Wikipedia on time perception
The Wikipedia article on "time perception". In particular, the section on long-term time perception cites a couple of articles.
* The articles makes the common point that a unit of time as a proportion of one's life decreases with age. A few empirical studies are also cited.
Ukraintseva (2001) wrote an article devoted to the topic and makes several interesting points about time perception over aging. E.g.,
- Ukraintseva argues the rate of aging decreases with age and that this may have relevance to experience of time.
- Ukraintseva also suggests that living may be slower in some sense with age citing examples of slower "metabolic rate, rate of cell proliferation, physical, mental alertness, and the rate of living in general".
Graf and Grondin
Graf and Grondin have an article that reviews the literature on the psychology of time perception and discusses age related differences. However, the article seems to focus more on aspects of performance rather than the subjective experience of time slowing.
- They cite a few studies that suggest that in relation to judging time intervals, older adults may be less accurate.
My own random musings (treat them as you wish) suggest that topics such as flow, goals, rhythm of life, and boredom might also be relevant.
- A feature of being immersed in a state of flow is a sense of time distortion.
- As we get older, perhaps we start to set more long term goals, and this might shape the experience of time and change.
- Increased levels of routinisation and automaticity might also decrease awareness of time passing.
- Perhaps knowing how to avoid boredom would be relevant to time passing.

The above are just a few quick points (it's not my area):
