Emotional picture processing in children: An ERP study
چکیده انگلیسی

The late positive potential (LPP) reflects increased attention to emotional versus neutral stimuli in adults. To date, very few studies have examined the LPP in children, and whether it can be used to measure patterns of emotional processing that are related to dispositional mood characteristics, such as temperamental fear and anxiety. To examine this question, 39 typically developing 5–7 year olds (M age in months = 75.27, SD = 5.83) passively viewed complex emotional and neutral pictures taken from the International Affective Picture System. Maternal report of temperamental fear and anxiety was obtained and fearful behavior during an emotional challenge was observed. As documented in adults, LPP amplitudes to pleasant and unpleasant stimuli were larger than to neutral stimuli, although some gender differences emerged. Larger LPP amplitude differences between unpleasant and neutral stimuli were associated with greater observed fear. The LPP as a measure of individual differences in emotional processing is discussed.

* We examine emotional processing and the LPP in 5–7 year old children. * Like adults, children show larger LPP amplitudes for emotional stimuli. * LPP amplitudes to unpleasant stimuli are associated with fearful behavior. * LPP holds promise as a biomarker for emotional processing biases in children.
