Not so much useful as interesting, this article published by the National Academy of Sciences argues that the Whorfian hypothesis is more strongly observed in one's Right Visual Field as opposed to the Left Visual Field when using the experiment with colors and the language associated with it.
Interesting article centered on peoples abilities to interpret languages that we use. Also, how body language and tone of voice triggers senses in the person within the discussion.
One of the first sites that came up on google, but a more thorough, more easily understandable explanation of the hypothesis. It's valuable because it provides citations supporting the hypothesis and other information directly from Sapir and Whorf
