Summary
The spatial-size association of response codes (SSARC) effect shows size influences spatial responses, but not vice-versa. This suggests size-to-space associations are asymmetrical, impacting cognitive theories.
Area of Science:
- Cognitive Psychology
- Human-Computer Interaction
- Neuroscience
Background:
- The spatial-size association of response codes (SSARC) effect links stimulus size to spatial responses.
- Theoretical accounts differ on the symmetry of size-space associations.
Purpose of the Study:
- To investigate the reciprocity of SSARC effects.
- To determine if spatial location can influence size judgments as strongly as size influences spatial responses.
Main Methods:
- Compared compatibility effects in size-location and location-size verbal choice-response tasks.
- Participants responded verbally to stimuli in compatible and incompatible mappings.
Main Results:
- A regular SSARC effect was observed in the size-location task.
- No reciprocal SSARC effect was found in the location-size task when outliers were excluded.
- Small reciprocal effects appeared when outliers were included.
Conclusions:
- Associations between physical size and spatial responses are strongly asymmetrical.
- Physical size primes spatial responses more than spatial position primes size responses.
- Findings challenge some, but support other, theoretical accounts of SSARC effects.

A space truss is a three-dimensional counterpart of a planar truss. These structures consist of members connected at their ends, often utilizing ball-and-socket joints to create a stable and versatile framework. The space truss is widely used in various construction projects due to its adaptability and capacity to withstand complex loads.
At the core of a space truss lies the fundamental unit known as the tetrahedron. This structure is composed of six members that form a three-dimensional shape...

01:26Gauss's Law: Spherical Symmetry
7.6K
A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if the system is rotated, it doesn't look different. For instance, if a sphere of radius R is uniformly charged with charge density ρ0, then the distribution has spherical symmetry. On the other hand, if a sphere of radius R is charged so that the top half of the sphere has a uniform charge density ρ1 and the bottom half...

By definition, a spherically symmetric body has the same moment of inertia about any axis passing through its center of mass. This situation changes if there is no spherical symmetry. Since most rigid bodies are not spherically symmetric, these require special treatment.
The relationship between the angular momentum of any rigid body and its angular velocity, both of which are vectors, involves the moment of inertia. The moment of inertia is a scalar quantity only for spherically symmetric...

01:27Gauss's Law: Planar Symmetry

A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...

01:20Gauss's Law: Cylindrical Symmetry

A charge distribution has cylindrical symmetry if the charge density depends only upon the distance from the axis of the cylinder and does not vary along the axis or with the direction about the axis. In other words, if a system varies if it is rotated around the axis or shifted along the axis, it does not have cylindrical symmetry. In real systems, we do not have infinite cylinders; however, if the cylindrical object is considerably longer than the radius from it that we are interested in,...
