Abstract
The contemporary revival of [human] interactional psychology has focused upon disposition and situation as interacting processes and as determinants of responses. These analyses are extended to phenomena which involve complex patterns of behavior over time, drawing upon examples from the literature on alcoholism. The consistency-situation specificity issue is reviewed in this context. Within a fully reciprocal, temporally extended model, personality and environment are conceived as mutually interactive and as influenced by patterns of behavior. Various models are reviewed in which personality and environment are joint determinants of behavior.
