![]() In dichotic listening paradigms, sometimes the research goal is to examine selective attention. In divided attention, the individual must juggle their cognitive resources between two or more tasks. In this context, shadowing is used to study divided attention. Participants are asked to repeat or listen to the content of a message while performing a task such as driving in a simulator. They both involve the presentation of an auditory stimulus while being tasked with a secondary requirement.įor example, a common use of shadowing is in the study of mobile phone use and driving. The shadowing procedure and dichotic listening task are very similar. When the participant initiates speech production, the tongue makes contact with the palate, which then serves as a measure of reaction time between hearing speech and producing speech. The research involved placing an artificial palate in the research participant’s mouth. The research was conducted by the Leningrad School of Phonology, founded by Ludmilla Chistovich and her husband Valerij Kozhevnikov. The shadowing technique was designed to study speech perception and speech production processes in the late 1950s (Pickett, 1985). This includes examining how mobile phone use effects learning outcomes (Kuznekoff & Titsworth, 2013), or pedestrian behavior such as crossing the street (Hatfield & Murphy, 2007). In particular, the shadowing procedure has been used to examine how mobile phone use affects driving (Kaplan, et al., 2015), to train language translators (Lambert, 1992), and in second language instruction (Martinsen et al., 2017).Ī modified version of the shadowing procedure has been used to study selective attention. The original shadowing experimental procedure and similar methodologies have been used to study a wide range of cognitive phenomena. In later studies, the method was altered slightly to include performing other tasks simultaneously. “…a paced, auditory tracking task which involves the immediate vocalization of auditorily presented stimuli” (p. The original shadowing task involved paced audio tracking. At other times, it will involve asking someone to attempt to do two tasks at once (like texting and driving on a controlled track) to study the effects on road safety.Īnother common example of shadowing is testing a person’s cognitive and attentional skills by asking them to repeat a message word-for-word in real-time while other stimuli (such as music or background speech) are vying for the participant’s attention. Generally, it will involve asking the participant to repeating information immediately, such as asking an interpreter to interpret someone’s speech into another language at real-life speed. It involves exposing a participant to several several stimuli simultaneously in order to track and measure their ability to pay attention to one stimulus and process it, to the exclusion of others. It provides insight into a participant’s selective attention, divided attention, intentional blindness, auditory processing speed, and working memory. Shadowing in psychology is a method to study a person’s attention skills.
