First-graders’ allocation of attentional resources in an emotional Stroop task: The role of heart period variability and classroom climate

Children's Attentional Processes in Outdoor and Indoor Environments: The Role of Physiological Self-Regulation

Previous research has documented that exposure to green spaces has the beneficial effects of attention restoration and stress reduction. This study investigated the effects of indoor (classroom) and outdoor (green school garden) environments on attentional processes in interaction with emotion and physiological self-regulation. Children in third and fourth grades (n = 42) completed a school-related emotional Stroop task assessing the effects of outdoor and indoor classroom backgrounds when facing positive and negative stimuli. Children's attentional patterns in a task completed in both environments were also assessed. Heart rate variability was registered at rest as an index of physiological self-regulation. The results revealed that children were less distracted from negative emotional materials when presented with outdoor compared with indoor background stimuli. Greater selective attention and sustained attention were shown in the green than in the classroom environment. Moreover, sustained attention varied in relation to physiological self-regulation but only when performing the task indoor.

Improvement in parasympathetic regulation is associated with engagement in classroom activity in primary school children experiencing poor classroom climate

BACKGROUND

Self-regulation promotes engagement within the classroom. At a physiological level, a good indicator of the ability of the system to self-regulate is cardiac vagal tone (CVT).

AIMS

The present study aims to assess children's change over time (1 year) in their parasympathetic regulation (by way of CVT) in response to a social and cognitive stressor. Moreover, it addresses whether, if present, this change over time in regulation influences students' engagement in classroom activities while also accounting for classroom climate.

SAMPLE

Forty-nine second graders were assessed at two time points: November 2018 (T1) and 1 year later in 2019 (T2).

METHODS

Children's CVT was registered at rest and while performing a stressful task during which they were asked to cognitively perform while being socially evaluated. Children were also interviewed on how much they feel engaged in classroom activities and their perceptions of classroom climate.

RESULTS

A repeated measures analysis of variance including 2 Time Points ×2 Phases of CVT Registration (baseline and during the stressful task) revealed a significant decrease in cardiac vagal activity from baseline to the task at T1, indicating that initially most children were not able to self-regulate and gave way to a stress response when facing the stressful task. The pattern changed at T2 when an active regulation took place signalled by an increase in CVT from baseline to the stressful task. Data analysis also revealed that among children who perceived a poorer classroom climate, the display of greater parasympathetic regulation over time was linked with higher active engagement in classroom activities.

CONCLUSIONS

Growth in physiological regulation in response to a challenging task is associated with better engagement in classroom activities. Interventions and educational practice promoting the development of self-regulation strategies are recommended.

Reading with induced worry: The role of physiological self-regulation and working memory updating in text comprehension

BACKGROUND

An interplay of emotional and cognitive aspects underlies academic performance. We focused on the contribution of such interplay to text comprehension.

AIMS

We investigated the effect of worry on comprehension and the role of two potential moderators of this effect: physiological self-regulation as resting heart rate variability (HRV) and working memory updating.

SAMPLE

Eighty-two seventh graders were involved in a quasi-experimental design.

METHODS

Students read an informational text in one of two reading conditions: to read for themselves to know more (n = 46; low-worry condition) or to gain the highest score in a ranking (n = 36; high-worry condition). Students' resting HRV was recorded while watching a video of a natural scenario. The executive function of working memory updating was also assessed. After reading, students completed a comprehension task.

RESULTS

Findings revealed the moderating role of HRV in the relationship between induced worry and text comprehension. In the high-worry condition, students with higher resting HRV performed better than students who read under the same instructions but had lower HRV. In contrast, in the low-worry condition, students with higher resting HRV showed a lower performance as compared to students with lower HRV. Finally, working memory updating was positively related to text comprehension.

CONCLUSIONS

Our findings indicate that the cognitive component of anxiety, that is, worry, plays a role in performing a fundamental learning activity like text comprehension. The importance of physiological self-regulation emerges clearly. In a condition of high worry, higher ability to regulate emotions and thoughts acts as a protective factor.

Psychophysiological Regulation and Classroom Climate Influence First and Second Graders' Well-Being: The Role of Body Mass Index

This study examines the associations between physical and emotional well-being and classroom climate, cardiac vagal response, and body mass index (BMI) in a sample of 6- to-8-year-olds. Specifically, we expected a direct link between classroom climate, vagal withdrawal, BMI and children's physical and emotional comfort. Furthermore, we explored whether these individual and environmental characteristics influenced well-being in an interactive fashion. Participants were 142 (63 boys, 44%) first and second graders living in the North of Italy who were interviewed on their emotional and physical comfort. Heart rate and a measure of vagal influence on the heart (cardiac vagal tone) were recorded at rest and during an oral academic test. Height and weight were collected. Classroom climate was positively linked with physical well-being, whereas emotional well-being was negatively related with BMI. In addition, an inverted U-shaped effect of cardiac vagal withdrawal (i.e., cardiac vagal tone during stress minus resting vagal tone) on emotional well-being was found. Two regression models highlighted the role played by BMI when interacting with vagal withdrawal in predicting children's physical and emotional well-being. The interplay between BMI and cardiac vagal withdrawal played an important role in primary school children's well-being. From a clinical perspective, preventive training to improve autonomic regulation in concert with interventions promoting healthy eating attitudes might be critical for supporting primary school children's emotional and physical health.

Physiological responses to a school task: The role of student-teacher relationships and students' emotional appraisal

BACKGROUND

To be successful, students must learn to deal with socially and cognitively demanding tasks. Much remains unknown about the effects of previous classroom experiences and of students' emotional appraisal of a task on their physiological adaptive responses to it.

AIMS

To investigate how children's physiological response to a social and cognitive task would be directly and interactively influenced by the perceived student-teacher relationship and by children's emotional appraisal of what reaction they expect to have while completing the task.

METHODS

One hundred and sixteen second and third graders took part in the study. Children completed a cognitive and social stress task. Before the task, they were interviewed on their emotional appraisal of the task and on student-teacher relationships. Children's cardiac activity was registered at rest and during the task to measure physiological activation (heart rate) and self-regulation (heart rate variability).

RESULTS

Heart rate variability during the task was positively correlated with the appraised emotional valence of the task and of being observed while doing it. Regression analyses showed that children's physiological self-regulation during the task was affected by the interaction between student-teacher relationships and appraised emotional valence of being observed. Only among children who had experienced negative student-teacher relationships, an active physiological self-regulation was observed in response to the task when they expected it to be positive compared to when they perceived it as negative.

CONCLUSIONS

Children's emotional appraisal of tasks and the quality of student-teacher relationships are important to promote a functional physiological response of self-regulation that underlies academic functioning and well-being at school.

The longitudinal negative impact of early stressful events on emotional and physical well-being: The buffering role of cardiac vagal development

Early stressful events negatively affect emotional and physical well-being. Cardiac vagal tone (CVT), which is associated with better emotional and physical well-being, usually gradually increase in early childhood. Nonetheless, children's CVT developmental trajectories are greatly variable, such that CVT can increase or decrease across the years. The present study examines the longitudinal effects of early stressful events and the role of 4 years CVT developmental trajectory on children's emotional and physical well-being. Forty-two 4-year-old children were enrolled. Number of stressful events and resting electrocardiogram (ECG) were collected at T1. ECG was registered again after one (T2), two (T3) and three (T4) years. Children's emotional and physical well-being were assessed at T4 through the Child Health and Illness Profile - Child Edition (CHIP-CE). CVT development was calculated as the angular coefficient, reflecting the developmental trajectory of CVT across the four timepoints. Results yielded that higher experienced stressful events predicted poorer emotional and physical well-being after 4 years. The interaction between the number of stressful events and CVT development emerged on physical well-being. Early stressful events negatively affect long-term children's emotional and physical well-being while a positive CVT development seems to mitigate the negative effects of early stressful events on physical well-being.
