Language and Cognition01:27

Language and Cognition

332
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.

Higher Mental Functions of the Brain: Language

768
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Cognitive Development During Adulthood

65
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Cognitivism

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...

Cognitive Dissonance01:38

Cognitive Dissonance

32.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

106
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Area of Science:

  • Neuroscience
  • Psycholinguistics
  • Speech and Language Pathology

Background:

  • Aphasia, a language disorder post-brain injury, often impairs sentence comprehension.
  • Cognitive control plays a role in overcoming processing challenges, but its role in aphasia comprehension is understudied.

Purpose of the Study:

  • To investigate conflict adaptation in individuals with aphasia.
  • To determine if enhancing cognitive control improves sentence comprehension in aphasia.

Main Methods:

  • Four participants with mild aphasia underwent eye-tracking during auditory Stroop and sentence-picture matching tasks.
  • Experimental conditions manipulated auditory and sentence congruency to assess conflict adaptation.

Main Results:

  • One participant demonstrated conflict adaptation, showing faster reaction times and improved eye-tracking patterns.
  • Another participant exhibited modulation of sentence processing by incongruent auditory stimuli.

Conclusions:

  • This is the first study to observe conflict adaptation in sentence comprehension in individuals with aphasia.
  • Results suggest cognitive control enhancement may be a viable treatment strategy for some aphasia patients.
  • Eye-tracking revealed subtle effects not evident in overt behavioral measures.
