Digit Span Task

Digit Span Task

This is a fairly typical implementation of the digit span forward task, similar to what one might encounter in a neuropsychological test battery. The task takes less than 5 min and can be done on a PC with a mouse or on a large touchscreen (tablet or large mobile phone). The digit span is reported at the end of the task.


Lexical Decision Task

Lexical Decision Task

Fairly complete implementation of a typical lexical decision task, which takes about 6 min. It is suitable for use in lectures, where the audience can do the task on a laptop (keyboard). Because keyboard responses are required, the task cannot be taken on a mobile phone. Mean reaction times to words and nonwords are reported at the end with total correct responses. Individual subjects can also download their own data in a format that can be imported into a spreadsheet, like Excel or Google Sheets.
