She is poised to start rooting the ground when she notices one of her group- mates, a large dominant female, approaching. 3: before conditioning, unconditional stimulus (us) stimulus that causes a natural response. i. e. , the sight of food causes the dog to salivate, unconditional response (ur) natural, instinctive response to stimulus. 8: learning cues: chicken learns to wait until green light switches until she pecks her food, match to sample: chicken learns color matches corresponding to a colored sticker. Cannot bypass step, do routing, or do detours. Good": or does it respond as though the cue were.
