In both the physical and academic domains interest has recently grown regarding developmental change in children's perceptions of competence. Recent advances in statistical methodology, such as latent growth modeling, enable the researcher to analyze developmental trends from both an inter- and intraindividual perspective, thus serving to increase our understanding of correlates of change in perceived competence. Using latent growth modeling, the purpose of the present study was to investigate developmental change in children's perceived competence at physical skills, examining maturational factors and chronological age as possible correlates of change. Subjects were male adolescents (N = 94). Data were collected during the child's sixth, eighth, and ninth grade school years. Results revealed a good fit for the hypothesized model, which specified mean level changes in the variables over time and an interrelationship among the latent chronometric common factors. Although a significant relationship existed between maturation and perceived competence, no significant relationship was evident between chronological age and perceived competence. Findings are discussed with particular reference to the utility of latent growth curve models for assessing developmental processes at both the inter- and intraindividual level.
最近，在身体和学术领域，人们对儿童能力认知的发展变化越来越感兴趣。统计方法的最新进展，如潜在增长模型，使研究人员能够从个体间和个体内的角度分析发展趋势，从而有助于增进我们对感知能力变化相关因素的理解。本研究旨在运用潜在增长模型，调查儿童在体育技能方面感知能力的发展变化，考察成熟因素和实足年龄作为变化的可能相关因素。研究对象为男性青少年（N = 94）。数据在儿童六年级、八年级和九年级时收集。结果显示，假设模型拟合良好，该模型规定了变量随时间的平均水平变化以及潜在计时共同因素之间的相互关系。虽然成熟度与感知能力之间存在显著关系，但实足年龄与感知能力之间没有明显的显著关系。我们将结合潜在增长曲线模型在个体间和个体内水平评估发展过程的效用，对研究结果进行讨论。
