Dr. Alimam is studying infants' ability to distinguish shapes. He shows an infant a shape until the infant loses interest in the shape, and then he shows the infant a different shape. If the infant shows interest in the new shape, he determines that the infant recognizes that the new shape is different from the old one. Dr. Alimam expects that getting older will cause the babies to recognize shapes faster. He records how long it takes the infant to show interest in the new shape. Dr. Alimam conducts the study using a group of 5 three month olds, 5 six month olds, and 5 eight month olds recruited from local day-care centers. Because he knows the directors, he does not contact the infants' parents to inform them of the study. Below is a chart that shows the time it took for each infant to show interest in the new shape Dr. Alimam concludes that eight-month-old infants are better at recognizing different shapes than three month olds or six month olds. Age Infant 1 Infant 2 Infant 3 Infant 4 Infant 5 Three 15 12 15 20 30 seconds seconds seconds months seconds seconds Six 10 7 seconds 6 seconds 8 seconds 10 seconds months seconds 3 seconds 2 seconds 5 seconds 1 seconds 3 seconds Eight months Describe how the data illustrate the habituation process. • Identify the mode for three-month-old infants Describe the correlation between time and an infant's age. • Identify the dependent variable. Describe how Dr. Alimam could use replication to conduct a better-designed study. Explain how the data support or do not support the hypothesis. Suppose Dr. Alimam covered the shape with a towel as the infant was exhibiting interest. Explain what would most likely be a key difference in the way the three-month-old infants would react toward this versus the way the eight-month-old infants would react.
