![]() ![]() *Hint: you can ` generate a random letter in python `_ or use a random integer to index a letter from a list e.g. Turn this digit span task into a letter span task using code. Your entire experiment should now look like this: Exercise ¶Īdd a routine to the start of your experiment and ask participants to type their name and occupation. Let’s allow 5 seconds for recall by setting the duration of this component to 5 seconds. This indicates that participants can edit the content of the textbox. Make sure to have the “Editable” field selected. Add a routine called “recall” and inside this routine add a textBox component. In this experiment, we are going to allow participants to type responses. We load our conditions spreadsheet into the Conditions field of our outerloop, in our inner loop we use the variable seriesLen in the nReps field (note that we do not need to start this field with a “$” because the field already contains one in the name). The inner loop, we will name “stimuli” the outerloop we will name “trials”, this is because our outer loop represents each trial and the inner loop represents the series of digits presented within a trial. OK now we want to wrap two loops around this routine. All we would need is to add a code component, change type to JS and type random = Math.random in the Begin Experiment tab. This might not work online, instead what we could do is use int(random()*10) which is easier to translate into Javascript.

How it works: With digit span, the evaluator dictates a series of numbers, and the child has to repeat them back in reverse order.If the examiner says 9, 6, 3, the child has to repeat the sequence back as 3, 6, 9.
