This paper focuses on the effects of activating expected self as compared to the effects of activating the ought self. The expected self is a component of self-knowledge that pertains to the perception of one's capabilities and potentials. Two experimental studies compared participants' task performance after manipulating the momentary accessibility of the expected self vs. the ought self. In S...

This paper describes a prototype of a simulaled physics student that learns by interacting with a human tutor. The system solves physics problems while showing its work on a work· station screen, and the tutor can intervene at cenain points during problem·solving to advise the simulaled studenL This prototype constitutes an initial cognitive task analysis of the skill of learning from a tutor, ...

The apparent difficulty that humans experience when asked to manage dynamic complexity might be related to their inability to discriminate among familiar classes of objects (i.e., flawed recognition). In this study we examined the change in individuals’ recognition ability, as measured by the change in the similarity of decisions they made when confronted repeatedly with consistent dynamic situ...

the present study was conducted to compare the effect of individual and group pre-task planning on efl learners’ accuracy and complexity in speaking. to fulfill the purpose of the study, 60 intermediate female learners at the first grade of high school were chosen by means of a sample preliminary english test (pet) and randomly divided into two experimental groups of 30 students; the individual...

This paper summarizes a model of interaction for CVEs inspired by the process followed in human communication in the real world, detailing both the main elements and the communication process itself. The model proposed copies some properties of the real world communication but also allows the easy integration of Task Analysis to the design of CVEs, helping the developer in the design of the app...

In this paper, an integrated framework for knowledge audit and capture using the task analysis approach is presented. We first identify the types of knowledge that could be ascribed to tasks and analyze a task by breaking it down into subtasks and task elements. We then identify the skills and knowledge required to perform the tasks at this level. The framework is validated and tested on an exp...

For today's increasingly power-constrained multicore systems, integrating simpler and more energy-e±cient in-order cores becomes attractive. However, since in-order processors lack complex hardware support for tolerating long-latency memory accesses, developing compiler technologies to hide such latencies becomes critical. Compiler-directed prefetching has been demonstrated e®ective on some app...

In this paper, we describe our experience with developing Airshed, a large pollution modeling application, in the Fx programming environment. We demonstrate that high level parallel programming languages like Fx and High Performance Fortran offer a simple and attractive model for developing portable and efficient parallel applications. Performance results are presented for the Airshed applicati...
