SPSS Statistics

Hello, I tried to compare my data to see the mean difference. As shown in the table, the mean differences are the same (1.113) for both comparisons, but another table does not show significant difference. Can you explain to me why this happened? or is there any criteria for this? thank you.

Hello. First of all, thank you for the answers.

Secondly, I am sorry, I happened to send the wrong table. Here I put the complete tabulated result. 

*. The mean difference is significant at the 0.05 level.

Previously, I analyzed these variables by using Repeated Measures ANOVA in SPSS to see the mean differences. As shown in the table, there are the same result numbers of mean difference (1.133) for different comparisons (task 1 vs 2) and (task 1 vs 3). Although they showed the same mean difference, only one shows significance. Also, 2.667 is higher than 1.533 etc. but why does it not show a significant difference? Are there any criteria for this? Or maybe it's because I didn't analyze it correctly.
I am looking forward to receiving your explanation. Thank you.

I read somewhere on the internet which stated that if the value of standard error is lower than the mean difference, it would show a significant difference, and vice versa. Is it correct?
However, some of my data does not show as stated above (you can see my attached file)
