Time Blindness in ADHD

Plain-language summary

Research suggests that people with ADHD often experience time differently than those without the condition. This can manifest as a non-linear, present-focused perception of time, diverging from typical expectations. While some studies explore the underlying mechanisms of attention, direct evidence specifically linking these to ADHD time perception is still developing and sometimes mixed.

Key findings

• People with ADHD may experience "time blindness," where they struggle to accurately judge the passage of time.
• The "now/not now dichotomy" suggests that individuals with ADHD often perceive time as either the immediate present or the distant unreality, without much in-between.
• Hyperfocus, a state of intense concentration, can significantly alter the perception of time, making hours feel like minutes.
• The experience of being in "waiting mode" can also distort time perception for individuals with ADHD, making waits feel much longer or shorter than they truly are.

   This article examines the lived experiences of ADHDers with respect to time perception, through the lens of a neuroqueer temporality framework and its representation in graphic medicine. By close-reading autobiographical comics digitally posted by Pina Varnel (ADHD Alien), Dani Donovan, Heidi Burton, and Cecil, the article studies key elements of ADHD time perception, including time blindness, the now/not now dichotomy, the waiting mode, and the state of hyperfocus. ADHDers' perception of time is nonlinear and present-oriented, diverging from neuronormative temporal expectations. In visualizin
