本实验评估了有大量产前酒精暴露史的儿童的运动反应程序和运动时间。将7 ~ 17岁的酒精暴露儿童分为两组：胎儿酒精综合征（FAS: n=9）和PEA患儿（PEA: n=19），但不具有FAS的定义特征。将FAS和PEA儿童与非酒精暴露儿童（NC: n=23）在完成简单反应时间任务（RT单独条件）和反应加运动任务（RT+运动条件）两项任务时进行比较。这个动作包括对一个迫切的刺激信号做出反应，并按一定的顺序按下三个目标按钮。参与者在RT单独和RT+Move反应条件下分别完成了24个试验。结果显示，FAS组、PEA组和NC组在单独RT条件下的表现无显著差异。然而，在RT+Move条件下，FAS组产生的RTs明显长于PEA组和NC组，其产生的RTs相当。FAS组在移动到所有三个目标时也产生了显着较慢的运动时间，而运动时间变异性作为组的函数没有显着差异。观察结果表明，FAS患儿在反应规划和动作时间产生方面存在缺陷。
The present experiment assessed motor response programming and movement time in children with histories of heavy prenatal alcohol exposure (PEA). Alcohol-exposed children between the ages of 7 and 17 years were classified into two groups: Fetal Alcohol Syndrome (FAS: n=9) and children with PEA (PEA: n=19) but who did not have the defining characteristics of FAS. The FAS and PEA children were compared with non–alcohol-exposed children (NC: n=23) when completing two tasks: a simple reaction time task (RT alone condition) and a reaction plus movement task (RT+Move condition). The movement involved responding to an imperative stimulus signal and depressing three target buttons in a set sequence. Participants completed 24 trials each for the RT alone and RT+Move response conditions. Results indicated no significant differences in performance among FAS, PEA, and NC groups during the RT alone condition. However, during the RT+Move condition, the FAS group produced significantly longer and more variable RTs than the PEA and NC groups, which produced comparable RTs. The FAS group also produced significantly slower movement times when moving to all three targets, whereas movement time variability did not significantly differ as a function of group. The observed results indicate children with FAS experience deficits in response programming and movement time production.
