Rorschach test
Moses' key experiment was conducted under the auspices of the University of California Institute of Child Welfare. He analysed the personality of an adolescent boy whom he had never met, from a phonograph record of the boy's voice, without face-to-face contact. The boy had previously received an assessment by a psychiatrist that included a Rorschach test. Based on what Moses perceived in the patterns of rhythm, pitch, timbre and prosody of the boy's recorded voice, Moses gave an analysis of the personality of the boy which was found to agree on many points with the Rorschach test findings and the psychiatrist's own report.
