English to Romanian Medical Psychology infant development

Bănuiesc că ar fi sinonim cu "alertness". Cum s-ar traduce în limbaj de specialitate?

Acelaşi context ca şi la întrebarea anterioară:
The BSID-II [Bayley Scales of Infant Development-II] includes a mental scale which evaluates sensory/perceptual activities, discriminations, acquisition of object constancy, memory, learning and problem-solving, vocalization, early verbal communication and abstract thinking, habituation, mental mapping, complex language and mathematical concept formation; a motor scale which evaluates degree of body control, coordination of large muscles, fine manipulation skills, dynamic movement, postural imitation and stereognosis; and a behavior rating scale which measures attention and *arousal*, orientation and engagement, emotional regulation and motor quality.

Mulţumesc anticipat.
