Tests in order

Participants take the tests in this order, each with its standard settings. Changing, reordering or adjusting a test makes the study a custom study.

Timed tests: participants need a desktop or laptop with a mouse or trackpad. The app checks each participant's device before the first test.

The 4 orders of a balanced Latin square, each test as its number in the list above
Order	1st	2nd	3rd	4th
1	1 Food-Picture Dot-Probe	2 Food Delay Discounting	4 Stop-Signal Task	3 Go/No-Go Task
2	2 Food Delay Discounting	3 Go/No-Go Task	1 Food-Picture Dot-Probe	4 Stop-Signal Task
3	3 Go/No-Go Task	4 Stop-Signal Task	2 Food Delay Discounting	1 Food-Picture Dot-Probe
4	4 Stop-Signal Task	1 Food-Picture Dot-Probe	3 Go/No-Go Task	2 Food Delay Discounting

A study run in this square can measure each test's position effect and the carryover each test leaves on the next.

Numbers are places in the list above. A study started from this battery gives everyone that order, or rotates it and stays this battery.

Published evidence

A battery takes the grade most of its tests reach. A minus means some tests have a lower grade, and a battery is never more than one letter above its weakest test. The study builder grades every study the same way.

A−

Grade A−: most graded tests have at least grade A published evidence, and the minus means some have a lower grade. 3 tests have grade A evidence and 1 has grade B.

Grade A needs at least 25 test-retest papers and 25 registered clinical studies for each test. Stop-Signal Task has 23 test-retest papers.

Grade A means at least 25 papers report its test-retest reliability and at least 25 registered clinical studies use it as an outcome.

Grades describe the published research on each task, not this battery or ConductCognition's version of it. Source: ConductCognition test census 0.39.0, counted 31 October 2026 from OpenAlex and ClinicalTrials.gov. See every test's counts or every battery's grade

Example report

Participant report

Example data

Test	Main score	Result	Session quality
Food-Picture Dot-Probe	Attentional Bias to Food	7 ms	Valid
Food Delay Discounting	Area Under the Curve	28.2%	Valid
Go/No-Go Task	d-Prime	3.21	Valid
Stop-Signal Task	Stop-Signal Reaction Time	353 ms	Valid

No test in this battery has a reference group yet, so the report shows raw scores.

In a study, the report lists every score of each test, a percentile where a published norm covers the test and the participant's age, and each session's quality.

Price

Each participant uses one credit, however many tests: $0.99 for academic research or $2.49 for commercial research. Every account starts with 10 free participants, and yearly plans include participants each year. Compare plans
