Hi everybody.
00:07
So today we're going to be going over problem number three.
00:11
And this problem is testing our knowledge of the serial position effect.
00:24
So i think it's easy to demonstrate this phenomena in a graph.
00:28
So i'm going to draw a graph here.
00:34
Straighten this out.
00:39
So and basically this effect essentially proves a theory where items that are presented at the beginning of the list and items that are presented at the end of a list are actually better recalled than items that are in the middle of the list.
00:57
So i'm going to draw that out here.
01:00
So i'm going to label this axis as position in the sequence.
01:13
So the position of an item in a list.
01:16
And then i'm going to right here, percentage recall it.
01:25
And this will be 0 % recalled.
01:29
This will be 100 % recalled.
01:32
So the way the serial position effect is visualized is like so.
01:44
So here we have items at the beginning of the list.
01:48
Here are items at the end of the list...
