Text Input using text and code component

This is a simple demonstration showing how to take keyboard inputs and present them on screen using a text component.

You will be presented with a target word. Following the target presentation, you will be asked to type the target word on screen, from memory.When you have finished typing the word, press "return" to end the trial.

test

The Jena Voice Learning Test (JVLMT) is a 22 min standardized tool to measure human voice memory capacity. It was devoloped by Humble et al. (2022). For more information see https://osf.io/cyr23/

memorize a sequence of colored squares

Go/no-go task based on Redick et al.’s (2011) article “Working Memory Capacity and Go/No-Go Task Performance: Selective Effects of Updating, Maintenance, and Inhibition”.

Detect key lifts and durations locally and online

In this study you will become familiar with a few pictures of faces and do a short change detection task comprising a flicker paradigm. After signing up, you will receive an email with a link to the task. IMPORTANT:

This study cannot be done on a tablet or phone, as you will need to use a keyboard. Please use a computer to participate. If you have Autism Spectrum Disorder or any disorder that affects your face perception, you will not be able to participate.

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.

A small study for spatial Reasoning

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).
