“…For example, only three studies Crowell, Anderson, Abel, & Sergio, 1988;Wilson, Boni, & Hogg, 1997) have examined task clarification separate from other intervention components. In addition, only a few studies (Austin et al, 1993;Miligan & Hantula, 2005;Mueller, Moore, Tingstrom, & Doggett, 2001) have examined the effects of visual prompts in isolation. Finally, although the use of feedback is ubiquitous in the OBM literature, Alvero et al (2001) found that only 31% of feedback articles published in JOBM between 1985 and 1998 examined feedback alone (i.e., feedback in the absence of other intervention components).…”
