Developmental sequences for catching a small ball: a prelongitudinal screening.
Developmental sequences are identified for many skills (e.g., hopping and throwing). Sequences are hypothesized but not validated for catching. Two purposes of this investigation were to validate hypothesized catching sequences and examine the importance of task constraints on catching performance. Seventy-two subjects (5-12 years of age) were videotaped as they attempted to catch a small (10-cm) ball, tossed to three locations: (a) directly to the body, (b) at the forehead, and (c) to various other locations. Trials were categorized using developmental sequences including four components: arm preparation, arm reception, hands, and body. The data were analyzed by catching condition using the prelongitudinal screening procedure described by Roberton, Williams, and Langendorfer (1980). Preliminary screening resulted in clarification of descriptions for several developmental levels. Movement sequences for hand and body components were comprehensive and age-related for the groups studied. Task conditions differently constrained children of different ages. Arm components did not meet the Roberton et al. criteria. Combining them may be warranted. Varying ball size or type is needed to test the comprehensiveness of the proposed sequences for other catching skills.
