General notes

This is an update with many exciting new possibilities in both the experiments and surveys. The main improvements are the option to display multiple survey questions on one screen and in experiments, you can now use array variables, which massively enhances the possibilities of programming experiments.

General online interface

  • Many improvements in the the easymode

New in experiments

  • Many new instructions for working with arrays. This makes it possible to have a flexible way of randomisation. For example, it is now straightforward to make random displays of stimuli, such as in the visual search task (an example of this task using arrays is available). Documentation here.

  • The variable UNDER_MOUSE will contain the value of the stimulus on which a participant clicked. Previously, this could only be done with the bitmap-under-mouse instruction, but just using UNDER_MOUSE is easier. Documentation at end of set instruction, look for UNDER_MOUSE.

  • You can now set also timestamps in the block section. The advantage is that you can now easily track the time a participant spends on a block.

  • You can also "save" within blocks, which is sometimes useful, for example to save an array of collected data.

  • You can use strings in save lines and you can use numbers. This is sometimes useful.

New in online surveys

  • You can have multiple questions on one page (via easymode or as code page: begin and page: end). Documentation here

  • You can have the question text (q:) above the image or video, rather than only underneath it. This can be done with the option o: qf in your survey script, or click the tick box in your easymode (under general options).

  • In progress: Separate saving of personal information, such that emails cannot be linked to the content of the survey. This can be done with the option o: sep, or click the tick box in your easymode (under general options).

  • In progress: Better styled sliders in range questions. This is especially relevant for mobile phones. Just look what they look like, it is much better than in previous version and should always fit on mobile phone screens.

  • Unlike in version 3.1.0, the o: end option in info type will lead to a survey data file that is recorded as "completed"

  • In surveys, you can now use a modulo operator in calc in set questions. Check here (look for the word modulo).

  • In analyze, you can now set the value of what a correct response is (not just the default value 1, but you can choose one yourself).

  • The spacing between items in a check question is better than in the previous version.
