Abstract Christopher Gauker has argued that a cause?effect analysis of the acquisition of communication skills in chimpanzees is adequate to describe the data reported in our work at the Language Research Center. I agree that the cause?effect approach to language function is the only viable method of analyzing language. Language must be studied as a process that functions to organize behavior between two or more individuals. However, the problem of language understanding is not addressed satisfactorily by the perspective offered by (...) Gauker. Some more recent work, particularly with the pygmy chimpanzee ?Kanzi?, is now beginning to explicate a cause?effect analysis of language comprehension. It is argued that in the young chimpanzee, as with children, language comprehension is the driving force underlying the language acquisition process. It is further argued that the transition from comprehension to production is made possible by the capacity for goal?directed observational imitation. (shrink)

This book takes a fascinating look at the linguistic, psychological, and anthropological implications of Sue Savage-Rumbaugh's work with Kanzi--a bonobo who has achieved stunning cognitive and linguistic skills.

This article questions traditional approaches to the study of primate cognition. Because of a widespread assumption that cognition in non-human primates is genetically encoded, these approaches neglect how profoundly apes’ cultural rearing experiences affect test results. We describe how three advanced cognitive abilities – imitation, theory of mind and language – emerged in bonobos maturing in a Pan/Homo culture.

This article questions traditional experimental approaches to the study of primate cognition. Beecuse of a widespread assumption that cognition in non-human primates is genetically encoded and “natural,” these approaches neglect how profoundly apes’ cultural rearing experiences affect test results. We deseribe how three advanced cognitive abilities - imitation, theory of mind and language - emerged in bonobos maturing in a bi-species Pan/Homo culture, and how individual rearing differences led to individual forms of these abilities. These descriptions are taken from a (...) rich ethnographic material, and we argue for the scientific superiority of participant-based ethnographic studies of primate cognition in shared Pan/Homo cultures.

First paragraph: Ernst von Glasersfeld's contributions to the LANA Project (the Language Analogue Project) were very important to its seven years of success, 1971--1977, during which the effort was led by the senior author of this paper... Indeed, his contributions have helped perpetuate research into the language skills of apes and sea mammals to this day. Ernst was a member of the original team of 1970 that formulated the proposal to the National Institutes of Health for four years' funding to (...) develop a computer-monitored keyboard-situation appropriate to research on the language skills of which the great apes might be capable.

Harry Harlow is credited with the discovery of learning set, a process whereby problem solving becomes essentially complete in a single trial of training. Harlow described that process as one that freed his primates from arduous trial-and-error learning. The capacity of the learner to acquire learning sets was in positive association with the complexity and maturation of their brains. It is here argued that Harlow's successful conveyance of learning-set phenomena is of historic significance to the philosophy of psychology. Learning set (...) is said to reflect the affirmation or rejection of hypotheses. Hypotheses are generated by the learner's brain, not its muscles. Thus, learning-set research served to advance the perspective that even nonhuman primates think and that their thinking reflects the active processing of information accrued from efforts to solve problems. Their learning processes are not simply the strengthening of some motor responses over others. Hence, learning-set research served to advance studies of animals as rational agents. This trend is serving to supplant the radical-behavioristic models, formulated earlier this century, with models predicated on rational processes for animals' complex learning and behavior. (shrink)

We suggest that the phenomenon of uncertainty monitoring in nonhuman animals contributes richly to the conception of nonhuman animals' self-monitoring. We propose that uncertainty may play a role in the emergence of new forms of behavior that are adaptive. We recommend that Smith et al. determine the extent to which the uncertain response transfers immediately to other test paradigms.

Culture can be said to be about the business of 'self-replication'. From the moment of conception, it impresses its patterns and rhythms on the developing, infinitely plastic neuronal substrate of the fetal organism. It shapes this substrate to become preferentially sensitive to its patterns and thus to seek to replicate them as an adult. This process of neural shaping continues throughout life as the capacity of the brain to reorganize itself according to the uses to which it addresses itself never (...) ceases. The extraordinary capacity of culture to extract different abilities from the biological form is clearly manifest in the lexical, vocal, tool manufacture, and writing capabilities emerging in bonobos raised in a Pan/Homo culture. These findings render moot old questions regarding the innate limits of the ape brain. They raise instead far more productive questions about the form and function of the perpetual dance that is constantly taking place between plastic neuronal systems and their external culturally devised ways of being.

We comment on the similarities and differences of Mitchell et al.'s framework for understanding classical and operant conditioning and the theoretical framework put forth by Rumbaugh et al. (2007). We propose that all nonhuman and human learning may be based on amalgams created by co-occurring stimuli that share their response-eliciting properties and that these amalgams may be propositional in nature.

Bien que la dichotomie classique homme/animal continue de sous-tendre la pensée scientifique occidentale, la génétique moléculaire prouve que les humains sont bien plus proches des chimpanzés et des bonobos que ne pouvaient le supposer les chercheurs en se fondant seulement sur l’évidence anatomique, il y a quelques décennies. Le degré de similitude de l’ADN entre humains, bonobos et chimpanzés autorise à nous classer tous trois comme espèces-sœurs. Ce qui signifie, aussi étrange que cela pui..

Plotinus holds an important position in the history of late ancient philosophy on the concept of human agency. On the one hand, he follows Plato in regarding a human agent as one who self-identifies with the rational soul, becomes one from many, and acts from reason (Republic, 443de). On the other hand, due to the view characteristic of the second century CE that destiny causally determines the sensible world and sophisticated debates concerning freedom and determinism up to, and during, the (...) second century CE, Plotinus develops Plato’s view further in an effort to meet the challenges posed by earlier determinists. The position he develops in the Enneads is a dynamic synthesis of Platonic, Peripatetic, Stoic, and Middle-Platonic theorizing on human causation that shows how one can be a self-determining agent even while living in a world governed by destiny. I argue that the key to understanding Plotinus’ theory of human agency is to understand the role that consciousness plays since he holds that in order to be the sole causal source of our actions, and therefore truly self-determining, we must derive our premises for action from Intellect. Important for my purposes is his peculiar view that Intellect is also “in ourselves” (V.1.10.5-8) and can be reached by turning inwards and ascending upwards which is possible through possessing a unique mode of consciousness, namely awareness (sunaisthēsis).
