Abstract
English vocabulary is the bricks of the language, and it’s important for English learners to handle accurately English words. Words recitation or dictation is the most widely used simple test form in vocabulary quiz. However, some students do less well in tests due to stress or even meltdown for exam. Here, we apply Brain fingerprinting (BF) in English vocabulary test. We studied the Event Related Potential (ERP) components elicited by familiar English words and strange English words, and used the ERP to decipher whether subject recognized the word presented in the screen. We analyzed the distinct ERP features related to different stimuli (familiar and strange words), and further speculated whether subjects recognized the presenting words from P300 by calculation correlations between different stimuli. The results of 8 subjects implied that familiar words recognized by subjects could be detected from P300 with accepted precision and recall. This means that BF provides a novel alternative for vocabulary quiz and opens the way for application in education, where concealed vocabulary related information stored in mind was detected by measuring brain signals, such as electroencephalography (EEG).
