Table 1.

3.5- and 5-month-old infants’ mean look durations (in seconds) to the matching and nonmatching body postures and percentage preferences for the matching stimuli in Experiment 1 (both age groups) and Experiment 2 (5-month-olds only).

Orientation	n	Matching [M (SE)]	Nonmatching [M (SE)]	Percent preference [M (SE)]	t^a	p^a
Upright (Experiment 1)
3.5-month-olds	20	6.29 (0.61)	7.25 (0.69)	47.17 (4.55)	−0.62	.54
5-month-olds	16	7.86 (0.63)	5.19 (0.46)	59.52 (3.70)	2.57	.02^*

Inverted (Experiment 2)
5-month-olds	16	6.53 (0.69)	5.99 (0.66)	51.98 (4.51)	0.44	.67

Comparison of mean percentage preference score against the chance level of 50%:

p < .05 (two-tailed).
