Another group holding a rubber ball in right palm while reading , then on the left palm while you write down as many words that they remember , the other group did the opposite . The control group did not clench their hands at all .

When Propper and his team conducted the assessment, they found that the group with the best score on a memory test that is their right as memorizing clenched palm and left palm while remembering the words . The group was given an average of ten words , than those in the other groups were given an average of only six words .
