We observe that approaches to intersubjectivity, involving mirror neurons and involving emulation and prediction, have eclipsed discussion of those same mechanisms for achieving coordination between the two hemispheres of the human brain. We explore some of the implications of the suggestion that the mutual modelling of the two situated hemispheres is a productive place to start in understanding the phylogenetic and ontogenetic development of cognition and of intersubjectivity.

Cognitive science depends on abstractions made from the complex reality of human behaviour. Cognitive scientists typically wish the abstractions in their theories to be universals, but seldom attend to the ontology of universals. Two sorts of universal, resulting from Galilean abstraction and materialist abstraction respectively, are available in the philosophical literature: the abstract universal—the one-over-many universal—is the universal conventionally employed by cognitive scientists; in contrast, a concrete universal is a material entity that can appear within the set of entities it (...) describes, of which it represents the essential, paradigmatic case. The potential role of concrete universals in cognitive science is discussed. (shrink)

We argue that models of reading should be based on anatomical reality, namely, the fact that both eyes are used in reading; and the observation that the human fovea is precisely vertically split, and projects each half of a fixated word to the contralateral hemisphere.

Although endorsing the authors’ concentration on the issue of abstraction, I critique the philosophical nature of their abstract–concrete dimension, their view of the brain–world barrier, and their implicit positivist one-way hierarchy that has abstraction as the goal.

Pulvermüller's account of lexical representation has implications for visual word recognition, given the claim we make that a foveally presented word is precisely split and contralaterally projected to the two hemispheres, and that this splitting conditions the whole process of visual word recognition. This elaboration of Pulvermüller's account raises issues of hemispheric differences and collaboration.

We urge caution in generalising from content words to function words, in which lexical-to-phonemic feedback might be more likely. Speech perception involves more than word recognition; feedback might be outside the narrow logic of word identification but still be present for other purposes. Finally, we raise the issue of evidence from imaging studies of auditory hallucination.

The use of the symbol ∨for disjunction in formal logic is ubiquitous. Where did it come from? The paper details the evolution of the symbol ∨ in its historical and logical context. Some sources say that disjunction in its use as connecting propositions or formulas was introduced by Peano; others suggest that it originated as an abbreviation of the Latin word for “or,” vel. We show that the origin of the symbol ∨ for disjunction can be traced to Whitehead and (...) Russell’s pre-Principia work in formal logic. Because of Principia’s influence, its notation was widely adopted by philosophers working in logic (the logical empiricists in the 1920s and 1930s, especially Carnap and early Quine). Hilbert’s adoption of ∨ in his Grundzüge der theoretischen Logik guaranteed its widespread use by mathematical logicians. The origins of other logical symbols are also discussed. (shrink)

Grapheme-colour synaesthetes experience unusual colour percepts when they encounter letters and/or digits. Studies of English-speaking grapheme-colour synaesthetes have shown that synaesthetic colours are sometimes triggered by rule-based linguistic mechanisms . In contrast, little is known about synaesthesia in logographic languages such as Chinese. The current study shows the mechanisms by which synaesthetic speakers of Chinese colour their language. One hypothesis is that Chinese characters might be coloured by their constituent morphological units, known as radicals, and we tested this by eliciting (...) synaesthetic colours for characters while manipulating features of the radicals within them. We found that both the function and position of radicals influence the nature of the synaesthetic colour generated. Our data show that in Chinese, as in English, synaesthetic colours are influenced by systematic rules, rather than by random associations, and that these rules are based on existing psycholinguistic mechanisms of language processing.

The target article skillfully evaluates data on mental disorders in relation to predictions from evolutionary genetic theories of neutral evolution, balancing selection, and polygenic mutation-selection balance, resulting in a negative outlook for the likelihood of success finding genes for mental disorders. Nevertheless, new conceptualizations, methods, and continued interactions across disciplines provide hope.

Studies of linguistic synaesthesias in English have shown a range of fine-grained language mechanisms governing the associations between colours on the one hand, and graphemes, phonemes and words on the other. However, virtually nothing is known about how synaesthetic colouring might operate in non-alphabetic systems. The current study shows how synaesthetic speakers of Mandarin Chinese come to colour the logographic units of their language. Both native and non-native Chinese speakers experienced synaesthetic colours for characters, and for words spelled in the (...) Chinese spelling systems of Pinyin and Bopomo. We assessed the influences of lexical tone and Pinyin/Bopomo spelling and showed that synaesthetic colours are assigned to Chinese words in a non-random fashion. Our data show that Chinese-speaking synaesthetes with very different native languages can exhibit both differences and similarities in the ways in which they come to colour their Chinese words.

Although researchers have begun to examine how firms manage their entire web of stakeholder relationships, the component relationships also require theoretical and empirical examination. Several studies have found that Employee Stock Ownership Plans (ESOPs) have a positive impact on firm performance. The authors explain these results by hypothesizing that ESOPs, when combined with employee participation programs, forge a stakeholder relationship between management and employees. The authors offer criteria for identifying stakeholder relationships, provide background on ESOPs, analyze why they contribute to (...) establishing such a relationship, and examine how published empirical research supports this analysis. The authors conclude by suggesting directions for future research. (shrink)

This paper reviews the literature concerning the neural correlates of the self, the relationship between self and memory and the profile of memory impairments in Alzheimer’s disease and explores the relationship between the preservation of the self and anosognosia in this condition. It concludes that a potential explanation for anosognosia in AD is a lack of updating of personal information due to the memory impairments characteristic of this disease. We put forward the hypothesis that anosognosia is due in part to (...) the “petrified self.”. (shrink)

The results of an exploratory study examining the role of trust in stakeholder satisfaction are reported. Customers, stockholders, and employees of financial institutions were surveyed to identify management behaviors that lead to stakeholder satisfaction. The factors critical to satisfaction across stakeholder groups are the timeliness of communication, the honesty and completeness of the information and the empathy and equity of treatment by management.

In his writings Jim Marshall has helpfully emphasized such Wittgensteinian themes as the multiplicity of language games, the deconstruction of ‘certainty,’ and the contexts of power that underlie discursive systems. Here we focus on another important legacy of Wittgenstein's thinking: his insistence that human activity is rule‐governed. This idea foregrounds looking carefully at the world of education and learning, as against the empirical search for new psychological or other facts. It reminds us that we need to consider, in Peter Winch's (...) words, ‘what it makes sense to say’ about certain educational phenomena, and how these meanings stand against understanding a wider form of life. This insight has important implications for doing educational research, and we examine some of these. (shrink)

Conversations with patients and families about the allow-natural-death (AND) order, along with the standard do-not-resuscitate (DNR) order during end-of-life (EOL) decision-making, may create engagement and understanding while promoting care that can be defended using enduring notions of autonomy, beneficence, and professional duty. Ethical, legal, and pragmatic issues surrounding EOL care decision-making seem to suggest discussion of AND orders as one strategy clinicians could consider at the individual practice level and at institutional levels. A discussion of AND orders, along with traditional (...) DNR orders is presented. This is followed by argument and counter-argument focused on ethical, legal, and practical issues germane to EOL care decision-making associated with use of AND orders. (shrink)

We offer a systematic examination of propensity interpretations of fitness, which emphasizes the role that fitness plays in evolutionary theory and takes seriously the probabilistic character of evolutionary change. We distinguish questions of the probabilistic character of fitness from the particular interpretations of probability which could be incorporated. The roles of selection and drift in evolutionary models support the view that fitness must be understood within a probabilistic framework, and the specific character of organism/environment interactions supports the conclusion that fitness (...) must be understood as a propensity rather than as a limiting frequency.

The United Nations' designation of 1979 as the International Year of the Child marked the first global effort undertaken to heighten awareness of the special needs of children. Activities initiated during this special year were designed to promote purposive and collaborative actions for the benefit of children throughout the world. Michigan State University's celebration of the International Year of the Child was held from Septem ber 1979 through June 1980. A variety of activities focused attention on the multiplicity of factors (...) affecting the welfare of today's children as well as the children of the future. Many people involved with the university were concerned that benefits to children continue beyond the official time allocated to the celebration. The series Child Nurturance is one response to this concern. The first five volumes of Child Nurturance reflect directly the activities held on the Michigan State University campus and consist of original contributions from guest speakers and invited contributors. Subsequent biennial volumes will present original contributions from individuals representing such fields as anthropology, biology, education, human ecology, psychology, philosophy, sociology, and medicine. We hope the material presented in these volumes will promote greater understanding of children and encourage interdisciplinary inquiry into the individual, family, societal and cultural variables which influence their welfare and development. We would. like to express both our thanks and our admiration for who not only typed the camera-ready copy for each of Margaret Burritt the volumes, but also served as general manager of the entire project.
