Chapter 1 Flashcards
The “crisis in psychology”.
The experimental method of experimental psychology began to be applied to a larger scale than intended, leading to discipline fragmentation.
What does ‘cognition = information processing’ mean for the field of cognitive science?
By viewing cognition as a form of information processing, cognitive science united diverse disciplines (such as linguistics, psychology, computer science, etc.) under a singular notion, allowing a unified discipline.
What are the two seminal pieces of work which experimental psychology is rooted in?
Wundt’s ‘Principles of Physiological Psychology’ and Fechner’s ‘Elements of Psychophysics’; see also: Wundt’s Institute of Experimental Psychology, which was the first experimental psychology laboratory.
What was the general significance of experimental psychology (in the late 19th century)?
It produced (briefly) a broad, unified science; psychology fragmented when this ‘definition’ overextended to cover different methodologies.
Define: experimental psychology
The branch of psychology concerned with the scientific investigation of basic psychological processes such as learning, memory, and cognition in humans and animals
Define: cognitive science
The study of thought, learning, and mental organization, which draws on aspects of psychology, linguistics, philosophy, and computer modeling
Define: cognitive psychology
The study of mental processes such as “attention, language use, memory, perception, problem solving, creativity and thinking.”
What is cybernetics and why is it important to cognitive science?
The aim to study adaptive behaviour of intelligent agents by employing the notions of feedback and information theory; Cybernetics creator Norbert Wiener organized the Macy Conferences which brought together multiple disciplines who worked to understand the general working of the human mind (important for the conferences which inspired cognitive science)
How does using the idea of information processing work to unite cognitive scientists?
A critical feature of cognition now involves representation/symbolism; despite using different methodologies to study this aspects of information processing, it unites these various disciplines and differing methods, simply because they are all striving to answer the same questions (ie. how symbolism works within IP)
How does classical cognitive science interpret ‘information processing’?
information processing is ‘rule-governed manipulation of symbols’; heavy reliance on the computer metaphor for information processing
Define: a well-posed problem
A problem which has unambiguously defined states of knowledge and goal states, as well as explicitly defined operations for converting one state of knowledge into another
Define: an ill-posed problem
A problem which is deeply ambiguous, has poorly defined knowledge states and goal states, and involves poorly defined operations for manipulating knowledge
How does connectionist cognitive scientists differ from classical?
Proposed a cognitive architecture that is qualitatively different from the one which is inspired by the digital computer metaphor; instead, connectionists looked at the biology of the brain, the neurons and the way in which they function (the artificial neural network)
Define: artificial neural network
A system of simple processors, analogous to neurons, which operate in parallel and send signals to one another via weighted connections that are analogous to synapses; signals detected by input processors are converted into a response that is represented as activity in a set of output processors; connection weights determine the input-output relationship, but are not programmed, and instead used a learning rule. Artificial neural networks learn from example.
How do the classical and connectionist view of cognitive science remain the same?
Both are still concerned with cognition as information processing! Connectionists only go on to imply that brains are not serial digital computers.
