A new study found that robot-delivered feedback can help learners recover from mistakes, but more personalized feedback was not automatically more helpful in the next moment. Personalized feedback was linked to better overall performance across the whole task, suggesting a trade-off between detailed feedback and learning speed.
Researchers found that bird predators adjust their attacks to avoid triggering strong collective waves from sulphur mollies, but also exploit weak points in the group's defense. The fish, in turn, seem to 'remember' previous predator attacks, leading to stronger responses when attacked again.
Researchers used afterimages to measure brain predictions of visual consequences of eye movements, finding that predictions are accurate but subject to systematic errors. The brain's efference copy helps predict visual shifts, but this prediction falls short of the actual eye movement's consequences.
Collective animal behavior research is entering a new interdisciplinary phase, driven by AI, sensing technologies, and virtual reality. This transformation enables scientists to track and analyze whole groups in unprecedented detail, capturing patterns previously invisible. Insights from animal swarms are increasingly shaping real-worl...
Researchers created a large-scale mouse behavior dataset to study complex behaviors like problem-solving and goal-directed actions. The dataset, featuring over 100 hours of footage and detailed human annotations, provides a benchmark for developing algorithms that analyze animal cognition.
Researchers found that larger fish shoals become more accurate and faster at detecting real threats and distinguishing them from harmless disturbances. The findings suggest that large animal collectives can overcome trade-offs between speed and accuracy, and may operate under a state of criticality, optimizing information flow.
A study published in Nature Communications reveals that the speed of saccadic eye movements predicts the speed limit in vision when an object becomes too fast to see. People with faster saccadic eye movements can perceive faster-moving objects better than those with slower ones.
Researchers used Minecraft to investigate how humans dynamically integrate asocial and social information in realistic contexts. The study found that adaptability is the most important driver of success, and that flexible switching between individual and social learning strategies amplifies human intelligence.
Researchers discovered that individual prey follows simple decision-making rules, leading to complex collective escape patterns. The 'fountain effect' allows sardines to outmaneuver marlins, but predators can also exploit this defense mechanism by attacking from the side or back.
A study found that people's eyes are drawn to areas with high potential for change before any movement occurs, even when the scene appears static. This behavior is not limited to animate objects and has significant implications for intelligent machines.
Researchers found that chasing schools of prey at high speed leads to higher attack rates and increased hunting success for striped marlin. The study shows that group hunting is advantageous for predatory fish, as it allows them to isolate and catch individual prey more easily.
Researchers developed a computational model to understand key decision-making processes, showing how group rewards improve performance. A videogame model inferred sequences of decisions from visual data, revealing the importance of balancing exploration and resource usage in collective behavior.
Researchers found that genetically identical Amazon mollies exhibit differences in offspring size and reproductive output, indicating varying levels of biological fitness. The study suggests that epigenetics, stochasticity, and micro-environmental factors play a role in the emergence of individuality.
Researchers at Technische Universität Berlin demonstrated that fish schools operate at criticality, a state of optimal alertness similar to the brain. This allows them to process external stimuli and transmit information over long distances, enabling coordinated responses.
Researchers found that sheep flocks move in an intermittent and democratic way, with individuals taking turns as group leaders. This allows the flock to benefit from both hierarchical and democratic mechanisms, enabling optimal navigation of complex environments.
