STAS2126 Assignment#6 (Fall 2008) Please use your first and last name as file name for each assignment…DO NOT USE # SYMBOL Submit assignment through Dropbox Questions for “Heightened Sexual Arousal” 1. What was the major hypothesis for this set of studies? ( just above Experiment 1) The present series of experiments is designed to test the notion that an attractive female is seen as more attractive by males who encounter her while they experience a strong emotion (fear) than by males not experiencing a strong emotion. 2. What would be the null hypothesis in this study ( it’s NOT stated in report )? Males who experience a strong emotion (fear) and males not experiencing a strong emotion will rate a female they encounter as equally attractive…OR whether males were interviewed on the tall bridge or small bridge, there will be no differences in attraction to the interviewer 3. What was the total sample size and was there random assignment (did the researchers CONTROL who crossed the low or high bridge)? Sample size = I accepted several different answers because the report was unclear with respect to sample size There was no random assignment….the researcher did NOT control or determine who would cross the high suspension bridge and who would cross the low bridge…in any study where random assignment is used, the researcher will mention in the method section if random assignment was used 4. Attraction to the interviewer was measured in two ways (in other words there were TWO major dependent variables). Briefly describe these two measures. (see page 511 right side and 512 left side) (1) Stories written in response to the TAT were later scored for sexual content (2) A second measure of sexual attraction was the number of subjects who called the interviewer. In the experimental group 9 out of 18 called, in the control group 2 out of 16 called 5. Were the interviewers aware of the experimental hypothesis? Why is this important? (HINT: Bias) The interviewers were not aware of the experimental hypothesis in order to prevent unintentional differential cueing of subjects in experimental and control groups.…any differences in interviewer behaviour could influence the results 6. Subjects were asked: "How fearful were you while crossing the bridge?" Report t-test results and explain them (p. 512, left) In response to the question "How fearful were you while crossing the bridge?" experimental-bridge males gave a rating of 65 and control-bridge males a rating of 3 (t = 10.6, p < .001, df = 28, two-tailed). Hence, it can be concluded that most people are quite anxious on the suspension bridge but not at all anxious on the low bridge. 7a.
