This difficulty is caused by a child"s inability to comprehend "the intentions of others through their words and language, emotions and expressions" (Kroll, 1998). The hyperlexic child will "find it easier to grasp language information that they see, better then that which they listen to" (Kroll, 1998). In a social situation where there is only verbal interaction the child with hyperlexia will not understand the intention of the spoken words so he will be apt to be a loner and play by himself. Children with hyperlexia "tend to be aloof from other children since they do not know what to say to facilitate interactions" (Kupperman).

             Repetitive behavior is the second important component of hyperlexia. This behavior may exhibit itself in echolalia, perserveration and engaging in repetitive patterns of behavior such as reading with an abnormal intensity, "repetitive motor mannerisms (hand flapping) or preoccupation with parts of objects" (Bligh, 1995). The hyperlexic child learns expressive language by echoing what he hears. He will memorize complete sentences and phrases without understanding the meaning of the words. These same phrases will then be repeated verbatim at a time when it may be totally inappropriate. The hyperlexic may also have mild to severe stuttering problems. He has an intense need to keep routines and may engage in ritualistic or self-stimulating behavior. He has sensitivity to loud noises and strong odors.

             Communication problems keep the hyperlexic child from acting appropriately with other people. In addition to the inability to comprehend the intention of others he will also be unable to express himself and his intentions. He may repeat a phrase he has heard and memorized because he is unable to formulate and organize his own thoughts. The hyperlexic child also has difficulty understanding directions and listening to group instructions.
