The main application scenario for wearable sensors involves the generation of data and monitoring metrics. fNIRS (functional near-infrared spectroscopy) allows the nonintrusive monitoring of human visual perception. The quantification of visual perception by fNIRS facilitates applications in engineering-related fields.…

What is fundamental in vision has been discussed for millennia. For philosophical realists and the physiological approach to vision, the objects of the outer world are truly given, and failures to perceive objects properly, such as in illusions, are just sporadic misperceptions. The goal is to replace the subjectivity…

'Christian Agrillo' 'Simone Cutini' 'Gianluca Campana' 'Luca Battaglini'] For two centuries, visual illusions have attracted the attention of neurobiologists and comparative psychologists, given the possibility of investigating the complexity of perceptual mechanisms by using relatively simple patterns. Animal models…

Since Kepler and Descartes in the early-1600s, vision science has been committed to a triangulation model of stereo vision. But in the early-1800s, we realized that disparities are responsible for stereo vision. And we have spent the past 200 years trying to shoe-horn disparities back into the triangulation account.…

The aims of this paper are twofold: first, to discuss and analyze the concept of binocular disparity and second, to contrast the traditional “air theory” of three-dimensional vision with the much older “ground theory,” first suggested by Ibn al-Haytham more than a thousand years ago. The origins of an “air theory” of…

Although subjective conscious experience and introspection have long been considered unscientific and banned from psychology, they are indispensable in scientific practice. These terms are used in scientific contexts today; however, their meaning remains vague, and earlier objections to the distinction between…

In recent decades, the debate on consciousness has been conditioned by the idea of bottom-up emergence, which has influenced scientific research and raised a few obstacles to any attempt to bridge the explanatory gap. The analysis and explanation of vision conducted according to the accredited methodologies of…

James J. Gibson: 40 years later Authors: H. A. Sedgwick, Brian Rogers The principal objective of both the symposium and this Special Issue was to evaluate the legacy of the ideas contained in Gibson's 1979 book. This necessarily implies an evaluation of the idea of “direct” perception and why he rejected the role of…

What is an “illusion”? I would like to argue that (A) there is no coherent and meaningful definition of the word “illusion” and (B) the majority of the things we have previously labelled as “illusions” can be better categorised into three classes of perceptual effects: (i) those that should not be regarded as illusory…

Perception and mental imagery are clearly distinct, yet images and percepts interact, in that imagining common sounds makes it harder to hear concurrent sounds (Ellson, ) and imagining pictures makes it harder to see (Perky, ). Interaction is consistent with fMRI scans showing that the cortical areas responsive to…

This overview discusses the nature of perceptual illusions with particular reference to the theory that illusions represent the operation of a sensory code for which there is no meaningful ground truth against which the illusory percepts can be compared, and therefore there are no illusions as such. This view…

Introduction This study assessed the dimensions and factors underlying visual mental imagery abilities in young healthy participants. A second purpose was to compare the underlying pattern of factors and dimensions in imagery with those in the corresponding perception tasks. Methods We administered 15 tasks to 32…
