In the Atkinson and Shiffrin model, which of the three basic components holds environmental stimuli temporarily as the information gets converted into a usable mental form?

Sensory memory

Explanation: According to the memory theory proposed by Richard Atkinson and Richard Shiffrin. The theory proposed that human memory has three basic components namely; The Sensory memory, short term memory and the Long term memory.

However, the component which holds environmental stimulus temporarily as it gets converted into usable mental form or before it is transmitted to short-term memory is the Sensory memory or Sensory register. The Sensory register detects and temporarily keeps a stimulus for use by the short-term memory when attention is given to such information. Otherwise the stimulus is discarded before it could be passed to the short-term memory.
