The first claim in the target article was that there is as yet no transparent, causal account of the relations between consciousness and brain-and-behaviour. That claim remains firm. The second claim was that the contents of consciousness consist, psychologically, of the outputs of a comparator system; the third consisted of a description of the brain mechanisms proposed to instantiate the comparator. In order to defend these claims against criticism, it has been necessary to clarify the distinction between consciousness-as-such and the (...) contents of consciousness, to widen the description of the neural machinery instantiating the comparator system, and to clarify the relationship between the contents of consciousness in the here-and-now and episodic memory.

Cognitive science uses the notion of computational information processing to explain cognitive information processing. Some philosophers have argued that anything can be described as doing computational information processing; if so, it is a vacuous notion for explanatory purposes.An attempt is made to explicate the notions of cognitive information processing and computational information processing and to specify the relationship between them. It is demonstrated that the resulting notion of computational information processing can only be realized in a restrictive class of dynamical (...) systems called physical notational systems (after Goodman's theory of notationality), and that the systems generally appealed to by cognitive science-physical symbol systems-are indeed such systems. Furthermore, it turns out that other alternative conceptions of computational information processing, Fodor's (1975) Language of Thought and Cummins' (1989) Interpretational Semantics appeal to substantially the same restrictive class of systems.

J.H. van den Berg was a member of the Utrecht school of phenomenology that flourished in Holland during the 1950s and early 1960s. He was a psychiatrist who had a private practice and he taught at the University of Leiden. Along with other members of the Utrecht school, not all of whom were psychiatrists, he was among the first to apply the insights drawn from existential-phenomenological philosophy to psychology and psychiatry. As with the philosophers, he emphasized that subjectivity was engaged (...) with the world and its activities had to be described. He emphasized that insights into experience as lived, or the phenomenal level, was what was critical for psychologists to understand. (shrink)

Four research strategies currently employed by mainstream psychologists in researching the experiences and behaviors of human subjects are criticized for diminishing the presence of subjectivity. Two perspectives that tend to exaggerate subjectivity are also criticized. A balanced approach to subjectivity is offered that: acknowledges a theoretical perspective that recognizes that there are invisible or nonsensorial characteristics of subjectivity that have to be theoretically appropriated, and that emphasizes the intersubjective dimension as being critical for properly assessing a balanced approach to human (...) subjectivity. A subject-dependent perspective that can efface its own interests is the attitude that is required for the achievement of objectivity. (shrink)

A common misunderstanding of the selected effects theory of function is that natural selection operating over an evolutionary time scale is the only functionbestowing process in the natural world. This construal of the selected effects theory conflicts with the existence and ubiquity of neurobiological functions that are evolutionary novel, such as structures underlying reading ability. This conflict has suggested to some that, while the selected effects theory may be relevant to some areas of evolutionary biology, its relevance to neuroscience is (...) marginal. This line of reasoning, however, neglects the fact that synapses, entire neurons, and potentially groups of neurons can undergo a type of selection analogous to natural selection operating over an evolutionary time scale. In the following, I argue that neural selection should be construed, by the selected effect theorist, as a distinct type of function-bestowing process in addition to natural selection. After explicating a generalized selected effects theory of function and distinguishing it from similar attempts to extend the selected effects theory, I do four things. First, I show how it allows one to identify neural selection as a distinct function-bestowing process, in contrast to other forms of neural structure formation such as neural construction. Second, I defend the view from one major criticism, and in so doing I clarify the content of the view. Third, I examine drug addiction to show the potential relevance of neural selection to neuroscientific and psychological research. Finally, I endorse a modest pluralism of function concepts within biology. (shrink)

Gray has expanded his account of schizophrenia to explain consciousness as well. His theory explains neither phenomenon adequately because he treats individual minds in isolation. The primary function of consciousness is to permit high level interactions with other conscious beings. The key symptoms of schizophrenia reflect a failure of this mechanism.

The concept of emotional intelligence has grown in popularity over the last two decades, generating interest both at a social and a professional level. Concurrent developments in nursing relate to the recognition of the impact of self‐awareness and reflexive practice on the quality of the patient experience and the drive toward evidence‐based patient centred models of care. The move of nurse training into higher education heralded many changes and indeed challenges for the profession as a whole. Traditionally, nurse education has (...) been viewed as an essentialist education, the main emphasis being on fitness for practice and the statutory competencies. However, the transfer into the academy confronts the very notion of what constitutes this fitness for practice.Many curricula now make reference in some way to the notion of an emotionally intelligent practitioner, one for whom theory, practice and research are inextricably bound up with tacit and experiential knowledge. In this paper we argue that much of what is described within curriculum documentation is little more than rhetoric when the surface is scratched. Further, we propose that some educationalists and practitioners have embraced the concept of emotional intelligence uncritically, and without fully grasping the entirety of its meaning and application. We attempt to make explicit the manner in which emotional intelligence can be more realistically and appropriately integrated into the profession and conclude by suggesting a model of transformatory learning for nurse education.

Rachlin's attack on the internal commitment model rests on the demonstrably false claim that self-punishment does not exist. He is correct that habits are an effective device for solving self-control problems, but his additional claim that they are the only such device makes it hard to explain how good habits develop in the first place. Someone with a self-control problem would always choose the spuriously attractive reward, which, over time, would create bad habits.

Because consciousness has an organizational, or functional, center, Gray supposes that there must be a corresponding physical center in the brain. He proposes further that since this center generates consciousness, ablating it would eliminate consciousness, while leaving behavior intact. But the center of consciousness is simply the product of the functional linkages among sensory input, memory, inner speech, and so on, and behavior.

Heyman's two crucial theses are that people over-value immediate rewards, and that addictive substances “subvert the value of competing commodities.” These perennial ideas were discussed by Plato. Whereas Heyman provides scientific clarification and support for the first, the second remains problematic. I outline how this deficiency might be remedied via evolutionary considerations.

There may be evolutionary as well as economic reasons why organisms generally act impulsively. I discuss this possibility and suggest some follow-up experiments that may clarify the exciting empirical and theoretical contributions made by the experiments discussed in the target article.

Heyman's target article makes a strong case for a behavioral approach to addiction, yet some important assumptions require justification, and promising behavioral alternatives to the author's melioration approach should be considered. In particular, the behavioral economic approach to addiction appears well developed and comprehensive. How does the melioration approach complement or improve on a behavioral economic account?
