Mother–child communication about location: Giving and following directions for finding hidden objects

Jodie M. Plumert, Kathryn A. Haggerty, Andrew Mickunas, Lauren Herzog, Courtney Shadrick
2012 Developmental Psychology  
The discussion focuses on the roles of spatial proximity and reference frames in mother-child spatial communication.  ...  Older children were more successful in following directions than were younger children, and children were more likely to search successfully in response to a person than to a landmark frame of reference  ...  A related explanation is that person frames of reference have a special status for young children.  ...

On the Arbitrary Choice Regarding Which Inertial Reference Frame Is "Stationary" and Which Is "Moving" in the Special Theory of Relativity

Here and Now: Mapping Space and Time in a Four-Part Frame of Reference Typology

Eve Danziger
2013 Proceedings of the annual meeting of the Berkeley Linguistics Society  
I will apply the distinctions of a four-part spatial frame of reference typology (Danziger 2010) to the language of temporal sequence, arguing that the two intersecting conceptual dichotomies which make  ...  I'll conclude that in the relational analogy between space and other domains, space itself does not emerge as primary or basic relative to the others.  ...  Primary relations of identity among several key frame-of-reference components in Direct frame usage are thus progressively exploded to yield first Allocentric and then, optionally, Extrinsic frames.  ...

Reference Frames for Spatial Inference in Text Understanding [chapter]

Berry Claus, Klaus Eyferth, Carsten Gips, Robin Hörnig, Ute Schmid, Sylvia Wiebrock, Fritz Wysotzki
1998 Lecture Notes in Computer Science  
That is, inferences of spatial relations not given explicitly in a text depend on the frame of reference which is presumed by the human or computer system.  ...  Within our approach a spatial relation between two objects is represented by constraining the position of one of the objects with respect to the reference frame of the other one.  ...  the reference frame and further arguments in favor of an allocentric reference frame.  ...

Where is the donut? Factors influencing spatial reference frame use

HollyA. Taylor, DavidN. Rapp
2004 Cognitive Processing  
First, since objectfacing direction has implications for the cognitive strategies used to determine spatial relations, we assessed how object facing interacted with reference frame use.  ...  From the features of the scene (object-facing direction, located object position) emerged two interactions of interest.  ...  We would also like to thank Laura Carlson and Phil Holcomb for helpful discussions on portions of the data.  ...

Astronomical aberration in the theory of ether and the theory of relativity. A new original interpretation [article]

Daniele Sasso
2009 arXiv   pre-print
A new interpretation of astronomical aberration is given in this paper and it is based on the new theory of reference frames.  ...  The new interpretation confirms the result of classical physics based on the concept of ether and does not confirm the result of Special Relativity based on the constancy of the speed of light.  ...  The TR metodology is based on the Principle of Reference that for the analysis of any physical event sets out the existence of a preferred reference frame and observer.  ...

Representing orientation: A coordinate-system hypothesis and evidence from developmental deficits

Michael McCloskey, Jussi Valtonen, Janet Cohen Sherman
2006 Cognitive Neuropsychology  
We conclude by discussing several issues concerning the interpretation of our results, the COR hypothesis, and the use of developmental deficits as a basis for inferences about normal cognition.  ...  We propose a coordinate-system hypothesis of orientation representation (COR) and show that the hypothesis provides an explicit basis for interpreting orientation errors.  ...  s performance can be interpreted in terms of impairment in representing tilt magnitude and tilt direction when relating object-centred and external reference frames.  ...

Updating of visual orientation in a gravity-based reference frame

Nynke Niehof, Julian J. Tramper, Christian F. Doeller, W. Pieter Medendorp
2017 Journal of Vision  
# The brain can use multiple reference frames to code line orientation, including head-, object-, and gravitycentered references.  ...  In some subjects, a smaller part of the updating error was also related to the change of visual frame orientation.  ...  They showed that the direction errors of the saccade were closely related to the amount of subjective distortion of gravity direction at both the initial and final tilt angle, rather than to the amount  ...

Erik W. Grafarend, Ivan I. Müller, Haim B. Papo, Burkhard Richter
1979 Symposium - International astronomical union  
Modern high accuracy measurements of the non-rigid Earth are to be referred to four-dimensional, i.e., time and space-dependent reference frames.  ...  In the first part problems related to reference directions are investigated, while the second part deals with positions, i.e., with reference origins.  ...  The ultimate goal of this study is the establishment of a reference frame, moving with the Earth in some average sense, in which the geo metric and dynamic behavior of the Earth can be monitored, and whose  ...

2014 Lecture Notes in Geoinformation and Cartography  
This paper introduces and formalizes a frame of reference for projective relations in 3D space that can be used to model human visual perception.  ...  Yet, we can retain ternary relations by anchoring our frame to an ubiquitous reference element: a general sense of vertical direction that, on Earth, can be the expression of gravity force or, in other  ...  A FRAME OF REFERENCE FOR PROJECTIVE RELATIONS IN 3D SPACE In this section we present a frame of reference generating from two reference solids (B and C) and a direction vector (d) that allows for partitioning  ...

In the present study, when muscle torque directions were described in a body-fixed frame of reference, these directions were related almost exclusively to shoulder elevation and/or azimuth; in most cases  ...  However, despite the utility of the concept, few direct attempts have been made to deter- mine the frame of reference for reach-related activity (Georgopou- los, 1995).  ...
