Cognitive Psychology Exam 1
If a cat casts a 5 mm image on you retina when it is 10 ft. away from you, that same cat will cast an image that is _______ mm when it is 20 ft. away.
2.5 mm
Cells A and B receive the same high levels of stimulation, but Cell A shows a lower level of activity relative to Cell B. Explanation for Cell A having lower activation is...
Cell A is being lateral inhibited by other nearby cells
Many subcortical structures, such as the hippocampus & amygdala come in group of two, why?
It has to do with lateralization
The use of geons is associated with...
The RBC model
Which methodology does not measure brain activity or structure?
Transcranial Magnetic Stimulation
Some people have sustained brain damage and lost the ability to identify color. Other people sustained damage to a different area of the brain and lost the ability to detect motion. What does this indicate about our visual system?
We have specialized areas for processing different kinds of visual information
Which of the following does NOT provide an example for parallel processing in the visual system?
You have two eyes that process different information, but work at the same time
Researchers using fMRI find activity in the FFA when participants are viewing faces. This means the FFA...
activity is correlated with recognizing faces
Brad is able to read a clock, but is unable to see the arms of a clock move from position to position. He is suffering from
akinetopsia
A central problem in Capgras Syndrome seems to be difficulty with...
an emotional analysis of faces
The primary visual cortex is located...
at the part of the cortex that is farthest from the eyes (occipital lobe)
Which of the following would NOT be considered part of the fovea? a. a cluster of cones in the center of the retina b. the area of the retina found far out in the periphery c. the region of the retina with the greatest acuity d. the are of the retina on which we place a target image in order to see the target clearly
b. the area of the retina found far out in the periphery
Human brains have a distinct division-of-labor strategy. Each task is achieved as a result of multiple brain areas working together. But the work of the various parts of the brain must be compiled into a finished whole. The issue of how this reassembly works is referred to as the
binding problem
__________ are located in the fovea, while __________ are located primarily in the periphery.
cones, rods
Despite the fact that sensory stimuli can change from moment to moment, we perceive the details of an image be stable b/c of...
constancy
A researcher has identified the receptive field for a neuron and has determined that the receptive field has a center-surround organization. If the researcher were to shine light into the entire receptive field, including both the center and the surrounding areas, we would expect the neuron to
continue firing at its resting rate
Which of the following statements about the visual stimulus, light, is FALSE? a. Light is characterized in wavelengths that vary in frequency and amplitude. b. Color (hue) is represented by the amplitude of the wavelength. c. Our visual system is only able to detect a small proportion of all of the electromagnetic spectrum. d. Red light is associated with longer waves, relative to blue light.
d. red light is associated with longer waves, relative to blue light
You are at the zoo watching a tiger sleep. It suddenly awakes and lurches in your direction. Spatial position would NOT provide information about the tiger's
dangerous nature
Cells detecting the boundary of a surface are subject to less lateral inhibition than cells detecting the center of the same surface. This leads to an effect called
edge enhancement
Parvo cells are similar to magno cells in what way?
location in the visual system
Because of its center-surround organization, a neuron that has its entire receptive field exposed to bright light will
maintain the same rate of firing as if there was no light presented.
Single-cell recordings measure the ________ of individual neurons.
pattern of firing
Patients who have suffered damage to the occipital-parietal pathway (the "where" system) will have difficulties with which of the following tasks?
reaching in the correct direction to retrieve the toothbrush
Through single-cell recordings, researchers have identified the ________ neurons in the visual system.
receptive fields of
Someone with akinetopsia would have difficulty with all of the following EXCEPT a. crossing the street b. pouring a drink c. playing pac-man d. recognizing faces
recognizing faces
The ________ is the part of the eye involved in transducing light energy into neural energy.
retina
A researcher wishes to determine exactly when a particular neuron is firing. A technique well suited to this purpose is...
single-cell recording
The importance of vision for humans is reflected in the...
the relative size of the visual cortex
Which of the following characteristics is NOT used to diagnose visual stimuli by neurons in the visual system?
the rhythm of the firing of the neuron
The specialization evident in visual processing shows that...
the visual system relies on parallel processing
Which of the following statements does NOT illustrate the difference between rods and cones? a. Rods are sensitive to lower levels of light b. only cones are able to discriminate color c. there are three types of rods and only one type of cone d. cones have greater acuity
there are three types of rods and only one type of cone
If visual info conflicts with other info, we usually...
trust visual input
