Research in event cognition has focused on how people perceive
and remember events under experimental conditions. This
research study aims to explore the temporal duration of
self-reported events from daily life (Sreekumar, et al., 2018;
Zhuang, et al., 2012). The small amount of prior work that
exists suggests that daily event durations have a Gaussian
distribution and that people have prior beliefs that reflect this
reality (Griffiths & Tenenbaum, 2006). Forty-eight participants
provided activity duration data as they went about their
everyday lives for 14 days. Descriptive analyses and activity
duration modeling (mixture models of gaussian, gamma, normal
and exponential distributions) were used to characterize event
durations within activity types. Results show that most of the
events present an exponential pattern of durations, while others
show a bimodal pattern. Although some preplanned events have
a characteristic time, many daily events have a substantial
exponential component.
