Unit 4 Sensation & Perception Flashcards
What do you call when you’re taking in information from the outside world to the brain using sense receptors?
Sensation
The way the brain organizes incoming information
Perception
Parts of the sense organs that translate the info from the outside world to neural impulses
Sense receptors
What’s The process that “translates” the outside info into “neural impulses”
Transduction
When sensory receptors are attuned to changes because of?
Sensory Adaptation
An effect which we pay attention to our “names”
Cocktail Party Effect
We can’t see because “we’re focused on something else”
Inattentional Blindness
When we don’t notice when things change
Change Blindness
defined as “the study of the relationship between sensation and perception”
Psychophysics
What are the 2 kinds of thresholds?
Absolute threshold & Difference Threshold
Explain “Weber’s law”
2 stimuli must differ by “constant minimum percentage”
It’s the “lowest amount of physical stimulus” that you can detect (50%)
Absolute threshold
Explain Different threshold
It follows Weber’s law, the percentage difference between 2 stimuli
this affects the “attitude” NOT behavior
Subminimal sensations
explain bottoms-up processing
basically sensation-perception, outside stimuli then transduced into neural impulses
