Answer 1

Answer:

Stress hormones at the time of learning __interferes___ new memory formation; the presence of stress hormones at the time of recall _impairs____ retrieval of older memories.

Explanation:

When stressed, the human body produces some stress hormone. Some of these hormones can affect certain parts of the brain, interfering with the encoding of new memory,  and inhibiting the recall of long term or older memories. An example of a stress hormone responsible for negatively affecting long-term, delayed recall memory is the cortisol, and the effect is usually felt at the hippocampus, prefrontal cortex and the amygdala.
