FaceReader: Project Analysis Module

The Project Analysis Module can be used for advanced analysis and reporting. With this module, you quickly gain insight into the effects of different stimuli. With the new version of FaceReader, you can now use images as a source of a stimulus as well!

Version 7 allows you to compare responses to different video stimuli in one view, offering faster insights into the effects of stimuli.

Stimuli and markers

Add the stimuli of your choice – you can easily add videos, with or without sound, or images, and simply use the marker function to code and select events such as ‘start commercial’ or ‘distraction’.

  • Event Markers - specify Event Markers, such as when the test participant is distracted, eating, talking etc.
  • Stimuli - specify stimuli with fixed duration. The stimulus has a fixed duration you can specify. And, the stimuli can be a video, for example a commercial. In this case, you can specify the start time of the stimulus within the video file.

The start of a Stimulus or the Start/Stop of an Event is triggered by a key (a letter or number of your choice). For an easy reference all markers and stimuli are visualized in the Timeline.

Independent variables

You can also add independent variables such as educational level or previous knowledge level, which allows you to make groups (female with high education level) and compare results between the groups you have created.

Analysis

The Project Analysis Module offers a number of different analysis and reports:

  • Temporal Analysis - this type of analysis is based on a group response toward a single stimulus. The average response of the group can be viewed side-by-side with the stimulus video, the participant videos and line-charts of the absolute and relative average expression, arousal and valence. The results can also be presented as a pie chart. When the stimulus includes audio, this is also audible when reviewing your results.
  • Numerical Analysis - averages and standard deviations of the responses to stimuli and event markers can be viewed in tables, bar charts, and box-plots. All graphs can be saved as a picture for presentation purposes.
