“…Studies using a reaction time (RT) task in which a target was presented along the pursuit trajectory have suggested that, during smooth pursuit, attention moves ahead of the pursued object along the trajectory (Tanaka, Yoshida, & Fukushima, 1998;van Donkelaar, 1999;van Donkelaar & Drew, 2002). For instance, van Donkelaar and Drew had participants view a display containing a central cross ("×") and eight peripheral circles, four placed horizontally on the right side of the cross, and four on the left.…”

“…They argued that previous findings of faster RTs for a target ahead of the pursuit stimulus than for a target behind it (e.g., van Donkelaar & Drew, 2002) reflected a spatial shift of attention triggered by the abrupt onset of a target (Theeuwes, Kramer, Hahn, & Irwin, 1998;Yantis & Jonides, 1990) rather than the steadystate allocation of attention during pursuit. To investigate the spatial allocation of attention during pursuit, Lovejoy et al used a non-RT task that minimizes abrupt onsets (Deubel & Schneider, 1996).…”

To examine the spatial shift of attention during smooth pursuit, we measured reaction times (RTs) to a visual target that appeared during pursuit. Participants pursued a moving row of circular frames and responded to a target presented within one of the frames. The results showed large RT differences between stimulus velocities up to 5º/s and 10º/s or above. RTs were faster for a target appearing in the pursuit direction than for one in the opposite direction. When an auditory precue was presented, the RTs during pursuit at 10º/s were faster with increases in the stimulus onset asynchrony (SOA) between the cue and the target. Furthermore, RTs were faster in the cued than in the uncued direction. These results not only support the idea that RTs during pursuit reflect the operation of attention, but also suggest that attention during pursuit can be shifted by the abrupt onset of a target stimulus and/or by prior information regarding the onset of a target stimulus.

“…For example, Van Donkelaar & Drew (2002) have demonstrated that reaction times to changes in stimuli are reduced if they occur 1-2 degrees in front of the actual pursuit target, but increased if they occur 1-2 degrees behind, suggesting that allocation of attention is biased to a position slightly in front of the target during pursuit. Chen & Holzman (2002) found that performing a brief secondary task (judging which of two horizontal gratings presented above and below the pursuit target has the higher spatial frequency) at the same time or 450 ms after pursuit onset led to impairments in the maintenance of pursuit.…”

Attentional processes have traditionally been closely linked to the production of saccadic eye movements, but their role in the control of smooth pursuit eye movements remains unclear. In two experiments we used dual task paradigms to vary the attentional resources available for pursuit eye tracking. In both experiments we found that attentionally demanding secondary tasks impaired smooth pursuit performance, resulting in decreased velocity and increased position error. These findings suggest that attention is important for the maintenance of accurate smooth pursuit, and do not support the hypothesis that pursuit is a relatively automatic function that procedes optimally in the absence of attentional control. These results add weight to the suggestion that a similar functional architecture underlies both pursuit and saccadic eye movements.

“…The extra 10 ms difference might be due to biomechanics, or switching of attention from one hemisphere to other. Human psycho-physical data (Van Donkelaar & Drew, 2002) show that attention during pursuit is either on the pursued target or ahead of it. So, for a forward saccade, the attentional resources of the same hemisphere are needed.…”
