Based on a 95% significant level it is only all the independent variables , that is no change, addition and Substraction and other indicated that those levels are insignificant since they are greater than 0.05. Based on this no had hoc analysis are advanced. The final column gives the significance of the F ratio.In this case the p value for all the categories is is greater than the α level (0.05), so we fail to reject H0. That is, there is insufficient evidence to claim that some of the means may be different from each other.

Based on this paired sample test the two pairs , there is a statistically significant differences between the two conditions in each pair since the two tailed significant value is less than 0.05,Therefor the differences between the conditions are not due changes but probably due to Change in Naturalistic Scene.
