Motivated Forgetting
Motivated
Forgetting is the idea
that people unknowingly revise
their history.

forgetting serve?
Motivated Forgetting
 Repression:
idea put forth
by psychoanalytic theorists
like Freud which states
anxiety arousing thoughts,
feelings, and memories can
be banished from
consciousness.
 Ex: child abuse, rape, incest
may be repressed and not be
able to be actively recalled.
Memory Construction
 Memory
Construction refers to the idea
that memories are NOT objective,
recordings of the actual events we
experience.
 Our memories are often affected by our
pre-existing schemas and involve
information filtering and interpretations.
