Language
One person thinks in a running verbal narration, talks themselves through every task, and processes best by writing it out. Another has little or no inner monologue at all and plans in images, spatial arrangement, and felt sequence. Both assume their inner experience is the universal one. Neither is right.
Language covers the work language does inside the mind rather than its role as a social skill. It maps how verbal inner speech scaffolds self-regulation and planning, how efficiently the sound layer supports reading and verbal sequencing, how fast words surface when needed, how automatically implied meaning is decoded, and whether thought itself occurs in verbal or non-verbal form. These differences shape work, learning, and communication.
