Intermediate learning step: influence on adaptation pathways. The threshold between relational and representational adaptation (\(\bar{\alpha }\)) is modulated by the magnitude of an intermediate step \(\beta\). (a) The fraction of networks that adapt \(\theta\) for training with an intermediate step \(\alpha \rightarrow \beta \rightarrow -\alpha\) for various pairs of \((\alpha ,\beta )\). (b) Large values of \(|\beta |\) lower \(\bar{\alpha }\), promoting representational adaptation, while small \(|\beta |\) increases \(\bar{\alpha }\), favoring relational adaptation. The gray dashed line represents \(\bar{\alpha }\) in the absence of an intermediate step, highlighting how structured transitions can shape the adaptation process.
