“…Subjects were exposed to binaural auditory beats with different frequencies combined with flickering lights of 4 different colors (RGBY), and their effect on upper and lower alpha bands has been analyzed. The study showed that this combination can significantly synchronize alpha 1 and alpha 2 bands [11].…”

Studying the effects of different stimulants on the brain is an ongoing research aiming to discover the activities and reactions of the brain. In this sake, we propose a study to show the impact of external stimuli on the human brain. The implementation includes 50 subjects exposed to four various stimuli while recording EEG. First, a control experiment is done where EEG is recorded in the absence of any stimulation. Then, EEG is recorded while the subjects are watching two consecutive sections from nature and violence videos, listening to sections of classical music and then heavy music. The recorded signals are analysed through EEGLAB. The power spectral densities are computed and an analysed. The results showed a decrease in alpha absolute power was observed in 68.1% subjects when watching the nature movie, and in 72.34% subjects when watching the violence video. An increase in alpha and beta absolute power was detected in 70.45% of subjects when listening to the heavy music. Relative power spectral density showed a significant increase of delta rhythm upon watching the video of natural scenes, and a significant increase of alpha rhythm when listening to classical music. ANOVA test is also used to verify if any effect of the stimuli can be observed on each frequency bands. The results showed that the delta rhythm’s highest values were obtained in reaction to the natural scenes video and that there is a significant relationship between alpha rhythms and the stimulus due to Classical music.

“…A self-assessment test platform capable of handling students' affective and cognitive needs would help students improve their knowledge and acquire a positive attitude towards learning. According to Moridis and Economides (2009a) a system of this kind would be able to: (1) recognise the current affective state of the student; (2) distinguish when and how to intervene in order to influence the student's affective state, based on a holistic educational pedagogy integrating affective models in learning; (3) produce the most optimal affective state for learning. Additionally, the tutoring system's affective handling has to be successfully combined with the student's cognitive handling.…”

“…When responding to the Y2 scale, participants blacken the number on the test form to the right of each item-statement (e.g. I lack self-confidence) that best describes the frequency of their feelings: (1) almost never; (2) sometimes; (3) often; (4) almost always. Scores for both the State and Trait Anxiety scales can vary from a minimum of 20 to a maximum of 80.…”
