Abstract:Context-dependant learning refers to the phenomenon that there is better performance on a task when the environmental context that is present during learning matches the context that is present during testing. The present study examined whether contextual dependencies, which have been found in motor movements, can also be found in the preparation phase of these movements. Furthermore a possible mediator role of task difficulty and practice was examined. Therefore two context manipulations (switched and novel), two sequence lengths (three-key and six-key) and two practice groups (limited and extended practice) were included. The results demonstrated contextual dependencies for the shorter threekey sequence in both context manipulations. However, these results were not confirmed for the six-key sequence because no effects of context manipulation have been found for this sequence length. A possible explanation for these findings is that context manipulation prevented full sequence preparation for the three-key sequence due to insufficient time for the cognitive processor to prepare the sequence – this was not the case for the longer sequence as time to prepare and identify the sequence was remarkably longer than for the shorter sequence. Furthermore no differences in the development of contextual dependencies between practice groups have been found indicating that the amount of practice does not mediate the development of contextual dependencies for three-key sequences in motor-preparation tasks.
