A study run in this square can measure each test's position effect and the carryover between every pair of tests.

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 2 have grade B.

Grade A needs at least 25 test-retest papers and 25 registered clinical studies for each test. Corsi Block-Tapping Test has 20 test-retest papers; Arithmetic Fluency Task has 22 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

What it measures

  • Visuospatial working memory span
  • Verbal working memory span
  • Working memory updating
  • Planning
  • Arithmetic fluency

Suited to: Child development and education research

Research areas: Child development and education

Example report

Participant report

Example data

Simulated participant aged 10. No reference group covers age 10: the app's norms start at age 18, so the report shows raw scores and no percentile.

TestMain scoreResultSession quality
Corsi Block-Tapping TestForward Span5Valid
Digit Span TestForward Span5Valid
1-Back Taskd-Prime2.68Valid
Tower PlanningExcess Moves16Valid
Arithmetic Fluency TaskCorrect per Minute15 correct/minValid

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
