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.

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.

Grade B: every graded test has at least grade B published evidence. 1 test has grade A evidence and 3 have grade B.
Grade A needs at least 25 test-retest papers and 25 registered clinical studies for each test. Probabilistic Reversal Learning has 15 test-retest papers; Iowa Gambling Lite has 23 test-retest papers; Balloon Risk has 13 test-retest papers.
Grade B means at least 8 test-retest papers, and either 5 registered clinical studies or 150 reliability or validity papers.
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
- Delay discounting
- Reward learning and reversal
- Decision-making under uncertainty
- Risk taking
Suited to: Decision-making and reward research
Research areas: Decisions and reward, substance use and impulsivity
Example report
Participant report
Example data| Test | Main score | Result | Session quality |
|---|---|---|---|
| Delay Discounting | Area Under the Curve | 41% | Valid |
| Probabilistic Reversal Learning | Perseverative Errors | 7 | Valid |
| Iowa Gambling Lite | Net Score | 22 | Valid |
| Balloon Risk | Adjusted Average Pumps | 31.45 pumps | 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
