On the other hand, we also need to appreciate the
difficulties learners go through in trying to
comprehend the content of the websites when the
good intentions of the internet are poorly organized
and screen layouts were in consistent. Some web
pages may include content that flickers in order to
capture the viewers’ attention. This can present
discomfort on the part of the user. Some of the
content can be at the rate of 2 and 55 hertz and this
can trigger seizures for those who may be susceptible
to the flickers (http://www.washington
