role of self-efficacy to overcome social barriers in the relationship between mindfulness and performance. Participants were football (soccer) players aged 16–21 years (Study 1: N = 30; Study 2: N = 101, longitudinal sample: n = 88). Study 1 resulted in eliciting 82 social barriers referring to team, peer leadership, and coaches. Study 2 showed that task-related self-efficacy and collective efficacy explained performance satisfaction at seven-month follow-up, whereas self-efficacy referring to social barriers explained shooting performance at seven-month follow-up. Indirect associations between mindfulness and performance were found with three types of self-efficacy referring to social barriers, operating as parallel mediators. Results provide evidence for the role of beliefs about the ability to cope with social barriers and show a complex interplay between different types of self-efficacy and collective efficacy in predicting team sport performance.     

The impact of working memory training on near and far transfer measures: Is it all about fluid intelligence?

This randomized control study investigates the effects of working memory (WM) training on near (similar WM memory tasks) and far (math problem-solving processes and accuracy tasks) transfer in children aged 7 to 11 years who vary in fluid intelligence. Participants were randomly assigned to either a control group or one of two WM training conditions (repeated practice vs. cued recall). ?When compared to the control condition, the results show that the cued recall condition yields higher post-test scores for the far transfer measures, whereas the repeated practice condition yields higher scores for the near transfer? measures. However, these finding are qualified by significant treatment × fluid intelligence interactions. Thus, improvements in WM and related measures, as well as the positive transfer in learning outcomes, are moderated by fluid intelligence.     

解读“反胜为败”的现象：一个“Choking”过程理论

运动员关键时刻以先赢后输的形式丢掉冠军的现象越来越多地发生在现代竞技体育比赛中。心理学上称之为压力下的“Choking”,并定义为压力条件下一种习惯的运动执行过程发生衰变的现象。对于“Choking”的研究开始于八十年代初中期,迄今为止,主要有干扰假说和自动执行假说解释其发生机制。但由于现有的假说过于简单,理论的研究一直不能为实践防治“Choking”提供可行的措施。本文基于笔者多年来的研究积累,就这一空缺,提出并讨论了一个“Choking”过程理论。该理论把“Choking”作为一个过程来讨论,包括引起因素、认知过程、应付过程和运动过程。根据过程理论,本文讨论了“Choking”发生机制。在此基础上,提供了防止“Choking”发生的具体可行性措施。     

Stereotype internalization and women’s math performance: The role of interference in working memory

It has long been argued that stigmatized individuals can ultimately internalize the stereotype alleging their inferiority. The present article investigated whether the internalization of the reputation of math inferiority that targets women can affect their math performance and whether this influence is caused by a disruption of working memory. A first study showed that stereotype endorsement had a significant impact on women’s statistic performance by lowering their self-evaluation of math ability even when controlling for prior achievement. A second study was designed to assess the possibility that the lower math performance displayed by women with low self-evaluation of math ability was due to interference in working memory. Using a dual task paradigm, this study showed that indeed women with low math self-evaluation displayed more errors and spent more time solving additions than women with high math self-evaluation, but mainly on difficult items of the dual task. The findings, which are congruent with an explanation in terms of a temporary disruption of working memory, are discussed.     

Encoding and representation of simultaneous and sequential arrays in visuospatial working memory

The effect of presentation type on organization in visuospatial working memory (VSWM) was examined. Stimuli were presented sequentially or simultaneously at study, and participants made same/different judgements at test. The test array varied in four different spatial configuration conditions: one featuring no changes from study, one in which two items switched, one in which the same array repeated but in a different location, and one in which a completely novel test stimulus appeared. Results indicated the use of a global configuration for both simultaneous and sequential presentations and showed increased impairment of item-level knowledge with sequential presentations. Overall, these results support the use of a global configuration organization as a fundamental aspect of VSWM processing.     

Influence of Response Similarity on Interference in Perceptual Motor Learning

Motor interference was measured in terms of average response time in sorting 15 pairs of cards, each pair containing words which were either unrelated or identical but printed in different colors. The two words of each pair were used in labeling two cubicles in such a way that they were apart by 0, 1, 2, or 3 intervening cubicles in quasirandomly chosen directions. Interference was inversely related to response similarity, but this relationship may not appear in the absence of sufficient stimulus similarity. The findings are interpreted in the light of a hypothesis which views motor interference as a tendency for responses to deflect from their own courses and be pulled towards those of other responses with which they are at conflict.     

Behavioural evidence for separating components within visuo-spatial working memory

Several different sources of evidence support the idea that visuo-spatial working memory can be segregated into separate cognitive subsystems. However, the nature of these systems remains unclear. Recently we reported data from neurological patients suggesting that information about visual appearance is retained in a different subsystem from information about spatial location. In this paper we report latency data from neurologically intact participants showing an experimental double dissociation between memory for appearance and memory for location. This was achieved by use of a selective dual task interference technique. This pattern provides evidence supporting the segregation of visuo-spatial memory between two systems, one of which supports memory for stimulus appearance and the other which supports memory for spatial location.     

Dimension-based working memory-driven capture of visual selection

We studied attentional capture by dimensional cueing of visual objects. Participants received two dimension cues, one relevant for a memory test and the other relevant for an attention test. Performance in the attention task was impaired on incongruent trials (i.e., when the relevant dimensions for memory and attention did not match) relative to congruent trials. Dimensional cueing effects were enhanced when the cued dimension was held “online” in working memory through the trial, compared to when the cued dimension did not have to be held in memory. The findings demonstrate that dimensional cueing of visual selection can occur in a largely automatic manner, with working memory exerting a strong modulatory influence. We discuss the implications of these findings for understanding the interaction between memory and attention.     

Gesturing saves cognitive resources when talking about nonpresent objects

In numerous experimental contexts, gesturing has been shown to lighten a speaker's cognitive load. However, in all of these experimental paradigms, the gestures have been directed to items in the "here-and-now." This study attempts to generalize gesture's ability to lighten cognitive load. We demonstrate here that gesturing continues to confer cognitive benefits when speakers talk about objects that are not present, and therefore cannot be directly indexed by gesture. These findings suggest that gesturing confers its benefits by more than simply tying abstract speech to the objects directly visible in the environment. Moreover, we show that the cognitive benefit conferred by gesturing is greater when novice learners produce gestures that add to the information expressed in speech than when they produce gestures that convey the same information as speech, suggesting that it is gesture's meaningfulness that gives it the ability to affect working memory load.     

To err again is human: exploring a bidirectional relationship between pressure and performance failure feedback

ABSTRACT

Background and Objectives: While the potentially negative effects of pressure on skilled performance have been well studied in laboratory-based research, theoretically driven questions based on real-world performance data are lacking.

Design: We aimed to test the predictions of the newly developed Attentional Control Theory: Sport (ACTS), using archived play-by-play data from the past seven seasons of the National Football League (American Football).

Methods: An additive scoring system was developed to characterize the degree of pressure on 212,356 individual offensive plays and a Bayesian regression model was used to test the relationship between performance, pressure and preceding negative outcomes, as outlined in ACTS.

Results: There was found to be a clear increase in the incidence of failures on high pressure plays (odds ratio?=?1.20), and on plays immediately following a previous play failure (odds ratio?=?1.09). Additionally, a combined interactive effect of previous failure and pressure indicated that the feedback effect of negative outcomes was greater when pressure was already high (odds ratio?=?1.10), in line with the predictions of ACTS.

Conclusions: These findings reveal the importance of exploring momentary changes in pressure in real-world sport settings, and the role of failure feedback in influencing the pressure-performance relationship.

工作记忆对动态范式中基于客体的返回抑制的影响

采用双任务干扰范式探讨了工作记忆对动态范式中基于客体的返回抑制的影响。三个实验分别考察了在言语、空间和视觉工作记忆负载条件下基于客体的返回抑制效应,结果发现只有在空间工作记忆负载条件下,动态范式中的返回抑制才受到损害。这表明空间工作记忆不但在静态范式中的IOR信息的维持和更新中起着重要的作用,在动态范式中的IOR信息的维持和更新中同样起着重要的作用。同时也为动态范式中基于客体的返回抑制的空间抑制动态更新说提供了新的证据
