IB: Cognitive approaches

History
• Taylor (1968) : 使用者沒有完整的世界圖像,即對資訊的需求、
  意義與價值乃立基於個人的認知觀點。
• Dervin & Nilan (1986) 鼓吹並揚棄系統取向

何謂認知
• Belkin: 人類(或資訊處理機制)在接受/感知或生產時,如何運
  作(或互動)知識、信念、等等
• Scope (Pettigrew, et.al., 2001)
  • 關於個人如何應用他自我世界的觀點或模型,處理資訊的需求、
    搜尋、給出、與使用的研究
IB: Social approaches

History
• 從1990年代初期慢慢興起,並變得越來越重要
• Chatman (80s-) 開始研究貧窮勞工階級的資訊行為

何謂社會取向
• 資訊的意義與價值,與其社會脈絡相關
• 偏向以自然探究, 人類學或社會學的方法進行研究
IB: Multifaceted (Multidimensional) approaches

• 由於了解到人類資訊行為的複雜性,越來越多研究者認為需
  要以多元觀點進行研究,而非只考慮認知的與社會的一種觀

• 認知工作分析 (CWA)是由 Rasmussen, Pejtersen, Goodstein
  (1994)所共同發展出來的一種研究概念架構

Cognitive Work Analysis

• 認知工作分析實際上與認知科學並沒有直接關係,根據
  Rasmussen(1994),其理論依據來自於:
  • 系統化思維(General System Thinking)
  • 適應控制系統(Adaptive Control Systems)
  • Gibson的環境心理學(Ecological Psychology)


• 重點:限制(constraint) 與 適應(adaptive)
• CWA 認為,在與工作相關的活動中進行資訊互動的人,是一
  行動者/演員(actor) ,而非一般資訊系統所稱的使用者(user)

CWA 認為,在與工作相關的活動中進行資
訊互動的人,是一「行動者/演員(actor)」,
而非一般資訊系統所稱的「使用者(user)」


理論基礎是:
  系統化思維(general system thinking)
  適應控制系統(adaptive control
  systems)
  Gibson的環境心理學(Ecological
  Psychology);
  以及各種不同工作領域中支援系統開發
  的實地研究。

Challenges to the CIR process

Actors 對行為者而言,CIR的挑戰是:
• 需要花時間討論
  Spend time in discussions

• 不同行為者,在CIR過程中有不同的立場。
  Difference actors have different stakes in the process, or have different priorities

• CIR中成員的理解不同
  The understanding of problems might various

• 新手需邀請專家參與
  Notice involve other expert actors

• 討論或協作中會發生資訊過載
  Information overload
Discussion

Multiple dimensions
  Such interdependencies suggest that focusing on a single
  dimension may not only provide a partial understanding, but
  might also be misleading.

Microsoft HSC Design Team: Environments • Microsoft Corporation • Products & Projects: Help & Support Center • Project division: Test, Development, Program Management, and Design • Design Team: Product Designer, Visual Designer, Usability Engineer, Project Manager • Task: The Case of Navigation Design Work Environment Work Domain Analysis Task Analysis Organizational Analysis
  • 28. Actors: a product designer & his colleagues • Neil, the product design lead • Resources: colleagues • Artifacts: to-do list, prototype, previous system • Task Goals & Priorities: provide a high-quality design, fit user behavior and user preferences • Environment constraint: Work Environment Work Domain limited time, Analysis Task ensure coordinated with other teams Analysis Organizational Analysis Strategy • Strategies: Neil find used navigation model
  • 29. Actors: Decision Ladder • Spent all time between analysis - evaluation • Decision making did not share with his colleagues • 3rd phase (planning) did not involve CIR Work Environment Work Domain Analysis Task Analysis Decision Organizational Analysis Strategy Neil Notice: CIR(Collaborative Information Retrieval) doesn’t include action-taking behavior (?)
  • 30. CIR: Motives: Cognitive • Inexperience: Novice to Microsoft (need personal network, Work previous system, interpretations) • Value: The quality of Environment design decision making Work Domain Analysis Task Analysis (need references, informal feedback to their ideas, and opinions) Decision Strategy • Knowledge: lack of web Organizational design tacit knowledge Analysis Neil (need Nail & Lily’s knowledge & Product designer interpretation) • Drawback-of-CIR: information overload
  • 31. CIR: Organization of the Team’s Work Define Organizational Task: • Organizational Constraint • Actor’s responsibility Work Environment Work Domain Analysis • Collaboration with others Task Analysis Decision Microsoft Culture Strategy • the boundaries of the task Organizational Analysis Neil Product responsibility are not designer always clear • Not documented • Rely on their own personal network
  • 32. CIR: Task and Decision Task: (strategy & decision) • Search for design Work Environment constraints (access sources) Work Domain Analysis • decision making of Task Analysis navigation design (no formal design guide) Decision Strategy • Prepare for Organizational communication with Analysis Neil Product others (quality) designer • Collaborative creative (quality) • Drawback-of-CIR: no creation & innovation
  • 33. Challenges to the CIR process Actors 對行為者而言,CIR的挑戰是: • 需要花時間討論 Spend time in discussions • 不同行為者,在CIR過程中有不同的立場。 Difference actors have different stakes in the process, or have different priorities • CIR中成員的理解不同 The understanding of problems might various • 新手需邀請專家參與 Notice involve other expert actors • 討論或協作中會發生資訊過載 Information overload
  • 34. Discussion Multiple dimensions Such interdependencies suggest that focusing on a single dimension may not only provide a partial understanding, but might also be misleading. Contributions to the Study of CIR Notice: The goals of CWA research? What the difference between CWA & IB research?
