The availability of the personal computer (PC), statistical software, and the Internet has had undeniable effects on I-O psychology. Without such technological advances, for instance, there’d be no virtual teams, no computer-adapted testing, and no cyberloafing. To better appreciate the impact of technology on the current state of our discipline, it’s helpful to reflect on the technology used in the recent past. In preparing this installment of the History Corner, we interviewed nine seasoned I-O psychologists: Terry Beehr, Ilene Gast, Lawrence Hanser, Milton Hakel, Norman Peterson, Susan Reilly, Neal Schmitt, Paul Thayer, and Lauress Wise. We asked them each to describe the technology they used during their early careers to conduct data analysis, and we asked them to reflect on how technological changes have affected the way in which I-O psychologists conduct research. In the following sections we discuss how calculators, early computers, and PCs were used “back in the day” to conduct data analysis. We then discuss how I-O psychologists wrote their research reports prior to the advent of PCs and word processing programs.
