|
|
Wilhelm Wundt |
made psychology its own scientific discipline that uses the scientific method. |
|
|
William James |
encouraged exploration of function of emotions and consciousness. Wrote “principles of psychology” |
|
|
Structuralism |
Study of mind in terms of the simplest definable components and then to find how these components fit together to form more complex experiences. Focuses on the purpose of consciousness. |
|
|
Behaviorism |
Studies observable behavior. Environment leads to all our behavior. |
|
|
Functionalism |
Explores functions of emotions, memories, willpower, habits, and streams of consciousness. Things studied by William James |
|
|
2 Parts of nervous system |
Peripheral Central |
|
|
Somatic |
Part of peripheral nervous system that controls willed body functions |
|
|
Autonomic |
Part of peripheral nervous system that controls automatic body functions |
|
|
Action Potential |
The electric signal arising in a neuron’s axon (the “wire”) |
|
|
How the neuron transmits a signal |
sodium is let into the cell through a gate which increases the action potential. Next, a potassium gate opens to lower the action potential. |
|
|
EEG |
an amplified recording of the waves of electrical activity sweeping across the brain’s surface |
|
|
Pet Scan |
Patient injects radioactive substance, that shows blood flow* in brain. |
|
|
MRI |
uses magnetic fields and radio waves to reveal soft tissue |
|
|
FMRI |
like an MRI, but shows blood flow* as well. |
|
|
Medulla |
Part of brain stem. Controls heartbeat and breathing |
|
|
Pons |
Part of brain stem. help control movement and sleep |
|
|
corpus callosum |
where the two halves of the brain meet |
|
|
Thalamus |
Sensory control center |
|
|
Cerebellum |
Judges time, modulate emotion, discriminate sounds and textures, and controls involuntary movement |
|
|
Limbic System |
Hippocampus Amygdala Hypothalamus |
|
|
Hippocampus |
Conscious memory |
|
|
Amygdala |
fear and agression |
|
|
Hypothalamus |
Regulates needs (hunger, thirst, sex) |
|
|

|
|
Right side of the brain |
pictures and stuff |
|
|

daily biological clock |
|
|
Brain waves while relaxes |
alpha waves |
|
|
brain waves while alert |
beta waves |
|
|
sleep cycle |
1: light sleep 2: slow heart rate, random brain activity 3: deep sleep, slow brain waves 4: dreams, muscular paralysis, high brain and body activity |
|
|
Sleep disorders |
Insomnia Narcolepsy (randomly falling sleep) Sleep Apnea (cant breath) night terrors |
|
|
Depressents |
slows down nerve system alcohol Barbiturates (tranquilizers) Opium |
|

excites nervouse system Cocaine Tobacco |
|
|
Hallucinogens |
evokes sensory inputs Marijuana LSD |
