Utvecklingspsykologi Flashcards
Regulation factor
A substance in the environment that disables the inhibition that non-protein-coding DNA exerts on the coding DNA.
Pleiotropic
Genes that code for more than just one trait
Range of reaction
The span within which a person’s abilities may develop based on the environment to which their genes are subjected.
Canalization
When the range of reaction is narrow. The pathways through which a canalized trait may be developed are few.
Passive genetic-environmental correlation
Parents with certain genetic predispositions may create homes that suit these predispositions and encourage the inherited ones of their children.
Evocative genetic-environmental correlation
Inborn tendencies that are expressed and responded to by the social environment might be reinforced, creating a circuit where the tendency is strengthened and the genetic predisposition is magnified.
Active genetic-environmental correlation
Genetic predispositions encourage us to seek out environments in which these predispositions are valuable. People with aggressive predispositions tend to sign up for martial arts classes instead of chess. This niche picking magnifies the genetic predisposition.
Heritability factors
Percentage estimates of the extent to which heritability contributes to a particular ability or type of behavior.
Equal environment assumption
The assumption on which twin studies depend - that twin studies receive the same environmental exposure.
Candidate gene
A gene that codes a specific trait.
Polygenicity
A trait is influenced by many genes
Germinal stage
Period of the zygote
Zygote
Fertilized egg
Gestation
The period during which development in the uterus occurs
Amniotic sac
Thin membrane containing amniotic fluid that protects the embryo from shocks and physical damage. Similar to CSF in the brain.
Cephalocaudal development
Development proceeding from head to trunk and legs.
Proximal-distal development
Proximal(towards the centre) distal (away from the centre).
This development describes the development starting in the centre and moving outwards towards the arms and legs
Foetus
From third month of gestation to delivery
Teratology
The study of the origins of prenatal abnormalities
Congenital
Present from birth, with birth
Teratogen
Environmental factors that can lead to congenital abnormalities
Chromosomal abnormality
Morphological or numerical abnormalitity in chromosomes, either autosomes or sex chromosome or both
Teratogenesis
The process causing defects and abnormalities in embryos and foetuses
Perinatal complications
Issues that arise shortly before, during or shortly after delivery
Catch-up growth
Catching up to normal physical growth
Catch-up growth
Catching up to normal physical growth
Apoptosis
Programmed cell death
Ontogeny/Ontogenisis
The process of an organism’s formation, from the fertilization of an egg to adulthood.
Phylogeny
The history of evolution of a species.
Proliferation (Biology)
Rapid reproduction of cells
Object constancy
Recognizing an object at varying distances, under different lighting and at varying angles
Natural pedagogy
Evolution has taught infants to innately exhibit certain behaviors. One of which is to prefer to direct gaze towards faces whose eyes are directed towards the infant.
Predictive control
We are able to predict immediate future events and plan accordingly, coordinating motoric movements to adapt in our ever-changing environments.
This develops as an interplay between neural development and experience.
Overextension
Using one word for too many objects.
Underextension
Using one word in a restricted and individualistic manner.
Holophrase
Single word utterances that seem to represent a complete thought.
Telegraphic speech
Few words used to convey messages, sort of like telegrams used to be.
Core knowledge
Knowledge that we are born with. (Evolutionary perspective) We have knowledge systems with specific applications. Some things we are born with and are able to use right from the beginning. The development is domain-specific.
Domain-specific
Domain general
Domain specific -The acquisition of a specific skill is facilitated by a specific cognitive skill. I.e mathematics is learned through one cognitive function, and language through another.
Domain general: The acquisition of different skills are facilitated through the same broad set of cognitive skills. Language and mathematics are underlined by the same cognitive functions.
Assimilation
Applying what you know from before to new experiences.
These new experiences are then added to existing schemas that expand.
Accomodation
Creating new ways to relate to new knowledge. Often by altering our schemas that we put this newfound knowledge into.
Disequilibrium
When there is a cognitive unbalance. This leads to accomodation.
Sensomotoric stage 0-2 years
Children explore their surroundings using their physical abilities. They may crawl around, put things in their mouth, and use haptic perception to learn about their reality. But a notion of object permanence emerges during this stage.
The physical movements become goal-oriented.
This stage is sublined by 6 undercategories.
Pre-operational 2-6 years
The child is not yet able to logically process objects. But they are able to think in symbolic terms. eg. pictures and words to represent the world. They can think and process separate mental objects but they cannot use logic to transform, separate or combine ideas.
Concrete Operational stage 6-12 years
The child is able to use logic to process ideas and objects. But they cannot yet logically process abstract ideas that do not have a concrete presence. Are able to understand concepts such as reversibility, conservation and classification.
During this stage decentration occurs aswell.
Formal operational stage 12 years-
Able to use logical processing to process abstract notions aswell that do not have a concrete presence. Complex logical abilites form, judgement is developed and conceptualization develops.
Testing hypothesis, solving problems. Imagining alternative realities.
Decentration
A shift of center of perception away from the child. This is when the egocentricism starts to fade away and children are able to think of other’s perceptions as well.
Conservation
The ability to understand that the volume of something doesn’t change just because it’s appearence does. Pouring water from one beaker that differs in appearence to the next one does not change the volume
Reversibility
The understanding that allows the reversing of a sequence of events or restores the changed state of affairs into the original condition. Pouring a glass of milk into a bottle can be reversed by pouring the milk back into the bottle.
Zone of Proximal Development
The area in which a childs abilities are developed. Difference between what they know and what they can learn with adult guidance or capable peers.
Mediator
A tool that is used to support and extend cognition. Language is one mediator
Scaffolding
A learning technique in which the teacher adjusts their participation and guidance in accordance with the knowledge and abilities of the learner.
Reciprocal instruction
Peer to peer instructions where the teacher either uses scaffolding or is involved and actively learning.
