Looking Tasks Online: Utilizing Webcams to Collect Video Data from Home

Area of Science:

• Developmental Psychology
• Human-Computer Interaction
• Web Technology

Background:

• Online experimentation offers a scalable and cost-effective alternative to traditional data acquisition methods in psychology.
• Web technologies have advanced, presenting opportunities for novel data collection techniques.
• Previous research has not fully explored the feasibility of direct video data recording via web platforms for developmental studies.

Purpose of the Study:

• To investigate the technical feasibility of online video data recording using HyperText Markup Language-5 (HTML5) and JavaScript.
• To assess the viability of this method for collecting behavioral data from young children in a home environment.
• To establish a new, accessible tool for online developmental psychology research.

Main Methods:

• Developed and implemented an online video recording application using HTML5/JavaScript.
• Recruited parent-child dyads for a preferential looking task conducted remotely.
• Utilized a three-stage process: online registration with photo submission, image integration into the experimental design, and webcam-based video data acquisition.

Main Results:

• Successfully recorded video data from infants as young as 4 months old.
• Achieved high data quality, with no exclusions due to technical video issues and only 7% excluded for behavioral reasons.
• Demonstrated high interrater reliability (Fleiss' Kappa, κ = 0.97) for coding visual attention.
• Found that children's attention duration was limited, with interest waning after approximately 10 seconds of static image presentation.

Conclusions:

• Online video data recording is technically feasible and viable for developmental psychology research.
• This method provides sufficient data quality for rigorous analysis, even with very young participants.
• The approach offers a practical solution for broad and accessible data collection in psychological studies conducted remotely.
