Cognitivism01:17

Cognitivism

1.4K
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...

Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

228
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Working Memory01:24

Working Memory

133
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...

High-Level and Low-Level Awareness

247
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

30
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...

Parallel Processing01:20

Parallel Processing

145
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Summary
This summary is machine-generated.

Thirty years later, research confirms bilingualism impacts nonverbal cognitive abilities and selective attention. However, the idea that specific language processing mechanisms drive these effects is no longer supported.

Area of Science:

  • Cognitive Psychology
  • Neuroscience of Language
  • Bilingualism Studies

Background:

  • The study revisits a 1992 chapter on the cognitive effects of bilingualism, a field then in its early stages.
  • It evaluates the enduring validity of claims made about bilingualism's cognitive impact.

Purpose of the Study:

  • To reassess the validity of previously proposed cognitive effects of bilingualism.
  • To examine the continuity, nonverbal domain effects, and attentional mechanisms linked to bilingual experience.

Main Methods:

  • Re-evaluation of arguments presented in a 1992 contribution to a volume on bilingualism.
  • Review of three specific claims regarding cognitive changes in bilingual individuals.

Main Results:

  • The claims that bilingualism affects nonverbal domains and that these effects are continuous (not categorical) remain largely valid.
  • Selective attention is confirmed as a key explanatory factor for cognitive change in bilinguals.
  • The hypothesis that specific linguistic processing mechanisms transfer to other domains is rejected.

Conclusions:

  • Bilingual experience demonstrably influences nonverbal cognitive functions and relies on selective attention.
  • The underlying mechanisms driving these cognitive changes in bilinguals are not solely tied to specific linguistic processing transfers.
