Our stimuli depicted camouflaged animals in their natural habitats.
In the fourth experiment, we directly assessed the fusional range for our stimuli.
To simulate the reduced sensitivity to high spatial frequencies, on some trials we blurred our stimuli.
In addition, we directly measured how fusion was affected by the magnitude of disparity for our stimuli.
Our stimuli contained a target set of dots, moving at a uniform speed, superimposed on a "mixed-speed" distractor set.
The large disparities in our stimuli, up to a maximum value of 2.5 degrees, are beyond the "depth budget" or "depth bracket" advised in stereoscopic applications.
Our stimuli consisted of arrays of randomly positioned circles, presented on two planes in depth defined by binocular disparity and occlusion.
To isolate the influence of binocular cues and reduce the effects of conflicts with pictorial cues, we used simple random element stereograms as our stimuli.
In our stimuli set, we only included images with a single localisable mass, which may have increased the likelihood of finding localisation information.
Perhaps technology has even increased our stimuli and desire to reach out, to travel, to discover, to dream big, to be divas, presidents and astronauts, but reality is very different from social media, movies and glossy magazines of top models.
Thus, all of our stimuli induced a strong inversion-effect.
