Demands and Capacities Model

• model

This model states that stuttering is likely to occur when demands for fluent and continuous speech exceed the child's capacities to perform at a level required by these demands. Factors that affect fluent speech include (1) motor coordination, (2) linguistic ability, (3) social and emotional functioning, and (4) cognitive development. Clinically, attempts are made to reduce demands placed upon the child and increase the child's capacities for dealing with them.
