Wilhelm Wundt, the founding father of psychology:
Focused on the analysis of conscious experience into its elemental parts.
Modeled psychology after natural sciences.
Influenced by natural science approach to study the mind.
Behaviorism by John Watson:
Opposed Wundt’s focus on conscious experience.
Argued that psychology should study tangible aspects of human nature (observable behavior).
Only overt behavior is legitimate for psychology.
Sigmund Freud’s psychoanalysis:
Investigated the unconscious mind without the experimental method.
Developed theories based on clinical observations of patients.
*studied patients' behaviors, dreams, slips of the tongue, and free associations during therapy sessions. Instead of using controlled experiments, he interpreted these observations to infer the workings of the unconscious mind
In the late 1930s, through Gordon Allport's work, personality became systematized in American psychology.
Allport’s book "Personality: A Psychological Interpretation" marked the formal study of personality.
Personality theories reflect their authors' assumptions about humanity.
Are behaviors determined by forces beyond control, or can individuals choose their paths?
Are people destined for troubled lives, or can they grow into psychologically healthy beings?
Do past events dictate actions, or do future expectations drive behavior?
Are individuals aware of their actions and motivations, or influenced by unconscious forces?
Is personality shaped more by biology or social relationships (heredity vs. environment)?
Is individuality or shared characteristics more noticeable in humans?
