What potential bias could have influenced children's responses in Chaney et al's study?

1. Societal norms concerning medical compliance

2. Children's previous experience with similar devices

3. Children were aware of trying a new device

4. Parental expectations during the experiment

The correct answer is: Children were aware of trying a new device

In Chaney et al's study, the potential bias that could have influenced children's responses is related to their awareness of trying a new device. When children know they are involved in an experiment or trialing a new product, this awareness can lead to altered behavior, often referred to as the Hawthorne effect. Children might demonstrate more positive reactions to the device due to the novelty and excitement associated with it, rather than reflecting their genuine feelings or behaviors toward the device over a longer period. This awareness can create a situation where the children's responses are not purely based on their experience of using the device, but rather influenced by the understanding that they are participating in a study. Therefore, their enthusiasm or curiosity about being part of something new might skew the results, leading researchers to potentially overestimate the acceptability or enjoyment of the device.
