For example, raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline. Meanwhile, short-term memory continues to improve until around age 25, when it levels off and then begins to drop around age 35. For the ability to evaluate other people’s emotional states, the peak occurred much later, in the 40s or 50s.
