I am trying to figure out how much of brain exercising can improve the word discrimination. Is poor word discrimination a physical deficiencies or is it just lack of brain exercising?
I notice that if I listen to a sentence on telephone, I cannot discriminate much of it, however if I read the same sentence first (expecting what the word should be, then listen to the same sentence, I can hear every words clearly. If the word discrimination is just physical ( for example loss of hair cells on cochlear), then why it can be heard clearly after knowing the sentence? If the brain cannot decode words because the nerves cannot pass the sound information accurately, but why after knowing the sentence, the nerves can deliver the sounds correctly?
Would you please share with me your word discrimination experiences. Do you hear it much more clearly after you know the sentence? In your daily basis, do you use captioning more than listening and do you feel any side effect? Do you do any brain exercise for improving the word discrimination? If so, how effective is it?
