Final answer:
The MIS of a subject recalling words through different cues cannot be precisely calculated without a specific scoring system.
Step-by-step explanation:
The Memory Index Score (MIS) of a subject who recalled 2 words without cues, 2 words with a category cue, and 1 word with a multiple-choice cue can be calculated by assigning different weights to each type of recall. Typically, recall without cues is more challenging and thus may be weighted more heavily than recognition with cues.
However, without a specific scoring system provided, we cannot calculate an exact MIS. The learning and recall process mentioned imply a deep connection with the long-term memory storage system, which involves encoding, storage, and retrieval of information.
The subject demonstrated recall by retrieving two words without cues, utilized recognition to identify two words with category cues and showed relearning ability by recalling one word from a multiple-choice cue. This indicates engagement of various memory-enhancing strategies and levels of processing to retrieve stored information.
