Aliasing in spatially sampled signals (e.g., moiré patterns in digital images) is referred to as spatial aliasing. Aliasing is generally avoided by applying low-pass filters or anti-aliasing filters (AAF) to the input signal before sampling and when converting a signal from a higher to a lower sampling rate.
Naomi Weisstein (January 1, 1939 – March 26, 2015) was an American cognitive psychologist, neuroscientist, author and professor of psychology. Weisstein's main area of work was based in social psychology and cognitive neuroscience.
In cognitive psychology, visuospatial function refers to cognitive processes necessary to "identify, integrate, and analyze space and visual form, details, structure and spatial relations" in more than one dimension. [1] Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1]
This image was scaled up using nearest-neighbor interpolation.Thus, the "jaggies" on the edges of the symbols became more prominent. Jaggies are artifacts in raster images, most frequently from aliasing, [1] which in turn is often caused by non-linear mixing effects producing high-frequency components, or missing or poor anti-aliasing filtering prior to sampling.
Experientially basic and primarily spatial image schemas such as the Containment schema and its derivatives the Out schemas lend their logic to non-spatial situations. For example, one may metaphorically use the term out to describe non-spatial experiences: (4) Leave out that big log when you stack the firewood.
Current literature suggests women have higher level of social cognition. A 2012 review published in the journal Neuropsychologia found that women are better at recognizing facial effects, expression processing and emotions in general. [68] Men were only better at recognizing specific behaviour which includes anger, aggression and threatening ...
Women may not always get the historical credit their male counterparts do, but as these women show, they were always there doing the work. With their fierce determination and refusal to back down, all of these 12 women were not just ahead of their own times, but responsible for shaping ours.
Ambiguous images are important to the field of psychology because they are often research tools used in experiments. [3] There is varying evidence on whether ambiguous images can be represented mentally, [ 4 ] but a majority of research has theorized that mental images cannot be ambiguous.
