Study Notes on ADHD and Self-Control

Understanding ADHD

Concept of Self-Control

  • Self-Control Defined

    • Self-control is the ability to regulate one's behavior, emotions, and cognitions.

    • It entails actions taken to achieve future goals despite present conflicting desires.

  • Example of Self-Control

    • Scenario with a child:

    • A child is motivated to eat dinner to receive dessert as a reward, displaying self-control by completing the meal.

  • Distinction from Compliance

    • Compliance: Behavior influenced by external authority concerns rather than internal motivation.

    • Example: Obeying parents or teachers due to fear of repercussions rather than for personal gain.

  • Differences in Self-Control Development Among Children

    • Variability exists in self-control levels among children, with some naturally exhibiting better control from a young age.

    • Rank Order Consistency: Recognition that individual differences persist despite overall development progress.

Developmental Aspects of Self-Control

  • Age-Related Improvements

    • Adults generally possess better self-control than toddlers, though individual differences persist.

  • Typical Behavior in Young Children

    • Young children are often distractible and demanding, requiring structured play to develop self-control skills.

    • Transition to Formal Schooling: Children encounter difficulties fitting into structured environments such as kindergarten.

  • Two Sides of Self-Control

    • Bottom-Up Processes: Automatic, stimulus-driven self-control.

    • Top-Down Processes: Deliberate self-control requiring mental effort and working memory.

Outcomes Associated with Self-Control Levels

  • Healthy self-control is linked with:

    • Academic achievement, physical health, personal wealth, and fewer criminal offenses.

  • Risks of Regulation Levels

    • Over-Regulation: Excessive self-control leading to an inability to explore or act freely.

    • Under-Regulation: Deficient self-control resulting in impulsive behaviors.

Role of Executive Function in Self-Control

  • Definition of Executive Function

    • Cognitive processes that enable goal-directed behaviors, intentional actions, and regulation of thoughts and emotions.

    • Correlation with self-control; executive function encompasses more than just behavior regulation.

  • Components of Executive Function

    1. Working Memory: Ability to focus, hold, and manipulate information internally.

    2. Inhibition: Capacity to filter distractions and stay on task.

    3. Termination: Stopping initiated responses to avoid inappropriate actions.

    4. Cognitive Flexibility: Ability to adapt strategies as necessary.

  • Development Over Time

    • Executive function skills develop at different rates throughout childhood, influenced by prefrontal cortex maturation.

  • Genetic Component

    • Genetic predispositions exist regarding executive function, impacting intelligence and self-control levels.

ADHD Diagnosis and Subtypes

  • Patterns in Executive Function and ADHD

    • Deficient executive function is common in ADHD but also appears in other disorders (e.g., ODD, internalizing disorders).

    • Low executive function does not directly imply ADHD without significant inattention, hyperactivity, or impulsivity.

  • ADHD Classification

    • DSM coding has evolved:

    • Previously distinct types (ADHD and ADD) have merged into one disorder, now classified primarily as:

      1. Predominantly Inattentive

      2. Predominantly Hyperactive-Impulsive

      3. Combined Presentation

  • Common Misconception

    • ADHD-HI often diminishes with age leading to a focus on ADHD-C characteristics in adulthood.

Symptoms of ADHD

  • Inattention

    • Characteristics include:

    • Easily distracted by extraneous stimuli.

    • Difficulty listening, organizing tasks, following instructions.

    • High occurrence of careless mistakes in schoolwork.

    • Severity of symptoms reflects a need for enhanced focus, especially with less engaging tasks.

  • Hyperactivity

    • Features:

    • High activity levels, fidgeting, and inability to remain seated during lessons.

    • Motor activity levels comparable to typically developing peers during recess but heightened in structured settings.

  • Impulsivity

    • Manifestations include:

    • Difficulty inhibiting behaviors, excessive talking, losing focus quickly.

    • Safety risks due to impulsive actions without forethought.

    • Disinhibition defined as acting impulsively on immediate rewards (e.g., the marshmallow task).

Early Indicators of ADHD

  • Precursors

    • Symptoms often observed before formal diagnosis between ages 6-12.

    • Include deficits in self-regulation, high activity levels, temper outbursts, aggressive behavior, sleep issues, and sensory processing challenges.

  • Stability of Symptoms

    • Compared to typically developing peers, children with ADHD show minimal improvement in self-regulation and emotional control from preschool to school age.

Impact of ADHD on Functioning

  • Academic Difficulties

    • ADHD leads to worse educational outcomes and higher dependency on school services

    • Increased likelihood of suspension and expulsion, with some evidence of working memory improvement correlating to symptom alleviation.

  • Family Dynamics

    • Significant emotional and economic costs related to treatment and behavioral management.

    • Children often exhibit non-compliance and conflicts with parents, compounded by ineffective parental discipline.

    • Increased parental involvement correlates with better outcomes for adolescents with ADHD, though parenting style does not cause ADHD itself.

  • Peer Relationships

    • Children with ADHD struggle with friendship formation and social skills, leading to peer rejection and cyclical skill development issues.

    • Negative peer impressions may lead to low self-esteem or compensatory behaviors such as narcissism.
