Description¶

The review outlines future research directions: developing and evaluating diagnostic marker tasks to identify DD in adults, and using neurostimulation techniques such as TMS to manipulate brain activity as an independent variable to investigate causal contributions of activated areas to task performance. It further recommends longitudinal and cross-sectional group and single-case studies grounded in sound conceptual knowledge and current psychometric standards, plus structural and functional connectivity studies to identify fiber tracts involved in residual and deficient neurocognitive processes.

Design Implications¶

Context¶

Requirements¶

• Requires studies grounded on sound conceptual knowledge and conducted according to current scientific psychometric standards

Constraints¶

• Research on adults captures the final stage of the disorder, so observed behaviors and neural substrates may reflect lifelong compensatory strategies rather than the disorder itself

Target Learners¶

• adults with developmental dyscalculia

Target Learning Goals¶

• identification and diagnosis of DD in adults
• understanding neurocognitive underpinnings of persistent numeracy difficulties

Related Strategies¶

• Interventions for adult DD should target both number-specific core deficiencies and domain-general skills while incorporating preserved skills
