Bertamini Lab

These animations are provided to complement the following manuscript:
Bertamini, M. & Hulleman, J. (2006). Amodal completion and visual holes (static and moving). Acta Psychologica, 123, 55-72.

In this paper we discuss situations in which motion parallax and binocular parallax are in conflict. In the animations we could not show binocular parallax (it would be hard for you to see stereograms on the web), therefore we colour-coded the frontal plane as red.

HBF+

Background texture stationary. Foreground texture moving. Natural event where the surface-with-hole moves in front of stationary background. Hole does not change position on foreground surface. Texture visible through hole changes.

HB+F+

Background texture moving. Foreground texture moving. Natural event where the surface-with-hole moves in front of a moving background (together). Hole does not change position on foreground surface. Texture visible through hole does not change

OBF+

Background texture stationary. Foreground texture moving. Natural event where object [with unchanging texture] moves in front of stationary background

OB+F+

Background texture moving. Foreground texture moving. Natural event where the object [with unchanging texture] moves in front of a moving background (together)

HBF

Background texture stationary. Foreground texture stationary. Strange event where the hole changes position on the surface-with-hole in front of a stationary background. Foreground changes shape. Texture visible through hole changes.

HB+F

Background texture moving. Foreground texture stationary. Strange event where the hole changes position on the surface-with-hole in front of a moving background. Foreground changes shape (cue conflict - disparity vs accretion/ deletion). Texture visible through hole does not change

OBF

Background texture stationary. Foreground texture stationary. Strange event where the object changes texture while moving.

OB+F

Background texture moving. Foreground texture stationary. Strange event where the object changes texture while moving, (cue conflict - disparity versus accretion/deletion).
