Table 1.
Characteristics of the deaf infants.
Fig 1.
The stimuli used in the habituation task.
Object A [left] served as the habituation stimulus for half of the infants and Object B [right] served as the habituation stimulus for the other half. The remaining object served as the novel stimulus.

Descriptive statistics.
Fig 2.
Visual habituation in deaf and hearing infants.
[A] Deaf infants required more trials to reach the habituation criterion and [B] demonstrated lower look-away rates across habituation trials than their age-matched hearing peers. [C] Deaf infants demonstrated a shallower slope on the first four habituation trials. Note that data points after the fourth habituation trial are based on increasingly fewer infants and a different number of infants per group and should thus be interpreted with caution.
