Valence effects on phonological processing in normal Persian speaking children: A study by ERP
Foreign language teaching and learning
پژوهشي
Research
Objective: Emotional content and language processing has mutual relationship. But there is limited evidence in emotional production. Verbal emotion has two aspect including arousal and valence. The aim of the present study is investigation of effect of valence on phonological processing in Persian speaking children by ERP.<br>
Material and methods: One hundred and twenty emotional words in three categories including positive (high valence or pleasant), negative (low valence or unpleasant) and neutral was given to 10 normal Persian speaking children to read aloud. Concurrently, Event Related Potentials were recorded by 64 electrodes. Phonological processing was supposed to be 100-400ms before articulation onset. Behavioral and electrophysiological results were analyzed in this time range.<br>
Results: Positive words have more accuracy and smaller reaction time compare to negative words. These differences were statistically significant. Positive words extracted larger amplitude in frontal, temporal and posterior regions. Neutral word have larger amplitude in central regions. Topography illustrated diffuse activity in emotional words. There were significant differences between negative, positive and neutral words in prefrontal and right posterior regions.<br>
Conclusion: Emotion increases brain activity in some regions. It lead in faster processing. Emotional content decreases amplitude and helps to phonological processing in limited regions.
