In previous studies, causal contingencies have been suggested to play an important role in causality judgments. However, little is known about how children might use causal contingencies to inform their judgments of causality, especially under uncertainty. In the current study, we found that young children are sensitive to both conditional and unconditional causal contingencies. Furthermore, ch...

An object learning system for image understanding is proposed in this paper. The knowledge acquisition system is designed as a supervised learning task. Therefore, the role of the user as teacher of the system is emphasized, which allows to obtain the object description as well as to select the best recognition strategy for each specific object. An object description is acquired by considering ...

Microstructures of Learning: Novel methods and approaches for assessing structural and functional changes underlying knowledge acquisition in the brain The HuMeNS (Humanities, Medicine, Natural science, Social sciences) Advanced Study Group at Pufendorf Institute, Lund University is conducting an interdisciplinary research program involving collaboration between linguistics, neuroscientists, ph...

This article presents a conceptual analysis of collaboration scripts used in face-to-face and computer-mediated collaborative learning. Collaboration scripts are scaffolds that aim to improve collaboration through structuring the interactive processes between two or more learning partners. Collaboration scripts consist of at least five components: (a) learning objectives, (b) type of activities...

A knowledge acquisition study in the domain of tall building design was conducted. Domain experts, five structural engineers and one architect, were interviewed. The experts were asked a set of questions divided into design process and design content questions, and asked to simulate a design scenario. The experts were also shown, and asked to critique, a prototype implementation of a design gra...

Cognitive social capital (e.g., norms/values, trust, reciprocity), is expected to contribute to project success. However, the manner in which this occurs has not received much attention. Using data from Ghana we provide findings on the contributions of cognitive social capital to project success by way of knowledge acquisition and exploitation.

This paper presents a learnable representation for real-world planning systems. This representation is a significant extension of the ones used in the most recent systems from the Disciple family, the Disciple-Workaround system for plan generation, and the Disciple-COA system for plan critiquing. This representation is defined to support an integration of domain modeling, knowledge acquisition,...

GPS-based pedestrian navigation systems have become more and more popular in recent years. This paper reports a work in progress on investigating the differences of spatial knowledge acquisition with different interface technologies in the context of GPS-based pedestrian navigation. The acquisition of spatial knowledge based on mobile map, augmented reality, and voice is analysed and compared i...

This study investigated the influences of learning styles/preferences, prior computer skills and experience with online courses on adult learners’ knowledge acquisition in a web-based special education course. Forty-six adult learners who enrolled in a web-based special education course participated in the study. The results of the study showed that (a) learning styles/preferences had significa...

Empirical research and theoretical treatments of conceptual change have paid little attention to the distinction between knowledge and belief. The distinction implies that conceptual change involves both knowledge acquisition and belief revision, and highlights the need to consider the reasons that beliefs are held. We argue that the effects of prior beliefs on conceptual learning depends upon ...
