There was no effect of binaural beats on either positive or negative affect for positive affect, both conditions declined in their responses at posttest. Researchers predicted that listening to delta and theta binaural beats would improve mood and creativity at posttest, whereas no influences would be observed for the control group. Participants were randomly assigned to listen to 20 minutes of binaural beats masked by rainforest sounds in the experimental group, or rainforest sounds without binaural beats in the control group. Participants also completed the Remotes Associates Test (RAT) to measure convergent creativity by generating a fourth word pertaining to three stimulus words. Participants completed the Positive Affect and Negative Affect Schedule (PANAS) to measure mood by identifying how closely they felt to certain words pertaining to positive affect and negative affect, respectfully. The purpose of this study is to explore the effects of binaural beats with delta and theta frequencies to determine if these changes can improve mood and creativity using a pre- and post-test experimental design. Binaural beat technology is marketed as a self-improvement tool to reduce stress, improve mood, increase cognition, deepen meditation, and alter states of consciousness.
When two tones of similar frequencies are presented in each ear, the brain responds by perceiving a third tone, known as a binaural beat.
