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 ]
Spontaneous recovery: Spontaneous recovery is defined as the reappearance of a previously extinguished conditioned response after a rest period. That is, if the CS is tested at a later time (for example an hour or a day) after extinction it will again elicit a CR.
Extinction is considered successful when responding in the presence of an extinction stimulus (a red light or a teacher not giving a bad student attention, for instance) is zero. When a behavior reappears again after it has gone through extinction, it is called spontaneous recovery. It (extinction) is the result of challenging behavior(s) no ...
Being spontaneous can help to keep your brain healthy as you age too. ... Doing this in a structured way may make it easier to stick to, says Slingerland. For example, his 18-year-old daughter ...
Also observed is spontaneous recovery. That is, a habituated response to a stimulus recovers (increases in magnitude) when a significant amount of time (hours, days, weeks) passes between stimulus presentations. "Potentiation of habituation" is observed when tests of spontaneous recovery are given repeatedly.
Spontaneous remission, also called spontaneous healing or spontaneous regression, is an unexpected improvement or cure from a disease that usually progresses. These terms are commonly used for unexpected transient or final improvements in cancer .
Example: if a rat in a Skinner box gets food when it presses a lever, its rate of pressing will go up. Pressing the lever was positively reinforced. Pressing the lever was positively reinforced. Negative reinforcement (a.k.a. escape) occurs when a behavior (response) is followed by the removal of an aversive stimulus, thereby increasing the ...
Syncope ((syncope ⓘ), commonly known as fainting or passing out, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery. [1] It is caused by a decrease in blood flow to the brain, typically from low blood pressure. [1]
