Between Interface and Truth: Multi-Task Selection Drives Ecologically Veridical Perception
Published: 2026-03-05
Subjects: Applied Mathematics, Biostatistics, Cognitive Neuroscience, Evolution
When does optimisation for performance yield representations that track world structure? We develop a mathematical theory of agents with a single fixed encoding shared across tasks, and use it to resolve the broader debate over whether selection favors fitness-tuned interfaces or veridical perception. Selection favors ecological veridicality: preserving exactly those world-state distinctions [...]
The trade-off between vocal learning and dexterity: a balancing act

Uncontroversial evidence of vocal production learning, the capacity to modify vocal output on the basis of experience, is sparsely distributed in the animal kingdom. We suggest that this is in large part due to a trade-off between vocal learning complexity and a much more widely distributed trait—non-vocal dexterity. We argue that given some generally required neural and anatomical conditions for [...]
Experimental mosaic brain evolution improves main executive function abilities in the guppy
Published: 2022-09-21
Subjects: Behavioral Neurobiology, Cognitive Neuroscience, Life Sciences, Neuroscience and Neurobiology
Executive functions are a set of cognitive control processes required for optimizing goal- directed behaviour. Despite more than two centuries of research on executive functions, both in humans and nonhuman animal species, there is still a knowledge gap of what constitutes the mechanistic basis of evolutionary variation in executive function abilities. Here we show experimentally that changes in [...]
