Human Vection Perception Using Inertial Nulling and Certainty Estimation: The Effect of Migraine History.

Miller MA, O'Leary CJ, Allen PD, Crane BT - PLoS ONE (2015)

Bottom Line: This study examines the effect of the duration of visual field movement (VFM) on the perceived strength of self-motion using an inertial ing (IN) and a magnitude estimation technique based on the certainty that motion occurred (certainty estimation, CE).For the IN method, an inertial ing motion was delivered during this final 1s of the visual stimulus, and subjects reported the direction of perceived self-motion during this final second.Together, these results suggest that vection may be measured by both CE and IN techniques with good correlation.

ABSTRACT
Vection is an illusory perception of self-motion that can occur when visual motion fills the majority of the visual field. This study examines the effect of the duration of visual field movement (VFM) on the perceived strength of self-motion using an inertial ing (IN) and a magnitude estimation technique based on the certainty that motion occurred (certainty estimation, CE). These techniques were then used to investigate the association between migraine diagnosis and the strength of perceived vection. Visual star-field stimuli consistent with either looming or receding motion were presented for 1, 4, 8 or 16s. Subjects reported the perceived direction of self-motion during the final 1s of the stimulus. For the IN method, an inertial ing motion was delivered during this final 1s of the visual stimulus, and subjects reported the direction of perceived self-motion during this final second. The magnitude of inertial motion was varied adaptively to determine the point of subjective equality (PSE) at which forward or backward responses were equally likely. For the CE trials the same range of VFM was used but without inertial motion and subjects rated their certainty of motion on a scale of 0-100. PSE determined with the IN technique depended on direction and duration of visual motion and the CE technique showed greater certainty of perceived vection with longer VFM duration. A strong correlation between CE and IN techniques was present for the 8s stimulus. There was appreciable between-subject variation in both CE and IN techniques and migraine was associated with significantly increased perception of self-motion by CE and IN at 8 and 16s. Together, these results suggest that vection may be measured by both CE and IN techniques with good correlation. The results also suggest that susceptibility to vection may be higher in subjects with a history of migraine.

Certainty Estimate—Individual Data for Experiment 2.A-C represent individual data means for 1s, 4s, and 8s trials, respectively. 8 stimuli were delivered in each trial as either the looming or receding VFM. Mean certainty estimates for each subject were collected with looming VFM represented with a red solid circle, receding VFM responses are represented with a blue square. Error bars represent 95% CI.
