Protocol Number:
04-CH-0250
- Title:
Event Related Potentials in Infants and Adults
- Number:
04-CH-0250
- Summary:
This study will explore the development of visual perception and the brain activity that underlies it. It will examine electrical activity in the brain while people are processing characteristics of the visual environment, and how that processing might change with development.
Infants who are within 2 weeks on either side of their 4-month birthday may be eligible for this study. A parent of the child also participates.
Parents who join the study are asked basic questions about their family, such as its size and ethnic make-up, their infant's birth date, complications of pregnancy or delivery, and any health problems of the infant, such as congenital developmental disorders or visual abnormalities.
Each family is seen at the clinic one time for a 45-minute visit. The infant is outfitted with an elastic net containing many small sensors that make contact with the scalp. He or she is then shown pictures on a computer screen. The sensors in the head net are connected to a computer that records the infant's brain activity while the infant watches the pictures on the screen. The head net is moistened with warm water before being applied, and is not uncomfortable to wear. Towels are available throughout the session to dry any excess moisture from the net.

INCLUSION CRITERIA:
Participants will be selected for inclusion in this study and each to follow on the basis of age, gestational status (i.e., full-term vs. pre-term birth), visual normality, and general health status. Once the recruitment letters have been mailed, a brief screening interview will be conducted with all parents who call to express an interest in participating. These parents will be asked about their infants' birth date, expected due date, and any diagnoses of severe perinatal complications, visual abnormalities, and congenital developmental disorders. The initial group will be recruited to participate within two weeks on either side of their 4-month birthday. Infants with a gestational age of less than 36 weeks, and/or those with histories of severe perinatal complications, visual abnormalities, or congenital developmental disorders, or a family history of color-vision deficiency will not be recruited for participation. Equal numbers of males and females will be recruited to participate.
