Chapter 6 Percpetion Flashcards
Percpetion
the process of selecting, organizing, and interpreting sensory information
The Cocktail Party Effect
a type of selective listening where we filter out noise and focus on one conversation
Inattentional Blindness
the inability to see an object or person in our midst
Change Blindness
a form of inattentional blindness where individuals giving directions failed to notice a change in the individual asking for directions
Perceptual Illusions
help us understand how perception is organized, the context matters
Visual Capture
vision wins when competing with other senses
Form Perception
Organization of the visual field into figures that stand out from their ground
Grouping
Proximity, Similarity, Continuity, Connectedness, Closure (can lead us astray)
Depth Perception (Visual Cliff)
Allows us to judge distances
Binocular Cues
Things seen using two eyes (Retinal Disparity, Convergence)
Retinal Disparity
Images from the two eyes differ
Convergence
Two eyes move inward to see near objects, outward to see far objects
Monocular Cues
Can be seen using one eye (Relative Size, Interposition, Relative Clarity, Texture Gradient, Relative Height, Relative Motion, Linear Perspective, Light and Shadow, Motion Perception)
Relative Size
When two objects are similar size, we perceive that one casts a similar image farther away
Interposition
Objects that block other objects are perceived as closer
Relative Clarity
We perceive hazy objects to be farther away than those that apear clear
