Summary

A moving frame shifts visual stimuli, creating classic illusions like the Müller-Lyer and Poggendorff illusions. This position shift occurs before the brain processes these visual illusions.

Area of Science:

Visual perception
Cognitive neuroscience
Psychophysics

Background:

Moving frames can alter perceived stimulus locations.
This phenomenon can induce visual illusions from neutral stimuli.

Purpose of the Study:

To investigate if frame-induced position shifts precede illusion formation.
To determine the temporal order of visual displacement and illusion processing.

Main Methods:

Presenting flashed elements within a moving frame.
Analyzing the creation of Müller-Lyer and Poggendorff illusions.
Comparing illusion onset with frame-induced position shift emergence.

Main Results:

A moving frame rearranged flashed elements into illusory forms.
The frame-induced offset of chevrons created a Müller-Lyer illusion.
The frame-induced offset of line segments created a Poggendorff illusion.

Conclusions:

Frame-induced position shifts must precede the neural sites of Müller-Lyer and Poggendorff illusions.
Visual displacement by a moving frame is an early visual process.
