DConditioning effect
Correct answer: (C) Regression effect — A shift in respondents' attitude between two points in data collection is called the regression effect, so that is the answer.
Explanation
★A shift in respondents' attitude between two points in data collection is called the regression effect, so that is the answer.
★The regression effect is a change in responses as measurement is repeated over time.
★So a shift in the response attitude between two measurement points is treated as the regression effect.
★The reactive effect is the change caused by respondents knowing they are being studied.
★The maturation effect is a change due to natural growth or fatigue within the respondents.
★The conditioning effect is a learned change from repeated exposure, so this attitude shift is the regression effect.
