Experiment 2 procedure and alignment sensitivity for static forms.

A) Depiction of procedure for Experiment 2. Observers viewed two second presentations of either smooth motion, scrambled motion, or of a static waveform. This was followed by a static inter-stimulus-interval (ISI), after which two adjacent probes were presented that contained waveforms either aligned or misaligned with the central test waveform. Observers were required to complete a forced choice task, indicating if the probe and central waveforms were aligned or misaligned. B) Alignment sensitivities (d′) for 11 observers. Error bars depict +/− 1 s.e.m.
