9．Technological change is everywhere and affects every aspect of life，mostly for the better．However，social changes are brought about by new technology are often mistaken for a change in attitudes．
An example at hand is the involvement of parents in the lives of their children who are attending college．Surveys （調(diào)查） on this topicsuggests that parents today continue to be"very"or"somewhat"overly-protective even after their children move into college dormitories．The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago．This usually interpreted as a sign that today's parents are trying to manage their children's lives past the point where this behavior is appropriate．
However，greater parental involvement does not necessarily indicate that parents are failing to let go of their"adult"children．
In the context （背景） of this discussion，it seems valuable to firstfind out the cause of change in the case of parents'involvement withtheir grown children．If parents of earlier generations had wanted to be in touch with their college-age children frequently，would thishave been possible？Probably not．On the other hand，does the possibility of frequent communication today mean that the urge to do so wasn't present a generation ago？Many studies show that older parents-today's grandparents-would have called theirchildren more often if the means and cost of doing so had not beena barrier．
Furthermore，studies show that finances are the most frequentsubject of communication between parents and their collegechildren．The fact that college students are financially dependent ontheir parents is nothing new； nor are requests for more money to besent from home．This phenomenon is neither good nor bad； it is afact of college life，today and in the past．
Thanks to the advanced technology，we live in an age of bettered communication．This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college．But it is useful to bear in mind that all such changes come from the technology and not some imagined desireby parents to keep their children under their wings．
