The studies in INVISION Lab are conducted by Professor James L. Dannemiller and his technical staff, as well as graduate students and postdoctoral fellows.

To conduct our studies, we rely on the help of the babies and their parents who volunteer their time to participate.
Our procedure is a very simple one. Your infant will be comfortably sitting in an infant seat in front of a computer monitor for a brief period of time (approximately 15 minutes) and various patterns will be presented on the screen. The patterns will vary depending on the particular study, but typically they imply different contrast, colors and/or movement. You will stay with your infant throughout your entire visit, which will be the only one you pay to our lab.

A video camera, located above the monitor, records the infant’s eye movements as he/she looks at the patterns. We will observe your infant’s eye movements and we will measure how much time does he/she spend with each pattern. Like adults, babies look longer at things they find new or surprising. We are interested in when and how fast the baby makes an eye movement in relation to the time of the presentation of a pattern; these eye movements tell us what type of visual information infants are interested in and how they analyze this information. It is also an indication of how visual development takes place.

Most infants find this kind of experiment very interesting, nonetheless it is up to them to look at the patterns or not. If at any time or any point the infant becomes sleepy or hungry or starts crying we stop the study. Your baby’s happiness and comfort is the most important aspect of the experiment.

If you are interested in having your infant participating in our study, please fill in the form and we will contact you.
