Card Set Information
Plan is in action...
Sensory receptors and nervous system receive and represent stimulus energies from our environment
Organizing and interpreting sensory information enabling us to recognize meaningful objects and events
Analysis that begins with the sensory receptors and works up to the brain’s integration of sensory info
Info processing guided by higher-level mental processes
Focusing of conscious awareness on a particular stimulus
Failing to see visible objects when our attention is directed elsewhere
Failing to notice changes in the environment
Study of relationships b/w physical characteristics of stimuli: intensity, psychological experience
Minimum stimulation needed to detect a particular stimulus 50% of the time
Signal detection theory?
When we will detect weak signals, measured as our ration of “hits” to “false alarms”
Subliminal priming difference threshold?
Below one’s absolute threshold for conscious awareness, activation, often unconsciously, of certain associations, thus predisposing one’s perception, memory or response
Principle that to be perceived as different, 2 stimuli must differ by a constant percentage (rather than a constant amount)
Diminished sensitivity as a consequence of constant stimulation
Conversion of one form of energy into another-transforming of stimulus energies: sight sound…etc into neural impulses
Distance from one wave peak to the next
Dimension of color that is determined by the wavelength of light
