Neural Correlates of Tactile Attention in Infancy<\/strong><\/p>\n\n\n\n If you would like a copy of the poster, please email Kaitlyn at kaitlyn.campbell@temple.edu <\/p>\n\n\n\n As this data collection is ongoing, this preliminary data analysis consists of 36 infants. Our EEG data quality thresholds included reference electrodes’ data being usable, the proportion of usable EEG channels being 70% or above, at least 40% of trials are usable, and the correlation of the pre and post-line noise reduction is at least .90 or above. HAPPE+ER pipeline was used for data cleaning and a temporal PCA was used for ERP component identification.<\/p>\n\n\n\n Our lab was the first to identify the MMN in the tactile modality in both adults and infants. This analysis is the first to look at the specific functional categories of the fingers in infants. <\/p>\n\n\n\n As the sMMN is sometimes seen as a positive peak instead of negative, we adopted the sMMR as a label instead. Also we looked at the Late sMMR which is the same as the LDN. <\/p>\n\n\n\n The component amplitudes were derived from the tPCA analysis and are the amplitude at the peak latency of each component for each participant. <\/p>\n\n\n\n Ignore the Tap: Neural Correlates of Children\u2019s Voluntary Tactile Attention<\/strong><\/p>\n\n\n\n If you would like a copy of the poster, please email Kaitlyn at kaitlyn.campbell@temple.edu<\/p>\n\n\n\n The overall sample was 56 children but there was technical errors for 3 files and 6 files did not meet EEG quality thresholds. Our quality thresholds included reference electrodes’ data being usable, the proportion of usable EEG channels being 70% or above, at least 40% of trials are usable, and the correlation of the pre and post-line noise reduction is at least .90 or above. <\/p>\n\n\n\n HAPPE+ER pipeline was used for data cleaning and a temporal PCA was used for ERP component identification.<\/p>\n\n\n\n We did an individualized approach to ERP scoring where we used the component’s peak latency and averaged the amplitude 20ms around it.<\/p>\n\n\n\n Summary Statistics<\/strong> (n = 40,208 observations in 47 children)<\/p>\n\n\n\n Multilevel Models Predicting the Amplitude of N80 (z) on Trial and Child Characteristics<\/strong><\/p>\n\n\n\n Data Cleaning Steps: <\/p>\n\n\n\n Infant Behavior Questionnaire-Revised Short-Form (Rothbart & Gartstein, 2000)<\/p>\n\n\n\n Routine-Based Question Examples:<\/p>\n\n\n\n How often did your baby:<\/p>\n\n\n\n (2) seem angry when you left her\/him in the crib<\/strong>?
