Final answer:
In receptive identification, the recommended array size for items is between 3-5 in a linear pattern, to align with the average individual's short-term memory capacity and the principles of cognitive psychology.
Step-by-step explanation:
In receptive identification, it is recommended that the array of items should stay between 3-5 items in a linear pattern. This recommendation is based on the cognitive psychology understanding of short-term memory capacity. Studies have shown that the average short-term memory capacity of individuals is roughly 7 plus or minus 2 items; however, contemporary research by Cowan (2010) suggests that a more accurate range is 4 plus or minus 1 item. Therefore, keeping the array sizes within this range can facilitate better memory and learning outcomes. Including too many items, or creating a display that is messier, could impair the ability to quickly and correctly identify the requested item. It's beneficial to keep the array organized to enhance cognitive processing, as highlighted by examples of the Gestalt principles of similarity and proximity, which show how our perceptions are influenced by the arrangement of stimuli.
