The effectiveness of a school mindfulness-based intervention on the neural correlates of inhibitory control in children at risk: A randomized control trial

Interest in the applications of mindfulness practice in education is growing in the scientific community. Recent research has shown that mindfulness practice in schools may be beneficial for executive functions (EFs) which are abilities crucial for healthy development. The study of the effects of mindfulness practices on children's neural correlates of EFs, particularly inhibitory control, may provide relevant information about the impact and mechanisms of mindfulness-based interventions (MBIs) in children. The aim of the present study was to investigate the effects of a MBI in elementary school children on the neural correlates of inhibitory control via a randomized controlled trial. Children from two 4th grade classrooms and two 5th grade classrooms located in a school identified as having low socioeconomic status in Santiago de Chile were randomly assigned to either receive a MBI or serve as active controls and receive a social skills program. Both before and after the interventions, electroencephalographic activity was recorded during a modified version of the Go/Nogo task in a subsample of children in each group. Additionally, teachers completed questionnaires of students’ EFs and students completed self-report measures. Results revealed increases in EFs assessed by questionnaires together with improved P3 amplitude associated with successful response inhibition in children who received the MBI compared to active controls. These results contribute to the understanding of the ways in which mindfulness practices can promote the development of inhibitory control together with EF improvement, factors identified as critical for children's social and emotional development and positive mental health.

Research Highlights

• This study investigated the effects of a mindfulness-based intervention in children from a low socioeconomic status school on neural correlates of EFs.
• Children performed a Go/Nogo task while electroencephalographic activity was recorded and completed questionnaires before and after a MBI or an active control program.
• Improvements in EFs assessed by questionnaires together with an increased Nogo-P3 activity associated with successful inhibition in children who received the MBI were found.
• The results could contribute to understand how mindfulness practice can promote the development of inhibitory control in children from vulnerable populations.

     

Searching for nothing: placing zero on the temporal continuum

Animal Cognition - Generalization allows responses acquired in one situation to be transferred to similar situations. For temporal stimuli, a discontinuity has been found between zero and non-zero...     

Interest in smoking cessation among emergency department patients.

The authors interviewed adult patients presenting to 4 Boston emergency departments (EDs) about their smoking, quit attempts, and interest in an outpatient referral. Of the 539 patients enrolled, 26% were current smokers. Of the current smokers, 72% had tried to quit in the past year, and 34% wanted an outpatient referral. Current smokers were younger than nonsmokers and were less likely to have a high school education, primary care provider, and private insurance. The findings of this study reinforce the potential benefit of routine screening for smoking and interest in quitting in the ED. Because many underinsured Americans use the ED as a source of regular health care, the public health implications of increasing screening, counseling, and referral for smokers are substantial.     

Four Weeks of Neuromuscular Training Improve Static and Dynamic Postural Control in Overweight and Obese Children: A Randomized Controlled Trial

Abstract

Thirty-two children with overweight or obesity were randomly divided into a neuromuscular training group (NTG) (n = 16) and a control group (CG) (n = 16). All individuals participated in the measurement of static postural control under two conditions: the double-leg stance with eyes open (EO) and eyes closed (EC). The center of pressure variables was obtained. mSEBT was used for dynamic postural control. Neuromuscular training was performed twice per week and lasted 4 weeks. The results of this study indicate that 4 weeks of neuromuscular training improve static and dynamic postural control in children with excess body weight.
