Echoic memory: after a sound is heard, a brief continuation of the activity in the auditory ! system. Working memory: part of stm; like a mental scratchpad ! Selective attention: focusing (voluntarily) on a selected portion of sensory input ! (e. g. selective hearing)! Phonetically: storing info by sound; how most things are stored in stm.
