Research suggested the possibility that temporal cognition may be different in autistic spectrum disorder (ASD). Although there are some empirical studies examining timing ability in these individuals, to our knowledge, no one directly assessed the ability to predict when an event will occur. Here, we report a study on implicit temporal preparation in individuals with ASD as indexed by the variable foreperiod (FP) effect. We compared a group of adult ASD participants to a group of typically-developed (TD) controls, for their respective abilities to utilize implicit temporal information in a simple detection task with three different preparatory intervals (FP, short, middle and long). Participants were given a warning tone to signal an imminent stimulus, and asked to press a key as quickly as they could upon detection of the stimulus. Both groups were able to use implicit temporal information, as revealed by both the variable-FP effect (i.e., faster response for targets appearing after a long FP) and asymmetric sequential effects (i.e., slower response in short-FP trials following a previous long-FP trial). The TD group exhibited a faster response in a long-FP trial that was preceded by short-FP one, whereas the ASD group did not, as reflected in their higher percentage of response omissions for a target that appeared later than in the previous trial. The reduced ability of ASD participants to modulate their responses under these conditions might reflect a difficulty in time-based monitoring of stimulus occurrence.

自闭症谱系障碍成人的时间准备:可变的前期效应

研究表明,自闭症谱系障碍 (ASD) 的时间认知可能不同。尽管有一些实证研究检验了这些人的计时能力,但据我们所知,没有人直接评估预测事件何时发生的能力。在这里,我们报告了一项关于 ASD 个体内隐时间准备的研究,该研究由可变前期 (FP) 效应索引。我们将一组成人 ASD 参与者与一组典型开发 (TD) 对照进行比较,以了解他们各自在具有三个不同准备间隔(FP、短、中和长)的简单检测任务中利用隐式时间信息的能力。参与者被给予警告音以表示即将受到刺激,并要求他们在检测到刺激后尽快按下一个键。两组都能够使用隐含的时间信息,正如可变 FP 效应(即,在长 FP 后出现的目标的更快响应)和不对称顺序效应(即,在之前的长 FP 之后的短 FP 试验中响应较慢) -FP 试验)。TD 组在短 FP 之前的长 FP 试验中表现出更快的反应,而 ASD 组没有表现出更快的反应,这反映在他们对比上一次试验晚出现的目标的反应遗漏百分比更高。ASD 参与者在这些条件下调节反应的能力下降可能反映了基于时间的刺激发生监测的困难。长 FP 后出现的目标的响应更快)和不对称的顺序效应(即,在之前的长 FP 试验之后的短 FP 试验中反应较慢)。TD 组在短 FP 之前的长 FP 试验中表现出更快的反应,而 ASD 组没有表现出更快的反应,这反映在他们对比上一次试验晚出现的目标的反应遗漏百分比更高。ASD 参与者在这些条件下调节反应的能力下降可能反映了基于时间的刺激发生监测的困难。长 FP 后出现的目标的响应更快)和不对称的顺序效应(即,在之前的长 FP 试验之后的短 FP 试验中反应较慢)。TD 组在短 FP 之前的长 FP 试验中表现出更快的反应,而 ASD 组没有表现出更快的反应,这反映在他们对比上一次试验晚出现的目标的反应遗漏百分比更高。ASD 参与者在这些条件下调节反应的能力下降可能反映了基于时间的刺激发生监测的困难。这反映在他们对比上一次试验出现得晚的目标的反应遗漏百分比更高。ASD 参与者在这些条件下调节反应的能力下降可能反映了基于时间的刺激发生监测的困难。这反映在他们对比上一次试验出现得晚的目标的反应遗漏百分比更高。ASD 参与者在这些条件下调节反应的能力下降可能反映了基于时间的刺激发生监测的困难。
