I’m sure that there is a lot of neuroscience that you could reference to support this argument if you wanted. The relationship between emotions and illusions is a pretty hot topic.
But as for criticism of your presentation, I think that you have too much text for a slide presentation and not enough symbols or other visual tools. IMHO, a slide presentation should be a visual reference as part of a lecture, and when you read too much off of your slides (instead of using your slides to present visual inormation that you can’t vocally), it runs the risk of becoming boring. One thing you could do would be, with the logical arguments, to add pictoral representations of the chain of reasoning: arrows, equivalence signs, etc. Multiple ways of presentating the same information is always good from an educational standpoint.
