Introduction to Project Analysis

In FaceReader you can:

• Annotate Stimuli and events, to compare different parts of the analysis.
• Automatically present Stimuli to the test participant and synchronize them with FaceReader data (for this purpose use the The Stimulus Presentation Tool). Alternatively, manually present Stimuli to test participants and keep track which analysis parts correspond with the moments the Stimuli were shown.

In the Project Analysis section you can:

• Create and compare groups of participants.
• Calculate mean intensities of facial expressions (and other parameters) of single participants, for participant groups, or when Stimuli were shown. If you have the Action Unit Module you can also calculate statistics for Action Units and Custom Expressions. If you have the Vital Signs Module you can calculate statistics for heart rate, heart rate variability, and breathing rate. If you have the Voice Analysis Module you can calculate statistics for expressions in the voice, loudness and speech rate.
• Calculate relative statistics using baseline correction. For example, calculate the expression intensities of test participants when they watched a certain commercial relative to the expression intensities when they were watching a neutral Stimulus. You can mark the time during which the test participants watched the commercial with a Stimulus.

Note

Project Analysis was not designed for image analyses. Therefore, if your project only contains image analyses, you cannot carry out group analyses.
