  2. SEX SURVEYS - METHODOLOGICAL PROBLEMS 1) PURPOSEFUL DISTORTION 2) ABILITY TO REMEMBER 3) ABILITY TO ESTIMATE 4) COST

  3. ALFRED KINSEYPioneer of the Sex Survey •SEXUAL BEHAVIOR IN THE HUMAN MALE (1948) •SEXUAL BEHAVIOR IN THE HUMAN FEMALE (1953)

  4. Kinsey’s Method • 100% Sampling Technique • Face-to-face interviewing • Rapid fire questioning • Anonymity

  5. Results from a Survey of Illinois 4-Year University Students

  6. Results from a Survey of Illinois 4-Year University Students

  7. Results from a Survey of Illinois 4-Year University Students

  8. The last time you had sex, what form of birth control did you use? Female College Students in Illinois

  9. Male CollegeStudents in Illinois The last time you had sex, what form of birth control did you use?

  10. Clinical Studies William Masters & Virginia Johnson

  11. Human Sexual Response (1966) • 694 people studied • males - ages 21-89 • females - ages 18-78 • Mostly medical students • Medical View of the sample - the processes observed assumed to be normative

  12. Technology for Sex Research Penile Strain Gauge

  13. Technology for Sex Research Vaginal Photoplethysmograph

  14. Technology for Sex Research Vaginal & Rectal Myographs

  15. Advantages & Disadvantages of Masters & Johnson’s methods • Sophisticated technology • Sampling problems • “Unnatural” laboratory setting • Direct observation: No self-report problems

  16. Quasi-Experiments • Some Important Characteristics of Real Experiments: Manipulation, Control, Random Assignment, Systematic Measurement • Why “Quasi”? ---You can’t manipulate gender.

  17. Design of Heiman’s Quasi-Experimental Study Manipulations of story content: Crossed with this matrix of manipulations was the gender of the participant

  18. Two Types of MeasuresUsed in Heiman’s Study • Physiological • Self-Report

  19. Results from Heiman’s Study • Explicit sex was most arousing for both men and women • Female-initiated/female-centered scenarios were most arousing for both men and women • When physiological measures indicated that women were aroused 1/2 failed to report it
