Beyond stimulus cues and reinforcement signals: A new approach to animal metacognition
Some metacognition paradigms for nonhuman animals encourage the alternative explanation that animals avoid difficult trials based only on reinforcement history and stimulus aversion. To explore this possibility, we placed humans and monkeys in successive uncertainty-monitoring tasks that were qualitatively different, eliminating many associative cues that might support transfer across tasks. In addition, task transfer occurred […]
Consciousness, emotion and animal welfare: insights from cognitive science
The assumption that animals are conscious and capable of experiencing negative sensations and emotions is at the core of most people’s concerns about animal welfare. Investigation of this central assumption should be one goal of animal welfare science. We argue that theory and techniques from cognitive science offer promising ways forward. Evidence for the existence […]
Orangutans (Pongo abelii) “play the odds”: Information-seeking strategies in relation to cost, risk, and benefit
Recent research has examined whether animals possess metacognition, or the ability to monitor their knowledge states. However, the extent to which animals actively control their knowledge states is still not well delineated. Although organisms might be capable of seeking information when it is lacking, it does not mean that it is always adaptive to do […]
