1. Lets return to Danikas birthday party to answer Susans question regarding the educational benefits
of infant-directed media programs. Explain the study results to Grandma Jones and Susan,
Danikas mother. Be sure to describe how the study was conducted (type of research study, who the
participants were, the four different conditions, and the dependent variable).
2. Parents often think that spurts in word learning are the result of exposure to infant-directed media
programs. Given your understanding of the scientific method and the research findings from this
study, first explain why parents may misattribute ordinary developmental progress to these infantdirected
media programs. Second, explain why parents shouldnt give credit to these programs for
the rapid increase in vocabulary between the first and second year of life. Third, based on this study,
which parents are most likely to misattribute ordinary developmental progress to these programs?
3. Your best friend, Giselle, had a baby last year. Giselle and her husband are interested in buying
several infant-directed DVDs to promote their babys language development. They know that you
are taking a psychology course, so they ask for your advice. How would you respond to your best
friend and her husband?
