How we know our minds: The illusion of first-person knowledge of intentionality

As adults we believe that our knowledge of our own psychological states is substantially different from our knowledge of the psychological states of others: First-person knowledge comes directly from experience, but third-person knowledge involves inference. Developmental evidence suggests otherwise. Many 3-year-old children are consistently wrong in reporting some of their own immediately past psychological states and show similar difficulties reporting the psychological states of others. At about age 4 there is an important developmental shift to a representational model of the mind. This affects children's understanding of their own minds as well as the minds of others. Our sense that our perception of our own minds is direct may be analogous to many cases where expertise provides an illusion of direct perception. These empirical findings have important implications for debates about the foundations of cognitive science.

The psychology of folk psychology

Folk psychology, the naive understanding of mental state concepts, requires a model of how people ascribe mental states to themselves. Competent speakers associate a distinctive memory representation (a category representation, CR) with each mentalistic word in their lexicon. A decision to ascribe such a word to oneself depends on matching to the CR an instance representation (IR) of one's current state. As in visual object recognition, evidence about a CR's content includes the IRs that are or are not available to trigger a match. This poses serious problems for functionalism, the theory-of-mind approach to the meaning of mental terms. A simple functionalist model is inadequate because (1) the relational and subjunctive (what would have happened) information it requires concerning target states is not generally available and (2) it could lead to combinatorial explosion. A modified functionalist model can appeal to qualitative (phenomenological) properties, but the earlier problems still reappear. Qualitative properties are important for sensations, propositional attitudes, and their contents, providing a model that need not refer to functional (causal-relational) properties at all. The introspectionist character of the proposed model does not imply that ascribing mental states to oneself is infallible or complete; nor is the model refuted by empirical research on introspective reports. Empirical research on “theory of mind” does not support any strict version of functionalism but only an understanding of mentalistic words that may depend on phenomenological or experiential qualities.
