Question

Question: A habituation task is often used to test the memory for infants. In the habituation procedure, a stimulus is shown to an infant for a brief period, and the researcher records how much time the infant spends looking at the stimulus. This same procedure is repeated three times. If an infant begins to lose interest in the stimulus (i.e., decrease in the time looking at the stimulus), the researcher concludes that the infant “remembers” the earlier presentations and is demonstrating habituation to an old familiar stimulus. The data for the experiment is provided below:

Amount of time (in seconds) Looking at the Stimulus
Infant	1st Presentation	2nd Presentation	3rd Presentation
A	112	81	20
B	97	35	42
C	82	58	27
D	104	70	39
E	78	51	46
