Theoretical Background
Interpretations of why people with a substance addiction show more reactivity to drug-related stimuli have historically been derived from the framework of classical conditioning. During an individual's history of drug use, certain stimuli, such as environmental contexts or drug paraphernalia, reliably accompany drug administration. It is assumed that these stimuli, by virtue of their pairing with the unconditioned drug stimulus, become conditioned stimuli capable of eliciting conditioned responses in the form of reactions such as increased craving and heart rate. Presumably, these cue-specific reactions reflect motivational processes responsible for continuing drug use as well as relapse for people with an addiction attempting to remain abstinent.

Famous quotes containing the words theoretical and/or background:
“Post-structuralism is among other things a kind of theoretical hangover from the failed uprising of ‘68Ma way of keeping the revolution warm at the level of language, blending the euphoric libertarianism of that moment with the stoical melancholia of its aftermath.”
—Terry Eagleton (b. 1943)
“Silence is the universal refuge, the sequel to all dull discourses and all foolish acts, a balm to our every chagrin, as welcome after satiety as after disappointment; that background which the painter may not daub, be he master or bungler, and which, however awkward a figure we may have made in the foreground, remains ever our inviolable asylum, where no indignity can assail, no personality can disturb us.”
—Henry David Thoreau (1817–1862)
