In this task participants are required to sort the presented cards based on a rule. The rule is unknown to the participants, however they receive feedback whether their answer was correct. The rule changes after certain amount of trials. This experiment is based on Grant & Berg (1948) experiment.

A demo based on the Balloon Analogue Risk Task. Participants pump a balloon and try to cash in a prize before the balloon pops. Generally used as a measure of risk taking and decision making.

This demo shows how one can use a code component to collect the pressure property of pointer events in JavaScript.

Because the default PsychoJS implementation of mouse events does not collect the pressure property of pointer events, we add two new event listeners to collect the pressure when the pointer first touches the tablet (pointerdown event) and also updates the property while the pointer moves across the tablet (pointermove event).

To try this demo, run it and touch the tablet screen with a pressure sensitive pointer (pen).

visual statistical learning experiments

Participants are presented with a series of numbers and must recall them by typing them into a box. The amount of numbers will increase, making the task harder and harder until we can measure the maximum amount of numbers a participant can remember.

this project has entrainment at retrieval but flicker and no flicker trials are now interspersed. the ISI is also longer

This experiment contains the practice blocks of Experiment 1 from the following paper:

Eaves et al: Transfer of congruency effects between Stroop and multiplication tasks: Evidence that retrieval of multiplication facts requires inhibitory control

This is an illustration of how to run a labjs experiment from pavlovia.org.
