One major advantage of Web-based research lies in its ability to reach and study people who have rare condi-
tions of interest. Another advantage is that, due to the anonymity of the survey situation, the Internet is particu-
larly suited for surveys on sensitive topics. Sexsomnia is a newly identified medical condition whose sufferers
engage in sexual behavior during their sleep. Problematic cases are highly distressing and have forensic impli-
cations. The consensus among opinion leaders in sleep medicine is that sexsomnia may be quite common but
that it often goes unreported because of shame and embarrassment. Thus, little is known about this condition's
demographics and clinical features. This article reports findings from a sample analysis of 20 years of research
on sexsomnia and discusses the results, strengths, and weaknesses of a recent Web-based survey conducted on
the difficult-to-reach clinical population that suffers from sexsomnia.

The Stochastic Activity Network Laboratory for Cognitive Modeling (SANLab-CM) is a new tool that incorporates stochastic operations into activity network modeling (Schweickert, Fisher,&Proctor, 2003). In this article, we discuss the core functionality of SANLab-CM and walk through a case study that expands a previously published single, static path model of telephone operators interacting with customers via a workstation (from Gray, John,&Atwood, 1993) into a stochastic model that generates 55 unique paths with different frequencies and a variety of qualitative properties. Without SANLab-CM, it would have been easy to mistake some of the more frequent critical paths as evidence for alternative strategies for task completion. With SANLab-CM, these critical paths can be shown to be simple emergent properties of variability in elementary cognitive, perceptual, and motor processes.
