Conventionality and aptness are two dimensions of metaphorical sentences thought to play an important role in determining how quick and easy it is to process a metaphor. Conventionality reflects the familiarity of a metaphor whereas aptness reflects the degree to which a metaphor vehicle captures important features of a metaphor topic. In recent years it has become clear that operationalizing these two constructs is not as simple as asking naïve raters for subjective judgments. It has been found that ratings of (...) aptness and conventionality are highly correlated, which has led some researchers to pursue alternative methods for measuring the constructs. Here, in four experiments, we explore the underlying reasons for the high correlation in ratings of aptness and conventionality, and question the construct validity of various methods for measuring the two dimensions. We find that manipulating the processing fluency of a metaphorical sentence by means of familiarization to similar senses of the metaphor (“in vivo conventionalization”) influences ratings of the sentence's aptness. This misattribution may help explain why subjective ratings of aptness and conventionality are highly correlated. In addition, we find other reasons to question the construct validity of conventionality and aptness measures: for instance, we find that conventionality is context dependent and thus not attributable to a metaphor vehicle alone, and we find that ratings of aptness take more into account than they should.

The temporal granularity of consciousness may be far less fine than the real-time information processing mechanisms that underlie our sensitivity to small temporal differences. It is suggested that conscious time perception, like space perception, is subject to errors that belie a unitary underlying representation. E. R. Clay's concept of the “specious present,” an extended moment represented in consciousness, is suggested as an alternative to the more common notion of instantaneous experience that underlies much reasoning based on the “time of arrival” (...) in consciousness.

Increasing complexities facing physicians negotiating the bedside decision continue to fuel the debate over who is the appropriate party to offer ethics consults, should one be needed, during the decision-making process. Some very good arguments have been put forth on behalf of clinical ethicists as being the proper and best party to engage in ethics consultations. However, serious questions remain about the role of the clinical ethicist and his ability to provide the necessary level of objectivity called for in an (...) ethics consult.I argue that the clinician's professional psyche, or mode of thinking as a professional, leaves him little room to maneuver as an objective and detached third party ethics consultant. Several factors are cited and discussed that greatly influence the analyses applied to a case problem by physicians. The most formidable of these factors are habits and the practice of defensive medicine. I conclude that clinical ethicists are less suited for the overall tasks required of an objective consultant in medical cases that appear to involve insurmountable ethical issues. (shrink)

Deep brain stimulation of the subthalamic nucleus is a clinically effective tool for treating medically refractory Parkinson’s disease, but its neural mechanisms remain debated. Previous work has demonstrated that STN DBS results in evoked potentials in the primary motor cortex, suggesting that modulation of cortical physiology may be involved in its therapeutic effects. Due to technical challenges presented by high-amplitude DBS artifacts, these EPs are often measured in response to low-frequency stimulation, which is generally ineffective at PD symptom management. This (...) study aims to characterize STN-to-cortex EPs seen during clinically relevant high-frequency STN DBS for PD. Intraoperatively, we applied STN DBS to 6 PD patients while recording electrocorticography from an electrode strip over the ipsilateral central sulcus. Using recently published techniques, we removed large stimulation artifacts to enable quantification of STN-to-cortex EPs. Two cortical EPs were observed – one synchronized with DBS onset and persisting during ongoing stimulation, and one immediately following DBS offset, here termed the “start” and the “end” EPs respectively. The start EP is, to our knowledge, the first long-latency cortical EP reported during ongoing high-frequency DBS. The start and end EPs differ in magnitude and latency, and the end, but not the start, EP magnitude has a significant relationship to ongoing high gamma power during the EP. These contrasts may suggest mechanistic or circuit differences in EP production during the two time periods. This represents a potential framework for relating DBS clinical efficacy to the effects of a variety of stimulation parameters on EPs. (shrink)

A new motion illusion is discussed in relation to the idea of vision as a Grand Illusion. An experiment shows that this 'Tinkerbell effect' is a good example of a visual illusion supported by low-level stimulus information, but resulting from integration principles probably necessary for normal perception.

Corporate social policy can be viewed as three legs of a tripod: efficient production, stable employment, and a social and political environment that promotes high performance of both workers and managers.Social policy process consists of achieving a balance of corporate interest with other interests in the society. Each policy position taken by the firm alters its relationships with all other interests and creates a new balance. This entails the risk of creating unfriendly interests and losing the support of others, depending (...) on the issue and shift in power. (shrink)

There are problems with both the theoretical logic and the interpretation of data in Christie and Barresi's interesting article. The general pattern of results is easily incorporated into an information-processing framework compatible with Dennett's analysis. In particular, different aspects of the illusory motion event are queried at different times and these aspects are not in conflict, so no revision of conscious content is necessary. Second, too much interpretive weight is placed on an anomalous pair of data points that do not (...) seem fully interpretable within the author's framework and are probably susceptible to one of several alternative interpretations proposed here, though further investigation is necessary.

Although Pessoa et al. imply that many aspects of the filling-in debate may be displaced by a regard for active vision, they remain loyal to naive neural reductionist explanations of certain pieces of psychophysical evidence. Alternative interpretations are provided for two specific examples and a new category of filling-in (of visual detail) is proposed.

The mid-1880s, like the mid-1870s, were a time of considerable turmoil for American workers. Unemployment and wage cuts were widespread and workers responded with strikes, boycotts, union organizing, local labor tickets, and a bewildering variety of reform schemes and ideologies. Perhaps the central event of the 1880s was the Haymarket incident. The bomb and subsequent trial had a broad historical impact, sparking a red scare, blunting the eight-hour movement, establishing the stereotype of anarchists as wildeyed, foreign bombthrowers, and intensifying calls (...) for immigration restriction.

Medicine and Money explores the role of beneficence and cost control in health-care systems. The book's primary concern of morally improving medicine is achieved by dividing the argument into two parts. The first defines the crisis in health-care and justifies beneficence. The second part offers practical suggestions on implementing beneficence into the system. Medicine and Money is one of the few books to provide concrete suggestions on improving the health-care system from the micro level for addressing cost concerns in a (...) morally acceptable manner.

Many human cultural traits become increasingly beneficial as they are repeatedly transmitted, thanks to an accumulation of modifications made by successive generations. But how do later generations typically avoid modifications which revert traits to less beneficial forms already sampled and rejected by earlier generations? And how can later generations do so without direct exposure to their predecessors' behavior? One possibility is that learners are sensitive to cues of non‐random production in others' behavior, and that particular variants (e.g., those containing structural (...) regularities unlikely to occur spontaneously) have been produced deliberately and with some effort. If this non‐random behavior is attributed to an informed strategy, then the learner may infer that apparent avoidance of certain possibilities indicates that these have already been sampled and rejected. This could potentially prevent performance plateaus resulting from learners modifying inherited behaviors randomly. We test this hypothesis in four experiments in which participants, either individually or in interacting dyads, attempt to locate rewards in a search grid, guided by partial information about another individual's experience of the task. We find that in some contexts, valid inferences about another's behavior can be made from partial information, and these inferences can be used in a way which facilitates trait adaptation. However, the benefit of these inferences appears to be limited, and in many contexts—including some which have the potential to make inferring the experience of another individual easier—there appears to be no benefit at all. We suggest that inferring previous behavior from partial social information plays a minimal role in the adaptation of cultural traits. (shrink)

An alternative account of the locus equation phenomenon based on recent theories of speech movement planning is provided. It is similar to Sussman et al.'s account in positing that our productions are tuned to satisfy auditory constraints. It differs by suggesting that the locus equation effect may be an epiphenomenon of a planning process that satisfies simpler auditory constraints.

This thesis maintains that Friedrich Holderlin's poetic thought is a key element not only in the development of Martin Heidegger's philosophical thought from 1929/30 to 1933 but also in his decision to become politically involved with National Socialism. Although Heidegger was familiar with Holderlin's poetry prior to 1929, he did not perceive the significance of the poet's thought and language until he was able to overcome the position of transcendental subjectivity which haunts Being and Time. Heidegger did so in 1929/30 (...) by shattering the unity of Dasein's temporal horizon--a unity which still preserved the assumption of being as permanent presence. This enabled Heidegger to think through the turn or Kehre to the occurrence of being as difference as the originary event which gave rise not only to Greek philosophy but the Western tradition as a whole. ;It is precisely at this juncture that Holderlin's poetic thought and language became significant for Heidegger. The turn from the unity of Dasein's temporality to the occurrence of being as time implies not only a revolution in thinking but also a revolution in language. Heidegger's attempt to set this revolution in motion by setting the originary sense of the Greek logos to work linguistically in his own work is the philosophical counterpart of what Norbert von Hellingrath first described as Holderlin's harte Fugung or hard style. ;The pre-logical grammar and syntax Heidegger employed, I have called the language of revolution. Its purpose is to dislocate thinking out of metaphysics toward a hidden Greek origin in the past which shows itself in the future as what is left unthought of the Greek beginning and what still remains to be thought. This back-and-forth movement of questioning is the philosophical counterpart to Holderlin's poetic andenken. In dislocating political and ideological thought from its metaphysical foundations, Heidegger intended to shift the political revolution, especially in the universities, toward a second, deeper revolution which would confront the hidden origin of the Western tradition itself.
