Cognitive biology

Cognitive biology is an emerging science that regards natural cognition as a biological function. It is based on the theoretical assumption that every organism—whether a single cell or multicellular—is continually engaged in systematic acts of cognition coupled with intentional behaviors, i.e., a sensory-motor coupling. That is to say, if an organism can sense stimuli in its environment and respond accordingly, it is cognitive. Any explanation of how natural cognition may manifest in an organism is constrained by the biological conditions in which its genes survives from one generation to the next. And since by Darwinian theory the species of every organism is evolving from a common root, three further elements of cognitive biology are required: (i) the study of cognition in one species of organism is useful, through contrast and comparison, to the study of another species’ cognitive abilities; (ii) it is useful to proceed from organisms with simpler to those with more complex cognitive systems, and (iii) the greater the number and variety of species studied in this regard, the more we understand the nature of cognition.

While cognitive science endeavors to explain human thought and the conscious mind, the work of cognitive biology is focused on the most fundamental process of cognition for any organism. In the past several decades, biologists have investigated cognition in organisms large and small, both plant and animal. “Mounting evidence suggests that even bacteria grapple with problems long familiar to cognitive scientists, including: integrating information from multiple sensory channels to marshal an effective response to fluctuating conditions; making decisions under conditions of uncertainty; communicating with conspecifics and others (honestly and deceptively); and coordinating collective behaviour to increase the chances of survival.” Without thinking or perceiving as humans would have it, an act of basic cognition is arguably a simple step-by-step process through which an organism senses a stimulus, then finds an appropriate response in its repertoire and enacts the response. However, the biological details of such basic cognition have neither been delineated for a great many species nor sufficiently generalized to stimulate further investigation. This lack of detail is due to the lack of a science dedicated to the task of elucidating the cognitive ability common to all biological organisms. That is to say, a science of cognitive biology has yet to be established. A prolegomena for such science was presented in 2007 and several authors have published their thoughts on the subject since the late 1970s. Yet as the examples in the next section suggest, there is neither consensus on the theory nor widespread application in practice. Although the two terms are sometimes used synonymously, cognitive biology should not be confused with the biology of cognition in the sense that it is used by adherents to the Chilean School of Biology of Cognition. Also known as the Santiago School, the biology of cognition is based on the work of Francisco Varela and Humberto Maturana, who crafted the doctrine of autopoiesis. Their work began in 1970 while the first mention of cognitive biology by Brian Goodwin (discussed below) was in 1977 from a different perspective. 'Cognitive biology' first appeared in the literature as a paper with that title by Brian C. Goodwin in 1977. There and in several related publications Goodwin explained the advantage of cognitive biology in the context of his work on morphogenesis. He subsequently moved on to other issues of structure, form, and complexity with little further mention of cognitive biology. Without an advocate, Goodwin’s concept of cognitive biology has yet to gain widespread acceptance. Aside from an essay regarding Goodwin’s conception by Margaret Boden in 1980, the next appearance of ‘cognitive biology’ as a phrase in the literature came in 1986 from a professor of biochemistry, Ladislav Kováč. His conception, based on natural principles grounded in bioenergetics and molecular biology, is briefly discussed below. Kováč’s continued advocacy has had a greater influence in his homeland, Slovakia, than elsewhere partly because several of his most important papers were written and published only in Slovakian.
