Here we include the SRTT task that was built with Gorilla. Once you have created a Gorilla account, you will be able to implement these tasks in your own experiments.
Built with Task Builder 1
This modified Serial Reaction Time Task consists of 2 phases.
Phase 1: Uninstructed learning blocks. Following practice, participants performed the “uninstructed learning” phase of the experiment, which consisted of four 100-target blocks (2 pattern, 2 random), with order counterbalanced. The two pattern blocks each contained a distinct 10-target repeating pattern. Random blocks did not include regular repetitions. Notably, the uninstructed learning blocks were completed before participants received information about the possible presence of patterns. Learning during this phase was therefore likely to be less influenced by top-down processes compared to the instructed learning blocks.
Phase 2: Instructed learning blocks. Following completion of the uninstructed learning blocks, participants were informed that the targets may appear in a pattern and that at other times the targets would appear randomly. Additional text indicated that, at different points during the task, they may develop intuitions (“you may have a sense that [there might be a pattern/dots might be appearing randomly] but may not be sure why you feel that way”) and explicit knowledge (“clear knowledge that the dots [are following a pattern/appearing randomly]”). Participants were instructed to self-report the precise moment at which they developed an intuition and/or explicit knowledge by pressing a “stop key” (“Y” on the keyboard). Upon making a self-report, participants were immediately directed to a separate screen to indicate (1) whether they had an intuition or explicit knowledge and (2) whether they were reporting a pattern or randomness. If they reported explicit knowledge of a pattern, participants were asked to reproduce it. After providing this information, participants were redirected back to the same block and were permitted to stop the block again at any point. Participants could report explicit knowledge prior to reporting an intuition, thus allowing for an empirical assessment of whether intuitions emerged before explicit knowledge. The instructed learning phase consisted of 10 blocks (5 pattern, 5 random) with 105 targets each. Pattern blocks were distinct from the pattern blocks in the uninstructed phase. All blocks ended after the 105th target.
