  1. pmc Test-Retest Reliability and Measurement Invariance of Executive Function Tasks in Young Children With and Without ADHD
    Sarah L Karalunas
    Oregon Health and Science University, Portland, OR, USA
    J Atten Disord . 2016
    ..However, the test-retest reliabilities of many commonly used EF tasks have rarely been examined in young children. Furthermore, measurement invariance between typically developing and psychiatric populations has not been examined...

    Sarah L Karalunas
    ADHD Research Study, Oregon Health Sciences University, 3181 SW Sam Jackson Park Rd, Portland, OR 97239 9979, USA
    J Abnorm Child Psychol 41:837-50. 2013
    ..Both are believed to be important cognitive mechanisms to the disorder. We demonstrate here that drift rate, or the speed at which information accumulates towards a decision, is able to explain both...

    ADHD Research Study UHN80R1, Oregon Health and Science University, 3181 SW Sam Jackson Park Road, Portland, OR 97239 9979, USA
    Neuropsychology 26:684-94. 2012
    ..RTs are a result of several semi-independent processes, including stimulus encoding, rate of information processing, speed-accuracy trade-offs, and motor response, which have not been previously well characterized...

    Sarah L Karalunas
    ADHD Research Study UHN80R1, Oregon Health and Science University, Portland, OR 97239 9979, USA
    J Child Psychol Psychiatry 54:536-44. 2013
    ..Recent theory and research has emphasized specific low-frequency patterns of RT variability. However, whether group differences are specific to low frequencies is not well examined...
