Perception

________: process of interpreting stimuli sensory information processing.

sensation vs perception sensation

process of experiencing stimuli

perception

process of interpreting stimuli sensory information processing

sensation

the process of experiencing stimuli

perception

the process of interpreting stimuli

sensory store characteristics

verdical form, relatively large, and lasts for only a brief period of time

iconic memory

the brief storage of visual information

how long does iconic memory last?

250 milliseconds

echoic memory

the auditory sensory memory

how long does echoic memory last?

3-4 seconds

afterimage

an image that continues to appear in the eyes/memory after being exposed to the original image

how do iconic memory and an afterimages differ when it comes to colors?

afterimages are the opposite colors as the original image. iconic memory members the original colors

how do iconic memory and afterimages differ when it comes to whether the image is presented to one eye or not?

afterimages can occur even if only one eye is shown the image. iconic memory only occurs if both eyes see the image.

what was Sperling's test?

Sperling tested iconic memory by showing subjects 12 letters in 3 rows for 50 milliseconds and asking them to recall one row. this showed that iconic memory lasts for up to 250 milliseconds

what was the 3-eared man experiment?

the 3-eared man experiment had subjects hear 3 letters given to them in the left ear, 3 letters given to them in the right ear, and 3 letters given to them in both ears (at the same time). they were then asked to recall one ear's letters. this showed that echoic memory lasts for 3-4 seconds.
