Cognitive Accessibility: Making a Spreadsheet an Accessible Tool, Not a Maze
Cognitive Accessibility: Making a Spreadsheet an Accessible Tool, Not a Maze I opened a fresh spreadsheet on a Sunday night, determined to finally get my life in order. By Tuesday, I had 14 color-coded columns, three abandoned trackers, and a quiet sense of shame. I had built another maze and called it a planner. That failure has a name in the research. This post is about what the science…
Creating an accessible tool for people with ADHD requires understanding the cognitive challenges they face. Research has shown that working memory deficits are common in ADHD, with effect sizes ranging between d=1.63 and d=2.03 (Kofler et al., 2020). This means that tools must not require users to hold complex rules in their heads, as these are difficult for those with impaired working memory.
Time perception is another significant issue for ADHD individuals. Studies have found impairments in time estimation, reproduction, and management (Mioni et al., 2023). This means that scheduling tools must make time visible and tangible, providing clear blocks of time and showing actual progress rather than abstract estimates.
Immediate rewards are essential for maintaining motivation in ADHD individuals. Delayed rewards lose value quickly, with a medium effect size of d=0.43 (Jackson & MacKillop, 2016). This means that tracking systems should provide small, frequent rewards, such as visible progress updates, to keep users engaged.
Lastly, tools for ADHD users must be low-friction and non-punitive. Emotional dysregulation is a core feature of ADHD, and tools that judge or scold users can create shame and discourage use (Faraone et al., 2019; Beheshti et al., 2023). Instead, designing tools that make it easy to return after missed days and provide immediate feedback can help create an accessible planner for those with ADHD.
