Effects Of Material Types On Task Transformation In Endogenous Preparation And Exogenous Regulating

Switching process is an important of executive control. the research chosenormal undergraduates as participants and used Arabic numerals and Chinese asexperimental materials. Using Guo Chunyan revised task switching paradigm.Respectively discusses unidimensional betwen different material properties anddouble dimension of the same material for working memory endogenous preparationstage and the effects of exogenous regulating stage.The results suggested:1. The task switch and task repetition are diferent course.2. Under the condition of foreknowledge, switch process contents endogenouspreparation and exogenous adjustment courses, and no-foreknowledge it work onlyby exogenous adjustment.3. The same doubled material properties of task switching no difference betweenthe different material, the influence of the same material doubled attribute of taskswitching and the influence of different materials there are differences between theunidimensional attributes to the influence of task switching.4. Task switching within the same processing mechanism transformation and thetransformation mechanism between different processing mechanism may be different.
