Aims: This paper examines the relationship between observational behavior and the observers' result assumptions, using a contained diagram that includes significant non-verbal information, such as gestures. The ability of care workers to assess a patient's mental status on the basis of non-verbal information would be considered an important skill necessary to understanding patient condition.
Methods: One hundred and eleven subjects were asked to take a test exploring two types of psychological status, and their eye movements were monitored during testing. Path analysis was used to examine the relationships among eye movements, individual personalities, and test results.
Results: In stimulus 1, the neuroticism of the personality was determined. In stimulus 2, openness was determined in the range of eye movement. There is a relationship between the total length of eye fixation time and the answer time at the eye fixation point. Although there was no significant influence found in stimulus 1, the openness still tended to influence the eye fixation point.
Conclusions: The eye fixation point increased among those people with high openness scores. It was theorized that they attempted to obtain information from the stimulus being provided.

Background: When performing a picture description task, healthy individuals tend to look only briefly at a target before beginning its description, after which they move promptly onto the next target. This sequence may be disrupted in those with cognitive impairment. Just as cognitively impaired individuals produce greater numbers of disfluencies and pauses, those with mild cognitive impairment (MCI) may delay speech production by extending their gaze behavior towards a target before beginning its description.

Objective: To investigate if eye tracking can support detection of covert voluntary eye movements and to compare these findings with a simultaneously performed clinical assessment according to the Coma Recovery Scale manual regarding visual stimuli.
Design: Observational case series.
Subjects: Twelve outpatients with prolonged disorders of consciousness recruited from the rehabilitation clinic of a regional rehabilitation unit.

Purpose: To evaluate long-term anatomical and functional outcomes in eyes undergoing scleral fixation of aniridic black diaphragm intraocular lens (BDIOL).
Methods: Total 38 eyes that underwent scleral fixation of BDIOL for secondary aniridia following ocular trauma with aphakia with absent posterior capsule or primary congenital aniridia with subluxated lens were retrospectively analyzed. Final visual acuity, early and late complications were examined.

The subjective visual vertical (VV), the visually estimated direction of gravity, is essential for assessing vestibular function and visuospatial cognition. In this study, we aimed to investigate the mechanisms underlying altered VV perception in stroke participants with unilateral spatial neglect (USN), specifically by examining their eye movement patterns during VV judgment tasks. Participants with USN demonstrated limited eye movement scanning along a rotating bar, often fixating on prominent ends, such as the top or bottom.

Human cognition is reflected in gaze behavior, which involves eye movements to fixate or shift focus between areas. In natural interactions, gaze behavior serves two functions: signal transmission and information gathering. While expert gaze as a tool for gathering information has been studied, its underlying cognitive processes remain insufficiently explored.
