| - | Connectionism, today defined as an approach in the fields of artificial intelligence, cognitive psychology, cognitive science and philosophy of mind which **models mental** or **behavioral phenomena** with **networks of simple units**(([[http://www.wordiq.com/definition/Connectionism|wordiQ: Connectionism - Definition]])), is not a theory in frames of [[learning_paradigms:behaviorism]], it **preceded** and **influenced behaviorist school**. Although it is today used in different contexts (mostly referring to neural networks and artificial neural networks that have not emerged until second half of the 20th century) it has origins dating as far back as Greek philosopher Aristotele, who claimed that memory is composed of simple elements connected in a variety of ways(([[http://books.google.hr/books?id=u6j6HTS-rVQC&pg=PA47&dq=J.+A.+Anderson,+A.+Pellionisz+and+Rosenfeld,+E.+Neurocomputing+2&hl=hr&ei=G6drTezgJMO58gPTv-nyBw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CCkQ6AEwAA#v=onepage&q&f=false|J.

| Thorndike later changed some of his views admitting that he was wrong and that negative reinforcement (punishment) does not really lead to any kind of learning. This had great influence on educational process helping to end the practice of punishing the students for incorrect answers. This laws have set the **basic principles** of **behaviorist stimulus-response** views on **learning**. | Thorndike later changed some of his views admitting that he was wrong and that negative reinforcement (punishment) does not really lead to any kind of learning.

| - | Another point of Thorndike's interest in the first two decades of 20th century was the **[[:glossary#transfer|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 by which he showed knowledge transfer is specific rather then general and will not occur unless learned problem and given problem share many characteristics. 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//). | + | Another point of Thorndike's interest in the first two decades of 20th century was the **[[:glossary#transfer|transfer of practice]]**, later often referred to as //transfer of learning//.

| Guided by the principle that "//whatever exists at all exists in some amount//"((Thorndike, Edward L. Individual differences. Psychological bulletin. 1918.))Thorndike has introduced a number of tests of knowledge and intelligence. His //CAVD// (completion, arithmetic, vocabulary and directions) test set the major principles and standards of modern intelligence tests. | Guided by the principle that "//whatever exists at all exists in some amount//"((Thorndike, Edward L.
