Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Visual perception

Background:

  • Humans and non-humans can rapidly estimate quantities.
  • The role of attention in numerical estimation is not fully understood.
  • Visual attention has spatial and object-based modes.

Purpose of the Study:

  • To investigate if spatial and object-based attention enhance number estimation.
  • To determine if attentional cues improve numerical representation accuracy and precision.

Main Methods:

  • Participants performed number estimation tasks with and without attentional cues.
  • Cues directed attention to specific spatial locations or objects.
  • Judgments of accuracy and precision were measured.

Main Results:

  • Enumeration was faster, more precise, and more accurate at cued locations compared to uncued locations.
  • Similar benefits were observed when attention was cued to specific objects.
  • Attentional engagement improved numerical representation.

Conclusions:

  • Visual attention, both spatial and object-based, enhances numerical estimation.
  • Active attention spread within a cued object improves number representation.
  • Numerical estimation, like other perceptual tasks, benefits from attentional focus.
