Human behavior is learning how humans capture & process the information they receive & how they physically manipulate objects to reach their goals.

Information processing is divided into 3 categories:

With the increase in usage of Graphical User Interface (GUI) in computer systems is an advantage to the visually impaired.

A written form such as the use of email or instant messaging can be used to improve communication between those with hearing impairment.

For those with physical impairments, using a mouse to interact with the system will be easier for them.

Although one of the solutions for those with speech impairment is the use of textual communication, this method can be slow and lower efficiency during the communication.

Cognitive process is concerned with how we acquire experience, and how we store experience in our long term memory.

Memory is appropriately divided into :

Explicit memory is associated with consciousness and divided again into the memory of events (episodic memory) and the memory for words, rules and language, etc (semantic memory).

Implicit memory does not involve awareness. It includes among other things, skills, habits and conditioned reflexes.

Sensory memory is the capacity for holding, but not manipulating, a small amount of information in mind in an active, readily available state for a short period of time.

The two types of sensory memory that have been most explored are :

i. explicit

ii. iconic

iii. implicit

iv. echoic

Iconic Memory, the auditory version of sensory memory, refers to the phenomenon in which there is a brief mental echo that continues to sound after auditory stimuli has been heard.

Distribution of practice effect means that it takes time to learn. Hence, learning cannot be rushed if you want the information to be stored long term.

Recall requires you to have experience or to have seen a similar situation beforehand.

Decay is due to lack of rehearsal and after a long period of time, this information started to fade from the long-term memory.
