Reported benefits include improved communication, social engagement, attention, motivation, and reduced anxiety for some participants. Proposed mechanisms are multisensory stimulation, nonjudgmental interaction, novelty, and reward. Evidence is limited and mixed; few randomized controlled trials exist, many studies use small samples (often n< 30), lack blinding, and have short follow-up
