Title: The Cognitive Level of Analysis
1The Cognitive Level of Analysis
2Objective 1.2Explain how principles that define
the cognitive level of analysis
3Principles that define the cognitive level of
analysis
- 1. Our physiological processes (such as the
physical brain, neurotransmission, etc.) give
rise to cognitive processes (such as language,
memory, decision making, perception, learning,
etc.) - 2. Models of mental processes can be proposed and
investigated scientifically - 3. Cognitive processes are influenced by social
and cultural factors
41. Our physiological processes give rise to
cognitive processes.
51. Our physiological processes give rise to
cognitive processes.
- In other words, specific parts of the brain can
directly correlate to cognitive processes. - Damage to the frontal lobe can directly affect
the cognitive process of decision making
61. Our physiological processes give rise to
cognitive processes.
- Damage to the hippocampus can directly affect the
cognitive process of short term memory
71. Our physiological processes give rise to
cognitive processes.
- Damage to Brocas area can directly affect the
cognitive process of language production
81. Our physiological processes give rise to
cognitive processes.
- All of our mental processes are physiologically
based. Thus, we can better understand cognitive
processes by understanding the physiological
processes that give rise to cognitive processes. - Thus, this principle may be demonstrated in
research by observing how deficits in cognitive
processes correlate to specific physiological
processes.
92. Models of mental processes can be proposed and
investigated scientifically
- Cognitive processes are difficult to study. They
often occur rapidly, and inside the mind so they
cannot be observed directly. - It is only the responses that participants make
when given some cognitive task to perform that
can tell us about cognitive processes. - These tasks usually take place under tightly
controlled lab experiments where the main aim is
to isolate a particular component of the
cognitive process for the study. (This can be
used to assist you with objective 1.2)
101. Our physiological processes give rise to
cognitive processes.
- Ethically, since we cannot create these lesions
in humans, we must either create lesions with
animal models or study cases of the specific
lesion. - One specific case example is the case of Clive
Wearing - Watch for yourself!

111. How the study demonstrates the principle
- By studying the physiological origins of
cognitive processes, we are able to conclude that
specific processes (in this example The
Hippocampus) directly effect the cognitive
process of memory.
122. Models of mental processes can be proposed
(through theory) and investigated scientifically
(through lab experiments)
- By creating models of cognitive processes, we are
able to isolate theses processes (through
laboratory experiments) to see how various
environmental factors influence them. - In summation, models of cognitive theories allow
us to empirically investigate the cognitive
products of our physiological processes.
132. Models of mental processes can be proposed
(through theory) and investigated scientifically
(through lab experiments)
- Thus, this principle may be demonstrated in
research by empirically studying cognitive models
in order examine their causes and influences. - One example is the research experiment conducted
by John Ridley Stroop
142. Models of mental processes can be proposed
(through theory) and investigated scientifically
(through lab experiments)
- The Stroop Effect is an effect found in the 1930s
by John Ridley Stroop. - This effect is a model for how our brain
processes information. This effect demonstrates
how interference can slow down how the brain
processes information because it is trying to
sort various things at the same time.
152. Models of mental processes can be proposed
(through theory) and investigated scientifically
(through lab experiments)
- The Stroop Test is considered to measure
selective attention, cognitive flexibility and
processing speed, and it is used as a tool in the
evaluation of executive functions (activities
such as planning, organizing, strategizing,
paying attention to and remembering details, and
managing time and space).

202. Models of mental processes can be proposed
(through theory) and investigated scientifically
(through lab experiments)
- You may find that you hesitate or stumble,
because the brain is trying to pay attention to
more than one thing, reading and the visualizing
the colors. - The brain tries to process two types of
information a color, and a word naming a color.
This is why it is much more difficult to read the
second set of words. - This study demonstrates that cognitive models
(such as attention processing) can be
investigated through scientific methods (such as
with an experiment)
21Principle 3Cognitive processes are influenced
by social and cultural factors
- That is, our memories, learning, language,
perception, decisions, etc. can be influenced by
our culture and by environmental factors. -
- This principle may b e demonstrated in research
that looks at social and cultural influences on
cognitive processes.
22Principle 3Cognitive processes are influenced
by social and cultural factors
- Frederic Bartletts study demonstrates how memory
can be distorted by cultural schemas. - Schemas are representations of knowledge based on
experience. In his study in which British
participants were asked to recall a native
American folktale.
23Principle 3Cognitive processes are influenced
by social and cultural factors
- He found that the story of The War of the
Ghosts was difficult for Western people to
reproduce exactly because of its cultural content
which was unfamiliar to them. - The participants ended up encoding the meaning of
the story adapted to their existing cultural
schemas.
24Principle 3Cognitive processes are influenced
by social and cultural factors
- As a result, Bartlett concluded that cultural
interpretation plays a large role in remembering
events or stories. - By showing the cultural context of our schemas
(organized memories), Bartlett was able to show
the cultural influence on our cognitions.
