Cognitivism

1.7K
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...

Brain Waves01:23

Brain Waves

2.0K
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

818
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...

Optimal Arousal Theory01:23

Optimal Arousal Theory

298
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Language and Cognition01:27

Language and Cognition

441
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.

High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

384
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...

Summary
This summary is machine-generated.

Alpha oscillations (brain waves) track cortical excitability, not just selective attention. Their modulation by various factors necessitates careful interpretation in cognitive research.

Area of Science:

  • Neuroscience
  • Cognitive Science

Background:

  • Alpha oscillations are linked to cortical suppression and selective attention.
  • Previous interpretations may oversimplify the role of alpha oscillations.

Purpose of the Study:

  • To question the specificity of alpha oscillations as solely a mechanism for selective attention.
  • To propose an alternative framework for understanding alpha oscillations.

Main Methods:

  • Review of existing literature on alpha oscillations and attention.
  • Analysis of dissociations between alpha activity and selective attention.

Main Results:

  • Identified inconsistencies between alpha oscillations and selective attention.
  • Proposed that alpha oscillations track cortical excitability, influenced by multiple factors.

Conclusions:

  • Alpha oscillations are modulated by diverse influences beyond selective attention.
  • Context-dependent interpretation is crucial for understanding alpha oscillations' cognitive roles.
  • Further research is needed to clarify the mechanistic basis of alpha oscillations across cognitive phenomena.
