Question 17
Evaluate the classic study by Olds and Milner (1954).
Worked Solution & Example Answer:Evaluate the classic study by Olds and Milner (1954). - AQA - A-Level Psychology - Question 17 - 2019 - Paper 2
Step 1
Aim of the Study
Answer
The aim of Olds and Milner's study was to investigate whether electrical stimulation of specific areas in the brains of rats could have a reinforcing effect on their behavior. The researchers wanted to understand how rewarding stimuli could influence behavioral patterns.
Step 2
Methodology
Answer
The study involved fifteen male hooded rats. Each rat was equipped with a lever that could deliver electrical stimulation directly to its brain. The rats were subjected to periods of stimulation during which they pressed the lever to receive electrical current to their brains.
Step 3
Step 4
Evaluation of Results
Answer
While the results indicate a strong motivational drive, the validity of the findings can be questioned. The rats were given free access to food and water, which might have influenced behavior. Moreover, the study's methodology may not generalize to all species, as animal behavior can vary significantly. Additionally, the reliability of the results could be affected by the subjective interpretation of the observed behaviors.
