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 ...

One critical period is weeks 8-24 of gestation. Another sensitive period shortly after birth may exist with a peak in testosterone in male infants during postnatal months 1-5. [14] Auyeung et al. tested for an association between fetal and postnatal testosterone and autism in children. The results supported the idea that there is a critical ...
In psychology and ethology, imprinting is any kind of phase-sensitive learning (learning occurring at a particular age or a particular life stage) that is rapid and apparently independent of the consequences of behaviour. It was first used to describe situations in which an animal or person learns the characteristics of some stimulus, which is ...
Shamsud-Din Jabbar used a rare explosive in New Orleans that has never before been used in a U.S. or European terrorist attack. A key question is how he learned of the explosive and managed to ...
