Paranormal researchers James Houran, Timothy Harte, Michael Hollinshead and Ursula Bielski conducted a series of experiments at Bachelors Grove Cemetery in the 1980s and 1990s. One of these, a photography experiment, was published in the "Journal of Perceptual and Motor Skills" (1997) and found that, while no anomalous images were obtained from Bachelors Grove Cemetery, approximately half of the frames on both infrared and black and white films were unexposed. The results are discussed in terms of ambiguous events being interpreted as meaningful due to paranormal contexts.
