On 19 August 2007, the American Psychology Association (APA) voted to bar participation, to intervene to stop, and to report involvement in a wide variety of interrogation techniques as torture, including "using mock executions, simulated drowning, sexual and religious humiliation, stress positions or sleep deprivation", as well as "the exploitation of prisoners' phobias, the use of mind-altering drugs, hooding, forced nakedness, the use of dogs to frighten detainees, exposing prisoners to extreme heat and cold, physical assault and threatening the use of such techniques against a prisoner or a prisoner's family."
