A comparative study of mastery motivation in young children with Down's syndrome: similar outcomes, different processes?
The main conclusion was that children with DS in the MA range of 24-36 months do not differ in their persistence with challenging tasks when compared with typically developing children of the same MA. The implication is that motivational development is delayed for children with DS, rather than deficient. However, there were some indications of possible differences in the processes underlying mastery behaviour in the two groups. The study addresses a number of conceptual and methodological issues associated with mastery motivation research, and stresses the important contribution that future longitudinal studies could make.
By comprehensive genomic comparisons, we identified protein families specific to the human typhoidal serovars, which will greatly facilitate investigations on typhoid pathogenesis.
