Using eye tracking, this study provides compelling evidence that implicit...

  • Reinstating salience effects over time: the influence of stimulus changes on visual selection behavior over a sequence of eye movements.
    Siebold, Alisha; Donk, Mieke // Attention, Perception & Psychophysics; Aug2014, Vol. 76 Issue 6, p1655 

    Recently, we showed that salience affects initial saccades only in a static stimulus environment; subsequent saccades were unaffected by salience but, instead, were directed in line with task requirements (Siebold, van Zoest, & Donk, PLoS ONE 6(9): e23552, ). Yet multiple studies have shown that...

  • Pre-Saccadic Shifts of Visual Attention.
    Siebold, Alisha; Donk, Mieke // PLoS ONE; Sep2012, Vol. 7 Issue 9, Special section p1 

    The locations of visual objects to which we attend are initially mapped in a retinotopic frame of reference. Because each saccade results in a shift of images on the retina, however, the retinotopic mapping of spatial attention must be updated around the time of each eye movement. Mathôt and...
