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.

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.
B

Grade B: every graded test has at least grade B published evidence. 1 test has 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. Hidden Shapes Test has 23 test-retest papers and 1 registered clinical study; Rod and Frame Task has 13 test-retest papers and 5 registered clinical studies.

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 and 2 November 2026 from OpenAlex and ClinicalTrials.gov. See every test's counts or every battery's grade

What it measures

  • Contrast sensitivity
  • Finding shapes hidden in a pattern
  • Visual field dependence

Suited to: Visual perception research

Research areas: Aging and dementia

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
