Basic navon task

This script runs various examples demonstrating the persisting Uniformity Illusion, protocol by Nina Fitzmaurice.

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.

This is code for the replication of Seli et al. (2016), which is part of the Collaborative Replication and Education Projects (CREP). I share this for other to try out and use.

Note that this public experiment only involves 2 blocks of 45 trials for piloting purposes. The code in the routine SetBlockLengths allows you to change this (to 20 if you are replicating Seli et al., 2016).

Also note that I disabled actual submitting of data by Never stopping the routine Debrief. This means you can only exit the experiment by pressing 'Esc' and closing the browser window. My settings on Pavlovia are such that in that case no data is saved. If you use this for your own experimentation, you should in the routine Debrief change the settting of Debrief_mouse: 'End routine on press' to 'valid click'.

Based on Hüpen et al 2019, differs from a standard BART in that the Balloon dynamically increases in size automatically, the participant presses key to stop the balloon inflating.

The Simple Reaction Time Task (Deary & Liewald, 2011)

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.

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
