Question

Quizplus · Accepted Answer

The researcher has used a behavioural measure by observing and recording the amount of each type of food the dog consumes. The dog's food preference is inferred from its behaviour of choosing which food to eat. Self-report measures involve obtaining information directly from individuals about their thoughts, feelings, or behaviours, which does not apply here. Physiological measures assess bodily processes such as heart rate or brain activity, which are not relevant to the task at hand. Reactive measures are those that might affect the behaviour being observed, but the researcher has not manipulated any variables that could bias the dog's choice of food.
