QEEG

Retention and learning are neurolinguistic and psycholinguistic processes. The brain electrical response to the cognitive processes that happen in the cortices is inescapable. During neuronal activities, created waves can be recorded and displayed by quantitative electroencephalogram (QEEG) in a non-invasive form. Beta waves are created by thinking, learning, computations, reasoning, attention, and problem-solving activities. This study's primary goal is to objectively investigate the variables impacts of multisensory and non-multisensory methods of instruction on vocabulary retention concerning beta and beta1 waves frequency changes. To meet the purpose, some pre-school novice male and female foreign language learners (age: 5-6 years) participated in this study voluntarily and were assigned into two experimental groups: The Multisensory (three girls and four boys) and Non-multisensory (one girl and six boys) teaching groups. The analyses of the collected data on pre- and post-brain QEEG records of beta and beta1/SMR waves' variations indicated no significant difference between the two groups in the brain oscillatory changes. However, the case study analyses specified the supremacy of beta1 frequency ranges in the Multisensory post-records. The comparative findings of pre- and post-Expressive One Word-Picture-Matching Test (EWPMT) showed that the Multisensory group outperformed the Non-multisensory one; besides, a significant positive relationship was found between beta wave frequency changes on Fp1 and mean score of EWPM post-test in the Multisensory group. The study concluded that the multisensory approach could be a promising method to improve retention at the pre-school level.   

Quantitative electroencephalogram (QEEG) quantitatively records brain wave oscillation changes in any brain activity. Beta waves are produced during brain consciousness when an external stimulus induces computation, reasoning, attention, and logical thinking. Accordingly, the present study tried to measure beta wave changes during writing to analyze the changes of beta oscillatory changes while performing a writing task at the intermediate level. The study followed a quantitative method with the quasi-experimental design. To meet the purpose, thirty foreign language learners (15 males and 15 females) participated in this study voluntarily. They were doing writing tasks while their brain waves were recorded in the F3, F4, and Fz brain regions by applying the QEEG technique. The results reported positive significant differences on beta oscillatory activities in these brain areas, indicating the effectiveness of writing task activities in enhancing attention. The study has implications for language teachers to manipulate creative writing tasks as compositions to enhance attention as a prerequisite of learning and, as a result, beta waves and for the TEFL scholars to apply interdisciplinary approaches to uncover the effects of different tasks on brain oscillatory activities.
