Compare the approaches of Cattell and Binet to the development of mental tests.
In an article being published in 1890, Cattell made use of the term tests which were mental, and while being at the University of Pennsylvania he carried out a course of similar tests for his students.
Cattell documented, psychology could not get the exactness and certainty of the sciences which were physical until it lingers on a framework of measurement and experiment. A step taken towards this approach can be done by applying a course of tests which are mental and measurements to many numbers of individuals.
This is accurately what Cattell wanted to do. He maintained the testing research at Columbia and gathered data and information from many classes of prospective students.
The types of tests he used in attempting to examine the range and variation of capacities of humans varied from the cognitive abilities and intelligence tests psychologists established later, which would make use of more complicated tasks which were mental.
Tests by Cattell, like that of Galton, dealt chiefly with basic measurements of sensorimotor, comprising pressure of dynamometer, rate of action, two-point threshold sensitivity of skin, pressure required on the forehead for causing pain, only differences in examining weights, time of reaction for sound, and needed for naming of the colors.
