Tutorial 5: Perception, Knowledge and action

Activity 1

• Now imagine that during the test (dishabituation) phase the baby showed no recovery of interest to the novel utem. That is the length of their fixation to the novel item was the same as at the end of habituation to the familiar item. What could you conclude from this pattern? Try and generate at least two different interpretations.

• same shape

• same colour

• seen the object before → experimental error

• tired but not very long

• no complexity or to complex

• novel object that did not catch their attention

Activity 2

• young infants can tell the difference between scrambled and unscrambled faces they can also tell the difference between a photo of a face the right way up and the same face presented upside down. Why do you think this might be?

  • discriminating between faces

  • the shape of th face and the

  • size constancy

  • shape constancy

  • ethologist

    • perceptual system is influenced by the environment

  • empiricist

    • the environment around us shapes how we view people so not seeing unscrambled faces would allow them to know that that is incorrect

    • environment is rich with people around

  • Nativist

    • born with the ability to recognise faces to help with survival

  • Cognitivist

    • mental processes

    • more inclined to see faces

• what kids of everyday experiences do you think would stimulate infants understanding of object constancies

  • seeing objects at different distances and angles to understand its the same shape and size no matter the distance

  • size and shape constancy

  • playing

  • movement

    • objects, parents, infants themselves

  • provide cues
