PSYCH 333 EXAM 1 – Psychology course exam material
What are sensation and perception? - correct answer ✔✔Sensation: the process of
transforming physical stimuli to electrical (neuronal) signals
Perception: the process of interpreting these signals for conscious awareness.
The smallest amount of a stimulus that is detectable is called [ ]. - correct answer ✔✔Absolute
threshold
The relationship between the size of a just detectable difference and the initial magnitude of a
stimulus is called the [ ]. - correct answer ✔✔Weber Fraction
[ ] is based on the assumption that the perceptual magnitude of a just noticeable difference is a
constant. - correct answer ✔✔Fechner's Law
Different types of electromagnetic radiation, including visible light, are distinguished from each
other by their differences in [ ]. - correct answer ✔✔Wavelength
Light is most often specified in [ ], units that represent a billionth of a meter. - correct answer
✔✔nanometer
The position of the eyes on the head of an animal determines the tradeoff between the region
of stereo depth perception and the overall [ ]. - correct answer ✔✔Visual field
The arrangement of neurons such that adjacent neurons in visual areas such as LGN and V1
have adjacent receptive fields and receive signals from retinal ganglion cells that also have
adjacent receptive fields is called [ ]. - correct answer ✔✔Retinotopic mapping
, The first synapses after the retina along the path to primary visual cortex are found in [ ] -
correct answer ✔✔Lateral Geniculate Nucleus (LGN)
The left LGN receives input from [ ]. - correct answer ✔✔Left Temporal retina and Right nasal
retina
LGN has [ ] layers. - correct answer ✔✔6
LGN's Layer 3-6 are [ ] layers. - correct answer ✔✔Parvocellular
LGN's Layer 1-2 are [ ] layers - correct answer ✔✔Magnocellular
Things that is between LGN's layers are [ ] layers. - correct answer ✔✔Koniocellular
Visual signals from Ipsilateral eyes goes [ ] layers of LGN. - correct answer ✔✔2,3,and 5
Visual signals from contralateral eyes goes [ ] layers of LGN. - correct answer ✔✔1,4,and 6
The [ ] layers of the LGN receive input primarily from midget ganglion cells, which give
information about [ ]. - correct answer ✔✔Parvocellular, color, form, and stereo vision.
The [ ] layers of the LGN receive input primarily from parasol ganglion cells, which give
information about [ ]. - correct answer ✔✔Magnocellular, and motion
The [ ] layers of the LGN receive input primarily from small-bistratified ganglion cells, which give
information about [ ]. - correct answer ✔✔Koniocellular,and color
