Cerebral palsy, typically diagnosed in childhood, clearly continues into adulthood. This study describes the long-term medical, functional, educational, and psychosocial outcomes of people with cerebral palsy. Of the 203 people with cerebral palsy diagnosed and treated at the Child Development Center in Tel Aviv between 1975 and 1994, 163 (80%; age range 8-30 years, mean age 18.9 years, and median age 19 years) participated in a cross-sectional telephone survey. Half the respondents have chronic health problems: 78% report they experience gross motor disability, of whom 22% are wheelchair users; 30% to 50% need help in various activities of daily living; 35% have mental retardation; 79% completed 12 years or more of schooling; 78% live with their parents; 25% have served in the army; 23% have a driver's license; and 23% work in competitive employment. The large majority is involved in varied leisure activities and report a high level of life satisfaction.

BackgroundRecent studies suggest that human auditory perception follows a prolonged developmental trajectory, sometimes continuing well into adolescence. Whereas both sensory and cognitive accounts have been proposed, the development of the ability to base current perceptual decisions on prior information, an ability that strongly benefits adult perception, has not been directly explored. Here we ask whether the auditory frequency discrimination of preschool children also improves when given the opportunity to use previously presented standard stimuli as perceptual anchors, and whether the magnitude of this anchoring effect undergoes developmental changes.Methodology/Principal FindingsFrequency discrimination was tested using two adaptive same/different protocols. In one protocol (with-reference), a repeated 1-kHz standard tone was presented repeatedly across trials. In the other (no-reference), no such repetitions occurred. Verbal memory and early reading skills were also evaluated to determine if the pattern of correlations between frequency discrimination, memory and literacy is similar to that previously reported in older children and adults. Preschool children were significantly more sensitive in the with-reference than in the no-reference condition, but the magnitude of this anchoring effect was smaller than that observed in adults. The pattern of correlations among discrimination thresholds, memory and literacy replicated previous reports in older children.Conclusions/SignificanceThe processes allowing the use of context to form perceptual anchors are already functional among preschool children, albeit to a lesser extent than in adults. Nevertheless, immature anchoring cannot fully account for the poorer frequency discrimination abilities of young children. That anchoring is present among the majority of typically developing preschool children suggests that the anchoring deficits observed among individuals with dyslexia represent a true deficit rather than a developmental delay.

Studies of monolingual narrative production have revealed interacting paths in the development of coherence and cohesion across languages but less is known about bilingual narratives, where a gap may exist between socio-cognitive and linguistic abilities. The present longitudinal study explores the relations between measures of coherence and cohesion in the picture-based oral narratives elicited from 23 sequential bilinguals at two times -2nd and 4th years of exposure to Hebrew as L2 (ages 6 and 8, respectively), compared to those produced by agematched Hebrew speaking monolinguals. Measures of coherence included reference to story components, and to four types of causal relations: psychological, motivational, enabling and physical. These analyses served as a basis to explore cohesion in terms of (1) inter-clausal connectivity, and (2) the linguistic encoding of the causal chain, which in this context demanded reference to a complex motion event. We found that reference to narrative components and causal relations improved with age in both L1 and L2, but were largely delayed among bilinguals at age 6, particularly regarding the most complex scenes. While coherence measures reached to a parallel level among the 8 year-old children, measures of cohesion showed a different path of development in L1 and L2. Thus, the constraints imposed by language use in organizing the discourse resulted in a poorer connectivity between the clauses, and in less accurate lexico-grammatical encoding of the events in the bilingual narratives. The study underscores the mutual attraction between local and global principles of narrative construction, Requests for further information should be directed to Judy R.
