  • Easily integrate video and physiological data
  • Calculate statistics and assess reliability


  1. User friendly software package

    The Observer XT is an extremely powerful software tool including data integration and analysis and still very user friendly and easy to understand.

  2. Developed to study time relationships

    Synchronization is the key to understanding behavior patterns. Perfect sync is what researchers expect from Noldus.

  3. Detailed scoring of behaviors

    Designing an ethogram is a crucial step in behavioral research. The ethogram is the actual measuring instrument. Choices made at this stage determine what you can do with your data at later stages. The Observer XT enables you to code behaviors in great detail.
