Perspectives on Cognitive Task Analysis - Robert R. Hoffman - Bog - Taylor & Francis Ltd - Plusbog.dk

Perspectives on Cognitive Task Analysis - Robert R. Hoffman - Bog - Taylor & Francis Ltd - Plusbog.dk

This volume is the first comprehensive history of task analysis, charting its origins from the earliest applied psychology through to modern forms of task analysis that focus on the study of cognitive work. Through this detailed historical analysis, it is made apparent how task analysis has always been cognitive. Chapters cover the histories, key ideas, and contributions to methodology of a number of communities of practice, including: Sociotechnics, European Work Analysis, Naturalistic Decision Making, Cognitive Systems Engineering, Ethnography, Human Factors. Further, integrative chapters focus on the purposes of cognitive task analysis. It is shown how all the various communities of practice are living in the same scientific universe, though are in many ways distinctive in terms of their key concerns and main theories. It is a historiography of task analysis, and the people who invented task analysis. It is also an explanatory primer on what cognitive task analysis is all about and what it can do. Perspectives on Cognitive Task Analyis will be of value to professionals in allied disciplines who might come to rely on cognitive task analysis in their system development programs. It will be invaluable to students who need to know what task analysis and cognitive task analysis are really all about. For practitioners of cognitive task analysis, this volume is a major presentation of what their scientific universe is all about.

Task Intelligence for Search and Recommendation - Chirag Shah - Bog - Springer International Publishing AG - Plusbog.dk

Task Intelligence for Search and Recommendation - Chirag Shah - Bog - Springer International Publishing AG - Plusbog.dk

While great strides have been made in the field of search and recommendation, there are still challenges and opportunities to address information access issues that involve solving tasks and accomplishing goals for a wide variety of users. Specifically, we lack intelligent systems that can detect not only the request an individual is making (what), but also understand and utilize the intention (why) and strategies (how) while providing information and enabling task completion. Many scholars in the fields of information retrieval, recommender systems, productivity (especially in task management and time management), and artificial intelligence have recognized the importance of extracting and understanding people''s tasks and the intentions behind performing those tasks in order to serve them better. However, we are still struggling to support them in task completion, e.g., in search and assistance, and it has been challenging to move beyond single-query or single-turn interactions. The proliferation of intelligent agents has unlocked new modalities for interacting with information, but these agents will need to be able to work understanding current and future contexts and assist users at task level. This book will focus on task intelligence in the context of search and recommendation. Chapter 1 introduces readers to the issues of detecting, understanding, and using task and task-related information in an information episode (with or without active searching). This is followed by presenting several prominent ideas and frameworks about how tasks are conceptualized and represented in Chapter 2. In Chapter 3, the narrative moves to showing how task type relates to user behaviors and search intentions. A task can be explicitly expressed in some cases, such as in a to-do application, but often it is unexpressed. Chapter 4 covers these two scenarios with several related works and case studies. Chapter 5 shows how task knowledge and task models can contribute to addressing emerging retrieval and recommendation problems. Chapter 6 covers evaluation methodologies and metrics for task-based systems, with relevant case studies to demonstrate their uses. Finally, the book concludes in Chapter 7, with ideas for future directions in this important research area.

Powerful Task Design - Terri Ann Stice - Bog - SAGE Publications Inc - Plusbog.dk

Powerful Task Design - Terri Ann Stice - Bog - SAGE Publications Inc - Plusbog.dk

How can educators use technology to increase students’ engagement in activities essential to rigorous learning? What are the most effective tools for analyzing, designing, and refining those tasks of learning? And finally, how can we increase the cognitive rigor and thoughtful integration of technology into learning tasks, in order to better prepare students for college and beyond? In Powerful Task Design, these questions and more will be answered, as you get to know the Powerful Task Rubric for Designing Student Work. Applicable for educators across all disciplines and grade levels, you’ll use the tool to analyze, design, and refine cognitively engaging tasks of learning. This guide will help you - - Explore and use the Powerful Task Rubric piece-by-piece in an easily digestible format to help you delve into the tool’s design components. - - Use technology to complete interactive tasks, and understand first-hand how technology is a critical design component in student task design that brings about more profound and relevant learning. - - Identify opportunities for creating powerful tasks in the areas of engagement, academic strategies, questions, and cognition. - - Supplement your task design arsenal with tools like the Diagnostic Instrument to Analyze Learning (DIAL). - This must-have resource brings together the research and strategies educators need to design engaging, powerful learning tasks. Student performance has a direct correlation to the power of the learning task - this book will help you positively impact both.

Integrative Views on Dual-task Costs - - Bog - Taylor & Francis Ltd - Plusbog.dk

Integrative Views on Dual-task Costs - - Bog - Taylor & Francis Ltd - Plusbog.dk

It is well known that the capacity for both simultaneous and rapid sequential information processing is limited. In the past two decades, at least four different approaches for the investigation and explanation of dual-task interference have developed. Surprisingly, these developments have taken place largely independent of each other. For example, working memory theories explain the inability to memorize combinations of data with the existence of modality-specific memory storage. Task switching models attribute switch costs to a combination of task reconfiguration costs and interference between competing task sets. Research with the refractory period paradigm suggests that a second of two responses is slowed because demanding processes such as response decisions defy parallel processing. Finally, attentional blink research shows that limited awareness of the second of two masked visual targets is caused by storage difficulties during the identification of the first target. The rare attempts at finding bridges between dual-task models attribute the costs to a mixture of shared and unique mechanisms. The ten papers gathered in this issue address questions such as: What is the relationship between working memory storage, retrieval, and cognitive operations? Can control processes account for the attentional blink and the refractory period effect? Are capacity limitations modality specific, and are they triggered by bottom-up or top-down processes? The authors argue that goal adjustments and episodic encoding of events qualify as shared mechanisms underlying dual-task limitations across multiple paradigms.
