SENSORY MEMORY

Elaboration of the Structural Model

From our previous discussion, recall the Structural Model of memory suggested by Atkinson and Shiffrin. The structural model suggests three storage systems (places); Sensory Store, Short-Term Memory (STM), Long-Term Memory (LTM).

Information moves through these systems under the control of various cognitive processes (attention, rehearsal, etc.). The distinctions among the three structures is made on the basis of four characteristics which emerged from the literature; capacity, duration, type of code, and mechanism of loss. The model originated as a way of explaining some of the early research findings which argued for a duplex theory. In this section, we want to explore the particular nature of Sensory Memory or the Sensory Store.
