Alfred Kinsey
 Considered
the father of the
study of human sexuality for
conducting his studies in the
1940’s.
 Studies showed that there
were wide variations in
“normal” sexual practices of
individuals and that
premarital sex was
commonplace.

1940s-1950s

Well

Sexual Response Cycle
 Following
Kinsey’s studies, scientists
looked to identify typical sexual reactions
among volunteers in the 1960’s.
 Master and Johnson filmed and identified
the sexual response cycle: refers to
the four stages of sexual response:
 1. Excitement
 2. Plateau
 3. Orgasm
 4. Resolution
Sexual Response Cycle
1. Excitement: blood flows to the genital
areas causing both sexes’ genitals to enlarge.
 2. Plateau: peak of the excitement phase;
breathing increases; penal and vaginal
secretions increase.
 3. Orgasm: ejaculation in the male and
vaginal contractions in the female.
 4. Resolution phase: body returns to
unaroused state. In males, enter refractory
period: resting period where they cannot
have another orgasm.

Hormones and Sexual Behavior
 Certain
hormones help activate sexual
fertility, putting animals in “heat.”
 Females become sexually receptive when
estrogen (sex hormone greater in
females) peaks during ovulation.
 Testosterone levels also effect sex drive
in both males and females.
 Hormones are monitored by
Hypothalamus.
Effect of External Stimuli on
Sexual Motivation
Studies
have shown that both
males and females are both
aroused by seeing, hearing, or
reading erotic material.
Some psychologists have argued
that sexual explicit materials can
have negative effects. How?
 Sexual
Sexual Disorders

consistently impairs sexual arousal or
functioning.
 In Men:

Ejaculation: ejaculation before

Sexual Orientation
Sexual
Orientation: an
enduring sexual attraction
toward members of either
one’s own gender
(homosexual orientation) or
the other gender
(heterosexual orientation)
Possible Causes of Homosexuality?
 Have
found brain differences between
heterosexual men and homosexual men
and women. Hard to get at causation.
 Identical twin brothers, 52% both will be
gay. Genes not everything.
 Prenatal exposure to certain hormones.
 Most psychologists believe that nature
more than nurture influences sexual
orientation but the answer has not been
completely solved.
Changing Attitudes towards
Homosexuality
 People
who believe homosexuality to be
biological tend to be more accepting.
