摘要

Prior studies have shown that training with stroboscopic viewing improvedperformance on visual tasks, such as motion coherence thresholds, and performance oncoincident anticipation tasks (Appelbaum, Schroeder, Cain, & Mitroff, 2011; Smith &Mitroff, 2012). In stroboscopic viewing, individuals wear occlusion goggles whichpresent an intermittent view of the environment. It is assumed that training during“degraded” viewing will enhance subsequent performance during unimpaired viewing.We examined whether training with stroboscopic viewing can improve time-to-collision(TTC) judgments, which have importance in real-world tasks such as driving, using aprediction motion (PM) task (Schiff & Detwiler, 1979). The PM task is particularly wellsuitedfor stroboscopic training because the task involves extrapolation of the object’smotion after it disappears (DeLucia & Liddell, 1998; Schiff & Oldak, 1990). Instroboscopic viewing, the object appears and then disappears, but does so repeatedlythroughout the object’s approach. During periods of occlusion, observers putativelyextrapolate the object’s motion. When the object reappears, observers get feedback ontheir extrapolation. Thus, they get feedback on their extrapolation throughout the object’sentire approach.
