Abstract This study investigated the reliability with which observers detected movement boundaries from films of human behavior. Five experienced observers microanalyzed 50-frame segments of film for each of 15 designated body parts, attempting to identify the frame on which a movement was initiated, terminated, or where it changed direction. Generally, inter- and intraobserver reliabilities were found to be low at the single-frame level of agreement; only 36% and 40%, respectively, of these observed values were significantly different from chance (p<.05) as determined using the binomial test. However, when the unit of agreement was extended beyond one frame, there was a trend for reliability to increase. From the evidence available, it is suggested that a three-frame unit of agreement might be the optimal balance between reliability magnitude and significance.
