Study Notes

Development

Development is dependent on opportunity
Development is multidimensional: biological, psychological, and social
Development is multidirectional: growth and decline occur simultaneously in all areas of development
Development is influenced by age-graded influences, historical influences, and interacting forces
Age-graded influences are age norms, like feeding, walking, and attending school
Historical-graded influences are events occurring during a period, like wars, pandemics, or social movements

Developmental Theories

Behaviorism focuses on how behaviors are learned through conditioning
Classical conditioning focuses on associating a neutral stimulus with a natural, unconditioned response
Operant conditioning focuses on using reinforcement to modify behaviors, such as rewards or punishments
Social learning theory focuses on the role of observation and social interactions in learning
Cognitive development theory focuses on how individuals' thinking processes change with age
Information-processing theory focuses on the cognitive processes involved in perception, attention, memory, and problem-solving
Sociocultural theory and ecological systems theory focus on the influence of social and cultural contexts on development

Bioecological Model

Microsystem: individual
Mesosystem: family, childcare, neighborhood
Exosystem: friends, workplace, community, health services
Macrosystem: overarching values, laws, and customs

Periods of Human Development

Prenatal: Conception to birth
Infancy and toddlerhood: Birth to 2 years
Early childhood: 2-6 years
Middle childhood: 6-11 years
Adolescence: 11-18 years
Early adulthood: 18-40 years
Middle adulthood: 40-65 years
Late adulthood: 65 to death

Occupational Perspectives on Health (OPH)

Doing: active or passive engagement in occupation
Being: time for rest and reflection
Becoming: reaching one's potential and achieving desired outcomes
Belonging: feeling a sense of connection and belonging within a community

Transactional Relationships

Participation in occupations is influenced by:
- Individual's social contexts
- Engagement in family, cultural, and community activities
- Societal and political norms
- Physical, psychological, and social-emotional trauma

Occupational-Centered Lens

Top-down approach: Disability first, referral-based
Partners with family, child, and caretakers
Aims to improve occupational performance within the child's context
Bottom-up approach: Person-first, assessment-based
Focuses on identifying strengths and skills to build upon

Occupational Science

Studies human activity and occupations
Examines the benefits of participation in occupation
Seeks rationale for occupation selection
Explores the significance and meaning of human activity
Recognizes that development is not linear or sequential
Emphasizes the need for quantitative evaluation to generalize findings

Occupational Injustices

Occupational deprivation: lack of access to occupations due to factors outside one's control
Occupational apartheid: Limiting participation in occupations based on factors such as age, race, ability, or ethnicity
Occupational marginalization: exclusion from participation based on social norms
Occupational imbalance: spending too much time on one occupation at the expense of others
Occupational alienation: lack of meaning and purpose in work.

Just Right Challenge

Challenging and motivating tasks that are not too difficult or easy

Occupational-Centered Models vs. Frames of Reference

Occupational-Centered Models:
- Considers unique human features and values
- Focuses on strengths, challenges, and goals
- Uses consistent terminology, principles, assessments, and interventions
Frames of Reference:
- Connect theory to practice and intervention
- Provides structure for interventions and activities

Dynamic Systems Theory

Performance and action patterns emerge from interactions and collaborations between internal and external systems

Experience-Expectant Brain Growth

Experiences encountered during critical periods of development
Positive experiences contribute to normal brain development
Negative experiences or lack of opportunities can lead to delays or cognitive deficits

Experience-Dependent Neuroplasticity

Brain changes based on experiences throughout life
"Use it or lose it"
"Use it and improve it": practicing skills
Specificity: targeting specific areas for improvement
Repetition, intensity, time, salience, transference, and interference are influences on neuroplasticity.

Reflexes

Demonstrate the functionality of the nervous system
Typically disappear over time.

Stages of Sensory-Motor Development

Neonatal (0-3/4 months): Organizing sensory systems
4-6 months: Increasing head strength, more sensory exploration, rudimentary sitting
6-12 months: More object control, development of vocabulary through play and association of words with actions

Body Growth

Height: Doubles in the first year, increases by 75% by age two
Weight: Doubles by five months, triples by one year, quadruples by two years

Body Proportions

Cephalocaudal Trend: Head grows faster in utero, head is ¼ of body length at birth, legs are 1/3 of body length
Proximodistal Trend: Head, chest, trunk, limbs, hands, and feet develop in this sequence

Skeletal Growth

Determined through X-rays of long bones
Cartilage plays a role in bone development
Girls experience faster skeletal growth and maturation than boys

Arousal and Sleep

Rapid brain growth in the first two years requires significant sleep
Sleep needs decrease with age
Cultural considerations influence sleep patterns.

Growth Influences

Heredity
Nutrition: 25% more caloric intake needed to support growth
Breastfeeding: Provides immunity, socialization through holding, and bonding
Malnutrition: Long-term impacts on organ development

Learned Behaviors

Classical Conditioning: Learning through associating a neutral stimulus with a natural reflex
Operant Conditioning: Learning through feedback, reinforcement, and punishment
Habituation: Gradual decrease in attention to a repeated stimulus
Imitation: Learning by observing and copying behavior

Perception Development

Hearing:
- Preferences emerge by 4-7 months
- Ability to distinguish musical phrasing and types of music by 6-7 months
- Recognize songs by 12 months
Speech Perception:
- Newborns prefer speech sounds to non-speech sounds
- Recognize syllable stress in native language by 5 months
- Recognize speech sound patterns and clusters by 6 months
Visual Perception:
- Infants prefer faces and familiarity
- Respond to emotions by five months
- Wider range of emotions and expressions recognized by 7 months
- Beginning with a narrow focus and then transitioning to more refined attention
Depth Perception:
- Blink reflex emerges at 2-3 weeks
- Binocular vision begins around 2-3 months
- Awareness of 3D and partially hidden objects by 5-7 months
- Intermodal Perception: Integration of multiple sensory stimuli

Imitation

Deferred Imitation: Recall of novel actions for 1-6 days (6-9 months)
Inferred Imitation: Imitating actions with purpose and efficiency, attempting to perform actions as expected (12-18 months)

Autism Spectrum Disorder (ASD)

Brain Development: Larger brains in one-year-olds with ASD, excessive growth in the prefrontal cortex
Speech and Language Processing: Deficient left-hemisphere response to speech sounds leading to impacts on communication
Amygdala: Emotional processing is affected in individuals with ASD
Connections Between Amygdala and Temporal Lobes: Difficulty interpreting facial expressions

Cerebral Palsy (CP)

Condition arising from rapid myelination of the sensory and motor tracts and CNS structures
Most cases (70-80%) occur prenatally, some during birth, and others postnatally up to two years of age.
Group of permanent disorders affecting movement and posture due to non-progressive disturbances in the developing brain.
