PSYCHOLOGICAL THEORIES of DREAMING
Theory 1: FREUD'S PSYCHOANALYTIC APPROACH
A01: Dreams provide a 'royal road' to the unconscious mind.
A02: Physiological evidence:
PET scans, show that during REM sleep, the rational part of the brain (prefrontal cortex) is inactive whereas forebrain centres concerned with memory and motivation (irrational part) are active.
A01: Primary-process thought
Unacceptable id thoughts are repressed into the unconscious, but must be released through dreams.
A02: Cognitive evidence:
Neural networks (HOPFIELD et al., 1983) deal with overload by condensing 'memories', which supports FREUD's view of dreaming as condensation.
