Freud
Stages of Psychosexual Development
• Oral Stage (0-1 year)
• Anal Stage (1-3 years)
• Phallic Stage (3-5/6 years)
• Latency Period (5/6 – puberty)
• Genital Stage (puberty – maturity)
The events of psychosexual development may lead to
fixations later on in adult life

must be met
before higher
ones

Erikson
• Focused on child development
• Concerned with identity crises
• Contributed eight stages of life
– Each stage offers a crisis that must be resolved
– Success at later stages depends on ability to resolve
earlier crises
• Overcoming crises successfully leads to healthy personality
development
• Inability to resolve crises can lead to unhealthy development
• Personality develops through lifetime
– Expands on Freud’s infancy theories
– Extends development to late adulthood
Adler
• motivating force is sense of
inferiority
– People strive for perfection
• People try to overcome with
compensation
– Striving towards perfection or
superiority
• Compensation can be too great
(overcompensation – superiority
complex)

Gilligan

– Almost exclusively researched males
• Found different moral perspectives among genders
– Male – Justice orientation – rights, principles, rules, …
– Female – Care orientation – concern, sensitivity, …
• Preconventional stage – individual survival
– Transition from selfishness to responsibility for others
• Conventional Stage – self sacrifice
– Transition from goodness to truth
• Postconventional - nonviolence
Marx
• Motivation by economic conditions
– Economic conditions affect other social structures
(religion, politics, art,…)
• Wrote Communist Manifesto
– Outlined struggle in which proletariat is exploited by
bourgeoisie – class struggle
– Proletariat sells labour to owner, who enjoy surplus
value
• Proletariat – large group of working class
• Bourgeoisie – small group of owners
• Suggested revolution by working class and
ultimately a classless society
Durkheim
• Emphasis on social structure
– Society (exterior to individual) can explain social
behavior
• Social stability found in common religion and
morality
– Loss leads to confusion (Anomie)
• Explained suicide as result of anomie, over
association, or under association
– Strong social ties tend to reduce likelihood of suicide
– Excessive social ties can increase the likelihood of
suicide
Weber
• Reaction to Marx
– Motivation not by economic condition but meaning
(religion)
• Examined relationship between religion and
economy
– Found capitalism thrives under western religions (but
not eastern) – Protestant work ethic
• Study of social structures alone cannot explain
human behavior
– Study of Sociology must be a mix of interpretation
and experience
