> Models maintain memory of opponent behaviour across turns, but with realistic decay: recent actions are weighted heavily while distant history fades. One exception preserves psychological realism: instances where opponents dramatically exceeded their stated intentions—major betrayals—remain salient regardless of recency, reflecting Kahneman’s peak-intensity effect in human memory formation Kahneman [2011].

If your goal is to measure intrinsic properties of LLMs, don’t smuggle in human psychology. I suspect they needed to do this to make the models more paranoid and distrustful.
