In this experiment participants are required to respond whenever the stimulus (square) location matches its location the previous trial (N-back-1). N-back-2 trials involve responding whenever the location of the square is the same as its location 2 trials before. This task is based on Kirchner (1958) experiment.

In this task participants are required to press either left or right arrow key depending on which way the fish in centre is facing. Participants are required to ignore the direction of the surrounding fish. This is a children version of Flanker Task based on M. Rosario Rueda et al. (2004).

In this task participants are required to memorise and recall number series in order. Participants start out with three 3-digit sequences. If participants correctly recall 2 out of 3 three sequences, they progress to 4-digit sequence trials and so on. If participants respond incorrectly on 2/3 trials the experiment terminantes. This experiment is based on the original digit span experiment by Jacobs (1887).

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.

In this experiment participants are required to respond whenever the stimulus (square) location matches its location the previous trial (N-back-1). N-back-2 trials involve responding whenever the location of the square is the same as its location 2 trials before. This task is based on Kirchner (1958) experiment.

Demo of a visual search task for use online. User can manipulate setsize, target colour, letter orientation. Accuracy and response time recorded.

Created for Eliza Yujun Ng December 2018

Numbers are presented at a rate of one per second. The first digit cannot be 0 Following digits can be 0 but cannot be the same as the previous digit.

If the answer is correct the span is increased for the next trial If the answer is wrong the span is decreased for the next trial

If there are at least two errors at a given span and that represents more than half of the total attempts at that span then the experiment ends, returning a span of one less than the final span attempted.

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