“…Although numerous other studies of parent-child interactions also used samples of behavior that range from 2 to 5 min (e.g., Meek, Robinson, & Jahromi, 2012;Siller, Hutman, & Sigman, 2013) or 6 to 10 min (e.g., Patterson, Elder, Gulsrud, & Kasari, 2014;Wan et al, 2013), 5 min of observation time is short in comparison with other studies that observed parent-child interactions from 15 to 40 min comprised of playing with toys, making music, book reading, etc. (Adamson et al, 2004;Bottema-Beutel et al, 2014).…”
