|
Pattern/Population Code |
Used to identify odor
|
|
|
Temporal Code |
Used to identify intensity ...of odor, of loudness, of brightness |
|
|
Place codonh Anatomical coding Labeled-line coding |
The location of the stimulated nerve reflects the location of the stimulus in the visual field |
|
|
Sensory adaptation |
decrease in sensitivity that occurs when a sensory system is repeatedly stimulated in exactly the same way |
|
|
Gestalt |
Whole is not necessarily equal to its parts
|
|
|
Structuralist |
Perception is when elementary particles come together |
|
|
Constructivist |
We construct our perception from degraded sensory input + guesswork based on knowledge and experience Continual adjustment of perception and action to the external input |
|
|
Gestalt principles |
law of proximity, good continuation, law of similarity, law of closure, law of good form, law of common fate |
|
|
Law of closure |
elements missing from an outline are filled in by the visual system |
|
|
JND |
Min change required in the intensity of something in order to detect that it is now stronger or weaker than it was |
|
|
Difference threshold |
JND |
|
|
Absolute threshold |
Minimum value of stimulus that can be detected Observers detect it 50% of the time |
|
|
Law of similarity |
Similar elements are part of the same figure |
|
|
Law of proximity |
Elements close to each other belong together |
|
|
Good continuation |
IF there are two options, we prefer straight line/smooth continuation/simplest interpretation |
|
|
Law of good form |
We prefer simple, uncluttered objects |
|
|
Law of common fate |
Elements that move together belong to the same figure |
|
|
Satisfaction of Search |
The finding of one stimuli interferes with the finding of another |
|
|
Response Bias |
A person's tendency to say "yes" or "no" when he/she is unsure whether he/she detected the stimuli |
|
|
Weber's fractions = Weber's law |
JND / absolute threshold = constant Relates JND to magnitude of stimulus |
|
|
Lightness cosntancy |
The brain will perceive a surface as equally light regardless of illumination |
|
|
Size constancy |
Mechanism that maintains the perception of some object as being of one size, in spire of the image's actual size varying on the retina |
|
|
Light from above |
People choose the image interpretation most consistent with a scenario where light is coming from above |
|
|
Transduction |
Conversion of physical energy into electrical potentials |
