The Influence Of Different Difference Structures On The Detection Of Changes Under The Gaze-cueing Effect Of Endogenous /Exogenous Attention

Blindness is a visual phenomenon in which people cannot capture the occurrence of changes in the visual range.At present,attentional theory,feature integration theory,memory representation theory and more can be used to explain the causes of change blindness.The attention caused by clues can better detect changes and reduce the occurrence of change blindness.Endogenous attention and exogenous attention can be divided according to different sources of clues.Endogenous attention is the top-down conscious attention,and exogenous attention is the bottom-up automatic attention.They have many differences in visual processing.The direct spacing of stimuli and clues has different effects on endogenous attention and exogenous attention.The change blindness is actually the judgment of the similarity and difference of paired stimuli.Differences can be divided into alignable differences and nonalignable differences depending on the structure.Alignable differences refer to the values of different features in the same dimension.Nonalignable differences are different feature values for different dimensions.Another nonalignable differences is that in a pair of contrast stimuli,one stimulus has a feature that another stimulus does not have.Previous studies only examined the role of clues in detecting changes,and did not further classify clues based on actual conditions.In addition,studies have explored the blindness of different degrees of stimulating properties such as color,structure,and position,but did not subdivide the front and back changes according to the difference structure.This study starts from comparing the endogenous attention and exogenous attention to the different detection effects of change detection,and explores the influence of different attention clues and different difference structure types on the change detection under different interval positions.The first experiment is to add the interval blank screen before the change and the clue itself,using 4(attention category: no attention,endogenous attention,exogenous attention,double clue)*3(differential structure: alignable differences,nonalignable differences 1,nonalignable differences 2).The experimental design of is performed by the subject to judge whether there is a change,and the degree of confidence of the subject for the judgment of the subject is counted,and the dependent variable is the reaction time of the button,the correct rate,and the signal detection theory.In the second experiment,the interval blank screen is placed between the clue and the changed scene,and the rest is no different from the experiment one.The data results show that:(1)In the process of change detection,the clue can promote the detection of change and prevent the change blindness change.(2)Exogenous attention clues are better at prompting change detection than endogenous attention clues.(3)When two clues appear at the same time,that is,under the condition of double clues,the prompt effect is not as good as the clue alone.(4)In the alignable differences,nonalignable differences 1,and t nonalignable differences 2,it is easier to detect the change of the alignable differences.(5)The blank spacing has a greater impact on endogenous attention.
