Description
The Attentional Blink task as run in the RobbinGobblin study (Bavelier lab TypeScript implementation, prebuilt browser bundle). Letters stream at ~100 ms SOA (each flashed ~33 ms) in RSVP: one letter is white (T1) and must be identified by typing it, and participants also report with 0/1 whether a second target (an uppercase letter) appeared anywhere in the stream. Each trial contains 17 items; T1 position varies (4 or 6) and T2 lag varies (1–8) with 40 T2-absent trials per sequence; the 120-trial sequence is fixed per study phase (randomSequence1 for pre-test, randomSequence2 for post-test) and split into 2 blocks with a break, preceded by practice. Trials are self-paced (space to start). Letter size derives from a pixels-per-degree value; note that, exactly as in the original study deployment, the bundle reads window.pixelperdeg while the page sets window.pxperdeg, so the hardcoded 32 px/deg fallback is what runs — preserved verbatim in this port. Data save failures already fell back to a JSON download in the original; the port keeps that behavior for all data.
