Mechanisms of Semantic Composition in Older and Younger Adults

Supplementary file 1_Mechanisms of semantic composition in older adults: control, semantic processing, and imagery.docx is a 42.1 KB document authored by Heather Bruett and last updated on May 14, 2026. It describes a study involving 87 healthy older adults and 83 younger adults who completed a semantic composition task and cognitive assessments.

Use Cases

• Analyze the relationship between cognitive control and semantic composition based on the described task performance.
• Investigate the role of visual imagery in attributive conceptual combinations based on the study's findings.
• Compare cognitive mechanisms underlying semantic composition between older and younger adult cohorts.
• Study individual differences in semantic processing, divergent/convergent thinking, and imagery as predictors of conceptual flexibility.

Strengths

• The dataset description provides specific participant counts: 87 older adults and 83 younger adults.
• The study design includes multiple cognitive assessments: semantic processing, cognitive control, creative thinking, and visual imagery.
• The license is clearly stated as CC-BY-4.0, allowing for open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data file is a 42.1 KB DOCX document, suggesting a limited scope focused on textual analysis or supplementary materials rather than a primary dataset.
