We consider a behavioural model of an animal choosing between two activities, based on positive feedback, and examine
the effect of introducing cross inhibition between the motivations for the two activities. While cross-inhibition has previously
been included in models of decision making, the question of what benefit it may provide to an animal’s activity selection
behaviour has not previously been studied. In neuroscience and in collective behaviour cross-inhibition, and other equivalent
means of coupling evidence-accumulating pathways, have been shown to approximate statistically-optimal decision-making and
to adaptively break deadlock, thereby improving decision performance. Switching between activities is an ongoing decision
process yet here we also find that cross-inhibition robustly improves its efficiency, by reducing the frequency of costly switches
between behaviours [Current Zoology 61 (2): 242–250, 2015].

Genotype determining aerobic exercise capacity associates with behavioral plasticity in middle-aged rats
Mäkinen, Elina; Wikgren, Jan; Pekkala, Satu; Koch, Lauren G.; Britton, Steven L.; Nokia, Miriam S.; Lensu, Sanna (Elsevier BV, 2023)Good aerobic fitness associates positively with cognitive performance and brain health and conversely, low aerobic fitness predisposes to neurodegenerative diseases. To study how genotype together with exercise, started ... -
Spatial Memory Drives Foraging Strategies of Wolves, but in Highly Individual Ways
Gurarie, Eliezer; Bracis, Chloe; Brilliantova, Angelina; Kojola, Ilpo; Suutarinen, Johanna; Ovaskainen, Otso; Potluri, Sriya; Fagan, William F. (Frontiers Media SA, 2022)The ability of wild animals to navigate and survive in complex and dynamic environments depends on their ability to store relevant information and place it in a spatial context. Despite the centrality of spatial memory, ... -
Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish
Sbragaglia, Valerio; Gliese, Catalina; Bierbach, David; Honsey, Andrew E.; Uusi-Heikkilä, Silva; Arlinghaus, Robert (Wiley-Blackwell Publishing Ltd., 2019)The role of sexual selection in the context of harvest‐induced evolution is poorly understood. However, elevated and trait‐selective harvesting of wild populations may change sexually selected traits, which in turn can ... -
Creating a Framework for Improving the Learnability of a Complex System
Linja-aho, Minttu (University of Jyväskylä, Agora Center, 2006)When designing complex systems, it is crucial but challenging to make them easy to learn. In this paper, a framework for improving the learnability of a complex system is presented. A classification of factors affecting ... -
