Sensation

Perception
brain’s psychological process to make sense of the stimuli
Absolute Threshold
minimal amount of stimulation in order to detect a stimulus
Signal Detection
the way we measure absolute thresholds, involving presenting stimuli of varying intensities to a research participant in order to determine the level at which he or she can reliably detect stimulation
Differential Threshold (Just Noticeable Difference, JND)
smallest difference needed in order to differentiate between 2 stimuli
Webers Law
bigger stimuli require larger stimuli to be noticed
Bottom-Up Processing
build up to perception from the individual piece
Top-Down Processing
stimulus we’ve experienced in our past will influence how we process new ones
