reservoir of mostly unacceptable thoughts, wishes, feelings and memories according to Freud

• Operates on the pleasure principle
• * think of dog humping leg**
• Know's what it wants and wants it now

• -seeks to gratify id's impulses in realistic ways
• mediated demand of the id, superego and realisty

• part of personality that represents internalized ideals, and provides standard judgements and for future aspirations
• "voice of the unconscience"

• Phallic (3-6 yrs)
• Latency (6- puberty)
• Genital (puberty onward)

children incorporate their parents' values into their developing superegos

According to Freud

If conflicts in early psychosexual stages aren't resolved, fixation occurs, on whatever pleasure seeking stage it is at...

ak conflict in oral stage, fixation may be sucking thumb

• banishes anxiety-arousing thoughts, feelings, and memories from consciousness.
• -think insomnia, forget bad experiences

• an individual faced with anxiety retreats to a more infanitile psychosexual stage
• ex) 1st day of school anxiety brings old thumb sucking from oral stage

• ego unconsciously switches unacceptable impulses into their opposites
• ex) unaccepatble "I hate him" becomes "I love him"

*think reaction is the opposite of what you'd think"

method of exploring the unconscious in which the person relaxes and says whatever comes ot mind, no matter how trivial or embarrising (psycho analysis)

• disguise threatening impulses by attributing them to others
• ex) "He doesn't trust me"--> "I don't trust him" ---> " I don't trust myself"

**think it's gonna be a project to get him to trust me**

• ex) I drink only to be socialable, thats all

*think rationalize as in make up reasons for your actions*

• shifts sexual/aggressive impulses toward a more acceptable or less threatening object or person
• ex) kicking dog, snapping at roommate

• Carl Jung's concept of a shared, inherited reservoir of memory traces from our species history

process of watching and then imitating a specific behavior and is thus an important means through which observational learning occurs

found in brain's frontal lobe, may be neural basis for observational learning. These neurons generate impulses when certain actions are performed on when another individual who performs those actions is observed

• "split brain"

busy, branches, receives messages from nerve cells

the extension of a neuron that sends impulses to nother nerve cells or to muscles or glands

fatty tissue that covers axons and helps speed neural impulse

neural impulse generated by movement of pistively charged atoms in/out of chanels of axon's membrain

level of stimulation must be exceeded for a neuron to fire

muscle action/movement, attention, arousal, memory

*too little causes alzheimers

natural, opiate like neurotransmitters linked to pain control and pleasure

• mood, emotion, arousal, learning
• *too little Parkinson's
• *too much Schizophrenia
• *linked wiht cocaine nad amphetamines

• mood, arousal, learning
• *too little, depression

• sleep, hunger, agression, arousal
• *too little, depression
• *too much, anxiety, inhibit dreaming

• inhibitory effect on axon's
• sleep, movement
• * too little Huntingtons disease,seizures
• *alcohol increases GABA

• excitatory effect on axons/neurons
• alcohol blocks glutamate

fun, creative, artsy, music

structure, language and logical math reasoning

brain, spinal cord

• sensor and motor neurons that connect the central nervous system to body's receptors, muscles and glands,
• splits into autonomic and somatic nevous systems

• self-regulated action
• breathing
• controls internal functioning

voluntary control of skeletal muscles

arousing, alert, flight or fight

calming, conserves energy,

• under influence of hypothalamus, regulats growth and controls endoctrine system
• "master gland"

produce epinephrine and nonepinephrine, hormoones that prepare body to deal with emergencies or stress

chemical messengers, manufactored by endoctrine glands, produced in one tissue and circulate through the blood stream to to their target tissues
