īates, D., Mächler, M., Bolker, B., & Walker, S. Syntactic unification operations are reflected in oscillatory dynamics during on-line sentence comprehension. Event-related theta power increases in the human EEG during online sentence processing. Frequency-based segregation of syntactic and semantic unification during online sentence level language comprehension. Event-induced theta responses as a window on the dynamics of memory. Biomedical Signal Processing and Control, 42, 242–252. Cumulative effects of theta binaural beats on brain power and functional connectivity. Both theoretical and practical implications are discussed.Īla, T. Together, we demonstrate, for the first time, the positive impact of binaural beats on auditory language comprehension. However, none of the binaural beats yielded better performance for this task indicating that the benefit of beta and gamma binaural beats may be specific to the interpretation of syntactic relations. To determine if the binaural beat effect can be generalized to another type of syntactic analysis, we conducted Experiment 2 in which another 100 participants indicated whether or not there was a grammatical error in spoken sentences. We found that both beta and gamma binaural beats yielded better performance, compared to the baseline, especially for syntactically more complex object-relative sentences.
In Experiment 1, 100 participants indicated the gender of a noun linked to a transitive action verb in spoken sentences containing either a subject or object-relative center-embedded clause.
In both experiments, participants performed a language task after listening to one of four sounds (i.e., between-subject design): theta (7 Hz), beta (18 Hz), and gamma (40 Hz) binaural beats embedded in music, or the music only (baseline). Here, we investigated the effects of binaural beat stimulation on auditory sentence processing that required interpretation of syntactic relations (Experiment 1) or an evaluation of syntactic well formedness (Experiment 2) with a large cohort of healthy young adults ( N = 200). Binaural beats-an auditory illusion produced when two pure tones of slightly different frequencies are dichotically presented-have been shown to modulate various cognitive and psychological states.
