E3--Unit 10
Do children use one strategy or multiple strategies in problem solving?
They often use more than one strategy. Most children benefit from generating a variety of alternative strategies and experimenting with different approaches to a problem, discovering what works well, when, and where.
metamemory
individuals' knowledge about memory
study found that 3-11 y/o had better....
inhibitory control
Divided attention.
involves concentrating on more than one activity at the same time
Thinking
involves manipulating and transforming information in memory
Critical thinking
involves thinking reflectively and productively, and evaluating evidence.
Working memory
is a kind of mental "workbench" where individuals manipulate and assemble information when they make decisions, solve problems, and comprehend written and spoken language
Short-term memory
is a memory system with a limited capacity in which information is usually retained for up to 15 to 30 seconds unless strategies are used to retain it longer.
Long-term memory
is a relatively permanent and unlimited type of memory. People are usually referring to long-term memory when they talk about "memory."
Selective attention
is focusing on a specific aspect of experience that is relevant while ignoring others that are irrelevant
Sustained attention
is the ability to maintain attention to a selected stimulus for a pro- longed period of time.
Strategy construction
is the creation of new procedures for processing information.
Attention
is the focusing of mental resources. It improves cognitive processing for many tasks
Encoding
is the process by which information gets into memory.
Dishabituation
is the recovery of a habituated response aft er a change in stimulation.
Memory
is the retention of information over time.

in aspects of the infant's life and increases infant's ability to learn from other people
Adolescence is an important transitional period
in the development of critical thinking
Metamemory
includes general knowledge about memory, such as knowing that recognition tests (such as multiple- choice questions) are easier than recall tests (such as essay questions).
from 18 months to 3 years old, children begin to understand 3 mental states:
-perceptions -emotions -desires
most important for 4- to 11-year-old children's cognitive development and school success:
-self control/ inhibition -working memory -flexibility
orienting/investigative process
. This process involves directing attention to potentially important locations in the environment (that is, where) and recognizing objects and their features (such as color and form) (that is, what) .
From what months of age, can infants deploy their attention more flexibly and quickly?
3-9 months of age
children younger than _____ y/o do not think its possible to have a false belief
4
After the age of _______, children pay more attention to features relevant to performing a task or solving a problem, such as the directions.
6 or 7 y/o
Fuzzy trace theory states that when individuals encode information, they create two types of memory representations....
: (1) a verbatim memory trace, which consists of precise details; and (2) a fuzzy trace, or gist, which is the central idea of the information. According to this theory, older children's better memory is attributed to the fuzzy traces created by extracting the gist of information.
executive function
An umbrella-like concept that consists of a number of higher-level cognitive processes linked to the development of the brain's prefrontal cortex. it involves managing one's thoughts to engage in goal- directed behavior and to exercise self-control.
when do children learn to solve problems?
As children learn more about what is relevant to a problem and learn to encode the relevant information, they are better at using rules in problem solving.
Changes in metacognition for adolescents:
Compared with when they were children, adolescents have an increased capacity to monitor and manage cognitive resources to effectively meet the demands of a learning task. This increased metacognitive ability results in cognitive functioning and learning becoming more effective.
What are the basic components of memory?
Encoding, storage, and retrieval are the basic processes required for memory. Failures can occur in any of these processes.
What changes in the brain are linked to infants' memory development?
From about 6 to 12 months of age, the maturation of the hippocampus and the surrounding cerebral cortex, especially the frontal lobes, makes the emergence of explicit memory possible explicit memory increases within the 2nd year as folds are maturing and more connections are established
"How competent are adolescents at making decisions?
Older adolescents are described as more competent than younger adolescents, who in turn are more competent than children. Compared with children, young adolescents are more likely to generate different options, examine a situation from a variety of perspectives, anticipate the consequences of decisions, and consider the credibility of sources.
strategies for decision making for adolescents?
One strategy for improving adolescent decision making in such circumstances is to provide more opportu- nities for them to engage in role playing and group problem solving. Another strategy is for parents to involve adolescents in appropriate decision-making activities.
dual-process model
States that decision making is influenced by two systems, one analytical and one experiential, that compete with each other. In this model, it is the experiential system—monitoring and managing actual experiences—that benefits ts adolescent decision making.
what types of attention are very important aspects of adolescent cognitive development?
Sustained and executive attention

habituation
decreased responsiveness to a stimulus aft er repeated presentations of the stimulus.
In early childhood, executive function especially involves:
developmental advances in cognitive inhibition (such as inhibiting a strong tendency that is incorrect) cognitive flexibility (such as shifting attention to another item or topic) goal-setting (such as sharing a toy or mastering a skill like catching a ball), delay of gratification (the ability to forego an immediate pleasure or reward for a more desirable one later)

Unlike Piaget, however, developmentalists who take an information-processing approach do not see development as .....

In early adolescence, children begin to understand that ....
people can have ambivalent feelings. They start to recognize that the same person can feel both happy and sad about the same event. They also engage in more recursive thinking: thinking about what other people are thinking about.
According to schema theory,
people mold memories to fit information that already exists in their minds. This process is guided by schemas
Executive attention involves .......
planning actions, allocating attention to goals, detecting and compensating for errors, monitoring progress on tasks, and dealing with novel or difficult circumstances.
How can processing speed be assessed?
reaction-time task in which individuals are asked to push a button as soon as they see a stimulus such as a light. Or individuals might be asked to match letters or match numbers with symbols on a computer screen.
Implicit memory .
refers to memory without conscious recollection—memories of skills and routine procedures that are performed automatically, such as riding a bicycle
Automaticity
refers to the ability to process information with little or no effort. Practice allows children to encode increasing amounts of information automatically.
explicit memory
refers to the conscious memory of facts and experiences
rehersal is a better strategy for what type of memory?
short term memory
