“…This research stems from pioneering works on the Müller-Lyer illusion induced through mental images (Berbaum & Chung, 1981;Ohkuma, 1986;Watters & Scott, 1989). Despite the abundance of recent work on the Müller-Lyer illusion (Costa et al, 2021;Cretenoud et al, 2020;Schwarz & Reike, 2020;Zhang et al, 2020), no studies are found on the induction of the illusion by mental imagery and few are concerned with the influence of the wings length on the magnitude of the illusion. Also, fine arts students are of the utmost interest because they have certain personality and perceptual traits that seem to be related to resistance to the Müller-Lyer illusion (see, Pérez-Fabello et al, 2016, 2018Pérez-Fabello & Campos, 2011a, b, c, 2022Zhang et al, 2017).…”

“…Many aspects of the Müller-Lyer illusion have already been studied. As stimuli definers, researchers have considered geometric and physical parameters (Cretenoud et al, 2020;DeLucia, 1993;Dragoi & Lockhead, 1999;Saccone & Chouinard, 2019;Schwarz & Reike, 2020;Zhang et al, 2020), neurophysiological factors (de Brouwer et al, 2015;Qiu et al, 2008;Tabei et al, 2015;Weidner et al, 2010;Zhang et al, 2013), the magnitude of the illusion as a function of age (Bondarko & Semenov, 2009;Brosvic et al, 2002), the influence of sociocultural backgrounds (McCauley & Henrich, 2006;Phillips, 2019), the influence of the illusion on interpersonal distance (Brunce et al, 2021), the illusion as related to personality traits (Zhang et al, 2017) and clinical disorders (Chouinard et al, 2013;Costa et al, 2021). Furthermore, there is a copious number of recent studies that deal with the experience of the illusion in a wide variety of animals (Costa et al, 2021;Schwarz & Reike, 2020).…”

Previous studies have pointed to a link between visual perception and mental imagery. The present experiment focuses on one of the best-known illusions, the Müller-Lyer illusion, now reproduced under conditions of real perception and by means of imagery. To that purpose, a tailored ad-hoc set of combined figures was presented to a total of 161 fine art students (M age = 20,34, SD = 1,75) who individually worked with two different variations of the Müller-Lyer figures which consisted of a 10 mm long shaft and two fins set at an angle of 30º, being 15 mm long in one instance and 45 mm long in the other. In small groups, participants also completed an image control questionnaire. Results yielded that the longer the oblique lines, the larger the magnitude of the illusion both in the situation of real perception and in the imaginary situation. Also, the magnitude of the illusion augmented in the situation of perception in contrast to the imaginary situation, both with 15 mm long fins and with those of 45 mm. However, no significant differences were found in the magnitude of the illusion between high and low individuals in image control, although interactions between image control and other variables were indeed significant. The consistency of the outcome is a step forward in the study of illusions through mental images and opens the door to new lines of research that could involve innovative methods of analysis, different versions of the illusion and wider groups of participants.

“…While some empirical research has shown this to be the case ( 20 , 22 , 37 ), others, more in line with our results, have found both starting point and drift criterion shifts in base rate ( 38 ) and in payoff manipulations ( 20 ). On the other hand, the Müller-Lyer illusion has been associated with drift rate effects ( 39 ) with similar findings for manipulations aimed at affecting perception such as when manipulating the length of a reference line ( 22 ). It is worth noting that these apparent mixed results are not limited to payoff and base rate manipulations.…”

To survive, organisms constantly make decisions to avoid danger and maximize rewards in information-rich environments. As a result, decisions about sensory input are not only driven by sensory information but also by other factors, such as the expected rewards of a decision (known as the payoff matrix) or by information about temporal regularities in the environment (known as cognitive priors or predictions). However, it is unknown to what extent these different types of information affect subjective experience or whether they merely result in nonperceptual response criterion shifts. To investigate this question, we used three carefully matched manipulations that typically result in behavioral shifts in decision criteria: a visual illusion (Müller-Lyer condition), a punishment scheme (payoff condition), and a change in the ratio of relevant stimuli (base rate condition). To gauge shifts in subjective experience, we introduce a task in which participants not only make decisions about what they have just seen but are also asked to reproduce their experience of a target stimulus. Using Bayesian ordinal modeling, we show that each of these three manipulations affects the decision criterion as intended but that the visual illusion uniquely affects sensory experience as measured by reproduction. In a series of follow-up experiments, we use computational modeling to show that although the visual illusion results in a distinct drift-diffusion (DDM) parameter profile relative to nonsensory manipulations, reliance on DDM parameter estimates alone is not sufficient to ascertain whether a given manipulation is perceptual or nonperceptual.

As a result, decisions about sensory input are not only driven by sensory information, but also by other factors, such as the expected rewards of a decision (known as the payoff matrix) or by information about temporal regularities in the environment (known as cognitive priors or predictions). However, it is unknown to what extent these different types of information affect subjective experience, or whether they merely result in non-perceptual response criterion shifts. To investigate this question, we used three carefully matched manipulations that typically result in behavioral shifts in decision criteria: a visual illusion (Müller-Lyer condition), a punishment scheme (payoff condition), and a change in the ratio of relevant stimuli (base rate condition). To gauge shifts in subjective experience, we introduce a novel task in which participants not only make decisions about what they have just seen, but are also asked to reproduce their experience of a target stimulus. Using Bayesian ordinal modeling, we show that each of these three manipulations affects decision criterion as intended, but that the visual illusion uniquely affects sensory experience as measured by reproduction.
