Spatial Skills
Spatial visualization ability or visual-spatial ability is the ability to mentally manipulate 2-dimensional and 3-dimensional figures. It is typically measured with simple cognitive tests and is predictive of user performance with some kinds of user interfaces. Measurement The cognitive tests used to measure spatial visualization ability including mental rotation tasks like the Mental Rotations Test or mental cutting tasks like the Mental Cutting Test; and cognitive tests like the VZ-1 (Form Board), VZ-2 (Paper Folding), and VZ-3 (Surface Development) tests from the Kit of Factor-Reference cognitive tests produced by Educational Testing Service. Though the descriptions of spatial visualization and mental rotation sound similar, mental rotation is a particular task that can be accomplished using spatial visualization. The Minnesota Paper Form Board Test involves giving participants a shape and a set of smaller shapes which they are then instructed to determine which combinatio ...

Ability
Abilities are powers an agent has to perform various actions. They include common abilities, like walking, and rare abilities, like performing a double backflip. Abilities are intelligent powers: they are guided by the person's intention and executing them successfully results in an action, which is not true for all types of powers. They are closely related to but not identical with various other concepts, such as disposition, know-how, aptitude, talent, potential, and skill. Theories of ability aim to articulate the nature of abilities. Traditionally, the ''conditional analysis'' has been the most popular approach. According to it, having an ability means one would perform the action in question if one tried to do so. On this view, Michael Phelps has the ability to swim 200 meters in under 2 minutes because he would do so if he tried to. This approach has been criticized in various ways. Some counterexamples involve cases in which the agent is physically able to do something b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Toronto
The University of Toronto (UToronto or U of T) is a public research university in Toronto, Ontario, Canada, located on the grounds that surround Queen's Park. It was founded by royal charter in 1827 as King's College, the first institution of higher learning in Upper Canada. Originally controlled by the Church of England, the university assumed its present name in 1850 upon becoming a secular institution. As a collegiate university, it comprises eleven colleges each with substantial autonomy on financial and institutional affairs and significant differences in character and history. The university maintains three campuses, the oldest of which, St. George, is located in downtown Toronto. The other two satellite campuses are located in Scarborough and Mississauga. The University of Toronto offers over 700 undergraduate and 200 graduate programs. In all major rankings, the university consistently ranks in the top ten public universities in the world and as the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spatial Ability
Spatial ability or visuo-spatial ability is the capacity to understand, reason, and remember the visual and spatial relations among objects or space. Visual-spatial abilities are used for everyday use from navigation, understanding or fixing equipment, understanding or estimating distance and measurement, and performing on a job. Spatial abilities are also important for success in fields such as sports, technical aptitude, mathematics, natural sciences, engineering, economic forecasting, meteorology, chemistry and physics. Not only do spatial abilities involve understanding the outside world, but they also involve processing outside information and reasoning with it through representation in the mind. Definition and types Spatial ability is the capacity to understand, reason and remember the visual and spatial relations among objects or space. There are four common types of spatial abilities which include spatial or visuo-spatial perception, spatial visualization, mental fold ...

Proof Without Words
In mathematics, a proof without words (or visual proof) is an illustration of an identity or mathematical statement which can be demonstrated as self-evident by a diagram without any accompanying explanatory text. Such proofs can be considered more elegant than formal or mathematically rigorous proofs due to their self-evident nature. When the diagram demonstrates a particular case of a general statement, to be a proof, it must be generalisable. A proof without words is not the same as a mathematical proof, because it omits the details of the logical argument it illustrates. However, it can provide valuable intuitions to the viewer that can help them formulate or better understand a true proof. Examples Sum of odd numbers The statement that the sum of all positive odd numbers up to 2''n'' − 1 is a perfect square—more specifically, the perfect square ''n''2—can be demonstrated by a proof without words. In one corner of a grid, a single block repres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonverbal Learning Disorder
Nonverbal learning disability (NVLD) is a neurodevelopmental disorder characterized by core deficits in visual-spatial processing in the presence of intact verbal ability. Additional diagnostic criteria include Average to Superior verbal intelligence and deficits in visuoconstruction abilities, fine-motor coordination, mathematical reasoning, visuospatial memory and social skills. In clinical settings, some diagnoses of attention deficit hyperactivity disorder would be more appropriately classified as NVLD. Signs and symptoms Considered to be neurologically based, nonverbal learning disorder is characterized by: * impairments in visuospatial processing * discrepancy between Average to Superior verbal abilities and impaired nonverbal abilities such as: ** visuoconstruction ** fine motor coordination ** mathematical reasoning ** visuospatial memory ** socioemotional skills People with NVLD may have trouble understanding charts, reading maps, assembling jigsaw puzzles, and usin ...
