Abstract

This paper aims to investigate the functional connectivity in brain among young children during employment of preferred and non-preferred rule when drawing basic drawing task using Partial Directed Coherence (PDC) and to determine the most significant parameter in differentiating the two groups using handwriting dynamic features and brain activity based on statistical analysis and principle component analysis (PCA). Twelve subjects between 5 and 6 years old were selected randomly. All subjects were asked to gaze and trace four different unlined shapes. The brain signals were recorded using an electroencephalogram (EEG) machine during drawing tasks. Result showed that subjects who employed preferred graphic rule (Control) when performing gazing and tracing tasks were better at visual processing when compared to those that used graphic rule in haphazard fashion. Besides, significant difference was found in frequency domain when subjects used graphic rule in rule governed fashion when compared to relaxing activity. The contrast was found when subject used graphic rule in haphazard fashion. Results from PCA showed most significant parameter (gamma/high gamma) in differentiating between the two groups (employed graphic rule vs. non-graphic) was found in tracing task.
