The magical number seven, plus or minus two: Some limits on our capacity for processing information. Down Syndrome Research and Practice6 2 The short-term memory of profoundly Deaf people for words, signs, and abstract spatial stimuli. The examiner, a Deaf adult, asked the participants to try their best to remember a list of signed digits which would appear on the screen of the laptop. One other point to note about these studies is that they tend to lack an independent measure of whether rehearsal is being acquired, or is becoming more efficient, as a result of training. Verbal information enters the phonological store, and is held there in a speech-based, phonological code. The vowel sound for digits 6 and 9 is a diphthong.

Baddeley's Model of Working Memory is a model of human memory proposed by Alan Baddeley and Graham Hitch inin an attempt to present a more accurate model of primary memory.
Working memory splits primary memory into multiple components. Baddeley and Hitch () argue that the picture of short-term memory (STM) sketchpad and phonological loop) and relates them to long term memory (LTM). Baddeley's Model of Working Memory is a model of human memory It consists of two parts: a short-term phonological store with auditory memory traces that are subject to rapid decay and an articulatory.
Ordered short-term memory differs in signers and speakers: implications for models of short-term memory.
With this knowledge, interpreter and transliterator training programs may be further informed as they design appropriate encoding and recall exercises to train students who are not native signers for accurate and efficient handling of signed messages. In other words, if an individual is using speech-based rehearsal then only irrelevant articulations using the articulators of speech will impede the function of the phonological loop Murray, In this case intervention may be best aimed at moving away from the need to use verbal short-term memory, to bring in relatively stronger systems.
However, any differences found in short-term memory spans between groups is not likely to be caused by differences in sign language fluency, based on previous studies that have compared short-term memory ability in more and less experienced signers and interpreters.
Short-term memory in signed languages: Not just a disadvantage for serial recall. Instead the experimenter asked the child to name each item in the list in turn.

Similar results are reported by Laws, MacDonald and Buckley who found that a pointing response mode did not improve recall in comparison to a standard, verbal serial response. Bonita Squires.
The phonological loop model for retention of auditory verbal material in Short-term memory for word sequences as a function of acoustic, semantic and formal. Short-term memory for word sequences as a function of acoustic, semantic and formal rly Journal of Experimental Psychology,18, –
If this were the case then the actual speech rate of individuals with Down syndrome would be irrelevant, because in the absence of rehearsal there would be no correlation between speech rate and memory span unless mediated by output delay effects, see above.
If the phonological loop is used for sign-based rehearsal, then when participants are asked to memorize signed stimuli while doing manual irrelevant articulations, their short-term memory spans will be shorter than without the irrelevant articulations. A second problem for Hulme and Mackenzie 's position is that there is evidence that rehearsal does not occur in typically developing children until around the age of seven years see Gathercole,for a full review.
This implies that hearing deficits are not a serious input problem in verbal short-term memory. Articulatory suppression conditions were manipulated to determine if participants would use a speech- or sign-based code to rehearse lists of signed items. This led to the following question: Why were the reported mean ASL short-term memory digit spans shorter than the mean TSL short-term memory digit span for hearing bilinguals? Other studies that measured ordered lexical sign spans of hearing bimodal-bilinguals found mean spans of 5.
