• A) The halo effect, which leads Jordan to be too lenient when she rates children's aggressive behaviours.
• B) Jordan does not know the children well enough to make inferences about their behaviours.
• C) Jordan cannot reliably explain any patterns of behaviour she might observe.
• D) The setting where Jordan makes her observations is contrived and relatively artificial.
