Human Development
Scientific study of age-related changes across physical, cognitive, social and behavioural domains
Multidisciplinary
Includes developmental psychology
Developmental Psychology
The study of how behaviour and mental processes change over a lifespan
ex. language and self-control development
Lifespan Perspective
Changes occur within the entire duration of the human lifespan (not just child-adulthood)
Post-hoc Fallacy
The false assumptions that because on event occurred before another, it must have caused it
ex. parent notices ADHD symptoms in a child after several years of playing video games
Bidirectional Influences
Parents influence children; Children influence parents
ex. Temperaments & personality relationship with parenting style
Critical Periods
Specific periods in development when an organism is especially sensitive to the presence/absence of some particular kind of experience
Sensitive Period
A span of months or years during which a child may be particularly responsive to specific forms of experience or particularly influenced by their absence
Epigenome
The sum total of inherited and acquired molecular modifications to the genome that leads to changes in gene regulation without changing the DNA sequence of the genome
Cohorts
Groups of individuals who are born within a particular span of years and share the same historical experiences at the same point in their development
Cohort Effect
Effect observed in a sample of participants that results from individuals in the sample growing up at the same time
Can confound the ability to attribute differences to age
Cross-sectional Research Design (definition, advantage, disadvantages)
Research focused on age-related changes
Investigates people of different ages at a single point in time
Longitudinal Research Design (definition, advantage, disadvantages)
Research focused on age-related changes
Investigates development in the same group of people on multiple occasions over time
Cohort-Sequential Research Design (2)
Research focused on age-related changes
Investigates several age cohorts followed and tested longitudinally

Neuronal Proliferation
Neurons are generated
Migration
Movement of brain cells to permanent location
Teratogens (4)
Environmental factors that can exert a negative impact on prenatal development
ex. Alchohol ➡️ FASD
Genetic Disorders (3)
Result from DNA mutations or wrong amount of genetic material
