Table 1.

Means and standard deviations for visual fixation in seconds for baseline (first two habituation trials), trials to habituation (number of habituation trials to reach criterion), post habituation (two no-change trials following habituation reflecting final interest level), processing time (total number of seconds fixating the habituation events), and test trials as a function of age (2, 3 months) and condition (synchronous audiovisual, unimodal visual, asynchronous audiovisual).

Experiment	Age	Condition	Baseline	Trials to Habituation	Post Habituation	Processing Time	Test
1	2 months	Synchronous Audiovisual	31.58 (11.75)	9.19 (4.52)	9.62 (9.52)	217.71 (82.64)	13.42 (10.45)

1	2 months	Asynchronous Audiovisual	30.55 (10.78)	11.19 (3.35)	5.91 (3.42)	285.17 (142.85)	22.27 (13.12)
2	3 months	Synchronous Audiovisual	46.93 (12.64)	8.06 (2.79)	10.67 (5.15)	298.84 (185.47)	21.90 (14.44)
