Cognition Exam 1
Who conducted studies of the cognitive approach?
Donders (1868)
The measurement of the cognitive approach is:
Reaction time
The use of introspection was a hallmark method of which school of psychology?
Structuralism
True or False: The school of behavioralism did not focus on beliefs, planning, and goals.
True
Computer:
a model for human mental processing
Why did the idea of introspection fail?
1) data can be studied by one individual (problem arises bc people describe things different ways) 2) data is not measurable- cant be replicated (experiments using the same methods should get the same verifiable results) 3) only accesses mental activity that is available to conscious awareness and much of our brain activity takes place outside of awareness (ex, people with cortical blindness can guess where the visual field is although it is a guess
What was a limitation on behaviorism?
1. Cant account for new intelligence 2. latent learning
How many neurons is the brain estimated to have?
100 billion, 7000 connections each
What is physicalism/materialism?
A type of monism with beliefs that only physical matter exists
What is idealism?
A type of monism with beliefs that only the mind exists
What is the contemporary scientific thought?
An Intelligent behavior, a product of the brain, may be understood in the terms of workings of the physical brain (ex, neural monism)
Consider the following scenario. An intergalactic team of psychologists discovers a planet with robot-like androids and is trying to understand them. Which school of psychology does a researcher probably belong to if he/she uses the following research method? Method 1: Determine the action responses of the robots in response to specific kinds of stimulation
Behaviorist
Two parts of nervous system?
CNS and PNS
Consider the following scenario. An intergalactic team of psychologists discovers a planet with robot-like androids and is trying to understand them. Which school of psychology does a researcher probably belong to if he/she uses the following research method? Method 3: Using the response of the robot to specific kinds of stimulation in order to infer its internal mental processes
Cognitive
Descartes articulated the perspective of ______________
Dualism
What belief did the Mind-Body Problem influence people to believe?
Dualsim
True or False: Pavlov's experiment required attribution of mental states of the dog, like it thing about food.
False, entirely based on stimulus (food + bell) and response (salvation)
True or False: According to dualism, the mind and the body are no longer separate kinds of entities and the nature of their interaction is not well explained.
False, the bind and body are still believed to be separate entities by dualists
True or False: In the nature vs nurture debate, behaviorists such as Watson were strongly on the nature side.
False, they were on the nurture side because they believed behavior was learned and caould be modified
Sulcus/Sulci is...
Groove sinking in
Who founded the school of behaviorism?
John B. Watson
How do we study the brain on a macroscopic level? And microscopic level?
Macroscopic- what parts make up the brain Microscopic- understanding how neurons compute function
Why not study neuroscience to understand cognition?
Multiple reasons being 1) the brain is too complex to measure 2) neuroscience studies the physical and nervous system and 3) cognitive psychology studies the OUTCOME of the nervous system (aka behavior)
How did Pavlov study classical conditioning?
Noticed that dogs salivated at the sight of food. By stimultaneously ring a bell while the dog salivated, the dog eventually responded by salivating to the bell in the absence of food since it was conditioned.
What was the main idea of Structuralism?
Observing the mind directly
What experiment gave rise to the idea of behaviorism?
Pavlov's classical conditioning
Who articulated the idea of dualism?
Plato (350 BC), who argued that the mind was based off the immortal soul
What are the three pillars (aka aims of research) of studying cognition?
Psychology, Neuroscience, and Artificial Intelligence
What did Tolman propose from his latent learning experiment with rats?
Rats formed an internal cognitive map of the maze the initial exploration of thew maze that was accessed later for reward
Wernicke's aphasia...
Receptive aphasia -affects comprehension, not production

Ridge sticking out
What were the historical approaches to studying the brain?
Structuralism, Behaviorism, and Cognitive Approach "cognitivism"
Consider the following scenario. An intergalactic team of psychologists discovers a planet with robot-like androids and is trying to understand them. Which school of psychology does a researcher probably belong to if he/she uses the following research method? Method 2: Asking the robots to verbally report on their internal processes
Structuralist
What experiment did Watson perform?
The Little Albert Experiment
What is the most extraordinary/sophisticated computing device in the world?
The brain!
What is the largest part of the brain and what is it responsible for?
The cerebrum which is responsible for Thought, Language, Senses Memory, Voluntary movement
What is neural monism?
The idea that the mind and body are the same thing
What is dualism?
The idea that the mind and body consists of fundamentally different kinds of substances or properties. In this view the mind was NOT made of physical material
What is monism and what subsets does it contain?
The idea that there is only one kind of basic "substance" in the world. The subsets are physicalism/materialism, idealism, or neural monism.
The puzzle of how the physical body is related to mental activity is called:
The mind-body problem
Who was accountable for the latent learning example?
Tolman
True or False: An important idea of these conditioning experiments is that behavior is learned rather than depending on inborn
True
True or False: Looking within oneself to assess one's mental activity was the idea behind the school of structuralism.
True
True or False: Much recent progress has been based on computer programs modeled on the brain, known as artificial brains or neural networks, because they are based on learning rather than being programmed.
True
True or False: Skinner claimed ALL behaviors could be explained based on the combination of classical and operant conditioning.
True, in other words people learn which behaviors to produce in any situation based on the reinforcement they received for producing those behaviors in the past
Who founded the school of structuralism?
Wilhelm Wundt
What was the idea behind the Little Albert Experiment?
a young child could be classically conditioned to respond to something with great fear and anxiety after experiments, even if the child initially had no fear
What is Cognition?
acquiring and processing information about the world in order to make behavioral decisions
What is Classical Conditioning?
an involuntary behavior can be induced by a stimulus that wouldn't normally cause a reaction which changes the involuntary behavior based on feedback
What is the Cognitive approach method?
based on ideas we can measure objective behavior in order to test theories of underlying mental processes "Study behavior to make inferences about the mind"
fmri
better spatial -measures blood flow
EEG...
better temporal, bad spatial -measures electrical activity
What approaches were tested/thought of when studying cognition?
brain, behavior, and mental states (aka subjective experiences)
How did Donders carry out his study?
by comparing the time to detect a signal vs the time to decide between two signals
What is operant conditioning?
change voluntary behavior based on stimuls- response feedback
What field of science served as an inspiration to the Structuralist school?
chemistry
The Little Albert experiment was an example of...
classical conditioning
What is the idea of Cognitive Revolution:
cognition can be viewed as an input with sensory information serving as the input and a decision or behavior serving as the output (information processing happens between)
What are everyday examples of AI that we use or come in contact with?
computer vision, speech recognition, and autonomous control
Two hemispheres connected by....
corpus callosum
The underlying process of the cognitive approach is:
decision (ex- detection conditioning, discrimination condition, and choice condition)
Positive punishment example:
electric shock for lever push
What parts does the PNS contain?
everything other than the retina, spinal cord, and brain
Brocas Aphasia is....
expressive aphasia -affects production, not comprehension
Which of these methods is NOT currently considered a scientifically valid form of data for the study of cognition?
introspection
What is unique about the stimulus and response method from the school of behavioralist?
it almost completely lacked the understanding of how the brain functioned because only the stimulus and response were worthy of studying
What is latent learning? Example?
learning in the absence of any conditioning (ex- rat placed in maze to explore then placed in different start area to find hidden food)
Function:
mapping between one set of objects and another
Algorithim:
method for producing the correct output from the inout
What is the artificial intelligence arm of cognition concerned with?
models and simulations with developments that allow comoputers to be programmed to learn via artificial neural networks
What is the nervous system?
nerves and cells throughout the body whose job is to receive and transmit information from one part of the body to another (gather--> send info---->execute decision)
Teaching a dog to 'shake hands' on command using a food reward is an example of:
operant conditioning
How did Skinner test his theory of operant conditioning?
placing a mouse within a "Skinner box" which included a lever which could dispense food (reinforcement) or charged electric grid (punishment) when they pressed it. Over time, the lat learned which behaviors were rewarded and punished and chooses actions accordingly.
What was the method of structuralism?
practitioners were trained to carefully consider and describe their own internal experiences in the term of basic "elements" of consciousness
What did the school of behavioralism focus on?
reaction against the unobservable results from introspection by using stimulus and response experiments

talking, listening, navigating, remembering, playing, working, etc
Why was Skinner important in the school of behaviorism?
tested if voluntary behaviors could be changed by conditioning by teaching things to engage in behavior or reinforcing that behavior
What is response?
the behavior that the subject engages in after the stimulus is presented
What was the Mind-Body Problem?

What is Cognitive psychology?
the study of mental processes underlying intelligent behavior
