Comparison of brain activity when presenting two-dimensional and three-Dimensional images in students with high and low spatial intelligence

Comparison of brain activity in 2D and 3D educational images (15 images) for high school students with low and high level of spatial intelligence is the main goal of this study. Educational image contents were about heart functioning. From the manipulability perspective, this study belongs to the semi-experimental category. Image dimensions and spatial intelligence are experimental and non-experimental variables respectively. The target population in this study is 2017-2018 high school students in Bardaskan. 50 students with high level of spatial intelligence and 50 students of low level were selected (25 men and 25 women in each group) by cluster sampling method. Their brain activities while watching images were recorded by EEG. Recorded data after noise and artefacts removing (neat data) was analyzed by two way- ANOVA. there wasn’t a significant difference in brain activity between students with low and high level of spatial intelligence ( P value>0.05). there wasn’t a significant difference between brain activity in 2D and 3D and for image dimension and spatial intelligence interaction too ( P value>0.05) but spatial activity is dependent to participants sex (male and female) and there is a significant difference in sex and image dimension interaction ( P value<0.05).
