PEPI, The Dalmatian in Motion

The picture of PEPI is hidden in the background except when moving. Thus response to it means that the infant/child can perceive an image in motion. A picture of a dog interests most children, especially because it is first hidden and then suddenly appears. The test shows how well the child can

1. fixate the central fixation target,
2. make a quick saccad, when the dog swiftly appears in one of the corners, and
3. use following movement across the screen.

There are 4 sequencies to allow observations in both sides of the visual field.

To start, press to move the image from right up to left down to move the image from right down to left up to move the image from left down to right up to move the image from left up to right down. To quit, press Ctrl-Q.
