       117 . A computer based method for testing the cognitive performance of at least one examinee comprising; 
 providing to at least one examinee at least one measurement-session comprising a plurality of response-series comprising a plurality of responses; and    providing a computer-generated instruction that said examinee respond rapidly to a test stimulus so that at least a minimum number of errors is made:    
   
   
       118 . The computer based method for testing the cognitive performance of at least one exaninee, according to  claim 117 , wherein said instruction is provided prior to a response-series.  
   
   
       119 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 117 , further comprising: 
 determining a number of errors made by said examinee in a response-series; and    displaying a computer-generated instruction to increase a response speed of said examinee when said number of errors is less than a minimum number of errors within said response-series.    
   
   
       120 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 117 , wherein said response-series comprises from about 15 to about 30 responses.  
   
   
       121 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 117 , wherein said minimum number of errors is an integer selected from the group consisting of 1,2,3,4, and 5.  
   
   
       122 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 117 , wherein said minimum number of errors is from about 10% to about 20% of said responses.  
   
   
       123 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 117 , further comprising displaying a warning message when a response-series includes less than said minimum number of errors, wherein said warning instructs said examinee to proceed more rapidly during remaining response-series within said measurement-session.  
   
   
       124 . A computer based method for testing the cognitive performance of at least one examinee comprising: 
 reading at least one word input by an examinee;    determining a performance score by said examinee; and    correlating said score with said at least one health-related word.    
   
   
       125 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 ranking said words by a magnitude of change of said performance score after input of said word.    
   
   
       126 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 determining at least one time period after input of said word;    correlating said word and performance in said at least one time period.    
   
   
       127 . The computer based method for testing the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 displaying a list of words input by said examinee; and    displaying for each said word a correlation between said word and a change of said performance score for said examinee.    
   
   
       128 . The computer based method for measuring the cognitive performance of at least one examinee, according to  claim 126 , wherein said correlation comprises a function including a time differential between an input of a word and a performance score.  
   
   
       129 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 125 , further comprising: 
 providing said examinee with a list of words rated by their correlation with positive changes in performance; and    providing said examinee an explanation that words given highest ratings are most likely to represent beneficial foods and other health-related items.    
   
   
       130 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 providing said examinee with means to obtain a health rating for any word entered at the time of measurement.    
   
   
       131 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 providing first and second health ratings for each said word; and    providing said examinee with means to obtain each said first and second healthy ratings.    
   
   
       132 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 124 , further comprising: 
 providing said examinee with means to search for said entered words with the highest and lowest health ratings.    
   
   
       133 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 123 , further comprising: 
 providing said examinee with means to obtain a health rating for any word combination by concatenating words within the combination.    
   
   
       134 . A computer-based method for word analysis comprising: 
 providing a user with means to obtain a ranking of at least one previously-input word; and    ranking said at least one word by a health or performance change subsequent to said input.    
   
   
       135 . The computer-based method for word analysis, according to  claim 134 , wherein said at least one word is selected from the group of words consisting words describing health-factors, performance factors, and cognitive factors.  
   
   
       136 . The computer-based method for measuring the cognitive performance of at least one examinee, according to  claim 134 , further comprising: 
 providing said examinee with means to select a time-period covered by the analysis.
