Sigmund Freud

Sigmund Freud (1856-1939)
Freud believed that an individual's personality develops through a series of five stages.  These stages of development begin at birth and continue to shape human personality through adolescence.  These stages are oral, anal, phallic, latent, and genital.  If conflicts are not resolved in each of these stages, it can affect a child's adulthood.  Thus, Freud believed that an adult's psychological problems might actually stem from unresolved childhood conflicts.
 
 
Stage
Traits
Problems if not resolved
Oral (infants)
Children explore the world by placing objects in mouth--and obtain main source of pleasure through mouth
This can lead to nail-biting, overeating, etc.
Anal (1.5-2.5)
Children learn to control bodily functions--self control; anal-retentive traits
Anal-retentiveness leads to perfectionists
Anal-expulsiveness leads to messiness
Phallic (3)
Children discover pysical differences between sexes and become focused on their own bodies.
Children become attached to parent of other sex and competes with the parent of the same sex.  This can lead to anxiety and depression
Latency (5-6)
Conflict with parents; retreat from conflicts and repress all aggressive urges; impulses and emotions remain hidden
True Genital (puberty and on)
No new psychological conflicts--more aware of gender identity.
Conflicts unresoved from earlier stages resurface
