Abstract
To test the hypothesis that oral admn. of glutamic acid in human subjects causes improvement in psychological tests of intelligence subjects were divided into 3 main groups; (1) adult patients in a mental-defectives institution, (2) child patients in the same place and (3) boys of normal intelligence. The results of cognitive tests were negative except for equivocal positive evidence in 1 group of normal boys. There was no evidence of improved scores on personality tests.Keywords
