Q

Incentive

A positive or negative environmental stimulus that motivates behavior.

Positive incentives cause underlying drives to become active impulses. When this aligns with a need, we feel strongly driven.

Negative incentives motivate us to change.

Q

Estrogens

A

Sex hormones, such as estradiol, that contribute to female sex characteristics and are secreted in greater amounts by females than by males. Estrogen levels peak during ovulation. In nonhuman mammals, this promotes sexual receptivity.

21
Q

Sex Hormone Fluxuations

A

Females: prenatal, puberty, after puberty
Males: puberty

  • In both genders, sexual interest is often correlated to their sex hormone. Hormonal surges occur during the pubertal stage, later in life, and due to some surgeries.
22
Q

Sexual Response Cycle

A

The four stages of sexual responding described by Masters and Johnson—excitement (filling/expanding), plateau (rates increase, filling stops, secretion begins), orgasm (muscle contractions, rates increase to max), and resolution (returns to unaroused state).

23
Q

Refractory Period

A

In human sexuality, a resting period that occurs after orgasm, during which a person cannot achieve another orgasm.

24
Q

Sexual Dysfunction

A

A problem that consistently impairs sexual arousal or functioning at any point in the sexual response cycle.

25
Q

Erectile Disorder

A

Inability to develop or maintain an erection due to insufficient blood flow to the penis. Another disorder that occurs in men is called pre-mature ejaculation.

*Treated with therapies

26
Q

Female Orgasmic Disorder

A

Distress due to infrequently or never experiencing orgasm.

*Treated with therapies

27
Q

Paraphilias

A

Sexual arousal from fantasies, behaviors, or urges involving nonhuman objects, the suffering of self or others, and/or non-consenting persons.

28
Q

Sexually Transmitted Infections

A

Infections that are transmitted orally or genially.

29
Q

AIDS (acquired immune deficiency syndrome)

A

A life-threatening condition caused by the human immunodeficiency virus (HIV), a sexually transmitted infection. AIDS depletes the immune system, leaving the person vulnerable to infections.

Q

A
  • humans can become aroused when they read, see, or hear erotic material
