  • Summary

    The role of appetitive needs in the etiology of addiction is described in this chapter, including consideration of typologies of needs, how appetitive need-satiation cycles may cross over into addiction, and factors that may facilitate dysregulation of appetitive effects. An overview of an Associational Memory-Appetitive System Relations Model (AMASR) is presented. The constituents of this model are described and include neurobiological vulnerability, lifestyle pushes (stresses) and pulls (seductions), associative learning of relations among addiction-related cues with subjective perception of appetitive needs fulfillment, and associative memory for alternative behaviors, all which interact and lead to addictive or nonaddictive behavior.
