Answer:
Serial-position effect
Step-by-step explanation:
In psychology, the serial-position effect refers to the tendency of a person to recall the first and last items of a list best and to tend to forget the ones in the middle.
In this example, your manager introduces you to your coworkers by name. By the end you can better recall the names at the beginning and the last names you heard. In other words, you can recall the first and the last and you forgot the names of the members that were introduced to you in the middle. Therefore, the serial-position effect is what best explains this experience.
