Abstract
Tests AH 2 and AH 3 are group tests of reasoning with several features usually associated with individual tests of intelligence. In particular, they yield a three‐point profile in addition to their total or general score, and their range of relevance extends from 10‐year‐olds to intelligent young adults. They have a certain flexibility in that they can be administered with either a long or a short time‐limit, norms having been established on both sets of times. New techniques have been used in devising items and building‐in checks to ensure that there is one and only one defensible answer for each question.In the course of standardizing the two tests, several widely accepted findings have been confirmed, notably male superiority on Numerical, female superiority on Verbal and the greater variance found generally among males than females. Two further results are, however, worth noting: (a) the data do not support the suggestion, often made by teachers and other educationists, that girls tend to excel boys around 10–12 years of age owing to their earlier physical and mental maturation ‐ to be rejoined, or surpassed, by the boys in their early teens; (b) it seems well worth while incorporating pictorial items in a group test of reasoning, intended to cover a wide age range. This type of item enables the younger (and the less able) to show their strength in an area usually neglected in group tests and it proves to be a task in which they delight.
