Ramscar and colleagues (2010, this volume) describe the "feature-label-order" (FLO) effect on category learning and characterize it as a constraint on symbolic learning. I argue that FLO is neither a constraint on symbolic learning in the sense of "learning elements of a symbol system" (instead, it is an effect on nonsymbolic, association learning) nor is it, more than any other constraint on category learning, a constraint on symbolic learning in the sense of "solving the symbol grounding problem." 相似文献

The multimillennial philosophical discussion about life after death has received a recent boost in the prospect of immortality attained via technologies. In this newer version, humans generally are considered mortal but may develop means of making themselves immortal. If “immortal” means not mortal, thus existing for infinity, and if the proposed infinite‐existing entity is material, it must inhabit an infinite material universe. If the proposed entity is not material, there must be means by which it can shed its material substance and exist nonmaterially. The article examines arguments for how an infinite life would be possible given current physical understanding. The paper considers a Pascalian‐style wager weighing the likelihood of adjusting to existence wholly within a finite universe versus betting on there being some way to construe the universe(s) as a viable medium for infinite beings. Conclusion: the case for a finite being to exist infinitely has little viable support. 相似文献

We have developed a process model that learns in multiple ways while finding faults in a simple control panel device. The model predicts human participants' learning through its own learning. The model's performance was systematically compared to human learning data, including the time course and specific sequence of learned behaviors. These comparisons show that the model accounts very well for measures such as problem-solving strategy, the relative difficulty of faults, and average fault-finding time. More important, because the model learns and transfers its learning across problems, it also accounts for the faster problem-solving times due to learning when examined across participants, across faults, and across the series of 20 trials on an individual participant basis. The model shows how learning while problem solving can lead to more recognition-based performance, and helps explain how the shape of the learning curve can arise through learning and be modified by differential transfer. Overall, the quality of the correspondence appears to have arisen from procedural, declarative, and episodic learning all taking place within individual problem-solving episodes. 相似文献

The author explores ideas surrounding immortality and death focusing on the interplay between their development in two stories by Borges ('The circular ruins' and 'The immortal') and their manifestation in a patient. With the help of Borges's stories, the author addresses the desperate necessity experienced by some individuals to search for immortality. This is not just an expression of the universal wish to live forever but, at a deeper level, arises from the impossibility of bearing the mental pain of experiencing ordinary human vulnerability and loss - death being the ultimate expression of such vulnerability. It is suggested that the relentless pursuit of immortality in such individuals expresses an omnipotent phantasy of ridding the self of the emotional pain and fear that arises through being alive. It leads to a denial of the emotional significance of passage of time, of separation and sexual differences. In actuality, the individual's state of not feeling approximates to a complete loss of human identity and emotional death, with no place for any meaningful others. The individual him/herself becomes a 'mere image', living in a delusional world peopled by him/herself and his/ her projections, and ending up trapped inside the circular ruins he/she has generated. The horror experienced at the stark awareness of the individual's emotional death and the wish to re-establish contact with the good internal objects that have been attacked sets in motion the long process of searching for the recovery of a sense of temporality (that would still include the wish for immortality) and, with it, a sense of identity. 相似文献

Within Piaget there is an implicit theory of the development of explicit memory. It rests in the dynamical trajectory underlying
the development of causality, object, space and time – a complex (COST) supporting a symbolic relationship integral to the
explicit. Cassirer noted the same dependency in the phenomena of aphasias, insisting that a symbolic function is being undermined
in these deficits. This is particularly critical given the reassessment of Piaget’s stages as the natural bifurcations of
a self-organizing dynamic system. The elements of a theoretical framework required to support explicit memory are developed,
to include, (1) the complex developmental trajectory supporting the emergence of the explicit in Piaget, (2) the concrete
dynamical system and the concept of a non-differentiable time contained in Bergson’s theory required to support a conscious,
as opposed to an implicit remembrance, (3) the relation to current theories of amnesia, difficulties posed by certain retrograde
amnesic phenomena, the role of the hippocampus and limitations of connectionist models, (4) the fact that nowhere in this
overall framework does the loss of explicit memory imply or require the destruction of experience “stored in the brain.” 相似文献

This set of studies tests the link between infra-humanization, symbolic threat, and discrimination within normative contexts. In two experiments, manipulating the degree of humanity of a disliked outgroup has an effect upon the discrimination towards it. The infra-humanized outgroup is more discriminated than the humanized one. Also, the perception of symbolic threat plays the role of a justifying factor for discrimination, and mediates the relationship between degrees of humanity and discrimination. Study 2 further shows that this mediation occurs only when an egalitarian norm is activated, and not when meritocracy is made salient. The discussion focuses on factors likely to prevent infra-humanization of outgroups. It also considers how norms may change the role of threat. 相似文献

Deficits in basic numerical processing have been identified as a central and potentially causal problem in developmental dyscalculia; however, so far not much is known about the typical and atypical development of such skills. This study assessed basic number skills cross-sectionally in 262 typically developing and 51 dyscalculic children in Grades 2, 3, and 4. Findings indicate that the efficiency of number processing improves over time and that dyscalculic children are generally less efficient than children with typical development. For children with typical arithmetic development, robust effects of numerical distance, size congruity, and compatibility of ten and unit digits in two-digit numbers could be identified as early as the end of Grade 2. Only the distance effect for comparing symbolic representations of numerosities changed developmentally. Dyscalculic children did not show a size congruity effect but showed a more marked compatibility effect for two-digit numbers. We did not find strong evidence that dyscalculic children process numbers qualitatively differently from children with typical arithmetic development. 相似文献

People who score high on modern racism scales consistently oppose reparations for race-based social injustices. Scholars debate whether this opposition reflects racism [e.g., Sears, D. O., & Henry, P. J. (2005). Over thirty years later: A contemporary look at symbolic racism. In M.P Zanna, (Ed.), Advances in experimental social psychology, Vol. 37 (pp. 95-150). San Diego, CA: Elsevier Academic Press] or a principled conservative ideology [e.g., Sniderman, P. M., & Tetlock, P. E. (1986). Symbolic racism: Problems of motive attribution in political analysis. Journal of Social Issues, 42, 129-150]. We tested these competing hypotheses by examining support for government reparations for adult survivors of childhood abuse. We manipulated whether the survivors were of European or Aboriginal heritage. Consistent with a racism hypothesis, high modern racists indicated less support for reparations when the survivors were of Aboriginal heritage than when the survivors were of European heritage. Interestingly, low modern racists supported reparations more for Aboriginal Canadian than European Canadian survivors. We discuss three explanations of the responses of low modern racists. 相似文献

The main goal of this study was to examine the relationship between different types of extrinsic motivation for religious
behaviors as conceptualised within self-determination theory (Ryan & Deci, 2000) and Wulff's (1991) framework of literal versus symbolic approaches of religious contents. Results from a Belgian sample
of active believers (N=186) show that the internalization of one's reasons for performing religious behaviors was positively associated with an
open, symbolic interpretation of religious belief contents and a stronger adherence to Christian beliefs. Moreover, internalization
was also positively related to general well-being and frequency of prayer but unrelated to church attendance. It is concluded
that individuals who engage in religious behaviors because of its perceived personal significance will show more cognitive
flexibility and open-mindedness towards Christian belief contents, a stronger adherence to this message, higher well-being
and more frequent engagement in specific religious behaviors.

Plausibility has been implicated as playing a critical role in many cognitive phenomena from comprehension to problem solving. Yet, across cognitive science, plausibility is usually treated as an operationalized variable or metric rather than being explained or studied in itself. This article describes a new cognitive model of plausibility, the Plausibility Analysis Model (PAM), which is aimed at modeling human plausibility judgment. This model uses commonsense knowledge of concept-coherence to determine the degree of plausibility of a target scenario. In essence, a highly plausible scenario is one that fits prior knowledge well: with many different sources of corroboration, without complexity of explanation, and with minimal conjecture. A detailed simulation of empirical plausibility findings is reported, which shows a close correspondence between the model and human judgments. In addition, a sensitivity analysis demonstrates that PAM is robust in its operations. 相似文献
