Question

question 5 (1 point)
why cant adults remember events from their early childhood, such as their second birthday?

o a because the basal ganglia block early memory retrieval
o b because the cerebellum stores short - term memories only
o c because the amygdala repressed emotional memories
o d because the hippocampus and frontal lobes were not yet fully developed

question 6 (1 point)
why are emotionally charged events, such as the morning of september 11, 2001, often vividly remembered?

o a because sleep immediately follows emotional events
o b because the basal ganglia store emotional memories
o c because stress hormones activate the amygdala, enhancing memory
o d because the hippocampus shuts down to reduce stress

Explanation:

For Question 5: The hippocampus is crucial for forming long - term memories, and in early childhood, it (along with frontal lobes which are involved in higher - order cognitive functions related to memory processing) is not fully developed. The basal ganglia are more related to motor control and some learning aspects, the cerebellum is mainly for motor coordination and some non - declarative memory aspects, and the amygdala is about emotions but not the main reason for lack of early childhood memory.
For Question 6: Stress hormones (like cortisol) activate the amygdala. The amygdala can enhance the consolidation of memories, especially emotional ones. Sleep following an event is not the main reason for vivid memory of an emotionally charged event. The basal ganglia are not the primary structure for storing emotional memories in this context, and the hippocampus does not shut down to reduce stress in a way that enhances memory of such events.

Answer:

Question 5: d. Because the hippocampus and frontal lobes were not yet fully developed
Question 6: c. Because stress hormones activate the amygdala, enhancing memory
