Tautologies are a key concept in propositional logic, where a tautology is defined as a propositional formula that is true under any possible Boolean valuation of its propositional variables. [2] A key property of tautologies in propositional logic is that an effective method exists for testing whether a given formula is always satisfied (equiv ...
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
Not all tautologies of classical logic lift to Ł3 "as is". For example, the law of excluded middle, A ∨ ¬A, and the law of non-contradiction, ¬(A ∧ ¬A) are not tautologies in Ł3. However, using the operator I defined above, it is possible to state tautologies that are their analogues: A ∨ IA ∨ ¬A (law of excluded fourth)
Discrete trial training (DTT) is a technique used by practitioners of applied behavior analysis (ABA) that was developed by Ivar Lovaas at the University of California, Los Angeles (UCLA). DTT uses mass instruction and reinforcers that create clear contingencies to shape new skills.
The three-term contingency (also known as the ABC contingency) is a psychological model describing operant conditioning in three terms consisting of a behavior, its consequence, and the environmental context, as applied in contingency management. The three-term contingency was first defined by B. F. Skinner in the early 1950s. [1]
Contingency management (CM) is the application of the three-term contingency (or operant conditioning), which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
To the extent that contradictions are impossible, self-contradictory propositions are necessarily false as it is impossible for them to be true. The negation of a self-contradictory proposition is, therefore, supposed to be necessarily true. By contrast, a proposition that is contingently true is one in which its negation is not self-contradictory.
A behavioral cusp is any behavior change that brings an organism's behavior into contact with new contingencies that have far-reaching consequences. [1] A behavioral cusp is a special type of behavior change because it provides the learner with opportunities to access new reinforcers, new contingencies, new environments, new related behaviors (generativeness [2]) and competition with archaic ...
