Module 5 - Conceptual Development Flashcards
General ideas or understandings that can be used to group together objects, events, qualities, or abstractions that are similar.
Concepts
Infant’s visual system
They have poor visual acuity (sharpness), resulting in blurry vision until about 8 months
They also need to develop control over their eye muscles, but can track objects with their eyes by 3 months (if not earlier).
Lastly, infants also have limited colour perception at birth, and therefore prefer stimuli with high contrast.
Three common eye gaze methodologies that developmental psychologists use to study infant cognition
Habituation
Preferential looking
Violation of expectation
Habituation
Using eye gaze, researchers record time to habituate - decreased response to a stimulus after repeated exposure.
Habituation is commonly used to study infant visual development (e.g., can they perceive tiny differences in perceptual stimuli, can they discriminate colours, etc), as well as conceptual and cognitive development.
Even very young infants have visual perception and control over their eye movements, making this method an ideal tool to use during infancy.
Generally, the infant must be at least 3 months to obtain reliable data.
research consistently demonstrates that faster habituation time during infancy predicts
later intelligence (and is often a better predictor of later IQ than infant IQ tests!).
Concepts help us…
understand the world and act effectively in it by allowing us to generalize from prior experience
What are the themes in research on conceptual development
1) nature and nurture
2) active child
3) how change occurs
4) sociocultural context
Nature and Nurture theme in conceptual develoment
Children’s concepts reflect the interaction between their specific experiences and their biological predispositions to process information in particular ways.
Active child theme in conceptual development
From infancy onward, many of children’s concepts reflect their active attempts to make sense of the world.
How change occurs theme in conceptual development
researchers who study conceptual development attempt to understand not only what concepts children form but also the processes by which they form them.
Sociocultural theme in conceptual development
the concepts we form are influenced by the society in which we live.
What do Nativists believe about conceptual development?
That innate understanding of basic concepts plays a central role in development.
They argue that infants are born with some sense of fundamental concepts, such as time, space, number, causality, and the human mind, or with specialized learning mechanisms that allow them to acquire rudimentary understanding of these concepts unusually quickly and easily.
nurture plays an important role in helping children move beyond this initial level of conceptual understanding, but not in forming the basic understanding.
What do empirists believe about conceptual development?
That nature endows infants with only general learning mechanisms, such as the ability to perceive, attend, associate, generalize, and remember.
Within the empiricist perspective, the rapid and universal formation of fundamental concepts such as time, space, number, causality, and mind arises from infants’ massive exposure to experiences that are relevant to these concepts
2 groups of developmental concepts
1) used to categorize the kinds of things that exist in the world—human beings, living things in general, and inanimate objects—and their properties.
2) involves dimensions used to represent our experiences: space (where the experience occurred), time (when it occurred), number (how many times it occurred), and causality (why it occurred).
Infants and young children divide objects into three general categories:
inanimate objects
people
other animals
(they are unsure for many years whether plants are more like animals or more like inanimate objects)
children form innumerable more specific categories such as:
vehicles, tools, furniture, sports equipment, and endless others.
Children tend to organize these categories of objects into category hierarchies
Category Hierarchies
a category that is organized by set–subset relations, such as animal/dog/poodle
Dishabituated
looking time increased.
How early can infants form categories?
Even in first months of life.
perceptual categorization
the grouping together of objects that have similar appearances
Infants frequently use this.
Category Hierarchies
Superordinate, subordinate, basic
superordinate level
the general level within a category hierarchy, such as “animal” in the animal/dog/poodle example
subordinate level
he most specific level within a category hierarchy, such as “poodle” in the animal/dog/poodle example
basic level
the middle level, and often the first level learned, within a category hierarchy, such as “dog” in the animal/dog/poodle example
