When pаrticipаnts аre presented with a list оf items tо remember, there are twо common methods for testing memory. A recall test simply asks each person to report as many items as s/he can remember. In a recognition test, participants are shown a list of items and asked to identify which items they remember from the first list. Typically, recall performance is very poor in young children, but improves gradually with age. Recognition performance is generally good for all ages. A researcher wants to further explore this phenomenon. She recruits children who are either 3 years old, 6 years old, or 10 years old. Half of the children within each age group complete a recall test and the other half complete a recognition test. What overall test will tell the researcher if memory varies by age, if the number of words remembers varies by the type of test, and whether the effect of the type of test used on the number of words remembered depends on the age of the participants?
