Psychstudio news - April 2020

Fresh new features for April:

Stimulus management and design improvements

  • New Compound component groups allowing you to combine two or more component groups into a single compound component. This allows a single stimulus to contain a group or groups composed of two or more related components. Effectively, stimuli can now be composed in a heirarchy of compound components. This may not mean much if you've never needed such a thing, but if you do find yourself needing multiple sets of related stimuli in the same trial, you'll be thankful you can do such a thing :)
  • All random stimulus composition strategies have a new counterpart, namely "recompose". In the past, a stimulus set was generated only once, and when called upon again in a different trial block, was used again in it's original composition. Now recomposition is granular, meaning any stimulus group in any part of the hierarchy in a stimulus set can be set to a number of different recomposition strategies when called by any trial block.
  • Stimulus sets can now be individually customized by each set of trials (only available on compound components). Partial re-composition of compound stimulus sets allows you to recompose a subset of compound items isolated to this trial set only. This kind of re-composition strategy might be handy when using the same stimulus set for practice and test. For example, a paired associate task where you're testing participants on their ability to recognize seen/unseen associations.

New range slider

New range slider question type providing a simulated analogue range slider. The new slider has plenty of cusomizations available (including the ability to hide the handle).

As always, if you'd like to request a feature, discuss an experiment's design, or if you have any questions about how to implement something, please email me at or reply to this email. Alternatively, you can contact or follow me on twitter.
