Term
| what is phantom limb pain |
|
Definition
| alarming, puzzling pain in amputated limb, sensory receptors are gone but brain and nerves that received are confused |
|
|
Term
| this is the minimum amount of stimulus energy that a person can detect |
|
Definition
|
|
Term
| the degree of difference that must exist between 2 stimuli before the difference is detected. |
|
Definition
|
|
Term

|
|
Term
| what does it mean for attention to be selective |
|
Definition
| we attend to one stimulus then shift to another |
|
|
Term
| when we encounter an emotionally charged stimulus |
|
Definition
| emotion- induced blindness |
|
|
Term
| failure to detect unexpected events when our attention is engaged in a task |
|
Definition
|
|
Term
| a group of sensory neurons in the brain that help enable top down processing |
|
Definition
|
|
Term
| ex. getting used to cold water |
|
Definition
|
|
Term
| receptors in the retina that are light sensitive, but are not useful for color |
|
Definition
|
|
Term
| how many rods and cones do we have |
|
Definition
| cones- 6 million, rods- 120 million |
|
|
Term
| carries visual info to the brain for further processing |
|
Definition
|
|
Term
| neurons in the brains visual system that respond to particular features of a stimulus, visual cortex has neurons that are individually sensitive to different types of lines and angles |
|
Definition
|
|
Term
| travels quickly through the brain because of parallel processing, which is the simultaneous distribution of information across different neural pathways |
|

|
|
Term
| what are the three colors that make up the trichromatic theory? |
|
Definition
|
|
Term
| what is the name of the name of the sensation that the trichromatic theory seems to be un able to explain |
|
Definition
|
|
Term
| the opponent-process theory states that there are four colors grouped into what pairs? |
|
Definition
| red and green, blue and yellow |
|
|
Term
| what theory of color is correct? |
|
Definition
| both, the eye and brain use both methods to code colors |
|
|
Term
| this is a binocular cue to depth and distance in which muscle movements in the eye provide info about how deep and or far away something is |
|
Definition
|
|
Term
| the ability to perceive objects in 3D |
|
Definition
|
|
Term
| the recognition that objects are constant and unchanging, even though sensory input about them is changing |
|
Definition
|
|
Term
| what process does the cochlear implant mimic |
|
Definition
| uses small electric impulses to directly stimulate working nerves in the cochlea |
|
|
Term
| states that the inner ear registers the frequency of a sound based on how often auditory nerves fire |
|
Definition
|
|
Term
| what is the main limitation of the frequency theory |
|
Definition
| a single neuron has a max firing rate of 1000 times per second and therefore does not apply to tones that require a neuron to fire more rapidly. |
|
|
Term
| a cluster of nerve cells can fire neural pulses in rapid succession, alternate firing |
