ABSTRACT
Character is admittedly acquired, although its foundation must be considered as laid in the structure and constitution which the individual inherits at birth. The term personality is a convenient one in which to include those elusive factors which mark out one individual from another. The individual may drop off and add on sets of sentiments, may modify his impulsive behaviour in this or that respect, but the residuum which is peculiar to his personality remains constant. The teacher feels that individual differences are largely responsible for the serious breaches of discipline which from time to time occur. The researches of Ach with whom the term 'cautious' originated were conducted on the basis of certain characteristics which are clearly relevant to the teacher's task of understanding and allowing for individual differences. Emphasis has been laid chiefly upon those individual differences in emotional equipment which are most likely to lead to serious disturbance in the classroom and in life outside.
