External Email - Use Caution
Hello experts, We would like to use the optseq 2 to optimize a mixed block and event-related design. Is it possible to use optseq for a mixed design? We are specifically not sure how to specify block duration. What commands shall I use in order to do that? Thank you in advance!
Best, Yu
Emotion Recognition Task. The emotion recognition and perceptual control conditions developed by Greimel et al. have been adapted to include surprise and embarrassment. The task requires participants to either identify the emotions expressed in visually presented faces (emotion recognition) or judge the gender (perceptual control). The emotion recognition task will consist of interspersed expressions of surprise and embarrassment. There will be four blocks, one self-conscious emotion block (e.g., embarrassment and surprise), one typical emotion block to distinguish brain areas of self-conscious emotion to typical emotion (e.g., happy vs. sad), one control block (ask participants to identify gender), one matching shape block. Six images in each block.
There are four blocks of 6 images each.
1) Surprise/Embarrassment faces 2) Happy/Sad faces 3) Identify gender of faces 4) Match shapes We planned to have the Match shapes blocks to interleave all other blocks.
