When students give biased responses to researchers: An exploration of traditional paper vs. computerized self-administration

This article investigates the impact of two data collection modes (online surveys and paper-and-pencil surveys) and the perceived attractiveness of the experimenter on two types of response biases: social desirability and demand artifacts. Its results highlight the combined effect of the data collection mode and the perceived attractiveness of the experimenter on social desirability and show that signs sensitivity and signs interpretation (two types of demand artifacts) are stronger in the context of online surveys than in the context of paper-and-pencil surveys.
