experiment - answers (IV, DV), cause-and-effect inferences
double-blind experiment - answers an experiment in which both the experimenter and
participant are withheld information that could create potential bias
single-blind experiment - answers an experiment in which the participants are withheld
information that could create potential bias
repeated measures experiment - answers an experiment used for observational studies
that take repeated measures of the same individuals over time
-goal: to compare conditions rather than groups of people
-practice: become more comfortable after 1st trial
-fatigue: concentration decreases
independent samples experiment - answers an experiment in which there is no
relationship between the measurements in the different samples
-manipulate the independent variable, otherwise equal
-all potential confounding variables cancel each other out, whatever results at the end
must have been caused by experimental manipulation
placebo - answers a fake drug used for testing; has no effect on the participant
case study - answers a descriptive technique in which one individual or group is studied
in depth in the hope of revealing universal principles
observation - answers a study where the researcher merely observes the subject
without controlling any variables
correlational - answers variables are measured and the relationship between them is
quantified
-no IV, DV
-don't know the direction of influence
quasi-experiment - answers an experiment in which the IV occurs naturally and is not
manipulated in any way (ex. age, gender, cultural background)
physiology - answers the study of how the body and its parts work or function
,informed consent - answers must be informed by the nature of the experiment and
notified they are welcome to leave at any time
voluntary participation - answers chosen to be there voluntarily
restricted use of deception - answers deception should not be used unless necessary to
the experimental design
debriefing - answers following the experiment, researchers should discuss the
experiment with the subjects
confidentiality - answers participants identity is remained confidential
no undue stress/harm - answers mental and psychological strain that could have been
avoidable
PET scan (positron emission tomography) - answers depicts brain activity by showing
each brain areas' consumption of its fuel source (glucose)
-best test for function
-useful for information on strokes
MRI (magnetic resonance imaging) - answers uses powerful magnets, radio waves, and
a computer to make detailed pictures inside your body/ brain
-highest quality of brain pictures; now shows blood flow in color (venal or arterial)
CT scan (computed tomography) - answers detailed x-ray of the brain
-used for identification purposes, not causation
fMRI (functional MRI) - answers Uses powerful magnets, radio waves, and a computer
to reveal both structure and function at the same time
- 3D image of the brain
EEG (electroencephalogram) - answers cap with leads to monitor brainwave activity
-mostly used for sleep studies, seizures
localization - answers every behavior has its specific place in the brain and is
associated with a certain brain area
Broca's Area - answers controls language expression - an area of the frontal lobe,
usually in the left hemisphere, that directs the muscle movements involved in speech
-controls facial neurons, speech, language comprehension
-expressive aphasia: trouble putting words together to form sentences
Wernicke's Area - answers Controls language reception. Damage creates inability to
comprehend language; usually in the left temporal lobe
-controls language comprehension
, -receptive aphasia: trouble understanding written language and speech
hippocampus - answers learning, memory, converting ST to LT memory
amygdala - answers memory, emotion, fear
cerebral cortex - answers temporal lobe, frontal lobe, occipital lobe, parietal lobe
temporal lobe - answers memory, speech, processing audio
frontal lobe - answers reasoning, planning, thinking, decisions
occipital lobe - answers visual processing
parietal lobe - answers movement, perception, recognition
corpus callosum - answers structure of neurons that connects the two hemispheres of
the brain
basal ganglia - answers movement
motor cortex - answers controls voluntary movements (cortical)
sensory cortex - answers area at the front of the parietal lobes - sight, sound, touch,
taste, and smell
neuroplasticity - answers the brain's ability to reorganize itself (both physically and
functionally) by forming new neural connections throughout life
neural networks - answers networks of nerve cells that integrate sensory input and
motor output
neural pathways - answers links between neurons that "wire" the brain so that the brain
can control different body functions and thinking processes
neural pruning - answers the death of redundant or unused axons
genetic / environmental influence - answers learning or injury
changes in structure / function - answers allows the neurons in the brain to compensate
for injury and disease and to adjust their activities in response to new situation or to
changes in their environment
neurotransmission - answers the process of transferring information from one neuron to
another at a synapse
