![]() It’s then very difficult to map findings from brain studies onto cognitive models. Others still, study individuals who experience severe memory deficits due to, for example, brain trauma or infection. In addition, while cognitive psychologists investigate memory using laboratory-style experiments, neuroscientists investigate the living brain as it learns and recalls information. This means that one researcher might investigate long-term memory, another short-term memory and a third working memory and not always are the fruits of this research used to attempt a grand unifying theory of memory, so to speak. One of the major issues we face when getting to grips with working memory is that for decades researchers have occupied themselves with looking at their own particular area of memory. The assumption here is that the secondary task increased load, making it harder to focus on the primary task. ![]() The secondary task would, unsurprisingly, slow response times. Sometimes, participants would also be asked to perform a secondary task simultaneously, such as repeating the the the out loud. ![]() The time taken to respond could be seen as a measure of the effectiveness of the volunteers working memory. Participants would be shown a set of statements, like the ones illustrated below, and were then asked to decide if the statement was true or false. We can quite easily demonstrate working memory using everyday examples because we use working memory for everyday tasks.Ĭognitive psychologists Alan Baddeley and Graham Hitch would investigate working memory through a series of verbal reasoning tasks. In the words one of the pioneers of working memory, Alan Baddeley, what you are doing as you carry out this task is creating a ‘cognitive workspace’ by ‘holding and manipulating information as required’ as you count. Let us then get the easy explanation out of the way by means of a simple question: How many windows does your home have? Now, don’t get up and count each one as you stroll around your home: stay where you are and count the windows in your mind. Simple because it’s very straightforward to demonstrate working memory in action complex because to fully grasp the nature of working memory we really need to understand how it’s related to other types of memory. The answer to this question is both very simple and incredibly complex.
