Evan small variations in the nature of the us can produce changes in the nature of the cr: stimulus substitution model: The association of a cs with a us turns the conditioned stimulus into a surrogate us. Thus, the cs is assumed to activate neural circuits previously activated only by the us and elicit responses similar to those elicited by the us. In many situations, the biologically important consequence of pavlovian conditioning is not a change in responding to the cs but a change in how the organism responds to the us. The cs as a determining factor for the cr. As the cs rat was repeatedly paired with food, it came to elicit social affiliative responses. (orientation, approach, sniffing, and social contacts) The cs-us interval as a determining factor for the.
