This paper presents a continuing studies of the human cognitive aspects application in the technical systems. The last studies design a human-centered design based on the German culture and the result show a difference significant of human performance between German and Indonesian. Therefore, this study examines the human cognitive model based on Indonesian culture to investigate whether the different cognitive model based on culture aspect affects the human performance. The study was conducted on 60 people classified by age, young (16-34 years old) and old (> 34 years old). Participants render predictions on assembly activity for two interim states of two different types of products which are the Builderific brick and the Pulley Release based on four types assembly model (Reference, Combination, Human Behavior 1, and Human Behavior 2). The dependent variables are prediction time, mental workload and predictive accuracy. The results show that the models of robot behavior and the products have significant influences on mental workload and predictive capability. The age variable significantly influences mental workload, performance and prediction capabilities.
