, for Vygotsky, exists only in its distinction from speech for others; it relies on--indeed originates with--a child's ability to distinguish between a shorthand speech for oneself and publicly comprehensible speech.
With the aid of advanced scanning techniques, neurologists have pinned down the location of inner speech
to the brain's left inferior frontal region.
The term "thought" can encourage us to see mental life mainly in terms of inner speech
. The obvious alternative, "consciousness," is better because it accommodates immediate states such as emotions, but it can have the implication of self-consciousness, which I want to avoid.
"By providing a way to directly and precisely measure the effect of inner speech
on the brain, this research opens the door to understanding how inner speech
might be different in people with psychotic illnesses such as schizophrenia," says Associate Professor Whitford.
Children with autism often miss out on the early communicative exchanges when they are young which may explain their tendency not to use inner speech
when they are older.
In the study, those individuals with more profound communication impairments also struggled most with the use of inner speech
for complex tasks.
In inner speech
words die as they bring forth thought.
One example is research about inner speech
(defined as speech without external vocalization), which is required during execution of different psycholinguistic tasks, such as the ones involving phonological memory, silent reading, and linguistic judgments.
Vygotsky argued that originally children use speech for social reasons only, but eventually they internalize it as well, and this new development of inner speech
makes their thought processes a great deal more efficient and more abstract than they were before.
A group of 426 native Spanish-speaking college students of English as a Second Language (ESL) was surveyed on its use of mental rehearsal or inner speech
, and 9 subjects identified as consistently using mental rehearsal were interviewed in greater depth.
In some ways, this view of thinking (as verbal thought or inner speech
) does not sit well with the internalist perspective that Palmer describes.
"Experimental methods are allowing us to investigate people's inner speech
, of both the explicit and implicit variety, and how what they say to themselves shapes the course of their behaviours."
