In the second experiment, we repeat and extend Yarbus's original experiment by collecting eye movements of 21 observers viewing 15 natural scenes (including Yarbus's scene) under Yarbus's seven questions. Accordingly, in eye tracking analysis, a common objective is to determine if task or observer characteristics can be decoded from eye movements ( [27,65, 66], see also the work of Yarbus et al .

Acronyms are: intensity (I), color (C), orientation (O), entropy (E), variance, t-junctions (T), x-junctions (X), l-junctions (L), and spatial correlation (Scorr). (2012). However, there is of course a large body of work examining top-down attentional control and eye movements using simple stimuli and tasks such as visual search arrays and cueing tasks (e.g., Bundesen, Habekost, & Kyllingsbk, Due to important implications of Greene et al.

Several high-prevalence neurological disorders involve dysfunctions of oculomotor control and attention, including Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), Fetal Alcohol Spectrum Disorder (FASD), Parkinson's disease (PD), and Alzheimer's. Early in the viewing period, fixations were particularly directed to the faces of the individuals in the painting and observers showed a strong preference to look at the eyes more than any other features of the face.

Further, Yarbus's experiments point towards the active nature of the human visual system as opposed to passively or randomly sampling the visual environment. Sullivan B. (2012). Involuntary covert orienting is contingent on attentional control settings. Mennie N. It is demonstrated that viewing task biases the selection of scene regions and aggregate measures of fixation time on those regions but does not influence other measures, such as the duration of individual fixations.

Models of attentional guidance aim to predict which parts of an image will attract fixations based on image features (7-10) and task demands (11, 12).Classic salience models compute image discontinuities of low-level attributes, such as luminance, color, and orientation ().These low-level models are inspired by "early" visual neurons and their output correlates with neural responses in .

In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands. In what ways do eye movements contribute to everyday activities? Bailey B. This study demonstrates that task decoding is not limited to tasks that naturally take longer to perform and yield multi-second eye-movement recordings, and shows that task can be to some extent decoded from the preparatory eye- Movements before the stimulus is displayed.

On his well-known figure showing task differences in eye movements, Yarbus wrote "Eye movements reflect the human thought process; so the observer's thought may be followed to some extent from the records of eye movements" (Yarbus, 1967, p. 190) In other words, Yarbus believed that an observer's task could be predicted from his static . A chin/head rest was used to minimize head movements. In Canonical correlation and classification results, together with a test of moderation versus mediation, suggest that the cognitive state of the observer moderates the relationship between stimulus-driven visual features and eye-movements. Eye movements were recorded via an SR Research Eyelink eye tracker (spatial resolution 0.5) sampling at 1000 Hz. Wilming N. 2. Itti L. Lemmer K. .

Christopher Kanan, Dina NF Bseiso, Nicholas A Ray, Janet H Hsiao, and Garrison W Cottrell. Copyright 2022 ACM, Inc. It is commonly assumed that eye movements are partially modulated top-down as a function of task demand (e.g., [3,5, 65]).Accordingly, in eye tracking analysis, a common objective is to determine .

This model provides a Bayesian, cognitive approach to top-down transitions in attentional set in pre-frontal areas along with vector-based saccade generation from the superior colliculus and demonstrates that the properties from its generated saccadic vectors closely match those of human observers given a particular task and cognitive state.
