![]() It has been suggested that children with dyslexia have impairments in the phonological loop because they perform poorly on digit span tasks-they might struggle with holding the numbers in their mind in general, rehearsing the correct order, or have difficulty with increased cognitive load. This study focused on digit span performance in children with dyslexia. In the digit span backward task, working memory is assessed by additionally requiring the manipulation of item order. In both the digit span forward and backward tasks, phonological short-term memory (i.e., the phonological loop) is assessed. We can assess the ability to both hold phonological information in mind and manipulate it by asking someone to immediately repeat a list of spoken digits in the reverse order from how they were presented (digit span backward task). We can assess the ability to briefly hold phonological (speech) sound information in mind by asking someone to immediately repeat a list of spoken digits in the correct order (digit span forward). The ability to just hold information – to store it briefly in mind – has been referred to as short-term memory. Working memory is the ability to hold and manipulate information in the current focus of attention. Journal of Clinical and Experimental Neuropsychology, 26(1), 31–42.
