Transfer-appropriate processing

Transfer-appropriate processing, also referred to as TAP, is a type of state-dependent memory specifically showing that memory performance is not only determined by the depth of processing (where associating meaning with information strengthens the memory; see levels-of-processing effect), but by the relationship between how information is initially encoded and how it is later retrieved.

Further explanation

Memory will be best when the processes engaged in during encoding match those engaged in during retrieval. Transfer-appropriate processing (TAP) argues that to have memory successfully recalled there needs to be a successful encoding process. There has been an argument among cognitive psychologists that suggests that the encoding process and retrieval processes are substantially similar. In an experiment that tested TAP researchers found this argument to ring true. They found that successful memory retrieval backs up the encoding process, which therefore has a similar effect on both the retrieval and encoding function. This experiment also pointed out that there are certain variables to consider when looking at TAP because they greatly limit the effectiveness of the retrieval and encoding processes. They believed that to change TAP into a broader form, you would have to question whether the two processing forms actually coincide.[1] Also, TAP is an information-processing action that occurs in two stages; the first includes the procedures that should manipulate the information that coincides with the task activity, and the second stage focuses on the experience that the task activity created. Meaning, that we do not process stimuli all at one time, but instead break it down into a series of responses.[2]

History: the beginnings

In 1972, Fergus I. M. Craik and Robert S. Lockhart completed studies that went against the idea of multistore theories and were in favor of levels of processing when it comes to the human memory. Craik and Lockhart's studies were some of the first studies completed dealing with Transfer-Appropriate Processing, which is now popular because of their ideas. Craik and Lockhart explained that the theory of multistore had very little evidence when it came to capacity, coding and retention. Instead, they proposed that memory involves level of processing. They concluded that we are always building from what we already know through our senses, patterns, and stimulus. Craik and Lockhart completed 10 experiments where participants processed different words by answering questions about them. Depending on the word, the response could be shallow or deep. After this section of the experiment was complete, participants were asked to randomly recall words. They were able to conclude that participants remembered positive and deeper responses more easily.[5] Next, Craik continued his work with Endel Tulving in 1975. They tested subjects individually for perception and speed. Participants had a word revealed to them for 200 ms. through a tachistoscope. Before exposure, questions were asked about the word. These questions were meant to create shallow or deep reactions about the words for the participants. After this was complete, the participants were then asked questions about the words. After these random questions, the participants were asked to recall the words. It was assumed that deeper level questions would be recalled more often. Through four separate experiments, Craik and Tulving found this to be true.[6]

Experiments

This phenomenon has been shown by various experiments:

Problems with transfer appropriate processing

Although this theory has many experiments backing up its reliability, many researchers are questioning the levels of processing that TAP seems to fall into. The levels of processing have been under speculation for the fact that they seem untestable and unfalsifiable. They argue that these processing effects are "circular" in the sense that deep processing can be considered as just better remembering. They believe that much of the questionability of the processing effects lies between the encoding specificity principle and TAP. The researchers argue that these processing systems function much like Darwin's natural selection theory in that the "fitness" of a species and the "depth of processing" in the levels of processing cannot fully predict the final outcome, meaning the survival and retrievability of the species or the information processed. They have found that TAP is still vulnerable to this same type of circularity because it lacks a precise and definite definition. Basically, TAP can only be identified as happening only AFTER retrieval has occurred. Roediger and Gallo argue that after 30 years of research, they still cannot identify why or how we get the typical levels-of-processing effect. However, they still believe that even with these doubts that memory retrieval can be studied and subjected to experiments with "specified" retrieval conditions. Therefore, the levels-of processing effect that TAP falls under supports that the "greater survival" of deep processing most likely occurs, which means that if they had any doubts about transfer-appropriate processing, they should consider the fact that retrieval has more of a range than a semantic processing theory would support, and more than likely thrive and survive![11]

Examples

An example of TAP can be compared to the theory of natural selection presented by Darwin in the section above. This means that if a certain species is "fitter" than the other species, then that fitter species is more likely to continue to adapt to future environmental situations. Lockhart, who refers to this phenomenon, suggests that if you compared a rabbit and a koala that a rabbit would thrive and survive in many environments whereas the koala has worked itself into a "narrow ecological niche." This means the rabbit would excel at surviving because it has a wider range of flexible qualities. Of course you could argue that there would be certain areas that the koala would thrive in, but they are not as numerous as the survival qualities of the rabbit.[12]
