The Timecourse of Sentence Processing in the Brain
2015
This chapter discusses the current state of the art with regard to the timecourse of sentence processing in the brain. It outlines the challenges associated with studying timecourse information at the sentence level from a neurobiological perspective and describes competing theoretical and empirical perspectives in this domain. In addition to drawing on findings from neurophysiological methods (electroencephalography [EEG]; magnetoencephalography [MEG]), insights from eye movement measures during natural reading are also taken into account. The chapter concludes that while we are currently unable to make absolute claims about the timecourse of sentence processing from a neurobiological pers…
Comparison of Attention Behaviour Across User Sets through Automatic Identification of Common Areas of Interest
2020
Eye tracking is used to analyze and compare user behaviour within numerous domains, but long duration eye tracking experiments across multiple users generate millions of eye gaze samples, making th ...
Les compléments neurophysiologiques du diagnostic
2009
Les recherches presentees mettent en evidence des relations entre anomalies comportementales et cognitives et dysfonctionnements cerebraux sous-jacents a partir de methodes d'exploration electrophysiologique non invasives (electroencephalogramme, potentiels evoques auditifs). Trois types de troubles sont etudies : les troubles du sommeil, l'intolerance au changement et l'exploration visuelle atypique des visages humains. La complementarite des approches cliniques et neurophysiologiques est cruciale aux etapes du diagnostic fonctionnel, de l'intervention therapeutique et educative.
Associations between neonatal cry acoustics and visual attention during the first year
2019
It has been suggested that early cry parameters are connected to later cognitive abilities. The present study is the first to investigate whether the acoustic features of infant cry are associated with cognitive development already during the first year, as measured by oculomotor orienting and attention disengagement. Cry sounds for acoustic analyses (fundamental frequency; F0) were recorded in two neonatal cohorts at the age of 0–8 days (Tampere, Finland) or at 6 weeks (Cape Town, South Africa). Eye tracking was used to measure oculomotor orienting to peripheral visual stimuli and attention disengagement from central stimuli at 8 months (Tampere) or at 6 months (Cape Town) of age. Only a m…
Effects of reading proficiency and of base and whole-word frequency on reading noun- and verb-derived words: An eye-tracking study in Italian primary…
2018
The aim of this study is to assess the role of readers’ proficiency and of the base-word distributional properties on eye-movement behavior. Sixty-two typically developing children, attending 3rd, 4th, and 5th grade, were asked to read derived words in a sentence context. Target words were nouns derived from noun bases (e.g., umorista, ‘humorist’), which in Italian are shared by few derived words, and nouns derived from verb bases (e.g., punizione, ‘punishment’), which are shared by about 50 different inflected forms and several derived words. Data shows that base and word frequency affected first-fixation duration for nouns derived from noun bases, but in an opposite way: base frequency ha…
How Our Gaze Reacts to Another Person’s Tears? Experimental Insights Into Eye Tracking Technology
2020
Crying is an ubiquitous human behavior through which an emotion is expressed on the face together with visible tears and constitutes a slippery riddle for researchers. To provide an answer to the question “How our gaze reacts to another person’s tears?,” we made use of eye tracking technology to study a series of visual stimuli. By presenting an illustrative example through an experimental setting specifically designed to study the “tearing effect,” the present work aims to offer methodological insight on how to use eye-tracking technology to study non-verbal cues. A sample of 30 healthy young women with normal visual acuity performed a within-subjects task in which they evaluated images of…
A Multi-Scale Colour and Keypoint Density-Based Approach for Visual Saliency Detection
2020
In the first seconds of observation of an image, several visual attention processes are involved in the identification of the visual targets that pop-out from the scene to our eyes. Saliency is the quality that makes certain regions of an image stand out from the visual field and grab our attention. Saliency detection models, inspired by visual cortex mechanisms, employ both colour and luminance features. Furthermore, both locations of pixels and presence of objects influence the Visual Attention processes. In this paper, we propose a new saliency method based on the combination of the distribution of interest points in the image with multiscale analysis, a centre bias module and a machine …
Visual-manual in-car tasks decomposed: text entry and kinetic scrolling as the main sources of visual distraction
2013
Distraction effects of in-car tasks with a touch screen based navigation system user interface were studied in a driving simulator experiment with eye tracking. The focus was to examine which particular in-car task components visually distract drivers the most. The results indicate that all of the visual-manual in-car tasks led to increased levels of experienced demands and to lower driving speeds. The most significant finding was that text entry and kinetic scrolling of lists were the main sources of visual distraction whereas simple selection tasks with familiar target locations led to least severe distraction effects.
Did the three little pigs frighten the wolf? How deaf readers use lexical and syntactic cues to comprehend sentences
2020
Abstract Background The ways in which students with deafness process syntactic and semantic cues while reading sentences are unclear. While some studies have supported the preference for semantic cues, others have not. Aim To examine differences in the processing of syntactic versus semantic cues during sentence reading among students who are deaf or hard of hearing (DHH). Method Twenty DHH students (mean age = 12.48 years) and 20 chronologically age-matched students with typical hearing (TH) were asked to read sentences written in Spanish with different grammatical structures and to choose the picture that best matched the sentences’ meaning while their eye movements were being registered.…
Pictorial content, sequence of conflicting online reviews and consumer decision-making: the stimulus-organism-response model revisited
2020
Abstract Conflicting online reviews challenge the consumer’s decision-making processes. Furthermore, increase in visual content, both positive and negative, adds complexity. This study analyses conflicting online reviews based on text and photos using automatic processing patterns and conscious perceptions. The study is built on the stimulus-organism-response model revisited by Jacoby (2002), and captures nonlinear eye-tracking data and a questionnaire. A fsQCA analysis suggests that the order of the positive and negative stimuli strongly influence the way respondents perceive the overall meaning of a sequence of online reviews, supporting primacy-recency effects. In addition, the visualiza…
