... target interception visual illusions Abstract ‘Dazzle coloration’ describes a wide variety of high-contrast patterns allegedly providing protection against attack during motion. Previous research falls into three broad groups. First, studies using humans demonstrate that certain surface patterns can...

... [email protected] Given the large variety of ecological and anatomical differences in animal species, it is perhaps unsurprising that species differ in their perceptions of visual illusions. For example, chimpanzees ( Parrish and Beran 2014 ) and bearded dragons ( Santacà et al. 2019 ) demonstrated a human...

... visual hallucinations while being observed by clinicians. Therefore, instruments to detect visual hallucinations directly from patients are needed. Pareidolias, which are complex visual illusions involving ambiguous forms that are perceived as meaningful objects, are analogous to visual hallucinations...

..., using methods such as contrast sensitivity. Higher, integrative stages of functioning, such as susceptibility to visual illusions, have been evaluated less extensively. For example, patients show increased susceptibility to (ie, are more easily affected by) the Muller-Lyer illusion but decreased...

... be the unintended result of how the mind evolved to use heuristics and reach conclusions based on scarce and incomplete data. Thus, we present visual illusions as a parallel to the type of fast and frugal cognitive bias that underlies pseudoscientific belief. In particular, we focus on the causal illusion, which...

...There have long been psychologists who have asserted that sensation is not measurable. This second chapter looks at philosophical objections to the idea and empirical findings that bear on the issue. These findings include visual illusions, particularly the perception of features that are simply...

...Oxford University Press Visual hallucinations are perceptions that occur in the absence of a corresponding external visual stimulus, whereas visual illusions are misinterpretations of an external visual stimulus. Migraine visual aura is a common cause of transient visual hallucinations. Similar...

... compares amodal completion and the perception of visual illusions in birds and primates. Amodal completion concerns the perception of partly occluded figures. Visual illusions, in theory, represent cases in which perceptual systems that are adaptively suited to some situations may suffer in other...

...This chapter presents a review of the evidence supporting the notion that motor responses may resist visual illusions. It asks the question of whether actions will be affected by illusions. The review is selective, as dictated by space constraints, and highly critical because the interpretation...

... the world in accord with physical reality but are sometimes fooled in special circumstances that give rise to discrepancies between reality and what we perceive (visual illusions). Evidence accumulated over the past decade, however, indicates that all visual perceptions are at odds...

...Visual illusions cut across academic divides and popular interests: on the one hand, illusions provide entertainment as curious tricks of the eye; on the other hand, scientific research related to illusory phenomena has given generations of scientists and artists deep insights into the brain...

.... Finally, some well-known visual illusions are shown and the perceptions are explained by means of generative, information integrating, perceptual processes, which in all cases combine top-down prior knowledge and expectations about objects and environments with the available, bottom-up visual information...

...This chapter provides a discussion on illusions in neglect. The data shows that the pathological bias producing the line-length effect applies not only to physical but also to perceived represented length. In general, the available empirical evidence concerning the processing of visual illusions...
