Toddlers

Area of Science:

  • Cognitive Development
  • Visual Perception
  • Object Permanence

Background:

  • Young children struggle with object search tasks when a barrier partially obscures the object.
  • Adults' object-directed attention is influenced by object boundaries and proximity.
  • Understanding early object representation is key to cognitive development.

Purpose of the Study:

  • To investigate how object boundaries and proximity affect toddlers' search for hidden objects.
  • To explore parallels between toddlers' and adults' object-directed attention.
  • To determine if visible object parts or landmarks better guide toddlers' search.

Main Methods:

  • Four experiments tested toddlers' search for a hidden toy car behind an occluding panel.
  • Varied the visibility and proximity of object parts and barriers.

Related Experiment Videos

  • Measured search performance based on correct object location identification.

    • Main Results:

    • Toddlers performed near ceiling when a visible part was close to the hidden car body.
    • Performance was below ceiling when a visible part was further away.
    • Search was at chance when only a separate barrier was visible.

    Conclusions:

    • Toddlers' hidden object search is significantly influenced by the proximity of visible object parts.
    • Findings suggest early parallels in object representation and attention between toddlers and adults.
    • Object proximity, not landmark proximity, guides toddlers' attention to hidden objects.
