Structured time and subjective acceleration of time.
The present paper gives some evidence that differences in subjective time acceleration with aging are correlated with differences in the extent to which time is structured for the individual, as opposed to free time. Lemlich's 1975 hypothesis relating this speeding up of time to the subjective duration of the time interval was only partially supported by the evidence. Subjective change perceptions of happiness were not correlated significantly with this phenomenon of time perception.
