Abstract
I propose a cautionary assessment of the recent debate concerning the impact of the dynamical approach on philosophical accounts of scientific explanation in the cognitive sciences and, particularly, the cognitive neurosciences. I criticize the dominant mechanistic philosophy of explanation, pointing out a number of its negative consequences: In particular, that it doesn’t do justice to the field’s diversity and stage of development, and that it fosters misguided interpretations of dynamical models’ contribution. In order to support these arguments, I analyze a case study in computational neuroethology and show why it should not be understood through a mechanistic lens; I specially focus on Zednik’s mechanistic interpretation of the case study. In addition, I argue for a greater appreciation of the relation between explanation and other epistemic goals in the field, as well as an increased sensitivity towards the associated contextual factors.

Notes
However, in the case of Zednik, this does not imply that there is no space for non-mechanistic dynamical explanation in cognitive science, as is shown by his analysis of Haken, Kelso and Bunz’s model of bimanual coordination as a covering law explanation –despite his comments on the known philosophical problems of this view on explanation (cf., Zednik 2011: 245–246). As we will see, my criticism towards Zednik lies specifically in what I see as an inadequate rendering of dynamical models’ rationale and contribution to the field.
It is worth mentioning that I do not endorse the position Revonsuo (2001: 57–58) presents regarding dynamicism, which he sees as a recent version of functionalism in cognitive science; however, I highlight his warning on the importance of directing our reflections to more defined scientific fields.
It is interesting to note how Bickle (2006) appeals to what he sees as an unfitting assessment of neuroscience's state of the art (in this case, molecular and cellular neuroscience) facing cognitive phenomena, as part of the motives behind the poor adherence to his radical reductionism in philosophy of neuroscience. Clearly, selecting the neuroscientific area that is object of philosophical reflection and subsequent evaluation has a major impact on the epistemological conclusions finally obtained.
Although other aspects can be highlighted: For example, in a philosophical take on this same model by Beer, Chemero (cf., 2009: 38) highlights its predictive benefits and its ability to support counterfactuals.
Similar considerations to the ones I developed in Beer’s case also apply to Zednik’s interpretation of the A-not-B error model by Thelen and collaborators. Again, I don’t see why the contribution here must be strictly understood in terms of functional decomposition of a complex task into low-level (perceptual and motor) activities. Analyzing this case exceeds my purposes here.
In line with my remarks, I would agree with rejecting the dichotomy framed in this way, but my proposal is very different from the authors’.
