Invertebrate learning and cognition: relating phenomena to neural substrate.

Diverse invertebrate species have been used for studies of learning and comparative cognition. Although we have gained invaluable information from this, in this study we argue that our approach to comparative learning research is rather deficient. Generally invertebrate learning research has focused mainly on arthropods, and most of that within the Hymenoptera and Diptera. Any true comparative ...

Sentience Everywhere

Philosophical understandings of consciousness divide into emergentist positions (when the universe is sufficiently organized and complex it gives rise to consciousness) vs. panpsychism (consciousness pervades the universe). A leading emergentist position derives from autopoietic theory of Maturana and Varela: to be alive is to have cognition, one component of which is sentience. Here, reflectin...

Sentience and Pain in Invertebrates

Evolutionary Biology of Animal Cognition

■ Abstract This review focuses on five key evolutionary issues pertaining to animal cognition, defined as the neuronal processes concerned with the acquisition, retention, and use of information. Whereas the use of information, or decision making, has been relatively well examined by students of behavior, evolutionary aspects of other cognitive traits that affect behavior, including perception,...
