Eye tracking systems have the potential of providing efficient, non-intrusive solutions towards the study of human be-haviour. This work shows that eye movements may be markers of visual information processing and hence can provideinsights into a persons cognitive problem-solving ability and reasoning behaviour. We studied the relationship betweenperformance and eye parameters of individuals for a visual reasoning based problem-solving task. Inter-group analysesrevealed fixation duration and peak saccadic velocity as differentiating markers of performance and time. Intra-groupstudies indicated that the eye parameters acting as performance markers were not the same for all performance groups. Aseparate marker of ’Visual to Textual Processing Ratio’ was defined. Correlating eye parameters with performance couldhelp us develop eye metrics to better mark the cognitive information processing of a person through tests even whereperformance parameters (like score) are not defined.
