Answer:
Serial-position effect
Step-by-step explanation:
Serial-position effect is a tendency to recall or remember the first and the last items in a series best. The term was invented by Hermann Ebbinghause , he studied peoples' recall capabilities by asking them questions on what they remembered first from a given list. In turned out that people recalled items at the top and the bottom of a list best and items in the middle worst.
The first item is always the easiest to remember because is it the first to be stored in the dormant memory. The following item is stored together with the first one, the third one with the second one, etc. The last item is sored differently as well as the dormant memory 'feels' it's important and it's remembered longer for that reason.
