Object Permanence & ADHD: “Out Of Sight, Out of Mind”

People with ADHD do not lack object permanence in this literal, developmental sense. Instead, “object permanence” in ADHD is a metaphor used by individuals to describe their difficulties remembering or staying aware of things that aren’t currently visible or present.

ADHD & Time Blindness

Time blindness refers to a consistent difficulty sensing, tracking, and estimating time. It’s as if the internal clock many people rely on runs differently—or barely runs at all. For someone with ADHD, minutes can feel like seconds or stretch into hours. This disconnect makes it incredibly hard to plan, prioritize, and transition between tasks.
