Data for: Alternative spin on phylogenetically inherited spatial reference frames

Each child played two rule-guessing-coin-retrieving games in which s/he was shown where a coin is hidden underneath one of three cups as a clue for choosing the parallel hidden coin from another set of three cups at a second table. To move between tables, the child must turn 180 degrees. With that turn, what was to the child's left and right changes, but what was to their north and the south remained the same. For one game (12 trials), the clues were always consistent with the environmental (north/south) coordinates: A coin at the north cup at Table 1 meant a coin was to be found at the north
cup at Table 2. For another game (12 trials), the clue was always consistent with the children’s left/right: A coin at the left cup at Table 1 meant a coin was to be found at the left cup at Table 2. We varied the table distance, placement of cups, and recorded whether children chose the correct cup on each trial. We asked whether children found more coins for the allocentric/environment rule or more coins for the egocentric rule to assess which relation (allocentric or egocentric) is more salient.
