Afterword: The flexibility and permeability of personal space

Personal space includes interpersonal space and reaching space. Developmental psychology studies these spaces using consensual research paradigms based on clinical observations and experimental research. The size of these spaces varies depending on social context and on intrusion tolerance. They are studied in comparative research, including studies on children or adults with autism. They also vary according to culture, gender, corpulence, and type of attachment. The use of digital techniques and virtual environments opens avenues for applied or basic research on this topic.
