Differential emotions theory is a term in Izard's view that the major emotions are distinct at birth but emerge gradually in accord with maturation and the child's developing needs
Differential opportunity theory refers to a theory that attempts to join the concept of anomie and differential association by analyzing both legitimate and illegitimate opportunity structures available to individuals. Differential opportunity theory posits that illegitimate opportunities, like legitimate opportunities, are unequally distributed.
Differential reinforcement is defined as a procedure involving two (2) or more physically different behaviors: one behavior is reinforced, and all others are extinguished.
- Differential reinforcement of high rates (DRH) : Differential reinforcement of high rates (DRH) refers to a schedule in which reinforcement is contingent upon emitting at least a certain number of responses in a certain period of time - or, more generally, Reinforcement is provided for responding at a fast rate.
- Differential reinforcement of low rates (DRL) : Differential reinforcement of low rates (DRL) refers to a schedule in which a minimum amount of time must pass between each response before the reinforcer will be delivered - or, more generally, Reinforcement is provided for responding at a slow rate.
- Differential reinforcement of other behavior (DRO) : Differential reinforcement of other behavior (DRO) refers to reinforcement of any behavior other than a target behavior that is being extinguished. One variant of this is called Differential reinforcement of incompatible behavior (DRI), wherein the behavior which is being reinforced is specifically incompatible with the behavior being extinguished.
- Differential reinforcement of paced responding (DRP) : Differential reinforcement of paced responding (DRP) refers to a schedule in which reinforcement is contingent upon emitting a series of responses at a set rate - or, more generally, reinforcement is provided for responding neither too fast nor too slow.
Differential reinforcement of successive approximations refers to the procedure of reinforcing only some responses and not others. Differential reinforcement is used in the "shaping" of complex behaviors. (see Shaping.)
