The objective of this study is to characterize development of certain physiological variables in infants (low and high risk for serious mental illness, i.e., schizophrenia).
We are collecting data on the development of several psychophysiological variables in infants will little to no genetic risk for schizophrenia, those with a parent with the disease, and infants prenatally exposed to nicotine. Currently, we are collecting evoked potentials to pairs of auditory clicks (p50) and to tones presented at varying intervals (MMN). We are also gathering information on infants’ abilities to detect patterns in the presentation of visual images using eye movements. Most of these studies are conducted with infants from 2 to 6 months of age.
