over somatosensory modalities. And the interaction of vision and proprioception has been studied recently in animals and humans (Graziano 1999; Fink et al 1999; Farne et al 2000). Ramachandran and colleagues had the clever insight to appreciate and show that visual input of the reflection of the intact arm seen in a mirror could be used to mobilize previously immobile phantom limbs. Subsequent studies have confirmed the findings of Ramachandran and colleagues (1995) in some phantom-limb… 

Interaction of Vision and Movement via a Mirror

This observation may help in understanding how visual feedback via a mirror may be beneficial for rehabilitation of some patients with movement deficits secondary to certain neurologic conditions, and illustrates that the traditional division of neural processes into sensory input and motor output is somewhat arbitrary.

Blinded by magic: eye-movements reveal the misdirection of attention

An eye-tracking experiment showed that when participants watched several “practice” videos without any moving coin, they became far more likely to detect the coin in the critical trial, consistent with perceptual load theory.

Social Misdirection Fails to Enhance a Magic Illusion

It is determined that subjects required multiple trials to effectively distinguish real from simulated tosses; thus the illusion was resilient to repeated viewing and therefore social misdirection is redundant and possibly detracting to this very robust sleight-of-hand illusion.

A Study of Behavioural and Neural Signatures of Perceptual and Cognitive Illusions Induced by Magic Effects

In two experiments, showing behavioural and evoked responses of subjects while watching an oddball sequence of continues, unedited videos of a magic trick known as Chop-Cup, it was found that, on the one hand, subjects’ behavioural responses were strongly biased by the magic trick, and on the other, that the neural responses were modulated by the odd ball sequence of stimulus presentation, as expected.

Using magic to reconcile inattentional blindness and attentional misdirection

Kuhn, Tatler, Findlay, & Cole (2008) Recently, Memmert [2010, Consciousness & Cognition, 19, 1097-1101] argued for an empirical dissociation between inattentional blindness (IB) and attentional

Perception of the visual environment

This chapter considers what has been learnt about targeting the eyes in a range of experimental paradigms, from simple stimuli arrays of only a few isolated targets, to complex arrays and photographs of real environments, and finally to natural task settings.

Using Magic as a Vehicle to Elucidate Attention

Attention, the awareness and selection of elements in our physical or mental environments, is a central concept in neuroscience. Michael I Posner and colleagues have proposed a three-network model of

Attentional focus versus diffuse attention

How toddlers’ attention is distributed in the visual field during a magic trick was examined using three expectation conditions. Results showed that 2.5-year-old children assigned to the condition

Microsaccades reflect the dynamics of misdirected attention in magic

The combined results indicate that microsaccades may be a useful metric of covert attentional processes in applied and ecologically valid settings.

Get real! Resolving the debate about equivalent social stimuli

Gaze and arrow studies of spatial orienting have shown that eyes and arrows produce nearly identical effects on shifts of spatial attention. This has led some researchers to suggest that the human



Visual stability across saccades while viewing complex pictures.

Evidence suggests that subjects' detection of image changes primarily involves the use of local information in the region of the eyes' landing position, and a saccade target theory of visual stability is proposed.

Gorillas in Our Midst: Sustained Inattentional Blindness for Dynamic Events

A new study builds on classic studies of divided visual attention to examine inattentional blindness for complex objects and events in dynamic scenes and suggests that the likelihood of noticing an unexpected object depends on the similarity of that object to other objects in the display and on how difficult the priming monitoring task is.

TO SEE OR NOT TO SEE: The Need for Attention to Perceive Changes in Scenes

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between

Failure to detect changes to attended objects in motion pictures

Our intuition that we richly represent the visual details of our environment is illusory. When viewing a scene, we seem to use detailed representations of object properties and interobject relations

The Role of Fixation Position in Detecting Scene Changes Across Saccades

Target objects presented within color images of naturalistic scenes were deleted or rotated during a saccade to or from the target object or to a control region of the scene. Despite instructions to

Failure to detect changes to people during a real-world interaction

Recent research on change detection has documented surprising failures to detect visual changes occurring between views of a scene, suggesting the possibility that visual representations contain few

What you see is what you set: sustained inattentional blindness and the capture of awareness.

The authors conclude that many--but not all--aspects of attention capture apply to inattentional blindness but that these 2 classes of phenomena remain importantly distinct.

On the Failure to Detect Changes in Scenes Across Brief Interruptions

When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: The changes become extremely difficult to notice,

Eye-head coordination during driving

A portable eye movement camera is described which allows eye, head and gaze movements to be determined during driving and other activities to accurately predict eye and head movements at intersections.

Where we look when we steer

It is found that drivers rely particularly on the 'tangent point' on the inside of each curve, seeking this point 1–2 s before each bend and returning to it throughout the bend, and this work examines the way this information is used.
