Long-term determinants of changes in television viewing time in adults : Prospective analyses from the Young Finns Study
2018
Purpose: The long‐term effects of sociodemographic and health characteristics on television viewing (TV) time changes have not been identified in adulthood. We aimed to examine the modifiable and non‐modifiable determinants of changes in TV‐time in young adults over 10 years.Methods: Participants (N = 2929) aged 24‐39 years were recruited between 2001 and 2011 from the Cardiovascular Risk in Young Finns Study. Data were collected using questionnaires and a medical examination. The determinants of changes in TV‐time were estimated using latent growth modeling for men and women separately.Results: For men, inverse associations with initial levels of TV‐time were observed for students becoming…
A dynamic adjustment model of saccade lengths in reading for word-spaced orthographies : evidence from simulations and invisible boundary experiments
2021
Contemporary models of eye movement control in reading assume a discrete target word selection process preceding saccade length computation, while the selection itself is assumed to be driven by word identification processes. However, a potentially more parsimonious, dynamic adjustment view allows both next word length and its content (e.g. orthographic) to modulate saccade length in a continuous manner. Based on a recently proposed center-based saccade length account (a new regression model of forward saccade length is introduced and validated in a simulation study. Further, additional simulations and gaze-contingent invisible boundary experiments were used to study the cognitive mechanism…
Refining distraction potential testing guidelines by considering differences in glancing behavior
2021
Driver distraction is a recognized cause of traffic accidents. Although the well-known guidelines for measuring distraction of secondary in-car tasks were published by the United States National Highway Traffic Safety Administration (NHTSA) in 2013, studies have raised concerns on the accuracy of the method defined in the guidelines, namely criticizing them for basing the diversity of the driver sample on driver age, and for inconsistent between-group results. In fact, it was recently discovered that the NHTSA driving simulator test is susceptible to rather fortuitous results when the participant sample is randomized. This suggests that the results of said test are highly dependent on the s…
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…
Teachers' visual focus of attention in relation to students' basic academic skills and teachers' individual support for students: An eye-tracking stu…
2022
This study investigated how teachers' visual focus of attention is associated with students' basic academic skills and teachers' individual support for students in basic academic skills in authentic classroom settings. Teachers' (N = 46) visual focus of attention in the classroom was measured with mobile eye-tracking, and students' (N = 879) literacy and math skills were tested in Grade 1. The results revealed that teachers' visual focus of attention in terms of fixation counts correlated with students' basic academic skills and teachers' individual support for students in literacy and math. Two case studies showed that teachers' visual focus of attention varied among students with differen…
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…
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…
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
An interactional ‘live eye tracking’ study in autism spectrum disorder : combining qualitative and quantitative approaches in the study of gaze
2017
Recent studies on gaze behaviours in individuals with autism spectrum disorder (ASD) have utilised “live eye tracking.” Such research has focused on generating quantitative eye tracking measurements, which provide limited (if any) qualitative contextual details of the actual interactions in which gaze occurs. This article presents a novel methodological approach that combines live eye tracking with qualitative interaction analysis, multimodally informed conversation analysis. Drawing on eye tracking and wide-angle video recordings, this combination renders visible some of the functions, or what gaze “does,” in interactional situations. The participants include three children with ASD and th…
Early attraction in temporally controlled sight reading of music
2018
A music reader has to “look ahead” from the notes currently being played—this has usually been called the Eye-Hand Span. Given the restrictions on processing time due to tempo and meter, the Early Attraction Hypothesis suggests that sight readers are likely to locally increase the span of looking ahead in the face of complex upcoming symbols (or symbol relationships). We argue that such stimulus-driven effects on looking ahead are best studied using a measure of Eye-Time Span (ETS) which redefines looking ahead as the metrical distance between the position of a fixation in the score and another position that corresponds to the point of metrical time at fixation onset. In two experiments of …
