No similar or
comparable treatment of the generic nature of
the stimulus (see Skinner, 1935, 1938) is to be
found in Chapter 9, which provides only a
very brief and inadequate discussion of wavelength
and intensity of light as "stimulus dimensions".
All other sensory modalities are
ignored. Directly relevant and basic questions
about measurement and the problem of quantitative
laws or functional relationships in the
analysis of behavior are nowhere to be found
(see Crozier, 1929; Hull, 1943; Skinner, 1938;
Woodrow, 1942; Galanter, 1966; etc.).
