We use Pavlovia to host PsychoJS experiments, created with PsychoPy Builder. Following is a list of “standard” tasks we use in a battery aimed to gauge a wide variety of cognitive and sensorimotor function:
Measures impulse control, as well as processing time. This task involves refraining from responding to 20% “No-Go” stimuli, embedded in 80% “Go” stimuli.
Measures working memory and working memory capacity; it requires participants to indicate whether the current stimulus matches the one from “N” (here 1, 2 or 3) steps earlier in the sequence.
Measures action inhibition and cognitive control of movement. It involves reaching targets with a cursor that is mirror-reversed (i.e. cursor moves left when moving the mouse right).
Measures the cost of switching from one task to another, both in reaction time and accuracy. It compares performance between switch trials and repeat trials, as well between a task-switching block and single-task blocks.
Measures top-down attentional processes incolved in serial search. This task involves indicating if the target letter “T” is present among 6, 12 or 18 symbols (such as L’s) or not (50% - 50%).
Measures visuomotor acuity by having participants quickly navigating a cursor (by moving a mouse) along a narrow-curved tunnel without touching the edges. Here we look at the speed-accuracy trade-off in this skilled task.
A common neuropsychological tool, assessing multiple processes such as visual search, speed of processing, mental flexibility, as well as executive functioning. Participants move a mouse cursor from 1 to 9 and A to I, interleaved: 1-A-2-B-.. etc.
A popular task in cognitive psychology to measure decision making and executive function in the face of uncertainty. Pick a card from 1 of 4 decks, all of them always give a reward, but there are sometimes also losses of various size.
