Investigation of the External Stimuli Effect on Emotion with Biostatistics Methods

Perception is the awareness of objects, qualities or events that stimulate sensory organs in the process of interpreting and making sense. Perception is influenced by emotional experiences, attitudes, goals, ambience and nudity. Detection patterns; sight, hearing, touch, taste, smell, space and time perception. In this study, it was aimed to investigate the effect of external stimuli on human sensation using EMOTIV EPOC + device which is an EEG (Electroencephalography) based device. EMOTIV EPOC is a 14 channel wireless EEG device designed for research and advanced brain computer interface (BCI) applications. The device simultaneously measures connection, excitement, attention, interest, relaxation and stress emotions with the Xavier interface program. In the data collection process, Stroop test proving that visual perception as an external stimulus precedes symbolic- semantic perception, and binaural sound directing brain signals were used. Based on the Stroop effect, a 5-stage game with Unity 3D was developed. In the developed game, 15 healthy 15 girls and 15 boys aged between 20 and 25 were collected for a total of 30 subjects for 6 different emotional states. Post-Hoc test was applied to collected data using SPSS program. As a result of the analysis of the data, it was seen that external stimuli had an effect on human perception. Affecting emotional situations has been seen to be the most attention, link building, stress, excitement, attention and relaxation respectively.
