In this paper an account of the semantics of psychological ascription
in terms of sentential modeling is articulated and defended. It is sug
gested that psychological ascriptions, both lay and scientific, are th
eoretical descriptions, but denied that the semantics of psychological
descriptions are determined by the causal explanatory propositions re
lating observable stimuli, psychological states and observable behavio
r in which they regularly figure-the 'theory-theory' account of the se
mantics of psychological ascription favored by most contemporary psych
ologists and philosophers. It is argued that the recognition of the al
ternative account of the semantics of psychological ascription in term
s of sentential modeling enables one to take a less 'theory-theory'-in
formed look at the implications of recent research on 'self-perception
' and the 'child's theory of mind'.
