“…In pink noise, there is an equal amount of noise power in each octave. Studies have shown that it has a significant effect on improving sleep quality [6] and memory [7]. Traffic noise is one of the most prevalent noises in our daily lives.…”

Dalbergia pinnata (Lour.) Prain (D. pinnata) is a valuable medicinal plant, and its volatile parts have a pleasant aroma. In recent years, there have been a large number of studies investigating the effect of aroma on human performance. However, the effect of the aroma of D. pinnata on human psychophysiological activity has not been reported. Few reports have been made about the effects of aroma and sound on human electroencephalographic (EEG) activity. This study aimed to investigate the effects of D. pinnata essential oil in EEG activity response to various auditory stimuli. In the EEG study, 30 healthy volunteers (15 men and 15 women) participated. The electroencephalogram changes of participants during the essential oil (EO) of D. pinnata inhalation under white noise, pink noise and traffic noise stimulations were recorded. EEG data from 30 electrodes placed on the scalp were analyzed according to the international 10–20 system. The EO of D. pinnata had various effects on the brain when subjected to different auditory stimuli. In EEG studies, delta waves increased by 20% in noiseless and white noise environments, a change that may aid sleep and relaxation. In the presence of pink noise and traffic noise, alpha and delta wave activity (frontal pole and frontal lobe) increased markedly when inhaling the EO of D. pinnata, a change that may help reduce anxiety. When inhaling the EO of D. pinnata with different auditory stimuli, women are more likely to relax and get sleepy compared to men.

Effects of gamma frequency binaural beats on attention and anxiety

Binaural beats (BB) are an auditory phenomenon produced from a combination of two sine waves with slightly different frequencies presented to each ear. Previous research has implicated the role of BBs through brainwave entrainment in potentially giving rise to benefits ranging from enhanced memory and attention to reduced anxiety and stress. Here, we investigated the effect of gamma (40-Hz) BBs on attention using the attention network test (ANT), a previously unused task that assesses three subtypes of attention: Alerting, Orienting, and Executive Control.Fifty-eight healthy adults performed the ANT remotely under the exposure of 340-Hz BBs and a 380-Hz control tone. All completed a rating scale for levels of anxiety before and after each exposure. Performance on the ANT task (reaction time and error rates) between BB and control groups was evaluated using Wilcoxon signed-rank tests.We found no significant differences in Reaction Time (RT), Error Rate (ER), or the efficacy of the Attention Networks (AN) between the experimental and control conditions (p > 0.05). We found no effect of BB on self-rated measures of anxiety. Our findings do not provide evidence for improvement in attention with gamma BB.

<p style="text-align: justify;">This paper presents a systematical review of facilitation techniques for creativity in general and insight solutions in particular. The facilitation techniques are fairly diverse, therefore we grouped them into nine categories: rest, attention management, impact of emotions, adding new context, physical activity, interactivity, future-thought priming, metacognitive training, and unusual techniques for increasing creativity. Each category is provided by a brief description and a set of studies that demonstrate possibilities and limitations of the techniques as well as an analysis and comparison of the techniques with each other. At the conclusion, we present a model of levels of creative solution facilitation based on four classical psychological levels. According to this model, influence on the solution can be carried out (1) through conscious strategies for managing the solution through metacognition; due to changes occurring in (2) cognitive and (3) emotional-motivational processes; (4) indirectly, due to changes in the external environment. We made a general conclusion about the variety of techniques that influence the creativity process, and most of them combine several possible facilitation mechanisms, making each technique more effective and applicable to various types of creative tasks.</p>
