Document Summary
Weaknesses of piaget"s theory: infants and young children"s abilities: underestimated, adolescents" and adults" abilities: over-estimated, mechanisms difficult to define and measure: too vague, variability in children"s progress: shifting stages is not uniform, The infants in the experimental group look at the box more than the control group and view it as novel, it causes surprise: results: 4 month olds- experimental group consistently gazed at the critical event longer. 3 month olds- initial analysis of data: inconsistent. 3 mountain, 3 non mountains, 8 different objects. Also provided a rotating model they could use instead of a picture method: results: 4 year olds- 67%, 85%, 95% The errors were randomly distributed among the other perspectives (not their own) The success in this task is attributed to the rotating model! 3 1/2 year olds- 42%, 80%, 79: errors were equally distributed among other perspectives (not their own, conclusion: visual discriminability can enhance performance.
