Definition

The term sensitive period refers to the notion that the effects of environmental stimuli on the developing organism are stronger during certain periods of development. The traditional term, “critical period,” was based on the assumption that these developmental periods were innate and had a fixed onset and termination. However, more recent research has suggested that they are influenced by environmental factors and are flexible in terms of their beginning and end; thus, the term “sensitive periods” is more commonly preferred (Michel & Taylor, 2005).

Additional distinctions have been made between the terms “sensitive” and “critical” period. Fox (1970) suggested that the term “critical period” be used when a specific environmental stimulus is needed to cue normal development, whereas the term “sensitive period” be used to describe when the development is more easily influenced by a negative environmental event. The relative vulnerability of the...
