About this Research Topic
Complex systems are to be seen as typically having multiple levels of organization. For instance, in the behavioural and cognitive sciences, there has been a long lasting trend, promoted by the seminal work of David Marr, putting focus on three distinct levels of analysis: the computational level, accounting for the What and Why issues, the algorithmic and the implementational levels specifying the How problem.
However, the tremendous developments in neuroscience knowledge about processes at different scales of organization together with the complexity of today cognitive theories suggest that there will hardly be only three levels of explanation. Instead, there will be many different degrees of commitments corresponding to the different granularities—from high-level (behavioural) models to low-level (neural and molecular) models of the cognitive research program. For instance, Bayesian approaches, that are usually advocated for formalizing Marr's computational level and rational behaviour, have even been adopted to model synaptic plasticity and axon guidance by molecular gradients. As a result, we can consider the behavioural scientist as dealing with models at a multiplicity of levels.
The purpose of this Research Topic in Frontiers in Theoretical and Philosophical Psychology is to promote an approach to the role of the levels and explanation and models which is of interest for cognitive scientists, neuroscientists, psychologists, behavioural scientists, and philosophers of science.
We solicit original empirical work, review and opinion papers, and methodological and epistemological papers that can provide both state-of-the-art views and advancement proposals for our understanding of the proposed topic. The following are potential issues: How can the autonomy of explanatory levels be properly understood in behavioural explanation? Is reductionism a satisfactory strategy? If so, how can it be justified? How can high-level and low-level models be constrained in order to be actually explanatory of both behavioural and neurological or molecular evidence? What is the kind of relationship between those models? What is the actual contribution to explanation provided by Bayesian modelling?
