A study of brain reaction to spatial stimuli in students with different background knowledge

ABSTRACT

Based on neurology and cognitive science, many studies have been made to understand the human mental model, in order to learn how human cognition works. It is especially relevant when the problem is related to learning processes that involve complex contents and spatial-logical reasoning, related to superior education. This paper focuses on EEG techniques to help understand cognitive pathway in subjects from different backgrounds when they are exposed to an external stimulation of logical and spatial reasoning. It can be used to access aspects of human cognitive processing, through the changes of rhythm of the brain bands frequency, which indicate that some type of processing or neuronal behavior is happening. The EEG signals were captured using an ADC (Analogical Digital System) board with the LabVIEW system - National Instruments. The research was performed using Design of Experiments – DOE and signal processing was done (math and statistical techniques) showing the relationship between cognitive pathway by groups and intergroups.
