Environment Effects
- These are developmental times (stages) sensitive to insult, be aware of these times, the causes and the potential effects.
Critical periods of development refer to times when genetic or materal effects can impact upon the developmental process. The timing of these effects will impact on different systems at different times.
Systems with long periods of development are more susceptible to developmental abnormalities. Which systems take a long time to develop?
The Fetal period is also potentially sensitive to maternal effects that impact upon interuterine growth. Along these lines there is growing evidence that low birth weight, and therefore inhibited fetal growth, may have postnatal effects on lifelong health outcomes. (More? Fetal Origins Hypothesis)
