CORRECT ANSWERS GUARANTEED 100%
SCORE RATE
"WHAT" channel - CORRECT ANSWER: S1---> S2: identification of touched objects
"WHERE" channel - CORRECT ANSWER: S1----> Parietal cortex (involved in the control of action)----> Frontal lobe (premotor cortex)
A-delta fibers - CORRECT ANSWER: myelinated nociceptors respond to heat and
pressure (quick, sharp pain)
absolute threshold - CORRECT ANSWER: the minimum intensity of stimulation that
must occur before you experience a sensation
Active exploration - CORRECT ANSWER: This (e.g. running your finger-tips over the object) allows you to differentiate between fine differences in texture (e.g. grades of sandpaper)
Ageusia - CORRECT ANSWER: inability to taste
Agnosia - CORRECT ANSWER: the inability to recognize familiar objects
Alien hand: hemisomatognosia - CORRECT ANSWER: Loss of the sense of one's own body (ex: video of the guy thinking the fake hand being hammered down is their own)
analgesia - CORRECT ANSWER: processes that act to reduce the conscious pain
experience (extreme survival)
Anarchic hand - CORRECT ANSWER: Complex goal-directed movements of a hand
that are performed against the patient's will
anosmia - CORRECT ANSWER: loss of sense of smell
Anterior Cingulate Cortex (ACC) - CORRECT ANSWER: a region of the brain
associated with emotional component of pain (unpleasant) (hypnosis studies)
anterior insular cortex - CORRECT ANSWER: Ventral, medial area of prefrontal cortex involved in facial expression and reaction of disgust
Are there really 5 senses? - CORRECT ANSWER: No, there are from 7-12 different
senses
- / 2
Aristotle and the Five senses - CORRECT ANSWER: Aristotle said there were five
senses - smell, sight, touch, taste, and hearing - but science suggests there are many more than that
backward masking - CORRECT ANSWER: Presenting a stimulus (called the target) to
the participant and then covering, or masking, the target with another stimulus
C-Fibers - CORRECT ANSWER: unmyelinated nociceptors respond to extreme heat,
cold, pressure, and toxic chemicals (throbbing pain)
Catch Trials and their use - CORRECT ANSWER: catch trials are those in which no
signal is given. The use of a catch trial may help to estimate the level at which a participant is guessing when no stimulus is present
Changes in criterion - CORRECT ANSWER: shift to left=value is smaller and the
observer will respond that the signal is present more of the time (more false alarms) shift to the right=value is larger and the observer will be less likely to respond that the signal was present
cognitive habituation - CORRECT ANSWER: The psychological process by which, after long-term exposure to an odor, one no longer has the ability to detect that odor or has very diminished detection ability.
computational approach - CORRECT ANSWER: Describes the problem the system is
trying to solve and the constraints it uses in order to solve it, most abstract
Correct Rejection - CORRECT ANSWER: signal not present, signal not detected
criterion - CORRECT ANSWER: controlled by the observer
d prime - CORRECT ANSWER: The distance between the signal and the external
noise + signal.Large d' - increasing the discriminability of signal from noise (Loud ringtone, soft music)MORE CORRECT RESPONSES Small d' - decreasing the discriminability of signal from noise (soft ringtone, loud music)
Diabetic foot - CORRECT ANSWER: Vascular damage, blood vessels don't carry blood to extremities
Differences in sensitivity (d prime) - CORRECT ANSWER: difference between the
means of the Signal Present and Signal Absent distributions
EEG (electroencephalogram) - CORRECT ANSWER: shows brain's electrical activity
by positioning electrodes over the scalp
Emotional pain - CORRECT ANSWER: no tissue damage but still feel pain
