What is the Muller Lyer illusion quizlet?
muller lyer illusion is a visual illusion in which one of two lines of equal length, each of which has opposite shaped ends, is incorrectly perceived as being longer than the other.
What did Jessica Witts study test?
Witt studies how a person’s ability to act influences their perception. For example, softball players who are hitting better than others see the ball as bigger. Objects that can be reached and grasped look closer and smaller.
Which type of perceptual cue causes the Shepard tables illusion?
The MIT Encyclopedia of the Cognitive Sciences explains the illusion as an effect of “size and shape constancy [which] subjectively expand[s] the near-far dimension along the line of sight.” It classifies Shepard tables as an example of a geometrical illusion, in the category of an “illusion of size.”
Which explanation of the Müller Lyer illusion is offered by the text?
Which explanation of the Muller-lyer illusion is offered by the text? The corners in our carpentered world teach us to interpret outward- or inward-pointing arrowheads at the end of a line as a cue to the line’s distance from us and so to its length.
What is the purpose of the Müller-Lyer illusion?
Like most visual and perceptual illusions, the Müller-Lyer illusion helps neuroscientists study the way the brain and visual system perceive and interpret images. Artists have also utilized the illusion to great effect in their works.
Why is Müller-Lyer illusion?
The Conflicting Cues Explanation Day suggests that the Muller-Lyer illusion occurs because of conflicting cues. Our ability to perceive the length of the lines depends on the actual length of the line itself and the overall length of the figure.
Which was the dependent variable in Jessica Witt’s study quizlet?
This study had two dependent variables: (a) the size of the circle drawn by the participant.
What happened when the participants were asked to draw the size of the hole in Jessica Witts research?
We found that judged hole size was negatively correlated with the players’ performance that day. Players who played better judged the hole to be bigger. This finding is consistent with our early finding that softball players who are batting better judge the ball as being bigger (Witt & Proffitt, 2005).
Is convergence monocular or binocular?
The physiological depth cues are accommodation, convergence, binocular parallax, and monocular movement parallax. Convergence and binocular parallax are the only binocular depth cues, all others are monocular.
Why does Müller-Lyer illusion?
Day suggests that the Muller-Lyer illusion occurs because of conflicting cues. Our ability to perceive the length of the lines depends on the actual length of the line itself and the overall length of the figure.
