In general, children with a range of special needs have below-average motiv
ation and perceived control. We have investigated whether differences exist
between the types of problem in different special groups. Theory distingui
shes between two types: low motivation and perceived control can be based e
ither on a low perceived contingency, or on a low perceived competence. The
se two types of problem require different intervention strategies. The deve
lopment of these types is related to several factors that might vary system
atically in different special groups: specific histories of experience of s
uccess and failure, the possibilities of perceiving contingencies, and the
kind of feedback and attributions from important others. We asked teachers
to rate their pupils and found, in accord with our expectations, that child
ren with social, emotional and behavioural problems, children with moderate
learning difficulties and children with specific learning difficulties hav
e more problems in perceived competence than children with physical or visu
al impairments. There was a non-significant tendency in the expected direct
ion for children with physical impairments to have lower perceived continge
ncy scores than the other groups. We conclude that caution is required in g
eneralizing research findings from one special group to another, and in the
application of intervention techniques that have been developed for one pa
rticular group.
