“…However, the number of studies on this method, and the number using it, has remained small albeit steady since this period. In the recent past, the IDM has been utilized in a series of studies published after 2000 (e.g., Andersson, 2004; Huneke, Cole, & Levin, 2004; Newell, Weston, & Shanks, 2003; Weenig & Maarleveld, 2002), while it has been developed further by some (e.g., Anderson, 2001; Jasper & Shapiro, 2002; Johnson & Willemsen, 2004). One barrier to the more widespread use of the method, especially for applied research, might be that it has been criticized sharply with respect to the external validity of results, by reason that the information acquisition context is regarded as too artificial (Kroeber-Riel & Weinberg, 2003, p. 286).…”
