When using precision grip to pick up objects, there are many possible pairs of grasp points that permit the thumb and index finger to exert opposed forces for secure grip. Previously, it was shown that individuals select grasp points so that the line between them (grasp axis) passes through or near the center of mass (CoM), thus minimizing the torque around the grasp axis during lifting. The accuracy of grasp axis selection depended on object spatial symmetry, indicating the importance of vision. The authors investigated how grasp point selection is influenced by haptic as well as visual information. Ten participants lifted cuboids whose CoM was located either symmetrically in the geometric center or asymmetrically toward one end. Results for the asymmetric cuboid revealed that grasp points migrated toward the asymmetric CoM from the geometric center. This was more pronounced in the presence of visual cues that reliably indicated the location of CoM. The results suggest that grasp point selection is influenced by a multimodal representation of CoM. 相似文献

A visual coincidence timing task was used to compare the level of performance (constant error) and the intra-individual variability of 100 normal and 100 educable mentally retarded children. The mean performance of the intellectually normal children on this task was significantly superior to that of the retarded children, and the intra-individual variability of the latter was significantly greater than that of the former. The hypothesis that high intra-individual variability and depressed level of performance are closely associated was not supported. 相似文献

According to the principle Grice calls ‘Modified Occam's Razor’ (MOR), ‘Senses are not to be multiplied beyond necessity’. More carefully, MOR says that if there are distinct ways in which an expression is regularly used, then, all other things being equal, we should favour the view that the expression is unambiguous and that certain uses of it can be explained in pragmatic terms. In this paper I argue that MOR cannot have the central role that is typically assigned to it by those who deploy it. More specifically, I argue that potential justifications of the epistemic import of parsimony in semantic theorizing are problematic, and that even if MOR could be justified, it has a redundant role to play in adjudicating the debate between the ambiguity-theorist and the proponent of the pragmatic approach. 相似文献

In this paper, I consider the validity and proper formulation of the only‐x‐and‐y principle, which states, roughly, that whether a later individual, y, is numerically identical to an earlier individual, x, can depend only on facts about x and y and the relationships between them. In the course of my investigation, I distinguish between two classes of physical entities?–?those that exist in a ‘real’ sense, and those that exist in a mere Cambridge sense. This distinction is grounded in Peter Geach's distinction between ‘real’ and mere Cambridge change. I argue in favor of a modified version of the only‐x‐and‐y principle?–?the qualified only‐x‐and‐y principle?–?which applies to entities that exist in a ‘real’ sense, but not to mere Cambridge entities. It is also argued that the plausibility of the qualified only‐x‐and‐y principle has more to do with facts about the nature of causality than with intuitions we have about existence or numerical identity. I finish by considering some traditional objections to the only‐x‐and‐y principle, and conclude that they do not succeed in refuting the qualified only‐x‐and‐y principle. 相似文献

This paper concerns the interpretation of iconography in the absence of any confirmatory textual explanation. Variations in iconographical representation are often considered as indicators of doctrinal variation rather than in the context of artistic style. This is particularly important when the icons examined are apparently of primary significance in the belief system under scrutiny. A detailed analysis of one specific example of Mithraic iconography reveals significant variations, both in location and in composition. Throughout the Roman Empire, significant differences have also occurred between examples found within the same regions, making the suggestion that iconographic variation equals theological variation difficult to sustain. In support of the work of E. Will, this paper suggests that regional artistic influences may have played a greater significance in the development of Mithraic icons than many present academics would allow. Further, this paper suggests that the evidence indicates that the Mithraic canon of iconographic representation was sufficiently flexible for the individualization of Mithraic monuments, and for elements of one scene to be ‘borrowed’ and incorporated into another. 相似文献

Given the large amount of information that we encounter, we often must prioritize what information we attempt to remember. Although critical for everyday functioning, relatively little research has focused on how people prioritize the encoding of information. Recent research has shown that people can and do selectively remember information assigned with higher, relative to lower, importance. However, the mechanisms underlying this prioritization process and the consequences of these processes are still not well understood. In the present study, we sought to better understand these prioritization processes and whether implementing these processes comes at the cost of memory accuracy, by increasing false memories. We used a modified form of the Deese/Roediger–McDermott (DRM) paradigm, in which participants studied DRM lists, with each list paired with low, medium, or high point values. In Experiment 1, encoding higher values led to more false memories than did encoding lower values, possibly because prioritizing information enhanced relational processing among high-value words. In Experiment 2, disrupting relational processing selectively reduced false memories for high-value words. Finally, in Experiment 3, facilitating relational processing selectively increased false memories for low-value words. These findings suggest that while prioritizing information can enhance true memory, this process concomitantly increases false memories. Furthermore, the mechanism underlying these prioritization processes depends on the ability to successfully engage in relational processing. Thus, how we prioritize the encoding of incoming information can come at a cost in terms of accurate memory. 相似文献

Attributes of words can be known even when the words are not currently retrievable. Although repeatedly demonstrated for semantic and contextual dimensions, the evidence is ambiguous for structural characteristics. The present research demonstrates significant above-chance first-letter knowledge across four ordinal levels of retrieval confidence for nonretrieved words—tip of the tongue (TOT), high familiar, low familiar, unfamiliar. Contrary to prior research, there was minimal evidence for syllable number knowledge, even at highest confidence levels. Initial letter recognition in the absence of retrieval resembles the recognition without identification in episodic memory (Cleary, Current Directions in Psychological Science 17: 353–357, 2008), and such implicit familiarity may contribute more generally to confidence assessments of word knowledge in both semantic and episodic memory domains. Furthermore, this outcome suggests that word feature priming in the form of partial phonological activation may occur to some extent for all words during a retrieval attempt, and even for ones that are judged to be unknown. 相似文献

Pediatric traumatic brain injury: Language outcomes and their relationship to the arcuate fasciculus
Frédérique J. Liégeois Kate Mahony Alan Connelly Lauren Pigdon Jacques-Donald Tournier Angela T. Morgan 《Brain and language》2013
Pediatric traumatic brain injury (TBI) may result in long-lasting language impairments alongside dysarthria, a motor-speech disorder. Whether this co-morbidity is due to the functional links between speech and language networks, or to widespread damage affecting both motor and language tracts, remains unknown. 相似文献
