A Study in Hemispheric Specialization

            
             Hemispheric specialization showed how the two different hemispheres held advantage in conducting various tasks. A divided visual field task tested whether pattern recognition would have an advantage towards a hemisphere. Based on previous research it is hypothesized that the right hemisphere would have an advantage towards tactile pattern recognition. This experiments had eight participants participated in a task that separated images into two different categories. One that had distinct patterns or one that did not. The results showed that the reaction times were unreliable and it was not consistent with the current research. Based on the result of this experiment, there was not an advantage in the hemispheres that distinguished patterns that showed that global processing was not apart of pattern recognition. .
             Introduction.
             What part of the brain does a person use when distinguishing whether if there was a pattern present? Previous psychological experiments have discovered that different side of the hemisphere was better at performing certain type of tasks. Gazzaniga and colleagues (2009) had summarized studies of hemispheric specialization from split patients to regular subjects that have demonstrated hemispheric asymmetry. There were experiments done that showed that language and detail processing had more of an advantage in the right hemisphere while visuospatial and whole processing was in the right hemisphere. Milner and colleague (2001) studied how split-brain patients would memorize distinct patterns after a delay and showed that the right hemisphere was better at performing that task. The recent researches didn't focus on how regular patients responded to pattern recognition and only tested the subjects' ability to memorize patterns and how it was recalled later. This research applied regular college students in a divided visual field task that indicated the right hemisphere would be the part that is responsible for pattern recognition.

... ears, the right ear (LH) is better at processing language-like signals compared to the left (RH). Roger Sperry's study of split-brain patients, whose corpus callosum was severed due to epilepsy, also confirmed hemispherical specialization. In the study, the patients could name and retrieve the object of the word presented to their right visual field (left-hemisphere-LH) but ... stimuli. Sperry's study concluded that the LH is the dominant hemisphere for active language processing (Parker & Riley,2010). Results from brain scans and imaging have also established that there was typically m...

... to be the part of us that controls everything. This surgical procedure called "commissurotomy" was pioneered by Roger Sperry and Ronald Myers in the late nineteen fifties. Initially they began experimenting with cats, and later proceeded to study monkeys. In nineteen sixty-one the first human patient was subject to this new procedure. The surgery worked well as a cure for patients who ... the right hemisphere was distinctly superior in spatial tasks such as arranging blocks and drawing three dimensional pictures. Researchers showed identical images to each hemisphere and had the correspon...
