Quizplus · Accepted Answer

The dorsolateral prefrontal cortex is responsible for planning and executive cognitive functions, such as working memory and attention. Damage to this area can result in difficulty in planning, organizing, and problem-solving, as well as difficulty in retaining and manipulating information in short-term memory. This would explain Clare's difficulty in remembering the new friend's telephone number long enough to put it in her cell phone.  Both the amygdala and hippocampus are involved in memory formation, but not necessarily in planning and executive cognitive functions. The posterior cingulate cortex is involved in the default mode network and self-referential processing, but not necessarily in planning and executive cognitive functions.
