Rescorla Wagners Theory of Conditioning

• Associative Strength (V) is the sum of the
  strength of all cues present ( ?V)
• The US can support of fixed amount of
  conditioning (?)
• Change in Associative Strength (?) is based on
  difference between ?V and ?.

Applications of Rescorla-Wagner Theory

• Conditioned Inhibition
• N, NL- gt Light lt 0
• Blocking
• N, NL gt Light 0
• Contingency
• N, gt Context gt 0
• Protection from Extinction

Stimulus Combinations

• Simultaneous Associations
• The association of two stimuli that are
  experienced at the same time, like the
  association of the eyes and the nose of a face
• Successive Associations
• The association of two stimuli that are
  experienced in succession, like the sight of a
  person and the sound of the persons voice
