Why do animal behaviorists have to account for a habituation period when undertaking an observational study?
They must make sure the study animals do not imprint on them.
They must wait until their presence no longer affects the behaviour of the animals.
The animals need time to associate the observer with data collection.
Before insight learning can be observed, the animals must practise.
The animals must remain cautious of the observer at all times.
