Author(s): Nedergaard, Johanne; Lupyan, Gary | Abstract: It is commonly assumed that inner speech – the experience of thought as occurring in a natural language – is both universal and ubiquitous. Recent evidence, however, suggests that similar to other phenomenal experiences like visual imagery, the experience of inner speech varies between people, ranging from constant to non-existent. We propose a name for a lack of the experience of inner speech – anendophasia – and report four studies examining some of its behavioral consequences. We found that people who report low levels of inner speech have lower performance on a verbal working memory task and have more difficulty performing rhyme judgments based on images. Task switching performance, previously linked to endogenous verbal cueing, was unaffected by differences in inner speech. Studies of anendophasia, together with aphantasia, synesthesia, and differences in autobiographical memory are providing glimpses into what may be a large space of hitherto unexplored differences in people’s phenomenal experience.
  • Inner speech is considered universal and ubiquitous, but its perception varies from person to person.
  • Lack of inner speech experience is called anendophasia.
  • Individuals with low levels of internal speech perform worse with verbal working memory and image-based rhyming judgments.
  • Differences in internal speech do not affect the efficiency of task switching.
  • Research on anendophasia adds to the diversity of phenomenal human experience.

    Fascinating stuff. I love that we’re learning more about the variations in how we experience thoughts and the world itself.

        Mine either only runs some of the time or it’s all the time and I’m too distracted with more abstract thought to notice. I’m not sure which.

            I do my best thinking when a song is playing in my head. Might be an ADHD thing. Need to occupy some mental processes so I don’t get distracted.

            Do you hear Thom’s voice in your head?

    Never heard of that before but I usually don’t have a voice inside my head talking to me unless I consciously do it. Usually I use my “internal audio” to play music while I’m doing stuff. Then again, my internal monologue is often external anyways.
