Our study suggested for instance, that visual stimuli attract rubella children's attention almost immediately. Educationally speaking since the attention process is so strongly related to effective learning,it is important to investigate this area further. One of the main reasons why we think we are so succesful with some of our deaf-blind students is that we have explored the attention and memory processes and used our results in building a careful curriculum. In the development of communication, memory functioning is crucial. Sometimes these acts increase when the environment becomes more complex or when the child is left alone.
All educational researchers agree that stereotyped behaviour patterns interfere with learning.
We hypothesized that the duration of pregnancy, time of infection and or birthweight contributed to these motor-acts. Our conclusion was that these prenatal variables only play a modest role in the explanation of stereotyped behaviour patterns in our sample. Only infection time and birthweight were significant predictors for stereotyped behaviours that were centered around light. We were somewhat surprised to find that the degree of hearing loss was not an important predictor in the development of stereotyped behaviour. This is in accordance with our theorv that early visual deprivation has a great influence on the development of some abnormal behaviour patterns.
