81840 Word Association Test...

this is an online word association test. i want a script which will allow a user to pick an incremental number of words (from a larger word list) see attached word.html. then the test starts... each word appears and script should time the increment between the appearence of the word and their choice of an answer - see word2.html. After they are finished the results page shows their answers for each of the three choices (ordered by response time in descending order) and shows a list of the response times to each word in descending order - see attached [login to view URL] the script should also write all the results (name, age, gender, answers to words, and response time to each word in descending order) to a .dat file - but include a function in the script to turn this feature on or off. the important thing is that this be written so there is not loading/delay issues which would mess up the flow of the test... ideally, right after someone clicks an answer the next word should instantly appear.
