o 40% tongue protrusion vs. 10% mouth opening when model protrudes tongue o Replication issues Info unreliable until 9 months of age o Deferred imitation Collie and Hayne Someone presses button.. cool thing happens… baby leaves and comes back after a certain time.. presses button o Memory Habituation/dishabituation research Piaget claims that babies don’t have memory Rovee-Collier mobile experiment Showed memory in three month olds Babies laid under mobile- control group Experiment group had a string on their leg and if they kicked, the mobile would move Kick rate of the experimental group doubled, while the control group stayed the same Babies left and came back later- put experimental group in crib with no string, experimental group ends up kicking a lot more than control group Implies they do have memory o Object permanence Critiques that Piaget underestimate babies’ understanding of object permanence A-not-B task- reaching for point A but looking at point B- can’t change the action they make- this is called response inhibition Motor search> intentionality Appeared to be an attempt to motor search… baby reaching for blanket, but did not have enough motor skills to pull it away Baillargeon’s Impossible Events 4 ½ months – habituated infants to a fan at 180 degrees
