Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning.In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. [1]
Imre Lakatos (UK: / ˈ l æ k ə t ɒ s /, [6] US: /-t oʊ s /; Hungarian: Lakatos Imre [ˈlɒkɒtoʃ ˈimrɛ]; 9 November 1922 – 2 February 1974) was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its "methodology of proofs and refutations" in its pre-axiomatic stages of development, and also for introducing the concept of the ...
Conditional release is a method of release from detention that is contingent upon obeying conditions under threat of return to detention under reduced due process protections. [ 1 ] When applicable in the context of post-conviction detention, unconditional release can be a synonym of parole .
The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
The rats, upon receipt of the first shock, displayed the expected unconditional responses to the shock (e.g., jumping, squealing, urinating, etc.), however with subsequent presentations of the tone-shock trials, those responses habituated somewhat. The largest change in behavior occurred during the time the tone was presented.
P(A|B) may or may not be equal to P(A), i.e., the unconditional probability or absolute probability of A. If P(A|B) = P(A), then events A and B are said to be independent: in such a case, knowledge about either event does not alter the likelihood of each other. P(A|B) (the conditional probability of A given B) typically differs from P(B|A).
