Concept:Intra-individual differences refer to variations in different abilities or traits within the same person.
Explanation:The given child shows average intelligence, high achievement motivation, low creativity, and average social development.
These traits differ in level when compared with one another within the same child.
This means the child does not possess all abilities to the same extent.
Such differences among the abilities of a single individual are called intra-individual differences.
They exist in almost every person because no one is equally strong in all abilities.
In contrast, inter-individual differences are differences in abilities between two or more different individuals.
Measurable individual differences are those that can be assessed through standardized or non-standardized tests.
Observable individual differences are those that can be easily noticed, such as voice, communication skills, and appearance.
As all the traits mentioned belong to one child only, this is a clear example of intra-individual difference.
