title: Motion-based detection by 14-week-old infants.
abstract: Three experiments using standing wave stimuli with 14-week-old human infants are reported. Two competing hypotheses regarding the detection of these standing wave line stimuli were tested in these studies. Amplitude-based (positional) detection was contrasted with speed-based (motion) detection. Temporal oscillation frequencies of 0.15, 0.30, 0.60 and 1.20 Hz were used. The detectability of a standing wave of fixed amplitude was influenced significantly by the temporal frequency of the oscillation. By inference, the results of the three experiments supported the motion-based detection hypothesis.
