Purpose: Poor sleep is associated with short-term dysregulation of mood and is a risk factor for major depressive disorder (MDD). This study examines whether objectively measured sleep in late adolescence prospectively predicts major depressive episode (MDE) onset in early adulthood as well as whether daily affect mediates this association.…

Processes of classroom emotional transmission have been identified whereby the emotions expressed by an individual are induced in others, with particular attention paid to how this unfolds among teachers and their students. However, there is still much to be clarified about how teachers' and students' emotions transmit in the classroom, including…

Emotions play an important role in the work of teachers serving students with emotional and behavioral disabilities (EBD), yet little is known about teachers' momentary affective experiences. In this study, we collected 710 surveys regarding momentary affect from 14 teachers of students with EBD. We used descriptive analysis and variance…

Early interaction is a dynamic, emotional process in which infants influence and are influ­enced by caregivers and peers. This chapter reviews new developments in behavior imag­ing--objective quantification of human action--and computational approaches to the study of early emotional interaction and development. Advances in the automated…

At the onset of the coronavirus disease (COVID-19) global pandemic, our interdisciplinary team hypothesized that a mathematical misconception--whole number bias (WNB)--contributed to beliefs that COVID-19 was less fatal than the flu. We created a brief online educational intervention for adults, leveraging evidence-based cognitive science…

We developed generalizable affect detectors using 133,966 instances of 18 affective states collected from 69,174 students who interacted with an online math learning platform called Algebra Nation over the entire school year. To enable scalability and generalizability, we used generic interaction features (e.g., viewing a video, taking a quiz),…

The current laboratory-based study examined individual differences in sadness coherence (i.e., coherence between objectively coded sad facial expressions and heart rate in response to a sad film clip) and associations with dispositional affect (i.e., positive and negative affect, extraversion, neuroticism) and age in a sample of younger and older…

We conducted an exploratory study on affect regulation during game-based learning where 110 college-aged participants (M[subscript age] = 22.14, SD[subscript age] = 1.24; 50.0% female; 70.0% White) played an easy, medium, and difficult level of an educational game (Physics Playground) while self-reporting their strongest affective state and…

Research shows greater mindfulness is associated with less negative affect and more positive affect. Fewer studies have examined the mediating psychological processes linking mindfulness to these outcomes in adolescents. This three-wave, prospective longitudinal study examines rumination--the tendency to engage in repetitive and negative…

The well-studied Baker et al., affect detectors on boredom, frustration, confusion and engagement concentration with ASSISTments dataset were used to predict state tests scores, college enrollment, and even whether a student majored in a STEM field. In this paper, we present three attempts to improve upon current affect detectors. The first…
