Mental Availability
Capacity changes from moment to moment.
Shrink Definition
Mental availability refers to the amount of cognitive capacity currently available for attention, learning, decision-making, creativity, and emotional regulation after accounting for existing demands on the mind. Mental availability fluctuates throughout the day depending on sleep, stress, workload, emotional state, physical health, and recovery.
