This dataset comes from research conducted by Dr. Lincoln Craton, who has been investigating cognition during infancy. In this study, he was interested in understanding infants’ ability to perceive stationary, partially hidden objects. He presented infants of various ages the scenes depicted in the figure on the next page. When shown the top left panel, most adults report seeing a vertically positioned rectangle behind a long horizontal strip. What do you suppose a 5- or 8-month-old infant sees here? Infants in this study were presented with the two test events shown above. The primary dependent variable in this study was looking time. Prior research has shown that infants tend to look longer at the more surprising of two events. Do infants find the broken event to be more surprising, as adults do, who have a strong tendency to perceive partially hidden objects as complete? Do 5-month-old infants perceive a partially hidden object as complete? First, select infants who are between 5 and 6 months old (defined here as between 500 and 530 in age; 500 is read as 5 months and 00 days). Compare these infants’ total looking-time at the broken event (totbroke) to their total looking-time at the complete event (totcompl). Is there a significant difference? What does this result mean?
