A Neural Network Model of Incubation through Mind Wandering

Kasumi Nishi, Osamu Araki, Tomokazu Urakawa
2019 Australian Journal of Intelligent Information Processing Systems  
To clarify the mechanism of incubation, we constructed a neural network model including DMN that improves task performance of associative memory after MW.  ...  Although the incubation effect in memory retrieval through mind wandering (MW) is thought to be an interesting side effect, the mechanism that produces the effect remains to be elucidated.  ...  A Neural Network Model Neuron Model To realize neural dynamics in a simple manner, we adopted the Izhikevich neuron model [12] .  ...

Creativity—the unconscious foundations of the incubation period

Simone M. Ritter, Ap Dijksterhuis
2014 Frontiers in Human Neuroscience  
First, an overview of the domain of incubation and creativity is provided by reviewing and discussing studies on incubation, mind-wandering, and sleep.  ...  Creativity is one of the most important assets we have to navigate through the fast changing world of the 21st century.  ...  One candidate neural mechanism for mind-wandering is a network of regions in the frontal and parietal cortex known as the default mode network (Mason et al., 2007; Christoff et al., 2009 ).  ...

Mind the gap: an attempt to bridge computational and neuroscientific approaches to study creativity

Geraint A. Wiggins, Joydeep Bhattacharya
2014 Frontiers in Human Neuroscience  
Next we propose a neurocognitive architecture of creativity with a strong focus on various facets (i.e., unconscious thought theory, mind wandering, spontaneous brain states) of un/pre-conscious brain  ...  Recently, there has been an increasing interest in revealing the neural correlates of human creativity.  ...  Mind wandering is also assumed to be linked to the periods of incubation and insight of the creative process.  ...

Bridging the communication and cultural gap between the cognitive sciences and the contemplative traditions

Patricia E. Sharp
2013 Religion, Brain & Behavior  
Most of these practices involve "stilling the mind," whereby all content-laden thought (e.g., fantasies, daydreams, plans) ceases, and the mind enters a state of openness, formlessness, clarity, and bliss  ...  This can be explained by the Buddhist suggestion that almost all of our everyday thoughts are a form of addiction.  ...  The proposed mechanism will take the form of a neural network model that incorporates the idea of reward prediction error, as exemplified by traditional learning theory (see Rescorla & Wagner, 1972)  ...

The neurocognitive consequences of the wandering mind: a mechanistic account of sensory-motor decoupling

Julia W. Y. Kam, Todd C. Handy
2013 Frontiers in Psychology  
We then consider sensory-motor attenuation in a class of clinical neurocognitive disorders that have ties to pathological patterns of decoupling, reviews suggesting that mind wandering and these clinical  ...  A unique human characteristic is our ability to mind wander - a state in which we are free to engage in thoughts that are not directly tied to sensations and perceptions from our immediate physical environment  ...  One issue of mind wandering concerns the neural network implicated in the occurrence of decoupled thoughts.  ...

How sustainable are different levels of consciousness? [article]

Erik J Wiersma
2017 arXiv   pre-print
The human brain processes a wide variety of inputs and does so either consciously or subconsciously.  ...  This theoretical paper aims to expand on some of the aspects of the Global Workspace theory: how the properties of incoming information result in it being processed subconsciously or consciously; why processing  ...  It was found (Smallwood, McSpadden & Schooler, 2007 ) that mind wandering with awareness leads to longer response time of an unrelated task than does mind wandering without awareness.  ...

Dreaming as mind wandering: evidence from functional neuroimaging and first-person content reports

Kieran C. R. Fox, Savannah Nijeboer, Elizaveta Solomonova, G. William Domhoff, Kalina Christoff
2013 Frontiers in Human Neuroscience  
Isolated reports have long suggested a similarity in content and thought processes across mind wandering (MW) during waking, and dream mentation during sleep.  ...  To relate first-person reports to neural evidence, we compared meta-analytic data from numerous functional neuroimaging (PET, fMRI) studies of the default mode network (DMN, with high chances of MW) and  ...  Keith Lohse for a careful reading of, and conscientious comments upon, the manuscript.
