Document Summary

Involve extractions of features to form what we call perceptions. We all seem to have the same sensory receptors. Yet, what you and i call the experience or conscious appears different. Transduction: receptors that translate one form of energy into another form of energy (something the nervous system can understand) Processing takes place at a higher level. Duration (how long does the stimulus occur) Detection of a minimum change in energy. The magnitude that a stimulus had 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. Subjects might be more or less willing to indicate that they have detected a low intensity stimulus. Thus, on some trials, a no-stimulus catch trial is included (refer to signal detection theory chart in lecture note)
