1.Thinking that hearing about a gun might be more emotionally stressful for females then males, the researchers made sure that all female participants were in the control condition while males heard the conversation about the presence of a gun. The researchers found that those in the experimental group did incorporate the gun misinformation into their memories of the theft more than those in the control condition. That is, the mean score that a gun was present was much higher for the experimental groups (M = 67%, SD = 12.4%) than the control group (M = 33%, SD = 11.16%).

2.The researchers decided to collect all of the data from the control group early in the semester and then collect data from the experimental group later. Although the researcher scripted out exactly how the confederates were supposed to act for both conditions and what they were supposed to say, the confederates were still shy and nervous early in the semester. Fortunately, they grew much more confident in their performance as the semester progressed. The researchers found that those in the experimental group did incorporate the gun misinformation into their memories of the theft more than those in the control condition. That is, the mean score that a gun was present was much higher for the experimental group (M = 67%, SD = 12.4%) than the control group (M = 33%, SD = 11.16%).
