“…In visually complex environments, such as driving in a city with pedestrians and cars as possible obstacles, music has been found to be detrimental to driving performance as compared to no music (Brodsky, 2002;Hughes, Rudin-Brown, & Young, 2012), although this has not always been the case (Hatfield & Chamberlain, 2008;Ünal, Steg, & Epstude, 2012). Conversely, for less demanding situations or tasks, such as following a car and matching its speed (Ünal, de Waard, Epstude, Steg, 2013), maintaining lane position (Hughes, Rudin-Brown, & Young, 2012), or driving for an extended period of time (Oron-Gilad, Ronen, & Shinar, 2008), music has been shown to either facilitate or have no significant effect on driving indices. In a study on music's effect on mood, van der Zwaag, et al (2012) manipulated cognitive demand by varying lane width and found a pattern of results consistent with the combination of music and narrow lane width leading to worse performance, although the researchers did not find a significant interaction.…”
