|
Sensation
|
The process by which our sensory receptors and nervous system recieve and represent stimulus energies from our enviorment
|
|
|
Perception
|
Organizing and interpreting sensory information, to recognize meaningful objects and events
|
|
|
Bottom up Processing
|
Analysis that begins with the sense receptors and works up to the brains integration of sensory info
|
|
|
Top Down Processing
|
Information processing guided by higher level mental process, as when we construct percepts drawing on our experience and expectations
|
|
|
Psychophysics
|
The study of relationships between the physical characteristics of stimuli, such as their intensity and our psychological experence of them
|
|
|
Absolute Threshold
|
Minimun simulation needed to detect a particular stimulus 50 percent of the time
|
|
|
Signal Detection Theory
|
Predicts how and when we detect the presence of a faint singnal, amid noise assumes thereis no absoulute threshold
|
|
|
Subliminal
|
Below ones absolute threshold for concious awareness
|
|
|
Difference Threshold
|
Minimum difference that a person can detect between two stimuli wee experience te difference threshold just as a noticable difference
|
|
|
Webers Law
|
The principle that, to percieve their differenc, two stimuli must differ by a constant minimum percentage
|
|
|
Sensory adaptation
|
diminished sensitivity as a consequence of constant simulation
|
|
|
Transduction
|
Conversion of one form of nergy into another. Insesation the transfrminf of stimuus energies into neural impulses
|
