Rates are defined as the number of occurrences per second. Percents are the percentage of the session during which the specified behaviour was occurring.

^aPercent Successful is defined as the percentage of responses that were coded as successful.

RSB, repetitive and stereotypic behaviour; *p < 0.05; **p < 0.01; see text for more precise tail probabilities.
