项目摘要

The two main lines of this research involve: (1) studies on the appearance mode of anticipatory response and the evaluation of adaptive process in a serial motor skill learning; (2) studies on the effects of acquisition of a different serial motor task on the appearance mode of anticipatory response in adaptive process and robustness of adaptability. The first experiment examined the effect of the type of frequency distribution of four inter-stimulus interval (ISI: 300,400, 500, 600msec). Undergraduate students (n=20) tracked in feedback control phase using a tracking task of serial patterns. The results indicated that the type of frequency distribution of anticipatory response depend on the ISI, but not on each serial position of the pattern. The second experiment examined the role of anticipatory function in both feedback and adaptive control phase for the changed serial position. Results found that for the adaptive control phase, although the anticipatory response in feedback contro … More l phase decreased, anticipatory response reduced to the number of trials for adaptive criterion after that. Using four different serial tracking tasks, third study examined the appearance mode of anticipatory response and the robustness as a criterion for evaluation of adaptability in the feedback control phase and adaptive control phases(1):changed serial position and adaptive control phase(2):changed ISI. Forty participants were randomly assigned to one of four groups (n=10 per group) in each stimulus(S)-response (R) task: forced pace tasks: S-S and S-R group ; self paced tasks :R-S and R-R group. The results showed that in the feedback control phase R-S group indicated higher accurate response than other groups. In the adaptive control phase (1) S-S group further revealed high adaptability. In the adaptive control phase (2) R-R group, which learned the contextual structure of serial pattern showed higher robust response than other groups. These results were discussed in term of sequential dependency in serial motor skill learning. Less

本研究的两条主线是：(1)系列运动技能学习中预期反应的出现方式和适应过程的评价；(2)不同系列运动任务的习得对适应过程中预期反应的出现方式和适应稳健性的影响。第一个实验考察了四个刺激间间隔(ISI：300、400、500、600毫秒)的频率分布类型的影响。被试(n=20)在反馈控制阶段采用连续模式跟踪任务进行跟踪。结果表明，预期反应的频率分布类型取决于ISI，而不是取决于模式的每个序列位置。第二个实验考察了预期函数在串联位置变化的反馈和自适应控制阶段中的作用。结果发现，在自适应控制阶段，尽管反馈控制…中的预期反应L时相减少较多，预期反应减少为适应标准后的试验次数。研究三使用四种不同的序列跟踪任务，考察了反馈控制阶段和自适应控制阶段(1)：改变串联位置和自适应控制阶段(2)：改变ISI阶段的预期反应的出现方式和稳健性作为评价适应性的标准。将40名受试者随机分为4组，每组10名，每组10名，每组10名，每组10名，每组10名，每组10名，每组10名，每组10名，每组10名，每组10名。结果表明，在反馈控制阶段，R-S组的反应准确率高于其他组。在自适应控制阶段(1)，S-S组进一步表现出高适应性。在自适应控制阶段(2)，学习序列模式背景结构的R-R组表现出比其他组更强的稳健反应。这些结果从序列依赖的角度对串联运动技能学习进行了讨论。较少
