Methods:Stimulus and Task Design

4 world lists; 12 words per list

Serially presented at 2 sec. per word

60-seconds free recall time after each list

Non-target word font, size,color: Arial 24 black

Target word font, size, color: Comic Sans bold 54 purple

Methods:Stimulus and Task Design

Target word: Item 5-8, avoid primacy or recency effects from beginning and end of list, respectively.

Target position: sampling randomly without replacement

All words were of same frequency of use

Instructions(Paraphrase this, don’t quote!): presented 4 word lists of 12 words each. After each list, write down as many words as possible. Don’t write anything until the end of each word list.

Methods: AnalysisItems 5-8 analyzedFor each participant:

1. mean % recall of 4 target words2. mean % recall of remaining, non-target

words (3/list x 4 lists = 12 items)generating 2 distributions for comparison

Within-subjects designStudent’s t-test, alpha p < 0.05

n.b.: (You are permitted to include the following passage verbatim, and must state something to this effect, for accuracy): For the first group of participants (N=18), one of the non-target words from position 5-8 of list 4 had erroneously occurred earlier in the list, and was consequently discarded from analysis. Thus, for this group, only 2 non-target words were averaged from the 4th list.
