Answer:
This is serial position effect.
Step-by-step explanation:
Serial Position effect is a memory-related term. It means that a person can recall information that is presented to him in the beginning and at the end. The information in the middle is less likely to be recalled in comparison.
This is majorly because of the preservation of information in our memory, i.e. the part the memory which is conscious. Thus, as per question, if the person remembers the names of his coworkers in the office introduced to him in the beginning and towards the end, this experience is due to serial position effect.
