The literature on rigidity reveals a concentration in two fairly distinct areas: that of problem solving for cognitive rigidity) and motor rigidity. The early investigators felt that assessing these peripheral response mechanism would give a measure of the deeper, central personality mechanism that affects all of behavior. However, such an assumption was highly questionable and based more on analogical reasoning than on empirical evidence. It was Cattel who first pointed out that assuming motor rigidity "extends also through all dissappontement to feel or think perseveratively is a speculation undertaken at one's own risk" (1946, p. 233). Luchins (1951), concerned with problem solving rigidity, has also expressed doubt that cognitive measures of rigidity tap central personality rigidity.
