The ability of typically developing 2-3 year olds to infer the control mechanism for eye-gaze technology and the impact of causal language instruction.

Although 2-3 years in the study could make use of eye-gaze technology with support, this study found no evidence that these children could infer the causal mechanisms of control independently or intuitively. The lack of spatial contiguity and the comparative lack of feedback from eye-gaze devices are discussed as possible contributory factors.
