EXAMINATION OF THE EFFECTS OF DIFFERENT PRESENTATION TYPES ON THE ATTENTION AND MEDITATION LEVELS OF INDIVIDUALS THROUGH BRAIN WAVES

Abstract

In this study, it was aimed to investigate the relationship between different types of presentations with attention and meditation levels of teacher candidates with brain waves. The study is a quantitative research. The study was based on a semi-experimental single subject research design. An adapted alternating treatments design was used in the study. The sample was formed by convenience sampling model. Convenience sampling model is aimed to select the sample from easily accessible and feasible units because of the limitations in terms of time, money and labor. For this reason, students and academicians from different departments studying at Ondokuz Mayıs University in 2016-2017 education period were taken into consideration taking both time and accessibility into consideration. At the end of the study, the MANOVA Test was performed, normality tests and the extreme values, the calculation of the multi-variance Mahalanobis distance values were checked and the data were found to be normal distribution in both ways. The Box test showed that there was no significant difference between the covariance matrices and the Levene test showed that error variances for the dependent variable scores would be considered equal. As a result, it was observed that different presentation types prepared for different sensory organs had significant differences according to the meditation and attention levels among the groups in some respects. When the data were analyzed in detail, it was found that there was a significant difference between the groups in terms of attention (p = .00) and level of meditation (p = 0,000) but no significant difference in terms of blinking (p = 0.371). In the second part of the study, it was seen that writing a text did not make a significant difference in the level of attention and meditation. However, it has been observed that the sudden drops in attention level and the range of these sudden decreases are significantly different in terms of their range values. Especially, it can be said that the attention interval band has a lot of variation in the attention measurements during short time measurements (1- 2 minutes).
