People tend to remember two moments of an event/sequence of time more than others: the most intense point, and the end. This is the Peak–end rule (pleasingly and correctly with an en dash rather than a hyphen).
I stumbled across this recently in: The way we view free time is making us less happy. The advice there is to 'hack' this rule by, when you're on holiday, for instance, scheduling something intense in the middle and nice at the end, with the intent of enhancing your memory of the event (not to remember it more vividly, per se, but to remember more of it (by stacking time between peak and end) and trying to couch those things positively).
I've no idea if this actually works, but I intend to try it -- and the structure of the rule itself fits with my memory of various past events (though, actually, not necessarily with a singular peak event if there are several that operated slightly differently but were still notably 'peaks').
The 'end' part of this rule put me in mind of recency bias, and a quick survey of the relevant Wikipedia pages tipped me onto: the recency effect/serial-position effect, the Von Restorff effect and leveling and sharpening, which all seem fairly congruent with the peak–end rule.
