Research Interests

Research areas, questions, and methods

My current work examines three related areas.

Response Latency in Video-Based Surveys

Focus: Response latency and item- and respondent-related characteristics in video-based noncognitive surveys.

Research questions: How do item length, response format, semantic sufficiency, and respondent characteristics relate to response timing?

Methods: Process-data analysis, multilevel models, item-level indicators, and exploratory visualizations.

Semantic Sufficiency Thresholds

Focus: Identifying the earliest point in a spoken survey item at which sufficient meaning is available to support a response.

Research questions: How consistently do human and AI raters identify sufficient meaning? What implications might this have for identifying premature responses?

Methods: Rater agreement, threshold ratings, and timing-based indicators.

Response Processes in Digital Assessments

Focus: Understanding timing and action patterns in computer-administered tasks.

Research questions: What can time to first action, total response time, and post-first-action timing reveal about task interaction?

Methods: Descriptive process analytics and regression modeling.
