Although necessary, learning to discover new solutions is often long and difficult, even for supposedly simple tasks such as counting. On the other hand, learning by imitation provides a simple way to acquire knowledge by watching other agents do. In order to learn more complex tasks by imitation than mere sequences of actions, a Think Aloud protocol is introduced, with a new neuro-symbolic net...

Thinking Aloud Thinking Aloud is the most commonly used technique used to test users ́ interaction with computers. The assumption is that Think Aloud gives access to what goes on in the users ́ minds. However, interfaces are multi modal and play heavily on user ́s visual perception. Reflecting upon Think Aloud (TA), we ask the question: what happens when users are required to verbalise their visua...

For example, a prolonged gaze to some widget does not necessarily mean that the user does not understand the meaning of the widget. The user may just be pondering some aspect of the given task unrelated to the role of the widget on which the gaze happens to dwell. Similarly, a distinctive area on a heat map is often interpreted as meaning that the area was interesting. It attracted the user’s a...

Many user-centred studies of digital libraries include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using digital libraries to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the system(s) used or understanding aspe...

In this study, we examined whether think-aloud procedures would uncover differences in the kinds of inferences generated by average and below-average readers. Participants were 40 third-grade children who were divided into groups of average and below-average readers. All participants completed measures of nonverbal IQ, reading, language, and working memory, and a story comprehension task that c...

BACKGROUND There is recognition that different data collection methods gather different aspects of decision making data. Although the selection of a method to explore nurses' decision making is partially determined by the theoretical perspective that informs each study, some flexibility remains. Description of the relative benefits of each method will enable future researchers to selectively id...
