AB  - Adaptation to visual motion can induce marked distortions of the perceived 
      spatial location of subsequently viewed stationary objects. These positional 
      shifts are direction specific and exhibit tuning for the speed of the adapting 
      stimulus. In this study, we sought to establish whether comparable motion-induced 
      distortions of space can be induced in the auditory domain. Using individually 
      measured head related transfer functions (HRTFs) we created auditory stimuli that 
      moved either leftward or rightward in the horizontal plane. Participants adapted 
      to unidirectional auditory motion presented at a range of speeds and then judged 
      the spatial location of a brief stationary test stimulus. All participants 
      displayed direction-dependent and speed-tuned shifts in perceived auditory 
      position relative to a 'no adaptation' baseline measure. To permit direct 
      comparison between effects in different sensory domains, measurements of visual 
      motion-induced distortions of perceived position were also made using stimuli 
      equated in positional sensitivity for each participant. Both the overall 
      magnitude of the observed positional shifts, and the nature of their tuning with 
      respect to adaptor speed were similar in each case. A third experiment was 
      carried out where participants adapted to visual motion prior to making auditory 
      position judgements. Similar to the previous experiments, shifts in the direction 
      opposite to that of the adapting motion were observed. These results add to a 
      growing body of evidence suggesting that the neural mechanisms that encode visual 
      and auditory motion are more similar than previously thought.
