Professor Kinon believes that focusing on mortality elicits more fear than focusing on an important exam. To examine his hypothesis, Professor Kinon randomly assigned 76 participants to answer 2 open-ended questions regarding death (mortality salience) and 90 participants to answer 2 open- ended questions regarding taking an important exam (exam salience). After writing about death or an important exam, participants answered 6-items related to fear; a fear score was created by taking the mean of these items for each participant (lower scores mean less fear; higher scores mean 91' he more fear). Items included: \"Afraid"; \"Scared"; \"Frightened , Nervous"; \"Jittery"; and \"Shaky." Did participants who answered two open-ended questions regarding death (mortality salience) exhibit significantly greater fear relative to participants who answered two open-ended questions about taking an important exam (exam salience)?

The Attributional Complexity Scale (Fletcher et al., 1986) is a 28 item Likert-scored measure. Responses range from 1 (Disagree Strongly) to 7 (Agree Strongly). Items include: \"I believe it is important to analyze and understand our own thinking process;\" \"I think a lot about the inuence that I have on other people's behavior;\" \"I have thought a lot about the family background and the personal history of people who are close to me, in order to understand why they are the sort of people they are.\" High scores mean greater complex thinking; low scores mean less complex thinking. Professor Kinon believes that on average people administered the Attributional Complexity Scale will score above the midpoint; the midpoint being 4. Is Professor Kinon right?
