Development Multiple Choice Test Flashcards
Cross-sectional research
Research one specific group, or compare two or more specific groups at the same time. PROS: It’s easy to control for random variables. It can be easily replicated. It is relatively inexpensive. It is good at telling you how people at different ages behave. CONS: It doesn’t show any change over time. It doesn’t account for cohort differences.
Cohort
A group of people born at the same historical time.
Longitudinal Research
Study the same group of people over a long period of time. PROS: You get a very large amount of info about the group. It is the only research method that can prove change over time. CONS: It is very expensive and time-consuming. It is hard to control for random variables (people moving away, dying, etc.). There is a high attrition rate.
Attrition
People leaving the study
Biographical Research
Also known as retrospective research, when you study the impact of an event in someone’s life after it happened. PROS: You can find out about unexpected phenomena. CONS: Memory is pretty unreliable as we may remember the event incorrectly. We also cannot account for many variables that influence up until the point of interest in the matter.
Jean Piaget
The groundbreaking developmental psychologist who tried to answer the questions, “What basic ideas do children have to know to correctly understand the world?” and “How do we learn those beliefs?” He did so by breaking down development into stages where different ideas appear in children that allow them to understand the world. He argued that we have thoughts even before learning a language. He believed children develop because of nature: we naturally progress though the stages and little can be done to influence when our thinking develops.
Lev Vygotsky
A lesser-known developmental psychologist who made important contributions as well. He argued that we do not think about things that aren’t coded in language. He believed children develop because of nurture: we are fundamentally shaped by our environment because we are constantly moving into new zones of proximal development. We can do things with some help, but not entirely on our own. Once we master one concept, we get help with the next and so on.
Object Permanence
The knowledge that things continue to exist even when you can’t see them anymore. This concept is critical for understanding the physical reality of our world.
Sensorimotor Stage
The first stage of cognitive development that lasts from birth to age 2 where we develop object permanence. At this stage, infants know the world mostly in terms of their sensory impressions and motor activity (the five senses).
Conservation
The principle that quantity remains the same even if the shape changes. This concept is critical for understanding the physical reality of our world.
Egocentrism –> Theory of Mind
The understanding that other people have other points of view (literally and metaphorically). The idea that other people have their own minds that are separate from ours. This is a critical concept for interpersonal relationships. Before theory of mind develops, children are egocentric, believing that everyone sees and thinks exactly what they are thinking.
Symbolic Thought
The understanding that one thing can represent something else. Ex. reading a map and knowing that the map represents a specific thing or area of the world.
What role does language play in our development of symbolic thought?
Piaget thought that language was indicative of symbolic thought. He assumed that, before we can talk, we have ideas, and then words get layered on top of those ideas. Vygotsky disagreed and said that we do not think about things that are not coded in thought. **There is no way to prove whether Piaget or Vygotsky is correct
Preoperational Stage
The second stage of cognitive development, lasting from age 2 to 6 or 7 where children grasp the ideas of conservation, theory of mind, and symbolic thought. This is also when a child learns to use language but doesn’t yet comprehend the mental operations of concrete logic.
Concrete Reasoning
A correct understanding of our physical world, but the reasoning is based in reality rather than abstraction.
Concrete Operational Stage
The third stage of cognitive development, lasting from ages 7-12 where children gain the mental operations that enable them to think logically about events. They can comprehend math transformations and conservation.
Abstract Thinking
The development of a theoretical or conceptual understanding of both earlier concepts and new concepts.
Formal Operational Stage
The fourth (and final) stage of cognitive development lasting from age 12 to adulthood where people begin to think logically about abstract concepts. There is also potential for mature moral reasoning.
Do we develop cognitively due to nature or nurture?
According to Piaget, we develop cognitively due to nature. He says that we naturally progress through the different stages of cognitive development (SM, P, C, F) and that there is very little that can be done to influence when our thinking develops.
On the other hand, according to Vygotsky, we develop cognitively more due to nurture. He says that we are fundamentally shaped by our environment because we are constantly moving into new zones of proximal development; when we can do or think about something with some help, but not entirely on our own. Once we master the concept, we get help with the next thing, and so on.
Zone of proximal development
People are increasingly ready to learn things at certain stages of life.
How do we know language acquisition is a function of both nature and nurture?
We know that language acquisition is a function of both nature and nurture because it is the complex interaction between the child’s innate (natural) capacities and the cognitive, linguistic, and social supports provided in the environment. Nature and nurture work together to help us learn, use, and understand language.
What evidence do we have for the interplay between nature and nurture in the cognitive development of language?
Nature:
- We can distinguish words from other sounds and can develop a broad schema for definitions. (Ex. Young children can put together sentences they’ve never heard before. They leave out the words that are irrelevant for conveying the meaning (and, the, etc.). Most children’s early words are nouns because they are the things that are relevant for coding a child’s world.)
- We can expand our vocabulary very quickly.
(Ex. Children know 25 words at ~15 months. By age 5, kids know 8-10,000 words which is almost all of the words you will ever know. Picking up vocabulary this quickly rarely happens for adults.)
Nurture:
- We do not develop concepts and ideas that we do not have words for
- Our words shape the way we think about vocabulary
What evidence do we have for the interplay between nature and nurture in the linguistic development of language?
Nature:
- We have to learn the rules of our language
Grammar → The rules of a language. Evidence shows that we actually understand grammar rules, and we aren’t just parrots. This is seen when most grammatical mistakes go uncorrected in young children, but they clearly internalize the rules. We can tell by the mistakes they make. Ex. “runned”, “eated”, etc. We learn the grammatical rules of the language, but our ability to figure out and apply the rules is innate (natural).
Nurture:
Babies are ready to learn any language
Phonemes → Perceptual unit that composes speech. They quickly begin to focus on their native language, and by about 12 months old, babies can only “hear” the sounds that are relevant or their native language.
- We learn the patterns of speech in our language, or auditory clues that something is a question vs a statement for example, with motherese
Motherese → A high-pitched, exaggerated way of speaking that we use when we talk to babies. Babies seem to prefer it, and this suggests that it is an adaptive pattern. It slows down our speaking so that babies can learn phrasing, etc.
What evidence do we have for the interplay between nature and nurture in the social development of language?
Nurture:
- Babies learn how to have conversations even before they can talk
Babble conversations → Back and forth between baby and caregiver, occurring before kids even know basic vocabulary. This seems to help shape what the child does innately (make sounds) in learned patterns of speech.
- Cultural patterns influence speech within the same language, and children learn how to USE the language differently. This impacts patterns of speech that persist over long periods of time.
- In the US, families of color are more likely to ask questions of their babies where the answer is unknown.
- In the US, white families are more likely to ask questions where the asker already knows the answer
Nature:
- Language is a fundamental part of the human experience, and it is our natural way of communicating with one another.
