Measures short-term/working memory
Paired recall (free) task (PRf)
How do we recall words from our memory?
Please refer back to the Paired Recall (Cue) Task Background section. The paired free recall task is different from the paired cued recall task in that participants are asked to remember as many stimuli as possible, without any word cues. This paired associate learning paradigm can also be used to understand the nature of associations in memory and to examine the nature of forgetting.

Parameters
The following features can be tweaked (default values in parentheses):- Welcome message
- Task instructions
- Memorize instruction footer
- Recall instructions
- Thank you message
- Color of word to memorize
- Size of word to memorize
- Whether or not to show custom word pairs
- Custom word pairs (by default, no custom words)
- Whether or not to randomize trial sequence
- Duration of time that word pairs are shown during learning phase (2500ms)
Note: Default implementation has just 5 word pairs that are done in a fixed sequence (no custom words)
If additional word pairs are included, default is to randomize their order
What data is collected? How is it scored?
The following variables are recorded:
- numberOfUniquePairsSubmitted
- numberOfCorrectAnswers
- numberOfWrongAnswers
- percentOfCorrectAnswers
- meanResponseTime
Percent of correct answers is on 0-100 scale. Average response time is calculated from all recall trials. Note that only unique submissions are considered, so participants are neither rewarded nor penalized if they submit the same pair more than once.

What participants see before taking the task
In this task, you are asked to remember and recall word pairs.
What participants see after taking the task
The paired free recall task is a learning paradigm that measures participants’ memory of word pairs, without any prompting.
Aggregate Variables
These data are automatically written to a csv file upon completion of the task
