Thorndike, born in Williamsburg, Massachusetts, was the son of Edward R and Abbie B Thorndike, a Methodist minister in Lowell, Massachusetts. Thorndike graduated from The Roxbury Latin School (1891), in West Roxbury, Massachusetts and from Wesleyan University (B.S. 1895). He earned an M.A.
What is connectionism theory in psychology?
Connectionism theory is based on the principle of active learning and is the result of the work of the American psychologist Edward Thorndike. This work led to Thorndike’s Laws. According to these Laws, learning is achieved when an individual is able to form associations between a particular stimulus and a response.
What is Thorndike’s connectionism theory?
Summary: 1910 – Thorndike introduces his Laws and Connectionism Theory, which are based on the Active Learning Principles. Check the Instructional Design Models and Theories: Connectionism Theory article and presentation to find more.

What is a connectionist network?
Connectionist networks are made up of interconnected processing units which can take on a range of numerical activation levels (for example, a value ranging from 0 – 1). A given unit may have incoming connections from, or outgoing connections to, many other units.
What is the connectionist theory of language development?
A connectionist framework is proposed within which hypotheses about second language acquisition can be tested. Inputs and outputs are patterns of activation on units representing both form and meaning. Learning consists of the unsupervised association of pattern elements with one another.
What is connectionist model in psychology?
Connectionist models, also known as Parallel Distributed Processing (PDP) models, are a class of computational models often used to model aspects of human perception, cognition, and behaviour, the learning processes underlying such behaviour, and the storage and retrieval of information from memory.
What is the connectionist view?
The connectionist views mental processing as the dynamic and graded evolution of activity in a neural net, each unit's activation depending on the connection strengths and activity of its neighbors.
What is a connectionist system?
Connectionist models consist of a large number of simple processors, or units, with relatively simple input/output functions that resemble those of nerve cells. These units are connected to each other and some also to input or output structures, via a number of connections. These connections have different “weight”.
What are the main components of a connectionist model?
Connectionist models consist of a large number of simple processors, or units, with relatively simple input/output functions that resemble those of nerve cells. These units are connected to each other and some also to input or output structures, via a number of connections. These connections have different “weight”.

What is the appeal of the connectionist approach to Modelling cognition?
An immediate appeal of the connectionist agenda was its aim: to construct at the algorithmic level models of cognition that were compatible with their implementation in the biological substrate.
How are concepts represented in a connectionist network?
Representations in connectionist models exhibit continuous levels of activation, and the current state of the model is represented by patterns of activation in various parts of the network. In contrast, the models in Part II (i.e., Fisher & Yoo; Mooney) have discrete, symbolic representations.

What is the theory of connectionism?
Connectionism represents psychology's first comprehensive theory of learning 2) . It was introduced by Herbert Spencer, William James and his student Edward Thorndike in the very beginning of the 20th century although its roots date way back.
What is connectionism based on?
Connectionism was based on principles of associationism, mostly claiming that elements or ideas become associated with one another through experience and that complex ideas can be explained through a set of simple rules. But connectionism further expanded these assumptions and introduced ideas like distributed representations ...
What is the practical meaning of connectivism?
Practical implications of Thorndike's ideas are suggested through his laws of learning:
What is the law of readiness?
Law of readiness. Learning is facilitated by learner's readiness (emotional and motivational) to learn. This potential to learn leads to frustration if not satisfied. This laws have set the basic principles of behaviorist stimulus-response learning, which was according to Thorndike the key form of learning.
What did Thorndike try to prove?
Thorndike tried to prove that all forms of thoughts and behaviors can be explained through S-R relations with use of repetition and reward, without need for introducing any unobservable internal states, yet this is today generally considered incorrect. This learning through response was later in 20th century replaced by learning as knowledge construction. Connectionism was in the first decades of 20th century succeeded by behaviorism, but Thorndike's experiments also inspired gestalt psychology .
What was Thorndike's main interest in the 20th century?
Another point of Thorndike's interest in the first two decades of 20th century was the transfer of practice , later often referred to as transfer of learning. Idea of transfer of practice is to generalize the knowledge or skills and apply them for another problem. Thorndike performed experimental studies showing that transfer of learning will not occur unless learned problem and given problem have many common characteristics. 6) 7) This was the opposite of what school systems mostly suggested at the time: that some school subjects like Latin language and mathematics improve student's mind in general ( doctrine of formal discipline ).
Which connectionist summed his ideas on learning into three laws of learning?
Thorndike, the most commonly cited connectionist, summed his ideas on learning into three laws of learning, which should have accounted for both human and animal learning: 4)
What is connectionism?
Connectionism explains that information is processed through patterns of activation spreading. But what are these patterns? In simpler terms, it means that when information enters your brain, neurons begin to activate, forming a specific pattern that produces a specific output. This forms networks between neurons that will process information quickly without needing preprogrammed algorithms.
What are the properties of connectionist systems?
The basic properties that must be met include: Spreading activation.
What is cognitive psychology?
Cognitive psychology and the computational theory of mind. Cognitive psychology considers the human brain an information processor. This means it’s a system capable of coding the data coming from the environment, modifying it, and extracting new information from it. In addition, the system incorporates these new data in a continuum ...
Is connectionism more complex than what we explained?
To conclude, it’s important to understand that connectionism is much more complex than what we explained in this article. If you’re curious about it, don’t hesitate to continue researching it and its implications .

Although we can try to adapt this theory to new evidence, the computational theory of mind still has faults. This is where connectionism comes in. It’s a much simpler theory than the previous one and explains brain functioning a lot better.
What is connectivism theory?
Connectivism is a relatively new learning theory that suggests students should combine thoughts, theories, and general information in a useful manner. It accepts that technology is a major part of the learning process and that our constant connectedness gives us opportunities to make choices about our learning.
What are the principles of connectivism?
Those main principles of connectivism are: 1 Learning and knowledge rests in the diversity of opinions. 2 Learning is a process of connecting. 3 Learning may reside in non-human appliances. 4 Learning is more critical than knowing. 5 Nurturing and maintaining connections are needed for continual learning. 6 The ability to see connections between fields, ideas, and concepts is a core skill. 7 Accurate, up-to-date knowledge is the aim of all connectivist learning. 8 Decision-making is a learning process. What we know today might change tomorrow. While there’s a right answer now, it might be wrong tomorrow due to the constantly changing information climate.
When was connectivism first introduced?
Connectivism was first introduced in 2005 by two theorists, George Siemens and Stephen Downes. Siemens’ article Connectivism: Learning as a Network Creation was published online in 2004 and Downes’ article An Introduction to Connective Knowledge was published the following year.
What is the hallmark of connectionism?
The hallmark of connectionism (like all behavioral theory) was that learning could be adequately explained without refering to any unobservable internal states. Thorndike’s theory consists of three primary laws: (1) law of effect – responses to a situation which are followed by a rewarding state of affairs will be strengthened ...
What is transfer theory?
The theory suggests that transfer of learning depends upon the presence of identical elements in the original and new learning situations; i.e., transfer is always specific, never general. In later versions of the theory, the concept of “belongingness” was introduced; connections are more readily established if the person perceives that stimuli or responses go together (c.f. Gestalt principles). Another concept introduced was “polarity” which specifies that connections occur more easily in the direction in which they were originally formed than the opposite. Thorndike also introduced the “spread of effect” idea, i.e., rewards affect not only the connection that produced them but temporally adjacent connections as well.
What is the learning theory of Thorndike?
The learning theory of Thorndike represents the original S-R framework of behavioral psychology: Learning is the result of associations forming between stimuli and responses. Such associations or “habits” become strengthened or weakened by the nature and frequency of the S-R pairings.
Why do S-R connections chain together?
A series of S-R connections can be chained together if they belong to the same action sequence (law of readiness). Transfer of learning occurs because of previously encountered situations. Intelligence is a function of the number of connections learned.
What was Thorndike's interest in education?
Thorndike was especially interested in the application of his theory to education including mathematics (Thorndike, 1922), spelling and reading (Thorndike, 1921), measurement of intelligence (Thorndike et al., 1927) and adult learning (Thorndike at al., 1928).
What is connectionism in psychology?
Connectionist models have simulated large varieties and amounts of developmental data while addressing important and longstanding developmental issues. Connectionist approaches provide a novel view of how knowledge is represented in children and a compelling picture of how and why developmental transitions occur. Like other modeling techniques, connectionism has increased the precision of theorizing and thus clarified theoretical debates.
What is connectionist model?
Connectionist models, relying on differential equations rather than logic, paved the way to simulations of nonlinear dynamic systems (imported from physics) as models of cognition (see also Self-organizing Dynamical Systems ).
What is a connectionist approach to cognitive modeling?
Connectionist approaches to cognitive modeling make use of large networks of simple computational units, which communicate by means of simple quantitative signals. Higher-level information processing emerges from the massively-parallel interaction of these units by means of their connections, and a network may adapt its behavior by means of local changes in the strength of the connections. Connectionist approaches are related to neural networks and provide a distinct alternative to cognitive models inspired by the digital computer. After defining key terms, a short history of connectionism is presented, first in the narrower context of cognitive science and artificial intelligence, then in the broader context of epistemology, linguistics, and the philosophy of mind. Next the article touches on the principles of adaptation and learning in connectionist systems, discussing informally the principles of correlational and gradient-descent learning (including the delta rule and backpropagation). The concepts of supervised and unsupervised learning are defined. Then a single example of the connectionist approach is presented: training a network to learn the past tenses of English verbs. Finally, a number of issues in connectionism are discussed briefly: the relation of the symbolic and subsymbolic, distributed representations, computability and Turing machines, the uninterpretability of connectionist networks, their ability to account for sentential and hierarchical knowledge, and their relation to biological neural nets.
Is a vision model an autonomous system?
The proposed model must not be considered as a model of human vision: no hypotheses are made about this point, and the model may be referred to an autonomous abstract intelligent system, in which other components are devoted to the reasoning activities necessary for planning actions, controlling input sensors, coordinating motor activities, and so on.
Is belief revision hard?
Belief revision and updating in general networks were shown to be NP-hard problems (1). Connectionist approaches to finding the MPE are described in Peng and Reggia (2). Systems for generating explanations in belief networks are described in Sember and Zukerman (3), and Henrion and Druzdzel (4). Belief revision in temporal planning applications is described in Berzuini (5), and Kazanawa (6). Qualitative probabilistic inferences are studied in Wellman (7).

What is the law of readiness?
More specifically, the Law of Readiness (see below) suggests that a teacher can only instruct a student if that student is willing to be educated. When a student does not show any signs of readiness, a teacher should provide instructions that will help the student develop.
A Description of Neural Networks
Neural Network Learning and Backpropagation
- Finding the right set of weights to accomplish a given task is thecentral goal in connectionist research. Luckily, learning algorithmshave been devised that can calculate the right weights for carryingout many tasks (see Hinton 1992 for an accessible review). These fallinto two broad categories: supervised and unsupervised learning.Hebbian learning is the best known unsupervi…
Samples of What Neural Networks Can Do
- Connectionists have made significant progress in demonstrating thepower of neural networks to master cognitive tasks. Here are threewell-known experiments that have encouraged connectionists to believethat neural networks are good models of human intelligence. One of themost attractive of these efforts is Sejnowski and Rosenberg’s1987 work on a net that can rea…
Strengths and Weaknesses of Neural Network Models
- Philosophers are interested in neural networks because they mayprovide a new framework for understanding the nature of the mind andits relation to the brain (Rumelhart & McClelland 1986: Chapter1). Connectionist models seem particularly well matched to what weknow about neurology. The brain is indeed a neural net, formed frommassively many units (neurons) and the…
The Shape of The Controversy Between Connectionists and Classicists
- The last forty years have been dominated by the classical view that(at least higher) human cognition is analogous to symbolic computationin digital computers. On the classical account, information isrepresented by strings of symbols, just as we represent data incomputer memory or on pieces of paper. The connectionist claims, onthe other hand, that information is stored non-s…
The Systematicity Debate
- The major points of controversy in the philosophical literature onconnectionism have to do with whether connectionists provide a viableand novel paradigm for understanding the mind. One complaint is thatconnectionist models are only good at processing associations. Butsuch tasks as language and reasoning cannot be accomplished byassociative methods alone and so conne…
Connectionism and Semantic Similarity
- One of the attractions of distributed representations in connectionistmodels is that they suggest a solution to the problem of providing atheory of how brain states could have meaning. The idea is that thesimilarities and differences between activation patterns alongdifferent dimensions of neural activity record semantical information.So the similarity properties of neural activations pr…
Connectionism and The Elimination of Folk Psychology
- Another important application of connectionist research tophilosophical debate about the mind concerns the status of folkpsychology. Folk psychology is the conceptual structure that wespontaneously apply to understanding and predicting human behavior.For example, knowing that John desires a beer and that he believesthat there is one in the refrigerator allows us to expl…
Predictive Coding Models of Cognition
- As connectionist research has matured from its “GoldenAge” in the 1980s, the main paradigm has radiated into a numberof distinct approaches. Two important trends worth mention arepredicative coding and deep learning (which will be covered in thefollowing section). Predictive coding is a well-establishedinformation processing tool with a wide range of applications. It isuseful, for ex…
