Inner speech emerges in early childhood, in parallel with the maturation of the dorsal language stream. To date, the developmental relations between these two processes have not been examined. We review evidence that the dorsal language stream has a role in supporting the psychological phenomenon of inner speech, before considering paediatric studies of the dorsal stream’s anatomical development and evidence for its emerging functional roles. We examine possible causal accounts of the relations between these two developmental processes, and consider their (...) implications for phylogenetic theories about the evolution of inner speech and the accounts of the ontogenetic relations between language and cognition.

In this paper we address the question of what determines the content of our conscious episodes of thinking, considering recent claims that phenomenal character individuates thought contents. We present one prominent way for defenders of phenomenal intentionality to develop that view and then examine ‘sensory inner speech views’, which provide an alternative way of accounting for thought-content determinacy. We argue that such views fare well with inner speech thinking but have problems accounting for unsymbolized thinking. Within this dialectic, we present (...) an account of the nature of unsymbolized thinking that accords with and can be seen as a continuation of the activity of inner speech, while offering a way of explaining thought-content determinacy in terms of linguistic structures and representations.

Using the method of Descriptive Experience Sampling, some subjects report experiences of thinking that do not involve words or any other symbols [Hurlburt, R. T., and C. L. Heavey. 2006. Exploring Inner Experience. Amsterdam: John Benjamins; Hurlburt, R. T., and S. A. Akhter. 2008. “Unsymbolized Thinking.” Consciousness and Cognition 17 : 1364–1374]. Even though the possibility of this unsymbolized thinking has consequences for the debate on the phenomenological status of cognitive states, the phenomenon is still insufficiently examined. This paper analyzes (...) the main properties of unsymbolized thinking and advances an explanation of its origin. According to our analysis, unsymbolized thoughts appear as propositional states, that is, they are experienced as compositional conceptual phenomena, with semantic and syntactic features analogous to those of the contents of utterances. Based on this characterization, we hypothesize that UT is continuous with the activity of inner speech, in particular, it i... (shrink)
