Flashcards in Ch 5 Deck (10):
1

Compare and contrast sensation and preception

-Sensation:activation of neural receptors by environmental stimuli---> immediate stimulation
-Perception:organization and interpretation of those stimuli--->meaning based.

2

What is meant by bottom-up and top-down processing?

-Bottom-up: taking in sensory information to build perceptions
-top-down:how we interpret those sensations is influenced by our available knowledge, our experiences, and our thoughts. using models, ideas, and expectations to interpret sensory information

3

Explain the conditions of synesthesia

-synesthesia: stimulation of one sensory pathway leads to automatic experiences n another pathway. ex every number you see has a specific color it has.

4

Compare and contrast absolute thresholds with difference thresholds.

-Absolute thresholds: minimum level of stimulus intensity needed to detect a stimulus
-Difference thresholds: how much difference in stimuli is required to detect a difference between them.

5

explain subliminal processing

-Messages that are perceived outside the conscious awareness(outside awareness). ex billboards

6

explain sensory adaptation

-when we become less responsive to unchanging stimuli. ex, having a cell phone in your pocket.

7

What is transduction?

Converts physical stimuli into nerve impulses
ex. light waves converted into nerve impulses in retina.
sound waves into nerve impulses in cochlea.

8

how does transduction occur in the ear?

-outer ear directs air vibrations--> bone & hair movement in inner ear-->nerve impulses

9

What are some examples of perception?

-organizing words into music
-interpreting words for meaning

10

What are the factors that influence perceptual interpretation

-context
-expectation
-experience
