Scenario 2

An evolutionary psychologist is interested in whether there are differences in how people identify emotions when they are extremely tired. For the present study the researcher recruits 50 participants who had no sleep in the past 24 hours.

Prior to measuring emotions the research participants were deprived of sleep for 24-hours. A specific, valid and reliable method for measuring emotions is used for the study. This method has known accuracy ratings of people in the general population that are normally distributed with a = 82. The mean accuracy for the sample (n =50) was M = 78.

Emotional recognition has been studied extensively and the measurement method is widely accepted in the psychological literature. The evolutionary psychologist is very concentered about making a Type I error. Using the information provided, plan your analysis in such a way that you will minimize the risk of making a Type I error.
