Working Memory01:24

Working Memory

977
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...

Introduction to Cognitive Psychology

2.8K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

High-Level and Low-Level Awareness

799
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Information Processing Approach01:30

Information Processing Approach

624
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...

Language and Cognition01:27

Language and Cognition

836
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitivism01:17

Cognitivism

3.2K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Media Studies

Background:

  • American youth average 7.5 hours daily with media, with 29% engaging in media multitasking.
  • Media multitasking (MMT) is a global phenomenon, particularly prevalent among developing children and young adults.
  • Understanding the neurocognitive profiles of MMTs is crucial due to their developing brains.

Purpose of the Study:

  • To review evidence on the neurocognitive, psychosocial, and neural differences in heavy media multitaskers (MMTs).
  • To examine the relationship between MMT and academic outcomes.
  • To inform policy and practice regarding media use in learning environments.

Main Methods:

  • Systematic review of existing research on media multitasking.
  • Analysis of studies examining cognitive domains, psychosocial behavior, and neural structure in MMTs.
  • Investigation of the impact of MMT on academic performance.

Main Results:

  • Heavy MMTs exhibit cognitive differences, such as poorer memory.
  • Individuals engaging in MMT show altered psychosocial behavior, including increased impulsivity.
  • Neural structure differences, like reduced anterior cingulate cortex volume, are observed in MMTs.
  • Media multitasking during learning correlates with negative academic outcomes.

Conclusions:

  • Heavy media multitasking is associated with distinct cognitive, psychosocial, and neural profiles.
  • Media multitasking during learning may adversely affect academic achievement.
  • Further research is needed to establish causality between MMT and observed differences.
  • Findings underscore the importance of considering concurrent media stream engagement in educational contexts.
