4) Occasions when learning one task makes learning or retrieving another more difficult is called interference. Artificial neural networks have a hard time learning to do more than one thing. A simple example; if a network is programmed to sort the students names in order of the highest grade to the lowest, programming it to do math problems would cause the network to completely forget how to sort the student names. Although many times our learning a new task does not interfere with our ability to learn another task, in connectionist networks this is a problem. When a network is trained to do one thing already, training it for a new task erases its “memory” of how to do the first task. That is called catastrophic interference, and it creates a very hard problem for connectionists. 5) According to the symbol system hypothesis both conscious and intuitive processes are rule-governed and rule-following.
