Lifespan Development - Chapter 10 Flashcards
Developmental Psychology
Developmental psychology is the study of human physical, cognitive, social, and behavioral characteristics across the lifespan
Principles of Growth & Development
Continuous sequential process from conception to death
During the first year, growth is very rapid
Growth levels off during the preschool and elementary-school years
Growth is rapid in early adolescence
Physical Growth Trends
Proximodistal trend
Cephalocaudal trend
Epiphyses
Research Design in Developmental Psychology
Cross-sectional design
Longitudinal design
Nature Nurture Influences
Both are important in shaping development It’s not an “either-or” issue any longer Gene-environment interaction
Impact of genes on behaviour depends on the environment where behaviour develops
Gene-Environment Interaction
The impact of genes on behaviour depends on the environment in which the behaviour develops
Nature via Nurture
Genetic predispositions can drive us to select and create particular environments, leading to the mistaken appearance of a pure effect of nature
Gene Expression
Some genes “turn on” only in response to specific environmental events
Historical/cultural and societal contexts
Transmission of patterns of beliefs, values, customs and skills to younger generations - reflective of historic and cultural contexts
Domains of Development
Physical domain - considered to involve:
Physical changes - height, weight, strength, etc.
Neurological development
Gross motor skills
Fine motor skills
Sensory development
Cognitive domain – considered to involve:
Intellectual - thinking, acquiring new knowledge, attention, memory, reasoning, and problem-solving skills
Language domain - often considered to be within the Cognitive domain
Expressive language (speaking)
Receptive language (understanding what others are saying)
Verbal and non-verbal
Social-Emotional domain - considered to involve:
Sense of belonging
Interactions with others (navigate social interactions - for example, cooperation)
Forming relationships - family, friends, community
Being able to use and understand social skills and social cues
Experience, express, and manage own emotions
Understand the emotions of others
Prenatal Development (stages)
Period of Zygote (Weeks 0-2)
Conception (sperm fertilizes ovum).
Zygote attaches to uterine wall.
Embryonic Stage (Weeks 3 - 8)
Prenatal Brain Development
Between day 18 and approximately 180 days (6 months), neurons grow at an incredible rate
Up to 250,000 neurons per minute at times
Factors Affecting Prenatal Development
Alcohol consumption, smoking, drugs, and chicken pox durning pregnancy
Preemies (preterm infants)
Preterm infants are born earlier than 36 weeks.
Children born at 25 weeks have a little better than 50% chance of surviving.
However, because fetal development happens quickly, children born at 30 weeks have a 95% chance of survival.
Supports for New Parents of Preemie
Kangaroo Care
Infants Brain Development
Myelination begins prenatally and accelerates through infancy and childhood, and then continues gradually for several decades
Synaptic Development (2 key processes)
Synaptogenesis - the forming of new synaptic connections.
Synaptic pruning the loss of weak nerve cell connections
Infants - Sensory Development
Human infants are born almost completely helpless and require extended care as they develop their senses, strength, and coordination.
Newborns will imitate the facial expressions of others.
Infants Motor Development
Infants are born with a large set of automatic motor behaviors (reflexes)
Sucking and rooting reflexes are essential for feeding
Cognition
Activity of knowing and the mental processes used to acquire knowledge and solve problems
Cognitive Development
Changes that occur in mental skills and abilities over the course of life
