What is special about indexical attitudes?

In this paper, I assess whether indexical attitudes, e.g. beliefs and desires, have any special properties or present any special challenge to theories of propositional attitudes. I being by investigating the claim that allegedly problematic indexical cases are just instances of the familiar phenomenon of referential opacity. Regardless of endorsing that claim, I provide an argument to the effect that indexical attitudes do have a special property. My argument relies on the fact that one cannot account for what is it to share someone else’s indexical attitudes without rejecting some plausible thesis about propositional attitudes. In the end, I assess Herman Cappelen and Josh Dever’s considerations on intentional action and extract an argument from them that could – if successful – neutralize my own. I finish by arguing that their argument has an important flaw, thus failing to convince us that indexical attitudes are just as ordinary as any other.     

What is Christian about Christian bioethics?

What is Christian about Christian bioethics? The short answer to this question is that the Incarnation should shape the form and content of Christian bioethics. In explicating this answer it is argued that contemporary medicine is unwittingly embracing and implementing the transhumanist dream of transforming humans into posthumans. Contemporary medicine does not admit that there are any limits in principle to the extent to which it should intervene to improve the quality of human life. This largely inarticulate, yet ambitious, agenda is derived first in late modernity's failed, but nonetheless ongoing, attempt to transform necessity into goodness, and second the loss of any viable concept of eternity, thereby stripping temporal existence of any normative significance. In short, medicine has become the vanguard of a profane attempt to save humankind by extracting data from flesh. In response, it is contended that an alternative Christian bioethics must be shaped by the Incarnation, the Word made flesh. This assertion does not entitle Christians to oppose the posthuman trajectory of contemporary medicine on the basis of any natural or biological essentialism. Rather, it is an evangelical witness to the grace of Christ's redemption instead of the work of self-transformation. It is Christ alone who thereby makes the vulnerability and mortality of finitude a gift and blessing. Specifically, it is maintained that the chasm separating necessity and goodness cannot be filled but only bridged through the suffering entailed in Christ's cross, and through Christ's resurrection eternity becomes the standard against which the temporal lives of human creatures are properly formed and measured. Consequently, Christian bioethics should help us become conformed to Christ rather than enabling self-transformation.     

What is minimal about predictive inferences?

Pronunciation of a probe word that relates to a highly predictable event is typically facilitated when the probe immediately follows the target sentence, but not when it is delayed until after a second sentence. These findings suggest that inferences about highly predictable events are minimally drawn during reading. Using a similar paradigm, in which the probe was delayed, we found significant priming in a reading condition that encouraged focus on the referential state of affairs (situation level) expressed in the sentences. In contrast, significant priming forpredictive texts was not observed in a reading condition that encouraged focus on the text per se (text level). These results are interpreted within a theoretical model that assumes that predictive inferences are represented at a situational level only, whereas explicitly presented information is represented at several levels (text and situational). It is in this sense that predictive inferences may be said to be minimally represented.     

What is implicit about implicit self-esteem?

Modern advances in implicit social cognition enabled development of novel methods for examining less conscious aspects of self-worth. The use of such “implicit” measures of self-esteem is based on the premise that because they circumvent direct self-reports, they must capture more implicit, automatic components of self-evaluation. Whether self-evaluations captured via “implicit” measures actually have these functional properties requires empirical verification, however. This investigation critically examined the evidence for such assumptions regarding the Name-Letter Test, one of the most popular implicit measures, by adopting a phenomenological approach. The results revealed that many respondents were aware of the self-relevant nature of the measure at the time of assessment. Moreover, at least some variance in the “implicit” measurement outcomes was accounted for by relevant conscious beliefs, particularly among those aware of the self-relevant nature of the task. The implications for understanding the nature and assessment of unconscious self-worth are discussed.     

What is so special about embodied simulation?

Simulation theories of social cognition abound in the literature, but it is often unclear what simulation means and how it works. The discovery of mirror neurons, responding both to action execution and observation, suggested an embodied approach to mental simulation. Over the past few years this approach has been hotly debated and alternative accounts have been proposed. We discuss these accounts and argue that they fail to capture the uniqueness of embodied simulation (ES). ES theory provides a unitary account of basic social cognition, demonstrating that people reuse their own mental states or processes represented with a bodily format in functionally attributing them to others.     

What is so Good about Moral Freedom?

Many Christian philosophers believe that it is a great good that human beings are free to choose between good and evil, so good indeed that God is justified in putting up with a great many evil choices for the sake of it. But many of the same Christian philosophers also believe that God is essentially good – good in every possible world. Unlike his sinful human creatures, God cannot choose between good and evil. In that sense, he is not 'morallyFree'. It is not easy to see how to fit these two theses into a single coherent package. If moral freedom is such a great good in human beings, why is it not a grave defect in God that he lacks it? And if the lack of moral freedom does not detract in any way from God's greatness, would it not have been better for us not to have it? I develop, but ultimately reject, what I take to be the most initially promising strategy for resolving this dilemma.     

What does distractibility in ADHD reveal about mechanisms for top-down attentional control?

In this study, we attempted to clarify whether distractibility in ADHD might arise from increased sensory-driven interference or from inefficient top-down control. We employed an attentional filtering paradigm in which discrimination difficulty and distractor salience (amount of image “graying”) were parametrically manipulated. Increased discrimination difficulty should add to the load of top-down processes, whereas increased distractor salience should produce stronger sensory interference. We found an unexpected interaction of discrimination difficulty and distractor salience. For difficult discriminations, ADHD children filtered distractors as efficiently as healthy children and adults; as expected, all three groups were slower to respond with high vs. low salience distractors. In contrast, for easy discriminations, robust between-group differences emerged: ADHD children were much slower and made more errors than either healthy children or adults. For easy discriminations, healthy children and adults filtered out high salience distractors as easily as low salience distractors, but ADHD children were slower to respond on trials with low salience distractors than they did on trials with high salience distractors. These initial results from a small sample of ADHD children have implications for models of attentional control, and ways in which it can malfunction. The fact that ADHD children exhibited efficient attentional filtering when task demands were high, but showed deficient and atypical distractor filtering under low task demands suggests that attention deficits in ADHD may stem from a failure to efficiently engage top-down control rather than an inability to implement filtering in sensory processing regions.     

What is Philosophical about Kant’s Anthropology?

Abstract

In this essay, I argue that Kant’s Anthropology from a Pragmatic Point of View is fundamentally about the sphere of civilization, and, with this, a particular kind of philosophical self-understanding. By civilization, Kant means to indicate the process by which human beings transform their inner natures based on pragmatic or prudential considerations born of our living together. Civilization is what we do to ourselves in order to get along with others with whom we share the earth. In the Anthropology, what we come to understand about ourselves is the possibility of transforming our inner natures based on our will.     

What is magic about the magical number four?

Summary Previous studies have shown that the apprehension of number can be represented by three models according to the experimental procedure and the data analysis. The present experiment was designed to test the effect of figural characteristics of pattern on the response time. The subjects were asked to perform a same/different judgment, i.e., they were requested to decide whether a dot pattern, shown on a monitor, equalled a previously defined target number (n=2–6) or not. Different types of pattern were used and learning effects were studied. As was expected, the slopes for random and linear patterns were not so steep when the target number was low. With patterns in the dice mode, however, the slope was zero. Repeated presentations led to a slight reduction in slope for random and linear patterns only. In the case of the patterns in the dice mode, the repeated presentations caused only a change in the absolute reaction times (RTs) but had no effect on the slope. When the target numbers were larger (n=5–6), the repeated presentations led to remarkable reductions in slope for random and linear patterns. The slope discontinuity at n=4 occurred with all types of pattern but it became less pronounced in the course of training at least in the case of random and linear patterns. This result is explained by clustering effects, use of figural cues, and a more efficient scanning process.     

What is spiritual? What is spiritual suffering?

The author offers definitions for "spiritual" and for "spiritual suffering," suggesting that human spiritual needs include Love, Faith, Hope, Virtue, and Beauty. Spiritual suffering is experienced when these needs are unfulfilled. Spiritual care involves assisting in the fulfillment of these needs. He considers the constant movement between spiritual needs and fulfillments, encouraging use of fluid (not static) assessment methods using "spiritual spectra." As a model, this outline of basic spiritual needs may serve as the foundation for many current spiritual assessment tools.     

What is typical about the typicality effect in category-based induction?

Research on category-based induction has documented a consistent typicality effect: Typical exemplars promote stronger inferences about their broader category than atypical exemplars. This work has been largely confined to categories whose central tendencies are also the most typical members of the category. Does the typicality effect apply to the broad set of categories for which the ideal category member is considered most typical? In experiments with natural and artificial categories, typicality and induction-strength ratings were obtained for ideal and central-tendency exemplars. Induction strength was greatest for the central-tendency exemplars, regardless of whether the central tendency or the ideal was rated more typical. These results suggest that the so-called “typicality” effect is a special case of a more universal central-tendency effect in category-based induction.     

What is a fourdimensionalist to do about temporally extended properties?

Some properties and relations take time to be instantiated. They are not instantiated at a time, but through a temporal interval. Cognitive properties and relations such as understanding and thinking are like this, but also many biological, chemical, and microphysical properties and relations such as absorbing, freezing, radiating, and decaying. In this paper, I make a case for taking seriously such temporally extended properties (TEPs). I argue that they are ubiquitous and that our current theories of persistence would do well to make room for them in their ontology. The focus here is on fourdimensionalism and different ways it can accommodate TEPs. I explore four different ways of dealing with TEPs within a fourdimensionalist framework. These are: (a) to make the objects that bear apparent TEPs temporally more extended or “chunky,” while giving TEPs a reductive or eliminativist treatment in favor of instantaneous properties (IPs); (b) to make a series of objects the bearer of TEP predicates, while, again, holding only to IPs; (c) to endorse TEPs in their own right and take them to be temporally extended in a literal sense; and (d) to hold on to TEPs as atemporal properties and make the exemplification relation temporally extended. I discuss each of these options and highlight the types of problems that a fourdimensionalist faces in attempting to accommodate TEPs. I conclude that fourdimensionalists do not yet have a satisfactory account of TEPs in their hands.     

What is learned about nontarget items in simple visual search?

Human sensitivity to correlational structure between nontargets and likelihood of target presence in a visual letter-search task were studied in two experiments. In each of these experiments, the performance of subjects for whom the nontarget information was altered in the final trial block was compared with the performance of subjects for whom the nontarget information did not change. When stimulus strings were presented individually on a computer screen and subjects were required to make a yes-no decision about target presence (Experiment 1), the change in nontarget structure resulted in increased reaction times for target-absent trials. When subjects searched simultaneously for three possible targets (Experiment 2), the change in nontarget structure produced increased error rates and increased reaction times for both target-absent and target-present trials. Correlations between the amount of predictive information in individual stimulus strings and reaction times also showed that both switching and nonswitching subjects were sensitive to the nontarget context. However, neither self-reports of strategy nor postexperiment choices between context-consistent and -inconsistent letter strings indicated any explicit knowledge of the predictive information in the nontarget stimuli. Subjects can thus acquire and benefit from, apparently without awareness, information about subtle correlational structure in nontarget elements in simple visual search.
