The present study investigated whether continuous presentation of the same background photograph produces context-dependent recognition. Nakajima, Isarida, & Isarida (216) investigated video-context-dependent recognition in Context load (the number of items presented per context) 1, 6, and 18. Continuous presentation of the same video produced context-dependent recognition discrimination in Context load 6 but not in Context load 18. Shortening the study time to one third produced context-dependent recognition discrimination even in Context load 18 (Kubota, Nakajima, Isarida & Isarida, 216). The present study replicated the above experiments by using background photograph context instead of video video context in Context load 1 and 6. Context load 1 showed context-dependent recognition discrimination but not in Context load 6. Additionally, shortening the study time to one third did not produce context-dependent recognition discrimination. The present results imply that continuous presentation of the same background photograph will disable the photograph from functioning as context.
