The Studies Of Visual Imageryprocessing System's Training Effect

Visual imagery ability was seen as the core of spatial intelligence,its non-logic and its consciousness characteristics had the important function in creative thinking:the function andproperties of the visual imagery was a large extent to restrict the spatial intelligence of mankind, and it also restricted the development level of intelligence.The cognitiveprocess of visual image was a kind of high classprocesses of spatial cognitive,this kind of high class of cognitionprocess correlated with the specificity of cerebral functions.It was significant to improve the forecasting veracity of the special occupationpersonnel estimate and to raise thepertinency and validity of clinical rehabilitative for various brain function obstacle that clarified theplasticity of visual cognition functionplasticity level from two angles of the behaviorplasticity and the brainplasticity. On the foundation that the Kosslyn high level visualprocessing subsystem theories,the research inquiry into the training effect and brain mechanism of the visual imageryprocessing subsystem with the means of the behavior experiment,SEM and ERPs,and build up the behavior experiment model, SEM and the model of brain waves activation,andprovide the beneficial complement and references for the research that cognitive neural science.According to the theories of Kosslyn high-level visual cognitionprocessing subsystem and theplasticity of human behaviors and the brain mechanism,comprehend and describe the characteristic that various typical missions of spatial cognitiveprocesses.Do the detailed analysis to theplasticity level of visual imageryprocessing subsystems and their combine thatpasses a series of normative cognition experiments,and structure the confirmatory model of visual imagery cognitiveprocessing system that apply the technique of SEM;at one time,in the cognitive nerve science,use the technique of ERPs to discuss the bring mechanism of visual imageryprocess,and from theplasticity and the stability of the brain functionplasticity to discuss the specificity of different visual spatial imagery missions and their intercommunity.This research adopts the imagery rotation,imagery scan,coordinate and category spatial judgment to the cognitive mission that the study the characteristic of the visual imageryprocessing subsystem.At the international research field,these four kinds of imageryprocessing is the core factors that studies the high-level visual spatialprocessing,and it wasproved in frontal studies that the four kinds of imageryprocessing belong to four visual imageryprocessing subsystems.Around the four kinds of visual imageryprocessing subsystem,we strictly control the experiment condition, and record subjects' behavior reaction data and ERPs.This research is constituted by fourparts:(1) The behavior studies of training effect of visual imageryprocessing subsystems;(2) The behavior studies of integration of the visual imageryprocessing subsystems and their training effect;(3) The SEM of visual imageryprocessing system;(4) The ERPs studies of training effect of visual imageryprocessing subsystems.Comprehensive experiment results and relevant discussion,the studies draw some conclusions:1.The four kinds of imageryprocessing mechanism that is image rotation,image scan, category and coordinate relations judgment is not only discriminate each other but also contact mutually.Their differentprove that it involves special subsystemprocessing,but their contact then cause affect each other in many missionprocess.Such result elucidation that the four imageryprocessing has the same foundationprocessing subsystem,and also have its specialprocessing mechanism.There have this kind of trait that when theprocessing resources conflict in combined tasks,the simple task has beenprocessed first.2.There is observably training effect in the four imageryprocessing,those is image rotation,image scan,category and coordinate relation judgment after short date train.Such result seems different to with the result of former research,but our research mainly is aim at the variety characteristics of four kinds of imageryprocessing tasks after the shortperiod training,but foregone studies are the establishment at the suppose of which special community is through long-term system of training,it express the training effect that is the imageryprocessing under the condition of long-term of training.Therefore,it can't say our research results are quite the contrary with former researches simply,it just to announce the imageryprocessing's training effect under two kinds of different conditions.3.The four kinds of imageryprocessing that is image rotation,image scan,category and coordinate spatial relations judgment still express its each special stability characteristics.Our studies although announce the variety characteristics of the four kinds of imageryprocessing's training effects with short date train,to some extent still appeared the stability characteristics that four kinds of imageryprocessing:the two imageryprocessing of image rotation and coordinate spatial relation judgment are subjected to the disciplinal influence more easily,it represents that theperformance of different training levels have remarkable differentia each other;But image scan and category spatial relation judgment is relative stably,it represents that it may need longer time training to causableperformance exaltation.4.The four imagery abilities of image rotation,image scan,category and coordinate spatial relation judgment occupy different weight in whole imagery ability.Image scan the specific weight have biggest,next is image rotation and coordinate spatial relation,the specific weight that category spatial relation have is light most.
