25
Recognition by components theory
recognize objects by breaking them down into simpler shapes
26
geons
set of 36 basic three dimensional shapes from which all real-world objects can be constructed
27
context effects
change in perception of a visual component of a scene based on the surrounding info in the scene + observer’s prior knowledge (ex. if someone says coffe is bitter you will think its bitter)
28
context effects (3 examples)
1.jumbled word effect. 2. empirical theory of color vision. 3. food preference
29
early selection theory
(hypothesis) attention prevents early perceptual processing of distractors
30
what happened in the dichotic listening task?
a subject would be given a message, and would have to listen to 2 streams of voices playing at the same time, and they would have to pick which stream said the needed phrase
31
dichotic listening task end result
can only process/pay attention to one stream of information at a time (not 2)
32
late selection theory (hypothesis)
hypothesis, perceive relevant/ irrelevant stimuli at the same time, must ignore irrelevant stimuli to focus on relevant ones
33
Prosopagnosia
unable to recognize faces (due to damage in FFA)
34
split brain
subject lives like they have 2 different brains (caused by the corpus callosum severing)
35
wenickes aphasia
inability to understand speech (due to damage on wernickes area)
36
brocas aphasia
inability to produce speech (due to damage to brocas area)
37
brocas area
in charge of language production
38
limits of neuroscience (2)
Neuroscience techniques are not independent and can (and should) be combined in order to learn even more about the brain • Combining techniques can be beneficial and offer more information than employing only one technique
39
interactionism
belief that the mind and brain are SEPARATE, but impact and influence eachother
40
Epiphenomenalism:
mental states or events are caused by physical states or events in the brain but do not themselves cause anything.
41
stroop task
(late selection hypothesis) say color of word not the word written
42
the stroop task proves that
humans have difficulty paying attention to two things at once
43
flicker paradigm
subject is exposed to two slighty different images between fast flickers (will they notice the difference?
44
the flicker paradigm was used to investigate
change blindness
45
change blindness
when there is a subtle change that occurs and the subject fails to notice that
46
parallelism
mind + brain = 2 aspects of reality, operate in parallel
47
isomorphism
view that mental events +neural events share the same structure
48
animal studies
49
MRI
magnetic resonance image (produces images of brain, shows brain activity)
50
ERP
Event related potentials (electrical signal emitted from the brain after the onset of a stimulus)
51
PET
Positron emission tomography (brain imaging technique, subject is injected with a radioactive substance, circulates to brain and mixes with blood
52
fMRI
Functional magnetic resonance imaging( non-radioactive magnetic procedure, detects flow of oxygenated blood to parts of brain
53
MEG
Magnetoencephalography (noninvasive brain imaging technique, directly measures neural activity
54
DTI
Diffusion tensor imaging (MRI-based neuroimaging technique, helps visualize the white-matter tracts in brain
55
sustained attention to response task
SART (continuous response task in which digits (O to 9) are sequentially presented on a computer screen and participants are asked to press a button in response to all but one of them (e.g., just the number 3)
56
comission errors
failure to withhold a response)
57
attentional blink
fail to notice the second of two stimuli presented within 550 milliseconds of each other
58
commission error in sustained attention to response task
used as a measure of attentional lapses in this task
59
jumbled word effect
can still read sentences even if letters are mixed up
60
empirical theory of color vision
theory, color perception is impacted by one's experiences
