The influence of mental toughness on responses to feedback in snooker: A real-time examination

Two experiments investigated whether mental toughness (MT) is associated with the ability to respond to and/or overcome unwanted information during real-time sport performance. Participants were male snooker players ranging from club to professional level, and MT was measured using the MTQ48 (Clough et al., 2002). In experiment 1, players performed five break-off shots and received deceptive feedback (either positive or negative) from the researcher about their performance relative to other players. Then they performed another five break-offs. Results showed a significant decline in performance following feedback, but no interaction with the nature of feedback or MT variables. In experiment 2, feedback was delivered by a coach and yielded a significant effect on performance. Specifically, negative feedback improved performance while positive feedback impaired performance. The Life Control subscale of the MTQ48 was a significant covariate. The results suggest that negative feedback, delivered constructively by a respected figure, may act as a catalyst for performance enhancement in snooker and that this is moderated by MT.     

Does accuracy matter? A review of the consequences of accurate personality impressions as a function of context and content

What are the implications of seeing others as they see themselves? That is, does viewing others accurately have consequences, positive or negative, to relationship evaluations (e.g., liking)? To address this, the current article provides a comprehensive review of the personality accuracy literature and discusses related work from the self-verification and empathic accuracy domains. We specifically explore whether the consequences of accurate perceptions could be influenced by two key categories of moderators: the context of the impression (e.g., high vs. low stakes) and content of the impression (e.g., desirability of traits). Lastly, we discuss future directions to aid our understanding of this question.     

Interoceptive accuracy and panic

Psychophysiological models of panic hypothesize that panickers focus attention on and become anxious about the physical sensations associated with panic. Attention on internal somatic cues has been labeled interoception. The present study examined the role of physiological arousal and subjective anxiety on interoceptive accuracy. Infrequent panickers and nonanxious participants participated in an initial baseline to examine overall interoceptive accuracy. Next, participants ingested caffeine, about which they received either safety or no safety information. Using a mental heartbeat tracking paradigm, participants' count of their heartbeats during specific time intervals were coded based on polygraph measures. Infrequent panickers were more accurate in the perception of their heartbeats than nonanxious participants. Changes in physiological arousal were not associated with increased accuracy on the heartbeat perception task. However, higher levels of self-reported anxiety were associated with superior performance.     

Emotions Evoked by Viewing Pictures may Affect Temporal Aspects of Visual Processing

We examined how impression (such as safety, pleasantness, and impact), as well as emotional arousal and valence, evoked by viewing a picture affects temporal resolution of visual processing and perceived picture duration. In the first experiment as an index of temporal resolution of visual processing, we measured the noticeable duration of a monochrome picture after presenting a color picture. In the second experiment, we measured the duration of the picture presentation, which was equivalent to the duration of the presentation of a gray rectangle that should not evoke specifically safe or pleasant impressions. We found that the minimum duration in which an observer could notice a monochrome image in viewing a dangerous picture was shorter than that in viewing safe pictures. We also found that observers overestimated the duration of the picture presentation in viewing dangerous pictures. However, there was no significant correlation between the results of the two experiments. These results suggest that the basis for improvement of the temporal resolution in visual processing differs from that for the elongation of the perceived duration.     

Is Group Singing Special? Health,Well‐Being and Social Bonds in Community‐Based Adult Education Classes

Evidence demonstrates that group singing improves health and well‐being, but the precise mechanisms remain unknown. Given that cohesive social networks also positively influence health, we focus on the social aspects of singing, exploring whether improvements in health and well‐being are mediated by stronger social bonds, both to the group as a whole (collective‐bonding) and to individual classmates (relational‐bonding). To do so, seven newly formed community‐based adult education classes (four singing, N = 84, and three comparison classes studying creative writing or crafts, N = 51) were followed over seven months. Self‐report questionnaire data on mental and physical health, well‐being and social bonding were collected at Months 1, 3 and 7. We demonstrate that physical and mental health and satisfaction with life significantly improved over time in both conditions. Path analysis did not show any indirect effects via social bonding of Condition on health and well‐being. However, higher collective‐bonding at timepoint 3 significantly predicted increased flourishing, reduced anxiety and improved physical health independently of baseline levels. In contrast, relational‐bonding showed no such effects, suggesting that it is feeling part of a group that particularly yields health and well‐being benefits. Moreover, these results indicate that singing may not improve health and well‐being more than other types of activities. Nonetheless, these findings encourage further work to refine our understanding of the social aspects of community‐based adult education classes in promoting health, well‐being and community cohesion.

定量运动负荷和个性特征对动觉准确性和动作稳定性的影响

目的在于了解个性特征和定量运动负荷与同射箭运动员技术水平密切相关的肘关节动觉方位准确性和手动作稳定性的关系。研究结果表明：个性特征对肘关节动觉方位准确性和手动作稳定性的影响不显著;定量运动负荷可以使肘关节动觉方位准确性明显提高,而手动作稳定性变化不显著。本研究初步证明了韩国射箭训练中利用跑步等手段使运动员处于较高心率之下进行射准练习的方法是实用有效的。

Imagery ability classification: Commentary on «Kinaesthetic imagery ability moderates the effect of an AO+MI intervention on golf putt performance: A pilot study» by McNeill et al. (2020)

McNeill et al. (2020) recently published a study that first aimed to assess the effect of a combination of motor imagery (MI) and action observation (AO) on golf putt performance and then to determine if the evolution of this performance could be moderated by participants’ kinesthetic imagery ability. To assess golfers’ MI ability, the authors used the third version of the Movement Imagery Questionnaire. Participants notably self-estimated their kinesthetic MI ability by using a Likert-type scale, with scores ranging from 1 “very difficult to feel” to 7 “very easy to feel”. Athletes were categorized as either “poor” or “good” kinesthetic imagers, with mean scores of 4.93 and 6.63, respectively, in the intervention groups. Although a similar categorization procedure had previously been used in the literature for “good imagers”, the mean scores for “poor” imagers were much higher than those noted in previous studies evaluating the effect of MI ability on motor accuracy. Moreover, the low number of participants in the intervention group (n = 22) meant that participants were considered “poor” imagers even though their mean scores corresponded to “quite easy to feel” kinesthetic images of movements. This could notably explain the lack of differences between “poor” and “good” imagers in terms of putting performance in the intervention group. Despite these methodological limitations, the results of McNeill et al.‘s study show promising evidence for the efficacy of an AO plus MI intervention in relation to putting performance and should lead to further investigations. We suggest that research in the area of motor imagery ability include larger samples to explore, in individuals with very low imagery ability scores, the effects of the combination of AO and MI on motor performance.
