In Experiment 3, where the monetary reward was made dependent on accuracy in performance, we found that the rate of illusion-based report of the illusory double-flash was reduced by feedback.
Frequency Doubling Technology (FDT) perimetry employs stimulus fields not dissimilar to those employed in the present study though the grating pattern is phase modulated at a high temporal frequency to produce an illusory doubling of the spatial frequency [ 38].
Moreover, the feedback training effect seemed to disappear once the participants were no longer provided with feedback suggesting a short-lived refinement of discrimination between illusory and physical double flashes rather than vanishing of the illusory percept.
Jews visit places like this to feel at home abroad, but it's all quite illusory; the Jewish population of Cochin doubles or trebles whenever a ship like ours docks there.
The bursting of the stockmarket bubble showed that their pursuit of safe, double-digit real returns was illusory; Enronitis showed that there is no substitute for constant scrutiny and questioning.
Some illusions can be elicited reliably and constant in time (e.g. Kanisza triangle), whereas for other illusions trial-by-trial variability between veridical and illusory perception has been reported (e.g. double-flash illusion [34]).
It's a cautionary tale about the illusory nature of false celebrity, but it serves the double function of commenting on itself.
The best response to this problem probably doesn't involve doubling down on a quest for an illusory neutrality.
Besides double imagery Dali was interested in more complicated illusory strategies, like anamorphosis, an elongated distortion that looks normal only when viewed from a certain perspective.
