  1. The Role Environment, Cognition and Hormones Play in Behavior

  2. OBJECTIVE 1 • Using one or more examples, explain the functions of two hormones in human behavior.

  3. Functions of Hormones • Produced in the Endocrine System • Enter the bloodstream, so they are slower reacting than neurotransmitters

  4. Adrenaline • Gland: Adrenals • Location: above the Kidneys • Function: Arousal, Fight/Flight

  5. Cortisol • Gland: Adrenals • Location: above the Kidneys • Function: Arousal, stress reaction, memory

  6. SW= slow wave sleep (non REM) • Locus CeruleusFR= pons, production of Noradrenaline (parasympathetic NS) • PyrimidalFR= neurons in the Frontal Lobe, Hippocampus and Amygdala responsible in plasticity and cognition • Lipolysis= the breakdown of fatty acids • Proteolysis= the breakdown of proteins into amino acids

  7. Melatonin • Gland: Pineal • Location: Mid Brain • Function: Sleep Regulation

  8. Oxytocin • Gland: Pituitary/Hypothalamus • Location: Mid Brain • Function: Attraction, bonding

  9. Testosterone/Estrogen • Gland: Gonads • Location: Testes; Uterus • Function: Sexual development, emotional response

  10. OBJECTIVE 2 • Discuss two effects of the environment on physiological processes. • Brain plasticity • Brain is physically sculpted by experience • Brain’s ability to adapt and accommodate experience • See Rosenzweig, Bennett and Diamond (1972): enriched versus impoverished environments resulted in differences in brain connectivity in rats • See also: Genie Case Study, Fetal Alcohol Syndrome, Addiction • http://www.youtube.com/watch?v=8Vo-rcVMgbI

  11. OBJECTIVE 3 • Examine one interaction between cognition and physiology in terms of behavior. • Davidson: Does Meditation Change Brain Activity (2004) • Subjects: 8 Buddhist monks and 10 novice meditators • Procedure: all were asked to meditate on love and compassion while in a PET scanner • Results: all monks and 2 novices showed increased GAMMA WAVES, brain activity linked to higher reasoning; soon after the test, novice gamma waves returned while the monk’s gamma waves stayed elevated showing brain plasticity due to practicing meditation • http://www.youtube.com/watch?v=m8rRzTtP7Tc

  12. The Mozart Effect (Raucher et al, 1993) • Claim: listening to complex musical compositions excites brain areas responsible for spatial tasks • Findings: spatial skill enhancement had little to do with the music itself, and more to do with arousal (Thompson, 2001: good mood = better spatial performance without musical influence)

  13. Mirror Neurons • Essential for observing others, social interactions, empathy • Gallese et al, 1996: mirror neurons in Rhesus monkeys • The same electrical signals were elicited in the brain when monkeys watched or performed movements.

  14. Iacoboni, 2004: Would looking at emotional faces cause similar brain stimulation in the viewer? • Yes: whether looking at face or making the face, the Nucleus Accumbens and Amygdala were activated just the same. • http://www.youtube.com/watch?v=Sv1qUj3MuEc
