Area of Science:

Survey Methodology
Cognitive Psychology
Data Analysis

Background:

Survey respondents ideally provide accurate answers reflecting their knowledge.
However, response behaviors can be influenced by heuristics, reducing data quality.
Identifying these behaviors is crucial for robust survey analysis.

Purpose of the Study:

To develop a model distinguishing various respondent behaviors.
To incorporate eye-tracking data to identify item-respondent level behaviors.
To enhance the informativeness of survey data analysis by accounting for response behaviors.

Main Methods:

Utilized eye-tracking data as covariates.
Employed a Bayesian switching-mixture model.
Identified distinct response behaviors at the item-respondent level.

Main Results:

The model differentiates response behaviors influenced by previous responses (positive/negative).
It also identifies responses reflecting respondents' pre-existing knowledge.
Controlling for these adaptive behaviors leads to more informative survey analysis.

Conclusions:

Accounting for multiple adaptive response behaviors improves survey data analysis.
Eye-tracking data provides valuable insights into respondent behavior.
This approach enhances the validity and reliability of survey findings.
