In the past few years, evidence has accumulated which suggests that many well-known spatial distortions might be related to systematic biases in two perceived angular variables - the perceived direction of gaze (e.g. gaze declination from horizontal) and the perceived optical slant of surfaces (Durgin and Li, 2011; Durgin and Li, in press; Durgin, Li and Hajnal, 2010; Li and Durgin, 2009, 2010; Li, Phillips and Durgin, 2011). It has been shown that in the range between 0° and 50°, both the perceived declination of gaze and the perceived optical slant of surfaces are expanded with a linear gain of about 1.5; perceived optical slant also increases as a function of viewing distance. An angular expansion hypothesis has been proposed which assumes that (1) there are perceptual biases in these two angular variables and (2) that the relationships between these and other perceived spatial variables otherwise still adhere to a Euclidean geometry. Specifically, it has been shown that such an angular ...

To reinvestigate how place cells represent the environment, we made recordings as rats ran around inside a gray cylindrical apparatus with two distinct stimuli, a white card and a black card, pasted on the apparatus wall. There were four main findings. (a) In agreement with earlier work (Muller and Kubie 1987; Thompson and Best 1990), firing fields are stable for days when place cells are repeatedly recorded with the two cards in standard positions. (b) Equal rotations of the two cards on the cylinder wall caused firing fields to rotate by the same amount. Firing fields were otherwise unaltered by such rigid rotations. This nearly ideal control of firing fields by specific stimuli is also in agreement with previous work (OKeefe and Conway 1978; Muller and Kubie 1987; Sharp et al. 1990; Gothard et al. 1996; Cressant et al. 1997). (c) The only effect of removing one card and rotating the other was to cause uniform rotations of all firing fields. Thus, removal of one card did not cause firing ...

Verbal representations of space are related to the space they describe by a sign relation comprising three components. The first is the sign vehicle consisting of the sequence of words which describe the spatial environment. The second is the object of reference, the spatial environment as such, and the third is the mental representation of the spatial perception.Within this triad, space is never an unsemiotically given piece of reality. Space is always a semiotic phenomenon insofar as its structure depends on the process of human perception. Even as a referential object, space is not an independently given phenomenon of the "real" world itself but depends on the cognitive capacity and structure of the perceiving mind. ...

SpatiaLite does not implements any kind of spatial index, mainly because SQLite in its own does not supports R-trees, but only B-trees. Please note well that this one may be a severe limitation, if you need to fastly access a very large data set by using some spatial selection criterion; but if yours data sets are not too large [less than 10.000 rows, just to fix an arbitrary limit] lacking of any kind of spatial index may be practically unnoticed ...

Recent research shows that the spatial language parents use when talking to their children predicts their childs spatial language development (Pruden & Levine, in preparation). But parent spatial talk does not fully account for child spatial language. This study investigates whether the gestures parents produce along with spatial language have added value in predicting childrens acquisition of spatial language, over and above spatial language alone.. There are several reasons to expect that this may be the case. First, with respect to language acquisition in general, children are sensitive to the gestures of others in both conversational and pedagogical situations (Goldin-Meadow, 2003). At home, parents gestures predict childrens gestures and, in turn, their vocabulary size (Rowe & Goldin-Meadow, 2009). In instructional situations, children learn more from spoken instruction if it is accompanied by gesture than if it is not (Church, Ayman-Nolley, & Mahootian, 2004; Valenzeno, Alibali, & ...

AU - Macaluso, Emiliano. PY - 2004/12. Y1 - 2004/12. N2 - We studied neural interactions between brain areas involved in exogenous (stimulus-driven) control of visuospatial attention. With event-related functional magnetic resonance imaging (fMRI), we investigated changes of connectivity during shifts of spatial attention from an attended location to a previously unattended target location. Using a 3-T scanner, fMRI data were acquired from three healthy volunteers. According to a central visual cue, participants directed endogenous spatial attention to the left or the right visual hemifield for blocks of 56 s. Peripheral visual targets were presented unpredictably in either the attended hemifield (valid trials, 80%) or in the unattended hemifield (invalid trials, 20%) and participants performed a two-alternative ...
TY - JOUR. T1 - Dynamically detuned oscillations account for the coupled rate and temporal code of place cell firing. AU - Lengyel, Máté. AU - Szatmáry, Zoltán. AU - Érdi, Péter. PY - 2003/9/22. Y1 - 2003/9/22. N2 - Firing of place cells in the exploring rat conveys doubly coded spatial information: both the rate of spikes and their timing relative to the phase of the ongoing field theta oscillation are correlated with the location of the animal. Specifically, the firing rate of a place cell waxes and wanes, while the timing of spikes precesses monotonically as the animal traverses the portion of the environment preferred by the cell. We propose a mechanism for the generation of this firing pattern that can be applied for place cells in all three hippocampal subfields and that encodes spatial information in the output of the cell without relying on topographical connections or topographical input. A single pyramidal cell was modeled so that the cell received rhythmic inhibition in phase ...
Imagine struggling to see, listen, or make movements in half of your environment. This is typical for individuals who suffer from unilateral spatial neglect, a common post-stroke deficit of attention to objects or events on the side opposite of the brain injury. The condition has a major impact on the everyday lives of stroke survivors and has shown to be a strong predictor of disability.
ndividuals with Williams syndrome typically show relatively poor visuospatial abilities in comparison to stronger verbal skills. However, individuals level of performance is not consistent across all visuospatial tasks. The studies assessing visuospatial functioning in Williams syndrome are critically reviewed, to provide a clear pattern of the relative difficulty of these tasks. This prompts a possible explanation of the variability in performance seen, which focuses on the processing demands of some of these tasks. Individuals with Williams syndrome show an atypical processing style on tests of construction, which does not affect tests of perception.. ...
Functional MRI was used to examine cerebral activations in 12 subjects while they performed a spatial attention task. This study applied more stringent behavioural and cognitive controls than previously used for similar experiments: (i) subjects were included only if they showed evidence of attentional shifts while performing the task in the magnet; (ii) the experimental task and baseline condition were designed to eliminate the contributions of motor output, visual fixation, inhibition of eye movements, working memory and the conditional (no-go) component of responding. Activations were seen in all three hypothesized cortical epicentres forming a network for spatial attention: the lateral premotor cortex (frontal eye fields), the posterior parietal cortex and the cingulate cortex. Subcortical activations were seen in the basal ganglia and the thalamus. Although the task required attention to be equally shifted to the left and to the right, eight of 10 subjects showed a greater area of activation in the

Here, a novel approach to motion metrology is discussed. A structured light pattern specifically coded for digital signal processing is positioned onto a fiduciary of the patient. As the patient undergoes spatial transformations in 6 DoF (degrees of freedom), a high-resolution CCD camera captures successive images for analysis on a computing platform. A high-speed image processing algorithm is used to calculate spatial transformations in a time frame commensurate with patient movements (10- 100 ms) and with a precision of at least ...

The middle panels (labeled B) show the mean firing rate response to each of the composite forms tested (5 × 16 array) at the most responsive spatial location. The adjacent panels to the right show the Z scores of the responses after subtracting the mean spatial response (see Experimental Procedures and Figure S1A, available online, for details of assessing significance). Example neuron I is preferentially tuned Selleckchem MEK inhibitor to straight shapes, neuron II to medium-curvature shapes, and neuron III to high-curvature/C shapes. Neuron IV had a significant spatial response. but no significant shape selectivity. The distribution of spatial and shape selective tuning is shown in Figure 1B. Across the population, 80 of 93 neurons showed significant shape selectivity while a smaller subset (n = 13, labeled in blue) had spatial tuning without significant shape tuning. We did not analyze this subset further. Furthermore, among neurons with significant shape selectivity, those preferring either ...
Neurophysiological research has led to detailed mechanistic theories about how spatial locations and headings are represented in the brain and used in memory and navigation. INTRODUCTION 0369.001 The term`spatial cognition covers processes controlling behaviour that must be directed at particular locations, or responses that depend on the location or spatial arrangement of stimuli. There are many circumstances in which such processes are required for adaptive behaviour, and they are exhibited in creatures as diverse as bees, birds, rats and primates. At the most basic level, an organism must be able to flee from a dangerous location to a safer place. It may also need to return to a location where food is abundant or has been stored; to act upon a stimulus at one location, while temporarily ignoring other stimuli; or to navigate from one place to another by an efficient route, avoiding obstacles. All of these behaviours seem to demand some sort of spatial representation; a neural code that distinguishes
We develop a two-stage spatial point process model that introduces new characterizations of activation patterns in multisubject functional Magnetic Resonance Imaging (fMRI) studies. Conventionally multisubject fMRI methods rely on combining information across subjects one voxel at a time in order to identify locations of peak activation in the brain. The two-stage model that we develop here addresses shortcomings of standard methods by explicitly modeling the spatial structure of functional signals and recognizing that corresponding cross-subject functional signals can be spatially misaligned. In our first stage analysis, we introduce a marked spatial point process model that captures the spatial features of the functional response and identifies a configuration of activation units for each subject. The locations of these activation units are used as input for the second stage model. The point process model of the second stage analysis is developed to characterize multisubject activation patterns by
This study investigated whether eye proprioception contributes to visual localization. We tested whether a patient with a presumed deficit in eye proprioception after a focal lesion in the left postcentral gyrus made more errors in locating a visual target relative to the head midline compared with an aged-matched control group. Although the patient was as accurate and precise as the control group under the normal, baseline condition, she exhibited a significant error when the position of one eye was perturbed peripherally. In this condition, we found a shift to the left in perceived straight ahead when the task was executed with the left, contralesional eye. This corresponds to a shift toward the nose in perceived eye position, in the direction of the applied force. The direction of this shift is identical with that produced by a push after 1 Hz rTMS in healthy subjects, a procedure that decreased the excitability of the eye proprioceptive area (Balslev and Miall, 2008). The illusory eye ...

Abstract. Spatial cognition has been well examined using various psychological perspectives. Here we suggest that this previous research can be utilized to provide insight into source-code navigation and program comprehension. In our model, code represents an abstract space that must be navigated using the same cognitive strategies as for natural environments. Thus, when navigating codespace computer programmers face many of the same challenges as people navigating within the real world, and consequently, will likely rely on similar skills and strategies. In support of this observation, we explore from a theoretical perspective the use of spatial cognition during program comprehension. Examination reveals that research in spatial cognition provides, albeit currently unproven, explanations for programmer behaviours during program comprehension activities. To validate our model, we suggest a preliminary experiment to explore the existence of codespace.. ...
The remainder of the week was filled with keynote addresses, invited talks - one of which was presented by SILCs Nora Newcombe - student poster sessions, and student paper presentations. Corinne Holmes, a SILC graduate student at Temple University, found the student paper presentations to be especially helpful. She stated, "As a current project of mine enters the final stages, Im in the process of developing a series of follow-up studies, one of which was going to examine the effect of physical rotation and perspective taking on spatial memory for imagined inter-object locations. Adamantini Hatzipanayioti presented a paper on just that, ultimately saving me from conducting a study that has already been done. This example embodies why Spatial Cognition is such a valuable resource for both upcoming and established researchers - it makes currently unpublished research public within the spatial cognition community." Another SILC graduate student from Temple University, Steven Weisberg, found the ...
