How do animals weigh conflicting information about reward sources over time? Comparing dynamic averaging models
Anim Cogn. 2024 Mar 2;27(1):11. doi: 10.1007/s10071-024-01840-2.ABSTRACTOptimal foraging theory suggests that animals make decisions which maximize their food intake per unit time when foraging, but the mechanisms animals use to track the value of behavioral alternatives and choose between them remain unclear. Several models for how animals integrate past experience have been suggested. However, these models make differential predictions for the occurrence of spontaneous recovery of choice: a behavioral phenomenon in which a hiatus from the experimental environment results in animals reverting to a behavioral allocation co...

Choosing the best way: how wild common marmosets travel to efficiently exploit resources
Anim Cogn. 2024 Mar 2;27(1):20. doi: 10.1007/s10071-024-01864-8.ABSTRACTWhile foraging, animals have to find potential food sites, remember these sites, and plan the best navigation route. To deal with problems associated with foraging for multiple and patchy resources, primates may employ heuristic strategies to improve foraging success. Until now, no study has attempted to investigate experimentally the use of such strategies by a primate in a context involving foraging in large-scale space. Thus, we carried out an experimental field study that aimed to test if wild common marmosets (Callithrix jacchus) employ heuristic ...

Bolder together: conformity drives behavioral plasticity in eastern gartersnakes
Anim Cogn. 2024 Feb 22;27(1):2. doi: 10.1007/s10071-024-01859-5.ABSTRACTPersonality traits drive individual differences in behaviour that are consistent across time and context. Personality limits behavioural plasticity, which could lead to maladaptive choices if animals cannot adapt their behavior to changing conditions. Here, we assessed consistency and flexibility in one personality trait, boldness, across non-social and social contexts in eastern gartersnakes (Thamnophis sirtalis sirtalis). Snakes explored a novel open arena either alone or in a pair. Pairs were assigned based on the data from the solo trials, such tha...

Available and unavailable decoys in capuchin monkeys (Sapajus spp.) decision-making
Anim Cogn. 2024 Feb 23;27(1):3. doi: 10.1007/s10071-024-01860-y.ABSTRACTDecision-making has been observed to be systematically affected by decoys, i.e., options that should be irrelevant, either because unavailable or because manifestly inferior to other alternatives, and yet shift preferences towards their target. Decoy effects have been extensively studied both in humans and in several other species; however, evidence in non-human primates remains scant and inconclusive. To address this gap, this study investigates how choices in capuchin monkeys (Sapajus spp.) are affected by different types of decoys: asymmetrically do...
