Working Memory Effects
Caffeine has been thought to have some benefits when testing working memory by investigating the tip of the tongue effect, the idea being that, if caffeine were present in one's system, then one would be less likely to experience tip of the tongue effect, or the feeling of knowing a familiar word but not being able to immediately recall it. Previous research suggested that the tip of the tongue phenomena can be corrected for with the use of caffeine, and that caffeine could help one to more quickly retrieve the word they are looking for. Current research refutes previous research accrediting evidence to priming a phonological loop within the working memory opposed to caffeine enhancing STM capacity. A study has found that there are more correct tip of the tongue answers with a caffeine group than those of the control group. The finding is not that caffeine improves performance; it was finding the priming of the phonological-system-effecting responses. When attempting to comprise tip of the tongue effects, subjects were primed with similar-sounding words to the target word; as a result, priming the target word was reached faster regardless of caffeine intake.
