  2. External Stimuli: Peripheral Arousal System
    - Cues from skin, genitals.. Basically when touching you become aroused.
  3. Excitement Phase (M&J) (Female)
    - Vasocongestion and other changes in the genital region

    - Vagina becomes lubricated with an alkaline fluid
  4. Plateau Phase (M&J) (Female)
    - Increased changes in the vagina

    - "Orgasmic platform" is created

    - Breasts may become swollen and nipples may become erect

    - Increase heart rate, respiration, and blood pressure
  5. Excitement Phase (M&J) (Male)
    • - Vasocongestion leads to erection of the penis
    • - Muscular tension increases throughout the body
  6. Plateau Phase (M&J) (Male)
    • - Testes may increase in size by 50%
    • - Cowper's glands often secrete fluid
    • - Glands of the penis become swollen
    • - Increased heart rate, respiration, and blood pressure
  7. Orgasm (M&J) (Male)
    • - Strong muscle contractions at base of penis and anal area
    • - Semen is expelled
    • - Pleasurable feelings throughout the body
  8. Resolution (M&J) (Male)
    • - Body returns to unexcited state, process may take two hours
    • - Drowsiness and relaxation
  9. Masters & Johnson's Four- Stage Model
    Excitement stage, Plateau stage, Orgasm stage, & Resolution stage.
  10. Libido
    - Sex drive
  11. Limbic System
    - Controls emotional behavior

    Deisre stage, Excitement stage, and Orgasm stage.
  13. Interactive Models
    • . Byrne's Models

    • . Barlow's
    • - Anxiety inhibits sexual functioning

    • . Bancroft's Model
    • - Central nervous system (COS)
    • - Psychosomatic circle of sex
  14. Cognitive Models
    - Sensory input must be interpreted as sexual before it can lead to arousal

  15. The Nervous System: Central Nervous System
    • - Brain
    • - Spinal Cord
  16. Organizing Effects
    - Control development of sex glands, external genitals, and nervous system in the fetus.
  17. Activating Effects
    • - May activate or deactivate sexual behavior

    - Posses gonads of one gender but external genitalia that are ambiguous or typical of the other gender.
  28. Congenital adrenal hyperplasia
    - Also known as adrenogenital syndrone

    - Genetic defect that causes the adrenal glands to produce to mush testosterone

    - Males reach puberty early

    - Females have masculinized genitalia
  29. Androgen Insersitivity Syndrone
    - Testosterone has no effect on target cells

    - Males Woflian system does not develop but mis prevents mullarian devlopment as well

    - Females little effect in development
  30. DHT Deficiency Syndrone
    - Undescended testes and underdeveloped penis

    - Give the appearance of a vagina and clitoris as juvenile, but will develop male secondary sex characteristics at puberty

    - Rare but in us many have been surgically altered and raised as females
  31. Stereotypes

    - Undifferential-ed individuals are the most poorly adjusted

    - Traditional males and females, adjustment depends on situational context
  34. Gender Assignment
    - Labeling of newborn as male or female based on biological features
  35. Nature (Biology) or Nurture (Enviornment)
    - Both seem necessary to complete the process of gender identity
