Unit 3a: Development Flashcards
Lifespan Development
study of how individuals grow, change, and remain the same throughout their entire lives, from conception to death.
Nature and Nurture
interplay between genetic inherited traits and enviornments influences in shaping an individual’s development.
Stability and Change
stability proponents might argue that personlaity traits persistfrom infancy to adulthood
change proponents might argue that our personalities are modified by interactions with family and friends
Discontinuous Development
changes occur in distint stages, each with its own unique characterisitic
Continous Development
changes occur steadily and progressively, without sudden shifts of stages.
Teratogens
substances or environmental factors that can cause harm to a developing fetus or embryo.
- can lead to birth defects or developmental problems.
Reflexes
involuntary, automatic responses to specific stimuli, present at birth and often serving as survivial mechanisms.
Rooting Reflex
newborn’s automatic response to turn their head and open their mouth toward a touch on their cheek or mouth, aiding in breastfeeding.
Gross Motor Coordination
ability to perform movements that involve large muscle groups, such as those in the arms, legs, and torso.
Fine Motor Coordination
ability to make precise movements using small muscle groups, typically involving the hands and the fingers.
Maturation
process of development in which an individual matures or reaches full funcionality.
- based on genetic instructions
- milestones
Critical Periods
specific time frames during development when an organism is particularly sensitive to certain environmental stimuli.
- certain skills/abilities are most readily acquired
- if appropriate stimuli are not received, there may be difficulty developing those skills later.
Sensitive Periods
similar to critical periods but less rigid; sensitive periods are times when an individual is more responsive to certain types of enviornmental conditions.
Imprinting
in some animals, the young will immediately form a familial attachment to whatever animal/human that is present.
- an example of a critical period
Growth Spurt
rapid increase in physcial growth and development.
- infanct
-adulthood.
Puberty
period of physical and hormonal changes that lead to sexual changes that lead to sexual maturation and the ability to reproduce.
Primary Sex Characteristics
reproductive organs/structures involved in reproduction.
- ovaries
-testes
Secondary Sex Characteristics
physical characteristics not for reproduction
Menarche
The 1st menstrual period in females, signaling, the onset of reproductive capability.
age: 11-14 (mean 12.4)
Sepemarche
The start of sperm production in males at puberty, signaling the onset of reproduction capability.
age: 12-15 (mean 13.5)
Menopause
natural cessation of menstruation and the end of reproductive capabilities in women.
no more periods
Piaget’s Theory
beleived that intellectual development is driven by biological development amidst experiences with the enviornment.
Stage 1: Sensorimotor Stage
0-2 years
infants learn about the world through their senses and actions.
develop object permanence
Object Permanence
understanding that objects continue to exist even when they are not visible.
- develops between 4-7 months
