Inhibition of return (IOR) refers to the slowing of responses to stimuli presented at the same location as a preceding cue. However, the cue-target paradigm used in most previous studies may have overestimated the contribution of eye movement programming to IOR, due to the existence of manual response inhibition effects. This confound can be circumvented by using a target-target paradigm in which participants respond to all stimuli. Here, we compared IOR magnitude from tactile cue-target and target-target tasks involving identical interstimulus intervals of 1,400 and 1,800 ms. Reaction times were measured using a foot pedal toe-lift response and a vocal response. Tactile IOR was observed using both modes of response, demonstrating IOR for the first time using a non-spatial, vocal response. Moreover, IOR effects were significantly smaller in target-target compared to cue-target conditions, thereby confirming the existence of the response inhibition confound.
返回抑制（IOR）是指对出现在与先前线索相同位置的刺激的反应速度减慢。然而，由于手动反应抑制效应的存在，大多数先前研究中使用的线索-目标范式可能高估了眼动编程对IOR的贡献。通过使用参与者对所有刺激做出反应的目标-目标范式，可以避免这种混淆。在这里，我们比较了触觉线索-目标任务和目标-目标任务中的IOR大小，这两个任务的刺激间隔均为1400毫秒和1800毫秒。使用脚踏板脚趾抬起反应和发声反应来测量反应时间。通过两种反应模式都观察到了触觉IOR，这首次证明了使用非空间发声反应时的IOR。此外，与线索-目标条件相比，目标-目标条件下的IOR效应显著更小，从而证实了反应抑制混淆的存在。
