Simply put, how many digits presented in a row can one remember? This list can be forwards and backwards, and visually or verbally. We must remember information over time to understand the sentence, the paragraph, and the story.Īn excellent way to know how effectively a child is taking in, processing and retrieving information for use within working memory is to administer a digit span test. If working memory is not functioning properly how would you be able to remember information from beginning of the sentence to the end of the sentence and make sense of it all. As we read, we must remember words from earlier in the sentence to make sense of words later in the sentence. Working memory is also important for reading. Perhaps a more contemporary example is remembering a web address so you can type it into your browser window. Ok, I know our phones take care of remembering phone numbers for us nowadays, but such abilities are still important. An excellent, albeit dated, example is repeating a telephone number to yourself from the phonebook to the phone so that you can remember what numbers to dial. Sometimes working memory is also called short-term memory since it refers to being able to remember bits of information for a short amount of time.
The digit span test allows us to better understand the effectiveness of working memory. Working memory is a cognitive system that allows one to store and retrieve information temporarily as you work with it.

#DIGIT SPAN COG LAB DEMO DOWNLOAD#
Please download all folders in this directory for use of any of the tasks (i.e., 'jspsych-6.0.4' and 'img'). Easily customizable variables have been listed at the top of each code.
#DIGIT SPAN COG LAB DEMO TRIAL#
Įach of these tasks can be customized to some extent (number of trials, set size in trials, trial duration etc). A demonstration of the task can be viewed here. Participants are required to memorize locations of colored squares on a grid while simultaneously performing simple symmetry judgement decisions. Methods from this task resemble those described in Oswald et al (2014 ). This is a visuo-spatial WM processing task. Participants have to quickly memorize colors of squares and detect changes. Methods from this test resemble those described in Cowan et al (2006 ). Participants are required to memorize a string of letters while simultaneously performing simple mathematical calculations. This is a verbal-numeric WM processing task. Participants are required to memorize a string of digits and recall them. Methods from this test resemble those descibed in Woods et al (2011 ). This is a verbal-numeric WM storage task. However, given that online experiments have less controlled environments, the reliability of WM measures might be affected.ĭigit span test. Since these tasks are browser based, they can be conveniently used for online experiments (e.g., on MTurk). Paper resulting from these experiments can be found here. These WM tests have previously been used in lab experiments (data from experiments is included in directory). All have been designed on JavaScript using the jsPsych library ( ). Working memory experiment tasks designed on JavaScriptįour classic working memory (WM) tests are included in this directory.
