Self-Regulation

Self-Regulation

Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Background:

Childhood obesity is a global health concern.
Obesogenic environments may impact children's eating behaviors and energy regulation.
Altered inhibitory control is hypothesized to contribute to excessive food intake in overweight children.

Purpose of the Study:

To investigate differences in inhibitory control between overweight/obese and normal-weight children.
To explore the relationship between inhibitory control and body weight status in 10-year-olds.

Main Methods:

Inhibitory control was assessed in 93 overweight/obese and 92 normal-weight 10-year-old children.
The Stroop test and Go/No-Go task were employed to measure inhibitory control.
Event-related potentials (ERPs) were recorded during the Go/No-Go task.

Main Results:

Overweight/obese children demonstrated slower reaction times on the Stroop test.
Increased reaction time variability was observed in overweight/obese children during the Go/No-Go task.
A decreased P300 amplitude in event-related potentials was noted in overweight/obese children.

Conclusions:

The findings suggest impaired inhibitory control in otherwise healthy overweight/obese children.
Altered inhibitory control may play a role in the excessive food consumption observed in this population.
These neurocognitive differences could inform strategies for childhood obesity prevention.
