Document Summary

(ow do we transform the earth"s external energy (cid:523)stimulus input(cid:524) into what. We all seem to have the same sensory receptors. Yet, what you and i call the experience or consciousness of the sensation will eventually become a meaningful percept. seems to be quite different. Processing (presumably) takes place at the higher level. Detection of minimum energy required to stimulate receptor. Minimum amount of energy required to detect the stimulus on 50% of trials. The magnitude that a stimulus has to be increased (or decreased) in order for a change to be detected is a constant proportion (note not a constant addition) The absolute threshold may vary for reasons that have nothing to do with sensitivity. Subjects might be more or less willing to indicate that they have detected a low intensity stimulus. Coding of sensory modality (but how do we experience one modality as. Limitations of neuron"s all-or-none law amplitude modulation not possible.
