The Broad Autism Phenotype in the General Population: Evidence Through Eye-Tracking
… diagnosed with ASD tend to show reduced gaze fixation toward the eye region, but much less eye-tracking research has been done related to the BAP (Boraston & Blakemore, 2007). In this study, we sought to assess eye gaze patterns in people with the behaviorally defined BAP, as defined by a …

Experience Dependent Sensorimotor Functioning in Adults with Severe Autism Spectrum Disorder
… (those with sensorimotor experience) had a First Fixation Location on the incongruent model on the first trial but had a longer First Fixation Duration on the congruent model across the trials. Whereas the non-trampolining group (those without sensorimotor experience) did not attend to either …

Effects of One Neurofeedback Session on Relationship between Fear-Of-Pain and Visual Avoidance of Pain
… scores were negatively associated with total fixation duration while looking at pain-related pictures. One-way ANOVAs revealed differences approaching significance for those trained on Left-Hemisphere NF protocols compared to those in Sham training for total fixation duration, moderate effect …

Gaze behaviour and gait smoothness when navigating complex environments
… trials found no significant differences of fixation duration means between trials with and without a dynamic obstacle (t(4)=-0.113,p=0.458,d=-0.050). There were also no significant differences in pupil diameter means between trials with and without a dynamic obstacle (t(4)=1.032,p=0.180, …

An experimental determination of the effects of image quality on eye movements and search for static and dynamic targets
… (4) that the larger the target, the longer the fixation duration. Low to moderate correlations between MTFA and performance measures generally indicated that as MTFA increases performance improves, and that as MTFA increases fixation duration decreases. The search task of the second experiment …

Experimental Evaluation of Merged-View Systems and VR-Based Reconstruction Approaches for Enhanced Mining Vehicle Teleoperation
… the merged view: blink rate decreased by 29 %, fixation duration shortened by 18 %, saccade amplitude increased by 11 %, and gaze-transition entropy rose by 14 %, reflecting broader and more adaptive scanning. The NASA Task Load Index (NASA-TLX), a widely used subjective workload assessment …

The Use of Habituation to Investigate Basic Level and Superordinate Level Categorization in Cerebral Palsied Infants
… to turn and Attention Holding, as measured by fixation duration.

Eye-movement control during scene viewing
… control and how they are coordinated within a fixation during scene viewing. Additionally, the factors determining fixation durations have long been neglected, as scene perception research has mainly been focused on the factors determining fixation locations. The present thesis aimed at …

Face-to-face interactions and the use of gaze in autism spectrum disorders
… stimuli have indicated a reduced number of fixations towards the eyes, in Autism Spectrum Disorder (ASD). This has been thought to contribute to wider social and emotional difficulties. However, it is unclear whether the reported deficits in gaze can be generalised to real-world …

Understanding the effects of sustainable milk packaging on consumer attention by incorporating eye tracking technology
… Pro Labs measure metrics such as Time To First Fixation (TTFF), Average Fixation Duration and Total Fixation Duration (TFD), which were analysed utilising inferential statistic techniques. Mean tests such as the Analysis Of Variance (ANOVA) and t-tests were conducted to test the hypotheses. In …

Examining Eye Movements In Response To Repeated Exposure To Building Stimuli
… Eye movement measures revealed a decrease in fixation count and saccadic amplitude, and an increase in fixation duration, with increased repetitions. Memory measures revealed improved recognition and confidence, with increased repetitions. These repetition effects align with previous studies …

Investigating the relationship between intelligence and executive function through visual scanning strategies
… efficient visual scanning strategies (i.e. fewer fixations and longer durations). Individuals who made fewer fixations and had longer fixation durations scored higher on block design, matrix reasoning, and vocabulary subscales in the WASI-II, and fixation duration significantly predicted …

The "where" and "when" of eye fixations in reading
… preferred viewing location (PVL), and (3) the Fixation-Duration Inverted-Optimal Viewing Position (IOVP) Effect. Based on a corpus-analytical approach (Exp. 1), the influence of variables word length, launch site distance, and word frequency was systematically explored. In addition, five …

The Effects of Transcranial Direct Current Stimulation (tDCS) on Facial Expression Approach/Avoidance in College Students and Faculty with Broad Autism Phenotype
… measures in response to faces and gaze fixation. The study included 21 total participants recruited from the Science, Technology, Engineering, and Math (STEM) courses / professions at a Regional East Texas University. Participants were classified as BAP+ based on their scores on the …

Looking and Listening Patterns in 4- and 8- Month-Old Infants: Correspondence between Measures of Attention
… visual behavior; infants with short visual fixations who perform well in a recognition task following familiarization and infants with long visual fixation with impaired performance. There are two hypotheses for the differences underlying these groups. First, that visual fixation duration is …

Does Infants' Socially-guided Attention Uniquely Predict Language Development?
… central stimuli to distracters, as well as their fixation duration and gaze count on central events and distracters. It was found that infants' latency away from the abstract figure toward the distracter was the only variable that significantly negatively predicted current expressive vocabulary. …

Evaluating Consumer Response to Environmental Labels on Packaging Using Eye-Tracking
… system to determine differences in gaze durations and time to first fixation between the Forest Stewardship Council (FSC) label and an unsubstantiated label. Labels were placed on two different products (toilet paper and paper plates) and four locations (top-right corner, bottom-right …

Emotion word processing: evidence from electrophysiology, eye movements and decision making
… words presented above and below a central fixation cross. The only significant effects appeared when a positive word was presented in the top condition, and a negative word in the bottom condition. Here saccade latencies were longer and there were a fewer number of errors made. Chapter 4 …

Is it top-down or bottom-up? an evaluation of processes involved in salience and decision making utilising eye-tracking consumer neuroscience research
… study operationalised eye-tacking such as Total Fixation Duration (TFD), First Fixation Duration (FFD) and Time to First Fixation (TTFF) with regards to decision-making. Despite the role of the visual attention processes in consumer decision making, eye-tracking and visual attention processes …

Bidirectional Influence of Emotion Processing on Language Development in Infancy: Evidence from Eye-tracking Mothers and Infants
… in first look tendencies or overall fixation duration to either face in the pair. They also fixated on different areas of the face (infants on mouth region, parents on eye region). Finally, parental sensitivity was examined using a free-play interaction task. Parents' sensitivity was …
