False
If the Interstimulus Interval between frames in a cartoon is too long…
Consecutive frames will be perceived one at a time, but without motion
Why do Elementary (Reichardt) Motion Detectors need 2 photoreceptor inputs?
To respond if a feature moves a certain distance over a specific time
Which visual motion area has the largest receptive fields?
MST
All motion in the aperture problem is seen as moving _______ to the elongated contour/edge.
Perpendicular
According to the Corollary Discharge theory, motion is perceived when the Comparator is…
Unbalanced
Mixing blue and yellow ____ will produce green, but mixing blue and yellow ____ will produce white.
paint // light
What was the major finding of the spatial attention pre-cuing task?
Valid ques decrease reaction time.
Which statement is true about visual search according to Anne Treisman’s feature integration theory?
Conjunction search will usually take longer the more distractors there are.
When a subject views an image for the first time, what determines where they will saccade to first?
They will saccade to salient features first.
Which type of person with color vision deficiency has the highest neutral point?
A person with Tritanopia.
What question best captures the essence of the binding problem?
How are individual features combined to create perception of a coherent object?
In Anne Treisman’s feature integration theory, which stages have parallel vs. serial information processing?
Preattentive stage is parallel; Focused attention stage is serial.
How is the “Y-“ created in a B+Y- single opponent color sensitive neuron?
The B+Y- neuron receives inhibition from both M and L cones.
Pick the answer that best describes the way a green apple interacts with white light.
The green apple absorbs shorter and longer wavelengths and reflects medium wavelengths.
What information would be most important for you to locate the border of a painted square on the outside wall of a building?
The reflectance edges of the square created by the paint’s pigment.
True or False: Perception of biological motion is impaired following damage to area MST.
False
Jona is standing closer to you than Sean. From your perspective, as you side-step to the left you notice that your view of Jona blocks your view of Sean. Which statement describes depth cues that tell you who is closer?
Jona deletes Sean
Which theory for the Muller-Lyer illusion uses the contours produced by the inside and outside corners of rooms as part of its explanation?
The misapplied size constancy scaling theory.
You are fixating on Sam. Timmy starts walking towards you, starting farther away than Sam, then passing beside Sam, finally ending up closer to you than Sam. Which statement describes the binocular disparity of Timmy during his journey?
Timmy starts in uncrossed disparity and finishes in crossed disparity.
Kaylee is viewing a horizontal stripe through a small porthole. The stripe is moving at -45 degrees (i.e. down and to the right). What direction will Kaylee perceive the motion?
straight down

occlusion
You have created a computer simulation of an elementary motion detector. If you set the delay to a large value, the motion detector will respond best to…
slow motion
Shauna is on a ZOOM call using slow WiFi. Instead of smooth motion, she perceives individual video frames presented one after the other, but each one appears stationary. What is the problem with this apparent motion stimulus?
The interstimulus interval is too long.
Why would a person perceive motion when pushing gently on their eyeball while fixating on a stationary spot?
The pushing causes the eye muscles to contract to maintain fixation, but no retinal image motion.
“__________ perception” refers to perception that matches the actual physical stimulus.
Veridical
