New Article: Capturing temporal dynamics of fear behaviors on a moment‐to‐moment basis

Detail of fear seqeunces from several children

One early indicator of psychopathology risk for small children shows up in patterns of fear behaviors. In our new paper Capturing temporal dynamics of fear behaviors on a moment‐to‐moment basis, published in Infancy, we apply discrete sequence methods to data about children’s responses to a fearful situation.

One of the very cool things about this paper is that we identify a few different clusters of child behavior. We were hoping to find a way to identify a high fear group at risk to show dysregulated fear, which has psychopathology implications. We found them to some extent, but also identified some other groups that are interesting: a group of external regulators, who use a parent to help regulate their emotions; one low reactive group, who just aren’t that scared by things; and a cool group called fearful explorers who show fear, but don’t let it stop them from checking things out. This work provides some new data points to help understand the emergence of emotion regulation across child development.

Dr. Brick, Ms. Dickens, and Mr. Mundie all attended Penn State’s industryXchange 2019 to talk about new developments from the lab. This year’s workshop focused on sensors and their applications, so we mostly showed off applications of wearable and passive measurement devices, and the ways that they could be applied to improve health and well-being, and assist with psychopathology.

Dr. Brick also presented some upcoming work with Dr. Jessica Menold using these same approaches to enhance workplace efficiency, reduce worker stress and burnout, and improve on-the-job learning.

Emotion Over Time

Core affect is a way of thinking about emotional mood state in terms of two measures: valence (from positive to negative) and arousal (from highly active to placid). So if you’re super ticked off about something, that’s negative valence and high arousal, where if you’re just blissfully chill, you’re low arousal and positive valence.   But people aren’t just in one state forever–much more interesting is the way that they change.

Zita Oravecz and I look at the dynamics of core affect change within an individual in a recent paper: Associations Between Slow- and Fast-Timescale Indicators of Emotional Functioning in the journal Social Psychological and Personality Science.  There, we characterize the changes in core affect within a person in terms of a person’s home base in each dimension, the state they drop back to when there’s no real input, how much they fluctuate around that home base, how strongly their system regulates itself back to base, and the correlations between the ways those characteristics show up in valence and arousal.  Importantly, these characteristics turn out to be predictive of other “trait-level” characteristics, like the strategies you use when you have to deal with negative emotion.
