Assembling Old Tricks for New Tasks: A Neural Model of Instructional Learning and Control

Tsung-Ren Huang, Thomas E. Hazy, Seth A. Herd, Randall C. O'Reilly
2013 Journal of Cognitive Neuroscience  
On the basis of data from neuroanatomy, neurophysiology, and neuroimaging, a biologically plausible model is developed to illustrate the neural mechanisms of learning from instructions.  ...  The slow-learning parietal pathway carries out simple or habitual stimulus-response (S-R) mappings, whereas the fast-learning hippocampal pathway implements novel S-R rules.  ...  The views and conclusions contained herein are those of the authors and should not be interpreted as necessarily representing the official policies or endorsements, either expressed or implied, of IARPA  ...

Neural Coding for Instruction-Based Task Sets in Human Frontoparietal and Visual Cortex

Paul S. Muhle-Karbe, John Duncan, Wouter De Baene, Daniel J. Mitchell, Marcel Brass
2016 Cerebral Cortex  
We devised a paradigm requiring either implementation or memorization of novel stimulus-response mapping instructions, and used multivoxel pattern analysis of neuroimaging data to compare neural coding  ...  Task preparation has traditionally been thought to rely upon persistent representations of instructions that permit their execution after delays.  ...  The authors would like to thank Maggie Lynn and Jan Derrfuss for helpful discussion, and two anonymous reviewers for thoughtful comments on an earlier version of the manuscript.  ...

The functional role of working memory in the (re-)planning and execution of grasping movements

M. A. Spiegel, D. Koester, T. Schack
2013 Journal of Experimental Psychology: Human Perception and Performance  
Participants initially planned a placing movement toward 1 of 2 targets, subsequently encoded verbal or spatial information in WM, and then executed the movement during the retention phase.  ...  Hence, the results of Experiments 1 and 2 demonstrate that executing a prepared movement recruits domain-specific visuospatial memory resources.  ...  By comparing performance in a prepared condition (keep the prepared action plan) with performance in a replanned condition (implementation of new action plan required) in verbal and spatial WM tasks, we  ...
