Does access to spoken language really impact working memory?

Does access to spoken language really impact working memory?


It is a single-page site with some information, a link to the test and a short 5 question survey. The instructions as short and clear. 

I am a 4th year psych student conducting research on the impact of verbal language exposure on working memory. Working memory is described as our capacity to learn whereas IQ is a measure of what we have learned.

Working memory is important as it influences decisions on all areas of life, from early education through the entire school journey, to responses in a medical or emergency setting.

Historically, research studies have shown that Deaf people do not score as well on working memory tests. Many of these tests are based on learning strings of English Language words or numbers. The quality of how well they are remembered depends, according to the studies, on how well they are rehearsed in your head by saying them over and over – this is called sub-rehearsal in the phonological loop.

My question was a simple one – what happens if you have never heard spoken language?

Are these test biased against Deaf people

I believe the wrong measures have been used to test the working memory of Deaf people

My study uses a short memory test of colours and positions. I would really appreciate it if you and your colleagues could take the test.

I realise it is not perfect, I have no budget to put into this but I am hoping to spark renewed interest in study in this area – and thereby positively impact the education experience for future generations.

Many thanks for your time
