Chunking01:12

Chunking

516
Chunking is a powerful cognitive technique that improves short-term memory retention by organizing information into smaller, more manageable units. The brain, limited by working memory capacity, can more easily process and store information when it is divided into "chunks" rather than presented as discrete, unrelated elements. Chunking is especially useful when dealing with large amounts of information, such as numerical sequences, words, or complex ideas.
The principle behind chunking...

Cognitive Learning01:21

Cognitive Learning

1.5K
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Learning Disabilities

730
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Information Processing Approach01:30

Information Processing Approach

734
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Higher Mental Functions of Brain: Learning and Memory

2.3K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Working Memory01:24

Working Memory

1.2K
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

  • Educational Psychology
  • Instructional Design

Background:

  • Didactic lectures often impose a high cognitive load on learners.
  • This excessive load can stem from the content itself or its presentation.
  • High cognitive load impedes the ability to learn and retain information effectively.

  • To summarize the science behind cognitive load in educational presentations.
  • To identify practical strategies for reducing cognitive load.
  • To enhance long-term information retention in learners.

Main Methods:

  • Review of cognitive load theory principles.
  • Analysis of presentation design elements impacting cognitive load.
  • Identification of evidence-based techniques for simplifying content delivery.

Main Results:

  • Cognitive load is influenced by content complexity and presentation methods.
  • Specific presentation techniques can significantly reduce extraneous cognitive load.
  • Reduced cognitive load correlates with improved long-term memory recall.
