Adults' reading comprehension: effects of syntactic complexity and working memory

Area of Science:

• Cognitive Psychology
• Neuroscience
• Linguistics

Background:

• Working memory is crucial for complex cognitive tasks like reading.
• Age-related cognitive decline can affect various aspects of memory and processing.
• Syntactic complexity in language presents a significant challenge for readers.

Purpose of the Study:

• To investigate the relationship between working memory capacity and reading comprehension across different age groups.
• To examine how syntactic complexity influences reading comprehension in younger and older adults.
• To determine the impact of age on working memory and reading performance.

Main Methods:

• Two experiments were conducted involving college students and older adults.
• Participants completed working memory tests, a standard reading comprehension test, and a syntax-focused reading test.
• A follow-up study retested older adults on a modified syntax comprehension task.

Main Results:

• Experiment I showed age-related declines in both working memory and reading comprehension.
• Experiment II revealed age-related declines in reading rate but not comprehension for the syntax task.
• Working memory limitations were linked to difficulties in processing complex syntax.

Conclusions:

• Working memory deficits in older adults impair their ability to process complex syntactic structures.
• These limitations can lead to reduced reading comprehension in timed settings and slower reading rates in untimed settings.
• The findings underscore the critical role of working memory in navigating linguistic complexity, especially in aging populations.
