Young-Helmholtz
Three types of color receptors(cones)
Red, Blue or Green
Hering’s Opponent-Process Theory
Three types of bipolar receptors: Red/Green Yellow/Blue White/Black Negative After Images support this theory
Color blindness
Due to sex linked recessive trait - males at higher risk
Weber’s law
The more intense the stimulus, the greater the increase in intensity needed to produce just noticeable difference
Fechner’s Law
Physical stimulus changes are logarithmically related to their psychological sensations
H.M

Temporal Lobes
Storage & retrieval of long term declarative memories

Basal Ganglia,
Motor cortex & Cerebellum
Procedural & Implicit memory
Long Term Potentiation
Hippocampus
James-Lange theory

Cannon-Bard theory
Emotion provoking stimuli simultaneously produce emotional experience
Papez Circuit
Mediates experience and expression of emotion.
