Internal Consistency of Functional Magnetic Resonance Imaging and Electroencephalography Measures of Reward in Late Childhood and Early Adolescence

Abnormal neural response to reward is increasingly thought to function as a biological correlate of emerging psychopathology during adolescence. However, this view assumes that such responses have good psychometric properties, especially internal consistency—an assumption that is rarely tested. Internal consistency (i.e., split-half reliability) was calculated for event-related potential (ERP) and blood oxygen level–dependent (BOLD) responses to...
