Abstract

Inner speech has been found to be supportive in executive control functions in a variety of executive tasks. In this study, the role of inner speech in executive control is explored with a goal neglect version of the go/no-go task. A systematic series of 4 experiments examined whether inner speech is spontaneously implicated in the performance of this task and, if so, how. In Experiments 1-3, using a go/no-go task, articulatory suppression effects were found within no-go trials only despite frequency manipulations and changing the mappings to the responses. In Experiments 4 and 5, the stopping component of the task was removed. The effects of articulatory suppression completely disappeared, suggesting that inner speech might specifically help stop a response, rather than overcome a frequency bias per se.
