Psych Terms for Review 1

Researcher manipulates a variable; experiemental group and control group; random assignment; allows for cause and effect; ethical limitations; can't always generalize

Using one variable to predict another; NOT cause and effect; use this when there are limitations; flexibility; NO causation

No hypothesis; just gathering data; if you need background information...factual survey

A cell used to receieve and transmit information to the Central Nervous System

Cell body

branches, receieve information from neurons/sensory organs

signals sent to other neurons

protects axon and transmission of signal; like insulation

nodule at the end of an axon that connects it to dendrites; connects neuron to neuron

where terminal button intersects dendrite

Neurons have a semi-permeable membrane that allows different subtances to pass through (Sodium, Potassium, Chloride (-)) Chloride is trapped inside so the neuron has a neg charge; resting potential means charge inside is negative

Rapid change in polarity of neuron; the membrane breaks down, letting more ions in; the gates open; ligand-gated channels open and allow sodium to come in...makes charge less negative; voltage gated channels open when charge changes...result: release of neurotransmitters

(1) block breakdown ability (2) block re-uptake

(1) Block receptor sites (2) block release

network of nerves that connect CNS to rest of the nervous system

transmits nerves from sensor organis to CNS, nerves that connect CNS to voluntary muscles

connects CNS to involuntary muscles and organs (heart and stomach); regulates internal states (HR); sympathetic - fight or flight, gears you up, increases HR...etc

Part of the brainstem, keeps you alive - circulation, breathing, unconscious actions

Keeps you upright, coordination of movement

Keeps you awake - sleep and arousal

Production of voluntary movement (legs when walking); inhibition of unwanted movement

Limbic system; sensory relay, all info goes through Thalamus

Limbic system; controls autonomic nervous system (BP, HR, body temp, etc)

Limbic system; Learning and memory; helps consolidate new memories and find old ones

Limbic system; recognizes dangerous situations and responding; inputs from thalamus; output to hypothalamus (HR rises); fight of flight

thinking part of the brain; producing conscious thought and emotion; feelings, memories, etc

Left: processing language, verbal (controls right side of the body)
Right: visual, spatial

Back of the brain; processes vision

information about touch

Wernickes area - comprehension of language (if damaged, cannot create a real sentence, cannot read)

Motor cortextes - govern initiation of voluntary movement; Broca's area
