Letter series completion problems (LSC-problems) are common tasks to measure peoples’ ability in problem solving. The process of inductive reasoning in solving such problems was investigated in an experiment by the means of eye movement analysis. We developed an eye movement model on the basis of a process model by Simon and Kotovsky (1963). Our model assigns specific eye movements to three dif...

We examined the nature of eye-hand coupling for the fast correction of on-going arm reaching movements in response to an abrupt target jump. We found a significant correlation between the onset times of eye and arm responses. Importantly, the initial component of the reaching correction was affected by a saccade occurrence even though the onset of reaching correction was prior to the saccade on...

Idiopathic rapid eye movement sleep behaviour disorder is an important risk factor in the development of Parkinson's disease. Numerous potential predictive markers of Parkinson's disease may present before motor symptoms emerge, but testing of these markers in rapid eye movement sleep behaviour disorder has been performed only in small studies. There has been no comparison of markers between pa...

Background: Caffeine is a kind of methylxanthine whose consumption can promote the cognitive and executive functions of the human brain. Objectives: In this study, we seek to investigate the effect of drinking coffee on the period of the eye movement fixation component. Materials and Methods: The research was of the quasi-experimental type. 60 subjects were randomly divided into two group...

EEMML (Emotional Eye Movement Markup Language) is a scripting tool that enables authors to describe and generate emotional eye movement in virtual agents. The EEMML is capable of describing and generating both basic eye movement and emotional eye movement, including primary (joy, sadness, anger, fear, disgust and surprise) and intermediate (emotions that can be represented as the mixture of two...

BACKGROUND Impaired cognition is one of the most common core symptoms of depressive disorder. Eye movement testing mainly reflects patients' cognitive functions, such as cognition, memory, attention, recognition, and recall. This type of testing has great potential to improve theories related to cognitive functioning in depressive episodes as well as potential in its clinical application. AIM...

Method for psychological status monitoring with line of sight vector changes (human eye movement) detected with wearing glass is proposed. Succored eye movement should be an indicator of humans’ psychological status. Probability of succored eye movement, therefore, is measured. Through experiments with simple and complicated documents, relation between psychological status measured with eeg sig...
