This is a detailed presentation. I like the content, but here are few things I would suggest.
1. Change the background of the ppt as it is too dark and the font is too contrast. A lighter background would do.
2. Why is it that maximum words are starting with a Capital letter in your ppt? Please make the changes.
3. The alignment is different in different slides. Some slides have around half inch gap from the left most side, but some have just 0.01. Hope I am making sense.
4. Try to reduce the number of slides in your presentation. As it is on PERCEPTION, it will be perceived as a boring presentation by the audience. The first thing which audience look for in a ppt presentation is the number slides. It does not matter how small each slide is, but it will take interest out of your audience.
5. Try some animations and videos in your presentation. Or, may be a game/practical exercise.
Let me know if I am not clear on any point.
Best of luck.
