Associate learning for visual nonverbal and auditory
verbal items was examined in 21 children with spastic diplegic
cerebral palsy (SDCP) and 28 healthy children using four
paired associate tasks. SDCP children showed poorer performance
than the comparison group for learning pairs that required
visual nonverbal responses, regardless of the stimulus
modality. Within the SDCP group, lesion severity was assessed
in 17 of the children. Lesion severity was related to the
level of performance on paired associate tasks requiring
visual nonverbal responses; lesion severity did not reach
statistical significance for tasks requiring auditory verbal
responses. The study suggests: (1) periventricular white
matter regions are important for the development of basic
learning processes, such as associative learning, and (2)
learning of visual nonverbal material is disproportionately
affected following white matter injury early in life. (JINS,
