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.

1
Verbal Learning
AEvidenceMain score: Total Correct Recall
6-8 min
2
Short Story Recall
AEvidenceMain score: Recognition Accuracy
4-6 min
3
Category Fluency
AEvidenceMain score: Unique Valid Words
3-5 min
4
Digit Span Test
AEvidenceMain score: Forward Span
5-7 min

Runs on desktop, laptop, tablet or phone. The app checks each participant's device before the first test. On phones and tablets, each test is compared only with sessions on the same kind of device. A test shows a percentile there once that reference group holds 50 valid sessions in the participant's age band; until then the report shows raw scores and says so.

Other orders

Possible orders: 24
In a balanced Latin square: 4

The 4 orders of a balanced Latin square, each test as its number in the list above
Order	1st	2nd	3rd	4th
1	1 Verbal Learning	2 Short Story Recall	4 Digit Span Test	3 Category Fluency
2	2 Short Story Recall	3 Category Fluency	1 Verbal Learning	4 Digit Span Test
3	3 Category Fluency	4 Digit Span Test	2 Short Story Recall	1 Verbal Learning
4	4 Digit Span Test	1 Verbal Learning	3 Category Fluency	2 Short Story Recall

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.

Grade A: every graded test has at least grade A published evidence. 4 tests have grade A evidence.

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

What it measures

Word list learning and recall
Story memory
Semantic fluency
Verbal working memory span

Suited to: At-home memory research

Research areas: Language and bilingualism, aging and dementia

Example report

Participant report

Example data

Test	Main score	Result	Session quality
Verbal Learning	Total Correct Recall	25	Valid
Short Story Recall	Recognition Accuracy	80%	Valid
Category Fluency	Unique Valid Words	33	Valid
Digit Span Test	Forward Span	6	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
