Title: The neural and behavioral control of automaticity: individual differences and the neural bases of surmounting Pavlovian learning bias
Abstract:
Pre-programmed Pavlovian responses such as approach towards, and withdrawal from, biologically significant outcomes and predictors of those outcomes afford animals useful short cuts for behavior. However, further organized layers of behavioral control on top of such biases are necessary when such Pavlovian biases conflict with longer-term instrumental goals. The prefrontal cortex (PFC) is believed to play a pivotal role in controlling Pavlovian biases, but details of its involvement remain to be shown. Using a well-established Go/NoGo task, a large sample size, model-based fMRI and functional connectivity analyses, we characterize individual differences in the capacity to overcome Pavlovian biases. Our results suggest that top-down control signals arising from PFC-temporal lobe interactions enhance instrumental over Pavlovian control.
