Age-Related Differences in Perceptual and Mental Imagery Abilities

Supplementary data from a 2026 study by Anna Maria Berardi investigating age-related differences in visual processing. The dataset includes results from the Imagery Processing Battery (IPB), comprising 15 tasks assessing dorsal and ventral pathway functions. It contains correlation matrices, response times, and error rates for young and elderly participants.

Use Cases

• Analyze correlation matrices between 15 perceptual tasks to study dorsal and ventral pathway interactions.
• Compare response times and error rates between young and elderly groups across dorsal and ventral imagery conditions.
• Apply nonmetric multidimensional scaling (MDS) on task correlation data to visualize cluster separation for different age groups.
• Test the generalized slowing hypothesis using logarithmic response times provided in the dataset.
• Model age-related changes in spatial (dorsal) versus object (ventral) processing accuracy from the IPB task results.

Strengths

• Data is derived from a structured experimental battery (IPB) with 15 specific tasks.
• Includes comparative metrics for two distinct age groups (young and elderly).
• Correlation matrices are provided for both perception and imagery conditions.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset scope is limited, with a file size of only 261.4 KB, suggesting a small sample size or aggregated results.
• Raw individual participant data or row counts are not specified, limiting granular analysis.
• Geographic and demographic specifics of the participant pool are unknown, which may affect generalizability.
