Yes! Large anions are highly polarizable because they have many electrons far from the nucleus that are easily distorted. On the other hand, small cations have a high polarizing power because they cause large distortions.
In smaller cations, the positively charged nucleus is closer to the outer shell. Therefore it has more power (polarizing power) to draw in an anion and distort it. In large anions, the positively charged nucleus is farther from the outer shell. There for it has less power (easily polarizable) to keep to keep the electrons close which allow the anion to become distorted.
