A Multimodal Approach to Measuring Emotion
Fundamentally, all behavioral, self-report, autonomic, hormonal, and imaging data are measuring the activity/output of biological systems at different levels of description.
After decades of emotion research, it is clear that no single measure is capable of providing a comprehensive metric of emotion. It is only through the combined integration of multiple measures that one can start to gain a clear picture of affect and its explanatory reach.
Nearly all prominent contemporary theories of emotion have the Autonomic Nervous System (ANS) at its core. We now know the brain structures responsible for controlling the sympathetic and parasympathetic branches of the ANS are the same structures responsible for regulating cognitive, affective, and behavioral responses. This means that emotions can be quantified by measuring physiological processes that are known to correlate with activity in these brain structures.
One notable advantage of measuring ANS function is that you gain insight into psychological states and neural processes while the participant is engaged in tasks without having to distract or disrupt them.
A study that combines video collection for behavioral outcomes and autonomic monitoring for emotionally driven physiological changes can be minimally invasive, allowing for a pure multimodal measure of emotion.

Specific Risk Factor, Attentional Biases for Facial Displays of Emotion
Much of Professor Dr. Brandon Gibb's (Binghamton University, USA) research focuses on risk for the intergenerational transmission of depression.
In this study, they were interested in how one specific risk factor, attentional biases for facial displays of emotion, which is a known risk factor for depression, may develop in infants of mothers with major depressive disorder (MDD). They hypothesize that attentional avoidance of mom's facial expressions, and sad faces more generally, develop because babies experience increased arousal and negative affect when looking at these faces, which is reduced when they shift their attention away, thereby negatively reinforcing the attentional avoidance.
To really test the hypothesis, it was needed to time-lock the ECG signals to shifts in infants' attention.
- Frame-by-frame video coding with INTERACT
- Import of codes to MindWare software
- E. g. to check an infant's average heart rate in the five seconds before and after a shift in attention away from their mother
„The ability to integrate behavioral codes from Mangold INTERACT with physiological signals obtained with MindWare is perfect and exactly what we need for our project.“
