Directional collisions during a route-following task

Abstract: Neurologically normal people tend to collide with objects on the right side more frequently than with objects located on the left side of space. This phenomenon could be attributable to pseudoneglect wherein individuals selectively attend to the left field. The current study investigated this effect using a virtual route-following task that was presented centrally, in the lower field, and in the upper field. Handedness was also examined. Fifty-two participants (four left handed) completed this task, and when p… Show more

“…A rightward bias has also been reported for a virtual route-following task when it was presented in the upper visual hemispace for a group of North Americans. Conversely, when the task was presented in the lower hemispace, a leftward bias was observed (Thomas et al, 2009). Finally, more leftward collisions have been reported by Hatin et al (2012) for an ambulatory task in a North American population.…”

“…One possibility is that the rightward bias may reflect underlying motor asymmetries (Boyadjian, Main, & Danion, 1999;Fujikake et al, 2011) or turning biases mediated by a vestibular (Robertson et al, 1994) or dopaminergic (Mohr, Landis, Bracha, Fathi, & Brugger, 2003;Mohr, Landis, Bracha, Fathi, & Brugger, 2005) asymmetry. Although these motor/vestibular mechanisms could explain asymmetries for ambulatory tasks, they have difficulty explaining asymmetries when navigating a motorized wheelchair (Nicholls, Hadgraft, et al, 2010) or in virtual-reality paradigms (Jang et al, 2009;Kim et al, 2010;Thomas, Stuckel, Gutwin, & Elias, 2009)-because these tasks operate independently of the motor effectors. In addition, vestibular effects on veering and turning behavior are typically observed only when participants are blindfolded (Cohen, 2000;Roberts, Cohen, & Sangi-Haghpeykar, 2011).…”

“…Lateral biases have also been identified on more real-world behaviours, such as passing through a doorway (Nicholls, Loftus, Mayer, & Mattingley, 2007;Nicholls, Loftus, Orr, & Barre, 2008), choosing a seat in the theatre (Okubo, 2010), completing a route following task (Thomas, Stuckel, Gutwin, & Elias, 2009) or multiple-choice questionnaire response patterns (Nicholls, Orr, Okubo, & Loftus, 2006). The leftward lateral biases seen on laboratory measures also occur on more real-world types of tasks, making it of extreme importance to understand more clearly how and why these biases emerge.…”

“…Participants were encouraged to follow the route as quickly as possible and the number of collisions made with both the left walls and the right walls was recorded. Thomas et al (2009) also explored the effect of upper and lower VF presentations on the number of collisions with each wall. Thomas and Elias (2010) then examined whether the strength of the left bias on the greyscales task would be affected by VF or viewing distance and whether these factors would interact.…”
