这项双任务研究考察了内部言语在任务切换中的作用。实验一证明，通过发音抑制来扰乱内部言语会显着增加转换成本。随后的三个实验试图通过引入额外的操作（即实验 2 中的线索类型、实验 3 中的任务难度以及实验 4 中的任务切换数量）来明确内部言语在任务切换中的作用，然后检查这些因素是否调节了发音抑制对切换成本的影响程度。只有暗示类型的操纵——假设会影响参与者依赖言语自我指令的程度——调节发音抑制效应，这表明内部言语通过检索和激活即将到来的任务的语音表示来充当内部自我暗示装置。 (C) 2002 年爱思唯尔科学（美国）。版权所有。
This dual-task study examined the role of inner speech in task switching. Experiment I demonstrated that disrupting inner speech via articulatory suppression dramatically increases switch costs. The three subsequent experiments attempted to specify the role of inner speech in task switching by introducing additional manipulations (i.e., types of cues in Experiment 2, task difficulty in Experiment 3, and the number of tasks switched between in Experiment 4) and then examining whether these factors modulated the magnitude of the articulatory suppression effect on switch costs. Only the cue type manipulation-hypothesized to affect the degree to which participants rely on verbal self-instruction-modulated the articulatory suppression effect, suggesting that inner speech serves as an internal self-cuing device by retrieving and activating a phonological representation of the upcoming task.
