“…Overall, Google Ngram has allowed scholars to shed further light on various topics such as gender differences [ 17 , 18 , 19 ], emotions [ 20 , 21 , 22 , 45 ], personality [ 23 , 24 ], cognition [ 25 , 26 , 27 ], hypnosis and psychotherapy [ 46 ], moral values [ 47 ], education [ 48 ], nature [ 49 ], astrology and phrenology [ 50 ], and the development of individualism and collectivism (e.g., [ 6 , 7 , 10 , 51 , 52 ]). In this respect, despite limitations, we believe that Google Ngram is a beneficial tool for research purposes and that the procedures presented in this guideline can reinforce the reliability of derived results.…”
