Research on the impact of CC has been limited largely to individuals with learning disabilities (Kirkland, Byrom, MacDougall, & Corcoran, 1995), hearing impairments (Yoon & Choi, 2010), individuals learning English as a second language (Garza, 1991; Taylor, 2005; Winke, Gass & Sydorenko, 2010), and children learning to read (Linebarger, 2001). Across all these studies, the use of captioned video resulted in increased comprehension and/or faster learning compared to students who did not see captioning. We found only one previous captioning study that utilized a sample of individuals from a general population. Ruggiero (1986) randomly divided 80 undergraduate students into two groups, who were then showed the same 30-minute video. One group viewed the video with captions, and the other without. A subsequent 35-item assessment showed no statistical difference in test scores of the two groups. We were able to locate only an abstract description of the Ruggiero study that was presented at a conference in the late 1980s. Therefore, more detailed information about how the study was conducted was not readily available. About 20 percent of Americans identify as having some type of impairment that may impact one or more major life activities (U.S. Census Bureau, 2011). AT is often needed to ensure independence in work, educational, community and home settings. The employment rate for Americans with disabilities is significantly lower compared to individuals without disabilities (U.S. Bureau of Labor Statistics, 2016). One study found that most employed individuals with disabilities were using one or more AT devices (Yeager, Kaye, Reed, & Doe, 2006). The researchers surveyed people using the Center for Independent Living in California and found that the majority (54.2 percent) employed individuals were using some form of assistive technology. Work benefits included productivity and hours worked, as well as improve attendance.
