Attention modulates spatio-temporal grouping

Michael Herzog

Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resour ...

Surface Construction by a 2-D Differentiation-Integration Process: A Neurocomputational Model for Perceived Border Ownership, Depth, and Lightness in Kanizsa Figures

Christoph Strecha

Human visual perception is a fundamentally relational process: Lightness perception depends on luminance ratios, and depth perception depends on occlusion (difference of depth) cues. Neurons in low-level visual cortex are sensitive to the difference (but n ...

Application of Tactile Perception Enhancement

Sylvain Cardin

Surrounding environment is mainly perceived through sight and hearing. Our sense of touch is mostly dedicated to explore the surface of objects using hands and fingers. Tactile sensitivity of the body skin is rather limited in common life, however this rep ...

Grouping and Gestalt in Visual Contextual Modulation

Bilge Sayim

The perception of a visual stimulus is strongly modulated by surrounding elements. This phenomenon, called contextual modulation, can be exemplary observed in a large number of visual illusions, e.g. in the tilt-illusion where a vertical grating appears ti ...

Capturing lightness between contours

Marcus Leonardus Vergeer

Homogeneously coloured bars may exhibit lightness differences at the intersections. A well-known example is the Hermann grid illusion, where crossing white bars on a black background show dark patches at the crossings. Jung (1973, Handbook of Sensory Physi ...

Three sequential brain activations encode mental transformations of upright and inverted human bodies: a high resolution evoked potential study

Olaf Blanke

Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...

Contextual modulation in human vision

Toni Saarela

The processing and perception of visual stimuli are greatly dependent on the context in which those stimuli are presented. While this is not always (and indeed is probably not "supposed" to be) evident when viewing real-world scenes, the abundance of conte ...

Temporal integration in visual word recognition

Joachim Jean-Marie Forget

When two displays are presented in close temporal succession at the same location, how does the brain assign them to one versus two conscious percepts? We investigate this issue using a novel reading paradigm in which the odd and even letters of a string a ...

Asynchronous Non-Invasive Brain-Actuated Control of an Intelligent Wheelchair

José del Rocio Millán Ruiz, Eileen Lew Yi Lee

In this paper we present further results of our asynchronous and non-invasive BMI for the continuous control of an intelligent wheelchair. Three subjects participated in two experiments where they steered the wheelchair spontaneously, without any external ...

How the mind constitutes itself through perceptual learning

Michael Herzog

Most theories of perception assume a rigid relationship between objects of the physical world and the corresponding mental representations. We show by a priori reasoning that this assumption is not fulfilled. We claim instead that all object-representation ...
