B. Concepts and Principles
Feature stimulus class
A group of stimuli that share an infinite number of possible relations and evoke the same response.
Fixed interval (FI) scallop
A pattern of responding specific to the fixed interval schedule of reinforcement, when the rate of responding decreases after the delivery of reinforcement, but gradually increases and speeds up at
Fixed interval schedule (FI)
A basic schedule of intermittent reinforcement in which a fixed amount of time must elapse before a single correct response produces reinforcement.
Fixed ratio schedule (FR)
A basic schedule of intermittent reinforcement in which a fixed number of correct responses must be emitted for reinforcement to be delivered.
Formal similarity

Free-operant avoidance
When the contingency for behavior is that it prevents and/or delays the onset of an aversive stimulus. The avoidant response occurs without the presence of a signal/SD and can occur
Function-altering effect
A phenomenon where the consequence of a behavior in the presence of an MO changes the behavior evoked by the specific or similar MOs in the future.

Functional stimulus class
A group of stimuli that share a common effect (i.e., function) on a behavior.
Generalization
When a behavior occurs in conditions that differ from the original teaching conditions (e.g., across other settings, behaviors, stimuli, and people).
