Attentional capture by new objects depends on your current focus. When searching for visual onsets, new objects capture attention, but not when searching for color, indicating top-down control.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Attention

Background:

  • Attentional capture by abrupt onsets is influenced by top-down attentional control.
  • The role of top-down control in attentional capture by new perceptual objects remains less understood.

Purpose of the Study:

  • To investigate whether attentional capture by new objects is modulated by top-down attentional control settings.
  • To differentiate capture by abrupt onsets from capture by new object appearance.

Main Methods:

  • A modified spatial cuing task was employed across four experiments.
  • Targets were defined by abrupt onset or color, while distractors involved abrupt brightening or new object appearance.
  • Behavioral evidence of attentional capture was measured.

Main Results:

  • Both onset and new object distractors captured attention when searching for an onset target.
  • No attentional capture was observed for color targets, irrespective of distractor type (new object or not).
  • Rapid recovery from capture did not explain the lack of effects in the color-target condition.

Conclusions:

  • Attentional capture by new perceptual objects is subject to top-down modulation.
  • Attentional control settings significantly influence whether new objects capture attention.
  • This suggests flexible, goal-directed control over visual attention to new stimuli.
