The independent-measures t statistic measures the difference between sample means, and increasing this difference will result in a larger t statistic value and a smaller p-value. This means that it is more likely to reject the null hypothesis, and the effect size (such as Cohen's d) will also increase as the difference between sample means becomes larger.
