A (partial) explanation for the Müller-Lyer illusion

نویسنده

  • Bence Nanay
چکیده

The Müller-Lyer illusion is one of the best-known and most frequently examined optical illusions. After pointing out that it is unlikely that any one account would give a full explanation for all the features of this illusion, I argue for two claims. First, I aim to point out that an essential component of the Müller-Lyer illusion has something to do with picture perception (just as Gregory initially claimed). Second, I give an account of this essential component of the Müller-Lyer illusion that is not susceptible to the counterexamples and objections Gregory’s inappropriate size constancy scaling theory was susceptible to. The gist of my account is that the Müller-Lyer illusion is explained not by inappropriate size constancy scaling, but by inappropriate shape constancy scaling.

How the Statistical Structure of the Environment Affects Perception of the Müller-Lyer Illusion

Past researchers have attempted to explain the Müller-Lyer illusion through such means as eye movements (Carr, 1935) and isolating parts from the whole (Pressey, 1971). A recent explanation is that observers are sensitive to statistical regularities within the environment (Howe & Purves, 2005a). Certain configurations of lines appear more often than others within the environment, and this accou...

The role of context in Müller-Lyer illusion: The case of negative Müller-Lyer illusion

The majority of optical illusions are the result of the specific context manipulation of the critical part of the stimuli. There are different examples of how context distorts figures in a way that they might seem different in size, shape, or shade. In the particular case of the Müller-Lyer (ML) illusion, the critical part of the stimulus is the central line (shaft), while the fins represent th...

Pointing and Antipointing in Müller Lyer Figures

It has been suggested that goal-directed actions performed under full vision are immune to certain visual illusions, while movements relying on perception-based visual information are deceived by them (Milner & Goodale, 1995). Consequently, pointing movements should be deceived by visual illusions when a delay is introduced (memory demands) or when antipointing (spatial imagery) is required. In...

Susceptibility to the Müller-Lyer Illusion, Theory- Neutral Observation, and the Diachronic Penetrability of the Visual Input System

Jerry Fodor has consistently cited the persistence of illusions – especially the Müller-Lyer illusion -as a principal form of evidence for the informational encapsulation of modular input systems. Fodor proposed that these modules’ stereotypical deliverances about how the world appears could serve as a theory-neutral observational foundation for (scientific) knowledge. For a variety of reasons ...
