While editing and improving a question on the Cognitive Sciences site, I came across the following sentence:
Infants can detect an upside human face right after they are born
This sounded awkward to me and I struggled to improve it. I believe the author's intention was to say:
Infants can detect a human face right after they are born, as long as the face is not rotated
or:
Infants can detect a human face (in proper orientation) right after they are born.
But I really feel like there must be a word for "in proper orientation" in a context such as this. What would be appropriate?
