Contributions to child psychology:

This revision of the Binet-Simon scale has become a more efficient way of studying child intelligence because it is broken down into different subtests which the examinees must complete in order to recieve an overall IQ score opposed to a mental age score. (Boake, 2002) The test progresses by the abilities of the examinees so that they may complete tasks according to their level of intelligence. This system was developed so that individuals taking the test would not feel frustrated on questions which were too difficult as well as not bored with questions which were too simple. As more and more revisions have been made to this test over the years, the scoring system has gone from being based on an age scale to being based on a point scale. (Becker, 2003) Click here to see the progression of these revisions in Table 1. The many revisions of this test has led to a decrease in it’s limitations and an increase in it’s advantages. (Becker, 2003) This progression is evident when looking at Table 6.
