Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Concepts and Prototypes01:24

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...
Natural and Artificial Concepts01:24

Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint Vincent in...
Communication01:28

Communication

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Communication01:03

Communication

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.
Understanding Memory01:19

Understanding Memory

Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

Summary

This study clarifies the concept of information need, defining it as a desire for information shared by professionals. Understanding information needs is crucial for effective healthcare and coping behaviors.

Area of Science:

  • Health Informatics
  • Information Science
  • Communication Studies

Background:

  • The concept of 'information need' is widely used in healthcare and research but lacks clear definition.
  • Current literature shows limited understanding and consistent definitions of information needs.
  • Healthcare is increasingly framed as 'needs-based', highlighting the importance of this construct.

Purpose of the Study:

  • To explore and clarify the concept of 'information need' through rigorous concept analysis.
  • To provide a clearer, more consistent definition of information need for academic and practical use.
  • To address the ubiquitous use of the term with inconsistent definitions in various fields.

Main Methods:

  • Utilized Rodgers' evolutionary approach to concept analysis.

  • Identified common attributes, antecedents, and consequences of 'information need'.
  • Analyzed the subjective nature of contemporary information needs and their role in coping.

    • Main Results:

    • Information need is defined as a desire for information, facilitated by professional communication skills.
    • Information-seeking behavior is triggered by stimuli perceived as challenges or threats.
    • The study highlights the subjective and context-dependent nature of information needs.

    Conclusions:

    • Conceptual clarification of 'information need' is essential for advancing research and practice.
    • A clearer definition can guide studies on the subjective aspects of information needs and coping mechanisms.
    • This analysis provides a foundation for future research into information needs in diverse populations and contexts.
