Final answer:
The anthropology professor's difficulty in remembering names due to confusion with past students' names is an example of proactive interference, where old information impedes the recall of new information. The correct option is c. Proactive interference
Step-by-step explanation:
The anthropology professor is having trouble remembering the names of her current students because they are getting mixed up with those of her past students.
This problem is an example of proactive interference. Proactive interference occurs when old information hinders the recall of newly learned information.
This is in contrast to retroactive interference, which involves new information interfering with the recall of older information.
The issue the professor is experiencing is not related to retrograde amnesia, which is the loss of memory for events that occurred prior to brain trauma. The correct option is c. Proactive interference
