Chapter 2 - How to Study Cognition Flashcards
algorithm
A set of operations that produces the input/output mapping of a function.
behavioral neuroscience
A scientific field that assesses behavior and neurological factors in animals as models of human function.
behaviorism
A school of psychology that emphasized using observable stimuli and behaviors as the basis of scientific experimentation.
blindsight
A phenomenon in which someone who reports blindness due to cortical damage still shows behavior consisting with some perception.
classical conditioning
A learning protocol in which an involuntary behavior is paired with a stimulus, eventually leading to that behavior being elicited by the stimulus alone
cognitive neuroscience
A scientific field that merges brain imaging with behavioral experimentation.
cognitive revolution
A movement in the 1950’s that proposed that the mind could be understood as a computational system.
cognitivism
An approach in psychology that uses behavior as a method for developing and testing theories of the underlying processing of the mind.
computational neuroscience
A scientific field that uses computer models of the brain to model real brain function.
cortical blindness
A condition in which an individual with damage to the visual cortex will report having no visual experience, despite having working eyes.
dualism
The view that the mind and body consist of fundamentally different kinds of substances or properties.
function
Mappings from inputs to outputs
human factors
A field of applied psychology concerned with the interaction between human perception and the design of systems.
idealism
The view that the only kind of reality is mental in nature.
independent variable
The conditions that are being manipulated by the experimenter in order to determine their effects on the dependent variable.
individual differences
Variations in performance across different individuals in cognitive tasks.
information processing
An approach to human cognition that views it as a type of computation with sensory information serving as an input which is processed by the brain to determine a behavioral output.
introspection
A technique employed by the structuralists to study the mind by training people to examine their own conscious experiences.
latent learning
Learning in the absence of any reward or punishment conditioning, as in Tolman’s maze experiments.
mind-body problem
The question of how mental events, such as thoughts, beliefs, and sensations, are related to physical mechanisms taking place in the body.
monism
The view that there is only one kind of basic “substance” in the world, whether exclusively physical or exclusively mental.
neutral monism
The view that the mental and physical are identical and all of reality is made of this one kind of thing.
operant conditioning
A method of conditioning that reinforces certain behaviors through a system of rewards and punishments.
opsin
Light-activated proteins, used in optogenetics to experimentally modify the activity of neurons.
optogenetics
A technique used to control the activity of brain cells based on introducing light-sensitive proteins into the cells and activating them with light.
physicalism/materialism
The view that all of reality, including mental processes, is physical or material in nature.
reaction time
A measure of how long it takes an experimental subject to respond to a given task or query.
reinforcement learning
A form of behavioral conditioning based on punishment and reinforcement (reward) feedback.
replication
A process in scientific research in which a previous experiment is repeated using the same methods as the original.
response
The behavior an experimental subject engages in after a stimulus is presented.
Skinner box
A chamber used to contain and automatically provide behavioral feedback to an animal during operant conditioning experiments.
speed-accuracy tradeoff
When a participant in an experiment sacrifices accuracy in their responses for greater speed or vice-versa.
subject/participant (experimental)
A person upon whom a psychological experiment is being conducted.
stimulus
Anything used to stimulate the senses as part of an experimental procedure, such as an image or a sound.
