This is called auditory sequential processing or short-term memory. This is the ability to take in bits or pieces of auditory input and to process it in a sequence. Eventually a familiar couplet or phrase is also recognized and processed as a single bit of information. The sequence grows from an initial sound, to an approximation, to a word, to a couplet, to a 3-4 word phrase, to a sentence and then a string of sentences. Our perception is that anyone over the age of seven with a digit span of less than seven has a deficiency in auditory sequential processing.
Sequential processing is vital to normal function.
For example, if you are over age seven but process say, at a 4 or 5 then basically your brain is processing as that of a 4 or 5 yr old child. Auditory sequential processing determines the ability to process language, to think, to think conceptually, and to express oneself in words. First, tell the child we are going to play a fun game. In a monotone voice, with a one-second pause give a direction. Initially, start with one direction.
