The perturbation paradigm modulates error-based learning in a highly automated task: outcomes in swallowing kinematics

C. Anderson, P. Macrae, I. Taylor-Kamara, S. Serel, A. Vose, I. A. Humbert
2015 Journal of applied physiology  
Systematic-error reduction occurred only during the abrupt-masked and abrupt-unmasked perturbations. Only the abrupt-masked perturbation caused aftereffects.  ...  The four study conditions were gradual-masked, gradual-unmasked, abrupt-masked, and abrupt-unmasked.  ...  Thus we compared masked and unmasked onset and offset of both gradual and abrupt perturbations. We hypothesized that, consistent with Humbert et al.  ...

No language unification without neural feedback: How awareness affects sentence processing

2019 NeuroImage  
In the masked condition we only found an N400 effect for single words, whereas in the unmasked condition we observed an N400 effect for both unmasked sentences and single words.  ...  According to the Memory, Unification and Control (MUC) model, sentence processing requires long-range feedback from the left inferior frontal cortex (LIFC) to left posterior temporal cortex (LPTC).  ...  Acknowledgements We thank Camilla Endrizzi for her valuable assistance with data acquisition of Experiment 2.  ...
