Visual Strategies in Analogical Reasoning Development: A New Method for Classifying Scanpaths
2013
International audience; Development of analogical reasoning is often explained by general maturation of executive functions. A consequence of the involvement of executive functions would be that children and adults differ in the visual strategies they apply when solving analogical problems. Since visual strategies can be studied by means of eye-tracking, we compared the visual scanpaths of children and adults in three different analogical reasoning tasks. This comparison was done by means of a novel technique that combined a recently developed algorithm for computing a “distance” between any pair of scanpaths (Jarodzka, Holmqvist, & Nyström, 2010), multidimensional scaling (MDS), and a neur…

Le traitement des expressions faciales au cours de la première année : développement et rôle de l'olfaction
2015
The first year of life is critical for the development of the abilities to process facial expressions. Olfaction and expressions are both strongly linked to each other, and it is well known that infants are able to multisensorially integrate their environment as early as birth. However, most of the studies interested in multisensory processing of facial expressions are restricted to the investigation of audio-visual interactions.In this thesis, we firstly aimed to resolve different issues concerning the ontogenesis of infants’ ability to process facial expressions. Our results allowed to specify the development of visual exploratory strategies of facial emotions along the first year of life…
Changes in students’ understanding of and visual attention on digitally represented graphs across two domains in higher education : a postreplication…
2020
Domain-specific understanding of digitally represented graphs is necessary for successful learning within and across domains in higher education. Two recent studies conducted a cross-sectional analysis of graph understanding in different contexts (physics and finance), task concepts, and question types among students of physics, psychology, and economics. However, neither changes in graph processing nor changes in test scores over the course of one semester have been sufficiently researched so far. This eye-tracking replication study with a pretest–posttest design examines and contrasts changes in physics and economics students’ understanding of linear physics and finance graphs. It analyze…
Opiskelijan huomion kiinnittyminen simulaation aikana fysiikan oppitunnilla : silmänliiketutkimus autenttisessa ympäristössä
2017
Tässä pro gradu -tutkielmassa tutkittiin opiskelijan huomion kohdetta lukion fysiikan tunnilla. Tutkimuksessa selvitettiin, vastaako opiskelijan visuaalinen huomio opettajan antamia vihjeitä, kun opettaja opettaa luokassa yhteisesti simulaation avulla. Aineiston kerääminen toteutettiin Tobii Pro Glasses 2 -katseenseurantalaseilla ja SRI-haastattelun avulla ja datan analysointiin käytettiin Microsoft Excel -ohjelmistoa. Luotettavuuden arviointiin käytettiin vertauskoodausta. Tutkimustuloksena oli, että opiskelija seuraa opettajan antamia vihjeitä suurimman osan simulaatio-opetuksen ajasta. Opiskelija katsoi 60 % ajasta sinne, minne opettaja haluaa opiskelijoiden katsovan ja 41 % ajasta opete…
Wider Letter-Spacing Facilitates Word Processing but Impairs Reading Rates of Fast Readers
2020
Previous reports of improved oral reading performance for dyslexic children but not for regular readers when between-letter spacing was enlarged led to the proposal of a dyslexia-specific deficit in visual crowding. However, it is in this context also critical to understand how letter spacing affects visual word recognition and reading in unimpaired readers. Adopting an individual differences approach, the present study, accordingly, examined whether wider letter spacing improves reading performance also for non-impaired adults during silent reading and whether there is an association between letter spacing and crowding sensitivity. We report eye movement data of 24 German students who sile…
Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic
2022
This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.
Professional vision in the classroom: Teachers’ knowledge-based reasoning explaining their visual focus of attention to students
2023
This study investigated Grade 2 teachers' (N = 50) professional vision through eye-tracking methodology and retrospective think-aloud interviews. The study examined the extent to which teachers' knowledge-based reasoning explains their visual focus of attention to whole class and individual students. We found that teachers' descriptions of students' social relations and emotions associated positively with teachers' visual focus of attention to the whole class. Teachers' descriptions of teacher-related information/elaboration and pedagogy linked negatively with teachers' visual focus of attention to individual students. The findings suggest that teachers' visual focus of attention to student…
Experiences from the Use of an Eye-Tracking System in the Wild
2010
Eye-tracking systems have been widely used as a data collection method in the human–computer interaction research field. Eyetracking has typically been applied in stationary environments to evaluate the usability of desktop applications. In the mobile context, user studies with eye-tracking are far more infrequent. In this paper, we report our findings from user tests performed with an eye-tracking system in a forest environment. We present some of the most relevant issues that should be considered when planning a mobile study in the wild using eye-tracking as a data collection method. One of the most challenging finding was the difficulty in identifying where the user actually looked in th…
Eye-tracking the Effects of Representation on Students' Problem Solving Approaches
2017
This study used an eye-tracking method to explore students’ approaches to solving the same task in different representations and the differences between students who answered correctly and those who answered incorrectly when solving the problems. Thirty-one upper secondary students took part in the study. According to the results of this study, the representation has a slight effect on students’ problem solving processes. Students with the incorrect answers paid more attention to the parts of the tasks with information irrelevant to determining the solution to the task. peerReviewed
