If, for some reason, the organism does not receive the appropriate stimulus during this "critical period" to learn a given skill ...

    Some of the most pervading examples of this can be seen through the development of the visual cortex in addition to the acquisition of language as a result of developmental plasticity during the critical period. [8] [32] A lesser known example, however, remains the critical development of respiratory control during developmental periods. At ...

    A simple example of interaction involves plants: Some plants grow toward the light (phototropism) and some away from gravity (gravitropism). Many forms of developmental learning have a critical period, for instance, for imprinting among geese and language acquisition among humans. In such cases, genes determine the timing of the environmental ...
