A central capacity sharing model of dual-task performance.
@article{Tombu2003ACC, title={A central capacity sharing model of dual-task performance.}, author={M. Tombu and P. Jolicoeur}, journal={Journal of experimental psychology. Human perception and performance}, year={2003}, volume={29 1}, pages={ 3-18 } }
The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus onset asynchronies (SOAs), underadditivity of precentral Task 2 manipulations, additivity of central or… Expand
