Tendency of Experiment 1A participants to match experimenter's means of operating puzzle object mechanisms

Object: Mechanism	Experimenter's means of operation (variation 1/variation 2)	Children matching†	χ2 (df = 1)‡
Puzzle Box: Irrelevant	Push bolt/pull bolt	33%/94%	14.6**
Puzzle Box: Relevant	Remove plug/slide frame	94%/75%	2.7
Cage: Irrelevant	Side handle/top handle	88%/22%	7.2*
Cage: Relevant	Unscrew cap/remove spindle	90%/83%	0.3
Dome: Irrelevant	Pull handle/pull ball	91%/7%	20.6**
Dome: Relevant	Rotate arm/flip up arm	90%/94%	0.3

**, P < 0.001;

*, P < 0.01. All values are two-tailed.

^†Of the participants who saw the experimenter use a given means of operation, the percentage that used that means themselves.

^‡For each mechanism, tests whether children matched one means of operation significantly more than the other.
