The development of action representation during adolescence was investigated using a visually guided pointing motor task to test motor imagery. Forty adolescents and 33 adults were instructed to both execute and imagine hand movements from a starting point to a target of varying size. Reaction time was measured for both Execution and Imagery conditions. There is typically a close association between time taken to execute and image actions in adults because action execution and action simulation rely on overlapping neural circuitry. (...) Further, representations of actions are governed by the same speed-accuracy trade-off as real actions, as expressed by Fitts’ Law. In the current study, performance on the VGPT in both adolescents and adults conformed to Fitts’ Law in E and I conditions. However, the strength of association between E and I significantly increased with age, reflecting a refinement in action representation between adolescence and adulthood. (shrink)

Ethical sensitivity triggers the entire ethical decision-making process (i.e., recognition of ethical content in work situations). In this article, five factors are examined that affect tax practitioners' professional ethical sensitivity. The five factors that were examined include role conflict, role ambiguity, job satisfaction, professional commitment, and ethical orientation. Ethical content in work situations is examined in relation to professional ethics as enumerated by the American Institute of Certified Public Accountant's (AICPA) Statements on Responsibilities in Tax Practice (SRTP). Utilizing Hunt and (...) Vitell's (1986, 1993) General Theory of Ethics, a model of ethical sensitivity was constructed and empirically tested. Role conflict negatively and job satisfaction positively influenced tax practitioners' ethical sensitivity. Also, the covariates of the tax practitioner's professional risk level and type of employer were found to be significant. The significant factors are job specific. The tax firm may have the best opportunity to positively change a tax practitioner's ethical recognition abilities. Professional accounting organizations may need to evaluate if resources should be used to formulate, maintain, and publicize codes of conduct because of the lack of significance of professional commitment.

In this essay, I use the theological anthropology of the apostle Paul as a diagnostic lens in order to bring into focus some implicit assumptions about human personhood in the goals and methods of treatment with psychotropic medications. I argue that Paul views the body as a mode of participation in larger relational matrices in both vulnerable and vital ways. He thus sees the self as constituted relationally rather than as fundamentally isolated and self-determining. Such an understanding of personhood yields (...) an account of human agency as co-constituted and freedom as interpersonally mediated and sustained. From this perspective, the proper goal for psychiatric medication is the removal of barriers to life-giving human connections; methods of care for persons in psychological distress may include medication, but they also require embodied personal encounter.

The remarks of my exciting and ebullient colleague, John King-Farlow do not clarify what I find most perplexing either in Wittgenstein’s analogy of the builders or in Rhees’ famous comments on it. Professor King-Farlow does, however, lay before us important and challenging allegations as to an incoherent or nonsensical quality of the discussion so far. Before one turns to these allegations, something should be said on behalf of Saint Augustine’s remarks in The Confessions of language-learning.

Nielsen's covert REM process model explains much of the mentation found in REM and NREM sleep, but stops short of postulating an interaction of waking cognitive processes with the dream mechanisms of REM sleep. It ranks with the Hobson et al. paper as a major theoretical advance. The Solms article does not surmount the ever-present problem of defining dreams in a manner conducive to advancing dream theory. Vertes & Eastman review the REM sleep and learning literature, but make questionable (...) assumptions in doing so. [Hobson et al.; Nielsen; Solms; Vertes & Eastman]. (shrink)

Preston & de Waal are understandably cautious in applying their model to autism. They emphasise multiple cognitive impairments in autism, including prefrontal-executive, cerebellar-attention, and amygdala-emotion recognition deficits. Further empirical examination of imitation ability in autism may reveal deficits in the neural and cognitive basis of perception-action mapping that have a specific relation to the empathic deficit.

Untying the Gordian Knot shows how the fundamental notions of process, logic and relations, woven with triads of input-output-context, can be combined with quantum distinctions associated with actuality and potentiality, enabling the leveraging of many advances in philosophy and physics to unravel several long-standing philosophical problems.

Tomasello et al. highlight how in combination cognitive impairments and affective impairments help explain why individuals with autism do not enter fully into human culture. We query whether the motivational component is a later development in human ontogeny and whether the cognitive level of intention reading is intact in autism. A key question is what neuropsychological impairments underlie this cognitive–affective impairment.

ABSTRACT When is it right to enforce medical treatment on a patient who is refusing that treatment? English law recognises two ethical principles as of paramount importance: the autonomy of the patient; and the consequences of not treating compared with treating. The law, by and large, operates these principles in succession. Thus, in the case of a patient refusing treatment, the law asks first, is the patient competent? Only if the answer is no, are the consequences considered. We criticise the (...) position taken by English law and argue, first, that competence is a graded and not a binary concept, and secondly, that the two ethical principles should be applied not sequentially but at the same time. These two ideas form what we have called the balance model. This model could be used for an empirical study of individuals’ ethical beliefs, and in particular to test the hypothesis that the ethical beliefs of most individuals conform to the balance model rather than to the position taken by English law.

This volume presents twelve original essays, by an international team of scholars, on the relation of John Locke's thought to Descartes and to Cartesian philosophers such as Malebranche, Clauberg, and the Port-Royal authors. The essays, preceded by a substantial introduction, cover a large variety of topics from natural philosophy to religion, philosophy of mind and body, metaphysics and epistemology. The volume shows that in Locke's complex relationship to Descartes and Cartesianism, stark opposition and subtle 'family resemblances' are tightly intertwined. Since (...) the turn of the twentieth century, the theory of knowledge has been the main comparative focus. According to an influential historiographical conception, Descartes and Locke form together the spearhead in the 'epistemological turn' of early modern philosophy. In bringing together the contributions to this volume, the editors advocate for a shift of emphasis. A full comparison of Locke's and Descartes's positions should cover not only their theories of knowledge, but also their views on natural philosophy, metaphysics, and religion. Their conflicting claims on issues such as cosmic organization, the qualities and nature of bodies, the substance of the soul, and God's government of the world, are of interest not only in their own right, to take the full measure of Locke's complex relation to Descartes, but also as they allow a better understanding of the continuing epistemological debate between the philosophical heirs of these thinkers.

The United States is one of the most charitable nations, yet comprises some of the most materialistic citizens in the world. Interestingly, little is known about how the consumer trait of materialism, as well as the opposing moral trait of gratitude, influences charitable giving. We address this gap in the literature by theorizing and empirically testing that the effects of these consumer traits on charitable behavior can be explained by diverse motivations. We discuss the theoretical implications, along with implications for (...) charitable organizations, and offer suggestions for future research. (shrink)

We present evidence disputing the hypothesis that memories are processed or consolidated in REM sleep. A review of REM deprivation (REMD) studies in animals shows these reports to be about equally divided in showing that REMD does, or does not, disrupt learning/memory. The studies supporting a relationship between REM sleep and memory have been strongly criticized for the confounding effects of very stressful REM deprivation techniques. The three major classes of antidepressant drugs, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), and (...) selective serotonin reuptake inhibitors (SSRIs), profoundly suppress REM sleep. The MAOIs virtually abolish REM sleep, and the TCAs and SSRIs have been shown to produce immediate (40–85%) and sustained (30–50%) reductions in REM sleep. Despite marked suppression of REM sleep, these classes of antidepressants on the whole do not disrupt learning/memory. There have been a few reports of patients who have survived bilateral lesions of the pons with few lingering complications. Although these lesions essentially abolished REM sleep, the patients reportedly led normal lives. Recent functional imaging studies in humans have revealed patterns of brain activity in REM sleep that are consistent with dream processes but not with memory consolidation. We propose that the primary function of REM sleep is to provide periodic endogenous stimulation to the brain which serves to maintain requisite levels of central nervous system (CNS) activity throughout sleep. REM is the mechanism used by the brain to promote recovery from sleep. We believe that the cumulative evidence indicates that REM sleep serves no role in the processing or consolidation of memory. Key Words: antidepressant drugs; brain stem lesions; dreams; functional imaging; memory consolidation; REM deprivation; REM sleep; theta rhythm. (shrink)

Many people who were Saturday Night Live fans in the 1990s recall the firing of Norm Macdonald as a watershed moment. In exploring theories about why people employ humor, they just might be able to discover the motivations behind Macdonald's firing. Macdonald offered a different assessment of his firing in an oral history of Saturday Night Live, saying that it came down to a philosophical disagreement between NBC management and himself about the goal of “Weekend Update.” Macdonald's requirement that laughter (...) be involuntary tracks well with Max Eastman's philosophical theory of humor known as play theory. Sigmund Freud's Relief Theory suggests that the main goal of humor and laughter is to relieve pent up stresses and mental strain that people carry around with them. The most important difference between humor‐as‐relief and play theory is that in play theory the release is a positive consequence, but not the intended goal. (shrink)

We believe that this has been a constructive debate on the topic of memory consolidation and REM sleep. It was a lively and spirited exchange – the essence of science. A number of issues were discussed including: the pedestal technique, stress, and early REMD work in animals; REM windows; the processing of declarative versus procedural memory in REM in humans; a mnemonic function for theta rhythm in waking but not in REM sleep; the lack of cognitive deficits in patients on (...) antidepressant drugs that suppress or eliminate REM sleep; the disposition of conscious (dreams) and nonconscious material of REM sleep; and finally our theory of REM sleep. Although our position was strongly challenged, we still hold that REM sleep serves no role in the processing and consolidation of memory. (shrink)

SummaryCross-sectional studies in Australia and the Philippines and a longitudinal prospective study in a selected Australian sample of breast-feeding mothers have shown that basal serum prolactin concentrations are elevated during 15–21 months of lactational amenorrhoea.A predictive model of serum PRL levels and return of cyclic ovarian activity during full breast-feeding, partial breast-feeding and weaning has been developed from the results of breast-feeding behaviour and serum PRL, gonadotrophin and oestradiol measurements in 34 mothers breast-feeding on demand for a mean of 67 (...) weeks.Breast-feeding patterns influence serum PRL levels. Important factors during full breast-feeding are the age of the baby, the longest interval between feeds at night and total 24-hr suckling time, and following the introduction of supplements, the mean interval between feeds, together with the total 24-hr suckling time and the number of solid supplements per day.The precise mechanisms whereby breast-feeding regulates cyclic ovarian activity remain unknown. Gonadotrophin secretion appears to be quantitatively normal, but qualitative changes, secondary to altered hypothalamic activity, may be the most important factor. A direct inhibitory effect of PRL on ovarian follicular development and steroidogenesis remains possible.Ovulation with a normal luteal phase is probable for 30% of breast-feeding mothers before the first menses, but is unlikely before 6 months, provided breast-feeding is frequent day and night.Measurement of serum PRL is a sensitive index of the return of menstruation and fertility during lactation in the population studied.

Through both an historical and philosophical analysis of the concept of possibility, we show how including both potentiality and actuality as part of the real is both compatible with experience and contributes to solving key problems of fundamental process and emergence. The book is organized into four main sections that incorporate our routes to potentiality: potentiality in modern science [history and philosophy; quantum physics and complexity]; Relational Realism [ontological interpretation of quantum physics; philosophy and logic]; Process Physics [ontological interpretation of (...) relativity theory; physics and philosophy]; on speculative philosophy and physics [limitations and approximations; process philosophy]. We conclude that certain fundamental problems in modern physics require complementary analyses of certain philosophical and metaphysical issues, and that such scholarship reveals intrinsic features and limits of determinism, potentiality and emergence that enable, among others, important progress on the quantum theory of measurement problem and new understandings of emergence.

The Strange Genius of Mr. O is at once the biography of a remarkably odd celebrity--a gaunt, opium-addicted Scottish orator who lectured in a toga--and a tour of the fledgling United States. James Ogilvie arrived in the United States in 1793 as an educated, impoverished, and deeply ambitious teacher. By the time he returned to Britain in 1819, he was a celebrity known simply as "Mr. O" who counted the nation's leading politicians, writers, and intellectuals among his admirers. Following Ogilvie (...) on lecture tours from the Atlantic coast as far west as frontier Kentucky, Eastman reconstructs his path to renown, explaining how and why Ogilvie mattered to the citizens of the early republic. His example inspired countless men and more than a few women to become amateur orators and helped inaugurate America's golden age of oratory. At a time when Americans were eager for national unity, Ogilvie and his audiences hoped that eloquence might knit a divided public together--that educated, elevated oratory might provide a bedrock for citizenship and civic belonging. In Eastman's hands, Ogilvie's remarkable life story has as much to tell us about a fascinating man as it has to reveal about the nation he helped fashion. (shrink)

As the issue of marketing's social responsibility grows in significance, the topic of materialism surfaces. While many marketing efforts encourage materialism, the materialism that is encouraged may have negative societal effects. An understanding of the effects of materialism on individuals, families, society, etc., is important in evaluating whether or not it is socially irresponsible for marketers to encourage materialism. However, the adequate empirical work has not yet been done on the overall effects of materialism. The current paper asks and addresses (...) one important empirical question in this area. Do consumers who are more materialistic have different ethical standards than those who are not? Empirical evidence is presented which would indicate that materialism is negatively correlated with people's higher ethical standards as consumers. The implications for this in understanding social responsibility are discussed. (shrink)

The result of 10 years' worth of painstaking research, this volume, originally published in 1926 is a sympathetic critique of certain phases of revolutionary dictatorship in Russia. Among other things it focusses on the philosophy and psychology of Marxism, Marxian economics, Bolshevism, the philosophy of Lenin and his role as an engineer of revolution, the Mensheviks, and the anarchist contribution.

The ongoing research program of process thought meets some of its most crucial tests in efforts towards a comprehensive philosophy of nature. Contributors to the two special focus issues on natural science for the Process Studies journal provide many examples of such tests and commentary that reflect contemporary scientific thought. A core element of modern scientific methodology is the search for invariant, physical relationships that simplify our understanding of complex systems. In addition to a preference for some form of critical (...) realism and intersubjective testability, scientists search for relationships that are both universal and repeatable. Indeed, the very success of this approach has led to more and more frequent use of 'event/process' versus 'substance/thing' language in the sciences. (edited). (shrink)
