I have a simple experiemnt which displays text stimuli. The stimuli consist of 60 words, but each is presented 3 times (at different latencies), so with a random order, sometimes the same word comes up twice in a row.

Does anyone know of an easy way to pseudorandomise the order (e.g. prohibiting the current trial from having an identical stimuli to the last)? Thanks for any tips!

Best,

Jade

Have a look at my randomisation without repetition online demo

> Hi, I am programming a psychological experiment. In every trial, they read a scenario and see a face photo and hear an answer for the scenario. Scenarios are 20. And there are 4 conditions for the scenarios. (Happy face-Happy sound, Neutral face-Happy sound, Happy face-Neutral sound, Neutral face-Neutral sound) Therefore, All trials are 80. (Scenario 20 \* Condition 4) The point is I need to randomize scenario order without repeating stimuli twice in a row. My problem is that the “random t…
