  • Research Question:
    • Two Methods for measuring action anticipation:
      • Online - Eyetracking/predictive gaze during the action
      • Post Hoc - looking time paradigmlooking time paradigm
        A basic paradigm used in developmental psychology to research phenomena in early-childhood, as participants have no means of direct communication. The time a child fixates on a scene is measured an...
        after the action concluded (suggests fulfilled/broken expectations)
    • Do both of these measure the same thing?
  • Method:
    • 9 month old children
    • A scene (similar in spirit to woodwardInfantsSelectivelyEncode1998woodwardInfantsSelectivelyEncode1998

      Used a [[looking tim...
      ) was set up, where a figure would go through a tunnel to chose one of two objects during trial runs, where-after the objects would be switched in the test run
    • During the test run, the anticipatory looking was measured while the figure was in the tunnel. Additionally, the looking time after the figure chose the specific object was captured across two conditions (goes to same location, goes to same object)
  • Result:
    • The children predicted the same-path condition correctly in 72% of the cases, suggesting that anticipatory looking follows path-related expectations
    • The children showed a higher looking time for old-path/new-object condition, suggestion the looking time follows identity-related expectations (?)
  • Discussion:
    • A dissociation exists between those two measures
    • The paper also shows that this dissociation remains for the first 3 years of life (after which both show identity related expectations).
    • The results directly contradict the results shown in cannonInfantsGenerateGoalbased2012cannonInfantsGenerateGoalbased2012
