question 149

Multiple Choice

Suppose an infant has learned to wave his or her arm to activate a video display.A few weeks later the infant does not respond an arm wave when exposed to the display until the display is briefly illuminated.What would such an observation imply with respect to the infant's learning and memory processes?

• A)The infant had not really learned the arm-wave response earlier.
• B)The infant had learned the arm-wave response, but no permanent memory of the association of the wave and the illumination of the display was stored at the time of learning.
• C)The infant had learned the arm-wave response, had stored it in memory, but had difficulty retrieving it when required.
• D)The infants must relearn operant responses such as the arm-wave response, each time they are exposed to a stimulus if the time since original learning is greater than three days.
