chapter 3

Question 1

sexual psychophysiology study definition

Answer 1

• where relationship between physiological (ie genital blood flow) and subjective (arousal one feels) is studied

Question 2

Twain Bloch

Answer 2

• Published: The sexual life of our time in its relations to modern civilization (1906)
• more objective look at sexuality
• known as father of psychology
• sexuality as a continuum

Question 3

Kinsey Scale

Answer 3

• used combination of quantitative and qualitative methods to place individuals
• one of first times sexuality is seen as a spectrum
• scale of 0-6 (0=hetero, 3=bisexual, 6=homo)

Question 4

descriptive design studies examples

Answer 4

• observational
• case study
• interviews
• content analysis

Question 5

correlational design studies examples

Answer 5

• survey (one of best options due to honesty from anon and less likely volunteer selection bias)
• archival mining data

Question 6

vasocongestion

Answer 6

• increased blood flow in genitals when aroused

Question 7

sexual concordance

Answer 7

• agreement level between genital and subjective components of arousal

Question 8

t or f: vasocongestion is only the blood flow in relation to the vulva

Answer 8

false, for both male and female bodied people

Question 9

phallometry

Answer 9

• measuremnt of blood flow to penis/penile tumescence and/or temperature

Question 10

tumescence

Answer 10

swelling

Question 11

devices to measure vaginal/vulvar blood flow (not penile)

Answer 11

• vaginal photoplethysmography (VPP)
• Labial thermistor
• vaginal lubrication

Question 12

devices to measure both vaginal/vulvar and penile blood flow

Answer 12

• thermographic cameras
• doppler ultrosonography
• Laser doppler imaging (LDI)

Question 13

vaginal photoplethysmography (VPP) overview

Answer 13

• acrylic, tampon shaped probe that fits in vagina
• emits infrared light that hits wall of vagina and is reflected back to photosensitive detector in the device
• produces vaginal pulse amplitude
• more light = more arousal

Question 14

devices to measure penile blood flow (not vulvar/vaginal)

Answer 14

• penile volume plethysmography
• penile strain gauge
• penile photoplethysmography

Question 15

Labial thermistor

Answer 15

• sensor that provides measure of surface temperature
• attached to labia skin via metal clip
• baseline can be used (37°C)
• less invasive

Question 16

vaginal lubrication

Answer 16

• litmus test strip w/ plastic applicator placed at entrance of vagina for 1 minute following sexual stimulation
• length of colour change on paper=lubrication amount
• immediate

Question 17

vaginal photoplethysmography (VPP) cons

Answer 17

• not fully proved
• low sexual concordance rates
• no baseline for vaginal blood flow

Question 18

Labial thermistor cons

Answer 18

• takes time (over several minutes) to detect change

Question 19

thermographic cameras

Answer 19

• heat sensing camera that remotely record genital temperature
• surface temperature reflects change in blood flow
• comparable results (accurate)

Question 20

thermographic cameras cons

Answer 20

• takes time to show change (over minutes)
