Sensory memory: sensory: having to do with a sensory system (rather than a higher order cognitive aspects, modality: the mode of perception/presentation (visual, auditory, olfaction, precategorical: based on low-level sensory information. There must be a distinction between perception (info that is still present in the environment) and memory (the stimulus is gone, must remember, perhaps with a sensory trace) These (cid:862)tra(cid:272)es(cid:863) are sensory memory and they tend to be short lived.
