Retroactive interferenceoccurs when learning something new impairs our ability to retrieve information that was learned earlier buy procardia 30mg line coronary heart bypass graft. For example buy 30 mg procardia fast delivery capillaries and alveoli, if you have learned to program in one computer language, and then you learn to program in another similar one, you may start to make mistakes programming the first language that you never would have Attributed to Charles Stangor Saylor. In this case the new memories work backward (retroactively) to influence retrieval from memory that is already in place. In contrast to retroactive interference, proactive interference works in a forward direction. Proactive interference occurs when earlier learning impairs our ability to encode information that we try to learn later. For example, if we have learned French as a second language, this knowledge may make it more difficult, at least in some respects, to learn a third language (say Spanish), which involves similar but not identical vocabulary. Forming categories, and using categories to guide behavior, is a fundamental part of human nature. Associated concepts within a category are connected through spreading activation, which occurs when activating one element of a category activates other associated elements. For instance, because tools are associated in a category, reminding people of the word “screwdriver‖ will help them remember the word “wrench. If they have just remembered the word “wrench,‖ they are more likely to remember the word “screwdriver‖ next than they are to remember the word “dahlia,‖ because the words are organized in memory by category and because dahlia‖ is activated by spreading [12] activation from“wrench‖ (Srull & Wyer, 1989). Some categories have defining features that must be true of all members of the category. For instance, all members of the category “triangles‖ have three sides, and all members of the category “birds‖ lay eggs. But most categories are not so well-defined; the members of the category share some common features, but it is impossible to define which are or are not members of the category. Members of categories (even those with defining features) can be compared to the category prototype, which is the member of the category that is most average or typical of the category. Some category members are more prototypical of, or similar to, the category than others. For instance, some category members (robins and sparrows) are highly prototypical of the category “birds,‖ whereas other category members (penguins and ostriches) are less prototypical. We retrieve information that is prototypical of a category faster than we retrieve information that [13] is less prototypical (Rosch, 1975). Mental categories are sometimes referred to as schemas—patterns of knowledge in long-term memory that help us organize information. We have schemas about objects (that a triangle has three sides and may take on different angles), about people (that Sam is friendly, likes to golf, and always wears sandals), about events (the particular steps involved in ordering a meal at a restaurant), and about social groups (we call these group schemas stereotypes). Read the following paragraph (Bransford & Johnson, [14] 1972) and then try to write down everything you can remember. If you have to go somewhere else due to lack of facilities, that is the next step; otherwise you are pretty well set. It is difficult to foresee any end to the necessity for this task in the immediate future, but then one never can tell. After the procedure is completed, one arranges the materials into different groups again. Eventually they will be used once more and the whole cycle will then have to be repeated. It turns out that people‘s memory for this information is quite poor, unless they have been told ahead of time that the information describes “doing the laundry,‖ in which case their memory for the material is much better.
