Question which may sound silly:  Has there ever been a study done which takes an 'average' of "word associations" and used this information for teaching related vocabulary?  Example:  I'm learning Russian, and I would like to see the product of a native Russian's (or a whole bunch of native Russians) 'word association' - something like "happy", "sad", "mad", "glad", "sunny", "warm", "cold", "old", "bold", "mold", "mildew", "fungus" might be in English...  There might be some words which rhyme, other words which are opposites, other words which are similar in meaning, some words which are the same amount of syllables, etc.  I'm rather pedestrian, as far as language acquisition goes, but I tend to be "right brained", as they say, and am a big fan of the neural network concept of how the brain is mapped, and stores information.  If anybody knows of anything like this, I would be quite interested.  Thoughts?  Information?  -Kenneth
