Answer:This is an example of:Retroactive interference
Explanation:
Interference refers to how we forget information stored in our long term memory because there is an interference between memories which distract one another; other information interfere with other restored Information.
There are two ways in which interference result to forgetting:
1) Retroactive interference this interference occurs when we acquire new information we tend to forget the previous one , new learning eliminate our past learned tasks or information;new memory interference with the old memory.
This is the reason why Mr Musselman is finding it hard to recall the last year player because the current year players names interfere with the names of the previous players in his memory.
2. Proactive interference this one prohibit us from learning new information due to the existing old information.
These interference occur mostly due to similarities between these memories or becaue memories are similar , the old and the new memory.
