Limits to Adaptation

Abstract

The mechanisms of adaptation and coping are considered in detail in this chapter. Firstly, how can stimuli vary in time, intensity and modality? The links between the nature of stimuli and the responses that can result are illustrated diagrammatically. Habituation and sensitisation are defined and variation in patterns of adaptation discussed. Some of the disorders that result from difficulties in regulation and their relationships with welfare are considered. When can adaptation problems be tolerated, when do they cause poor welfare and when do coping mechanisms fail so that the impact becomes lethal?
