Cognitive and metacognitive components of learning: Search for the locus of retarded perfomance

The introduction to this article gives a short overview of the main theoretical ideas which have been advanced to explain the low cognitive perfomances of retarded persons in learning and problem solving. The question of how retarded learners organize and control their problem solving activities led the authors to conduct a series of single case studies investigating qualitative and dynamic aspects of retarded learning. Metacognitive training research, socio-cognitive theories and a schema-theoretical top-down/bottom-up model of information processing constitute the theoretical background. In a tutorial setting mentally retarded and learning disabled subjects were presented tasks which consist of connecting amorphous clouds of dots in order to reproduce geometrical model figures. Verbal and behavioral data were collected to precisely describe the subjects problem solving activities. Post-hoc a two-dimensional category system listing 28 different problem solving components was developed. The first dimension introduces a distinction between explorative, elaborative, planning and control components, the second dimension specifies whether the components are initiated topdown or bottom-up. This category system is presented in detail followed by a few examples of analyzed problem solving sequences. Finally, the proposed model and inherent methodological problems are discussed.
