OBJECTIVE
To assess age differences in the costs of language planning and production.
METHODS
A controlled sentence production task was combined with digital pursuit rotor tracking. Participants were asked to track a moving target while formulating a sentence using specified nouns and verbs and to continue to track the moving target while producing their response. The length of the critical noun phrase (NP) as well as the type of verb provided were manipulated.
RESULTS
The analysis indicated that sentence planning was more costly than sentence production, and sentence planning costs increased when participants had to incorporate a long NP into their sentence. The long NPs also tended to be shifted to the end of the sentence, whereas short NPs tended to be positioned after the verb. Planning or producing responses with long NPs was especially difficult for older adults, although verb type and NP shift had similar costs for young and older adults.
DISCUSSION
Pursuit rotor tracking during controlled sentence production reveals the effects of aging on sentence planning and production.
目的
评估语言规划和产生的成本在年龄上的差异。
方法
将受控句子产生任务与数字追踪旋转器相结合。要求参与者在制定句子时使用指定的名词和动词来跟踪移动目标，并在生成响应时继续跟踪移动目标。操纵关键名词短语（NP）的长度和提供的动词类型。
结果
分析表明，句子规划比句子产生更昂贵，并且当参与者必须将长 NP 纳入句子中时，句子规划成本会增加。长 NP 也往往被移到句子的末尾，而短 NP 往往位于动词之后。对于老年人来说，规划或生成带有长 NP 的反应尤其困难，尽管动词类型和 NP 移位对年轻人和老年人都有类似的成本。
讨论
在受控句子产生过程中追踪旋转器揭示了衰老对句子规划和产生的影响。
