AS Level Psychology (9990) Case Studies Practice Exam

The main idea here is that memory strength across items that fall in a mild-to-moderate range produces balanced, non-biased outcomes. When scenes are only moderately distinctive, they aren’t strong enough to guarantee recall for most items, nor weak enough to guarantee forgetting for many. That mid-range cue strength leads to a similar mix of remembered and not-remembered responses across those scenes, so the distribution of memory outcomes ends up being comparable rather than skewed in one direction. If you saw a skew toward remembering, you’d expect most items to be recalled; if toward forgetting, most would be forgotten. The option about being only familiar doesn’t fit because the pattern described is a shared, mid-range distribution, not a restriction to familiarity alone.
