Study On The Effect Of Music Priming Stimulus On The Rate Of Speech Production

Music and language are unique phenomena in our human society and play an important role in our daily life.More and more researchers have paid attention to the relationship between these two fields and conducted empirical research on the relationship between them.Whether music and language share similar cognitive processing resources is a controversial issue.However,empirical studies on the relationship between music and language in terms of meaning,syntax,pitch,rhythm and speed show that music and language overlap in cognition.Researchers pay great attention to music perception and the timeliness of language processing.In recent years,many behavioral studies and brain mechanism studies abroad have shown that music and language share a common time processing mechanism.However,there are not many domestic studies on this aspect,and there are few empirical studies on the relationship between music and language from the perspective of time.Previous studies have shown that music priming stimulation has a significant impact on the rate of speech production of the subjects.After hearing the familiar fast melody,the rate of speech production was faster,while after hearing the familiar slow melody,the rate of speech production was slower.This shows that the time processing between music and the language is the same.In addition to tempo,rhythm and meter is also an important variable in music time perception.Some studies have shown that music rhythm and meter can induce implicit prosodic anticipation of language(stress processing).Therefore,researchers used the rhythm sequence of different beats(duple and triple)to investigate the speech processing,and the results showed the cross-domain effect of music rhythm on language processing.Therefore,some researchers proposedthat future studies should also investigate whether the rhythm sequence without melody can initiate the rate of speech production to determine the potential time processing mechanism between music and language.In view of these problems,two experiments were conducted in this study to solve the following questions: 1)can the melody tempo of music affect the rate of speech production? 2)does this influence change due to the influence of music melody familiarity? 3)does the rhythm sequence of different tempo and beats have any influence on the rate of speech production?The purpose of experiment 1 was to investigate whether the change of melody speed would affect the change of speech production rate.2(slow,fast)×2(familiar,unfamiliar)within-subject design was adopted,and the dependent variable was the rate of speech generation of the subjects.The music stimulus material consisted of 20 melodies with a consistent degree of arousal after evaluation,among which half were familiar nursery rhymes and half were unfamiliar short melodies newly created.Half of the melody is presented at a fast speed of 120 bpm and half at a slow speed of 60 bpm.Speech-generated material for the simple contains action cartoon pictures.After each presentation of the music stimulus,the subjects were asked to describe what was on the picture.The purpose of experiment 2 is to investigate whether the change of different rhythm and beat can affect the change of speech production rate.Within-subject design of 2(fast,slow)× 2(duple meter,triple meter)was adopted.The music material consists of 20 rhythmic sequences without melody,still presented at 60 bpm and120bpm,with half of the beats being 2/4 and half 3/4.The task of speech production is the same as that in experiment 1.The results showed that in familiar songs,the faster the melody speed was,the faster the speech production rate was.The slower the melody speed,the slower the speech production rate.No such effect was found in unfamiliar melody.In the rhythm and beat sequence,no matter it is in duple or triple time,the faster the melody tempo is,the faster the speech production rate of the subjects will be,and the slower the melody tempo is,the slower the speech production rate of the subjects will be.In addition,no matter the sequence is slow or fast,the rate of speech production after listening to the tri-meter rhythm sequence is faster than that after listening to the du-meter rhythm sequence.This shows that the time perception of music affects the generation time of speech,and the processing mechanism of the Shared time between music and language.Based on the fact that music and language have some cognitive processing overlaps,this study focused on the timeliness of music and language,and investigated the influence of music tempo,rhythm and beat on the rate of speech production.The research provides evidence for the common time processing mechanism between music and language,and deepens our understanding of music and language in cognition.Future studies can investigate whether such music tempo and rhythm and beat affect the continuity of speech generation speed,especially for the groups with language barriers(such as stuttering),and whether they can obtain sustained or acquired speaking rate from music training to promote their language processing.
