Abstract

Satiation, the processes leading to termination of a meal, and satiety, the state of inhibition over eating after ameal, both arise through the integration of cognitive, sensory and post-ingestive signals arising from consumption of foodsand drinks. Although signals arising from nutrient ingestion are important, especially for satiety, both satiation and satiety areinfluenced by more cognitive aspects of the consumer experience. Recent research in particular highlights the importanceof expectations about the likely effects of consumption and memories of effects of related products as elements of bothsatiation and satiety. This brief review assesses some of these psychological influences and discusses their implications foreffective product development.
