![]() They found the personality traits O and C were associated with increased Theta and Beta activity across the cortex, while A showed a positive correlation in left central and temporal areas. photic driving was used to examine correlates of personality traits and entrainment. The Five Factor Model (FFM) of personality identifies five traits of personality Neuroticism (N), Extraversion (E), Openness to Experience (O), Agreeableness (A) and Contentiousness (C) and has been subject to a large amount of study examining possible electrophysiological relationships. Currently there are few studies that examine the role individual differences may play in affecting entrainment. ![]() Known as the Frequency Follow Response (FFR), it has been suggested that numerous physiological and psychological processes can be altered through external means, effectively entraining the brain to synchronize neural activity with the stimuli (see for a recent review of existing literature). This suggests a short presentation of steady state binaural beats are not sufficient to alter vigilance or entrain cortical frequencies at the two bands examined and that certain personality traits were not more susceptible than others.Įxternally produced modulation of cortical frequencies can be witnessed via electrophysiological recordings using simple stimuli such as light oscillating at a stable frequency or acoustics such as human speech or consistent tones. Furthermore, no significant relationships were detected between the above and the Big Five personality traits. No significant differences were found in vigilance or cortical frequency power during binaural beat stimulation compared to a white noise control period. EEG was recorded from a high-density electrode cap. Thirty-one participants were played binaural beat stimuli designed to elicit a response at either the Theta (7 Hz) or Beta (16 Hz) frequency bands while undertaking a zero-back vigilance task. This study aimed to examine if binaural beat stimulation altered vigilance or cortical frequencies and if personality traits were involved. Some personality traits measured by the NEO Five Factor Model have been found to alter entrainment using pulsing light stimuli, but as yet no studies have examined if this occurs using steady state presentation of binaural beats for a relatively short presentation of two minutes. ![]() Binaural beats are an auditory phenomenon that has been suggested to alter physiological and cognitive processes including vigilance and brainwave entrainment. ![]()
