This paper discusses a study that examines the responses of introverted and extraverted college students (N=72) to the use of e-mail. Results show that extraverts use e-mail as a form of procrastination more than introverts and that extraverts find e-mail more disruptive to their work than introverts. No significant differences were found in terms of time spent on e-mail, but the range of time spent daily was much greater for extraverts. Neither were there significant differences for the number of times per day that participants checked their e-mail, nor on indicators of subjects' responsiveness to e-mail. However, ranges of responses varied. All participants perceived e-mail as generally valuable. Over two-thirds of respondents leave their computer on throughout the day. Nearly 90% communicate via e-mail at least daily and reported checking e-mail messages more than once a day on weekends as well. However, only 15% spend greater than an hour per day on e-mail. Over 90% report that e-mail at least occasionally disrupts their work and acknowledge their occasional use of e-mail to procrastinate. Over 95% report that junk e-mail bothers them; only 15% belong to discussion groups. An alarming 20% actually read less than half of the message they receive and only 7% reply to all of their e-mail. In contrast, two-thirds expect others to respond to message they send within a day. Nearly half believe that e-mail is secure and private, yet 50% report trying to avoid revealing personal information over e-mail. Roughly 10% see computer technology as always reliable and only 5% report experiencing technical difficulty when accessing e-mail. Only one-fourth feel frustrated and/or negative about needing to learn to use new software application. Overall, this study suggests that e-mail technology may be creating a greater burden for extraverts than for introverts. Topics for future research in this area are discussed. (MKA)
