Children and finding tasks

The graph above appears in a post over at Cognitive Daily. Basically, the colored columns for each age group correspond to three different “finding” tasks associated with objects underneath cups. In all three, a reward is hidden under one of two cups, and then the cups are hidden from view while the table rotates 180 degrees (to swap the location of the cups) or 360 degrees (to keep the cups in the same locations). The tasks vary as follows:

  • Colored cups: The cups are the visual indicator that a change has or has not occurred.
  • Left/Right: The cups are the same color, but the table is the visual indicator: half-black and half-white. The cups occupy exactly one color.
  • Top/Bottom: The cups are the same color, and the table is the visual indicator: half-black and half-white. The cups straddle the color division line. If the table is black on top, rotating it 180 degrees means it will be black on the bottom.
To me, the interesting thing is the decrease in performance in the colored cup task: arguably the most basic. I suspect that not enough data was gathered. I’d love to read the article, but not for the $11.95 asking price.
