Vagueness and Context

A number of recent accounts for vague terms postulate a kind of context-sensitivity, one that kicks in after the usual ‘external’ contextual factors like comparison class are established and held fixed. In a recent paper, ‘Vagueness without Context Change’(Mind 116 (2007): 275–92), Rosanna Keefe criticizes all such accounts. The arguments are variations on considerations that have been brought against context-sensitive accounts of knowledge, predicates of personal taste, epistemic modals, and the like. The issues are well known and there are variety of options available in reply. More important, the arguments rely on an overly narrow conception of context-sensitivity, suggesting that one size fits all. If Keefe’s arguments were cogent, they would tell against the context-sensitivity of just about any expression, beyond the typical indexicals, including the variation of vague terms with comparison class. However, the criticisms raised by Keefe do highlight certain questions that must be answered by an advocate of a context-sensitive account of vagueness, essentially the same sorts of questions that must be answered by a contextualist or relativist about knowledge, epistemic modals, predicates of personal taste, etc. The main purpose of this paper is to use replies to the relevant objections raised by Keefe as a springboard for further articulation of the underlying view of vagueness.     

Theorizing about the epistemic

I argue that epistemologists’ use of the term ‘epistemic’ has led to serious confusion in the discussion of epistemological issues. The source of the problem is that ‘epistemic’ functions largely as an undefined technical term. I show how this confusion has infected discussions of the nature of epistemic justification, epistemic norms for evidence gathering, and knowledge norms for assertion and belief.

Starting slow: the effects of response-switching frequency on patterns of cardiovascular reactivity

Research findings suggest that switching between competing response sets can be resource demanding. The current study focused on concurrent health-relevant physiological effects of task switching by assessing cardiovascular response at varying levels of switch frequency. The participants performed a response-switching task at three different levels of response set switching frequency (low, medium and high) while measurements of blood pressure and heart rate were taken. One group was exposed to response-switching frequency conditions in the order low → medium → high, while the other group was exposed to the same task conditions in the reverse order (i.e. high → medium → low). The results showed that the participants in the low → medium → high switch frequency group recovered faster from initially heightened systolic blood pressure when compared with participants in the high → medium → low group. It is concluded that the results point to a physiological "carry over" effect associated with beginning a task at rapid response switching frequency levels, and suggest the importance of habituation to task demands as a means of offsetting potentially unhealthy levels of reactivity. Implications for modern work environments are discussed.     

What's wrong with chemoprevention of prostate cancer?

When prostate-specific antigen (PSA) testing was introduced, proponents expected it to cut prostate-cancer mortality and did not expect it to unleash an epidemic of unnecessary treatments. Now that evidence of a mortality benefit remains unclear while evidence of overtreatment in undeniable, there is understandable interest in reducing the human costs of the PSA system. Two related drugs, finasteride and dutasteride, both proven to reduce the incidence of prostate cancer and the "risk of diagnosis," are being promoted accordingly. However, if not for the flaws of the PSA system the use of these drugs for purposes of prevention would lose its rationale. Not only are the drugs in this sense dependent on a faulty system, but their own mortality benefits are as speculative as PSA's-in addition to which, they introduce new risks.     

Conscientiousness and Agreeableness as Moderators of the Relationship Between Neuroticism and Counterproductive Work Behaviors: A constructive replication

Several previous studies examining the predictors of counterproductive work behaviors (CWBs) have found positive relationships for neuroticism and negative relationships for conscientiousness and agreeableness. We extend this research by examining whether employee personality traits interact with each other to influence CWBs. Because conscientiousness and agreeableness may suppress one's tendency to engage in CWBs, we hypothesized that the neuroticism–CWB relationship will be weaker among workers who are high in either conscientiousness or agreeableness than among workers who are low in these traits. Data from three independent samples provide support for these hypothesized moderator effects.     

Making tools isn't child's play

Tool making evidences intelligent, flexible thinking. In Experiment 1, we confirmed that 4- to 7-year-olds chose a hook tool to retrieve a bucket from a tube. In Experiment 2, 3- to 5-year-olds consistently failed to innovate a simple hook tool. Eight-year-olds performed at mature levels. In contrast, making a tool following demonstration was easy for even the youngest children. In Experiment 3, children’s performance did not improve given the opportunity to manipulate the objects in a warm-up phase. Children’s tool innovation lags substantially behind their ability to learn how to make tools by observing others.
