Question: An habituation task is often used to test the memory for infants. In the habituation procedure, a stimulus is shown to the infant for a brief period, and the researcher records how much time the infant spends looking at the stimulus. This same procedure is repeated again and again. If the infant begin to lose interest in the stimulus (decreases the time looking at it), the researcher can conclude that the infant “remembers” the earlier presentations and is demonstrating habituation to an old familiar stimulus. The data for such an experiment is presented in table 3

Use an ANOVA with a=.01 to determine whether there is a significant change in behavior for successive presentations. (2 pts)

Compute the h² to measure the effect size of the presentations. (1pt)
