Maraun's (1998) 'mischaracterization of measurement' critique of const
ruct validity theory is examined in terms of the distinctions between:
(a) semantic denotation and a variable's being exemplified by a value
; (b) semantic denotation and theoretical implication; (c) the meaning
of a psychological concept and the theoretical properties of the ment
al structure or phenomenon denoted by the concept; and (d) using a psy
chological concept in everyday communication and investigating the phe
nomenon or structure denoted by the concept. The propriety of criticiz
ing psychological measurements on the basis of Wittgenstein's grammar
of psychological concepts is also discussed.
