Instinct theory
We are motivated by our inborn automated behaviors
Drive reduction theory
Our behavior is motivated by biological needs. Ex. Food is good. Hunger is not. Hunger DRIVES us to seek out food.
Arousal theory
We are motivated to seek an optimum level of arousal.
Yerkes-Dodson Law
People perform best at intermediate levels of arousal, and that performance is lower at high or low levels of arousal.
Maslow’s hierarchy of needs
(From bottom to top) Physiological, safety, belonging and love, esteem and self actualization.
Lateral hypothalamus
Makes you hungry when stimulated. If leisoned, you will never feel hunger again.
Ventromedial hypothalamus
When stimulated, you feel full. If leisoned, you will always be hungry.
Set point theory
The hypothalamus acts like a thermostat and wants to maintain a stable weight.
Glucose’s role in hunger

Sexual response cycle
The four stages of sexual responding as described by Masters and Johnson:
- Excitement
- Plateau
- Orgasm
- Resolution (refractory)
Excitement phase of sexual response cycle
Genital areas become aroused and engorged with blood, preparing
Plateau phase of sexual response cycle
Breathing, pulse, and blood pressure rates continue to increase.
Orgasm phase of the sexual response cycle
Muscles all around the body contract to either aid the capture of male semen, or to aid the ejaculation itself.
Resolution phase of the sexual response cycle
Body returns to homeostasis – this is the period in which males cannot experience another orgasm until after the refractory period.
Refractory period
A resting period after orgasm in which a man cannot achieve another orgasm. Can be a few minutes, or a day or more.

Estrogen
A sex hormone secreted in greater amounts in females than males. Estrogen levels peak during ovulation, promoting sexual receptivity.
Testosterone
The most important of the sex hormones. Males and females both have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the male sex characteristics during puberty.
