Self-report data and think-aloud data from 37 undergraduates were used to examine the impact of conceptual scaffolds on self-efficacy, monitoring, and planning during learning with a commercial hypermedia environment. Participants, randomly assigned to either the No Scaffolding (NS) or Conceptual Scaffolding (CS) condition, used a hypermedia environment for 30 minutes to learn about the circula...

The planning process is central to goal-directed behaviour in any task that requires the organization of a series of actions aimed at achieving a goal. Although the planning process has been investigated thoroughly, relatively little is known about how this process emerges and evolves during childhood. In this paper we describe three reinforcement learning models of planning, in the Tower of Lo...

This study compared the effects of teacher-provided direct and indirect written corrective feedback and manipulation of resource-directing dimensions of task cognitive complexity along +/- Here and Now condition on the grammatical accuracy of Iranian intermediate EFL learners’ narrative writing tasks. There were 45 participants in the study who were randomly assigned to three experimental group...

We examine people’s strategic cognitive responses to being interrupted while performing a task. Based on memory theory, we propose that resumption of a task after interruption is facilitated by preparation during the interruption lag, or the interval between an alert to a pending interruption (e.g. the phone ringing) and the interruption proper (the ensuing conversation). To test this proposal,...

While learners’ ability to speak academic language develops over time in content-based programs, the development of their nonacademic language appears to lag behind. Students’ speaking in content-based (CB) classrooms is confined to an academic discourse style. In the researchers’ point of view, the gap of less amount of nonacademic speaking can be bridged by the application of the conceptual f...

Previous brain electrophysiological research has studied the interregional connectivity during the tapping task and found that inter-hemispheric alpha coherence was more significant under bimanual task conditions than that under unilateral conditions, but the interregional connectivity situation in the unilateral tapping condition was not explored clearly. We have designed a unilateral repetiti...

PURPOSE We analysed the cognitive influence on walking in multiple sclerosis (MS) patients, in the absence of clinical disability. METHOD A case-control study was conducted with 12 MS patients with no disability and 12 matched healthy controls. Subjects were referred for completion a timed walk test of 10 m and a 3D-kinematic analysis. Participants were instructed to walk at a comfortable spe...

GIPO IV is an experimental environment for planning domain knowledge engineering. The purpose of the tool is to demonstrate the range and scope of tools required to support the knowledge engineering aspects of planning systems creation. In particular GIPO provides support for the encoding and validation of planning domain knowledge, for both classical pre-condition planning and hierarchical pla...

The problem of planning for a robot that operates in environments containing large number objects, taking actions to move itself through the world as well change state is known task and motion (TAMP). TAMP problems contain elements discrete planning, discrete–continuous mathematical programming, continuous thus cannot be effectively addressed by any these fields directly. In this article, we de...
