In their initial study of the development of children's spatial concepts, Piaget and Inhelder (1956) designed the “water-level”
and “plumb-line” tasks to assess children's Euclidean abilities to perceive and represent horizontals and verticals. Surprisingly,
subsequent research has shown that many adults perform badly on these tasks designed for children. Here we studied whether
adults (N=160) would also have difficulty on a shadow projection task developed to assess theoretically related projective spatial
concepts. The data showed that some adults had difficulty on the shadow task, whether tested by a drawing or by a selection
task, and whether scored with respect to qualitative shape or metric accuracy. Performance was significantly worse on complex
than simple forms, and when sex differences emerged, they favored males. As hypothesized, the best predictor of shadow performance
was performance on the Euclidean tasks. Scores on the Embedded Figures Test and participant sex accounted for small (but significant)
additional variance on shadow performance. Implications for theories of spatial development and for modeling individual differences
in spatial cognition are discussed. 相似文献

Faces convey distinct types of information: features and their spatial relations, which are differentially vulnerable to inversion. While inversion largely disrupts the processing of vertical spatial relations (e.g. eyes’ height), its effect is moderate for horizontal relations (e.g. interocular distance) and local feature properties. The SF ranges optimally transmitting horizontal and vertical face relations were here investigated to further address their functional role in face perception. Participants matched upright and inverted pairs of faces that differed at the level of local featural properties, horizontal relations in vertical relations. Irrespective of SF, the inversion effect was larger for vertical than horizontal and featural cues. Most interestingly, SF differentially influenced the processing of vertical, horizontal and featural cues in upright faces. Vertical relations were optimally processed in intermediate SF, which are known to carry useful information for face individuation. In contrast, horizontal relations were best conveyed by high SF, which are involved in the processing of local face properties. These findings not only confirm that horizontal and vertical relations play distinct functional roles in face perception, but they also further suggest a unique role of vertical relations in face individuation. 相似文献

This research examined the influence of cue temporal predictability on inhibition of return (IOR). In exogenous attention experiments, the cue that summons attention is non-informative as to where the target will appear. However, it is predictive as to when it will appear. Because in most experiments there are equal numbers of trials for each cue-target interval (SOA--stimulus onset asynchrony), as time passes from the appearance of the cue, the probability of target presentation increases. Predictability was manipulated by using three SOA distributions: non-aging, aging and accelerated-aging. A robust IOR was found that was not modulated by temporal information within a trial. These results show that reflexive effects are relatively protected against modulation by higher volitional processes. 相似文献

Research concerning the spatial dimension fit (tight versus loose) has been based on a tacit but untested assumption that the dimension fit is symmetrical, with tight- and loose-fitting relations highlighting the dimension fit with equal force. We propose a reformulation, documenting that adult speakers of English (Experiment 1) and Korean (Experiment 2) are sensitive to the dimension fit, but that their representation is asymmetric, with tight-fitting events highlighting fit with greater force than loose-fitting events. We propose that sensitivity to the dimension fit is more resilient than has previously been suggested, and that the asymmetry documented here provides a foundation upon which to pursue nuanced questions about the relationship between language and our underlying representations of space. 相似文献

The SNARC effect does not imply a mental number line 总被引:1,自引:0,他引:1
In this study, we directly contrast two approaches that have been proposed to explain the SNARC effect. The traditional direct mapping account suggests that a direct association exists between the position of a number on the mental number line and the location of the response. On the other hand, accounts are considered that propose an intermediate step in which numbers are categorized as either small or large between the number magnitude and the response representations. In a magnitude comparison task, we departed from the usual bimanual left/right response dimension and instead introduced the unimanual close/far dimension. A spatial-numerical association was observed: small numbers were associated with a close response, while large numbers were associated with a far response, regardless of the movement direction (left/right). We discuss why these results cannot be explained by assuming a direct mapping from the representation of numbers on a mental number line to response locations and discuss how the results can be explained by the alternative accounts. 相似文献

Kantian non-conceptualism 总被引:1,自引:0,他引:1
Robert Hanna 《Philosophical Studies》2008,137(1):41-64
There are perceptual states whose representational content cannot even in principle be conceptual. If that claim is true,
then at least some perceptual states have content whose semantic structure and psychological function are essentially distinct
from the structure and function of conceptual content. Furthermore the intrinsically “orientable” spatial character of essentially
non-conceptual content entails not only that all perceptual states contain non-conceptual content in this essentially distinct sense, but also that consciousness goes all the way down into so-called unconscious or subpersonal mental states. Both my argument for the existence of essentially non-conceptual
content and my theory of its structure and function have a Kantian provenance.

The current study assessed the lateralization of function hypothesis (Rilea, S. L., Roskos-Ewoldsen, B., & Boles, D. (2004). Sex differences in spatial ability: A lateralization of function approach. Brain and Cognition, 56, 332–343) which suggested that it was the interaction of brain organization and the type of spatial task that led to sex differences in spatial ability. A second purpose was to evaluate explanations for their unexpected findings on the mental rotation task. In Experiment 1, participants completed the Water Level, Paper Folding, and mental rotation tasks (using an object-based or self-based perspective), presented bilaterally. Sex differences were only observed on the Water Level Task; a right hemisphere advantage was observed on Water Level and mental rotation tasks. In Experiment 2, a human stick figure or a polygon was mentally rotated. Men outperformed women when rotating polygons, but not when rotating stick figures. Men demonstrated a right hemisphere advantage when rotating polygons; women showed no hemisphere differences for either stimulus. Thus, hemisphere processing, task complexity, and stimulus type may influence performance for men and women across different spatial measures. 相似文献

Hemispatial neglect is a common and disabling consequence of stroke. Previous reports examining the relationship between gender and the incidence of unilateral spatial neglect (USN) have included either a large numbers of patients with few neglect tests or small numbers of patients with multiple tests. To determine if USN was more common and/or severe in men or women, we examined a large group of patients (312 right-handed) within 24 hours of acute right hemisphere ischemic stroke. Multiple spatial neglect tasks were used to increase the sensitivity of neglect detection. No differences based upon gender were observed for the prevalence, severity, or a combined task measure of USN. 相似文献
