Sensory Deprivation Experiments Have Yielded All of the Following Insights

Sensory deprivation experiments have yielded all of the following insights into the development of our sensory systems, except.

A) when and with severity a sensitive period for a stimulus occurs during development is not uniform across all types of stimuli
B) deprivation of stimulus during the sensitive period of development always results in irreversible deficits
C) experience-dependent neural plasticity is most effectively accomplished during a sensitive period of development
D) a lack of early pattern vision can result in permanent visual deficits
