How does participant reactivity most frequently manifest in psychological research?

Participant reactivity is a phenomenon that exclusively involves participants intentionally trying to disrupt or sabotage the research data.

A psychologist is designing a study on social behavior and wants to account for the impact of measurement on the subjects. Arrange the following research scenarios in order from the highest likely participant reactivity (1) to the lowest likely participant reactivity (3).

A researcher is evaluating different ways that measurement can influence human behavior. Match each research scenario with the specific manifestation of participant reactivity it demonstrates.

An external reviewer critiques a study on social interactions and concludes that the data is 'contaminated' because the participants' awareness of the recording devices led them to behave more politely than they would in a natural setting. By making this judgment, the reviewer is identifying ____ as the primary threat that has compromised the study's validity.
