CHAPTER 8: Percieving Motion Flashcards
What is perceptual completion? Which of the following is an example of perceptual completion?
A) Grouping similar shapes together
B) Separating figures from the background
C) Recognizing a familiar face
D) Filling in the gaps between letters in a word
Perceptual completion: a cognitive process by which the brain fills in gaps in visual information to create cohesive and comprehensive image or perception.
D) Filling in gaps between letters in a word
What is the Ponzo illusion and what does it demonstrate?
The Ponzo illusion is an image that features two animals on a railroad track, and one appears longer than the other despite them being the same size. The illusion demonstrates the influence of depth perception
What is the parvocellular pathway, and what is it’s primary function in visual processing?
the parvocellular pathway carries information about small, slow colourful things. It has high spatial frequency and low temporal temporal frequency.
It’s primary function is processing colour and fine details
how does colour perception influence object and face recognition?
colour perception helps object and face recognition by providing visual cues
describe Newton’s prism experiment and its contribution to understanding colour perception
Newton’s prism experiment demonstrated the visible spectrum by splitting white light and that the colour we see is the remainder of the white light that is being reflected from the object.
what is the role of the fusiform face area and how does it contribute to face perception and recognition? How is it specialized?
The role of the fusiform face area specializes in face processing, showing increased activity during facial feature analysis and familiar face recognition
explain the difference between apparent movement, illusory motion, biological motion, implied motion, induced motion, and real motion
apparent movement: an illusion of movement that occurs when two objects separated in space are presented rapidly, one after another, separated by a brief time interval.
illusory movement: similar to apparent motion - perception of motion when there is actually none
biological motion: motion produced by biological organism (point-light walkers)
implied motion: when a still picture depicts an action that involved motion so that the observer can picture in their mind what would likely occur next
induced motion: the illusory movement of one object that is caused by the movement of another object that is nearby
real motion: the physical movement of a stimulus (constrasts with apparent motion)
