Language experience predicts semantic priming of lexical decision
1Department of Psychology, University of Winnipeg.
Summary
This study introduces a novel method for creating personalized semantic memory models using individual news consumption data. These corpus-specific models accurately predict how news readership influences cognitive processes like semantic priming.
Area of Science:
- Cognitive Science
- Computational Linguistics
- Psychology
Background:
- Computational models of semantic memory typically use generalized language corpora.
- This approach limits the ability to model individual differences in semantic representations.
- Previous research has not validated corpus-specific predictions for semantic memory.
Purpose of the Study:
- To develop and validate a method for generating corpus-specific semantic representations.
- To investigate if individual news readership influences semantic representations.
- To test if these representations predict differential priming effects.
Main Methods:
- Utilized internet news sites as corpora to generate personalized semantic representations.
- Recruited subjects based on their specific news site readership.
- Administered lexical decision tasks to measure priming effects.
Main Results:
- Identified word similarities that are specific to particular news sites.
- Demonstrated that news site-specific semantic representations successfully predict priming effects.
- Showed that differential priming effects correlate with news readership.
Conclusions:
- Corpus-specific semantic representations are feasible and valuable.
- Individual language experiences, reflected in news consumption, shape semantic memory.
- This approach offers a pathway to more personalized cognitive modeling.

01:27Language and Cognition
532
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.

01:28Automatic Processing and Automatic Social Behavior
88
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

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.

First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

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...
