Task 3 - Number Recall (Visual) - This is a sequenced-digit, recall task designed to teach the utilization of techniques to enhance storage and recall, expand working memory and improve one’s ability to manipulate information in working memory. The three levels address immediate recall of the information in the same format as presented (level 1), immediate recall in reverse order (level 2) and recall in same order as presented but after a brief delay (level 3). Techniques that can be employed (and should be discussed with the student) include:
1. talking aloud,
2. rehearsing the sequence (aloud) several times before responding,
3. chunking the digits and
4. being vigilant for patterns that might appear in the sequences.
Chunking refers to strategically grouping the digits. For example, for a four-digit number like 8462, one could study it and then recall it in the format eighty-four, sixty-two. For a five-digit number like 95728, one could chunk it in the format nine-fifty-seven, twenty-eight. This reduces the information from 5 discrete pieces to two pieces. The primary object here is not to just teach someone a better technique for recalling numbers but to expand their working memory skills in general and instill in the student that one should spend time thinking of a technique that might facilitate recall of whatever they are trying to memorize. So, when studying for a history test or learning scientific facts in science class, one should analyze the data to be learned, organize it into an easier format, rehearse it sufficiently (aloud) and repeat all of this on multiple occasions.
