Two Approaches to Personality: the same.
Idiographic versus Nomothetic Approach
The idiographic (person-centered) approach:
A focus on one individual at a time, and it tries to understand this individuals’ actions from the individuals’ characteristics.
The nomothetic (variable-centered) approach
A focus on the relation between a certain outcome such as academic achievement (getting an A in this class) to a variable like organized-disorganized.
Idiographic Nomothetic the same.
Traditional ModernGrand Theories Small TheoriesOne individual at a time Large samplesQualitative QuantitativeFreud Eysenck Idiographic question: Why did Mariah Carey have a nervous breakdown?
Nomothetic question: Are young stars in the music industry more likely to suffer a nervous breakdown than normal people?
Warning theories with case studies.
If you want to learn more about psychodynamic theories (Freud, Adler, Jung), DO NOT take PSY230
However, I hope to convince you in the rest of today’s lecture that the nomothetic approach examines interesting questions and provides answers that are relevant to the understanding of yourself and others.
