Two portraits of Spence.

Abstract

A response to H. H. Kendler's (2001) comments on D. B. Wiseman's (2000 original article about Kenneth Spence's human learning research is presented. Specifically addressed are distinctions between objectivity and subjectivity and Kendler's view about Spence. The current response also describes a contrast between Spence's (a) philosophical views about science as formally expressed to psychologists outside of the University of Iowa and (b) behavior when conducting his experimental research within the Iowa classical conditioning laboratory.
