Frontal network dynamics reflect neurocomputational mechanisms for reducing maladaptive biases in motivated action

Jennifer C Swart, Michael J Frank, Jessica I Määttä, Ole Jensen, Roshan Cools, Hanneke E M den Ouden
2018 PLoS Biology  
Midfrontal theta-band (4 Hz-8 Hz) activity covaried with the level of Pavlovian conflict and was associated with reduced Pavlovian biases rather than reduced instrumental learning biases.  ...  This work links midfrontal processing to detecting Pavlovian conflict and highlights the importance of network processing in reducing the impact of maladaptive, Pavlovian biases.  ...  In the following, we disentangle the contribution of these cue-based Pavlovian response biases and outcome-based instrumental learning biases to the observed motivational bias in Go responding before turning  ...

Catecholaminergic challenge uncovers distinct Pavlovian and instrumental mechanisms of motivated (in)action

Jennifer C Swart, Monja I Froböse, Jennifer L Cook, Dirk EM Geurts, Michael J Frank, Roshan Cools, Hanneke EM den Ouden
2017 eLife  
We present a novel paradigm, allowing us to disentangle the impact of reward and punishment on instrumental learning from Pavlovian response biasing.  ...  Computational analyses showed that motivational biases reflect both Pavlovian and instrumental effects: reward and punishment cues promoted generalized (in)action in a Pavlovian manner, whereas outcomes  ...  Acknowledgements We thank Monique Timmer and Peter Mulders for medical assistance; Dr. Sean James Fallon for advice on setting up the MPH study; Dr. Matthew Albrecht for help with RStan.  ...

Motivational sensitivity of outcome-response priming: Experimental research and theoretical models

Poppy Watson, Reinout W. Wiers, Bernhard Hommel, Sanne de Wit
2018 Psychonomic Bulletin & Review  
This is a simple and parsimonious mechanism by which activation of outcome representations (e.g. thinking about the light coming on) leads to activation of the associated motor patterns required to achieve  ...  While there is a wealth of evidence that both the perceptual and motivational properties of an outcome can be encoded in the O-R association and mediate O-R priming, we critically examine the integration  ...  A number of studies have systematically investigated how Pavlovian stimuli facilitate and inhibit approach and avoidance actions, revealing a complex interaction between Pavlovian outcome valence, instrumental  ...

Go and no-go learning in reward and punishment: Interactions between affect and effect

Marc Guitart-Masip, Quentin J.M. Huys, Lluis Fuentemilla, Peter Dayan, Emrah Duzel, Raymond J. Dolan
2012 NeuroImage  
We studied the acquisition of instrumental responding in healthy human volunteers in a task in which we orthogonalized action requirements and outcome valence.  ...  Using computational reinforcement-learning models, we teased apart contributions from putatively instrumental and Pavlovian components in the generation of the observed asymmetry during learning.  ...  Pavlovian responses associated with predictions of reward usually entail vigorous active approach and engagement (Gray and McNaughton, 2000) , irrespective of the instrumental validity of these actions  ...

Individual differences in bodily freezing predict emotional biases in decision making

Verena Ly, Quentin J. M. Huys, John F. Stins, Karin Roelofs, Roshan Cools
2014 Frontiers in Behavioral Neuroscience  
Furthermore, our findings help bridge (animal and human) decision making and emotion research to advance our mechanistic understanding of decision making anomalies in daily encounters as well as in a wide  ...  Our data evidence an emotional biasing of instrumental action. Thus, angry relative to happy faces slowed instrumental approach relative to avoidance responses.  ...  These findings speak to a traditional debate in the Pavlovian-to-instrumental transfer literature (Lovibond, 1983) about the role of Pavlovian influences, and support the idea that Pavlovian stimuli  ...

Overcoming Pavlovian bias in semantic space

Sam Ereira, Marine Pujol, Marc Guitart-Masip, Raymond J. Dolan, Zeb Kurth-Nelson
2021 Scientific Reports  
AbstractAction is invigorated in the presence of reward-predicting stimuli and inhibited in the presence of punishment-predicting stimuli.  ...  However, we demonstrate that when subjects engage in instrumental learning in a verbal semantic space, as opposed to a motoric space, not only do they exhibit the typical Pavlovian bias, but this Pavlovian  ...  The Wellcome Centre for Human Neuroimaging is supported by core funding from the Wellcome Trust  ...

Reward and avoidance learning in the context of aversive environments and possible implications for depressive symptoms

Miriam Sebold, M. Garbusow, P. Jetzschmann, D. J. Schad, S. Nebe, F. Schlagenhauf, A. Heinz, M. Rapp, N. Romanczuk-Seiferth
2019 Psychopharmacology  
We discuss our findings in the light of the involvement of the neuromodulators serotonin and dopamine.  ...  Aversive stimuli in the environment influence human actions. This includes valence-dependent influences on action selection, e.g., increased avoidance but decreased approach behavior.  ...  So far, previous studies investigating valence-action interactions have realized actions along an axis of activation, thus as approach/avoidance or go/no-go responses.  ...
