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 …
Evaluating similarity measures for gaze patterns in the context of representational competence in physics education
2018
The competent handling of representations is required for understanding physics' concepts, developing problem-solving skills, and achieving scientific expertise. Using eye-tracking methodology, we present the contributions of this paper as follows: We first investigated the preferences of students with the different levels of knowledge; experts, intermediates, and novices, in representational competence in the domain of physics problem-solving. It reveals that experts more likely prefer to use vector than other representations. Besides, a similar tendency of table representation usage was observed in all groups. Also, diagram representation has been used less than others. Secondly, we evalu…
Visual attention while solving the test of understanding graphs in kinematics: an eye-tracking analysis
2019
This study used eye-tracking to capture students' visual attention while taking a test of understanding graphs in kinematics (TUG-K). A total of N = 115 upper-secondary-level students from Germany and Switzerland took the 26-item multiple-choice instrument after learning about kinematics graphs in the regular classroom. Besides choosing the correct alternative among research-based distractors, the students were required to judge their response confidence for each question. The items were presented sequentially on a computer screen equipped with a remote eye tracker, resulting in a set of approx. 3000 paired responses (accuracy and confidence) and about 40 h of eye-movement data (approx. 500…
Epistemic network analyses of economics students' graph understanding. An eye-tracking study
2020
Learning to solve graph tasks is one of the key prerequisites of acquiring domain-specific knowledge in most study domains. Analyses of graph understanding often use eye-tracking and focus on analyzing how much time students spend gazing at particular areas of a graph&mdash
From monitoring to sharing of attention in dyadic interaction: The affordances of gaze data to better understand social aspects of remote collaborati…
2020
This paper aims to better understand the social aspects of collaborative problem solving (CPS) through studying joint attention behaviour (JAB) in an online game–like environment. To capture these behaviours and exemplify how ‘jointness’ is achieved in CPS in remote dyadic interaction, event-related measures are utilised based on the following multiple interaction data: (1) individuals’ gaze data from CPS task completion and (2) automatically generated log files (i.e. chats and actions) from dyadic interactions. The results give empirical evidence of the detached, individualistic attention experiences (i.e. monitoring and common attention) and of bidirectional relations (i.e. mutual and sha…
Attentional bias towards interpersonal aggression in depression – an eye movement study
2020
Depressed individuals exhibit an attentional bias towards mood-congruent stimuli, yet evidence for biased processing of threat-related information in human interaction remains scarce. Here, we tested whether an attentional bias towards interpersonally aggressive pictures over interpersonally neutral pictures could be observed to a greater extent in depressed participants than in control participants. Eye movements were recorded while the participants freely viewed visually matched interpersonally aggressive and neutral pictures, which were presented in pairs. Across the groups, participants spent more time looking at neutral pictures than at aggressive pictures, probably reflecting avoidanc…
Does reading medium affect processing and integration of textual and pictorial information? A multimedia eye-tracking study
2020
Abstract This study investigated effects of reading medium (print vs. digital) on integrative processing and integrated understanding of an illustrated text on human sexuality, as well as whether reading medium indirectly affected integrated understanding via integrative processing. Participants were 100 undergraduate and graduate students in educational sciences. Integrative processing was indicated by participants’ gaze transitions between complementary textual and pictorial parts of the document during reading, and integrated understanding was indicated by participants’ integration of textual and pictorial information in post-reading written responses. Results showed that participants wh…
The relationship between children‘s reading ability, verbal and fluid intelligence and measurements of eye movements during reading
2014
The aim of this study was to clarify, which of the following two measures: verbal intelligence or measurements of eye movements, is better predictor of reading ability. In addition, the study also investigated the relationships between reading ability, fluid intelligence and measurements of eye movements. Participants of the study (N = 28; mean age = 8.80; SD = .41; 54% boys) were assessed in reading with LMST-I Reading achievement test, verbal and fluid intelligence was measured using two scales – Verbal Comprehension and Perceptual reasoning – from Latvian edition of Wechsler Intelligence Scale for Children Fourth Edition (WISC- IV, Latvian version), as well as eye tracking was made durin…
NIR tracking assists sports medicine in junior basketball training
2011
We recorded eye movements of eight elite junior basketball players. We hypothesized that a more stable gaze is correlated to a better shot rate. Upon preliminary testing we invited male juniors whose eyes could be reliably tracked in a game situation. To these ends, we used a head-mounted video-based eye tracker. The participants had no record of ocular or other health issues. No significant differences were found between shots made with and without the tracker cap, Paired samples t-test yielded p= .130 for the far and p=.900 > .050 for the middle range shots.The players made 40 shots from common far and middle range locations, 5 and 4 meters respectively for aged 14 years As expected, a st…
<title>Eye movements during silent and oral reading with stabilized versus free head movement and different eye-trackers</title>
2008
Eye movement research of reading has been done on a battery of eye-tracking setups during last decades. We compared reading data of the same group of six students, their eyes were tracked by a video-based helmet-mounted system with the data sampling frequency of 50 Hz and a setup with a chin-rest at 240 Hz. We found that not only the number of fixations may decrease after reading practice, but so does also the mean duration of fixations. In spite of the short duration of saccades, their distributions and changes in them are similarly reported in the two experimental conditions. Lack of significant correlation in the HED data testifies to the result variability due to measurement technique. …
