There are many different kinds of cognition
thinking remembering learning daydreaming decision making seeing reading writing talking
21
a state of mind where people perceive, act, and react to events around them intuitively and effortlessly.
experiential cognition
22
involves mental effort, attention, judgment, and decision-making, which can lead to new ideas and creativity.
reflective cognition
23
Cognition has also been described in terms of specific kinds of processes. These include the following:
attention perception memory learning reading, speaking, and listening
24
is central to everyday life. It enables us to cross the road without being hit by a car or bicycle, notice when someone is calling our name, and be able to text while at the same time watching TV.
attention
25
The extent to which this process is easy or difficult depends on
whether someone has clear goals and whether the information they need is salient in the environment
26
refers to how information is acquired from the environment via the five sense organs (vision, hearing, taste, smell, and touch)
perceptions
27
which relates to the awareness of the position and movement of the parts of the body through internal sensory organs (known as proprioceptors)
kinesthesia
28
involves recalling various kinds of knowledge that allow people to act appropriately.
memory
29
is closely connected with memory.
learning
30
occurs without any intention to learn.
incidental learning
31
goal-directed with the goal of being able to remember it.
intentional learning
32
this are three forms of language processing that have some similar and some different properties.
reading speaking and listening
33
is permanent while listening is transient.
written language
34
can be quicker than speaking or listening, as written text can be rapidly scanned
reading
35
requires less cognitive effort than reading or speaking.
listening
36
have difficulties understanding and recognizing written words, making it hard for them to write grammatical sentences and spell correctly.
dyslexics

this are the 4 processes involving reflective cognition.
problem solving planning reasoning decision making
38
involves working through different scenarios and deciding which is the best option or solution to a given problem.

information processing distributed cognition emboided interaction
41
are used by people when needing to reason about a technology.

describes the distance from the user to the physical system
gulf of execution

the distance from the physical system to the user.
gulf of evaluation
44
People interact with or create information by using a variety of external representations, including books, multimedia, newspapers, web pages, maps, diagrams, notes, drawings, and so on.
external cognition
45
approach to conceptualizing how the mind works has been to use metaphors and analogies to describe cognitive processes.
information processing
46
Hypotheses can be made about how long someone will take to perceive and respond to a stimulus also known as
reaction time

involve people interacting with external kinds of representations, such as books, documents, and computers and also with each other.
