cue reactivity
Cue reactivity is a phenomenon of addiction found in numerous laboratory studies showing that people who are addicted to drugs have significant physiological and subjective reactions to presentations of drug-related stimuli.〔Carter & Tiffany 1999, p. 327–340〕 In investigations of these reactions, addicts are exposed to both drug-related cues (e.g., cigarettes, bottles of alcohol, drug paraphernalia) and drug-neutral cues (e.g., pencils, glasses of water, a set of car keys) while changes in craving self-report, physiological responses, and, less frequently, drug-use behaviors are monitored.
==Scientific findings==
A recent meta-analysis of over 40 cue-reactivity studies with people who smoke cigarettes, have an alcohol, heroin or cocaine addiction strongly supports the finding that people who have addictions have significant cue-specific reactions to drug-related stimuli. In general, these individuals, regardless of drug of abuse, report robust increases in craving and exhibit modest changes in autonomic responses, such as increases in heart rate and skin conductance and decreases in skin temperature, when exposed to drug-related versus neutral stimuli. Surprisingly, despite their obvious clinical relevance, drug use or drug-seeking behaviors are seldom measured in cue reactivity studies. However, when drug-use measures are used in cue reactivity studies the typical finding is a modest increase in drug-seeking or drug-use behavior.
