The physical evidence of a spanking varies by observation timing and child biology.

Evidence

But the biology of bruising is not uniform. A slap that leaves no mark on one child produces a vivid bruise on another, depending on skin pigmentation, subcutaneous fat distribution, capillary fragility, and the timing of observation relative to the blow. A bruise that is invisible twelve hours after impact may bloom into purple and yellow by forty-eight hours. An investigator who arrives the same day sees no mark. An investigator who arrives two days later sees evidence of what appears to be considerable force. The same act, the same child, the same parent — different physical evidence depending on when someone looks. — , The Rod and the Child, 6638
