Final answer:
Tina's return to knitting after a hiatus is an example of relearning, which is a retrieval process where information previously learned is more quickly reacquired.
Step-by-step explanation:
Tina's experience of wanting to knit again after college and practicing until she regained proficiency is an example of relearning, a means of retrieving information out of your long-term memory storage system. Relearning is the act of learning information that you had previously learned and retained in your long-term memory. Over time, even after ceasing to practice a skill, the brain retains a residue of the skill, and relearning typically happens faster than the original learning because the foundational neural pathways formed during the initial learning phase are reactivated.
Tina's scenario is an example of relearning, which is a means of retrieving information out of the long-term memory storage system. Relearning involves learning information that was previously learned.
