Research has shown that young children have difficulties inhibiting a prepotent response. A specific portion of the brain has been shown to play a significant role in inhibition
Name that brain structure, and describe one finding that illustrates the role of that brain structure in inhibition.
What will be an ideal response?
The frontal cortex has been shown to play a significant role in inhibition. Findings that illustrate the role of the frontal cortex in inhibition include the following: (1) toward the end of the first year, the frontal cortex shows substantial development, and during this time one also sees dramatic improvements on Piaget's A-not-B task in which babies must inhibit the tendency to reach to the location where an object was previously hidden; (2) adult monkeys with intact frontal lobes can succeed in the A-not-B task, but when their frontal lobes are removed or frozen, they lose the ability to succeed on the task; (3) between the ages of 4 and 7, the frontal cortex shows substantial development, and during this time one also sees dramatic improvements in the ability to inhibit a prepotent response (e.g., improvements in the ability to play Simon Says).
