Introduction to Cognitive Models
cognitive models serve as conceptual frameworks that
help us comprehend and represent the intricate
processes that occur within the human mind. At their
core, these models aim to decode how individuals
acquire, process, store, and utilize information. By
examining cognitive models, we gain valuable insights
into the mechanisms underlying human learning,
problem-solving, and decision-making.
These models are essential bridges between the realms
of psychology and technology. They enable researchers,
educators, and practitioners to explore the complexities
of mental processes in a systematic manner. Cognitive
models are not only theoretical constructs but also
practical tools that find applications in diverse fields.

Understanding the user's
behaviour and cognitive difficulty

between user and system.
Based on empirical
knowledge of human
motor system
All of these cognitive models make
assumptions about the architecture
the human mind.

Applicationof Cognitive Models
Cognitive models inspire AI
algorithms.
Mimicking human cognition
enhances AI's ability to
learn, reason, and adapt.
UX designers utilize cognitive
models to enhance product
usability.
Aligning interfaces with users'
cognitive abilities improves
overall satisfaction.
Cognitive models are
applied to assess and
mitigate risks.
Understanding decision-
making processes helps
enhance security measures.

Organisational factors can make or break a
system
Studying the work group is not sufficient
•any system is used within a wider context
•and the crucial people need not be direct
users
Before installing a new system must understand:
•who benefits
•who puts in effort
the balance of power in the organisation
… and how it will be affected
Even when a system is successful
… it may be difficult to measure that success
Organisational issues

Conflict and power
CSCW = computer supported cooperative
work
people and groups have conflicting goals
systems assuming cooperation will fail!
e.g. computerise stock control
stockman looses control of information
subverts the system

but need to know that is
what we are doing
and more often an
accident !
Employees want to understand their job
responsibilities, whom they report to, what
decisions they can and should make and how they
interact with other people and teams within the
company. An organizational structure creates this
framework. Organizational structures can be
centralized or decentralized, hierarchical or
circular, flat or vertical.

Centralized vs. Decentralized
Many companies use the traditional model of a centralized organizational
structure. With centralized leadership, there is a transparent chain of
command and each role has well-defined responsibilities.
Conversely, with a decentralized organizational structure, teams have more
autonomy to make decisions and there may be cross-collaboration between
groups. Decentralized leadership can help companies remain agile and
adapt to changing needs..
Hierarchical vs. Circular
Example Text : Get a modern PowerPoint Presentation that is beautifully designed. A
hierarchical organization structure is the pyramid-shaped organization chart many
people are used to seeing. There is one role at the top of the pyramid and the chain of
command moves down, with each level decreasing in responsibilities and authority.
On the other hand, a circular organization chart looks like concentric circles with
company leadership in the center circle. Instead of information flowing down to the
next “level,” information flows out to the next ring of management.
Vertical vs. Flat
A vertical organizational chart has a clear chain of command with a small
group of leaders at the top—or in the center, in the case of a circular
structure—and each subsequent tier has less authority and responsibility.

4 Common Types of Organizational Structures
A functional—or role-based—
structure is one of the most
common organizational
structures. This structure has
centralized leadership and the
vertical, hierarchical structure
has clearly defined roles, job
functions, chains of command
and decision-making authority.
Functional/Role-
Based Structure
01
The geographical
structure is a good option
for companies with a
broad geographic
footprint in an industry
where it is essential to be
close to their customers
and suppliers.
Geographical Structure
03
Along with the functional
structure, the product- or
market-based structure is
hierarchical, vertical and
centralized. However, instead
of being structured around
typical roles and job functions,
it is structured around the
company’s products or markets.
Product- or Market-
Based Structure
02
Similar to the
functional structure,
the process-based
structure is
structured in a way
that follows a
product’s or service’s
life cycle. .
Process-Based Structure

interests
•stakeholder is anyone
effected by success or
failure of system
•designers need to

stakeholder needs as
possible

organization's goals,
constraints, and the rationale
behind decisions.
Mediation and Resolution:
If conflicts persist, consider
third-party mediation or
resolution mechanisms.

Communication Models
Communication models are conceptual frameworks
that help us understand and describe the process of
communication. These models depict the elements
and dynamics involved in the exchange of information
between a sender and a receiver. They serve as
simplified representations of real-world communication,
aiding in the analysis and improvement of
communication processes.

Lasswell’sModel
Linear Lasswell’smodel is a basic framework for
analyzing one-way communication by asking five
questions: Who, said what, through which channel,
to whom, with what effects?
Shannon-Weaver Model
Linear The Shannon-Weaver model is the first to highlight
the role of ‘noise’ in communication, which can
disrupt or alter a message between sender and
receiver.
Berlo’sS-M-C-R Model Linear Berlo’sS-M-C-R model explains communication in
four steps: Source, Message, Channel, and
Receiver.
Osgood-Schramm Model Interactive The Osgood-Schramm model looks at reciprocal
communication, showing how we have to encode,
decode, and interpret information in real-time
during a conversation.
Westley and Maclean Model Interactive The Westley and Maclean model shows that our
communication is influenced by environmental,
cultural and personal factors.
Barnlund’sTransactional Model Transactional Barnlund’sTransactional Model of Communication
highlights the role of private and public cues that
impact our messages.
Communication Models

With the advent of technology, collaboration models
often incorporate the role of digital tools and
platforms. Virtual collaboration, cloud-based
communication, and collaborative software play a
significant role in modern collaboration models.
Technology Integration
05
Collaboration models address decision-making
processes within a team. This includes methods
for reaching consensus, resolving conflicts, and
ensuring that decisions align with the collective
goals..
Decision-Making Processes
04
Many collaboration models involve interdisciplinary
cooperation, where individuals from different
backgrounds, expertise, and disciplines come
together to contribute their unique perspectives
and skills..
Interdisciplinary Cooperation
03
Communication is a cornerstone of collaboration.
Models highlight the need for transparent and
open communication channels, ensuring that
information flows seamlessly between
collaborators..
Effective Communication
02
Collaboration models emphasize the importance of
establishing clear and shared goals. All collaborators
should be aligned with the overarching objectives to
work towards a common purpose..
Shared Goals and Objectives
01
Collaboration models are
conceptual frameworks that
illustrate how individuals,
teams, or organizations work
together to achieve common
goals. These models
emphasize the dynamics of
cooperation,
communication, and
coordination in a
collaborative environment.
Collaboration is increasingly
crucial in today's
interconnected and
globalized world, where
teams often span
geographical locations and
diverse expertise.
