Middle Childhood Development
Physical Development
Aspects of Physical Development
Height & Weight:
Girls generally retain more fatty tissue than boys.
Dental Health:
Tooth decay is a prevalent untreated condition.
Access to proper dental care is essential for children's health.
Nutrition:
Recommended daily caloric intake for children aged 9-13 ranges from 1,400 to 2,600 calories, varying with gender and activity level.
Physical Growth Table (Ages 6 to 11)
Age | Girls Height (inches) | Boys Height (inches) | Girls Weight (pounds) | Boys Weight (pounds) |
|---|---|---|---|---|
6 | 46.8 | 46.8 | 52.3 | 52.6 |
7 | 48.9 | 49.7 | 60.2 | 61.0 |
8 | 51.1 | 52.0 | 69.1 | 69.8 |
9 | 53.9 | 53.5 | 76.9 | 78.1 |
10 | 56.3 | 55.8 | 90.6 | 89.8 |
11 | 59.2 | 58.8 | 106.1 | 102.6 |
Sleep
Average sleep required is about 10 hours daily.
Factors affecting sleep:
Exposure to media screens
Physical inactivity
Secondhand smoke
Poor housing and lack of recreational spaces
Persistent snoring may indicate sleep-disordered breathing, affecting behavior and learning.
Brain Development
Improvements in information processing and focus.
Gray matter volume increases pre-puberty and declines post-puberty due to density loss.
Girls typically experience peak gray matter volume 1-2 years earlier than boys, while white matter increases steadily.
Motor Skills & Physical Activity
Motor skills continue evolving with more complex games during recess:
Boys engage in running and rough play.
Girls prefer games that involve verbal skills and counting.
Younger children (6-9 years) benefit from flexible play rules and additional practice opportunities.
Body Image and Obesity
Body image perceptions emerge prominently, particularly in girls, potentially leading to eating disorders.
Factors contributing to obesity include:
Overweight family members
Poor nutrition, particularly fast food consumption
Sedentary lifestyle.
Chronic vs Acute Medical Conditions
Acute Conditions: Short-term issues like infections.
Chronic Conditions: Conditions lasting over 3 months (e.g., asthma, diabetes).
Asthma: Allergy-based, leads to coughing and wheezing, can stem from genetic and environmental factors.
Diabetes: High blood glucose levels; Type 1 involves insulin deficiency, while Type 2 relates to insulin resistance.
Hypertension: High blood pressure that correlates with learning disabilities.
Cognitive Development
Cognitive Advances in Middle Childhood
Spatial Concepts: Understanding maps, navigating environments.
Causality: Ability to make cause-and-effect judgments.
Categorization:
Seriation: Arranging objects in a specific order.
Transitive Inferences: Understanding relationships among different objects.
Class Inclusion: Understanding the relationship between a whole and its parts.
Inductive and Deductive Reasoning
Inductive Reasoning: Drawing broad conclusions from specific observations.
Deductive Reasoning: Applying general principles to specific cases.
Conservation: Grasping that objects remain identical despite changes in appearance.
Information Processing
d
Planning, Attention, and Memory:
Executive function development allows better concentration, selective attention, and error monitoring.
Increased working memory capacity during middle childhood.
Memory improvement strategies:
Rehearsal laws
Organization
Elaboration
Mnemonic devices
Psychometric Approaches & Intelligence
Common Intelligence Tests:
Wechsler Intelligence Scale for Children (WISC-IV)
Otis-Lennon School Ability Test
Kaufman Assessment Battery for Children (K-ABC-II)
Critique of Intelligence Tests:
Some argue IQ tests may undermine understanding of cognitive abilities in certain health conditions.
Multiple Intelligence and Triarchic Theory
Howard Gardner's Theory of Multiple Intelligences: Encompasses linguistic, logical-mathematical, musical, etc.
Robert Sternberg's Triarchic Theory:
Analytic intelligence: Problem-solving and information processing.
Creative intelligence: Using experience to approach new situations.
Practical intelligence: Daily life adaptability and decision-making.
Language & Literacy
Increased verbal precision including the use of similes and metaphors.
Sentence structures become more complex over time.
Different communication styles view variations between genders; boys are often more direct, while girls are more polite.
Psychosocial Development
Development of Self
Formation of a more complex self-concept, integrating various self-aspects.
Comparison between real self and ideal self shapes self-esteem.
Industry vs. Inferiority (Erikson)
Central Conflict: Children strive to gain competencies leading to either confidence or feelings of inferiority.
Key Virtue: Competence enhances a child’s confidence.
Influencing Factors: Teachers and peers significantly impact children's feelings of industry.
Emotional & Social Understanding
Increased awareness of own and others' emotions.
Development of emotional self-regulation promotes empathy and pro-social behaviors.
Child in the Family
Coregulation: Balance of power between parents and children.
Autonomy impacts a child's relationship with parents.
Exposure to family conflict leads to various emotional responses, affecting behavior positively or negatively.
Peer Relationships
Peer interaction fosters self-efficacy and social skills.
Children are influenced by social structures and nominations from peers (positive and negative).
Understanding aggression types:
Instrumental Aggression: Goal-directed.
Hostile Aggression: aimed to harm others.
Mental Health Issues
Various childhood mental health challenges such as anxiety disorders, oppositional defiance, and conduct disorders.
Resilience can be nurtured through supportive relationships and healthy cognitive functioning.
Moral Development Stages (Kohlberg)
Pre-conventional: Decisions based on rewards and punishments.
Conventional: Adhering to societal standards.
Post-conventional: Principles guide moral reasoning and behavior.
Social Conventional Reasoning: Focus on agreed rules to uphold society.
Moral Personality: Characteristics that encompass moral identity, character, and exemplars.
