Final answer:
Communal rituals involving repetitive actions and/or words are likely to produce a communal ritual ASC, an altered state of consciousness. These rituals induce a trance-like state and create a sense of unity among participants.
Step-by-step explanation:
Rituals involving repetitive actions and/or words are likely to produce an altered state of consciousness (ASC) known as communal ritual ASC. Communal rituals are performed by a group of people with a shared intention, such as religious ceremonies or cultural traditions. These rituals often involve repetitive actions, such as dancing or chanting, and repetitive words, such as incantations or prayers. The repetitive nature of these rituals helps to induce a trance-like state and create a sense of unity and connection among the participants. For example, in the Hup community of the northwest Amazon, incantations are used by elders for protection and healing, and the repetition of the incantations helps to enhance their effectiveness.
