To get an indication of the level of relaxation during the course of an experiment.īesides the three metrics described thus far, the Data Export function of Pro Lab offers access to raw or filtered GSR data as well as information about the onset and peak time of all the SCRs in the data.

To get an indication of the frustration level and task difficulty (e.g.

To evaluate stress level changes over different tasks that study aspects of human behavior (e.g.

Examples of where the GSR average metric is useful to get insights about general emotional arousal levels are: The researcher can use the GSR average metric to determine if a participant is getting stressed, frustrated or relaxed during the course of the test session.

When environmental conditions are kept constant, the slow fluctuations in the GSR signal (tens of seconds to minutes) reflect changes in the emotional arousal level of a participant. Pro Lab also provides a metric related to the general emotional arousal state of a participant: GSR average. SCR count can help identify these moments by comparing the number of SCRs in different moments during the experiment. To identify what specific moments of a dynamic stimulus, such as a video or shopper journey, caused emotional responses in the participants.The GSR metric ER-SCR amplitude can help answer these types of research questions by comparing the ER-SCR amplitude, magnitude and frequency between conditions. a high anxiety group) had larger ER-SCR than another group of participants (e.g. neutral stimuli), or if a group of participants (e.g. threatening stimuli) caused larger ER-SCR than another stimulus condition (e.g. To learn if certain stimulus condition (e.g.Examples of where SCR-related metrics are useful to get insights about the emotional reactions are: When an SCR happens between 1 and 5 seconds after an event, the SCR is then classified as an event-related SCR (ER-SCR) and the amplitude of the SCR gives an indication of the intensity of the emotional response towards the event. An SCR is a temporary increase of the GSR signal amplitude that gives information about what specific moments caused an emotional response within the participant. Pro Lab provides two SCR-related metrics: ER-SCR amplitude and SCR count. The type of research question and experimental design will determine which GSR metrics are more appropriate to answer your research question. Pro Lab offers a set of GSR metrics that are frequently used to quantify skin conductance responses (SCRs) and arousal levels during an experiment. A project collaboration and documentation platform.GSR can add valuable insights to your eye tracking experiment about the emotional arousal state of a participant during various situations.Membership connects and supports the people and projects that shape our future and supports the learning initiatives for the next generation of makers.
