Processing and representation of ambiguous words in Chinese reading: Evidence from eye movements

2016

In the current study, we used eye tracking to investigate whether senses of polysemous words and meanings of homonymous words are represented and processed similarly or differently in Chinese reading. Readers read sentences containing target words which was either homonymous words or polysemous words. The contexts of text preceding the target words were manipulated to bias the participants toward reading the ambiguous words according to their dominant, subordinate, or neutral meanings. Similarly, disambiguating regions following the target words were also manipulated to favor either the dominant or subordinate meanings of ambiguous words. The results showed that there were similar eye movem…

Korelācija starp acu dominanci un ķermeņa stājas līdzsvaru

2017

Bakalaura darbs ir uzrakstīts angļu valodā uz 34 lapaspusēm, tas satur 21 zīmējumus, 21 atsauces uz literatūras avotiem. Darba mērķis ir novērtēt sensorialās un motorās dominances ietekmi uz ķermeņa līdzsvaru statiskos apstākļos. Salīdzinot abu atvērto acu testus ar aiztaisīto acu testiem var redzēt stipru binokulārās redzes ietekmi uz ķermeņa līdzsvaru. Turpretī nav novērota statistiska atšķirība starp atvērtas dominantās acs ietekmi un atvērtas nedominantās acs ietekmi. Visiem pētījumu dalībniekiem atvērta dominantā acs neuzrādīja lielāku ietekmi uz līdzsvara balansu kā nedominantā acs. Turpretī binokulārās redzes apstākļos līdzsvars uzlabojās, ko var redzēt pēc ticamības elipses lieluma …

Observing animals and humans : dogs target their gaze to the biological information in natural scenes

2020

Background This study examines how dogs observe images of natural scenes containing living creatures (wild animals, dogs and humans) recorded with eye gaze tracking. Because dogs have had limited exposure to wild animals in their lives, we also consider the natural novelty of the wild animal images for the dogs. Methods The eye gaze of dogs was recorded while they viewed natural images containing dogs, humans, and wild animals. Three categories of images were used: naturalistic landscape images containing single humans or animals, full body images containing a single human or an animal, and full body images containing a pair of humans or animals. The gazing behavior of two dog populations,…

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…

A user-friendly control system to easy reconfigure a manufacturing cell

2006

Generic manufacturing enterprises need to interact with an environment characterized by a strong competition. In order to react to the mutable requests of market, control systems should confer to the manufacturing system capabilities for easy modifiability, and this can be achieved by reducing the necessary time to reconfigure the existing system. Following this main requirement, this paper presents a user-friendly control system that pursues three operational goals: - Ability to easy re-program the sequence of operations of the manufacturing equipments of a manufacturing cell; - Reconfigurability of the system, by allowing to add/remove a new/existing component in/from the manufacturing ce…

Three-dimentional tracking of human eye

2003

The study of human movements is the object of numerous searches, among them, the study of the face movements and more particularly the eye kinetics estimate represents an important part. A study realized by artificial vision is presented here. It allows to characterize eye movements in normal shooting condition (mobility of the subject, background lighting). Our approach allows to obtain in a simple way the localization of the iris and the characterization of their movement in the three dimensional shape. The absolute 3D movement of eyeballs and their relative movement with regard to the head are obtained, even if this one are moving.

“You look at it, but will you choose it”: Is there a link between the foods consumers look at and what they ultimately choose in a virtual supermarke…

2022

Most of the studies that showed a link between gaze allocation and consumer's food choices were performed on food products belonging to a same category. However, consumers usually make food choices in more complex environments, between many different products, and different factors can influence their choices. Therefore, our study aimed to understand the link between gaze behavior and food choices in a complex and realistic situation of choice. Participants (n=99) performed a food choice task in a virtual supermarket. They had to choose three food products to create a dish in four scenarios evoking different motivations (focus on health, environment, food pleasure, and daily scenario as con…

Rett syndrome and eye-tracking technology: A brief review

2019

Introduction: Rett Syndrome is a severe, genetically based neurodevelopment disorder caused mostlyby mutations in the MECP2 gene on the X chromosome. One of the supportive criteria for the diagnosis of this syndrome is intense eye gaze with preferential eye fixation on social stimuli and especially on people’s eyes. This pattern of preferential looking has generally been considered a way to make requests and communicate. Materials and methods: In this review we have collected the studies on the use of eye-tracking technology with subjects with Rett Syndrome. The combination of keywords “Rett Syndrome” and “Eye Tracking” was used in a Medline literature search. In order to be included in thi…

Alternative Methoden der Lokaltherapie bei komplizierten periokulären Infektionen – 2 Fallberichte

2017

Hintergrund In der Regel konnen Wunden im Lidbereich mit gangigen Masnahmen der Lidchirurgie und lokaler Antibiose suffizient behandelt werden. An 2 Fallen zeigen wir exemplarisch, dass Verfahren der „2. Wahl“ – wie das biologische Debridement oder mit Unterdruck arbeitende Vakuumverbande – in ausgewahlten Fallen sinnvoll eingesetzt werden und der konventionellen Therapie sogar uberlegen sein konnen. Methodik und Ergebnisse Eine nekrotisierende Fasziitis des Oberlids bzw. der anterioren Orbita sowie ein therapierefraktarer Lidabszess wurden mittels biologischen Debridements und im 2. Fall zusatzlich mit einem Vakuumverband (VAC-Verband – VAC: Vacuum assisted Closure) behandelt. Erst mit die…
