PSYC 230 UIUC REVISION TEST 2025 QUESTIONS WITH
ANSWERS GUARANTEE A+
✔✔The Opponent Theory of Color Perception - ✔✔Hering's model of opponent
processes- red, green, blue, yellow = 4 colors
✔✔Rod Monochromacy - ✔✔severe impairments of vision
✔✔Cone Monochromacy - ✔✔problem lies in the cone system
✔✔Dichromacy - ✔✔missing red/green (everyone can see blue)
✔✔Tritanopia - ✔✔S cone system is absent; lack green and yellow
✔✔Protanopia - ✔✔L cone system is absent; lack green and red
✔✔Deuteranopia - ✔✔M cone system is absent; lack green and red
✔✔Cortical Achromatopsia - ✔✔loss of color vision due to damage to occipital lobe
✔✔Constancy - ✔✔the ability to perceive an object as the same object under different
conditions
✔✔Color Constancy - ✔✔the ability to perceive the color of an object despite changes
in illumination
✔✔Synesthesia - ✔✔accidental association of 2 percepts with 1 perception eliciting a
secondary perception (2 or more).
✔✔Real Motion - ✔✔the motion in the world created by continual change in the position
of an object relative to the frame of reference
✔✔Apparent Motion - ✔✔sequence of still images
✔✔The Correspondence Problem - ✔✔how is motion processed in the brain
✔✔Corollary Discharge Theory - ✔✔the motor system tells the eyes to move AND
sends a copy to the brain
✔✔Saccades - ✔✔fast eye movements
✔✔The Movement Area of the Brain - occipital lobe in the dorsal pathway, specific to
motion detection and perception - ✔✔
, ✔✔Akinetopsia - ✔✔motion blindness
✔✔Affordance - ✔✔the information in the visual world that specifies how that
information can be used
✔✔Optic Flow - ✔✔as we move, the objects present in the environment start moving on
our retinas
✔✔The Focus of Expansion (when moving forward) - ✔✔the only point that is not
moving is the point we are fixating
✔✔Lateral Intraparietal (LIP) Area - ✔✔how we compute eye movement
✔✔Relative Height - ✔✔objects closer to the horizon are seen as more distant
✔✔Relative Size - ✔✔the more distant the object, the smaller the image will be on the
retina
✔✔Familiar Size - ✔✔we judge distance based on existing knowledge of the sizes of
objects
✔✔Linear Perspective - ✔✔the pictorial depth cue that arises from the fact that parallel
lines appear to converge as they recede in the distance
✔✔Texture Gradients - ✔✔textures become finer as they recede in the distance
✔✔Atmospheric Perspective - ✔✔objects in the distance appear blurred and tinged with
blue
✔✔Shadows and Shading - ✔✔an object in front of its shadow and the angle of the
shadow can provide some information about how far the object is in front of the
background
✔✔Motion Parallax - ✔✔a cue that arises from the motion of a person in the
environment. Faster moving objects are closer to us; slower moving objects are farther
away
✔✔Deletion - ✔✔the gradual occlusion of a moving object as It passes behind another
✔✔Accretion - ✔✔the gradual reappearance of a moving object as it emerges from
behind another object
✔✔Optic Flow - ✔✔the motion depth cue that refers to the relative motions of objects as
a person moves forward or backward
