BACKGROUND: Disease risk calculators are increasingly web-based, but previous studies have shown that risk information often poses problems for lay users. OBJECTIVE: To examine how lay people understand the result derived from an online cardiometabolic risk calculator. DESIGN: A qualitative study was performed, using the risk calculator in the Dutch National Prevention Program for cardiometabolic diseases. The study consisted of three parts: (i) attention: completion of the risk calculator while an eye tracker registered eye movements; (ii) recall: completion of a recall task; and (iii) interpretation: participation in a semi-structured interview...

Assessing outcomes and the impact from behavioral nutrition interventions has remained challenging because of the lack of methods available beyond traditional nutrition assessment tools and techniques. With the current high global obesity and related chronic disease rates, novel methods to evaluate the impact of behavioral nutrition-based interventions are much needed. The objective of this narrative review is to describe and review the current status of knowledge as it relates to 4 different innovative methods or tools to assess behavioral nutrition interventions...

OBJECTIVE: To investigate the relationship between silent reading performance and visual field defects in patients with glaucoma using an eye tracking system. METHODS: Fifty glaucoma patients (Group G; mean age, 52.2 years, standard deviation: 11.4 years) and 20 normal controls (Group N; mean age, 46.9 years; standard deviation: 17.2 years) were included in the study. All participants in Group G had early to advanced glaucomatous visual field defects but better than 20/20 visual acuity in both eyes...

The present study assessed intra- and cross-lingual neighborhood effects, using both a generalized lexical decision task and an analysis of a large-scale bilingual eye-tracking corpus (Cop, Dirix, Drieghe, & Duyck, 2016). Using new neighborhood density and frequency measures, the general lexical decision task yielded an inhibitory cross-lingual neighborhood density effect on reading times of second language words, replicating van Heuven, Dijkstra, and Grainger (1998). Reaction times for native language words were not influenced by neighborhood density or frequency but error rates showed cross-lingual neighborhood effects depending on target word frequency...

Wei Zhang, Hantao Liu
Reliably predicting video quality as perceived by humans remains challenging and is of high practical relevance. A significant research trend is to investigate visual saliency and its implications for video quality assessment. Fundamental problems regarding how to acquire reliable eye-tracking data for the purpose of video quality research and how saliency should be incorporated in objective video quality metrics (VQMs) are largely unsolved. In this paper, we propose a refined methodology for reliably collecting eye-tracking data, which essentially eliminates bias induced by each subject having to view multiple variations of the same scene in a conventional experiment...

A growing body of research suggests that individuals with dyslexia struggle to use graphs efficiently. Given the persistence of orthographic processing deficits in dyslexia, this study tested whether graph interpretation deficits in dyslexia are directly related to difficulties processing the orthographic components of graphs (i.e. axes and legend labels). Participants were 80 college students with and without dyslexia. Response times and eye movements were recorded as students answered comprehension questions about simple data displayed in bar graphs...

According to recent theories, social cognition is based on two different types of information-processing; an implicit or action-based one and an explicit or verbal one. The present study examined whether implicit and explicit social-cognitive information processing interact with each other by investigating young children's and adults' use of verbal (i.e., explicit) information to predict others' actions. Employing eye-tracking to measure anticipatory eye-movements as a measure of implicit processing, Experiment 1 presented 1...

When imitating novel actions, typically developing preschoolers often copy components of the demonstration that are unrelated to the modeled action's goal, a phenomenon known as 'overimitation'. According to the social motivation account, overimitation fulfills social affiliation motives (i.e., the imitator's drive to experience social connectedness with the demonstrator and the social context). Conversely, according to the social-cognitive account, overimitation reflects overattribution of causal relevance (i...

Digital whole slide imaging is an increasingly common medium in pathology, with application to education, telemedicine, and rendering second opinions. It has also made it possible to use eye tracking devices to explore the dynamic visual inspection and interpretation of histopathological features of tissue while pathologists review cases. Using whole slide images, the present study examined how a pathologist's diagnosis is influenced by fixed case-level factors, their prior clinical experience, and their patterns of visual inspection...

Emotional arousal impairs top-down attentional control while strengthening bottom-up attentional biases. In this study, we examined whether top-down impairments due to arousal can be modulated by increasing the perceptual salience of the target stimulus. To examine this question, we briefly displayed positive and negative arousing images prior to the encoding of 2 emotionally neutral items, 1 of which was to be remembered and 1 of which was perceptually salient (the to-be-remembered and the salient items were either the same item or different items)...

PURPOSE: The objective of this study is to assess the complexity of human visual search activity during mammographic screening using fractal analysis and to investigate its relationship with case and reader characteristics. METHODS: The study was performed for the task of mammographic screening with simultaneous viewing of four coordinated breast views as typically done in clinical practice. Eye-tracking data and diagnostic decisions collected for 100 mammographic cases (25 normal, 25 benign, 50 malignant) and 10 readers (three board certified radiologists and seven radiology residents), formed the corpus data for this study...

Traditional cognitive assessment in neurological conditions involving physical disability is often prevented by the presence of verbal-motor impairment; to date, an extensive motor-verbal-free neuropsychological battery is not available for such purposes. We adapted a set of neuropsychological tests, assessing language, attentional abilities, executive functions and social cognition, for eye-tracking (ET) control, and explored its feasibility in a sample of healthy participants. Thirty healthy subjects performed a neuropsychological assessment, using an ET-based neuropsychological battery, together with standard "paper and pencil" cognitive measures for frontal (Frontal Assessment Battery-FAB) and working memory abilities (Digit Sequencing Task) and for global cognitive efficiency (Montreal Cognitive Assessment-MoCA)...

Previous research has mainly considered the impact of tone-language experience on ability to discriminate linguistic pitch, but proficient bilingual listening requires differential processing of sound variation in each language context. Here, we ask whether Mandarin-English bilinguals, for whom pitch indicates word distinctions in one language but not the other, can process pitch differently in a Mandarin context vs. an English context. Across three eye-tracked word-learning experiments, results indicated that tone-intonation bilinguals process tone in accordance with the language context...

We assessed quality of life (QoL) and psychological wellbeing in patients with ALS-induced locked-in-state and their next of kin in a fully unbiased manner using eye-tracking computer systems (ETCS). Eleven of 30 screened patients and nine next of kin completed study procedures. Patients reported good QoL which appeared to be at the cost of the QoL of their next of kin. Next of kin rated their own or patients' QoL similarly, but they identified different areas as important as compared with patients. Our results are of importance for the discussion of end-of-life-decisions and the evaluation of the patient's presumed wishes as well as for psychosocial interventions...

In a concurrent eye-tracking and EEG study, we investigated the impact of salience on the monitoring and control of eye movement behavior and the role of visual working memory (VWM) capacity in mediating this effect. Participants made eye movements to a unique line-segment target embedded in a search display also containing a unique distractor. Target and distractor salience was manipulated by varying degree of orientation offset from a homogenous background. VWM capacity was measured using a change-detection task...

Threat sensitivity is a prominent predictor of interpersonal dysfunctions in borderline personality disorder (BPD), leading to intense, aversive feelings of threat and eventually dysfunctional behaviors, such as aggression. In the present study, BPD patients and healthy volunteers classified angry, fearful, neutral, and happy faces presented for 150 ms or 5,000 ms to investigate initial saccades and facial scanning. Patients more often wrongly identified anger, responded slower to all faces, and made faster saccades towards the eyes of briefly presented neutral faces and slower saccades away from fearful eyes compared with healthy volunteers...

Research has demonstrated a link between perspective taking and working memory. Here we used eye tracking to examine the time course with which working memory load (WML) influences perspective-taking ability in a referential communication task and how motivation to take another's perspective modulates these effects. In Experiment 1, where there was no reward or time pressure, listeners only showed evidence of incorporating perspective knowledge during integration of the target object but did not anticipate reference to this common ground object during the pretarget-noun period...

Previous studies have shown that speakers of languages such as German, Spanish, and French reactivate the syntactic gender of the antecedent of a pronoun to license gender agreement. As syntactic gender is assumed to be stored in the lexicon, this has motivated the claim that pronouns in these languages reactivate the lexical entry of their antecedent noun. In contrast, in languages without syntactic gender such as English, lexical retrieval might be unnecessary. We used eye-tracking while reading to examine whether antecedent retrieval involves rapid semantic and phonological reactivation...
