It can be derived directly through observing the visual event-related potentials (ERP) data that the main function of spatial attention is the modulation of visual signal processing when the mechanism of visual spatial attention is investigated with ERP. The visual ERPs consisted of several characteristic voltage deflections emerging about 80 ms after the stimulus onset that include the P1 (80~130 ms), N1 (140~200 ms) and P2 (200~250 ms) components.
The total cognitive function,memory,attention,language,visual spatial ability,executive function and clinical features were assessed by MMSE,Recall of Auditory Verbal Learning Test,Stroop Color Words Test,Rey-Osterrich Complex Figure Test,Trail Making Test,Test of Fluency in Language and clinical dementia rating respectively.
Among patients with deficiency of cognitive function,the ability of memory ,intention of general knowledge,numeral reasoning,vision space,harmony vision movement,abstract shaping and project judgement might be damaged evidently.
On the basis of these research, we analyze the computation model of synthesizing vision space, in order to complete video image synthesis, we study the theory of IBR and binocular stereo vision, and implement the algorithm of PDE based dense disparity map estimation.
Conclusions: ERP elicited by visual-spatial attention can detect the existence of ADHD children's attention deficit and it's degree,and provide objective evidence for clinical diagnosis and evaluation methylphenidate treatment effect.
Disturbances of the regular structure of the visual space was done using computer modeling of the Hering visual illusion.
The authors compared the values of postural responses under various conditions of visual control, namely, with normal vision, eyes closed, right-left inversion of the visual space by prismatic spectacles, central vision, and diffuse light.
Linear and nonlinear models of the visual space arising in human consciousness upon visual perception of the surrounding world are proposed.
The association of neglect with injury to this area suggests it may play an important role in directing attention in visual space.
Visual space and the practice of viewing: The dance of death at Meslay-Le-Grenet
The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability.
Measures of memory, executive function, visual spatial skills, and verbal fluency discriminated best, and discriminability was at least comparable to that of traditional neuropsychological tests in these domains.
We assessed memory, attention, visual spatial skills, and executive function in Vietnam combat veterans with (n = 19) and without (n = 13) PTSD.
The paper addresses problems of the development of visual spatial functions of the right hemisphere of the human brain in ontogeny and phylogeny.
The distribution of latencies to chiasm stimulation and the average visual spatial resolution were within the normal range in both A and A1 layers.
A 61 year-old right handed man, who suffered from right cerebral infarction with evidences of visual-spatial neglect and constructive disorder, was reported.
In order to investigate the contribution of different components of working memory to outlining, secondary tasks designed to load on the central executive and visual-spatial sketchpad components of working memory were imposed during outlining.
The problem is reviewed of sex differences and the brain organization of the visual-spatial and verbal-cognitive functions both in adults and in the 5-15-year old children.
Characteristic of men are the integral strategy of the face image recognition, specialization of the right hemisphere for visual-spatial functions, and the tonic inhibitory effect of the right hemisphere on the left one.
Differential effects of visual-spatial attention on response latency and temporal-order judgment
