Experiments

Below you will find descriptions of two types of experiments. Click on the images below to see photos of these experiments.

 

Width
The purpose of this experiment is to examine 3.5-month-old infants' ability to reason about the width of an object relative to an occluder (a screen) or a container (a box). This experiment also indirectly addresses whether or not young babies believe objects continue to exist when they pass out of view.

 

Containment & Covering

These experiments investigate the possibility that when babies reason about the height of an object, they may be able to do so in the context of one event category such as occlusion or containment, but not in another, such as covering. For example, 3.5 month olds are able to reason about height in an occlusion event, but it is not until they are 7.5 months old that they are able to reason about height in a containment event. Furthermore, it is not until they are 12 months old that they can reason about height in a covering event.
