Novel paradigms to measure variability of behavior in early childhood: posture, gaze, and pupil dilation.

Hepach R, Vaish A, Tomasello M - Front Psychol (2015)

Bottom Line: In one set of studies, children view situations while their eye movements are mapped onto a live scene.In another set of studies, we measured children's emotional expression via changes in their upper-body posture by using depth sensor imaging technology.Together, these paradigms can provide new insights into the internal mechanism and outward emotional expression involved in young children's behavior.

ABSTRACT
A central challenge of investigating the underlying mechanisms of and the individual differences in young children's behavior is the measurement of the internal physiological mechanism and the involved expressive emotions. Here, we illustrate two paradigms that assess concurrent indicators of both children's social perception as well as their emotional expression. In one set of studies, children view situations while their eye movements are mapped onto a live scene. In these studies, children's internal arousal is measured via changes in their pupil dilation by using eye tracking technology. In another set of studies, we measured children's emotional expression via changes in their upper-body posture by using depth sensor imaging technology. Together, these paradigms can provide new insights into the internal mechanism and outward emotional expression involved in young children's behavior.

Mentions: The Kinect allows for a relatively accurate and objective tracking of participants’ body points and an assessment of body posture expansion (see Figure 4). The technology has been employed in several contexts studying infant-caregiver interactions (Nagai et al., 2012), children’s behavior while playing cooperative games (Liu and LaFreniere, 2014), to assess and train motor abilities in clinical rehabilitation programs (Chang et al., 2013; de Greef et al., 2013; Luna-Oliva et al., 2013; Anzalone et al., 2014; Chung et al., 2014), and in interaction research (Won et al., 2014). In principal, the system can track multiple participants (Walczak et al., 2013) and it can be used to measure peripheral physiological measures such as respiratory rate (Burba et al., 2012). However, no experimental study has used the technology to capture the change in children’s body posture as an indicator of emotional expression. This was our aim in recent work, which we describe next. Before doing so, we present the results from a study with adults in an attempt to validate the use of the technology in this way.
