29
Scientific method
- description - observing/noting everything down - explanation - trying to understand findings + creating theory - prediction - determining what will happen in the future - control - modification of behavior
30
Gustav Fechner
credited for performing first scientific experiments that formed a basis for psychological experimentation
31
Wilhelm Wundt
objective introspection - process of objectively examining and measuring one's own thoughts and mental activities
32
William James
functionalism - how people work, play, and adapt to their surroundings
33
Max Wertheimer
gestalt - studying sensation and perception with focus on whole patterns
34
Sigmund Freud
psychoanalysis - unconscious/unaware mind in which people repress urges and desires (thought repressed urges/desires created nervous disorders)
35
John B. Watson
behaviorism - human behavior can be understood by examining the relationship between events in the environment and observable behavior
36
Carl Rogers
humanistic - humans are free agents capable of controlling their own lives, making their own choices, setting goals and working to achieve them (humans are inherently good)
37
Edward Titchener
structuralism - everything can be broken down into individual emotions and sensations
38
Margaret F. Washburn
first woman to receive a PhD in psychology
39
Mary Whiton Calkins
earliest research in human memory and psychology of self; never earned PhD because she was a woman
40
G. Stanley Hall
founder and first president of the American Psychological Association
41
Industrial/organizational psychology
application of psychological concepts to businesses, organizations, and industry
42
Ivan Pavlov
proved that a reflex could occur in response to a formerly unrelated stimulus (Pavlov's dogs)
43
Mary Cover Jones
early pioneer of behavior therapy
44
Operant conditioning
created by B.F. Skinner; behavioral responses followed by pleasurable consequences are strengthened/reinforced
45
Nervous system
network of cells that carries info throughout the body
46
Santiago Ramon y Cajal
first theorized that nervous system was made up of individual cells
47
Neuron
cell in nervous system that receives/sends messages throughout the system
48
Glial cells
supports neurons (structurally, giving nutrients...)
49
Schwan cells
generates fatty layer of myelin for PNS; myelin can serve as tunnel if nerve cell is damaged, and can repair/reconnect neuron
50
Oligodendrocytes
generates fatty layer of myelin for CNS
51
Tracts
myelin-coated axons in CNS
52
Nerves
myelin-coated axons in PNS
53
Myelin sheath
insulates and protects neuron; allows electrical signal to be sent faster
54
Sodium potassium pump
salty banana
55
Resting potential
when sodium potassium pump is at rest
56
Action potential
neural impulse that carries info along the axon of a neuron; the action potential is generated when positively charged ions move in and out through the channels in the axon membrane
57
Toilet metaphor
all or nothing threshold refractory period
58
Major neurotransmitters
acetylcholine (ACh) - excitatory; stimulates muscle contractions dopamine (DA) - excitatory or inhibitory; pleasure serotonin - excitatory or inhibitory; associated with sleep, mood, anxiety, appetite glutamate - excitatory; learning and memory gamma-aminobutyric acid (GABA) - inhibitory endorphins - inhibitory; lessens pain by inhibiting pain signal epinephrine - excitatory; adrenaline norepinephrine (NE) - excitatory; stress hormone
59
Threshold of excitation
threshold to reach in order for message to fire throughout neuron (majority rules - if enough excitatory neurotransmitters over inhibitory neurotransmitters)
60
Antagonist
blocks/reduces effects of neurotransmitter
61
Agonist
mimics/enhances effects of neurotransmitter
62
Peripheral nervous system (PNS)
includes all nerves and neurons not in brain and spinal cord; made up of somatic nervous system (controls voluntary muscles; made up of sensory and motor pathways) and autonomic nervous system (controls involuntary muscles, organs, and glands; middle of spinal cord is sympathetic - fight or flight; top and bottom of spinal cord is parasympathetic - eat, drink, rest)
63
3 types of neurons
afferent/sensory (messages from senses to spinal cord); efferent/motor (messages from spinal cord to muscles and glands); interneurons (connects afferent neurons to motor neurons) Afferent neurons Access the spinal cord, Efferent neurons Exit
64
Neuroplasticity
ability to constantly change both structure and function of cells in brain in response to experience or trauma
65
Endocrine glands
controlled by pituitary gland; secrete chemicals/hormones directly into bloodstream unlike salivary or sweat glands which secrete chemicals/hormones into body's tissues
66
Positron emission tomography (PET)
lets researchers see what areas of the brain are most active during certain tasks; PET scan measures how much of a certain chemical parts of the brain are using (more chemical = more activity)
