The aim of this workpackage is to find evidence for Darwinian neurodynamics at two different spatial scales, that of adaptation at the neuronal level, and that of adaptation at the human problem solving level. It is a strength of
the NRH that it strives towards a model that can integrate the neuronal and the behavioural levels in a single efficient framework. As before, this workpackage contains two intended complementary empirical viewpoints.
Can Replication of Synaptic Connectivity Information be demonstrated in Neuronal Culture? The aim of these experiments is two-fold: 1. to force a refinement and sanity check on the models developed in task 1.5 and of models published elsewhere that proposed mechanisms of neuronal replication, and 2. to explore what kinds of neuronal substrate may be capable of autocatalytic growth that have not been thought of in the models already.

• Show how the causal-temporal relationship between two neurons can be copied to another pair of neurons
• Show how the causal-temporal relationship between three neurons can be copied to another group of three
• Fit human performance in a range of insight problem solving tasks using the cognitive architecture developed, in comparison to rational-process models.
• Using experiments that force a change in representation (re-structuring), determine how rapidly a human subject can change hypotheses.

2.1. Demonstrate replication of causal-temporal structure between two- and three-neuron groups
2.2. Fitting human insight problem solving using the Darwinian Cognitive Architecture
2.3. Traditional Human insight problem solving experiments to infer the underlying representation of predictors/hypotheses/generative models
