Towards an understanding of neurophysiological self-regulation in early childhood: A heuristic and a new approach

Neighborhood influences on the development of self-regulation among children of color living in historically disinvested neighborhoods: Moderators and mediating mechanisms

We present a conceptual model of the ways in which built and social environments shape the development of self-regulation in early childhood. Importantly, in centering children of color growing up in historically disinvested neighborhoods, we first describe how systemic structures of racism and social stratification have shaped neighborhood built and social environment features. We then present evidence linking these neighborhood features to children's development of self-regulation. Furthermore, we take a multilevel approach to examining three potential pathways linking neighborhood contexts to self-regulation: school environment and resources, home environment and resources, and child health behaviors. Finally, we consider how racial-ethnic-cultural strengths and multilevel interventions have the potential to buffer children's development of self-regulation in disinvested neighborhood contexts. Advancing multilevel approaches to understand the development of self-regulation among children of color living in historically disinvested neighborhoods is an important step in efforts to promote equity in health and education.

Autonomic tone in children and adults: Pupillary, electrodermal and cardiac activity at rest

Considering the suspected involvement of the autonomic nervous system (ANS) in several neurodevelopmental disorders, a description of its tonus in typical populations and of its maturation between childhood and adulthood is necessary. We aimed to arrive at a better understanding of the maturation of the sympathetic (SNS) and parasympathetic (PNS) tonus by comparing children and adults at rest, via recordings of multiple ANS indices. We recorded simultaneously pupil diameter, electrodermal activity (EDA) and cardiac activity (RR interval and HRV: heart rate variability) in 29 children (6-12 years old) and 30 adults (20-42 years old) during a 5-min rest period. Children exhibited lower RR intervals, higher LF peak frequencies, and lower LF/HF (low frequency/high frequency) ratios compared to adults. Children also produced more spontaneous EDA peaks, reflected in a larger EDA AUC (area under the curve), in comparison with adults. Finally, children displayed a larger median pupil diameter and a higher pupillary hippus frequency than adults. Our results converged towards higher SNS and PNS tones in children compared to adults. Childhood would thus be characterized by a high autonomic tone, possibly reflecting a physiological state compatible with developmental acquisitions.

Psychometric Properties of the Sensory Processing and Self-Regulation Checklist: English Version

Background

Sensory processing supports children's development and abilities to participate in activities across contexts. Self-regulation skills may influence how children process various sensory experiences in daily life activities. The Sensory Processing and Self-Regulation Checklist (SPSRC) is a 130-item caregiver-reported checklist, covering children's essential sensory processing and self-regulation performance in daily activities.

Objectives

This study examines the psychometric properties of the SPSRC (English version) in measuring the sensory processing and self-regulation abilities of children.

Methods

A preliminary field testing of the SPSRC-English was conducted in a sample of n = 194 children (164 without disability and 30 with a disability) to evaluate its reliability and validity properties.

Results

The SPSRC-English was shown to have high internal consistency and test-retest reliability; and good discriminant, structural, and criterion validity in the sensory processing and self-regulation abilities of children with and without disability ages 4-12 years.

Conclusion

The current study provides initial evidence on the reliability and validity of SPSRC-English in measuring the sensory processing and self-regulation abilities in children with and without a disability. The SPSRC-English may provide salient information supporting the understanding of sensory processing difficulties among children.
