I teach a third year course at York University that surveys different aspects of cognition, including, for example, perception, attention, memory, decision making, and language. Teaching the course often brings me outside my research area, and I really enjoy covering the different topics and discussing them with students. Last week we covered perception. While preparing for my lecture I found this great YouTube video of a patient with associative agnosia.
Patients with associative agnosia can copy drawings and match objects, but they cannot identify objects through vision – the video demonstrates this very well. Patients with visual agnosias, in general, are impaired in their ability to interpret visual information. Importantly, however, for these patients vision is not a problem, it is really a matter of interpreting visual information. If you know of any other good videos for teaching cognition, please let me know!
