Data saving is not built in

This task collects experimental data but does not save it automatically. If you deploy this task for your study, you must implement your own data persistence mechanism (e.g., server-side logging, database, or file export).

Description

Participants follow instructions involving different semantic categories (animals, fruits, vehicles), stimulus modalities (auditory, visual, visual-enhanced), task types (colour, size judgement), and response mappings (left, right). The design uses four orthogonal factors to investigate how the brain processes instruction-guided semantic decision-making. The experiment consists of 4 blocks of 54 trials each, where participants view image triplets and respond according to the displayed instruction. A complementary 2-back working memory task (OpenSesame) is administered before the fMRI session.

Task Outputs

What it measures

Investigate neural substrates of instruction-following during semantic decision-making, examining effects of semantic category, stimulus modality, task instruction type, and response mapping.
