Gonzales, Christopher R.; Bowles, Ryan; Geldhof, G. John; Cameron, Claire; Tracy, Alexis; McClelland, Megan M. – Grantee Submission, 2021
Measures of self-regulation may not capture adequate variability in children with low levels of self-regulation. This can limit a measure's ability to accurately demonstrate relations with other variables. The present study addressed this issue with a revised version of the Head-Toes-Knees-Shoulders task (HTKS-R), which includes a new downward…
