Cognitive procedural learning among children and adolescents with or without spastic cerebral palsy: the differential effect of age.

The team asked two groups of kids to play a computer game. One group had spastic cerebral palsy. The other group had typical development.

The game was a probabilistic classification task. Kids had to guess which picture would win based on hidden odds. The researchers tracked how learning speed changed with age.

Both groups got better at the game, but in different ways. Typical kids improved faster as they got older. Kids with CP showed the same learning speed whether they were eight or eighteen.

In other words, maturation alone did not help the CP group catch up.

Janssen et al. (2011) saw the same flat age curve in motor planning. Kids with CP did not show the age-related grasp-height gains that typical kids did. The pattern now shows up in both motor and cognitive tasks.

Cavézian et al. (2010) gives hope. Eight weeks of constraint-induced movement therapy plus bimanual training improved planning in preschoolers with CP. The new study agrees: waiting for older age will not close the gap; active training is needed.

de Freitas Feldberg et al. (2021) widens the lens. They found medium-sized deficits in number sense and working memory across the same CP population. Together, the papers paint a clear picture: core learning systems in CP need targeted support, not just extra time.

If you work with school-age clients who have CP, do not assume they will “grow into” complex tasks. Add structured practice with clear feedback instead of simply repeating the activity. Use varied trial orders, as Prado et al. (2017) showed random practice boosts motor retention in CP. Track progress weekly; if the curve is flat, adjust cues or break the skill into smaller steps.
