Abstract:
Pigeons were trained in two experiments with negative patterning discriminations that were accompanied by an irrelevant cue. For Experiment 1, the discriminations were of the form AX+ BX+ ABX-, where A and B were relevant, X was irrelevant, and + or - indicate whether or not reinforcement was delivered. The discriminations for Experiment 2 were of the form A+ B+ AX+ BX+ ABX-. A subsequent test phase in both experiments revealed that the associability of A and B, and hence the attention paid to these stimuli, was less than the associability of X. The results are explained with a modified version of a configural theory of associative learning.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
Punishment
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior.

Instinctive Drift
Reinforcement
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:
