In psychology, parallel processing is the ability of the brain to simultaneously process incoming stimuli of differing quality. [1] Parallel processing is associated with the visual system in that the brain divides what it sees into four components: color , motion , shape , and depth .
Studies of sensory processing in humans and other animals has traditionally been performed one sense at a time, [10] and to the present day, numerous academic societies and journals are largely restricted to considering sensory modalities separately ('Vision Research', 'Hearing Research' etc.). However, there is also a long and parallel history ...
Predictive coding was initially developed as a model of the sensory system, where the brain solves the problem of modelling distal causes of sensory input through a version of Bayesian inference. It assumes that the brain maintains an active internal representations of the distal causes, which enable it to predict the sensory inputs. [ 5 ]
For example, if in a search task the reaction times vary proportionally with the number of elements, then it is evident that this cognitive process of searching involves serial instead of parallel processing. Psychophysical responses. Psychophysical experiments are an old psychological technique, which has been adopted by cognitive psychology.
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
Some later stages of human visual processing can represent object locations relative to each other or to the scene. Regarding representation of relative locations, the relative positions of objects can be represented with an imaginary polygon , with each target a different vertex of that polygon.
[1] [2] [5] An example given of parallel evolution is the independent development of small body sizes in two or more descendent populations in a new, similar environment that diverged from the same ancestral population. [1] Parallel speciation differs from this slightly, as it is a form of parallel evolution, but the traits that are ...
Dual process theory within moral psychology is an influential theory of human moral judgement that posits that human beings possess two distinct cognitive subsystems that compete in moral reasoning processes: one fast, intuitive and emotionally-driven, the other slow, requiring conscious deliberation and a higher cognitive load.
