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
