Key Perspective 1 - correct answer ✔✔Sensory receptors selectively sample the world
Key Perspective 2 - correct answer ✔✔More is sensed than what is perceived
(illusion: shoe example, basketball with gorilla example)
Key Perspective 3 - correct answer ✔✔Perception is more than what is sensed
(illusion: stereo vision, illusory contour, illusory motion, neon corners, grid illusion)
Key Perspective 4 - correct answer ✔✔Perceptions are the brain's inferences about the world
(illusion: light from above heuristic, borders changing color of objects, table changing size)
Key Perspective 5 - correct answer ✔✔Brain's rules for creating perceptions have been shaped
by what's been adaptive over the course of evolution
(illusion: railroad line example, tiger example)
Key Perspective 6 - correct answer ✔✔The role of sensation and perception is to sample
information from the world to create efficient representations of the world
(illusion: Necker cube, is it coming towards or going away?, spinning lady, image of two people
or vase)
Sensation - correct answer ✔✔The process of transforming physical stimuli to neural signals
Perception - correct answer ✔✔Using information gathered from neural signals from sensation
to create an idea of what is going on
