Selective Attention And Central Executive Function Sub-components

From the information science point of view, the central executive function is an initiative of the external information processing, rational allocation of mental resources and to coordinate the control of information management systems. Selective attention itself is the information from the complex who were screened out useful information on mental processes. Note that in fact reflected in the working memory of a number of tasks competing for cognitive resources between the control selection process. Itself and is closely related to executive function. In order to study this relationship between them, from the central executive function of the three classic sub-components to proceed with selective attention to doing research. In this study, college students as subjects, the paper 218 college students were taken to be tested within the design, that all the subjects have done all of the experimental task. Do first selective attention tasks, which leads into the effectiveness of attention task, the target number of new heterosexual and interferences of three levels.In the experiment, the computer automatically presents all data and records, the use of correlation analysis, analysis of variance and regression analysis methods reached the following conclusions:(1) boys and girls as an effective novel target in the cue and invalid cue targets non-novelty interferences under the conditions with the increase in the number gradually increased reaction time. Changes in the number of interferences on the male and female students clues to changes in the number of distractor cues effectively target and non-novel novel clues to the non-valid target to have a more significant interference; instead of an effective novel target cues and clues invalid target does not exist novel interference. Changes in the number of interferences on the arts and science students and effective novel target cues and clues to novel targets of non-void significant interference; while clues to novel and effective targets and novel targets invalid cues no interference. (2) clues in the trail of non-valid under the conditions of novelty as the target number of distractors increases gradually increased reaction time, regardless of whether the effective and leads to changes in the number of distracters, the individual targets of novel processing speed of selective attention not affected, have been maintained at a relatively stable level. However, distractor number of changes on non-novel target was not significant, while novel target of significantly; effectiveness leads to new heterosexual target of processing had no significant effect, while the non-novel target of processing is a significant impact. (3) selective attention and switching functions in addition there is no correlation, and the suppression, there is the refresh functions are more significantly related to, and refresh also a negative correlation, inhibition, and refresh there is a significant negative correlation. Through regression analysis, refresh function can explain 3.1% of selective attention.
