investigates distractions and interferences we experience as we perceive the world

Q

False +

A

when we think we perceive a stimulus that is not really there

58
Q

False -

A

not perceiving a stimulus when it is present.

top-down processing

A

we perceive by filling in the gaps we sense

60
Q

schemata

mental representations of how we expect the world

perceive something in a certain way

61
Q

bottom-up processing

A

use only features of the object itself to build a complete perception

62
Q

Extra Sensory perception

A

belief that one can have perceptual experience without any sensory input
