Document Summary

Involves extractions of features to form a perception. How is my experience of the universe different from yours: individual differences subjective consciousness. All individuals seem to have the same sensory receptors: experience and consciousness of the sensation is all. Transduction: receptors transduces one form of energy into another form of energy. At this level, it is more or less objective. Processing (presumably) takes place at a higher level than sensory. Might involve consciousness: may not be conscious of the fact that you are extracting features. Features to be extracted: frequency (how often?, intensity (how much?, location (where is it in space spatial location, duration (how long does the stimulus occur?) 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 (not: not a constant addition)
