The Head-Toes-Knees-Shoulders task (HTKS; Ponitz, McClelland, Matthews, & Morrison, 2009) is a commonly used measure of executive functioning (EF) designed for use with young children. Consistent with the larger literature demonstrating significant relations between EF skills and important developmental outcomes, substantial associations between the HTKS task and reading comprehension, vocabulary, letter and word identification, phonological awareness, and mathematics skills have consistently been reported. Scores on the HTKS task are also consistently associated with behavioral outcomes and other performance-and report-based measures of EF skills. Although the HTKS task is a useful measure of EF for young children, the original version of the HTKS task has a number of limitations. Included among these limitations are consistently reported ceiling effects toward the end of kindergarten, potential motivational issues with older children, and the possibility of errors in administration and scoring using live administration of the task. Lonigan (2013) developed a computerized version of the HTKS task as a means of addressing potential problems associated with near-ceiling performance and motivational issues. The goal of this study was to examine the construct and convergent validity of the computerized version of the HTKS task with important developmental outcomes, to determine its utility as a measure of EF for use with young children. It was hypothesized that the computerized version of the HTKS task would provide an equivalent, if not better, measure of EF in young children as the original HTKS task. In the current study, 126 preschool-aged children were administered both versions of the HTKS as well as a battery of performance-based EF tasks and measures of pre-literacy and mathematics skills. Parents and teachers completed report-based measures of externalizing behaviors. Findings from this study indicated that the computerized version of the HTKS task offered a valid measure of EF, equivalent to that of the original HTKS task, for use with preschool-aged children. Furthermore, the computerized version of the HTKS task offered the added benefits of standardized administration, more accurate scoring of self-corrected responses, and the capability of response-latency in addition to accuracy scoring.
