Graph Mapping

Graph Mapping assesses fluid intelligence by requiring participants to map corresponding nodes between two mathematically isomorphic but visually distinct graphs.

Key Features:

• Flexibility in Item Generation: Difficulty levels can be adjusted from trivial to extremely challenging to create progressive item sequences for correlational studies.
• Adaptability for Experimental Designs: Supports multiple item instances at a fixed difficulty level and full item randomization to accommodate within-subject, longitudinal, and adaptive testing designs.
• Psychometric Properties: Exhibits convergent validity and reliability comparable to three leading traditional fluid reasoning tests.
• Minimized Practice Effects: The unfamiliar test format reduces prior exposure and practice effects, enhancing measurement validity.
• Short Administration Time: Short administration time reduces participant fatigue in research settings.
• Customizable Software: Accompanying software enables researchers to design test variants tailored to specific studies and sample populations.

Scientific Applications:

• Psychological and cognitive neuroscience research: Assessment of fluid intelligence and reasoning processes across experimental and clinical studies.
• Developmental studies: Investigation of developmental changes in reasoning abilities across age groups.
• Intervention evaluation: Examination of the impact of cognitive or educational interventions on fluid intelligence.
• Individual differences research: Exploration of variability in problem-solving skills and reasoning across individuals.
• Longitudinal studies: Within-subject tracking of changes in fluid intelligence over time.
