Signal Detection
A situation where a person correctly identifies that no signal is present?
What is a Correct Rejection?
This term refers to the failure to recognize objects visually in spite of the ability to see them
Agnosia
This is the term for fixations moving from one object or location to another.
What are saccades?
These photoreceptors are most active when looking at a blue sky.
What are S-Cones?
This is the monocular depth cue that allows us to perceive an object’s size based on knowledge of its usual size.
What is a Familiar size depth cue?
An airport screener correctly detects a dangerous item in a passenger’s luggage. This is an example of a..
What is a Hit
This type of processing involves individual elements of a stimulus combined into a unified perception.
What is bottom -up processing?
These cells respond when performing a movement & when seeing someone perform the movement.
What are mirror neurons?
This theory refers to the perception of color arising from competing signals between pairs of colors.
What is the color-opponent process/theory?
This is the monocular depth cue that involves objects moving at different speeds across the retina based on their distance from the observer.
What is Motion parallax?
Provide an example of a miss.
What is e.g. "A person trying to detect a signal in a noisy environment fails to hear an actual sound."?
This term refers to an individual who cannot identify faces, but can recognize other types of objects.
Prosopagnosia
This is the effect that happens after staring at a moving object and then looking at a stationary scene and perceiving motion in the opposite direction.
What is motion aftereffect?
These photoreceptors are most active when looking at a red apple.
What are L-cones? (Long wavelength)
This is the depth cue where distant objects appear hazier and bluish due to the scattering of light in the atmosphere?"
What is Atmospheric perspective?
Provide an example of a false alarm.
e.g. "You think your phone vibrated, but there was no notification."
What is the name of the area in the temporal lobe that specializes in recognizing faces?
What is the fusiform face area (FFA)?
This area of the brain is critical for motion perception.
What is MT/V5?
These are the 3 color-opponent pairs coded by the visual system
red v green
black v white
blue v yellow
A motion depth cue that involves the relative motion of objects as an observer moves forward or backward in a scene.
What is optic flow?
What is the signal detection theory mainly concerned with?
What is sensitivity?
This part of the cortex in particular is involved in object perception
The inferior temporal cortex (IT cortex).
A rare neuropsychological disorder in which the affected individual has no perception of motion.
What is Akinetopsia? (Motion blindness)
Color deficiencies are typically caused by this.
What are genetic variations affecting cone development in the retina.
These are the three types of depth cues.
Monocular, binocular, oculomotor
