A two-stage model of decision making

Michael Herzog, Adrien Christophe Doerig, Leila Drissi Daoudi - Kleinbauer

The drift diffusion model (Ratcliff, 1978) is widely used to model binary decision-making. In this model, evidence for the two alternatives is integrated over time until it hits a decision boundary leading to a reaction. The drift diffusion model fits many ...

From retinotopic processing to nonretinotopic representation

Marc Michael Lauffs

Encoding of visual information in the brain is retinotopic: Neighboring points in the visual field are mapped onto neighboring photoreceptors in the retina, and these neighborhood relations are maintained in the early stages of cortical processing. However ...

Sparse Pronunciation Codes for Perceptual Phonetic Information Assessment

Hervé Bourlard, Milos Cernak, Afsaneh Asaei, Dhananjay Ram

Speech is a complex signal produced by a highly constrained articulation machinery. Neuro and psycholinguistic theories assert that speech can be decomposed into molecules of structured atoms. Although characterization of the atoms is controversial, the ex ...

Keyword-based Image Color Re-rendering with Semantic Segmentation

Sabine Süsstrunk, Fayez Lahoud, Bin Jin

Keyword-based image color re-rendering is a convenient way to enhance the color of images. Most methods only focus on the color characteristics of the image while ignoring the semantic meaning of different regions. We propose to incorporate semantic inform ...

Multi-modality Sensory Feedback: a pilot study

Huaiqi Huang

The aim of this study is to test the hypotheses that a multi-modality sensory feedback device, incorporating mechanotactile and vibrotactile feedback can increase the subjects’ performance in localization and intensity discrimination.To the best of our kno ...

Spatial filters yield stable features for error-related potentials across conditions

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil, Fumiaki Iwane

Error-related potentials (ErrP) have been increasingly studied in psychophysical experiments as well as for brain-machine interfacing. In the latter case, the generalisation capabilities of ErrP decoders is a crucial element to avoid frequent recalibration ...

Using pot-magnets to enable stable and scalable electromagnetic tactile displays

Herbert Shea, Juan José Zarate

We present the design, fabrication, characterization and psychophysical testing of a scalable haptic display based on electromagnetic (EM) actuators. The display consists of a 4x4 array of taxels, each of which can be in a raised or a lowered position, thu ...

Multisensory simultaneity judgment and proximity to the body

Andrea Serino, Jean-Paul Noel, Marta Lukowska

The integration of information across different sensory modalities is known to be dependent upon the statistical characteristics of the stimuli to be combined. For example, the spatial and temporal proximity of stimuli are important determinants with stimu ...

Thermo-mechanical volume change behaviour of Opalinus Clay

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The paper examines the thermo-mechanical volume change behaviour of Opalinus Clay in relation to different stress conditions and overconsolidation ratio (OCR) values and evaluates the impact of temperature on some hydro-mechanical properties of this materi ...
