The serial position effect includes the primacy <em>and<\/em> recency effects. However, because of the requirements of the IA you should study <strong>one!<\/strong><\/p>\n<p>Which one? Well, I don&#8217;t want to give you all the answers, but you should be able to figure it out. Your independent variable in this study is the delayed or no delay, right? Take a look at the line graph. The delay only affects the primacy\u00a0<em>or\u00a0<\/em>the recency effect. Figure out which one and that&#8217;s what you should focus on because you don&#8217;t want to have two conditions in your experiment that you&#8217;re hypothesizing will have the same results.<\/p>\n<p><strong>Operational definitions:\u00a0<\/strong>Remember what your independent variable (IV) is &#8211; it&#8217;s the delay. Therefore, be specific. Exactly how long is the delay in the DRF (delayed free recall) condition and when do participants recall in the IFR (immediate free recall). Misidentifying the IV is a common error that must be avoided. To repeat: it&#8217;s the delay\/no delay that you should be manipulating, not the words in the sequence or the sequences of words . These will be consistent across both groups.<\/p>\n<p>For your dependent variable (DV), be clear in what you mean by &#8220;recall.&#8221; Does this mean verbally, in writing, identifying? Operational definitions require you to be specific.

It&#8217;s important that your introduction begins with a clear and accurate (and well-referenced) summary of Atkinson and Shiffrin&#8217;s multi-store model. You should also define the key terms primacy and recency effect. You can then explain the connection in one of two ways:<\/p>\n<ol>\n<li>Use the MSM to explain why the recency effect disappears after a delay<\/li>\n<li>Use the recency effect&#8217;s disappearance after a delay as support for the claims of the MSM\n<ol>\n<li>(Hint: the concepts of rehearsal, STS-LTS and the capacity of the STS are needed to understand and explain this clearly).<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<p>Later in your introduction you can make the link clear between your own investigation and the MSM by stating how your aim is testing one of the claims of the model.

The most effective explanations are those that explain materials related to their manipulation and\/or measuring of their variables. In this case, a common mistake is students state that they use a word list but they don&#8217;t take the time to explain how they created their word list and why they did it this way. For example, was a random word generator used? If so, which one and why use a random word generator?<\/p>\n<p>Having a list of words that are different in each position could confound the results. For example, having some long or short, some easy or hard, some familiar or unfamiliar in the beginning and not in the end could be a confounding variable.<\/p>\n<p><strong>The recency effect is an\u00a0<em>effect\u00a0<\/em>not a cause: <\/strong>Because you&#8217;ve chosen (I hope) to do the recency effect you must remember that it does not cause an effect \u2013 the <em>delay<\/em> causes the recency effect.

I recommend giving them descriptive titles that make it easier. For example, you could simply call them the &#8220;Delay&#8221; and &#8220;No Delay&#8221; conditions.
