A
it is based on one specific individual; not replicable in lab. EX Child kept in basement.
8
Q
what is a naturalistic observation
A
Observing and recording behavior in naturally occurring situations w/o trying to manipulate the control.EX Watching Chimpanzees adjust to the life in captivity.
9
Q
tell why case studies don’t allow us to test broad, general principles
A
Case studies are based on one person’s personal evaluation.
10
Q
describe wording effects and tell which type of research is most vulnerable to them
A
Wording effects are way to rephrase wordings in order to make them more appeasing. Two phrases that mean the same thing just worded differently. Description Research; Surveys
11
Q
define random sample
A
Random sample- fairly represents a pop because each has and an equal chance of inclusion
12
Q
define sampling bias
A
not representative of population. EX only ppl from psych majors
13
Q
explain what a correlation coefficient tells about two variables
A
how strongly related they are
14
Q
explain what the sign (+ or -) means in a correlation coefficient
A
It says whether it is a positive or negative correlation
15
Q
give an example of a positive correlation

the more you study the better grades you receive
16
Q
EX of negative correlation
A
The more candy you eat the worse off your teeth will be
17
Q
give the range of values that a correlation coefficient can have
A
Range: +1.00- -1.00
18
Q
ell whether .35 or -.40 indicates a stronger relationship between two variables
A
; -40 has the stronger correlation because its absolute value is larger
19
Q
give an example of a correctional study
A
The people who watch violence on TV will be more aggressive
20
Q
why is it that correlation does not imply causation
A
It only permits prediction because there could also another factor
21
Q

52
describe the basic focus of each of the following approaches and give an example of how a psychologist using that approach would explain why some people develop phobias while others do not:behavioral
focus on environmental determinants; external stimuli trigger fear
53
describe the basic focus of each of the following approaches and give an example of how a psychologist using that approach would explain why some people develop phobias while others do not:cognitive
focus on mental processes; learned, emotional
54
define the testing effect
enhanced memory after retrieving, rather than simply reading, information
55
tell why testing yourself is part of successful learning
actively process, better with exercise
56
list and define the steps in the SQ3R method of studying
Survey; survey titles headings, bird’s eye view, Question; try to answer LO’s before reading, Read; actively read and think critically, take notes, don’t tire, Retrieve; retrieve main ideas, Review; go over notes and glance over module

64
describe the characteristics of critical thinking
asking questions examines assumptions, discerns hidden values, evaluates evidence, and assesses conclusions
65
tell whether it is often the case that findings from laboratory studies have "real-world" relevance, and why
Psychological science focuses less on particular behaviors than on seeking general principles that help explain many behaviors.
66
tell whether (a) specific attitudes and behaviors, and (b) underlying processes vary by gender and across cultures
Even when specific attitudes and behaviors vary by gender or across cultures, as they often do, the underlying processes are much the same.
67
tell how humans are protected in experiments
1) obtain potential participants’ informed consent, protect them from harm and discomfort, keep information about individual participants confidential.fully debrief people (explain the research afterward)
68
explain why it's important to study biology in psychology
because knowing what is going on in the nervous system helps us explain behavior/mental processes we see
69
tell whether Plato or Aristotle first determined that the mind comes from the head (brain), rather than from the heart
Plato
70
explain what important brain phenomenon was highlighted by phrenology, despite the fact that phrenology itself was ultimately discredited
studying bumps on the skull, could reveal a person’s mental abilities and character traits.different parts of the brain are used for different things
71
receptors
where neurotransmitters are taken in A SPECIALIZED CELL THAT RESPONDS TO A PARTICULAR KIND OF ENERGY,
72
sensory neurons
carry messages from the body’s tissues and sensory receptors inward to the brain and spinal cord for processing
73
interneurons
Between the sensory input and motor output, information is processed in the brain’s internal communication system
74
motor neurons
carry instructions from the central nervous system out to the body
75
neuron structures in order to form neural pathway
Dendrites-axon-axon terminal-synaptic gap
76
dendrites
a neuron’s bushy, branching extensions that receive messages and conduct impulses toward the cell body
77
cell body
cell’s life support
78
axon
the neuron extension that passes messages through its branches to other neurons or to muscles or glands,
79
myelin sheath
a fatty tissue layer segmentally encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one node to the next
80
terminal buttons
forms junctions with other cells
81
synaptic gap
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
82
explain whether communication within a neuron or between neurons is faster, and why
Within because you don’t have to go through synaptic gaps
83
neuron at resting potential (where are potasium ions, sodium ions. and what charge does it have)
potassium:inside; sodium-outside; negative charge
84
neuron firing (where are potasium ions, sodium ions. and what charge does it have)
potasium inside; sodium-outside, neutral then positive
85
explain what the refractory period is and when it occurs; describe what the sodium pump does
it is when the cell is resetting itself; after firing; sodium gets pumped outside
86
describe the all-or-none law of neural firing and explain the concept of a threshold
The neuron must get enough excitatory signals to fire, they must reach a certain level or it will not fire (cant halfway fire a gun). A threshold is the point where enough excitatory signals set off the neuron
87
tell what endorphins are and what they do
a hormone that give energy and help with pain control
88
agonists
neurotransmitter that is similar enough to a hormone that it can mimic it.
89
antagonists
will decrease the production of a hormone
90
chart of the nervous system's organization

91
the 2 main structures of the central nervous system
brain and spinal cord
92
tell what the somatic (or skeletal) division of the peripheral nervous system does
it controls the voluntary muscle movements
93
name the two subdivisions of the autonomic nervous system and describe their opposing functions
sympathetic- arousing parasympathetic-calming
94
list 4 ways scientists can read your braain
EEG, MRI, PET, fMRI
95
EEG
reads brain waves
96
MRI
strong magnet disorients atoms then align, signals produce soft tissue images

endocrine system
the body’s “slow” chemical communication system; a set of glands that secrete hormones into the bloodstream
109
adrenal glands
secrete hormones (epinephrine and norepi-nephrine) that help arouse the body in times of stress
110
pituitary gland
regulates growth and controls other endocrine glands
111
explain why the cerebral cortex of a human is so wrinkled, compared to that of lower mammals
it has more surface area because we can function more
112

117
sensory cortex
area at the front of the parietal lobes that registers and processes body touch and movement sensations
118
association cortex
areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking
119

124
explain what functions are commonly associated with left hemisphere
speaks, calulates
125
explain what functions are commonly associated with right hemisphere
perceptual- making inferences, modulate speech for clarity, orchestrate sense of self
126
describe plasticity
the brain’s ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
127
explain how the split-brain operation has helped us determine the functions of the left and right hemispheres
