ABSTRACT

Psycholinguistic measures in the context of foreign language (L2) learning research isolate the phenomenon of interest from irrelevant factors and thereby increase the likelihood of scientific observations. This article is a critical review of the issues concerning the construct validity of some of the traditional measures, focusing specifically on three measurement variables: response time, eye movement, and dysfluency. The advantages and liabilities of several task types are discussed in some detail. Furthermore, two widely recognized problems in assessing and validating constructs, construct misrepresentation and intervention of extraneous variance, are recapitulated. In conclusion, it is suggested that a single measure cannot provide strong evidence for the explanandum in L2 research, and thus the triangulation of methodological tools in both their applications and interpretations should be given priority over efforts to extend their individual validity.
