Information Processing


            Information processing is receiving information through the senses, analyzing it, and making it meaningful.

            Information Processing Model  - captures the main elements of the process, from receipt of information via the senses, to outputs such as decision-making and actions.  Information processing theory is mainly developed for the process of our memory.                                IPM is used to analyze memory while receiving some information.                                            IPM captures the main elements of the process, from receipt of information via the senses, to outputs such as decision-making and actions.

 Sensory Receptors and Sensory Stores
Physical stimuli are received via the sensory receptors (eyes, ears, etc.) and stored briefly in sensory stores (sensory memory).                  
Visual information is stored for up to half a second in iconic memory and sounds are stored slightly longer (up to 2 seconds) in echoic memory.
This enables us to remember a sentence as a sentence, rather than merely as an unconnected string of isolated words, or a film as a film, rather than as a series of disjointed images.
Stage 1. Gathering information - by using our senses (sight, hearing, touch or smell),
Stage 2. Perception or Assessment
Stage 3. Evaluation and Decision-Making
Stage 4. Action and Response 
Stage 5. Feedback

Human Factor Introduction

Human Factor -  A  Person working in a maintenance environment requires human factor knowledge as per his job requirement. Human Factor Training  - Aviation safety relies on maintenance. When it is not done correctly , it may cause an incident or an accident.  Mistakes of maintenance personnel is difficult to detect. They are subjected to work in changing working in variety of adverse conditon. Regulatory Requirement : CAR 66 Module 09 Human factor - for get AMEL Human Factor   - Study of human capabilities and limitations in the workplace.   It is about study of the interaction  of maintenance personnel, the equipment used, the written and verbal procedures and  rules followed by them, and the environmental conditions of any system.  Aim of human  factors is to optimise the relationship between maintenance personnel and systems to improve  safety, efficiency, and well-being. HF - Fitting the man to the job and the job to th...

SHEL(L) Model

Model are used to understand human factor  as a framework around which human factor issues can be structured. SHEL(L),PEAR, Dirty Dozen  S - Software H - Hardware L - Liveware E - Environment                                         Liveware  is at the center of the model, is   the most critical and flexible component in the working  Environment and subject to considerable variations in performance and suffer many limitations.                           Physical size and shape.  In the design of workplace and equipment, body measurements and movements is considerd , which may vary according to factors such as age, ethnicity and gender. Human Factors inputs is provided  in the design process, and data for these inputs are available from anthropometry, biomechanics and k...

Information Processing Limitation

Human information processing  have limitations.   AMT requires support such as reference  to written material (e.g. manuals). Attention and Perception -  A proportion of ‘sensed’ data may be lost without being                              ‘perceived’.   Failing to  perceive  something  which   someone  has said to you, when you are concentrating on something else, even  though the words would have been received at the ear without any problem.  Information processing system has  ability  to perceive   something (such as a picture,                       sentence, concept, etc.) even though some of the data  may be missing.  Danger - people can fill in the gaps with  information from their own store of knowledge or experience, and this may lead to  t...
