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).
