• Intensity coding - receptors can detect and code
strength or magnitude of the stimulus.
• Graded response: the greater the stimulus the greater the
response. 2 ways!!!!
1) spatial summation--- the more sensory receptors that are stimulated
the more intense the perception 2) temporal- the sensors ﬁre more rapidly • Spatial Summation - The larger number of receptors that
are stimulated, the stronger the perceived stimulus.
• Temporal Summation - A strong stimulus causes
receptors to fire at a higher frequency than a weak
stimulus. General properties of receptors
• Adequate stimulus - most
receptors are built to respond
only or preferably to one kind of
stimulus energy • Modality - when a specific
receptor is stimulated (w/ an
adequate stimulus) to cause a
