Psy 270 Week 4 Paper Worksheet Behavior

Our sample consisted of 43 undergraduate psychology students in a Learning and Cognition lab (Psy A355L) at the University of Alaska Anchorage. The participants were adults, but data was not collected on age, sex, or any other demographic. All the students provided their consent and time, in exchange for 15 points in the class. The ethical principles of the American Psychological Association were followed in this human experiment (American Psychological Association, 2010).
Materials
The participants used their own writing utensils to fill out the four paper worksheets that were provided (see appendix). Worksheet one was a series of six columns for the participants to write the words they remembered hearing. Worksheet two was a rating scale in which words were provided and the participant had to rate the likelihood that they believed a word was one of the words mentioned using a four point Likert scale in which 4=sure item heard, 3=probably item heard,

In the experimental group the middle four average scores were not significantly different (M = 0.70, SD = 0.04) from the last four average scores (M = 0.50, SD = 0.00), t(4) = 2.06, p < ns . In the control group, the middle four average scores were also not significantly different (M = 0.68, SD = 0.02) from the last four average scores (M = 0.56 , SD = 0.00), t(4) = 1.89, p < ns.The serial position curve of recall of the warned group and the control group showed a similar pattern as to the one found in previous studies on the same topic. Both groups were able to recall about 90% of the words in the beginning of the list and the end of the list (See Figure 1). The warned group had slightly more false memories, but the difference was not at all significant (see Figure 2). The control group recalled more critical and studied words than the warned group (see Table
