Reading is a complex visual task. It requires identification and localisation of the orientation of the lines of which letters are constructed, memory of what is seen, followed by association with meaning and language (Knowler 1990). There can be a number of reasons for a child to have problems with reading. In many cases, reading problems result from the eyes being unable to scan easily and effortlessly along a line of print, which is vital to be able to read. Other poor readers, by concentrating on getting their eyes to scan the line, are unable to recall what they have read, and this is frequently misdiagnosed as being a ‘short term memory problem’. As a result of concentrating on controlling the eyes concentration and short-term memory become impaired.( INPP ltd, 1 Stanley Street, Chester, CH1 2LR, United )
