Studies aimed at learning more about speech behavior, maternal sensitivity, or learning behavior in infancy are often carried out using The Observer® XT. The reaction to certain stimuli is captured on video. In infancy you can observe an explosive growth. Therefore, a lot of researchers choose to focus on this age group. Research is often performed in observation labs. In such a controlled environment you can accurately measure for instance exploratory gaze behavior. Some researcher use eye tracker data together with video to capture the exact gaze of the infant. Interested in managing and recording video/audio in multiple rooms?

Exploring early life developments
Many of our habits that we never think about questioning develop in infancy. For instance, handedness develops at a young age and the preference for using one hand over the other usually stays with us for a lifetime. However, infants are not able to communicate effectively and so observation studies are the best way to learn more about these early life developments. The Observer XT codes the behaviors of young children efficiently and accurately and is the ideal tool to use to explore the early life developments of an infant.

The HANDS lab and the Infant Development Center
The HANDS lab at Florida International University, Miami and the Infant Development Center of the University of North Carolina at Greensboro work together to study the development of hand use in infants. Infants explore much of their world with their hands. By studying how the hands are controlled, they learn new things about development. In a recent study, Eliza Nelson and colleagues took a particular interest in asymmetric bimanual actions. An observation lab is the ideal environment to record this behavior in great detail. They focused on actions where two hands work together to achieve a goal, a skill known as Role-Differentiated Bimanual Manipulation. The researchers set up experiments in their laboratory, the Infant Development Center (IDC). In the experiment, the passive hand stabilized or held the item for the active hand to perform the action. Test sessions were recorded with two cameras providing adequate views of the child’s actions. Video coding was done offline afterwards with The Observer XT software. After analyzing the data, they concluded that their series indeed elicited RDBM actions in toddlers as well as adults.
Observe behavior of infants
An infant won’t be able to fill out a long survey or communicate with an interviewer, so that rules out those possibilities for studies, leaving observational studies. For these studies, observation labs are extremely useful. Observe the infant in a setting similar to their natural environment unobtrusively, and be certain that your data is coded accurately and efficiently by using The Observer XT.
