The amount of technology helping college students stay in touch with family and friends back home can be a blessing and a curse, a Purdue University media expert says.

Glenn Sparks says people used to leave home to establish new friends and contacts. Today, computers and cell phones keep them in touch with the old gang.

"Technology can be great for staying in touch, but it may also create a trap that can discourage people from becoming interested in the people in their new environment," Sparks said. "Instead of making the effort to meet new people, some students may find it easier to watch their favorite television show or play games on the Internet. Eventually, these students may find themselves alone and isolated, and that could affect their performance in school as well as their overall emotional health."

Sparks also said that when getting to know new people, it's better to meet them for a meal, go for a walk or just sit and talk

Sparks is co-author of "Refrigerator Rights," a book that studies how most Americans are lacking quality relationships in their lives.
