The Assessment of Lingual Tactile Sensation and Perception. This 70s educational film for speech language pathologists is about as technical as its name would suggest. It starts with a very boring lecture by a guy in a 70s brown suit, but forget that. The lecture is followed by footage of a male lab technician giving a series of tests to a female patient on how sensitive her tongue is to tactile stimulation. Dots are drawn on her tongue with a non-toxic ink, she is blindfolded, and her tongue is touched with various items and in various places to see if she can feel them properly, while the boring narrator drones on in the background. Although this is somewhat dull to watch all the way through, the images of the tests are striking and have great creative potential for video artists to use out of context. Ratings: Camp/Humor Value: ***. Weirdness: ****. Historical Interest: ****. Overall Rating: ***.
