Object-Location Memory Task (Web)

Browser-native companion to T000059-object-location-memory, powered by the shared psyflow-web runner.

Alignment

• Same slug, title, object-to-position-assignment variant, 19-item object pool, ten-object arrays, condition meanings, stage order, timing, response mapping, and score identity.
• The browser task preserves one practice and two scored arrays in each of the two encoding conditions.
• Browser rendering uses pixel dimensions corresponding to the local visual hierarchy; serial trigger hardware is omitted.

Trial Flow

fixation (500 ms) -> study array (30 s) -> retention blank (500 ms) -> 10 object-position assignments (10 s max each) -> optional practice feedback -> ITI (500 ms)

Data

Reduced output preserves one logical row per ten-object array with condition, practice status, object/location plan, query order, item responses, correct count, assignment accuracy, percentage mislocated, mean RT, and conventional response fields.

Runtime
