The flute is a family of musical instruments in the woodwind group. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening.
Dyslexia was first identified by German doctor Oswald Berkhan in 1881. 6 years later it was given the name dyslexia by Rudolf Berlin. It comes from the Greek words âdus,â which means hard or difficult and âlexis,â which means speech or word.
The visual theory (Lovegrove et al., 1980; Livingstone et al., 1991; Stein and Walsh, 1997) reflects another longâstanding tradition in the study of dyslexia, that of considering it as a visual impairment giving rise to difficulties with the processing of letters and words on a page of text.
