Fernyhough (2004) proposed that inner speech should take two distinct forms: expanded inner speech, in which internal dialogue retains many of the phonological properties and turn-taking qualities of external dialogue, and condensed inner speech, in which the semantic and syntactic transformations that accompany internalization are taken to their conclusion, and inner speech approaches the state of “thinking in pure meanings” described by Vygotsky (1934/1987).

I'm interested in whether "thinking in pure meanings" is associated with felicity at any cognitive tasks; especially whether STM, as opposed to activated LTM, is more closely tied to condensed speech.
There is the so called "tip of the tongue phenomena", when we cannot quite recall a familiar word. If this is a very significant psychological phenomena, one which gets right to the heart of 'memory', maybe condensed inner speech is less relevant when LTM is called upon, either in recall or in order to store information in the short term, than is the norm for STM
