Large-group awareness training (LGAT) refers to activities usually offered by groups linked with the human potential movement which claim to increase self-awareness and bring about desirable transformations in individuals' personal lives. They are noted for being unconventional and often take place over several days.LGAT programs may involve several hundred people at a time.
Though early definitions cited LGATs as featuring unusually long durations, more recent texts describe the trainings as lasting from a few hours to a few days.
Forsyth and Corazzini cite Lieberman (1994) as suggesting "that at least 1.3 million Americans have taken part in LGAT sessions".
