Arrange the following in sequences as per Atkinson and Shiffrin's model of memory when the information is processed:
(a) Short term memory
(b) Elaborative rehearsal
(c) Long term memory
(d) Attention
(e) Sensory memory

Correct option is C

​According to Atkinson and Shiffrin's Multi-Store Model (1968), information processing follows a sequential pathway. First, environmental stimuli enter (e) Sensory memory where information is briefly held (less than 1 second for iconic, 2-4 seconds for echoic). (d) Attention selectively filters relevant information from sensory memory for further processing. Attended information transfers to (a) Short-term memory (STM) with limited capacity (7±2 items) and duration (15-30 seconds). (b) Elaborative rehearsal involves deep, meaningful processing that transfers information from STM to (c) Long-term memory (LTM), enabling permanent storage and retrieval.

Information Booster:
● Atkinson-Shiffrin Model (1968) proposed three distinct memory stores with different capacity, duration, and encoding characteristics.
● Sensory memory includes iconic (visual), echoic (auditory), and haptic (tactile) registers that preserve sensory impressions momentarily.
● Attention acts as the gateway mechanism determining which sensory information receives conscious processing and STM encoding.
● Maintenance rehearsal (repetition) keeps information in STM temporarily, while elaborative rehearsal creates semantic connections for LTM encoding.
● Working memory model by Baddeley and Hitch (1974) later refined STM concepts, emphasizing active processing over passive storage.
● The model emphasizes unidirectional flow from sensory to short-term to long-term memory through controlled processing stages.
