Individual Difference during Aptitude
Aptitude is a specific capacity
that helps an individual to acquire a required degree of proficiency in a
specific field. Individuals differ from one another in their aptitudes. There
exist great variations among the individuals in relation to the area and extent
of aptitude. People are found to have different aptitude. Some have mechanical
aptitude, while the others have scholastic, musical or artistic aptitudes. Like
any other psychological trait, aptitude also seems to be distributed in the
population according to the principles of normal probability curve. That is, in
a random population, the aptitude in any specific field is normally distributed
with most people in the middle range of aptitude while only a few people make
very high or very low scores. An individual’s aptitudes are not all equally
strong. An individual may have good aptitude for one line of work and not for
certain others. These trait differences within an individuals and known as intra-individual
difference. The differences among individuals and within individuals are
fairly stable. Patterns of aptitudes do change to some extent, but a complete
reversal in aptitude within the life span of individuals is practically
unknown.
