Incoming information is encoded as chunks in STM by referencing LTM. Mostly STM operates by auditory coding of input stimuli. We hold information in STM by auditory rehearsal.

After performing this experiment

1. You will find evidence of information being stored in STM by means of visual coding of input stimuli.(Posner and his associates [Posner,1969] found that , at least part of the time , information is coded visually in STM.)
