本研究的主要目的是检验使用节律信息来诱导时间预期是否可以克服额叶损伤患者在受控时间准备方面的缺陷(即时间定向和早期效应)。对15名额部病变患者和15名匹配的对照组受试者进行了两项任务：一项符号提示任务，其中关于目标出现时间的预测信息由符号提示(短线-早与长线-晚间隔)提供；另一项节奏提示任务，其中预测时间信息由节奏(快节奏-早与慢节奏-晚间隔)提供。符号线索任务的结果复制了右额叶患者的时间定向缺陷，以及我们先前研究(Trivino，Correa，Arnedo，&Lupianez，2010)中报道的右额叶和左额叶患者没有早期影响。然而，在节奏线索任务中，右额叶组表现出正常的时间定向和早期效应，而左额叶组则表现出明显的缺失。这些发现表明，由节律诱导的自动时间准备可以帮助额叶患者有效地利用隐含的时间信息在最佳时间做出反应。我们的神经心理学发现也为神经模型提供了一个新的建议，在该模型中，自动的颞叶准备是左侧的，而受控的颞叶准备是右侧的额叶。(C)2011爱思唯尔有限公司。保留所有权利。
The main aim of this study was to test whether the use of rhythmic information to induce temporal expectations can overcome the deficit in controlled temporal preparation shown by patients with frontal damage (i.e. temporal orienting and foreperiod effects). Two tasks were administered to a group of 15 patients with a frontal brain lesion and a group of 15 matched control subjects: a Symbolic Cued Task where the predictive information regarding the time of target appearance was provided by a symbolic cue (short line-early vs. long line-late interval) and a Rhythm Cued Task where the predictive temporal information was provided by a rhythm (fast rhythm-early vs. slow rhythm-late interval). The results of the Symbolic Cued Task replicated both the temporal orienting deficit in right frontal patients and the absence of foreperiod effects in both right and left frontal patients, reported in our previous study (Trivino, Correa, Arnedo, & Lupianez, 2010). However, in the Rhythm Cued Task, the right frontal group showed normal temporal orienting and foreperiod effects, while the left frontal group showed a significant deficit of both effects. These findings show that automatic temporal preparation, as induced by a rhythm, can help frontal patients to make effective use of implicit temporal information to respond at the optimum time. Our neuropsychological findings also provide a novel suggestion for a neural model, in which automatic temporal preparation is left-lateralized and controlled temporal preparation is right-lateralized in the frontal lobes.
