Irene Conducts a Laboratory Experiment to Test the Memory of Children

question 161

Multiple Choice

Irene conducts a laboratory experiment to test the memory of children. She rapidly reads out a list of colors to three children aged 4, 6, and 13 years. The children are then asked to repeat the names of the colors. Irene notices that the 6-year-old and the 13-year-old are able to recall more colors than the 4-year-old. This experiment illustrates that

• A) younger children tend to rehearse information more than older children do.
• B) short-term memory decreases during late childhood.
• C) information is retained in short-term memory for a long period without rehearsal.
• D) memory span varies from one individual to another.
