29
Q

Scientific method

A
  • 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
Q

Gustav Fechner

A

credited for performing first scientific experiments that formed a basis for psychological experimentation

31
Q

Wilhelm Wundt

A

objective introspection - process of objectively examining and measuring one’s own thoughts and mental activities

32
Q

William James

A

functionalism - how people work, play, and adapt to their surroundings

33
Q

Max Wertheimer

A

gestalt - studying sensation and perception with focus on whole patterns

34
Q

Sigmund Freud

A

psychoanalysis - unconscious/unaware mind in which people repress urges and desires (thought repressed urges/desires created nervous disorders)

35
Q

John B. Watson

A

behaviorism - human behavior can be understood by examining the relationship between events in the environment and observable behavior

36
Q

Carl Rogers

A

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
Q

Edward Titchener

A

structuralism - everything can be broken down into individual emotions and sensations

38
Q

Margaret F. Washburn

A

first woman to receive a PhD in psychology

39
Q

Mary Whiton Calkins

A

earliest research in human memory and psychology of self; never earned PhD because she was a woman

40
Q

G. Stanley Hall

A

founder and first president of the American Psychological Association

41
Q

Industrial/organizational psychology

A

application of psychological concepts to businesses, organizations, and industry

42
Q

Ivan Pavlov

A

proved that a reflex could occur in response to a formerly unrelated stimulus (Pavlov’s dogs)

43
Q

Mary Cover Jones

A

early pioneer of behavior therapy

44
Q

Operant conditioning

A

created by B.F. Skinner; behavioral responses followed by pleasurable consequences are strengthened/reinforced

45
Q

Nervous system

A

network of cells that carries info throughout the body

46
Q

Santiago Ramon y Cajal

A

first theorized that nervous system was made up of individual cells

47
Q

Neuron

A

cell in nervous system that receives/sends messages throughout the system

48
Q

Glial cells

A

supports neurons (structurally, giving nutrients…)

49
Q

Schwan cells

A

generates fatty layer of myelin for PNS; myelin can serve as tunnel if nerve cell is damaged, and can repair/reconnect neuron

50
Q

Oligodendrocytes

A

generates fatty layer of myelin for CNS

51
Q

Tracts

A

myelin-coated axons in CNS

52
Q

Nerves

A

myelin-coated axons in PNS

53
Q

Myelin sheath

A

insulates and protects neuron; allows electrical signal to be sent faster

54
Q

Sodium potassium pump

A

salty banana

55
Q

Resting potential

A

when sodium potassium pump is at rest

56
Q

Action potential

A

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
Q

Toilet metaphor

A

all or nothing
threshold
refractory period

58
Q

Major neurotransmitters

A

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
Q

Threshold of excitation

A

threshold to reach in order for message to fire throughout neuron (majority rules - if enough excitatory neurotransmitters over inhibitory neurotransmitters)

60
Q

Antagonist

A

blocks/reduces effects of neurotransmitter

61
Q

Agonist

A

mimics/enhances effects of neurotransmitter

62
Q

Peripheral nervous system (PNS)

A

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
Q

3 types of neurons

A

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
Q

Neuroplasticity

A

ability to constantly change both structure and function of cells in brain in response to experience or trauma

65
Q

Endocrine glands

A

controlled by pituitary gland; secrete chemicals/hormones directly into bloodstream unlike salivary or sweat glands which secrete chemicals/hormones into body’s tissues

66
Q

Positron emission tomography (PET)

A

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)
