title: Experts’successful psychomotor performance was characterized by effective switch of motor and attentional control abstract: Objectives:This study proposed that Mu (8–13 Hz) and SMR (12–15 Hz) readings in the sensorimotor corticalarea can be used to investigate the cognitive mechanisms underlying optimal motor performance.Design:This study used a within-subject design.Method:Forty expert golfers were recruited to perform 60 putts while their EEGs were recorded. The puttingdistance was chosen to ensure that approximately 50% of all putts would be missed so that there was a need forconstant adjustments to be made during performance. Successful performance was defined as the ball going inthe hole.Results:(a) Lower Mu power in Cz, and alpha power in Pz and Oz were observed for successful performancescompared with unsuccessful performances at T1 (−2000∼−1000 ms); (b) Higher SMR power in Cz was ob-served for successful performances relative to unsuccessful performances at T2 (−1000∼0 ms).Conclusions:Thesefindings not only support the multi-action plan model (MAP) and the psychomotor efficiencyhypothesis, but also reveal the temporal dynamics of the cognitive mechanisms in an optimal-controlled state.

Seeking positive strengths in buffering athletes’life stress- burnout relationship: The moderating roles of athletic mental energy

title: Seeking positive strengths in buffering athletes’life stress- burnout relationship: The moderating roles of athletic mental energy abstract: In search of positive strengths that bolster athletes’ reaction to stress, the purpose of this study was to examine the moderating effects of athletic mental energy on the athletes’ life stress–burnout relationship. This study recruited two samples (Study 1 = 230; Study 2 = 159) and administered the College Student-Athlete’s Life Stress Scale (CSALSS; Lu et al., 2012), Athletic Mental Energy Scale (AMES; Lu et al., 2018), and Athlete Burnout Questionnaire (ABQ; Raedeke and Smith, 2001). Two separate hierarchical multiple regression analyses found that the emotional and cognitive components of athletic mental energy moderated the athletes’ life stress–burnout relationship across the two studies. Results provided the initial evidence that athletic mental energy can be positive strengths in buffering the stress–burnout relationship. Theoretical implications, limitations, practical applications, and future research directions are discussed.

不同途徑之同儕教學模式對迷你網球學生內在動機之影響

title: 不同途徑之同儕教學模式對迷你網球學生內在動機之影響 abstract: 本研究旨在探討藉由不同途徑之同儕教學模式對迷你網球初學生內在動機之影響與差異。受試者為臺北市文山區某國小四年級學生，實驗組26位、控制組28位，共54位。研究為期6週的迷你網球學習，每週兩次，每次40分鐘共計12次教學。實驗組採教師先指導，再讓學生進行同儕教學（受過訓練之同儕教學TPT）；控制組教師不介入指導並以教學卡做為教學媒介，再讓學生進行同儕教學（未受過訓練的同儕教學UPT）。研究工具以內在動機量表為研究工具進行前中後測驗。所得資料進行單因子重複量數變異數分析與共變數分析。研究結果顯示兩班學生均因教學實驗次數增加，而使內在動機各構面均有顯著提升。但兩組相較之下，內在動機並無顯著差異。雖然於本研究中兩班內在動機無顯著差異，但也顯示了未受過訓練的同儕教學同樣會使該班學生提升其內在動機。在未來研究上可在同儕教學中採用其他心理變項或以不同教師自主支持型態探討學生之情境動機或學習歷程。

Exercise type relates to inhibitory and error processing functions in older adults

title: Exercise type relates to inhibitory and error processing functions in older adults abstract: This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.
