Resource-independent negative effects of foreign language on analogical problem solving

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Problem Solving

Background:

• Analogical problem solving is crucial for complex tasks.
• Foreign language use is known to impede cognitive processes.
• Previous research suggests language affects problem-solving, but the underlying mechanisms require further investigation.

Purpose of the Study:

• To investigate whether the negative effect of foreign language on analogical problem solving is resource-independent.
• To determine if cognitive load moderates the impact of language on solving problems by analogy.

Main Methods:

• Participants engaged in analogical problem-solving tasks.
• Target problems were presented in either native or foreign languages.
• A concurrent task was used to manipulate cognitive processing resources.

Main Results:

• Individuals experienced greater difficulty solving problems in a foreign language compared to their native language.
• This deficit in foreign language problem-solving was observed irrespective of cognitive load.
• Performance was significantly better when problems were in the native language, even under reduced resources.

Conclusions:

• Foreign language processing significantly impairs analogical problem-solving ability.
• The detrimental effect of a foreign language on this cognitive skill operates independently of available processing resources.
• Cognitive load does not mediate the relationship between foreign language and analogical reasoning.
