Language and Cognition

Language and Cognition

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

Higher Mental Functions of the Brain: Language

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...

Working Memory

Working Memory

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 information.

Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Area of Science:

Neuropsychology
Cognitive Psychology
Psychometrics

Background:

Executive function measurement has a long history in neuropsychology.
Computerized tests offer standardized assessment of cognitive abilities.
The Psychology Experiment Building Language (PEBL) provides a platform for developing such tests.

Purpose of the Study:

To profile lifespan behavior on four PEBL computerized executive function tests.
To compare PEBL test performance with non-PEBL versions.
To validate PEBL tests as research tools for executive functions.

Main Methods:

Participants (N=1,223, ages 5-89) completed PEBL versions of Trail Making Test (pTMT), Wisconsin Card Sort Test (pWCST), Tower of London (pToL), and a time estimation task (Time-Wall).
Age-related effects were analyzed across the lifespan.
Performance patterns were compared to previous non-PEBL test data.

Main Results:

Significant age-related effects were observed across all four tests.
Performance changes were particularly notable from childhood through adulthood.
Age-related slowing was evident in adulthood for pToL and pTMT.

Conclusions:

The PEBL computerized executive function tests demonstrate age-related behavioral profiles across the lifespan.
These findings support the validity and versatility of PEBL tests for research.
PEBL tests offer valuable tools for studying executive functions in diverse age groups.
