TestMyBrain GradCPT
Determine your sustained attention
Sustained attention is the ability to stay focused on a dull, repetitive task over time. Lapses — moments when the mind wanders and performance drops — happen to everyone, but people differ in how often they happen.
In the gradual-onset continuous performance test, city and mountain scenes fade into one another; you respond to every city and hold back when a mountain appears. Put simply, it measures how steadily you keep your attention on a task and stop yourself from responding out of habit.
On the following pages, you can determine your sustained attention by completing a short task. It takes about 6 minutes and has to be completed in one sitting.
The results will be provided immediately after you have completed the final trial. Please note that the results you receive can only be reliable to the extent that you work attentively and without help.
This test is part of the validation study for the Quantitative Socionics Inventory. In case of any question, please write an e-mail (contact@quantitativesocionics.org) to the research team.
About this test
- Procedure
- Grayscale city and mountain scenes fade into one another every 800 ms. Respond to every city and withhold your response to mountains (about one scene in ten). 36 practice trials, then a 4-minute sequence of 300 scenes.
- Main outcome
- Discrimination ability (d′).
- Also reported
- Response bias (criterion) · Accuracy · Accuracy, city scenes · Accuracy, mountain scenes · Median RT, correct (ms) · Mean RT, correct (ms) · SD of RT, correct (ms) · Coefficient of variation of RT · TestMyBrain score
- Input
- Keyboard or touch screen; touch devices are offered a choice at the start.
- Study
- Your answers are stored anonymously under the same private profile as the Quantitative Socionics Inventory, so that results can be compared across participants.
