What is the revised Fear Survey Schedule for Children measuring?

This study was designed to investigate parameters of children's fear in terms of frequency of fearful thoughts and avoidance behaviour. It is suggested that current measures such as the Fear Survey Schedule for Children--Revised (FSSC-R) do not assess fearful behaviour in the sense of the occurrence of fearful responding in daily life, but rather reflect a negative affective response to the thought of occurrence of specific events. A modified version of the FSSC-R examined the frequency of fearful thoughts/feelings and avoidance activities amongst 376 children aged 7-12 yr. Contrary to predictions, it was found that children reported high levels of fearful thoughts and avoidance behaviour to those items identified as the greatest fears on the FSSC-R, namely fears of injury, illness, death and danger. These events were typically of low probability (e.g. earthquakes) and the question was raised as to what children are responding to when they are asked to rate their fearful responses. The same pattern of results was reflected in older compared to younger children. It is suggested that even when children are asked to rate frequency of fearful thoughts or avoidance behaviour, they tend to respond to fear questionnaire items according to their affective response to the image or thought of the stimulus situation rather than their actual fear responses. Both the FSSC-R and the modified version were found to discriminate between teacher nominated high and low fearful children and to correlate significantly with a self report measure of anxiety.     

What is consciousness for?

The answer to the title question is, in a word, volition. Our hypothesis is that the ultimate adaptive function of consciousness is to make volitional movement possible. All conscious processes exist to subserve that ultimate function. Thus, we believe that all conscious organisms possess at least some volitional capability. Consciousness makes volitional attention possible; volitional attention, in turn, makes volitional movement possible. There is, as far as we know, no valid theoretical argument or convincing empirical evidence that consciousness itself has any direct causal efficacy other than volition. Consciousness, via volitional action, increases the likelihood that an organism will direct its attention, and ultimately its movements, to whatever is most important for its survival and reproduction.     

What is the future for tool-specific generalized motor programs?

A key issue in cognitive sciences is to understand the cognitive bases of human tool use. Answers have been provided by two competing approaches. The manipulation-based approach assumes that humans can use tools because of the ability to store sensorimotor knowledge about how to manipulate tools. By contrast, for the reasoning-based approach, human tool use is based on the ability to reason about physical object properties. Recently, Caruana and Cuccio proposed a kind of reconciliation, based on the distinction between three types of abductive inference, involving a different contribution of motor and cognitive elements: Automatic abduction (motor + and cognitive-), abduction by selection (motor ± and cognitive±) and creative abduction (motor- and cognitive+). This perspective offers new interesting avenues. Nevertheless, it is also subject to several theoretical and epistemological limitations, which make it in its present form inappropriate for the study of the cognitive bases of human tool use. This article aims to discuss these limitations.     

What is the Grounding Problem?

A philosophical standard in the debates concerning material constitution is the case of a statue and a lump of clay, Lumpl and Goliath respectively. According to the story, Lumpl and Goliath are coincident throughout their respective careers. Monists hold that they are identical; pluralists that they are distinct. This paper is concerned with a particular objection to pluralism, the Grounding Problem. The objection is roughly that the pluralist faces a legitimate explanatory demand to explain various differences she alleges between Lumpl and Goliath, but that the pluralist’s theory lacks the resources to give any such explanation. In this paper, I explore the question of whether there really is any problem of this sort. I argue (i) that explanatory demands that are clearly legitimate are easy for the pluralist to meet; (ii) that even in cases of explanatory demands whose legitimacy is questionable the pluralist has some overlooked resources; and (iii) there is some reason for optimism about the pluralist’s prospects for meeting every legitimate explanatory demand. In short, no clearly adequate statement of a Grounding Problem is extant, and there is some reason to believe that the pluralist can overcome any Grounding Problem that we haven’t thought of yet.     

What is the diplopia threshold?

The magnitude and nature of the diplopia threshold, that is, the value of the retinal disparity at which binocular single vision ends, were studied in four experiments. The results show that the magnitude of the diplopia threshold is highly dependent on the subject tested (differences up to a factor of 6), the amount of training the subject has received (differences up to a factor of 2.5), the criterion used for diplopia (limits for unequivocal singleness of vision were up to a factor of 3 lower than those for unequivocal doubleness of vision), and the conspicuousness of disparity that can be influenced both by the surrounding stimuli (differences up to a factor of 3.5) and stereoscopic depth (differences up to a factor of 4.5). Our data do not confirm previous findings of interference effects associated with the initial appearance of binocular disparity when test stimuli are presented tachistoscopically. A remarkable finding was that the magnitude of the diplopia threshold seems to be determined by the amount of intrinsic noise in the disparity domain, as revealed by the standard deviations of the thresholds for tachistoscopically presented test stimuli. The overall results suggest that the diplopia threshold is, in essence, not the rigid boundary of a dead zone, but, rather, a disparity level corresponding to a lenient criterion for singleness of vision which leads touseful interpretation of the percept of the stimulus without disparity, given the variability of this percept due to intrinsic noise in the disparity domain.     

What is the axiomatic method?

The modern notion of the axiomatic method developed as a part of the conceptualization of mathematics starting in the nineteenth century. The basic idea of the method is the capture of a class of structures as the models of an axiomatic system. The mathematical study of such classes of structures is not exhausted by the derivation of theorems from the axioms but includes normally the metatheory of the axiom system. This conception of axiomatization satisfies the crucial requirement that the derivation of theorems from axioms does not produce new information in the usual sense of the term called depth information. It can produce new information in a different sense of information called surface information. It is argued in this paper that the derivation should be based on a model-theoretical relation of logical consequence rather than derivability by means of mechanical (recursive) rules. Likewise completeness must be understood by reference to a model-theoretical consequence relation. A correctly understood notion of axiomatization does not apply to purely logical theories. In the latter the only relevant kind of axiomatization amounts to recursive enumeration of logical truths. First-order “axiomatic” set theories are not genuine axiomatizations. The main reason is that their models are structures of particulars, not of sets. Axiomatization cannot usually be motivated epistemologically, but it is related to the idea of explanation.     

What is the Accordion Effect?

In "Action and Responsibility,' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.' Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his critique, in his "Causing Voluntary Actions,' of a much discussed view of H. L. A. Hart and A. M. Honoré that Feinberg labels the "voluntary intervention principle.' In this essay I reflect on what the accordion effect is supposed by Feinberg to be, on differences between Feinberg's understanding of this idea and that of Donald Davidson, and on the interaction between Feinberg's discussion of the accordion effect and his critique of the voluntary intervention principle.     

What is the Problem of Non-Existence?

It is widely held that there is a problem of talking about or otherwise representing things that not exist. But what exactly is this problem? This paper presents a formulation of the problem in terms of the conflict between the fact that there are truths about non-existent things and the fact that truths must be answerable to reality, how things are. Given this, the problem of singular negative existential statements is no longer the central or most difficult aspect of the problem of non-existence, despite what some philosophers say.

What Exactly is the Explanatory Gap?

It is widely agreed among contemporary philosophers of mind that science leaves us with an ‘explanatory gap’—that even after we know everything that science can tell us about the conscious mind and the brain, their relationship still remains mysterious. I argue that this agreed view is quite mistaken. The feeling of a ‘explanatory gap’ arises only because we cannot stop ourselves thinking about the mind–brain relation in a dualist way.     

What is the Point of Sufficiency?

Telic sufficientarians hold that there is something special about a certain threshold level such that benefiting people below it, or raising them above it, makes an outcome better in at least one respect. The article investigates what fundamental value might ground that view. The aim is to demonstrate that sufficientarianism, at least on this telic version, is groundless and as such indefensible. The argument is advanced in three steps: first, it is shown that sufficientarianism cannot be grounded in a personal value. Neither, secondly, is it committed to the person‐affecting view, the view that says that nothing can be better (worse) if there is no one for whom it is better (worse). This, in itself, is of interest because some sufficientarians reject egalitarianism precisely for its alleged incompatibility with the person‐affecting view. Sufficientarians' disavowal of the person‐affecting view implies that their view, similarly to egalitarianism (and, perhaps less famously, prioritarianism), must be anchored in some impersonal value. But crucially, and this is the third step of the argument, there is no apparent value that can fit that role. We must conclude, then, that telic sufficientarianism is groundless.     

What is the Normativity of Meaning?

There has been much debate over whether to accept the claim that meaning is normative. One obstacle to making progress in that debate is that it is not always clear what the claim amounts to. In this paper, I try to resolve a dispute between those who advance the claim concerning how it should be understood. More specifically, I critically examine two competing conceptions of the normativity of meaning, rejecting one and defending the other. Though the paper aims to settle a dispute among proponents of the claim that meaning is normative, it should be of interest to those who challenge it. After all, before one takes aim, one’s target needs to be in clear view.
