This body image study tests the viability of transferring a complex psychophysical paradigm
from a controlled in-person laboratory task to an online environment. 172 female participants made online judgements about their own body size when viewing images of computer-generated female bodies presented in either in front-view or at 45-degrees in a
method of adjustment (MOA) paradigm. The results of these judgements were then compared to the results of two laboratory-based studies (with 96 and 40 female participants
respectively) to establish three key findings. Firstly, the results show that the accuracy of
online and in-lab estimates of body size are comparable, secondly that the same patterns of
visual biases in judgements are shown both in-lab and online, and thirdly online data shows
the same view-orientation advantage in accuracy in body size judgements as the laboratory
studies. Thus, this study suggests that that online sampling potentially represents a rapid
and accurate way of collecting reliable complex behavioural and perceptual data from a
more diverse range of participants than is normally sampled in laboratory-based studies. It
also offers the potential for designing stratified sampling strategies to construct a truly representative sample of a target population.
