Respondents' problem-solving behaviors comprise behaviors that represent complicated
cognitive processes that are frequently systematically tied to one another. Biometric data,
such as visual fixation counts (FCs), which are an important eye-tracking indicator, can be
combined with other types of variables that reflect different aspects of problem-solving
behavior to quantify variability in problem-solving behavior. To provide comprehensive
feedback and accurate diagnosis when using such multimodal data, the present study …

Problem-solving behavior consists of activities carried out by respondents, which reflect
complex cognitive processes that are often systematically related to one another. To
measure this variety in problem-solving behavior, biometric data including visual fixation
counts (FCs), an essential eye-tracking indicator, can jointly be modeled with other types of
variables reflecting different facets of problem-solving. To improve the comprehensiveness
and accuracy in using such multimodal data for diagnosis of problem-solving, the present …
