SEQUEN_FY_IPLM_001

Introduction & Research Question:
I wanted to investigate sequence learning under INTENTIONAL conditions. This follows work by Jones & McLaren (2009) JEP:ABP where participants performed a 2-choice SRT task that, THEY WERE EXPLICITLY TOLD followed a predictive sequence. Half of participants had no sequence and simple psudo-random control trials. The sequence followed a rule, and there were two different rules (between-subjects), either:
1. That the current trial would be in the OPPOSITE location as the trial two trials previous on 2/3rds of trials.
2. That the current trial would be in the SAME location as the trial two trials previous on 2/3rds of trials.
Participants were trained over two sessions then asked a series of structured interview questions regarding their knowledge about any sequences or rules. Reaction times and errors were taken as an index of performance on the task.

Participants:
97

Experiment Software:
Superlab

Method:
Participants responded with two spatially compatible key presses (x and >) to left and right circle flashes on screen, which lit up after a 500msecs inter-trial interval. This training lasted for two sessions. Both of 20 blocks of 120 trials. The first session included 20 training blocks and the second 15 training blocks with the final 5 acting as test where there were no sequences.
