The aim of the present study was to investigate the effects of cognitive-linguistic variables and language experience on behavioral and kinematic measures of nonword learning in young adults. Group 1 consisted of thirteen participants who spoke American English as the first and only language. Group 2 consisted of seven participants with varying levels of proficiency in a second language. Logistic regression of the percent of correct productions revealed short-term memory to be a significant contributor. The bilingual group showed better performance compared to the monolinguals. Linear regression of the kinematic data revealed that the short-term memory variable contributed significantly to movement coordination. Differences were not observed between the bilingual and the monolingual speakers in kinematic performance. Nonword properties including syllable length and complexity influenced both behavioral and kinematic performance. The findings supported the observation that nonword repetition is multiply determined in adults.
本研究的目的是调查认知语言变量和语言经验对年轻成年人非词学习的行为和运动学指标的影响。第一组由13名以美式英语为第一且唯一语言的参与者组成。第二组由7名第二语言熟练程度各异的参与者组成。对正确产出百分比进行逻辑回归分析显示，短期记忆是一个重要因素。与单语者相比，双语组表现更好。对运动学数据进行线性回归分析表明，短期记忆变量对运动协调有显著影响。在运动学表现方面，双语者和单语者之间未观察到差异。包括音节长度和复杂度在内的非词属性影响了行为和运动学表现。这些发现支持了以下观察结果：在成年人中，非词重复是由多种因素决定的。
