The present study examined individual differences in the automaticity of visual word recognition. Specifically, we examined
whether people can recognize words while central attention is devoted to another task and how this ability depends on reading
skill. A lexical-decision Task 2 was combined with either an auditory or visual Task 1. Regardless of the Task 1 modality,
Task 2 word recognition proceeded in parallel with Task 1 central operations for individuals with high Nelson-Denny reading
scores, but not for individuals with low reading scores. We conclude that greater lexical skill leads to greater automaticity,
allowing better readers to more efficiently perform lexical processes in parallel with other attention-demanding tasks. 相似文献

Observers in this study judged which of two fields contained the greater number of spots. Spots had difference-of-Gaussian luminance profiles and could differ in contrast polarity or were of uniform luminance and could differ in size. Weber fractions for all observers except one varied little except when spots varied in size. It is suggested that the results of this and previous studies might be explained by the existence of neurons tuned for number. 相似文献

The present experiments examined the automaticity of word recognition. The authors examined whether people can recognize words while central attention is devoted to another task and how this ability changes across the life span. In Experiment 1, a lexical decision Task 2 was combined with either an auditory or a visual Task 1. Regardless of the Task 1 modality, Task 2 word recognition proceeded in parallel with Task 1 central operations for older adults but not for younger adults. This is a rare example of improved cognitive processing with advancing age. When Task 2 was nonlexical (Experiment 2), however, there was no evidence for greater parallel processing for older adults. Thus, the processing advantage appears to be restricted to lexical processes. The authors conclude that greater cumulative experience with lexical processing leads to greater automaticity, allowing older adults to more efficiently perform this stage in parallel with another task. 相似文献

Developmental dyscalculia (DD) is a pervasive difficulty affecting number processing and arithmetic. It is encountered in around 6% of school-aged children. While previous studies have mainly focused on general cognitive functions, the present paper aims to further investigate the hypothesis of a specific numerical deficit in dyscalculia. The performance of 10- and 11-year-old children with DD characterised by a weakness in arithmetic facts retrieval and age-matched control children was compared on various number comparison tasks. Participants were asked to compare a quantity presented in either a symbolic (Arabic numerals, number words, canonical dots patterns) or a nonsymbolic format (noncanonical dots patterns, and random sticks patterns) to the reference quantity 5. DD children showed a greater numerical distance effect than control children, irrespective of the number format. This favours a deficit in the specialised cognitive system underlying the processing of number magnitude in children with DD. Results are discussed in terms of access and representation deficit hypotheses. 相似文献

A large body of evidence indicates clear relationships between number and space processing in healthy and brain-damaged adults, as well as in children. The present paper addressed this issue regarding atypical math development. Adults with a diagnosis of dyscalculia (DYS) during childhood were compared to adults with average or high abilities in mathematics across two bisection tasks. Participants were presented with Arabic number triplets and had to judge either the number magnitude or the spatial location of the middle number relative to the two outer numbers. For the numerical judgment, adults with DYS were slower than both groups of control peers. They were also more strongly affected by the factors related to number magnitude such as the range of the triplets or the distance between the middle number and the real arithmetical mean. By contrast, adults with DYS were as accurate and fast as adults who never experienced math disability when they had to make a spatial judgment. Moreover, number–space congruency affected performance similarly in the three experimental groups. These findings support the hypothesis of a deficit of number magnitude representation in DYS with a relative preservation of some spatial mechanisms in DYS. Results are discussed in terms of direct and indirect number–space interactions. 相似文献

The paper argues that an assessment of individualism requires distinguishing five individualistic claims about the self and society: 1) Philosophical Individualism holds that individuals are distinct from society in their reality and capacity for knowledge; 2) The dignity of the individual is a moral belief about the status of human beings; 3) The ideal of individuality is a value belief about the value of diversity; 4) Moral individualism is a comprehensive moral theory based upon philosophical individualism; 5) Political liberalism is a theory of social justice based on construing human dignity in terms of equal liberty. It is argued that philosophical individualism should be rejected and, hence, moral individualism, that individuality is desirable but not obligatory, and that political liberalism, if it can avoid a tendency toward favoring individualistic conceptions of the good, is necessary for dignity in a modern society. 相似文献

My main aim in this paper is to clarify the concepts of referential success and of referential continuity that are so crucial
to the scientific realism debate. I start by considering the three dominant theories of reference and the intuitions that
motivate each of them. Since several intuitions cited in support of one theory conflict with intuitions cited in support of
another something has to give way. The traditional policy has been to reject all intuitions that clash with a chosen theory.
A more radical policy, tied to some experimental philosophers, has called for the rejection of any evidential role for intuitions.
I explore a largely ignored third alternative, i.e. saving intuitions (and their evidential role) even when they are at odds.
To accommodate conflicting intuitions different sets of internally consistent (yet externally inconsistent) intuitions are
taken to lend credence to different concepts of reference. In the current context, this means that the concepts of referential
success and referential continuity are not monolithic. They are what I call ‘polylithic’. This paper is as much about meta-philosophical
concerns with the role of intuitions as it is about reference and the scientific realism debate. Regarding the former I hope
that a blueprint will emerge for similar projects in other philosophical domains. Regarding the latter, I hope that polylithicity
helps disentangle claims about referential success and continuity in the scientific realism debate by making perspicuous which
concepts are best equipped to evaluate the realist’s epistemic claims against the historical record of science. 相似文献

The paper shows how we can add a truth predicate to arithmetic (or formalized syntactic theory), and keep the usual truth schema Tr(A)A (understood as the conjunction of Tr(A)A and ATr(A)). We also keep the full intersubstitutivity of Tr(A)) with A in all contexts, even inside of an . Keeping these things requires a weakening of classical logic; I suggest a logic based on the strong Kleene truth tables, but with as an additional connective, and where the effect of classical logic is preserved in the arithmetic or formal syntax itself. Section 1 is an introduction to the problem and some of the difficulties that must be faced, in particular as to the logic of the ; Section 2 gives a construction of an arithmetically standard model of a truth theory; Section 3 investigates the logical laws that result from this; and Section 4 provides some philosophical commentary. 相似文献

When people rapidly judge the truth of claims about the present or the past, a related but nonprobative photo can produce “truthiness,” an increase in the perceived truth of those claims (Newman, Garry, Bernstein, Kantner, & Lindsay, 2012). What we do not know is the extent to which nonprobative photos cause truthiness for the future. We addressed this issue in four experiments. In each experiment, people judged the truth of claims that the price of certain commodities (such as manganese) would increase (or decrease). Half of the time, subjects saw a photo of the commodity paired with the claim. Experiments 1A and 1B produced a “rosiness” bias: Photos led people to believe positive claims about the future but had very little effect on people’s belief in negative claims. In Experiment 2, rosiness occurred for both close and distant future claims. In Experiments 3A and 3B, we tested whether rosiness was tied to the perceived positivity of a claim. Finally, in Experiments 4A and 4B, we tested the rosiness hypothesis and found that rosiness was unique to claims about the future: When people made the same judgments about the past, photos produced the usual truthiness pattern for both positive and negative claims. Considered all together, our data fit with the idea that photos may operate as hypothesis-confirming evidence for people’s tendency to anticipate rosy future outcomes. 相似文献
