The approach taken by the specialist in personality assessment is based on the assumption that much of the observable variability in behaviour from one person to another results from differences in the extent to which individuals possess particular underlying personal characteristics (traits). The assessment specialist seeks to define these traits, to measure them objectively, and to relate them to socially significant aspects of behaviour. Personality
The concept of personality has different meanings in different context and within psychology it has been defined in many different ways. It is a broad, integrating concept and the definition of personality is restricted to properties which are both stable and distinctive. According to trait theorists personality can be defined as more or less stable, internal factors that make one person’s behaviour consistent from one time to another whereas according to proponents of social learning theories personality is viewed as dynamic responding to environment and people around them. | |
Nomothetic Approach to Personality Assessment
Psychologists adopting nomothetic approach to personality assessment believe that personality is primarily determined by heredity, genetics and biochemistry of our brains. They argue that personality is stable, consistent and that environmental factors and social influences have little effect. They believe that traits are source of human personality which makes individual behaviour stable over lifespan. Idiographic Approach to Personality Assessment
Psychologists adopting idiographic approach to study of personality consider measurement of traits as inappropriate because one person’s responses may not be comparable to another’s. They regard individuals as responding to environment and people around them and see the dynamics of the interactions as playing a critical part in shaping personality.
