The Fixation Duration in each condition and the concentrations of PCB congeners.

<p>M: Mean, SD: Standard Deviation N.D.: None Detected.</p><p>The fixation durations are rounded at the first decimal place.</p

Correlation Coefficients between the concentrations of PCB congeners and KIDS Development Indices.

*<p><i>p</i><.05.</p

Examples of point-light display and stimulus display.

<p>Panel a) The schematic depiction of the concept of point-light display. The bodily motion of a human walker is represented as a constellation of moving white dots attached to each joint. Panel b) An example of the stimulus display in preferential looking experiment.</p
