A number of ways of taxonomizing human learning have been proposed. We examine the evidence for one such proposal, namely, that there exist independent explicit and implicit learning systems. This combines two further distinctions, (1) between learning that takes place with versus without concurrent awareness, and (2) between learning that involves the encoding of instances (or fragments) versus the induction of abstract rules or hypotheses. Implicit learning is assumed to involve unconscious rule learning. We examine the evidence for implicit learning (...) derived from subliminal learning, conditioning, artificial grammar learning, instrumental learning, and reaction times in sequence learning. We conclude that unconscious learning has not been satisfactorily established in any of these areas. The assumption that learning in some of these tasks (e.g., artificial grammar learning) is predominantly based on rule abstraction is questionable. When subjects cannot report the rules that govern stimulus selection, this is often because their knowledge consists of instances or fragments of the training stimuli rather than rules. In contrast to the distinction between conscious and unconscious learning, the distinction between instance and rule learning is a sound and meaningful way of taxonomizing human learning. We discuss various computational models of these two forms of learning. (shrink)
Over the past 40 years, scholars and practitioners of public relations have often cast public relations workers in the role of the public relations-person-as-corporate-conscience. This work, however, maintains that this construct is so problematic that invoking it is of negligible use in addressing ethical issues that emerge during a crisis. In fact, a complex crisis, such as the Jahi McMath “brain death” case at Children’s Hospital Oakland, demonstrates the need to abandon the PRPaCC construct to better engage affected stakeholders, including (...) “outsiders” to the organization, who often determine whether an organization is facing a crisis. Through an examination of both the concept of the PRPaCC and the McMath crisis, this work makes the case for moving beyond the PRPaCC construct in favor of a more modest role for the public relations person: facilitating widespread ethical deliberation and discussion throughout an organization, potentially helping the organization alleviate concerns that contribute to crises.

In A Theory of Justice, John Rawls devised the method of reflective equilibrium in an attempt to broker consensus between ethical approaches emphasising individual moral judgements, and those emphasising moral principles, expanding this method in the later paper; “The Independence of Moral Theory”, to produce wide reflective equilibrium. In a number of essays compiled in Justice and Justification, Norman Daniels articulated a more comprehensive version of Rawls's methodology in response to something of a similar struggle within contemporary bioethics, between (...) those bioethical approaches emphasising individual moral judgements, those emphasising bioethical principles and those emphasising bioethical theory; the casuists, the principlists and the descriptivists respectively. In addition to the level of considered moral judgements and that of moral principles that comprise Rawls's reflective equilibrium, Daniels's model proposes a third level of interconnecting background theories in order to incorporate the three dominant strands of contemporary bioethics, to broker consensus between those whose considered moral judgements are in conflict, and to guard against the endpoint of the reflective equilibrium being overly determined by these judgements. However, it is unclear whether his method aids the objectives he set, or whether it in fact hinders them. (shrink)
Nature and Narrative is the launch volume in a new series of books entitled International Perspectives in Philosophy and Psychiatry. The series will aim to build links between the sciences and humanities in psychiatry. Our ability to decipher mental disorders depends to a unique extent on both the sciences and the humanities. Science provides insight into the 'causes' of a problem, enabling us to formulate an 'explanation', and the humanities provide insight into its 'meanings' and helps with our 'understanding'. Psychiatry, (...) if it is to develop as a balanced discipline, must draw on input from both of these spheres. Nature (for causes) and Narrative (for meanings) will help define the series as a whole by touching on a range of issues relevant to this 'border country'. With contributions from an international star-studded cast, representing the field of psychiatry, psychology and philosophy, this volume will set the scene for this new interdisciplinary field. This will be of interest to all those with practical experience of mental health issues, whether as providers or as users/consumers of services, as well as to philosophers, social scientists, and bioethicists.

While working on various medieval philosophers, I have noticed an affinity between their remarks on the reasonableness of accepting propositions that are not matters of proof and strict deduction and St. John Henry Newman’s remarks that we accept unconditionally and rightly everyday ordinary propositions without calibrating them to demonstrable arguments. In particular, Cardinal Matthew of Aquasparta and Blessed John Duns Scotus both claim there is a sense in which assent to everyday propositions is tantamount to knowledge, even though (...) there is no adequate argumentation or demonstrative reasoning compelling us to assent to such propositions. Newman’s distinction between notional and real apprehension of propositions, notional and real assents, and his insistence on the existence of real assents to propositions that are not necessarily proved, or in some cases provable, seem, at first glance, a case parallel to that of the medieval philosophers we have mentioned.
