Environmental Stimuli
|
What stimuli is out there in the environment.
|
|
Attended Stimuli
|
What an organism is paying attention to.
|
|
Stimulus on the receptors
|
The image on the recepetors. Photoreceptors = Vision. Macanoreceptors = Touch. Hair Cells = Audio. Chemoreceptors = Smell and Taste.
|
|
Transduction
|
The process through which an image on the retina is turned into a nerve impulse.
|
|
Neural processing
|
A map of the physical representation of the areas of the brain where info is combined and analyzed.
|
|
Perception
|
Conscious awareness of what is out there in the world.
|
|
Bottom-Up Processing
|
This is data driven processing that starts small and builds up.
|
|
Top-Down Processing
|
This is knowledge based processing where past knowledge influences perception.
|
|
What are the levels of analysis of perceptional infromation?
|
The Psychophysical Level.
The Stimulus-Physiolgocial Relationship.
The Physiolgoy-Perception Relationship.
|
|
The Psychophysical Level.
|
Qualitative methods that measure what a person perceives. This is the first step in studying perception, and is referend to as a phenomenological method.
|
|
The Stimulus-Physiolgocial Relationship.
|
Maps the relationship between the physiolgocial experience and the nervous system.
|
|
The Physiolgoy-Perception Relationship.
|
Maps the relationship between the physiological experience and the perceptual experience.
|
|
Absolute Threshold
|
The smallest amount of stimulus that is required to be able to barely detect it.
|
|
Method of Limits
|
Presentation of different intensities, at highs and lows for perception. The threshold, for the highs and the lows, is the average of the trials.
|
|
Mthod of Adjustment
|
The intensity is adjusted continuously until it is detected. The threshold is an average of the trials.
