A recent naturalistic epistemological account suggests that there are three nested basic forms of knowledge: procedural knowledge-how, conceptual knowledge-what, and propositional knowledge-that. These three knowledge-forms are grounded in cognitive neuroscience and are mapped to procedural, semantic, and episodic long-term memory respectively. This article investigates and integrates the neuroscientifically grounded account with knowledge-accounts from cognitive ethology and cognitive psychology. It is found that procedural and semantic memory, on a neuroscientific level of analysis, matches an ethological reliabilist account. This formation also matches (...) System 1 from dual process theory on a psychological level, whereas the addition of episodic memory, on the neuroscientific level of analysis, can account for System 2 on the psychological level. It is furthermore argued that semantic memory and the cognitive ability of categorization are linked to each other, and that they can be fruitfully modeled within a conceptual spaces framework.

The end of the 20th century became a milestone for the progress of Neurosciences and their contribution to a better understanding of the physiological mechanisms involved in cognition, mood and human behavior. Because of this, it was possible not only to intervene some of the aforementioned aspects with therapeutic purposes, but more recently they became objects of study in researches with a more pragmatic nature, such as clinical researches involving persons with no mental or physical disorders, but who require to (...) prove remarkable abilities for executive functions, e.g., soldiers, pilots, students, among others. On the other hand, there is an ethical and scientific debate over the interest to evaluate certain psychotropic medications due to its possible sideeffects as cognitive enhancers in healthy subjects that, because of their social status, might be benefited in their social, academic or work life by developing a better mental performance. Therefore, the article aims to present from the perspective of Bioethics and Psychopharmacology some aspects of the research in Neurosciences that might throw light upon the scientific debate oriented towards the social significance of such clinical studies and their possible consequences for the future.
