Answer:
The correct answer would be, Proactive Interference.
Explanation:
When the previously remembered things hinder the subsequent learning, the process is called as the proactive interference. Proactive interference is when you memorize some data or information like words, names, ideas, formulas, and then memorizing the other things, an earlier memorized part of the learning gets in the way.
So in this question, when Tim tries to memorize other things after the study of 6 to 7 hours, he feels that he is unable to memorize the current things but he surely remembers the previously learned things, he is actually having a memory problem which is best explained by Proactive Interference.
