本研究考察了成人判断儿童负担能力时，任务、模型和观察者的某些特征对估计误差的影响。118名成年人被分成4个身高组，在模特在场和不在场的情况下，估计了3名女孩(3.55岁、4.74岁和7.06岁)的身高和垂直伸展能力。计算了恒定误差(CE)(估计-实际值)、绝对百分比误差(APE)(垂直条1-估计/实际值垂直条x 100)和误差倾向(低估、正确判断或高估)。在APE上验证了模型和条件效应。年轻模型的APE大于其他模型(p
This study investigated the influence of some characteristics of the task, the model, and the observer, in the estimation errors of adults while judging children's affordances. One hundred and eighteen adults, divided in 4 height groups, estimated height and vertical reaching capability of 3 girls (3.55-, 4.74- and 7.06-years old), in the presence and in the absence of the model. Constant errors (CE) (estimation-real value), absolute percent errors (APE) (vertical bar 1 - estimation/real value vertical bar x 100), and error tendency (underestimations, right judgments, or overestimations) were calculated. A model and a condition effect were verified on APE. APE for the younger model were greater than for the other models (p
