Abstract / Description of output

The relationship between heroin-related attentional bias (AB) and a proxy for dependence severity (monthly frequency of heroin use-injecting or inhaling) was measured in individuals attending a heroin harm reduction service. A flicker change blindness paradigm was employed in which change detection latencies were measured to either a heroin-related or to a neutral change made to a stimulus array containing an equal number of heroin-related and neutral words. Individuals given the heroin-related change to detect showed a positive relationship between heroin-related AB and the proxy for dependence severity; those given the neutral change showed a negative relationship. Both findings complement each other--and are consistent with the sending of more attention to heroin-related stimuli than neutral, the more severe is the dependence.
